Loader for hydraulic supports of fully-mechanized coal mining faces of coal mines

Abstract

The invention discloses a loader for hydraulic supports of fully-mechanized coal mining faces of coal mines. The loader mainly comprises a running mechanism, a supporting mechanism, a hoisting mechanism and a guiding mechanism. The running mechanism comprises wheel set frames, draw bars and the like and is used for traveling during loader transposition operation; the supporting mechanism comprises supporting hydraulic cylinders, supporting column caps and the like and is used for supporting roofs and floors when the hydraulic supports are hoisted by the loader; the hoisting mechanism comprises hoisting hydraulic cylinders, hoisting beams, hoisting wheels and the like and is used for keeping each hydraulic support separated from a platform trolley by a certain distance when the hydraulic support is lifted, so that the platform trolley can access the loader conveniently; the guiding mechanism comprises an oblique table, upper and lower diagonal bracing hydraulic cylinders, positioning frames, limiting frames and the like, is used for preventing the hydraulic supports from being collided with the loader when the hydraulic supports travel and guarantees the accuracy of loading positions. The loader has the advantages that the mechanization degree can be greatly increased, the work efficiency can be greatly improved, the fully-mechanized coal mining face moving time is shortened, the labor intensity of operators is reduced, and accordingly requirements on the continuity of coal mine production and improvement of the economic efficiency can be assuredly met.

Description

Technical field [0001] The invention relates to the field of mechanical engineering, in particular to loading and unloading equipment for hydraulic supports for preparation or relocation of coal mine fully mechanized mining face. Background technique [0002] With the rapid improvement of comprehensive mechanized coal mining technology, the speed of fully mechanized mining is increasing. Objectively, it is required that the preparation and relocation of fully mechanized mining faces must meet production needs, reduce costs, shorten preparation or relocation time, and ensure normal comprehensive coal mining. The connection of mining and production. At present, the most primitive method has been used for the relocation of the hydraulic support in the fully mechanized mining face, that is, digging a large-area loading point at the end of the cutting lane in the fully mechanized mining face, with a radius of 8 to 12 meters. Drive the anchor rod on the top plate, hang the fixed ...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the problems of large hidden dangers of safety accidents, low efficiency, and high investment costs in the operation mode of hydraulic support relocation and loading and unloading in coal mine fully mechanized mining face, the present invention has invented a hydraulic support loading machine for coal mine fully mechanized mining face. The vehicle-machine operation mode is hydraulic cylinder telescopic type; the loading point is set as mobile; at the same time, the support hauling method is changed to short-distance hauling, which can greatly improve the mechanization and work efficiency of hydraulic support relocation, and reduce the labor of operators. Strength, can shorten the time for moving the fully mechanized mining face, thereby ensuring the continuity of coal mine production and the growth requirements of economic benefits
