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 the operator enters the empty roof area to erect the temporary support. Moreover, the support effect of this temporary support is not good enough, and the safety is not good. high

Abstract

The advance support of the excavation face that can be synchronously anchored and protected belongs to the technical field of coal mine roadway support equipment. The technical problem to be solved is to provide a device that can follow the roadheader for safe and efficient support. The technical solution adopted: synchronous anchor The advance support of the excavation surface of the protection, the operation table is set on the top of the frame, and a plurality of top beam columns supporting the top beam are arranged at intervals on both sides of the top of the frame, and every two top beam columns standing opposite each other on both sides of the frame There are connecting beams between them, and a hydraulic oil tank and a motor are arranged on a connecting beam close to the top of the operating platform. The internal structure is the same, and a plurality of lower support oil cylinders are symmetrically arranged at both ends of the bottom of the frame, and the invention is applied to the support of the excavation surface.

Description

technical field [0001] The utility model relates to an advance support for a driving face capable of synchronous anchor protection, which belongs to the technical field of coal mine roadway support equipment. 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 operate, and the work efficiency is low. Moreover, there are relatively large safety hazards when the operator enters ...
