Introduction

During the operation of road machines, their working properties are gradually deteriorated due to wear of parts, as well as corrosion and fatigue of the material from which they are made. Failures and faults appear in the machine, which are eliminated during maintenance and repair. This allows you to keep the equipment in a technically serviceable state.

With the increasing level of mechanization of production processes in construction, the introduction of market relations and the self-financing regime, the problem of rational use of machines becomes especially urgent. It is known that the profits obtained by enterprises are largely determined by the efficiency of the use of machines and equipment, and the magnitude of this profit depends on many factors directly related to the level and culture of operation of machines. Such as, for example, the structure and composition of the machine fleet, the strategy for its operation, the accepted methods of organizing maintenance and repair, the selected options for performing mechanized work, etc. Currently, the construction industry uses many types of construction and road machines with high technical and economic indicators. The irrational use of such equipment, and even more so its downtime, leads to a significant increase in the cost of work, a delay in their implementation and, ultimately, a decrease in the profit earned by the enterprise. All this puts the problem of increasing the efficiency of using machines to the fore among other problems of mechanization of production. As the practice of work of advanced construction organizations shows, due to the rational, efficient use of existing technology, it is possible to increase its productivity by 10... 30% compared to the average in the industry and get significant savings from this. And this in turn will lead to a decrease in the cost of production and increase its competitiveness. At the same time, it is important that the optimal operating options for the machines be determined taking into account the influence of various operational factors, feedback and restrictions that you have to face in such tasks. Therefore, the development of new methods and the improvement of existing methods for choosing optimal operating options for machines based on modern mathematical methods and computer applications and taking into account the influence of various production factors is an urgent scientific task that meets the needs of practice.

The objectives of the course project are: calculation of the amount of maintenance and maintenance for the cycle and year, the number of labor costs for maintenance and repair, determination of the amount of labor and the number of posts necessary for the work, calculation of energy needs for the enterprise and its area, calculation of annual costs of lubricants fuel for the entire fleet of machines, as well as preparation of a preventive plan .

Source Data:

Preventive design for maintenance and maintenance of APKS10 autocompressor up to KR = > 35%, Ms = 28 machines; 18 cars work in two shifts; operating time from the beginning of operation Lex = Nf = 2154 reel; climate-Tyumen; operating mode = > change tcm = > 12 hour , for 2017 year.

3.2 Process Description

Daily maintenance includes inspection of the mechanisms and systems of the autocompressor, which affect traffic safety, cleaning, as required filling operations. OW works are used to reduce the number of failures as much as possible, since the failure leads to additional labor costs, transportation of the faulty machine and its subsequent repair.

All machines returning from work are accepted by the KTP duty mechanic, who performs a check inspection of the machine and sends it to the parking lot or to the maintenance area as necessary.

Control operations under the EO include monitoring of the technical condition of the steering, braking system, attachment of units and assemblies, leak tightness of the systems, serviceability of hydraulic equipment, completeness of the machine.

Upon completion of the EO of the machine, the relevant documentation is drawn up. EO is performed after the machine returns from work at interschange time.
