Abstract: the use of equipment, management, maintenance and repair stage accounts for the vast majority of the total life cycle of the equipment, to grasp the equipment management, to ensure that the equipment is safe, normal operation, is a fundamental work of the enterprise management work, which maintains the foundation of the enterprise's production and operation, affecting all aspects of the enterprise. Strengthen the management of enterprise machinery and equipment, give full play to the effectiveness of machinery and equipment, mechanical equipment to tap the potential, has important practical significance.

Keywords: machinery and equipment management, repair and maintenance

Machinery and equipment is a vital construction tool for enterprises, but also one of the external image of the enterprise. Ensure that the process of mechanical equipment resources to use the ability to good economic efficiency of the equipment for the production and operation of the enterprise services, is the theme of mechanical equipment management and the central task, but also an important object of enterprise management. Therefore, how to strengthen the management of enterprise machinery and equipment, give full play to the effectiveness of machinery and equipment, tap the potential of machinery and equipment, has important practical significance.

First, the management of machinery and equipment problems

(a) There are potential safety hazards in the management of equipment

Due to the current irregularities, the management system is not fully in place, a part of the business leaders in order to pursue the profits and achievements, and to reduce costs by all means, must be the equipment to update the funds for the reconstruction. Not willing to invest, resulting in abnormal equipment obsolescence, aging phenomenon is more prevalent in the existence of equipment in the existence of hidden dangers, buried in the root of the accident induced.

(B) the gradual weakening of the enterprise's equipment management

The phenomenon of not attaching importance to the management of equipment within the enterprise generally exists. First of all, in the many management of the enterprise, production and operation, safety is undoubtedly placed in the most important position, while the equipment management has become important to say, do the secondary, busy do not "inferior" work. Secondly, many enterprises lack of real both professional skills, but also has the ability to manage the coordination of special talents. Third, the high qualification, strong management ability of the enterprise is now mostly as a construction general contracting unit, objectively withdrawn from the front line of the equipment management work, which is also an important reason for the weakening of the management work.

(C) changes in the workforce, to do a good job of equipment management has increased the difficulty

China's workers from the original enterprise-owned 1-8 level of skilled workers, the vast majority of them did not participate in any training, the wandering soldiers scattered will be similar to the laborers, temporary workers. This part of the personnel quality varies, the performance of machinery and equipment, operating procedures, maintenance and other basic knowledge is very little. Coupled with their work content is mostly contractual and other objective conditions, decided to be completed by this part of the daily maintenance of equipment, maintenance work will not be complete, the daily maintenance of equipment can only stay on the surface.

Two, mechanical equipment management measures

Mechanical safety is from the human needs, in the use of machinery in the whole process (use, maintenance, repair) of the various states, to achieve the physical and mental health of human beings from the hazards of external factors of the state of existence and conditions of protection. For the above several difficult problems, combined with the actual situation of the construction process to propose the following measures.

(a) the correct selection, reasonable deployment

Any kind of machinery due to their own performance, structure and other characteristics, there are certain technical requirements for use. If you can strictly according to the provisions of the rational use of machinery, you can give full play to mechanical efficiency, reduce mechanical wear and tear, extend the service life, reduce the cost of use. For the deployment of machinery between the projects, to do in advance and timely grasp of the demand for machinery and equipment, exit information, arrangements for machinery and equipment in the process of the second maintenance maintenance work, to solve the conflict between the use of good and maintenance.

(B) do a good job of safety testing of special equipment

Special equipment is closely related to personal and property safety, human health, pressure and manned equipment assembly, in the production process, more than the general production equipment has a greater potential for danger. As special equipment is a dangerous equipment, prone to accidents resulting in injury to the operator or others, as well as machinery and equipment, public **** facilities and other major property losses, in order to ensure its normal operation must be carried out on a regular basis and tour testing and inspection, in order to avoid the occurrence of mechanical accidents, to protect the safety of production and life safety.

(C) personnel training, licensed

Personnel training, including operational skills. Training and personnel safety education and training. Personnel training and education work should be planned, deployed, inspected, assessed and targeted: First, we must grasp the construction project machinery operators access to the gate, the three levels of safety education before starting work to do; Second, the preparation of the appropriate knowledge of production safety and safety regulations manual, issued to each operator on the site; Third, the safety of machinery and equipment management personnel to do a good job of training work. At the same time, the safety education and training of relevant personnel should establish the concept of "full safety education and training". No matter what people, as long as directly or indirectly involved in machinery and equipment related production activities, must be subject to safety education and training, up to the leadership, down to the general staff, including even the producer's family members, to let them know the production of labor engaged in the importance of its safety and protection awareness, self-protection awareness and self-protection methods, so that they ideologically recognize the importance of safety, so as to achieve the control of machinery and equipment safety accidents occurring from the source. The company's main goal is to control the occurrence of safety accidents in machinery and equipment.

