Construction Machinery Equipment Repair and Maintenance Measures

With the support of modern science and technology and advanced mechanical technology, my country’s construction industry has not only developed rapidly, but also construction machinery and equipment are gradually developing towards automation, which has a positive impact on improving the efficiency of construction projects and reducing construction costs. Therefore, the repair and maintenance of construction machinery and equipment has gradually attracted widespread attention and attention. Taking actual projects as an example, this article analyzes the importance of repair and maintenance of construction machinery and equipment, existing work problems, etc., and proposes measures for the repair and maintenance of construction machinery and equipment.

1 Project Cases

The Yueqing Bay Project is a landmark brand project. A large number of construction machinery were used in the construction process of the project. During the on-site construction process, great attention was paid to the maintenance and repair of mechanical equipment. Technical innovations were also made for some mechanical equipment, such as the design and application of the automatic spray curing trolley for the tunnel secondary lining concrete, the transformation and application of the tunnel anchor drilling rig, the design and application of the mobile hexagonal hollow brick dismantling and transportation trolley, the design and application of the fully automatic T-beam maintenance trolley, the design and application of the multi-functional cover plate dismantling and transportation trolley, the design and application of the small-diameter pipeline steel cage rolling welding machine, the upgrade and application of the complete set of paving equipment for the bridge deck concrete leveling layer, the design and application of the mobile sunshade (sun) awning, the design and application of the portable wire retracting rack, the development of the remote monitoring system for safe operation and construction quality at the road construction site, etc. These construction machinery and equipment have high requirements for maintenance and repair.

2 The importance of maintenance and repair of construction machinery and equipment

The maintenance and repair of construction machinery and equipment is the key work content in the construction process of construction engineering. Scientific and perfect maintenance and repair work has a vital impact on the orderly progress of construction and cost control. At the same time, mechanical equipment repair and maintenance is also an important means to ensure the good operation of mechanical equipment and a long service life cycle. Therefore, the repair and maintenance of construction engineering mechanical equipment plays an important role. In the actual construction process, if the working performance and function of mechanical equipment are found to be continuously declining, and the operation and construction are still insisted on, the long-term overload operation will lead to the loss of mechanical equipment function, affecting the construction efficiency, and the safety will be greatly reduced, and there are certain safety hazards. Therefore, in the construction process of construction engineering, it is necessary to do a good job in mechanical equipment repair and maintenance to ensure that the mechanical equipment can always be in a good operating state, so as to improve safety and extend the service life of mechanical equipment. On the premise of completing the construction tasks with quality and quantity, it can also effectively reduce the construction cost expenditure and improve the economic benefits of the construction company.

The weakening of mechanical equipment performance during the actual construction of construction engineering can be intuitively reflected by Figure 1, where B1 and B2 represent the changes in the mechanical properties of the mechanical equipment itself; M1 and M2 represent the changes in the performance differences of mechanical equipment; TB1, TB2, TM1, TM2, etc. represent the performance change time of mechanical equipment.

The performance of construction engineering machinery and equipment is closely related to the construction quality, construction progress, and economic benefits of construction enterprises. Therefore, in the actual construction process of construction projects, it is necessary to pay attention to the maintenance and repair of construction engineering machinery and equipment to ensure that the construction machinery and equipment are always in good operating condition, so as to ensure the orderly development of construction.

3 Problems in the maintenance and repair of construction engineering machinery and equipment

3.1 Lack of sufficient attention

The lack of sufficient attention to the maintenance and maintenance of mechanical equipment is one of the common problems at present. Some construction companies ignore the importance of maintenance and maintenance during the construction process. They often only repair and maintain mechanical equipment when mechanical equipment fails. However, no matter how advanced and high-end the mechanical equipment is, if the daily maintenance and maintenance is ignored, it will not only reduce the safety factor of the mechanical equipment, affect its work efficiency and quality, but also shorten its service life invisibly. Therefore, the maintenance and repair of mechanical equipment must be given enough attention.

