The movable column 115 is rotatably connected, and the movable column 115 is slidably connected to the support column 114, and the support column 114 is fixedly connected to the slider 113, and the slider 113 is slidably connected to the two slide bars 112, one end of the spring 120 is fixedly connected to the mounting frame 117, and the other end of the spring 120 is fixedly connected to the fixed plate 119, and the fixed plate 119 is fixedly connected to the bayonet 118, and the bayonet 118 is movably connected to the mounting frame 117, and the mounting frame 117 is fixedly connected to the support column 114. The first push rod 105 and the second push rod 107 currently set can move with the movement of the lifting assembly 102, and the arc-shaped bracket 116 continues to play a supporting effect and maintain a supporting posture. The design structure is simple, and solves the problem that the movable column 115 at the top of the support column 114 cannot maintain a stable arched posture, and the supporting effect on the coal mine passage is poor and cannot provide a supporting effect.

[0025] Among them, each group of the adjusting components 104 is respectively located on one side of the corresponding lifting components 102, the two groups of the lifting components 102 are both located above the driving component 101, the second rod seat 108 is located on one side of one group of the lifting components 102, one end of the second push rod 107 is located on one side of the second push rod seat 108, the other end of the second push rod 107 is located at one end of the first push rod 105, the other end of the first push rod 105 is located on one side of the first rod seat 106, and the first rod seat 106 is located on one side of the other group of the lifting components 102.

Driven by the dual-axis motor 110, the two sliders 113 can be driven to move relative to or toward each other. Then, when the movable column 115 moves, the first push rod 105 and the second push rod 107 are driven to move. The closer the two movable columns 115 are, the greater the upward deflection angle of the first push rod 105 and the second push rod 107 is, and the more obvious the supporting effect on the two arc-shaped brackets 116 is, thereby achieving support for the arc-shaped brackets 116 and ensuring a normal supporting and stable posture.

The setting of the slide bar 112 ensures that when the dual-axis motor 110 drives the slider 113 to move, the stability of the slider 113 is maintained during the movement. Under the drive of the dual-axis motor 110, the two sliders 113 can be driven to move relative to each other or toward each other, and then when the movable column 115 is moved, the slider 113 can move relative to each other. When the column 115 moves, it drives the movement of the first push rod 105 and the second push rod 107. The closer the two movable columns 115 are, the greater the upward deflection angle of the first push rod 105 and the second push rod 107 is, and the more obvious the supporting effect on the two arc-shaped brackets 116 is, thereby achieving support for the arc-shaped brackets 116 and ensuring a normal supporting and stable posture.
