Walking type conveyor cooperating with coal mining machine

Abstract

The invention belongs to the field of coal mining equipment, and discloses a walking type conveyor cooperating with a coal mining machine. The walking type conveyor is formed by movably connecting a first walking type conveyor and a second walking type conveyor, a left steel pipe and a right steel pipe in the first walking type conveyor are arranged on the left side of a first support and the right side of the first support respectively, first groove-shaped supporting rollers are arranged between the inner upper side of the left steel pipe and the inner upper side of the right steel pipe, a first walking device is movably connected with the lower portion of the front end of the first support, and a second walking device is movably connected with the lower portion of the rear end of the first support; the left steel pipe and the right steel pipe in the second walking type conveyor are arranged on the left side of a second support and the right side of the second support respectively, asecond groove-shaped supporting rollers are arranged between the inner upper side of the left steel pipe and the inner upper side of the right steel pipe, a third walking device is movably connected with the lower portion of the rear end of the second support, and the lower part of the front end of the second support is movably connected with the second walking device; and a limiting device is arranged on each of the left side of the first walking device and the right side of the first walking device, the limiting device is arranged on each of the left side of the second walking device and theright side of the second walking device, and the limiting device is arranged on each of the left side of the third walking device and the right side of the third walking device. According to the walking type conveyor cooperating with the coal mining machine, a protection function to cables and optical fibers, an automatic walking function, a walking limit anti-deviation function, a self-protection function and a horizontal transferring function are obtained.

Description

technical field [0001] The invention belongs to the field of coal mining equipment, in particular to a walking conveyor used in conjunction with a coal shearer, and is mainly used for coal mining operations in open-pit coal mines. Background technique [0002] Inner Mongolia is the province with the widest distribution and largest number of open-pit coal mines in the country. There are 253 open-pit coal mines, accounting for 43% of the total 584 coal mines in the region; the approved production capacity is 518.75Mt, accounting for 1176.45Mt of the total approved production capacity of coal mines in the region. 44%. The open-pit coal mines in Inner Mongolia, especially the most concentrated Ordos City, most of the mine fields are irregular in shape and small in size, resulting in a large amount of coal pressure on the sides, and the uneven distribution of this part of the resources makes it difficult to carry out secondary recovery, causing a relatively large impact on resour...

AI Technical Summary

Problems solved by technology

[0004] In the past, the coal flow conveying equipment used in conjunction with the continuous coal mining machine was a belt conveyor. As the coal mining machine moved forward continuously in the coal mining face in the roadway, the length of the belt conveyor behind the coal mining machine was not enough , the belt conveyor needs to be spliced, and the splicing process is time-consuming and laborious; the belt conveyor often deviates in the roadway and needs to be corrected manually, which affects the normal transportation of coal flow; Dragging, affecting coal mining progress, etc.
