Description

Quick butt joint device and anchor rod working arm Technical Field The invention relates to the technical field of anchor bolt supporting operation, in particular to a quick butt joint device and an anchor bolt working arm. Background In the anchor bolt supporting operation, the anchor bolt is installed by taking a lifting hanging basket as a main part and a small amount of simple welding threaded connecting rods to realize semi-mechanized construction operation, the water expansion anchor bolt is a hydraulic expansion anchor bolt, in the current construction process, the water expansion anchor bolt is manually inserted into an anchor bolt hole in a supporting area, then a handheld anchor bolt connecting device is in butt joint with the tail end of the water expansion anchor bolt, the anchor bolt connecting device is connected with a high-pressure water pump station, the water expansion anchor bolt is inflated with high-pressure water to be pressurized, the handheld connecting device is pulled out after the high-pressure water is released to complete the water expansion anchor bolt anchoring operation, at least the following problems of weak rock wall in the area needing anchoring supporting, potential safety hazards exist in the operation of the anchoring area due to manpower, the risk of rock wall falling or even sliding collapse due to the water expansion in the water filling and pressurizing process of the water expansion anchor bolt, the water expansion anchor bolt and the handheld anchor bolt connecting device need to be carried even, lifting and supporting of a platform are needed to be carried, working procedures are complicated, and labor intensity is high, and the construction efficiency is low, the anchor bolt is required to be connected with the water expansion anchor bolt is not needed to be inflated with the water expansion device after the water expansion is inflated by the high-pressure expansion anchor bolt, and the water expansion device is enabled to be filled with the water expansion device after the water expansion is in the water expansion expanding and is filled with the water expansion device.
