Underground horizontal belt extension conveyor for coal mine

Abstract

The invention provides an underground horizontal belt extension conveyor for a coal mine. The conveyor comprises a conveyance belt 1, rollers 2, a belt conveyor support 3, riding wheels 4, a drum 5, 8-12 supporting cars 6, a drag supporting car 7 and the like. In the drawing, 8 refers to an underground loader for a coal mine, and 9 refers to a mine car. The tail end of the conveyance belt 1 extends to the first of mine cars behind an electric locomotive; the width of the belt conveyor support 3 is the same as the width of each mine car; and the riding wheels 4 are symmetrically distributed at the two sides and are respectively clamped on the edges at the two sides of each mine car, so that the conveyance belt 1 operates stably to carry out conveyance. The speed range of the electric locomotive can be estimated more accurately according to the capacity of each mine car and the operating rate of the conveyance belt 1. The conveyor has the characteristics of high loading efficiency and compact structure, and is simple to operate and easy to design and manufacture.

Description

technical field [0001] The invention relates to a belt horizontal extension loader in a coal mine, which belongs to the category of mining machinery. Background technique [0002] Coal is the main energy source in our country, and it will still be the main energy source in our country for a long time to come. It is a reality and an inevitable choice for the development of my country's energy industry to give full play to the advantages of coal resources, based on coal and domestically, so the safe and efficient mining of coal is of great significance. [0003] At present, the loading method adopted by most coal mines in China is that the loader loads minerals into the mine car, and then transports them out of the mine. Car shipped out. The problem it brings is that the underground roadway is required to be widened, and the transportation efficiency is reduced, thereby increasing the transportation cost and labor intensity. Therefore, it is necessary to improve it to reduc...

Problems solved by technology

The bucket-type reloading train uses a hydraulic system to hold up the bucket trucks in the order of the mine cars and load them sequentially from front to back. Although this invention increases the loading efficiency to a certain extent, it does not fundamentally solve the continuity of the loading system; "self-made "Bridge-type reloading belt conveyor" uses a gantry bracket to suspend the belt conveyor above the mine car, and continuously loads six mine cars at one time. Although the loading efficiency can be increased to 3 to 6 times the original in theory, there is still no solution. At the same time, the system has a huge structure and is difficult to move. It is difficult to guarantee its reliable operation in the harsh environment of the mine; the belt (scraper) reloading train is transformed from a bottom unloading or side unloading mine car. , the transformation cost is high, and when loading, multiple belt (scraper) machines above the train need to be transposed back and forth in sequence in adjacent mine workshops, which affects the loading efficiency and continuity. It increases the load on the mine car and restricts other uses of the mine car
