Tunnel repair machine for coal mine

Abstract

The invention discloses a tunnel repair machine for a coal mine, and belongs to the field of coal mining. The tunnel repair machine comprises a vehicle body part and an execution mechanism, wherein the vehicle body part comprises a travelling device and a vehicle frame installed above the travelling device; the execution mechanism comprises a large arm, a small arm and a bucket; one end of the large arm is installed at the front end of the vehicle frame through a lifting mechanism, the large arm is connected with the small arm, and the bucket is installed at the other end of the small arm; the lifting mechanism comprises two guide rails vertically installed at the front end of the vehicle frame, and a slide block; the slide block is matched with U-shaped grooves in the guide rails through two guide bars in a vertical direction, which are arranged at one side of the slide block; and the slide block is connected with the vehicle frame through a vertically-installed hydraulic oil cylinder, and the large arm is installed at one side away from the guide rails, of the slide block, through a middle mechanism. The tunnel repair machine disclosed by the invention has the advantages of being wide in application range, high in working efficiency, and the like.

Description

technical field [0001] The invention relates to an excavator, in particular to a roadway maintenance machine for coal mines, which belongs to the field of coal mining. Background technique [0002] The roadway repair machine is widely used in the field of coal mining. It is mainly used for excavating and loading the roof, floor and side walls of the coal roadway, semi-coal rock roadway and full rock roadway. It can also be used for large rocks and coal blocks. for crushing. The functions of the existing roadway maintenance machines are basically similar to those of construction excavators. The excavating arm can only move in a single direction, and cannot perform actions such as oblique digging, digging, swinging, and rotation. When excavating and crushing operations in the area, the operator needs to constantly adjust the angle of the fuselage to ensure that the excavating arm can face the work area at any time. The structure of the traditional roadway maintenance machine...

Problems solved by technology

The functions of the existing roadway maintenance machines are basically similar to those of construction excavators. The excavating arm can only move in a single direction, and cannot perform actions such as oblique digging, digging, swinging, and rotation. When excavating and crushing operations in the area, the operator needs to constantly adjust the angle of the fuselage to ensure that the excavating arm can face the work area at any time.

The structure of the traditional roadway maintenance machine leads to low working efficiency, inconvenient operation, and even inability to perform normal operations on some areas in the coal mine roadway, such as the bottom of the belt of the coal mine conveyor. For such areas, workers can only manually complete the daily work. Cleaning up is a huge waste of human resources
