[0003] In order to be able to move, a conventional lifting platform usually has universal wheels added to the bottom or uses machinery for transportation. Mechanical transportation is very laborious, and universal wheels generally do not have a locking mechanism, or even if there is a locking mechanism, the platform will slide due to the smooth bottom of the wheel, making operations on the platform unstable.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] Reference Figure 1-Figure 3As shown, the coating side screw electric lifting platform includes a base plate 1 and a universal wheel 2, and a plurality of universal wheels 2 are fixedly connected to the four corners of the lower end surface of the base plate 1; a stabilizing mechanism is arranged on the base plate 1, and the stabilizing mechanism includes a hollow rod 3, a leg 4, a suction cup 5, a limit plate 6, a fixed block 7, a sliding rod 8, and an air bag 9. A plurality of hollow rods 3 are fixedly connected to the four corners of the base plate 1, and the leg 4 is slidably connected to the outer surface of the hollow rod 3. The leg 4 is hollow inside and connected to the hollow rod 3. The suction cup 5 is fixedly connected to the lower end surface of the leg 4, and a plurality of limit plates 6 are fixedly connected to the lower end surface of the leg 4. They are respectively fixedly connected at the four corners of the base plate 1, the fixed block 7 is fixedly connected to the side wall of the leg 4, the sliding rod 8 is hinged on the side wall of the fixed block 7 away from the end of the leg 4, the sliding rod 8 is hinged on the fixed block 7 and can only move in the horizontal direction, and cannot move in the vertical direction. A limiting groove is provided on the limiting plate 6, and the limiting groove is composed of two vertical grooves, one long and one short, and a horizontal groove connected thereto. The sliding rod 8 is slidably connected in the limiting groove. When it needs to move, the sliding rod 8 is located at the highest point of the limiting groove, and the position of the leg 4 is higher than the universal wheel 2, and the universal wheel 2 can move freely.

[0017] Two screw rods 10 are rotatably connected to the base plate 1, and the screw rods 10 are threadedly connected with nut seats 11, and a platform plate 12 is fixedly connected between the two nut seats 11. Multiple airbags 9 are respectively fixedly connected at the four corners of the upper end surface of the base plate 1. Multiple airbags 9 are fixedly connected to the platform plate 12, and the airbags 9 are fixedly connected to the hollow rod 3 through the air pipe. A limiting block is set on the upper end surface of the screw rod 10, and the lower end of the screw rod 10 passes through the base plate 1 and is connected to an external servo motor. Starting the servo motor to drive the screw rod 10 to rotate will drive the nut seat 11 to rise, thereby causing the platform plate 12 to rise, and the limiting block prevents it from being out of the groove. The rising of the platform plate 12 will stretch the airbag 9. After the airbag 9 is stretched, the air pressure decreases, and the gas in the hollow rod 3 enters the airbag 9 through the air pipe, and the air pressure in the hollow rod 3 also decreases.

[0018] One end of the slide bar 8 away from the limit plate 6 is fixedly connected to a pedal 13, and baffles are provided on both sides of the pedal 13. Stepping on the pedal 13 drives the slide bar 8 to move downward, and the baffles facilitate left and right force, thereby driving the slide bar 8 to move left and right.

[0019] A return spring 14 is fixedly connected between the supporting leg 4 and the bottom plate 1 , and a compression spring 15 is fixedly connected between the fixing block 7 and the sliding rod 8 .

[0020] When in use, first use the universal wheel 2 to move the device to the working position, step on the foot pedal 13 to drive the slide bar 8 to move downward, and the downward movement of the slide bar 8 drives the support leg 4 to move downward. After the support leg 4 moves down and touches the ground, manually lift the bottom plate 1 to make the universal wheel 2 leave the ground. When the slide bar 8 moves down to the lowest point, twist the foot pedal 13 to the left to make it stuck in the short groove of the limit groove. A part of the gas in the suction cup 5 under the support leg 4 slips out from under the suction cup 5 under the squeeze, but the amount that slips out is small, and the adsorption force of the suction cup 5 is weak. However, at this time, the bottom plate 1 is at a low place with a low center of gravity. The wide support leg 4 and the suction cup 5 are sufficient to support the bottom plate 1, so that personnel can work stably. When it is necessary to spray the wall above, start the external servo motor to drive the screw rod 10 to rotate, drive the nut seat 11 and the platform plate 12 to rise. As the platform plate 12 rises, the rising of the platform plate 12 will stretch the airbag 9. After the airbag 9 is stretched, the air pressure decreases, and the gas in the hollow rod 3 and the leg 4 enters the airbag 9 through the trachea. The air pressure in the hollow rod 3 and the leg 4 decreases, and the suction cup 5 tightly sucks the ground to ensure the stability of the device. The higher it rises, the tighter the suction is, so that the safety of the operation can be guaranteed when the center of gravity of the personnel rises to a high place. When the position needs to be adjusted again, the reverse motor makes the platform plate 12 descend, and the air pressure of the airbag 9 is restored to drive the gas back into the hollow rod 3 and the leg 4. At this time, the suction force of the suction cup 5 is very weak, and the bottom plate 1 is slightly lifted to drive the limit plate 6 to rise. The slide bar 8 is reset under the action of the extrusion spring 15 and the reset spring 14, driving the leg 4 to rise above the universal wheel 2, and the device can be moved again, and the above operation can be repeated.
