[0034] In one of the embodiments, a plurality of mounting grooves 17 are provided on the sliding contact surface between the adjusting block 7 and the inner wall of the limiting groove 15, and a ball 16 is movably installed on the mounting groove 17, and the ball 16 is in rolling contact with the inner wall of the limiting groove 15, thereby reducing the friction between the adjusting block 7 and the limiting groove 15, making the process of turning the hand wheel 6 easier and more labor-saving, while reducing the wear of the adjusting block 7 and increasing the service life of the adjusting block 7.

[0035] In one preferred embodiment, a threaded hole matched with the adjusting screw rod 14 is opened on one side of the top of the adjusting block 7, and the adjusting block 7 is threadedly connected to the adjusting screw rod 14 through the threaded hole opened on one side of the top of the adjusting block 7.

[0038] The working principle of the utility model is as follows: the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When the running-in device body 2 needs to be moved, the device running-in device body 2 is directly pushed. Through the rolling contact between the universal wheel 4 at the bottom of the bottom frame 1 and the ground, the device can be easily pushed to move without consuming a lot of manpower and material resources, thereby improving the flexibility and operating efficiency of the device. When the device is moved to the specified position, the hand wheels 6 on both sides of the device can be rotated, and the rotation of the hand wheels 6 drives the worm 18 to rotate. Through the meshing effect of the worm 18 and the worm wheel 13, the worm wheel 13 drives the adjusting screw 14 By rotating, the two adjusting blocks 7 can be stably moved vertically by adjusting the threaded transmission of the screw rod 14 and the adjusting block 7, and the sliding relationship between the adjusting block 7 and the limit groove 15. The movement of the adjusting block 7 drives the positioning rod 9 to move, and the positioning rod 9 drives the pressure plate 11 to move. Therefore, by rotating the handwheel 6, the vertical positions of the two pressure plates 11 can be changed at the same time, so that the pressure plate 11 moves downward and directly contacts the ground, increasing the contact area and friction between the equipment and the ground, and improving the stability of the equipment when it is used at a fixed point. At the same time, relying on the self-locking property of the worm 18 and the worm wheel 13, the stability of the pressure plate 11 when it contacts the ground can be ensured.

[0039] The device achieves mobility through a mobile structure composed of multiple universal wheels 4. The universal wheels 4 are inevitably worn out during use. When individual universal wheels 4 are severely worn, they need to be replaced. When the device needs to be moved, the device can be moved to an area with a groove on the ground, so that the damaged universal wheel 4 is in a suspended state. Then the staff directly pulls the pull ring 20 above the damaged universal wheel 4. The movement of the pull ring 20 drives the limit rod 22 to slide on the fixed groove 23. At the same time, the movement of the limit rod 22 drives the slider 27 to slide on the outer wall of the slide rod 21 and squeeze the spring 19. As the limit rod 22 moves, the limit The rod 22 will be separated from the inside of the slot 24 on the mounting block 25. After the mounting block 25 loses the clamping limit between the limit rod 22 and the slot 24, the mounting block 25 can be directly removed from the inside of the connecting slot 26 to complete the removal of the universal wheel 4. Then, a new universal wheel 4 is replaced, so that the mounting block 25 on the top of the universal wheel 4 is clamped into the inside of the connecting slot 26 again, and the limit on the pull ring 20 is released. The limit rod 22 will be clamped into the inside of the slot 24 under the elastic action of the spring 19 to complete the fixed installation of the universal wheel 4. The fixing method of the universal wheel 4 adopts a quick-release structure. Compared with the traditional bolt fixing, this design provides users with a more convenient operating experience. When the universal wheel 4 needs to be replaced or maintained, the user does not need to use any tools, and can easily remove the universal wheel 4 by simply pulling the pull ring 20. This quick-release structure not only saves the tedious steps of tightening the bolts, but also greatly shortens the time for maintenance and inspection, and improves the work efficiency of the staff.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