Third, the economic benefits of mandatory maintenance of machinery and equipment

Maintenance technology requires simple, low-cost, while ensuring that the normal operation of the equipment to reduce the wear and tear of the parts and prolong the service life of the equipment, especially for large-scale major machinery, it is necessary to strengthen the necessary technical maintenance operations in order to eliminate the failure of the hidden danger, to ensure that the normal operation of the equipment. operation. More can reduce a lot of unnecessary costs, greatly improve the economic efficiency of enterprises.

The shorter the service life of the equipment, the higher the reliability, the longer the service life, the lower the reliability. The lower the reliability of the mechanical equipment is prone to failure, the more serious the physical wear and tear of the equipment, the repair of its required cost is also the greater. Modern machinery and equipment is capital-intensive equipment, equipment investment and the use of very expensive, urgent need for economic efficiency of equipment management.

Fourth, the maintenance of machinery and equipment, maintenance methods, measures

First of all, the strong maintenance, zero-waiting engineering system, the main body of its engineering content is: "strong maintenance" as the core, the radiation revision and implementation of the 64 types of producers for the implementation of the main body. The main contents of the project are: taking "strong maintenance" as the core, revising and implementing 64 categories of equipment integrity standards and operation and maintenance regulations with producers as the main executing body, and designating the main production equipment maintenance regulations and other management systems; taking "zero-waiting" as the core, and adding and improving the hardware and software with equipment repair and management as the executing subject. "Zero wait" means: after the equipment failure, the waiting time for maintenance personnel is zero, the waiting time for maintenance spare parts is zero, the waiting time for maintenance tools is zero, and the waiting time for maintenance information is zero. The "strong zero project" for the enterprise also has a high value.

In view of the current situation of mechanical equipment maintenance and the new characteristics of construction enterprises, new circumstances, China has proposed a mandatory maintenance system for machinery and equipment. Mechanical maintenance can improve efficiency, but how to ensure the use of efficiency under the premise of maintenance costs to reach a minimum, and ultimately achieve the optimal economic efficiency of enterprises, the author after a long period of practice and exploration summarized a few suggestions:

Raise awareness, clear mandatory maintenance of the principle of the so-called mandatory maintenance, maintenance of mandatory provisions must be carried out on time, and must not be because of the work of nervousness! And do not arrange time and personnel for maintenance. To carry out modern equipment management education, so that leaders at all levels and the majority of equipment managers understand the integrity of mechanical equipment and service life, largely determined by the maintenance work.

To establish and improve the maintenance system and rationalize the maintenance cycle construction enterprises should take regular maintenance, maintenance, inspection (inspection) system, the implementation of the "maintenance and repair, prevention-oriented" approach, the strict implementation of the scheduled maintenance, regular maintenance, maintenance tours, and maintenance at all levels of the implementation of procedures, low-level maintenance by the operator, high-level maintenance by the repair and maintenance of the equipment, the maintenance of the equipment, the maintenance of the equipment and the maintenance of the equipment. Low-level maintenance is carried out by the operator, and high-level maintenance is carried out by the maintenance personnel together with the machine operator. Only maintenance is done, the chance of mechanical failure is reduced, in order to reduce maintenance costs and improve economic efficiency. At the same time, the maintenance cycle should be based on the use of machinery and equipment to repair the actual situation, collect a variety of data on the use of maintenance, analyze the use of mechanical equipment subsystems standards, the failure of the law and other factors to determine the method of probability of statistical methods, technical and economic analysis and maintenance of the statistical method of operation.

Strengthen the technical management of mechanical equipment maintenance, mechanical equipment has a strong construction period of seasonal, construction operations of decentralized mobility and harsh operating environment. For these characteristics of the equipment, strengthen the maintenance of mechanical equipment, and timely repair is to strengthen its technical management of the main content. First of all, strengthen the maintenance, to ensure that the equipment in good technical condition, to establish a "maintenance on time, according to the level of maintenance, according to the maintenance" idea, highlighting the "scientific, mandatory, predictive", so as to prevent problems before they occur. Secondly, careful repair to ensure timely repair of equipment. In the equipment maintenance work should be equipped with high technical level, experienced maintenance personnel, highlighting the preventive, targeted and effective, pay attention to the assembly process and optimize the repair process.

V. Conclusion

The management of machinery and equipment and mandatory maintenance and maintenance of a complex and comprehensive subject, in addition to good management, use, maintenance, repair off, but also must do the leadership attention, all levels of machinery management personnel, machinery operators, maintenance personnel and related cooperation between the responsibility for clear, only persistent, and Always pay attention to unremittingly, maintain a sense of security and danger, really do "prevention first", we will be able to eliminate the occurrence of major machinery and equipment accidents, to ensure that machinery and equipment safety, quality and efficiency for our construction production services.
