Frame-type drilling and anchoring robot

Abstract

The invention discloses a frame-type drilling and anchoring robot. The frame-type drilling and anchoring robot comprises a first gang drill mechanism, side wall shield mechanisms, a front net feedingmechanism, a lifting working platform mechanism, a frame-type machine body, a second gang drill mechanism and an anchor net conveying mechanism. When the drilling and anchoring robot reaches the drilling and anchoring position, a supporting anchor net is conveyed to the front net feeding mechanism through the anchor net conveying mechanism; after the side wall shield mechanisms unfold and supportthe net to side wall coal walls and loosen the net, the front net feeding mechanism unfolds the anchor net towards the left side and the right side and then jacks the net to make the net attached to aroof, side wall net pieces and side walls are attached by shields, all drilling machines enter a standby state before the anchor net reaches the position in front of the to-be-supported position, andafter the anchor net reaches the to-be-supported position, drilling and anchoring operation is conducted according to a drilling and anchoring process. The drilling and anchoring robot integrates netconveying, net laying, net jacking, wall protecting, drilling and anchor rod feeding, mechanical efficient and reliable supporting of a roadway is achieved, the labor intensity of workers is reduced,the safety of the workers is guaranteed, and support is provided for further improving the tunneling efficiency.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a frame-type anchor drilling robot. Background technique [0002] At present, coal roadway excavation mainly adopts the alternate operation mode of excavation and anchor separation. According to statistics, in one operation cycle, the support time accounts for 50% to 60% of the total cycle time, and the excavation time accounts for 20% to 25%. Time and mechanical failure time accounted for 10% to 15%, the excavation is fast and the support is slow. Therefore, the balance between support and excavation is the key factor affecting the rapid excavation of coal mines. Therefore, it is of great significance to develop a drilling and anchoring robot that can cooperate with the excavation robot to realize the parallel operation of excavation, drilling and support.

Problems solved by technology

[0003] The bolter is the key equipment for coal mine roadway support. It is mainly divided into single-body bolter, airborne bolter and bolter truck. The single-body bolter requires personnel to operate the bolter for bolting operations. Frequent manual movement results in longer auxiliary operation time, more personnel, low excavation efficiency, high labor intensity, low level of single entry, high risk, poor mechanized anchoring ability, and serial operation with roadheaders is likely to cause anchoring imbalance problem; while the airborne bolter is relatively small in size, it can provide underground workers with a more relaxed working environment, which is convenient for underground workers to produce. It is done manuall
