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

Abstract

The invention particularly relates to a rail type car loader. The rail type car loader comprises a fixing frame. The fixing frame is divided into two symmetrical parts of the left fixing frame body and the right fixing frame body. Stretchable supporting stand columns are fixedly connected with the two ends of each of the left fixing frame body and the right fixing frame body correspondingly through preformed holes in the two ends, and two stretchable lifting stand columns are connected with each of the left fixing frame body and the right fixing frame body through two preformed holes in the middles; the upper ends and the lower ends of the left fixing frame body and the right fixing frame body are connected through two upper connecting beams and two lower connecting beams correspondingly,a lifting beam is connected with the upper end between each pair of symmetrically arranged lifting stand columns, and two lifting chains are hung on each lifting beam; and wheel set frames are rotatably connected with the lower ends of the four ends of the fixing frame correspondingly, a sloping bench is arranged at the front end of the car loader, and two upper inclined strut cylinders and two lower inclined strut cylinders are connected to the position between the sloping bench and the fixing frame. According to the rail type car loader, safety and reliability are achieved, nearby loading and unloading are achieved, adjustment of the loading and unloading positions is flexible, the operating efficiency is high, the auxiliary operating amount is obviously reduced, operation is simple, andthe 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...
