Coal mining machine supporting device

Abstract

The invention relates to the technical field of coal mining machines, in particular to a coal mining machine supporting device. The coal mining machine supporting device comprises a bottom plate, a plurality of rolling wheels are fixedly connected with the bottom end of the bottom plate, rails are arranged at the bottom ends of the rolling wheels, a first sliding groove is formed in the left sideof the interior of the bottom plate, a first sliding plate is slidably arranged in the first sliding groove, the bottom end of the first sliding groove is evenly and fixedly connected with a pluralityof first compression springs, and the top ends of the first compression springs make contact with the bottom end of the first sliding plate. According to the coal mining machine supporting device, acoal mining vehicle can be in a horizontal state, the coal mining vehicle is effectively prevented from tilting and rollover, the coal mining vehicle is prevented from moving during working, the stability of the coal mining vehicle during working is improved, a second compression spring and a buffer spring play a role in buffering a brake block and a brake plate in the transverse direction and thelongitudinal direction, acting force generated when the brake plate makes contact with the rails can be relieved, rail abrasion damage caused by sudden contact of the brake plate and the rails is prevented, the service life of the rails is prolonged, and the use practicability of the coal mining machine supporting device is improved.

Description

technical field [0001] The invention relates to the technical field of coal shearers, in particular to a support device for coal shearers. Background technique [0002] Shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor and improve safety, and achieve the purpose of high output, high efficiency and low consumption. [0003] Patent Publication No. CN109915135A discloses a support device for a coal mining machine for coal mine collection, including: a support portion, a limit rod and a pressure plate, the limit rods are more than two and fixed on the top of the support portion; There is a through hole, and the pressure plate is sleeved on the limit rod through the through hole; the top end of the support part and the pressure plate have mutually repelling magnetic parts to make the pressure plate suspend. The support device in the invention has good damping effect,...

Problems solved by technology

[0004] However, coal mining is carried out in the mine. Due to the uneven ground in the mine, the heights of the two tracks laid by the shearer are different. When the height difference between the two tracks is large, the shearer may roll over. Dangerous, the stability of the shearer is poor during coal mining, and the shearer sometimes slips during coal mining
