Net laying material transportation system for net laying mining of working face

Abstract

The invention provides a net laying material transportation system for net laying mining of a working face. The net laying material transportation system for the net laying mining of the working faceis mainly composed of intermediate net laying supports, transition net laying supports A, a transition net laying support B, an end head support, an air return roadway advancing support, a traction device, drag reduction devices, a steering device, a traction rope and a rope returning device. Closed design is adopted for the rear operation space of a full-working-face net laying support, so that asufficient and safe net laying operation space is formed; the optimized working face overall equipment selection matching type is characterized in that a smooth L-shaped net transportation channel isformed in the working face; a net transportation device is organically connected with a working face support and automatically moves forwards along with the front movement of the working face support; the traction device is mainly composed of a motor, a winding drum device, a base, a frequency converter and the like; each drag reduction device is mainly composed of a connector, a support and a roller; and the steering device mainly consists of a vertical roller and a connecting seat. According to the working face net laying material transportation system, the labor intensity of workers is obviously reduced, and the transportation efficiency of net laying materials is greatly improved.

Description

technical field [0001] The invention relates to a net-laying material transportation system on a net-laying mining working face, which belongs to the field of mining machinery. Background technique [0002] The net laying process of net laying mining is mainly composed of three parts: transport net, exhibition net and networking. Because the working space of the coal mining face is very limited, it is very difficult to transport materials on the working face, so the efficiency of net laying mining depends largely on the efficiency of net transport, and the net laying material used in the traditional net laying process is made of metal mesh Mainly, because of its high quality and poor bending performance after being rolled, the transportation of mesh materials on the working surface mainly depends on manual handling, which is not only labor-intensive for workers, but also low in efficiency. [0003] In recent years, with the continuous development of the production technolog...
