Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: a lifting work platform, including a lifting work mechanism 1, a positioning platform 2, a cylinder 3, a work platform 4, a supporting wheel 5, a limiting wheel 6, a square sleeve 7, a positioning plate 8, a double-headed servo motor 9, a transmission rod 10, a sleeve 11, a support rod 12, a clamping rod 13, a sleeve 14 and a stabilizing mechanism 15, an adjusting rod 1501, a stabilizing plate 1502, and an anti-slip rubber pad 1503. The upper end of the lifting work mechanism 1 is fixedly connected with the positioning platform 2, and the inner wall of the positioning platform 2 is fixedly provided with a cylinder 3, and the end of the output shaft of the cylinder 3 is fixedly connected with the work platform 4. Square sleeves 7 are fixedly provided at both end surfaces of the lifting operation mechanism 1, and positioning plates 8 are fixedly connected to both ends of the lower surface of the square sleeve 7, and a double-headed servo motor 9 is fixedly installed in the middle of the lower surface of the square sleeve 7, and a transmission rod 10 is fixedly connected to the end of the output shaft of the double-headed servo motor 9, and a sleeve 11 is sleeved on the outer wall of the transmission rod 10, and a support rod 12 is fixedly connected to the upper surface of the sleeve 11, and a clamping rod 13 is fixedly installed on the upper end of the support rod 12, and a sleeve 14 is fixedly connected to the end of the clamping rod 13, and a stabilizing mechanism 15 is installed on the inner wall of the sleeve 14.

[0023] Support wheels 5 are installed at the edge of the lower surface of the workbench 4, and limiting wheels 6 are fixed on the outer walls of both sides of the workbench 4, and the support wheels 5 and the limiting wheels 6 are both in contact with the positioning platform 2, so that when the cylinder 3 drives the workbench 4 to move horizontally, the support wheels 5 and the limiting wheels 6 roll relative to the positioning platform 2 at the same time, thereby making the workbench 4 move stably.

[0024] The positioning plate 8 and the transmission rod 10 are rotationally connected, and the transmission rod 10 and the sleeve 11 are threadedly connected, and the direction of the thread arranged on the outer wall of the transmission rod 10 is symmetrically distributed about the longitudinal center axis of the square sleeve 7, so that the double-headed servo motor 9 drives the transmission rod 10 to rotate, so that the sleeve 11 moves toward or oppositely along the transmission rod 10 at the same time.

[0025] The support rod 12 is slidably connected to the square sleeve 7 , and the square sleeve 7 and the clamping rod 13 form a sliding structure, so that when the sleeve 11 moves, the support rod 12 slides relative to the square sleeve 7 , thereby allowing the clamping rod 13 to extend from the square sleeve 7 .

[0026] The stabilizing mechanism 15 includes an adjusting rod 1501, a stabilizing plate 1502 and an anti-slip rubber pad 1503, and the adjusting rod 1501 is movably mounted on the inner wall of the sleeve 14, and the lower end of the adjusting rod 1501 is movably connected to the stabilizing plate 1502, and the anti-slip rubber pad 1503 is bonded to the lower surface of the stabilizing plate 1502, so as to facilitate enhancing the friction between the device and the ground through the stabilizing mechanism 15, thereby enhancing the stability of the device.

[0027] The adjusting rod 1501 and the sleeve 14 are threadedly arranged, and the adjusting rod 1501 and the stabilizing plate 1502 are rotatably connected, so that the user can rotate the adjusting rod 1501 to move the adjusting rod 1501 downward relative to the sleeve 14, thereby allowing the stabilizing plate 1502 to drive the anti-slip rubber pad 1503 to move downward, allowing the anti-slip rubber pad 1503 to be close to the ground, thereby improving the stability of the device.

[0028] Working principle: When using the lifting platform, first Figure 1-2 and Figure 4-5 As shown, the user starts the lifting mechanism 1 to move the lifting mechanism 1 to the working position, and then the user starts the double-headed servo motor 9, and then the double-headed servo motor 9 drives the transmission rod 10 to rotate relative to the positioning plate 8, and then the sleeve 11 moves in the opposite direction along the transmission rod 10 at the same time, and then the sleeve 11 drives the support rod 12 to slide relative to the square sleeve 7, and then the support rod 12 drives the clamping rod 13 to extend out of the square sleeve 7, and then the user rotates the adjustment rod 1501, and then the adjustment rod 1501 moves downward relative to the sleeve 14, and then the adjustment rod 1501 drives the stabilizing plate 1502 The anti-skid rubber pad 1503 is moved downward to make it close to the ground. Similarly, the remaining double-head servo motors 9 and the stabilizing mechanism 15 are operated, so that the friction between the anti-skid rubber pad 1503 and the ground is improved to improve the stability of the device. Therefore, the stability of the device is improved, thereby avoiding the displacement of the device when working, and improving the safety of the device. Then the user climbs onto the workbench 4 through the ladder, and then the user starts the lifting operation mechanism 1 so that the lifting operation mechanism 1 drives the workbench 4 to move upward. At this time, the user performs the operation. When the device needs to move the workbench 4 horizontally, as shown in FIG. Figure 1 and Figure 3 As shown, the user starts the cylinder 3, and then the cylinder 3 drives the workbench 4 to move horizontally. As the workbench 4 moves, the workbench 4 drives the supporting wheels 5 and the limiting wheels 6 to roll relative to the positioning platform 2, thereby completing the adjustment of the horizontal position of the workbench 4, thereby increasing the operating range of the device and further improving the practicability of the device.
