[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0026] refer to Figure 1-7A lifting machine for preventing tilting includes a base 53 and a lifting platform 54. The lifting platform 54 is slidably arranged above the base 53, a plurality of shock-absorbing seats 59 are arranged on the end surface of the base 53, a climbing frame 60 is slidably arranged below the shock-absorbing seat 59, a plurality of crawling wheels 70 are rotatably arranged in the crawling frame 60, a shock-absorbing assembly is arranged between the crawling frame 60 and the shock-absorbing seat 59, a plurality of pressing plates 61 are slidably arranged outside the crawling frame 60, a hard strip 63 is arranged on the bottom end surface of each pressing plate 61, a flexible pad 64 is arranged on the end surface of the pressing plate 61 between two hard strips 63, a plurality of detachable hard pressing blocks 62 are arranged on the end surface of the flexible pad 64, and a plurality of cone nails 65 are arranged on the end surface of the hard pressing block 62.

[0027] When the elevator needs to move, the staff can push the base 53 to move on the ground. The multiple crawling wheels 70 arranged in the crawling frame 60 under the base 53 will contact the ground and roll, so that the elevator body can move quickly. During this process, the shock-absorbing assembly arranged between the crawling frame 60 and the shock-absorbing seat 59 can effectively reduce the vibration of the elevator body, so that the elevator can move stably.

[0028] When the elevator moves to the designated position, the pressure plate 61 will move downward, thereby driving the movement of multiple hard strips 63 and flexible pads 64 on the end surface. The hard strips 63 will contact the ground during the movement, thereby basically supporting and fixing the elevator body. During this process, the hard pressure block 62 will also contact the ground, so that the cone nail 65 can be driven into the ground, thereby reinforcing the elevator as a whole. When the hard pressure block 62 contacts the ground, the flexible pad 64 will also be pressurized and stressed, so that the flexible pad 64 can have a certain ability to absorb vibrations, thereby improving the overall stability of the elevator and ensuring construction safety. During the above process, most of the crawling wheels 70 will still contact the ground, so that the shock absorbing components are stressed, thereby improving the overall stability of the equipment.

[0029] refer to Figure 3 A plurality of second push cylinders 58 are disposed on the end surface of the base 53 , and an output end of each second push cylinder 58 is connected to the end surface of the pressure plate 61 .

[0030] When the lift needs to be supported and fixed, the output end of the second push cylinder 58 can push the pressing plate 61 to move downward, thereby completing the support and fixation of the entire lift.

[0031] refer to Figure 5 A rough surface ring 66 is provided on the end surface of each hard pressing block 62 .

[0032] The outer end surface of the rough surface ring 66 is provided with a plurality of anti-skid stripes, which can effectively increase the contact friction between the hard pressing block 62 and the ground, and improve the supporting and fixing effect.

[0033] refer to Figure 6 A plurality of rotating shafts 69 are arranged inside the crawling frame 60 , and a crawling wheel 70 is rotatably arranged outside each rotating shaft 69 .

[0034] The crawling wheel 70 can rotate outside the rotating shaft 69, thereby driving the device to move. The staff can also install a motor outside the rotating shaft 69 to enable the device to move automatically.

[0035] refer to Figure 6-7 The shock absorbing assembly includes a telescopic rod 68 slidably arranged in the shock absorbing seat 59, one end of the bottom of the telescopic rod 68 extends out of the end surface of the shock absorbing seat 59, and one end of the telescopic rod 68 extending out of the end surface of the shock absorbing seat 59 is connected to the end surface of the crawling frame 60, and one end of the telescopic rod 68 in the shock absorbing seat 59 is connected to a spring 67.

[0036] The setting of the spring 67 enables the telescopic rod 68 and the climbing frame 60 to move up and down, and the vibration generated by the movement can also be effectively absorbed, thereby improving the stability of the elevator when moving.

[0037] refer to Figure 7 The shock absorbing assembly also includes a buffer pad 71 arranged on the bottom end surface of the shock absorbing seat 59.

[0038] When the pressure above the elevator is too heavy, the spring 67 will be stressed to the limit, and the telescopic rod 68 will also be mostly retracted into the shock absorbing seat 59. At this time, the outer end of the telescopic rod 68 will be pressed on the buffer pad 71. The buffer pad 71 is made of elastic shock-absorbing material, which can effectively improve the shock absorption effect, so that the elevator can move stably and complete the work.

[0039] refer to Figure 1-2 Support frames 56 are provided at the four corners of the upper end surface of the base 53 , and a slide rail 57 is provided on the end surface of each support frame 56 , and a lifting platform 54 is slidably provided in the slide rail 57 .

[0040] The arrangement of the support frame 56 and the slide rail 57 enables the lifting platform 54 to move stably above the base 53 .

[0041] refer to Figure 2 A first push cylinder 55 is disposed on the upper end surface of the base 53 , and an output end of the first push cylinder 55 is connected to the end surface of the lifting platform 54 .

[0042] The output end of the first push cylinder 55 can push the lifting platform 54 to move up and down to complete the lifting process. Embodiment 2:

[0043] On the basis of or different from the first embodiment, a plurality of V-shaped anti-slip grooves are provided on the end surface of each hard strip 63 .

[0044] The multiple V-shaped anti-skid grooves on the end surface of the hard strip 63 effectively increase the contact friction between the hard strip 63 and the ground, thereby improving the supporting and fixing effect.
