[0027] Rotation function, the maintenance platform rotates the platform table in a 360-degree range without a dead angle based on a motor-driven turntable mechanism, and cooperates with an angle sensor to realize adjustment of any angle, so that the maintenance personnel can realize maintenance of any position of the gearbox without walking, and the maintenance efficiency is improved.

[0028] The structure, principle and use method of the embodiment will be described more precisely in combination with the specific description of the accompanying drawings.

[0029] Reference Figures 1 to 4 The maintenance platform comprises an equipment support assembly for providing support, a platform main body assembly for providing a maintenance object function, a rotation function module is integrated in the platform main body assembly, and a height adjustment module is arranged between the equipment support assembly and the platform main body assembly.

[0030] The equipment support assembly, the steel pipe frame 110 of the equipment support is formed by welding steel pipes, and an adjusting foot bolt 130 is arranged at the bottom of the equipment support. Meanwhile, a steel plate 120 is arranged on the equipment support, the steel plate and the steel pipe frame are fixed by welding, and mounting points are formed on the steel plate by drilling holes.

[0031] The platform main assembly comprises a bottom plate 210, a top plate 220, a gear box 230, a bearing box 240 and auxiliary support rods 250. The bottom plate 210 and the top plate 220 are circular steel plates. The gear box 230 is arranged at the central position above the bottom plate 210 and is fixed to the bottom plate 210 by bolts. A connecting cap 260 is arranged below the bottom plate and the gear box. The connecting cap 260 is fixedly connected to the top of the lead screw in the height adjustment module by a nut. The gear box 230 is provided with a large gear and a small gear which are engaged with each other. The small gear is mounted on the motor shaft of the second motor and is driven by the second motor. The large gear is mounted on a gear shaft which is mounted on the gear box shell by two groups of bearings. The gear shaft is arranged at the center of the gear box shell. The gear box shell is provided with the bearing box 240 at the position where the bearings are arranged. The bearing box 240 is arranged above the gear box shell and is fixedly installed by bolts. The top end of the gear shaft 340 is fixedly connected to the center of the top plate 220 by a flange plate. The rotation of the gear shaft 340 drives the rotation of the top plate. Six auxiliary support rods 250 are arranged between the bottom plate and the top plate. The six auxiliary support rods 250 are arranged at equal intervals along the rotation axis. The lower end of each auxiliary support rod 250 is fixedly installed on the bottom plate. The upper end of each auxiliary support rod 250 is provided with a ball 251 which is in rolling contact with the top plate. During the rotation of the top plate relative to the bottom plate, the balls at the top of the auxiliary support rods provide auxiliary support for the top plate, which is beneficial to the stability of the top plate.

[0032] Further, a rolling guide is arranged on the lower surface of the top plate 220 at the position corresponding to the balls. The rolling guide is annularly arranged along the rotation axis and has an arc-shaped cross section. The rolling guide cooperates with the balls, which further improves the stability of the platform.

[0033] The rotation function module comprises a second motor 310, a small gear 320, a large gear 330 and a gear shaft 340. The second motor is fixedly installed on the bottom plate by bolts. The motor shaft of the second motor penetrates into the gear box and is provided with the small gear. The rotation of the gear shaft is driven by the gear transmission.

[0034] The height adjustment module is described in detail with reference to Figure 5The system includes a worm gear 410, a worm wheel 420, a lead screw 430, and four guide posts 440, all driven by a first motor. The top of each guide post is fixedly connected to the base plate, and the guide post slides in cooperation with a guide sleeve located in the steel plate 120, guiding the vertical movement of the base plate linearly. The housing 450 of the worm gear is fixedly mounted on the steel plate 120 of the equipment support. The lead screw 430, mounted in the worm wheel, passes through the steel plate from bottom to top and reaches the upper space, where it is fixed to the main platform assembly. Specifically, the worm wheel 420 has an internal thread that engages with the lead screw. As the worm wheel rotates, it provides a driving force to the lead screw, causing it to adjust vertically. The worm wheel, worm, and lead screw provide an overall lifting effect on the main platform assembly. The driving force comes from the first motor (not shown in the figure), which is mounted on the outside of the worm wheel housing, with its shaft connected to the worm. The motor drives the worm wheel, thereby driving the lifting lead screw to rise or fall.

[0035] The aforementioned lead screw 430 includes a lead screw section 431, a smooth shaft section 432, and a threaded section 433 from bottom to top. The threaded section is used to fix and connect to the connecting cap below the base plate, and the connection method is to tighten with a nut.

[0036] The driving of the first and second motors, including forward and reverse control, can be achieved by electric button operation or wireless remote control operation. This is a mature technology and will not be elaborated further.

[0037] The two modules described above allow for rapid adjustment of the height and angle of the top plate, thereby enabling adjustment of the height and posture of the gearbox placed on the maintenance platform to meet the maintenance needs of different parts. Adjustments can be made according to the individual conditions of the maintenance personnel. This technology can effectively reduce labor intensity and improve maintenance efficiency.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
