A frame type anchor drilling robot

Abstract

The invention discloses a frame type anchor drilling robot, which comprises a first row of drilling mechanism, a side shield mechanism, a front access mechanism, a lifting work platform mechanism, a frame type body, a second row of drilling mechanism and an anchor net transport mechanism; When the anchor drilling robot reaches the anchor drilling position, it transmits the supporting anchor net to the front netting mechanism through the anchor net transportation mechanism, and the side shield mechanism expands the support net to the side coal wall and loosens the net. After the anchor net is unfolded sideways, the upper net is attached to the top plate, and the shield is used to attach the side mesh to the side. When the anchor net reaches the position to be supported, all drilling rigs enter the standby state, and when the anchor net reaches the position to be supported After being in place, carry out drilling and anchoring operations according to the drilling and anchoring process. The anchor drilling robot of the present invention integrates net transportation, net laying, top net, side protection, drilling, and bolting into one body, realizes efficient and reliable support of roadway mechanization, reduces the labor intensity of staff, and ensures the safety of workers , to provide support for further improving the efficiency of excavation.

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. [0003] The bolter is the key equipment for coal mine roadway support. It is mainly divided into single-body bolter, airborne bolter...

AI Technical Summary

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 manually, especially in the aspect of net laying. The traditional manual net laying method is adopted, and the metal net is manually transported to the net laying site, and the net laying operation is performed manually; although the bolter can realize high-efficiency and fully mechanized anchoring However, it is generally used in conjunction with roadway excavation equipment to carry out supporting operations in an alternate operation mode, which cannot guarantee efficient excavation efficiency

[0004] To sum up, the current drilling and anchoring support device uses a large number of manual assistance to complete the support, in which manual assistance takes up most of the support work time, and the equipment is not comprehensive enough
