A rail loading machine

Abstract

The invention specifically relates to a track-type vehicle loading machine; it includes a fixed frame, which is divided into two symmetrical parts, a left fixed frame and a right fixed frame; the two ends of the left and right fixed frames are respectively fixedly connected with Scalable support columns, the left and right fixed frames are connected with two telescopic lifting columns through the two reserved holes in the middle; the upper and lower ends of the left and right fixed frames are respectively connected by two upper connecting beams and two lower connecting beams; each The upper ends between the symmetrically arranged lifting columns are connected with a lifting beam, and two lifting chains are suspended on the lifting beam; the lower ends of the four ends of the fixed frame are all rotatably connected with the wheel set; The front end of the vehicle loading machine described above is provided with a slanting platform; two upper slanting support cylinders and two lower slanting support cylinders are connected between the slanting platform and the fixed frame; the invention is safe and reliable, realizes loading and unloading nearby, flexible adjustment of loading and unloading positions, and high operating efficiency , the amount of auxiliary work is significantly reduced, the operation is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to auxiliary equipment for the preparation work and equipment relocation of fully-mechanized mining working faces in coal mines, in particular to a rail-type car loading machine. Background technique [0002] At present, the preparation work of the fully mechanized mining face and the relocation of equipment have become the core factors that seriously affect the continuity of fully mechanized mining work, especially the relocation of the hydraulic support. The relocation of the mining face or the equipment that takes up the longest time has become an extremely important link that affects the normal production and economic benefits of the mine. [0003] At present, except for a very small number of mines that have the conditions for rubber-tyred vehicles to enter and exit the working face, most production mines use rail auxiliary transportation systems. The traditional process method is chamber hoisting method or fixed inclined ta...

AI Technical Summary

Problems solved by technology

The main problems in the hoisting of fixed chambers are as follows: 1) The excavation volume of the chamber is large and the cost is high; 2) The maintenance of the chamber is difficult; after large-scale excavation, most of the roof is supported by bolts, which is difficult to maintain. During the construction of loading and unloading trucks, it is very easy to cause accidents of roof collapse and injury

3) The accumulation of floating coal and floating gangue is large, and the cleaning workload is large; the hydraulic support is continuously dragged on the floor of the cutting road, causing the floor to be scraped, forming a large amount of floating coal and floating gangue, which affects the transportation of subsequent supports and receives the working surface Due to the limitation of working space, the cleaning workload of floating coal and floating gangue is heavy and becomes more and more difficult with the handling of supports

4) Auxiliary operations such as maintaining the roof, cleaning floating coal and gangue, and hoisting device maintenance take a long time, and the relocation work efficiency is low

5) During the loading and unloading process, the pulley block frame in the hoisting device is loose and dropped, the pulley block shaft is broken, and the wire rope is broken, etc., often occur, causing major casualties.

In order to prevent it from loosening, it is necessary to use concrete to make the foundation in some cases, which increases the workload of bottoming and concrete pouring, and the production cost increases accordingly
