[0034] Working principle: when in use, first move the device along the foundation pit to the vicinity of the cement pipe, ensure that the guide roller 108 is in contact with the inside of the foundation pit during the movement, and ensure that the device forms a tendency to align, then start the lifting motor 302 to unwind, and when the lifting motor 302 unwinds, the worm gear reducer 301 drives the reducer output shaft 303 to unwind the winding roller 304, thereby extending the free length of the lifting rope 305; Then, the driven clamp 409 and the active clamp 404 are pulled out, and the electric push rod 406 is started to open the driven clamp 409 and the active clamp 404, and then the two are sleeved on the surface of the cement pipe, and then the electric push rod 406 is started to contract, and the electric push rod 406 pulls the driven clamp 409 and the active clamp 404 to close, so as to fix the cement pipe, and then the free end of the safety belt 502 is wrapped from the bottom of the cement pipe, and passes through the gap inside the second binding column 413, and then passes through the gap at the bottom of the unfolded lock belt flap 507, and then the safety belt 502 is tightened, and the lock belt flap 507 is closed, and the lock belt flap 507 is fixed by the clamping block 506, and at the same time, the clamping belt teeth 508 are inserted into the surface of the safety belt 502, and when the safety belt 502 is pulled downward, the meshing with the clamping belt teeth 508 is deepened, and the tendency of the lock belt flap 507 to turn inward is strengthened, so as to realize the self-locking of the binding; Then, the main frame 101 of the device is partially moved to the top of the cement pipe, and the lifting motor 302 is started to reel. When the lifting motor 302 reels, the reducer output shaft 303 is driven by the worm gear reducer 301 to reel the reeling roller 304, so that the free length of the lifting rope 305 is contracted. When reeling, the positioning pin 208 is aligned with the positioning hole 309. As the lifting rope 305 is gradually reeled, the positioning pin 208 is inserted into the positioning hole 309, and the separation hanging cylinder 308 is attached to the bottom of the lifting cylinder 207. Then, the lifting rope 305 is continuously reeled, so that the cement pipe is suspended in the air, which is convenient for its subsequent movement and docking. During the movement, the main frame 101 is pushed to move along the foundation pit, so that the suspended cement pipe is moved to other positions of the foundation pit; During docking, the lifting cylinder 207 is slid upwards so that the positioning pin 208 is pulled out, and a section of the lifting rope 305 extending from the bottom end of the guide slide cylinder 202 can move freely, thereby ensuring that the suspended cement pipe can turn without large shaking, thereby facilitating the adjustment of the suspended cement pipe docking, and then changing the angle of the suspended cement pipe to promote its docking.
