Intelligent pneumatic supporting leg type vibrating anchor drilling rig capable of recognizing looseness range of surrounding rock

Abstract

The invention discloses an intelligent pneumatic supporting leg type vibrating anchor drilling rig capable of recognizing the looseness range of surrounding rock. The anchor drilling rig comprises a drill bit, a drill stem, a transmission device, a drill stem pneumatic motor and a telescopic air leg. An operating arm, a pneumatic valve, an air intake pipe, an indicator light and a control button are further arranged on the side face of the anchor drilling rig, wherein the indicator light and the control button are installed on the operating arm. A surrounding rock looseness automatic recognition system receives the current actual drilling rate of the drill bit transmitted by a drilling rate sensor; data of the current position of the drill stem sent by a position sensor are received, and the current drilling depth is obtained through calculation; according to the current actual drilling rate returned by the drilling rate sensor, whether the current position of the drill bit is located in a stable stratum or not is judged, and whether the current drilling depth meets the anchoring depth requirement of an anchor rod or not is judged; if it is judged that the current actual drilling rate detected by the drilling rate sensor is larger than or equal to the standard drilling rate value of the drill bit in the stable surrounding rock and the current drilling depth meets the anchoring depth requirement of the anchor rod, it is judged that the current surrounding rock is stable surrounding rock.

Description

Technical field [0001] The invention relates to the field of drilling equipment, in particular to an intelligent pneumatic outrigger type vibration bolting rig capable of identifying the loosening range of surrounding rock. Background technique [0002] In drilling operations, bolting rigs are usually used to drill the surrounding rock of coal mine tunnels. The bolt drill can not only perform bolt drilling, but also mix the resin anchoring agent of the bolt. At the same time, it can also realize the installation and tightening of the bolt nut and the pre-tightening of the bolt. Most rock bolting rigs are composed of air leg components, pneumatic motors, transmission devices, control arms and other components to realize the core functions of rock bolting rig support, power source, driving drill rod rotation, rig control and jacking. [0003] Conventional bolting rigs only have the functions of rotation and feeding. In actual engineering, these two basic functions are used to drill ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, it is difficult for conventional rock bolters to automatically identify the range of loose surrounding rock and to record the drilling depth automatically and in real time during the drilling process.
