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 invention provides a segmented self-propelled heading face fore support, belongs to the technical field of coal mine tunnel supporting equipment, and aims at providing a device capable of following a heading machine to carry out safe and efficient supporting. According to the segmented self-propelled heading face fore support in the technical scheme, an operating table is arranged on the top of a rack, multiple top beam vertical columns for supporting a top beam are arranged on the two sides of the top of the rack at intervals, a connecting beam is arranged between every two opposite top beam vertical columns on the two sides of the rack, a hydraulic oil tank and a motor are arranged on the connecting beam close to the position above the operating table, a first walking part and a second walking part are symmetrically arranged at the bottom of the rack and are the same in structure, and multiple lower supporting oil cylinders are symmetrically arranged at the two ends of the bottom of the rack. The fore support is applied to heading face supporting.

Description

technical field [0001] The utility model relates to a segmented self-excavating face advance support, 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 the empty roof area to erect t...
