Auxiliary bracket moving device of circular self-moving advance support

Abstract

The invention relates to an auxiliary bracket moving device of a circular self-moving advance support, which solves the problem in the prior art that the high-efficient and safe operation requirement of a wind lane of a fully mechanized coal mining face cannot be met. The auxiliary bracket moving device comprises a conveying device arranged between two hydraulic stand columns of an advance support bracket and is characterized in that the conveying device comprises a combined basal plate, a hydraulic winch, a tapping track, a bracket transporting car and a self-moving device; the combined basal plate is composed of wide and narrow basal plates which are in segmented connection; the hydraulic winch and the tapping track are assembled on the combined basal plate, and the bracket transporting car is assembled on the tapping track and is composed of a sliding base, a lifting hydraulic cylinder, a guide sleeve, a guide rod and a carrier. A traction rope of the hydraulic winch drives the bracket transporting car to move along the tapping track to sequentially transport the dropped advance support bracket through the carrier. The self-moving device drives the combined basal plate and a self-moving slideway to longitudinally move along a roadway. The auxiliary bracket moving device has the advantages of reasonably structural design, stability in bracket movement, convenience in operation and safety in use, can adapts to the actual using demand of the wind lane, and is beneficial to safe and high-efficient production of the coal mining face.

Description

technical field [0001] The invention relates to an auxiliary frame moving device for safety support of a fully mechanized working face roadway, in particular to an auxiliary moving device used in the normal working face mining operation, and is used in the return air trough (wind lane) at the outlet of the working face. The advance section support of the roadway moves forward with the advancement of the mining of the working face, which is a cyclic self-moving auxiliary support moving device for the advance support. It belongs to the field of mining machinery manufacturing and application. Background technique [0002] The safety support of the roadway in the fully mechanized mining face mainly adopts U-shaped steel, I-steel metal brackets, anchor rods, anchor nets and other joint support methods. With the continuous advancement of the coal mining face, the pressure in the leading section of the roadway moves forward, so it is necessary to strengthen the support at the lead...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a cyclic self-moving type advanced support auxiliary moving device, which solves the difficulty in ensuring the walking track of the existing working face wind tunnel advanced support movement mode, repeatedly supporting the roof, cumbersome operation, and slow moving speed. Slow, low operating efficiency and other issues, its structural design is reasonable, the support moves stably, easy to operate, safe to use, and can meet the needs of efficient and safe operation of the wind tunnel, thereby reducing the impact of the wind tunnel advance support operation on the coal mining production of the working face , which is conducive to the further improvement of the production capacity of the coal mining face
