At this time, the fixed plate 208 will also rotate, thereby driving the hydraulic push rod 210 to rotate. When it is rotated to the appropriate position, the limiting column 206 is released, so that the spring 205 rebounds, so that the limiting column 206 is engaged in the limiting hole of the limiting plate 202, thereby fixing the device.

A lifting arm 301 is provided on one side surface of the connecting shaft 207, a take-up reel 302 is provided on one side surface of the lifting arm 301, a lifting rope 303 is provided on the outer surface of the take-up reel 302, and a lifting rope 303 is provided on the outer surface of the take-up reel 302. 03, a hydraulic rod 304 is fixedly connected to one side surface of the lifting arm 301, a sliding groove 305 is provided on one side surface of the lifting arm 301, a sliding column 306 is provided inside the sliding groove 305, a connecting frame 307 is fixedly connected to one side surface of the sliding column 306, a first pulley 308 is fixedly connected to one side surface of the connecting frame 307, a second pulley 309 is fixedly connected to one side surface of the lifting rope 303, When the lifting part 310 is in operation, the motor 311 is turned on to reel in the wire reel 302, thereby reeling in the lifting rope 303. At this time, the outer surfaces of the first pulley 308 and the second pulley 309 are rotated by force, thereby routing the lifting rope 303. When the lifting part 310 is in operation, the motor 311 is turned on to reel in the wire reel 302, thereby reeling in the lifting rope 303. At this time, the outer surfaces of the first pulley 308 and the second pulley 309 are rotated by force, thereby routing the lifting rope 303. When the lifting part 310 is in operation, the motor 311 is turned on to reel in the wire reel 302, thereby reeling in the lifting rope 303. When the lifting part 310 is in operation, the motor 311 is turned on to reel in the wire reel 302, thereby reeling in the lifting rope 303.

[0025] Furthermore, one side surface of the lifting arm 301 is fixedly connected to the hydraulic push rod 210, and one side surface of the connecting frame 307 is fixedly connected to the hydraulic rod 304.

[0027] Working principle: First, when lifting is required, the device needs to be adjusted to a suitable position, and the limiting column 206 is pulled first, so that the limiting column 206 squeezes the spring 205 inside the connecting block 204, so that the limiting column 206 is separated from the limiting plate 202, and then the rotating plate 203 is rotated. At this time, the fixed plate 208 will also rotate, thereby driving the hydraulic push rod 210 to rotate. When it is rotated to the appropriate position, the limiting column 206 is released, so that the spring 205 rebounds, and the limiting column 206 is engaged in the limiting hole of the limiting plate 202. , thereby fixing the device, and then lifting is carried out. First, the position of the sliding column 306 is adjusted, and the hydraulic rod 304 is used to control its extension and contraction length. Then, the goods to be lifted are hung on the lifting part 310, and then the motor 311 is turned on to reel the wire reel 302, so that the lifting rope 303 is reeled. At this time, the outer surfaces of the first pulley 308 and the second pulley 309 will be forced to rotate, so that the lifting rope 303 is routed. When it is reeled to a certain extent, it stops reeling, and then the hydraulic push rod 210 lifts the lifting arm 301 to complete the lifting.
