[0024] The utility model is further described below in conjunction with embodiments.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 4 The support assembly 5 includes an electric push rod 51 arranged at the bottom of the base plate 1, a fixed plate 52 arranged at the telescopic end of the electric push rod 51, a support rod 53 is arranged on the outer surface of the fixed plate 52, a sleeve 54 is arranged at one end of the support rod 53, four groups of sleeves 54 are arranged corresponding to the universal wheel 3, and the inner diameter of the sleeve 54 is larger than the diameter of the universal wheel 3, a buffer layer 55 is arranged on the inner wall of the sleeve 54, and the inner side of the buffer layer 55 contacts the outer surface of the universal wheel 3, a threaded hole 521 is opened on the upper surface of the fixed plate 52, and four groups of threaded holes 521 are opened, and the insides of the four groups of threaded holes 521 are all threadedly connected with threaded rods 56, and the bottom of the threaded rod 56 is provided with an elastic gasket 561, and the upper end of the threaded rod 56 is penetrated through the bottom plate 1 The outer surface of the threaded rod 56 is movably connected to the inside of the base plate 1. Since the universal wheel 3 itself has a braking function, after the overall structure is moved to the designated place, the extension of the electric push rod 51 drives the fixed plate 52 and the support rod 53 to move downward, so that the sleeve 54 wraps the universal wheel 3, which not only provides an additional support point, but also the buffer layer 55 arranged inside it can absorb vibration, reduce shaking during operation, and improve stability. At the same time, the combination of the threaded rod 56 and the elastic gasket 561 further increases the stability of the structure, makes the force more even, and improves the service life of the support assembly 5. When the structure needs to move laterally, it can be pushed again by simply contracting the electric push rod 51.

[0027] The buffer layer 55 is a component made of natural rubber, which not only has a certain wear resistance but also can effectively absorb vibration energy and reduce the vibration transmitted to the overall structure.

[0028] The lifting assembly 4 includes a motor 41 arranged on the upper surface of the base plate 1, a screw rod 42 fixedly installed at the output end of the motor 41, and a guide rod 43 arranged on the upper surface of the base plate 1. A groove 21 is opened on the upper surface of the working platform 2, and two groups of grooves 21 are provided. The inner walls of the two groups of grooves 21 are provided with connecting blocks 44, and the interior of one group of connecting blocks 44 is threadedly connected to the outer surface of the screw rod 42, and the interior of the other group of connecting blocks 44 is movably connected to the outer surface of the guide rod 43. The screw rod 42 is driven to rotate by the motor 41. Since the screw rod 42 is threadedly connected to the connecting block 44 on the working platform 2, the rotational motion is converted into linear motion, thereby realizing the up and down movement of the working platform 2, which is convenient for adjustment according to the required height, and the guide rod 43 is used to ensure that the working platform 2 can remain stable and move along the correct path during lifting and lowering to avoid tilting.

[0029] The rectangular support frame 6 on the upper surface of the base plate 1 is symmetrically arranged in two groups. A slide groove 61 is opened on one side of each group of rectangular support frames 6. A slider 62 is movably connected inside each group of slide grooves 61. One side of the two groups of sliders 62 is fixedly connected to the inner wall of the corresponding groove 21, respectively, to further increase the stability of the movement of the working platform 2.

[0030] The upper surface of the working platform 2 is provided with an anti-skid plate 7 to prevent workers from slipping when working outdoors or when concrete paddle leaks onto the upper surface of the working platform 2 .

[0031] A guardrail 8 is provided on the upper surface of the working platform 2, and a movable door 81 is hinged on one side of the guardrail 8 to protect personnel from accidental falling injuries.

[0032] The guardrail 8 is provided with an anti-falling net 82 inside, and the outer surface of the guardrail 8 is provided with a safety rope 83, which further enhances the safety of high-altitude operations, prevents tools or materials from falling, and also provides assistance for personnel evacuation in emergency situations.

[0033] Specifically, since the universal wheel 3 itself has a braking function, after the entire structure is moved to a designated place, the extension of the electric push rod 51 drives the fixed plate 52 and the support rod 53 to move downward, so that the sleeve 54 wraps the universal wheel 3, which not only provides an additional support point, but also has a buffer layer 55 inside. Since the buffer layer 55 is a component made of natural rubber, it not only has a certain wear resistance, but also can effectively absorb vibration energy, reduce the vibration transmitted to the overall structure, reduce shaking during operation, and improve stability. At the same time, the combination of the threaded rod 56 and the elastic gasket 561 further increases the stability of the structure, makes the force more even, and improves the service life of the support assembly 5. When the structure needs to move laterally, it only needs to be pushed again by contracting the electric push rod 51. During normal operation, the motor 41 drives the screw rod 42 to rotate. Since the screw rod 42 is threadedly connected to the connecting block 44 on the working platform 2, the rotational motion is converted into linear motion, thereby achieving The working platform 2 can move up and down, so it is easy to adjust according to the required height, and the guide rod 43 is used to ensure that the working platform 2 can remain stable and move along the correct path when it is raised and lowered to avoid tilting. Because the inner walls of the two groups of grooves 21 are also provided with sliders 62, and the sliders 62 and the slide grooves 61 on one side of the rectangular support frame 6 are movably connected, the stability of the movement of the working platform 2 can be further increased. In addition, since the upper surface of the working platform 2 is provided with an anti-slip plate 7, it can prevent workers from slipping when working outdoors or when concrete paddles leak on the upper surface of the working platform 2. Because the upper surface of the working platform 2 is provided with a guardrail 8, a movable door 81 is hinged on one side of the guardrail 8, and an anti-fall net 82 is provided inside the guardrail 8, and a safety rope 83 is sleeved on the outer surface of the guardrail 8, it can not only protect people from accidental falls and injuries, but also further enhance the safety of high-altitude operations, prevent tools or materials from falling, and also provide assistance for the evacuation of people in emergency situations.
