Coal mining system capable of automatically assembling and disassembling drill rod groups

Abstract

The invention discloses a coal mining system capable of automatically assembling and disassembling drill rod groups. The coal mining system comprises a twist drill type coal cutter and an automatic drill rod group assembling and disassembling platform, wherein the automatic drill rod group assembling and disassembling platform comprises a bottom plate, a sliding table, a side slip driving device and a drill rod group positioning component; the bottom plate is fixedly arranged on a main engine frame of the twist drill type coal cutter; the sliding table is connected to the bottom plate in a sliding mode with a single degree of freedom and is driven to slide in a reciprocating mode through the side slip driving device; the drill rod group positioning component is arranged on the sliding table; after a drill rod group is positioned on the automatic drill rod group assembling and disassembling platform, the drill rod group can be conveyed between a main engine spindle of the twist drill type coal cutter and a connected drill rod group, and a main engine is controlled to push, so that the assembly of the drill rod group can be finished; the sliding table can return to be in an original position after the drill rod group is assembled, and then a next drill rod group is mounted. The drill rod group can be disassembled through reverse execution, the labor intensity of workers can be reduced, and the drill rod groups can be accurately positioned, so that the process of assembling and disassembling drill rods is smooth, the time consumption is saved, and the coal mining efficiency is improved.

Description

technical field [0001] The invention relates to a coal mining system, in particular to a coal mining system capable of automatically loading and unloading drill pipe groups. Background technique [0002] my country is a country with large coal production and consumption. With economic growth, the demand for coal is also rising. According to the division of coal seam thickness in my country, the thickness of 18 ~ 113m belongs to thin coal seam, and the thickness of less than 18m belongs to extremely thin coal seam. The reserves of thin and extremely thin coal seams are large in my country, and the proportion of thin coal seam reserves in state-owned coal mines alone accounts for about 20%. Large, widely distributed, and locally concentrated. With the decreasing reserves of medium-thick coal seams, the mining of thin and extremely thin coal seams is particularly important. The efficiency is low, so the dependence on mining equipment and technology is greater. The auger shearer...

Problems solved by technology

According to the division of coal seam thickness in my country, the thickness of 18 ~ 113m belongs to thin coal seam, and the thickness of less than 18m belongs to extremely thin coal seam. The reserves of thin and extremely thin coal seams are large in my country, and the proportion of thin coal seam reserves in state-owned coal mines alone accounts for about 20%. Large, widely distributed, and locally concentrated. With the decreasing reserves of medium-thick coal seams, the mining of thin and extremely thin coal seams is particularly important. Low efficiency and therefore greater reliance on mining equipment and technology

The auger shearer is a coal mining equipment that can mine thin and extremely thin coal seams and improve the recovery rate of coal resources. It can realize unmanned working face mining and improve the working environment of workers. Shearers generally use monorail crane clamping and manual positioning to load and unload drill pipes, which not only has a high labor intensity for workers and difficult positioning of drill pipes, but also greatly limits coal mining efficiency, resulting in slow mining of thin and extremely thin coal seams. The problem of low internal production
