Abstract

The self-propelled advance support following the roadheader 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: follow the self-propelled roadheader For the advanced support, the operating 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 between every two top beam columns opposite to each other on both sides of the frame are set. There is a connecting beam, and a hydraulic oil tank and a motor are arranged on a connecting beam close to the top of the operating platform. The first running part and the second running part are symmetrically arranged at the bottom of the frame, and the first running part and the second running part have the same structure. A plurality of lower supporting oil cylinders are arranged symmetrically at both ends of the bottom of the machine frame, and the invention is applied to the support of the excavation surface.

Description

technical field [0001] A self-propelled advance support following a roadheader 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 the empty roof area to erect the temporary support. Moreove...
