AI Technical Summary

Benefits of technology

The bottom plate anchor rod drilling and stabilization device described in the patent has several technical effects. Firstly, it eliminates the need for wooden pillars or reverse air legs to support the roof of the roadway during drilling. This is achieved by using the top and bottom positioning support hydraulic cylinders to directly act on the roof and floor of the roadway, providing stable support without the need for additional support structures. Secondly, the device is equipped with guiding and positioning mechanisms, allowing for drilling in multiple rows or columns of holes without the need for repositioning. This improves efficiency and reduces the time required for drilling and bolt installation. Overall, the device has a simple structure, easy operation, and high installation efficiency. It is particularly suitable for rapid roadway formation and the installation of bolts to support the bottom heave of the roadway.

Problems solved by technology

This patented technical problem addressed in the patents relates to improving the stability and reliability of supporting roads when subjected to severe environmental changes like water intrusion (heavy rain) on top level surfaces caused by heavy loading and tunneling movements near railway lines. Existing solutions involve adding extra layers of concrete over the entire area where tunnel walls meet, reducing their thickness while still providing adequate support against subsidence. These techniques require significant amounts of materials and may result in damage to underlying structures.

Abstract

The invention discloses a base plate anchor rod hole-drilling stabilizing device. The base plate anchor rod hole-drilling stabilizing device comprises a chassis (1), working parts (2), an upper frame (3) and device positioning components (4), wherein the upper frame is fixedly mounted on the chassis; the working parts are mounted on the chassis and comprise a body (21), a front-back guiding mechanism (22), a front-back positioning mechanism (23), a left-right guiding mechanism (24), a left-right positioning mechanism (25), a drilling machine mounting frame (26) and a drilling machine (27); and the device positioning components comprise a top positioning supporting hydraulic cylinder (41), a bottom positioning supporting hydraulic cylinder (42) and a control valve group (43), and the control valve group is connected with the top positioning supporting hydraulic cylinder and the bottom positioning supporting hydraulic cylinder. The base plate anchor rod hole-drilling stabilizing device has a simple structure, and can implement fast hole drilling operations on a roadway base plate on the premise of providing a reverse supporting force in a hole drilling process, thereby integrally improving the mounting speed of an anchor rod and meeting the requirement of fast forming a roadway.
