[0053] In a specific implementation, a plurality of guide cylinders 32 are provided, and a plurality of guide rods 33 are provided corresponding to the guide cylinders 32 , and the plurality of guide cylinders 32 are evenly distributed on the moving frame 1 .

[0054] In some embodiments, see Figure 2 The roller 5 includes a roller body 51 and a mounting seat 52, and the roller body 51 is rotatably connected to the mounting seat 52. The shock-absorbing assembly 2 includes a positioning rod 21, a positioning cylinder 22 and a shock-absorbing elastic member 23.

When the road surface on which the mobile frame 1 moves is bumpy, the shock-absorbing elastic member 23 can buffer the impact force generated by the collision between the roller 5 and the road surface, avoid the vibration of the mobile frame 1, and the collision with the roller 5 affects the performance of the equipment, affects the bearing effect on the opening machine, and the mobile frame 1 moves stably, reducing the pushing strength of the staff. The positioning rod 21 and the positioning cylinder 22 are slidably plugged in and matched, which can guide the telescopic direction of the shock-absorbing elastic member 23 and prevent the shock-absorbing elastic member 23 from deviating from its own axis when compressed.

When there is an obstacle or threshold on the road surface, the rotating rod 62 is rotated to rotate around the rotating drum 61 until the crossing wheel 63 at the top touches the ground. At this time, the rotating rod 62 originally located at the top crosses the obstacle. The setting of the crossing component 6 does not require the staff to lift the mobile frame 1 as a whole to cross the obstacle, thereby reducing the labor intensity.

[0057] It should be noted that, in this embodiment, the bottom of the movable frame 1 does not need to be provided with rollers 5 .

[0058] During specific implementation, in the moving state, the two span wheels 63 located at the bottom cooperate to support the moving frame 1 and drive the moving frame 1 to move.

[0059] In some embodiments, see Figure 3 There are three rotating rods 62, and the angles between two adjacent rotating rods 62 are the same. The three rotating rods 62 are evenly distributed, so that when any two adjacent rotating rods 62 cooperate to support the moving frame 1, the height of the moving frame 1 is the same, avoiding the height change of the opening machine during the movement, and improving the movement stability.

The cross-sectional area of ​​the fixed base 72 gradually increases from top to bottom, which can stably support the mobile frame 1 and improve the stability of the support.

[0061] During specific implementation, a plurality of support driving members 71 are provided, and the plurality of support driving members 71 cooperate to support the movable frame 1 .

[0063] In some embodiments, see Figure 1 A limit rod 12 is provided on the top of the mobile frame 1. The limit rod 12 is arranged in the horizontal direction. The limit rod 12 can abut against the bottom surface of the fixed plate 4 to limit the downward movement of the fixed plate 4. The limit rod 12 can abut against the fixed plate 4 to increase the contact area between the mobile frame 1 and the fixed plate 4 and reduce the local force strength.

[0064] In some embodiments, the roller 5 includes a pair of fixed wheels and a pair of universal wheels, the two fixed wheels are arranged on one side of the bottom of the mobile frame 1, and the two universal wheels are arranged on the other side of the bottom of the mobile frame 1.
