The role of technology is quite large in the national economy. She is a

basic equipment intended for construction and excavation

units (bulldozers, scrapers, etc.).

Each machine is designed to perform the established types of work in

allotted period during which the machine must be in

technically serviceable and operable condition. Complex of works on

maintaining serviceability and restoring serviceability of machines

is called maintenance and repair. Must be reduced to

minimizing downtime of road construction equipment due to technical

maintenance and repair. As a result, the requirements for

reliability of road construction machines, and the role of

operating bases, service centers, dealers and repair

organizations in maintaining equipment in working condition.

A promising form of management in the

in the form of leasing, service, branded repair of machines.

Production of road construction machines, maintenance and

repair turns into a single system complex. Technical process

maintenance and repair will be successful if performed

qualified personnel with excellent knowledge of the design

serviced and repaired machines, methods of troubleshooting and

determination of technical condition of assembly units, technology

repair production. To save locksmiths, from difficult operations and

unsustainable labor methods, machine designs should be

convenient for maintenance and repair. In addition,

labor-intensive disassembly and removal of assembly units to determine their

technical condition, subsequent assembly of components leads to

unnecessary labor and time, increased machine downtime in

maintenance and repair, damage of joints and connections,

Shortening the life of assembly units as a result of repeated

run-in of parts after assembly. All this can be avoided by conducting

technical diagnostics of machines. Acquisition of knowledge by technicians

carried out as a result of a consistent study of the content of the goals

and the tasks of the machine maintenance and repair system. Especially

it is important to learn how to plan, read schedules, and record types

maintenance and repair of machines. Based on them, you can

guarantee safe performance of such works on road

construction machines of any design available in road

construction organizations and road maintenance facilities.

It is important for maintenance personnel to learn to connect the concept

reliability of the machine with its practical manifestation in conditions

use by destination, detect and take action against

elimination of faults of assembly units and components.

"Provision for maintenance and repair of rolling stock

road transport composition "defines the basis for ensuring

serviceability of rolling stock during its operation.

The purpose of this course project is the technological calculation of technical impacts on road construction machines.

Drawing up the layout plan of the designed object

The layout of the production building is usually carried out on a scale: 1:100, 1:75, 1:50, 1:40, 1:25. The plan is carried out in compliance with the construction design, with the indication of the marking of the construction axes and the distance between them, the thickness of the walls, window and door openings. The main parameters defining the space-planning solution are the column grid and

building height. Depending on the design, production buildings can be arceless, with incomplete skeleton and skeleton. In buildings with a reinforced concrete frame, spans can be 6, 12, (less often 9 m), and with a mixed frame - 30 and 36 m. The pitch of columns and building structures is taken as 6 or 12 m. Height to the bottom of building structures (with a multiplicity of 0.6 m) - 3; 3,6; 4,2; 4,8; 5,4; 6,0; 7.2, etc. The length of the zone or section is not a multiple of 3 or 6 m, since it is allowed to install partitions not on columns.

Wall thickness (brick 510; 380 mm, frame 300; 240; 200 mm). Thickness of partitions (made of brick 380; 250; 120 mm, from railway panels 70... 120 mm). Width and height of windows (width 1.5; 2,0; 3,0; 4.0 m, the window height must be a multiple of 0.6 determined by calculation and can be 1.2; 1,8; 2,4; 3,0; 3,6;

4,2; 4.8 m). The height of the room (for sections - 3.6-4.2 m, for zones - 8-12 m). The number of gates, their size and location depend on the peculiarities of the technological process. Normal gate sizes for passing road cars 3x3; 3,6x3,6; 4x4,2; 4,2x4,2; 4.8x5.4 m, Height and width of gate opening should be 0.2 and 0.6 m more than overall, respectively

the size of the machine. The width of the doorways shall be 1-2.4 m and

Height 1.8... 2.4 m. Height of production premises is determined on the basis of overall dimensions of machines and equipment, technology of maintenance of road machines and installation of equipment taking into account the requirements of unification of building parameters.

Construction requirements for the designed facility

The area shall be located in an insulated, heated and well-lit room with an area of not less than 30 m2. The room has to be equipped with the general pritochnovytyazhny ventilation if as process liquid diesel fuel with a temperature of flash of vapors less than 61 wasps is used, the equipment local exhaust umbrellas over jobs of test, adjustment and wash of the diesel fuel equipment is necessary. Air temperature indoors during the cold period of year should not be lower than 18 wasps. The floor and walls of the room shall be lined with materials that do not absorb diesel fuel or its vapors.

The room shall have local or centralized compressed air supply with pressure not less than 0.4 MPa. The room shall be equipped with a reliable grounding circuit for equipment with grounding wire resistance not more than 5.0 ohms. Insulation resistance of electrical circuits must be at least 1.0 Ohm. The floor is recommended in the maintenance and repair area - cement on a concrete base. Room layout is developed on the basis of data on design areas and equipment composition. The posts in maintenance and repair areas are placed so as to avoid maneuvering in the zones, to ensure convenient movement of equipment near the machines and between the posts themselves. The distance between the axes of the posts should be at least 5 m. The width of the passage in the zone with parallel floor posts at the angle of arrangement 900 is determined by the ratio W = 1.2LM, where LM is the length of the machine.


On the basis of the issued task, a design was developed for the repair of fuel equipment with an individual repair method, the production area of ​ ​ the room was 36 m2.

The annual volume of work performed is 51918 people. -h. The accepted staffing number of workers is 9 and ITR is 1. The process equipment of the fuel equipment repair area consists of equipment, tools, instruments and devices selected according to the types and scope of work. The organizational equipment is selected in accordance with the requirements of the scientific organization of labor for the successful and high-quality performance of basic and additional functions.

During the course project, theoretical and practical knowledge on the organization and technology of maintenance and maintenance of road and construction machines was consolidated and expanded.
