Problems solved by technology

Many downhole bolting uses single-body bolting rigs. These rigs generally have problems such as low automation level, low anchoring efficiency, high labor intensity, harsh working environment, and poor safety.
A better solution is to use a rock bolter instead of a single rocker to improve the efficiency of anchoring and protection, enhance the safety of anchoring and realize cross-operation with the roadheader, but due to the limitation of the tunneling process, the bolter When bolting, the bolter is in an area without anchoring, and there is also a safety risk of no support. Therefore, it is necessary to provide a temporary support device on the bolter for temporary support of the roadway roof. To ensure the safety of the rock bolter, however, the traditional temporary support device for the rock bolt has many problems such as low automation, frequent operation, poor adaptability to the roof of the roadway, heavy mechanism, and small supporting force, which makes the temporary support The effect of the protective device is not ideal, and the safety of the working area of ​​the rock bolter operator cannot be well guaranteed

Abstract

The invention relates to coal mining equipment and provides a self-adaptive temporary supporting device for an anchor rod drill rig. The self-adaptive temporary supporting device for the anchor rod drill rig comprises a telescopic mechanism and a supporting mechanism arranged on the end part of the telescopic mechanism; one end of the telescopic mechanism is connected with the anchor rod drill rigand the end part of the other end of the telescopic mechanism is connected with the supporting mechanism; the supporting mechanism comprises a cross beam sleeve and supporting cross beams; the crossbeam sleeve is connected with the telescopic mechanism; the supporting cross beams are arranged at the two ends of the cross beam sleeve and are fit with the operation top surface of the anchor rod drill rig; a lifting oil cylinder for providing telescopic power is arranged in the telescopic mechanism; and a swing oil cylinder is arranged at the connection position of the telescopic mechanism andthe anchor rod drill rig. A tunnel top plate is automatically supported by a temporary supporting device through an automatic control system and according to different tunnel top plate conditions, sothat safety of anchor rod drill rig operation personnel is effectively guaranteed.

Description

technical field [0001] The invention belongs to rock bolt support equipment, in particular to an adaptive temporary support device for a rock bolt drilling vehicle. Background technique [0002] At present, most coal mine roadway excavation in my country adopts the form of bolt support. Many downhole bolting uses single-body bolting rigs. These drilling rigs generally have problems such as low automation level, low anchoring efficiency, high labor intensity, harsh working environment, and poor safety. A better solution is to use a rock bolter instead of a single rocker to improve the efficiency of anchoring and protection, enhance the safety of anchoring and realize cross-operation with the roadheader, but due to the limitation of the tunneling process, the bolter When bolting, the bolter is in an area without anchoring, and there is also a safety risk of no support. Therefore, it is necessary to provide a temporary support device on the bolter for temporary support of the ...
