A kind of flexible support integrated equipment for complex roadway

Abstract

The invention discloses a flexible support integrated equipment for complex roadway, which includes five parts: a walking system, a roof anchor net access system, a side support and a net laying system, an anchoring system, and a roof flexible support and net laying system. . Further, the present invention adopts an integrated flexible support technology to solve the problem of incompatibility between the surrounding rock and the support body in complex roadways, and enhances the stability of the surrounding rock to the greatest extent; a hydraulic damping segmented flexible support mechanism is used to flexibly support the roadway. According to the actual deformation degree of the surrounding rock of the roadway, the anchor net and the roadway can be closely attached; the top plate double-clamping hand-type automatic net laying device, the side double drum type continuous net laying device and the multi-group multi-degree-of-freedom net laying device are adopted. The anchoring system realizes the coordinated support operation, and has the functions of full-section automatic net laying and spatial multi-dimensional synchronous support.

Description

technical field [0001] The invention belongs to the technical field of roadway support, in particular to a flexible support integrated equipment for complex roadways. Background technique [0002] Due to the complex environment of the surrounding rock of the roadway in my country, soft and broken surrounding rock, separation of layers, abnormal development of cracks, etc. generally exist in the roadway, and the stability of the roadway is affected by external complex conditions (such as mining influence, soft surrounding rock, high stress, etc. )Greater impact. The traditional support equipment and support technology (such as bolt and shotcrete support, rigid U-shaped shed support, etc.), although to a certain extent, by virtue of its high strength and high support force characteristics, alleviate the problem of surrounding rock deformation, but There are also obvious flaws: [0003] First, the metal support used in the traditional support technology has an uncoordinated su...

AI Technical Summary

Problems solved by technology

[0003] First, the metal support used in the traditional support technology has an uncoordinated support structure and a single support method, and its high strength and high support force support characteristics prevent the relatively high plasticity in the roadway from being released slowly and effectively. Lead to local stress concentration, local fracture damage or distortion of the metal support, and eventually lead to instability of the surrounding rock

[0004] Second, the roadway roof and side wall rocks in our country often have unevenness and large fluctuations. However, the rigid support beams used in the existing support equipment are difficult to make the anchor net fully fit the uneven roadway surface. As a result, the effective support area of ​​the anchor net is reduced, and the joint support effect of the anchor net and the anchor rod is insufficient.

[0005] Thirdly, the manual net laying and manual anchoring methods currently used in underground mines prolong the interval between the three processes of net laying, support, and anchoring, and the cooperative operation ability between temporary support and permanent support is weak. Further lead to the prolongation of the empty roof time of the roadway, which intensifies the deformation of the surrounding rock
