Description

Technical Field

[0001] The present invention relates to the field of coal mining support, and in particular to an advanced hydraulic support auxiliary self-moving device and a process flow suitable for a coal mining working face, which can significantly improve the linearity and automation level of the advanced hydraulic support movement. Background Art

[0002] my country's "Coal Mine Safety Regulations" (2022 edition) clearly stipulates that support must be strengthened within the influence range of the advance pressure at the connection between all safety exits and tunnels of the coal mining face, and the length of the tunnel with enhanced support shall not be less than 20m. In order to improve the efficiency of advance support of the working face and reduce the labor intensity of workers, advance hydraulic supports are currently mainly used to support the advance support area of ​​the coal mining face. According to the mining process settings, the advance hydraulic supports need to move with the mining of the working face. Generally, the front and rear frames are used as support points for pulling and moving. However, since the advance support area generally has a certain inclination angle and pitch angle, the advance hydraulic supports are very prone to tilting, falling and other safety accidents during movement.

[0003] The advanced support area of ​​the coal mining face generally needs to be equipped with advanced hydraulic supports, transfer machines, crushers and other equipment. Figure 1-2 As shown, the tunnel advance support area is very crowded. In order to prevent the advance hydraulic support from falling over, tilting and other accidents, the advance hydraulic supports on the left and right sides are generally connected by a crossbeam or a horizontal jack. However, since the advance support area has inclination and pitch angles, connecting the advance hydraulic supports on the left and right sides only improves the stability of the advance hydraulic support. Since the advance hydraulic support lacks directional traction during the pulling and moving process, and is affected by the inclination angle and pitch angle of the tunnel, the straightness of the advance hydraulic support during the moving process is difficult to control. Traditional advance hydraulic supports still require manual orientation, and the hydraulic support moving process is difficult to automate. There are problems such as difficulty in ensuring the straightness of pulling and moving, high labor intensity, easy to cause personal injuries, and difficulty in automation. The advance support of the coal mining face has become the core technical bottleneck restricting the safe, efficient and intelligent mining of the working face. After searching, there are no relevant technologies and equipment at home and abroad to improve the straightness level and automation level of the advance hydraulic moving frame. The above problems need to be solved urgently. Summary of the invention
