Non-permanent coal mine underground roadway self-walking supporting device

Abstract

The invention provides a non-permanent coal mine underground roadway self-walking supporting device, and belongs to the technical field of coal mine underground supporting equipment, and the non-permanent coal mine underground roadway self-walking supporting device comprises a single-span supporting assembly and a walking assembly; the single-span supporting assembly comprises a top supporting beam, a multi-stage telescopic sleeve, a supporting base and a vertical telescopic mechanism. The top supporting beam is a square beam; the multi-stage telescopic sleeve is composed of a plurality of cylinder bodies which are sequentially connected in a sliding and sleeved mode, the top end of the cylinder body located on the uppermost portion is connected with the bottom face of the top supporting beam, and the bottom end of the cylinder body located on the lowermost portion is connected with the supporting base. The four multi-stage telescopic sleeves are located at the four corners of the top supporting beam correspondingly. The vertical telescopic mechanism is installed in the multi-stage telescopic sleeve and used for driving the multi-stage telescopic sleeve to stretch out and draw back. The walking assembly comprises a vehicle body, a fixed supporting rod connected with the vehicle body and the top supporting beam and walking parts arranged on the two sides of the vehicle body. The device solves the problems that an existing underground support is low in erecting efficiency, low in erecting and carrying speed, high in labor intensity of constructors and poor in supporting stability and safety.

Description

technical field [0001] The invention belongs to the technical field of coal mine underground support equipment, and specifically discloses a non-permanent coal mine underground roadway self-propelled support device. Background technique [0002] During underground mining operations in coal mines, there are clear regulations on roof support during roadway construction, and roadways within 20 meters of the mining area must be strictly supported. During the support construction of the roadway of two troughs (especially the return trough), temporary support methods are initially adopted, including temporary support of the front probe beam and temporary support of the airborne, etc. These methods are poor in construction safety and labor-intensive for construction personnel. Large, low support efficiency and slow speed. Then the advanced support is widely used, including single hydraulic prop, integral advanced support and split advanced support. Among them, the support and with...
