Reinforced supporting device for roadway

Abstract

The invention discloses a reinforced supporting device for a roadway, and belongs to the field of roadway supporting. The reinforced supporting device comprises the roadway and a base, wherein the base is located in the roadway; a reversed loader is installed in the middle of the upper surface of the base; through holes are symmetrically formed in the base; base fixing equipment is movably arranged in the through holes; sleeves are symmetrically welded to the upper surface of the base; hydraulic cylinders are symmetrically installed on the side walls, away from each other, of the two sleeves;the same vertically-arranged supporting side plate is fixed to one of the ends of piston rods of the two hydraulic cylinders; screws are rotationally installed in the sleeves; first bevel gears are installed on the screws; and first motors are installed on one side walls of the sleeves. The reinforced supporting device is novel in design, firm in structure, capable of stably supporting the top andthe two sides of the roadway, high in safety, capable of adapting to the changeable roadway environment and convenient to use; the base can drive a supporting column structure to move, manual disassembling, assembling and carrying are not needed, the labor intensity is reduced, and the reinforced supporting device is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of roadway support, and in particular relates to a reinforced support device for roadways. Background technique [0002] Supporting the transportation lane of the fully mechanized mining face is a prerequisite for ensuring the normal operation and ventilation of the working face. Due to the complex geological conditions of the roadway, the mining of the working face may cause large-scale collapse of the roof of the roadway, especially the transportation roadway at the variable slope section equipped with a loader, which often breaks due to insufficient support strength, affecting coal mining and transportation. [0003] The transfer machine is an important intermediate transfer device in the fully mechanized mining face. It is used to transfer the coal transported by the scraper conveyor on the working face to the belt conveyor. The transfer machine can move as a whole with the advancement of the fully mecha...

AI Technical Summary

Problems solved by technology

When the transfer machine moves, the hydraulic support should also move accordingly, which requires multiple operators to cooperate with each other to release the pressure of each hydraulic column, separate the hydraulic column from the top beam, and manually carry the hydraulic column and top beam to the corresponding position Then assemble and repeat the operation many times, which not only increases the workload of the operator, but also affects the production efficiency

Moreover, in the process of installing and dismantling the hydraulic support, the operator works under the support, once the coal falls from the roof, it will cause personal injury
