Mine car structure temporarily increasable in transport volume

Abstract

The invention provides a mine car structure temporarily increasable in transport volume. The mine car structure comprises a main tank, main tank supporting shafts and a first gear. A second supportingframe is fixedly mounted on one side of the top of a main supporting plate. By arrangement of the first gear and a second gear, convenience in use is benefited. When coal in the main tank needs to bepoured out, a main tank stabilizing bolt is screwed off, the second gear is driven to rotate by a rocker and a rocker rotating shaft so as to drive the first gear and the main tank supporting shaftsto rotate, and then the coal in the main tank is poured out; by the second gear driving the first gear to rotate, labor saving is realized. When a small quantity of coal is left and cannot be loaded completely, extension retaining plate positioning bolts are all screwed off, four extension retaining plates are pulled up, and then the extension retaining plate positioning bolts are mounted again byscrewing to fix the extension retaining plates, so that mine car capacity can be effectively increased, and convenience in use is achieved.

Description

technical field [0001] The invention belongs to the technical field of coal mine transportation and mine car structure, and in particular relates to a mine car structure that can temporarily increase the transport volume. Background technique [0002] A coal mine refers to a place rich in coal resources, and usually refers to a factory that produces coal by underground or open-pit mining. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the ground surface is very short, it is generally selected to directly strip the surface soil layer to excavate the coal. This is an open-pit coal mine. At present, in the existing coal mine mining process, it is often necessary to use a dump truck to transport the mined coal mine. [0003] For example, the patent application No. 201510304632.1 discloses a tipping mine car used in co...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a mine car structure that can temporarily increase the transport volume, so as to solve the problem that when the existing mine car needs to pour out the coal in the mine car box, workers often need workers to remove the box on the mine car. The body is rotated so that the top opening of the box body is inclined to the side of the mine car, so that the coal in the box body can be poured out, but because the weight of the box body is heavy, it is more laborious for workers to rotate, and the current Mining carts are all of fixed capacity. When there is a small amount of coal, it needs to be transported repeatedly, and it cannot be transported out at one time, which is inconvenient to use.