3.2 Repair and maintenance cannot be effectively implemented

During the actual operation of construction engineering machinery and equipment, there are many factors that affect its operating status, such as the operators of machinery and equipment, whether the operation is standardized, whether the management mechanism of machinery and equipment is perfect, whether the daily maintenance of machinery and equipment can be carried out in place, etc. These factors will have a great impact on the operating status and service life of machinery and equipment. In the actual construction process of construction engineering, although there is a perfect repair and maintenance mechanism, it is affected by many factors, resulting in the inability to effectively implement the repair and maintenance work. The lack of basic maintenance and repair of machinery and equipment will inevitably cause the loss of machinery and equipment, greatly affecting the safe operation of machinery and equipment and shortening the service life of machinery and equipment. Therefore, whether the repair and maintenance work is effectively implemented must be highly valued by managers.

4 Measures for the repair and maintenance of construction engineering machinery and equipment

In view of the shortcomings in the current repair and maintenance of construction engineering machinery and equipment, in order to ensure the safe operation of machinery and equipment, avoid safety accidents caused by the failure of machinery and equipment and affect the construction quality and progress, this article proposes the following measures for the repair and maintenance of machinery and equipment in combination with actual engineering cases.

4.1 Focus on cultivating the professional skills of mechanical equipment maintenance and maintenance workers

Based on the support of modern advanced technology, the types of construction machinery are becoming increasingly diversified and complex. In the actual construction process of construction projects, it is necessary to focus on cultivating the professional skills of mechanical equipment maintenance and maintenance workers, which can not only improve the work awareness of relevant workers, but also better complete the maintenance and maintenance of mechanical equipment. Therefore, in actual work, regular training and education should be carried out to help relevant technical personnel have a higher awareness of maintenance and maintenance work, good professional quality and sense of responsibility, and be able to improve their own technical level in the process of continuous learning, so as to reduce the probability of mechanical equipment failure in the maintenance and maintenance of mechanical equipment, extend the service life of mechanical equipment, effectively reduce cost expenditure, and thus improve the economic benefits of construction enterprises on the premise of ensuring construction safety and construction quality.

4.2 Strengthen the transformation and upgrading of mechanical equipment

In order to solve the problems and deficiencies in the maintenance and maintenance of construction machinery and equipment, the engineering case in this article solves the relevant problems through the transformation and upgrading of mechanical equipment. It can be seen that strengthening the transformation and upgrading of mechanical equipment is also one of the important ways to solve related problems. With the support of modern science and technology, construction engineering machinery and equipment are constantly optimized and upgraded. However, some companies are influenced by traditional work thinking and concepts and have not upgraded and transformed the machinery and equipment during the construction process. The old machinery and equipment not only have a high failure rate, but also greatly affect the construction progress, resulting in a large waste of resources and seriously affecting the economic benefits of the construction companies. Therefore, in response to such problems, construction companies must strengthen the transformation and upgrading of machinery and equipment in accordance with the actual situation of the construction project. By continuously upgrading the machinery and equipment, the probability of mechanical equipment failure can be reduced, and the efficiency and quality of mechanical equipment maintenance and maintenance can be effectively improved, providing important technical support for maximizing the economic benefits of the enterprise.

Among the many maintenance technologies, laser cladding technology is the best choice. The metallurgical bonding layer formed by alloy powders with different characteristics and substrates not only increases the strength of the original product by 5-10 times, but also resists corrosion, high temperature and wear, which greatly improves the service life of the product.

4.3 Build a scientific and complete organizational maintenance system

In view of the current problem of inadequate implementation of maintenance and repair work for construction engineering machinery and equipment, relevant enterprises must build a scientific and complete organizational maintenance and repair system to ensure that relevant work can be implemented. Specifically, according to the actual situation of construction engineering, a scientific system should be built to reasonably arrange maintenance and repair work, so as to ensure that relevant work is implemented. At the same time, it is necessary to strengthen cooperation with machinery and equipment manufacturers. Manufacturers should not only provide high-quality machinery and equipment, but also complete the training of relevant maintenance and repair technicians to ensure that technicians can solve the corresponding fault problems in the actual operation process. In addition, if a construction project uses a large number of mechanical equipment, an independent equipment management department can be established, which is mainly responsible for the overall scheduling and use of mechanical equipment and the training and management of relevant technicians, so as to form a more complete mechanical equipment maintenance and repair management system.

