A kind of maintenance equipment used for front-loading machines in open-pit coal mines

Abstract

The invention discloses a maintenance device for front-mounted machines in open-pit coal mines, which comprises a bottom plate fixedly installed in the ground, a rectangular box is fixedly installed on the top of the bottom plate, and a drain pipe is fixedly connected to one side of the rectangular box. One side of the rectangular box is rotatably connected with a top plate, the bottom of the top plate is in contact with the top of the rectangular box and the top of the ground, the four corners of the top of the bottom plate are welded with supporting columns, and the inner walls of both sides of the rectangular box are Two transverse plates are symmetrically welded, and the tops of the four support columns are respectively welded to the bottoms of the four transverse plates. The beneficial effects of the present invention are: the present invention has a compact structure, can effectively clean the chassis of the front-mounted machine, prolongs the service life, and can adjust the height of the moving plate according to the height of the maintenance personnel, which is convenient for the maintenance personnel to perform maintenance operations, making it possible to Improve maintenance efficiency, clean the chassis, adjust the level of the bucket, change the engine oil more thoroughly, and reduce the labor intensity of workers.

Description

A maintenance equipment for front loading of open-pit coal mines technical field [0001] The present invention relates to the technical field of open-pit coal mines, in particular to a maintenance equipment used for front-loading of open-pit coal mines. Background technique [0002] An open-pit coal mine refers to a coal layer deposited on the surface or shallow layers due to geographic changes, and the For mines, when the ore layer is close to the surface, it is more economical to use open-pit mining, and the soil above the ore layer is called topsoil. not yet open Explosives are embedded in the topsoil strips released, then the topsoil is removed using dredgers, excavators, trucks, etc., which is then filled After the topsoil is removed, the ore layer will be exposed. At this time, the ore blocks are drilled or blasted into pieces. Before use The installation loads the ore into trucks and transports it to the coal preparation plant for further processing. In order ...

Problems solved by technology

[0003] In order to ensure the normal operation of the front-loading machine, it is necessary to maintain the front-loading machine on a regular basis. However, although the maintenance equipment for the front-loading machine in open-pit coal mines on the market can perform basic maintenance on the front-loading machine, there are still the following defects: 1. Effectively clean the chassis of the front-mounted machine. There is a lot of dust in the working environment of the front-mounted machine. A large amount of dirt adheres to the chassis of the front-mounted machine. If it is not cleaned for a long time, the chassis of the front-mounted machine will be rusted and its service life will be greatly shortened; 2. The height of the maintenance equipment cannot be adjusted according to the maintenance personnel with different heights. It is not convenient for the maintenance personnel to overhaul the chassis of the front-installed machine, fasten the bolts of the chassis and replace the parts of the chassis. Labor intensity reduces maintenance efficiency; 3. The oil pan used to hold the pre-installed engine oil is generally shaped, so when removing the oil drain screw of the oil pan, all the old oil cannot be released, and some The old engine oil remains in the oil pan, and the residual old engine oil and new engine oil are mixed together, which will affect the performance of the new engine oil; 4. The level of the bucket cannot be corrected. If the bucket is tilted, it will seriously affect the operating efficiency.
