Problems solved by technology

This working method requires the exit of the roadheader to operate, and the work efficiency is low. Moreover, there are relatively large safety hazards when operators enter the empty roof area to erect temporary supports. Moreover, most of the existing temporary supports are front probe beams suspended along the direction of the roadway. The roof has been supported and the bolts are extended to the empty roof area, which acts as a roof protection for the roof. The support effect of this temporary support is not good enough, and the safety is not high

Abstract

The invention relates to a synchronous pre-support and anchorage device for follow-up heading machines, belongs to the technical field of fully-mechanized coal mining equipment for coal mines and particularly relates to a device for pre-support and anchorage of a working surface. The pre-support and anchorage device is high in operating efficiency, effective in support and high in safety. According to the technical scheme, a framework is fixedly mounted on two symmetrically arranged travelling mechanisms identical in structure. A lifting anchorage platform and a pre-support platform are fixed on the framework, a lifting frame is arranged on the pre-support platform, beam transport guide rails are mounted on the lifting frame, a cart moving winch and a rail moving winch are mounted on a mounting panel of the pre-support platform, the cart moving winch is connected with a beam transport cart through a steel wire to control the beam transport cart to move on the beam transport guide rails, and the rail moving winch is connected with the beam transport guide rails through a steel wire to control the beam transport guide rails to move on the lifting frame. The synchronous pre-support and anchorage device is applicable to anchorage and pre-support of working surfaces of coal mine tunnels.

Description

technical field [0001] The invention relates to a device for synchronous pre-support and anchor protection following a roadheader, which belongs to the technical field of fully mechanized mining equipment in coal mines, and in particular relates to a device for performing pre-support and anchor protection on a working face. Background technique [0002] At present, rock bolt support is generally used for the support of fully-mechanized tunneling in coal mines in my country, and temporary support must be carried out before the bolt support is carried out. The existing technology is that the roadheader needs to exit after a certain distance in the working face, and then the operator It is necessary to enter the empty roof area to erect temporary supports. After the temporary supports are erected, the anchor protection machine enters the working face that needs anchor protection to perform anchor protection operations. This working method requires the exit of the roadheader to o...
