Abstract

The invention discloses a multifunctional tunnel repairing machine which comprises a main rack, a working platform, a working arm, a shoveling plate and a walking crawler belt, wherein the working platform is arranged above the main rack, and the working arm is hinged in front of the main rack and driven to swing left and right through a swing oil cylinder; the shoveling plate is hinged at the front end in front of the main rack, and a hydraulic oil cylinder used for driving the shoveling plate to move up and down is arranged between the shoveling plate and the main rack; the walking crawler belt is arranged under the main rack and drives the main rack to go forward. The working arm can swing left and right and rotate for 360 degrees, and a tail end actuating mechanism can reach each working face at a flexible azimuth angle, so that the working dead angle is avoided, and the working faces are large. A gear rack rotating reducer ensures torque transmission and meanwhile can bear the bending moment brought by the tail end actuating mechanism during the working process, and the service life is prolonged. The width and the height of the working platform can be adjusted, and the height flexibility is strong. The multifunctional tunnel repairing machine has the advantages of being flexible and convenient in integral operation and safe and reliable in structure, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of roadway repairing equipment, and in particular relates to a multifunctional roadway repairing machine. Background technique [0002] The multi-functional roadway repair machine is an important loading equipment in coal mines. It is mainly used in the roadway repair working face of broken surrounding rock, and undertakes the roadway repair task. In the existing construction technology, the removal of broken surrounding rock and the replacement and removal of anchor rods and anchor nets are usually done manually. In actual construction, due to the limitation of rock hardness and the degree of brokenness of the surrounding rock of the roof, manual construction increases the labor intensity of workers and reduces the excavation efficiency; due to the need for manual crushing and slag removal on unsupported sections, it also increases the construction cost. risk factor. Contents of the invention [0003] In view of ...
