Multifunctional roadway repair machine and construction method thereof

Abstract

The invention discloses a multifunctional roadway repair machine and a construction method thereof. The multifunctional roadway repair machine comprises a milling and excavation work portion, a multifunctional work arm, a lifting push plate device, a chassis, a control portion and a power assembly. The multifunctional work arm, the control portion and the power assembly are sequentially arranged above the chassis from front to back. The multifunctional work arm is hinged to the chassis. The milling and excavation work portion is hinged to the front end of the multifunctional work arm. The lifting push plate device is hinged to the lower portion of the front end of the chassis. The chassis controls a moving platform through a walking motor to drive the whole machine to walk. The multifunctional work arm controls a work arm rotation drive assembly through various oil cylinders of the work arm to rotate along the moving platform by 90 degrees, and the milling and excavation work portion is controlled to carry out milling, excavation and grooving work on a roadway. The multifunctional roadway repair machine has the roadway omni-directional linear grooving function and is provided witha quick change function execution device, the functions of milling and excavation, crushing and loading are integrated, the multifunctional work arm can rotate left and right by 90 degrees, and mechanical work of rapid and closed roadway connection of the coal mine roadway is achieved.

Description

technical field [0001] The invention relates to a repairing machine for coal mining technical equipment, in particular to a multifunctional roadway repairing machine and a construction method thereof. Background technique [0002] Coal has been one of the main energy sources used by humans since the eighteenth century. Because of its large reserves and easy mining, coal occupies a prominent position in my country's primary energy consumption. In the long run, the proportion of coal in my country's total energy consumption will show a downward trend, but for a long period of time in the future, my country's coal-based energy structure will not undergo major changes. Therefore, whether the coal industry can develop sustainably and healthily is still a major issue for my country's energy security and sustainable economic development. [0003] With the continuous improvement of my country's coal mining technology and equipment, the production capacity of modern coal mines has b...

AI Technical Summary

Problems solved by technology

[0004] At present, the roadway sealing and cutting operations are mainly manual operations, the degree of mechanization is low, the manual operation has high labor intensity and low work efficiency; the cutting is carried out by pneumatic picks, and the function is single, and the coal generated by the cutting cannot be cleaned. Gangster

Although some mechanized roadway repair equipment on the market can complete some roadway repair functions, they still have few functions for the closed roadway cutting operation, and cannot meet the integrated operations of cutting, cleaning, and roadway leveling. Existing equipment The working arm and the milling and digging operation department have less freedom, so it is impossible to carry out all-round cutting and repairing operations on the roadway, and it cannot meet the needs of mechanized operations in closed communication roadways
