Automatic blanking machine pay-off disc of mining anchor cable

Abstract

The invention relates to an automatic blanking machine pay-off disc of a mining anchor cable, and belongs to the technical field of coal mine machinery. The automatic blanking machine pay-off disc ofthe mining anchor cable is characterized in that when an anchor cable blanking operation is carried out, the bundled anchor cables are placed on a rotating disk above a sliding base, a middle shaft penetrates through the center of the anchor cable bundle, after the anchor cable bundle is placed on the sliding base, the sliding base moves downwards under the action of gravity; a spring seat compresses a reset spring, when the sliding base moves downwards, the spring seat pushes connecting rods through hinge mechanisms, and the connecting rods push sliding blocks to move towards the outer side in sliding grooves; and the anchor cable bundle is tightly pressed by baffles under the action of springs, after blanking of the anchor cable is finished, the gravity of the sliding base disappears, and the reset spring drives the sliding base to move upwards. According to the automatic blanking machine pay-off disc, the rotating disc is arranged on the sliding base, the anchor cable bundle placedon the sliding base can be freely rotated through the rotating disc, the blanking speed is increased, meanwhile, double-brake can timely brake the anchor cable bundle, and the accuracy of blanking andcutting of the anchor cable is effectively improved.

Description

Technical field [0001] The invention relates to a pay-off reel of an automatic cable-cutting machine for mining, belonging to the technical field of coal mine machinery. Background technique [0002] With the continuous development of coal technology, underground support technology has also been continuously improved. Bolt and cable support has become the main method of coal mine roadway support. Different roadways and working faces often require different lengths of anchor cables. When leaving the factory, they are all packaged in whole bundles. Therefore, the anchor cable needs to be cut and cut according to the actual size. The anchor cable is unrolled on the ground and then bent and fixed to the well before being deployed and installed. During the anchor cable cutting process , The traction and cutting of the anchor cable are all realized manually, the degree of automation is low, and the risk is high. There are no controllable facilities during the deployment process of the ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem mainly solved by the present invention: in view of the fact that there is no controllable facility in the process of unwinding the anchor cable in the pay-off reel of the existing mining anchor cable automatic cutting machine, the out-of-control phenomenon occurs from time to time, and the whole bundle of anchor cables is easy to loosen, resulting in To solve the problem of inaccurate cutting length of anchor cables, the invention provides a pay-off reel for mining anchor cables automatic unloading machine
