An Intelligent Pneumatic Outrigger Vibratory Roof Bolter That Can Identify the Loose 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 vibratory rod bolter capable of identifying the loosening range of surrounding rock. Background technique [0002] In drilling operations, rock bolters are usually used for drilling operations in the surrounding rock of coal mine roadways. The anchor drilling rig can not only perform anchor drilling, but also stir the anchor resin anchoring agent. At the same time, it can also realize the installation and tightening of the anchor nut and apply pre-tightening force to the anchor. Most of the rock bolt rigs are composed of air leg parts, air motors, transmissions, control arms and other components to realize the core functions of the rock bolt rig such as support, power source, driving the drill pipe to rotate, rig control and jacking. [0003] Conventional rock bolt rigs only have the functions of rotation and feed. In actual engineering, ...

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.
