Temporary support system integrating automatic net laying, dust removal device, and forward detection functions

Abstract

The invention belongs to the technical field of control and maintenance of underground coal mine roofs, particularly relates to a temporary supporting system integrating functions of automatic lapping, a dust removal device and forward exploration, and solves the problems that an existing underground coal mine temporary supporting system cannot achieve automatic lapping and dust removal, digging and anchoring cannot be synchronously operated, and zero-empty-roof-distance cannot be achieved. The temporary supporting system comprises a temporary supporting mechanism, the temporary supporting mechanism is provided with an automatic lapping mechanism used for storage, conveying and hanging an anchor net, the front end of the temporary supporting system is provided with a self-adaptive top plate adjusting structure, and a closed air guide channel is arranged in the temporary supporting mechanism. An automatic lapping device is arranged, so that storage, conveying and automatic hanging of the anchor net are achieved. A traditional manual net delivery and net linking method is replaced, the labor intensity of workers is reduced, the automation degree of the system is improved, and the development trend of replacing workers through mechanical technology and reducing workers through automation of coal mine equipment is met.

Description

technical field [0001] The invention belongs to the technical field of roof control and maintenance in coal mines, in particular to a temporary support system integrating automatic net laying, dust removal device and forward detection functions. Background technique [0002] Temporary support technology has always been one of the research contents of coal mine roadway support theory and technology. At present, there are three types of temporary advance support commonly used in coal mine underground excavation working faces in my country: one is the temporary support of hanging ring penetrating pipe type front probe beam The second is the airborne temporary support device of the roadheader; the third is the support method of multi-row single hydraulic props plus high-strength I-beam beams. These methods alleviate the pressure of the head-on support of the excavation working face to a certain extent, and improve the support condition of the working face. [0003] But in actual...

AI Technical Summary

Problems solved by technology

[0008] The present invention solves the problems of the existing underground temporary support of coal mines, such as the inability to realize automatic net laying and dust removal, the synchronous operation of digging and anchoring, and the inability to realize zero-empty head distance, etc., resulting in low excavation efficiency, high dust concentration of working flour, and low safety factor of the system To solve the problem, provide a temporary support system integrating automatic net laying, dust removal device and forward detection function
