Rapid installation, detection and transformation method for anchor rods and anchor cables in large-clear-height roadway

Abstract

The invention provides a large-clear-height roadway anchor rod and anchor cable rapid installation and detection transformation method, and belongs to the technical field of anchor rod and anchor cable installation. Comprising the following steps that S1, a lengthened stirrer is installed, specifically, the lengthened stirrer is installed on an anchor rod or an anchor cable through a welding mechanism; s2, manufacturing an anchor rod or anchor cable rapid glue filling sleeve, wherein the rapid glue filling sleeve is manufactured by machining a stainless steel pipe with the diameter being 31.8 mm and the length being 1200 mm; s3, manufacturing of a cannon plug, wherein the cannon plug is made of plastic with the diameter of an upper round check ring being 20 mm and the diameter of a lower four-supporting claw being 42 mm; s4, anchor rods or anchor cables are installed; s5, processing an anchor rod or anchor cable detection servomotor; and S6, detecting the anchor rod or the anchor cable: when the initial anchor force is detected, sleeving one end of a detection servomotor on the to-be-detected anchor rod or anchor cable, sleeving the other end of the detection servomotor with a torque wrench, and supporting the detection servomotor by hands for detection. When the monorail crane fixing anchor rod is installed on the rear road, more time is saved by adopting the anchor rod or anchor cable lengthening stirrer for construction compared with erecting a working platform, and therefore the working efficiency is conveniently improved.

Description

technical field [0001] The invention relates to the technical field of bolt anchor cable installation, in particular to a fast installation, detection and transformation method for an anchor bolt and cable in a roadway with a large clear height. Background technique [0002] At present, due to the continuous improvement of the degree of mechanization in coal mines and the popularization of fully mechanized mining faces, the clear heights of most of the mining roadways are not less than 3.5 meters for the transportation and installation of fully mechanized mining equipment. Reach or exceed 4 meters, and the installation of the rear road transport monorail crane and the anchor cable of the roadway reinforcement support are carried out in the later stage. Since the maximum suitable operating height of the current rock bolt drilling rig is 3.25 meters, a scaffold or working platform must be erected before installing the bolt and anchor cable, otherwise it cannot be installed due...

AI Technical Summary

Problems solved by technology

Setting up scaffolding or working platforms is not only time-consuming and labor-intensive, but there is a greater safety risk in working on them

In addition, the head-on detection of the initial anchor force of the roof bolt needs to be operated on a ladder, which brings great difficulties to the detection work, and there is a great danger in the operation of stepping up.