4.4 Strengthen supervision and management, and strengthen the maintenance and repair management of mechanical equipment

The operation of mechanical equipment in the construction process of construction engineering will face many unstable factors, such as construction environment, climate factors, operator changes, etc. These factors will have a certain impact on the stable operation of mechanical equipment. Therefore, in order to reduce the impact of these factors and ensure the orderly progress of construction, it is necessary to strengthen the supervision and management of mechanical equipment maintenance and maintenance, and continuously strengthen the maintenance and management of mechanical equipment. Specifically: First, it is necessary to pay attention to the cultivation of the professional quality and technical level of technical personnel, and continuously improve the technical level of technical personnel, so as to help them find and solve problems in their daily work in a timely manner, and ensure that the mechanical equipment is always in good operating condition; second, strengthen the supervision and management of mechanical equipment operation, maintenance and maintenance, and urge relevant workers to carry out their work in accordance with unified standards and in a standardized manner, and effectively avoid the impact of factors such as construction environment, technical personnel and climate on mechanical equipment; third, for different mechanical equipment, according to the technical standards and parameters provided by the equipment manufacturer, continuously improve the relevant operating standards and specifications, so as to ensure the safe and stable operation of mechanical equipment, and improve the economic benefits of the enterprise while improving construction safety; fourth, it is necessary to reasonably formulate a reward and punishment system, a responsibility system, and strengthen supervision and management to ensure that the maintenance and maintenance of mechanical equipment is implemented in practice.

4.5 Innovate the repair and maintenance methods of construction engineering machinery and equipment

Some workers in the repair and maintenance of construction engineering machinery and equipment are influenced by traditional work concepts and ideas. The working methods for the repair and maintenance of construction engineering machinery and equipment are relatively simple, and the number of repairs is frequent, the work efficiency is low, and the time cost is high. The common working methods are single-machine maintenance and assembly interchange maintenance. Specifically, single-machine repair and maintenance is mainly for the repair and maintenance of single, independent mechanical equipment when it fails, while assembly interchange is for the mechanical equipment assembly that cannot be repaired and can only be completed by replacing the assembly or new parts. Although these two types of repair and maintenance work have certain advantages, the maintenance duration is long, the quality cannot be effectively guaranteed, and the frequent repairs will increase the time cost and capital cost, which will have a great impact on the construction progress and construction quality. Therefore, it is necessary to focus on innovating the working methods of repair and maintenance of construction engineering machinery and equipment in order to fundamentally solve the problem. Specifically: First, it is necessary to formulate clear standards for the repair and maintenance of construction machinery, quantify the repair and maintenance indicators of mechanical equipment, guide the repair and maintenance workers to carry out related work in accordance with relevant regulations and standards, and at the same time, institutionalize the management of the repair and maintenance of construction machinery and equipment, so as to effectively stimulate the internal driving force of the maintenance workers and achieve the overall improvement of the efficiency and quality of the repair and maintenance of mechanical equipment; second, it is necessary to conduct regular training and summary meetings. On the one hand, it can help the relevant workers gradually improve their work level and ability, so that they can complete the repair and maintenance of construction machinery and equipment more efficiently and with high quality; on the other hand, through the summary meeting, the repair and maintenance work methods can be gradually optimized and improved to ensure the scientific nature of repair and maintenance. At the same time, by accurately troubleshooting the equipment failure voice of construction machinery and equipment during operation, summarizing the most frequent equipment failures, conducting collective research and discussion, and formulating a set of scientific and reasonable repair and maintenance plans, we can fundamentally solve the relevant problems and provide important support for the orderly development of construction engineering.

5 Conclusion

In summary, with the continuous acceleration of the pace of urbanization in my country, construction projects are increasingly developing on a large scale, and there are extremely high requirements for construction machinery and equipment. This requires construction managers and technicians to gradually increase their attention to the maintenance and repair of machinery and equipment, and improve the quality of mechanical equipment maintenance and repair work by continuously improving the working mechanism of mechanical equipment maintenance and maintenance, optimizing and transforming mechanical equipment, etc., so as to effectively improve the economic benefits of construction companies under the premise of ensuring the safety of mechanical construction.
Not only the maintenance of mechanical equipment, but also the selection of energy supply in various ways has become a trend. For example, mining projects that use a large number of electric-driven engineering machinery such as shield machines and crushers will have a lot of natural gas and other wellhead associated gases as the ore is developed. At this time, if gas-fired generators are used to generate electricity using these gases, not only can electricity be supplied to the entire project, but also hot water can be produced by cogeneration of heat and power, and the entire project will be more energy-saving and environmentally friendly.
