Abstract

The invention discloses a drilling type coal winning machine for large-dip-angle coal seams. The drilling type coal winning machine comprises a main machine, a drilling tool assembly, a regulating chassis and large-dip-angle regulating mechanisms, wherein the main machine comprises a main frame, and a lower fixed pin row is arranged at the lower part of the main frame; the regulating chassis is mounted at the lower part of the main frame and comprises a chassis frame, the chassis frame is hinged with the main frame, and an upper fixed pin row hole matched with the lower fixed pin row is formed in the upper part of the chassis frame; the large-dip-angle regulating mechanisms are mounted at the left side and the right side of the main frame and have the same structure, each side comprises two dip-regulating oil cylinders which are vertically arranged front and back side by side, and the two dip-regulating oil cylinders are respectively a front dip-regulating oil cylinder and a rear dip-adjusting oil cylinder; fixed rods of each dip-regulating oil cylinder are fixed on two sides of the main frame, and telescopic rods of each dip-regulating oil cylinder are fixed on landing legs at the lower part the dip-regulating oil cylinder. The height of the dip-regulating oil cylinders is regulated to change an included angle of the complete machine and the ground until the included angle is consistent with the dip angle of coal seams, and then the lower fixed pin row is inserted into the upper fixed pin row hole for fixing. The drilling type coal winning machine has a simple and ingenious structure and can realize mechanical mining for the large-dip-angle coal seams.

Description

technical field [0001] The invention relates to a mining machine, in particular to a drilling type coal mining machine suitable for coal seams with large dip angles. Background technique [0002] At present, there are no very effective methods and equipment for the mining of high-inclination coal seams. It is generally difficult to mechanize coal mining in high-inclination coal seams with an inclination angle of more than 55°. The commonly used methods are pseudo-inclined longwall coal mining method and pseudo-inclined flexible cover support. The coal mining method adopts segmental blasting coal mining, which cannot implement real-time roof support. It has extremely strict requirements on the roof and floor conditions of large-inclination coal seams, otherwise it will cause disasters such as collapse and roof fall, and the risk factor is large and the labor intensity of workers is high. , the environment is highly polluted. Contents of the invention [0003] Technical pro...
