A telescopic component 2 is arranged above the support frame 1. The telescopic component 2 includes a sliding bar 201. The telescopic component 2 is movably penetrated through the right side of the support frame 1. The lower surface of the sliding bar 201 is movably attached to a limit sleeve 202. The shape of the limit sleeve 202 is U-shaped. The limit sleeve 202 is fixedly connected to the top inner surface of the support frame 1. A top piece 203 is fixedly connected above the sliding bar 201. A hydraulic push rod 204 is fixedly connected to the right side of the top piece 203. The right end of the hydraulic push rod 204 is fixedly connected to a support piece 205. The support piece 205 is fixedly connected to the upper part of the support frame 1. A moving component 3 is arranged below the support frame 1. The moving component 3 includes a bottom plate 301. The bottom plate 301 is fixedly connected to the lower part of the support frame 1. Four universal wheels 302 are rotatably connected below the bottom plate 301, and are respectively arranged at the four corners below the bottom plate 301. The universal wheels 302 are equipped with a self-locking mechanism, which can lock to make the wheels unable to rotate, which is the prior art.

[0021] During use, first move the bottom plate 301 through the universal wheels 302 so that the support frame 1 is placed in the required place. At this time, lower the hoisting component 5 through the electric winch 4 to hoist the rotary joint. When the position of the hoisting component 5 cannot correspond to the rotary joint, start the hydraulic push rod 204. Push the top piece 203 through the hydraulic push rod 204 to make the sliding bar 201 extend leftward on the support frame 1, and then drive the electric winch 4, so that the hoisting component 5 moves, so as to facilitate the hoisting of the rotary joint in the deeper part of the production line. When the sliding bar 201 extends leftward on the support frame 1, it will slide in the limit sleeve 202, and the limit sleeve 202 can keep the sliding bar 201 extending stably.

[0022] Embodiment 2

[0023] Please refer to Figures 1-3, on the basis of Embodiment 1, an electric winch 4 is fixedly installed below the sliding bar 201. The electric winch 4 is specifically a winch that can be remotely controlled for automatic winding and fixing, which is a prior art. A hoisting assembly 5 is arranged below the electric winch 4. The hoisting assembly 5 includes a lifting plate 501. The lifting plate 501 is connected to the electric winch 4 by a rope. A fixed connection is provided below the lifting plate 501 with an electric slide rail 502. A jaw 503 is slidably connected below the electric slide rail 502. The jaw 503 will not fall off below the electric slide rail 502. The electric slide rail 502 can drive the jaw 503 to slide, which is a prior art. By driving the two jaws 503 to slide below it through the electric slide rail 502, the rotary joint can be clamped. The number of jaws 503 is two.

The left end of the telescopic rod 602 is fixedly connected to the right side of the lifting plate 501.

[0024] During use, on the basis of Embodiment 1, when the sliding bar 201 drives the electric winch 4 to extend leftward on the support frame 1, the electric winch 4 will drive the rope to displace the lifting plate 501. At this time, the telescopic rod 602 will extend. By adjusting the telescopic rod 602 until the rope below the electric winch 4 is vertical, at this time, the rope is released through the electric winch 4 to make the lifting plate 501 descend. The lifting plate 501 will drive the telescopic rod 602 to make the sliding sleeve 601 slide on the outer surface of the support frame 1, so as to facilitate stable lowering or lifting. After the lifting plate 501 is lowered, the jaws 503 are driven to slide below it through the electric slide rail 502, so that the two jaws 503 clamp both ends of the rotary joint. After clamping, the rope is wound by the electric winch 4 to lift the clamped rotary joint, achieving the effect of facilitating the hoisting of the rotary joint from the production line.
