[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] The rotating mechanism includes a fixed box 3, a cover plate 301, a circular groove 302, a driving motor 304, a worm 305, a worm wheel 306, a connecting shaft 307, an arc block 308 and a mounting frame 309.

[0028] There is a circular hole 303 in the middle of the upper surface of the cover plate 301, and the connecting shaft 307 passes through the circular hole 303 and is fixedly connected to the bottom surface of the mounting frame 309. The outer surface of the worm 305 is meshed with the outer surface of the worm wheel 306. By setting up a rotating mechanism, it is convenient to rotate and adjust the lifting direction according to actual use needs when performing lifting operations in blind spots of oil platforms to meet the use needs of different positions. In addition, when performing lifting operations, the entire base 1 is supported by the support column 204 and leaves the ground with good stable support.

[0029] After the base 1 is pushed and the moving wheel 2 installed on the bottom of the base 1 is moved to the operating position, the first hydraulic cylinder 203 pushes the support column 204 to descend and drives the support base 205 to descend so that the bottom surface of the support base 205 contacts the ground and then the entire base 1 is propped up away from the bottom for stable lifting operation.

[0030] Embodiment 2: Based on embodiment 1, a lifting mechanism is arranged above the cover plate 301, and the lifting mechanism includes a protection unit and a lifting unit. The protection unit includes a damping rod 318, a protection plate 319, a compression spring 320, an arc-shaped elastic protection plate 321 and an airbag 322.

The second hydraulic cylinder 310 is fixedly installed on the inner bottom surface of the mounting frame 309, the lifting column 311 is installed on the output end of the second hydraulic cylinder 310, the connecting seat 312 is fixedly connected to the upper surface of the lifting column 311, the placement groove 313 is opened on the upper surface of the connecting seat 312, the connecting block 314 is fixedly connected to the side of the connecting seat 312, the limiting hole 315 runs through the upper surface of the connecting block 314, the fixed circular plate 316 is fixedly installed on the inner bottom surface of the mounting frame 309, the limiting column 317 is fixedly installed on the fixed circular plate 316, and a lamp post 323 is fixedly installed on the upper surface of the mounting frame 309. A lampshade 324 is fixedly installed on the surface of one end of the column 323, and a light bulb 325 is fixedly installed on the inner wall of the lampshade 324. The lamp column 323 is symmetrically distributed at the four corners of the upper surface of the installation frame 309, the second hydraulic cylinder 310 is symmetrically distributed at the four corners of the inner bottom surface of the installation frame 309, and the fixed circular plate 316 is symmetrically distributed on the four sides of the inner bottom surface of the installation frame 309.

The connecting block 314 is installed on the side of the connecting seat 312. When the connecting seat 312 is lifted, the connecting block 314 can move and limit on the outer surface of the limiting column 317 to keep the lifting stable.

[0032] After the lift object is placed on the inner bottom surface of the placement groove 313, the second hydraulic cylinder 310 pushes the lifting column 311 to rise and drives the connecting seat 312 to rise, thereby performing the lifting operation. When the connecting seat 312 rises, it drives the connecting block 314 to move on the outer surface of the limiting column 317 to keep the lifting path stable. The damping rod 318 and the protective plate 319 arranged on the outer side of the mounting frame 309 can collide when hit by an object, so that the arc-shaped elastic protective plate 321 moves to the sides and inward to squeeze the airbag 322 and push the protective plate 319 to move inward to squeeze the damping rod 318 and the compression spring 320, so that the damping rod 318 and the compression spring 320 generate a reset elastic force to buffer the collision to prevent the collision from affecting the lifting operation.
