[0021] The effect achieved by the entire embodiment 1 is that, by setting the first rotating block 407, when the pitch angle of the lifting plate 401 changes, the connecting rod 408 can be always moved vertically downward under the action of gravity, so as to avoid deformation caused by the connecting rod 408 being subjected to oblique force; by setting the second rotating block 409, when the two hanging rings 410 are at different horizontal lines and under the constraint of the transport pipe, the angle can be adaptively changed, so as to avoid deformation caused by the hanging ring 410 being subjected to oblique force; the decoration is moved to the top of the transport pipe by the moving wheel 11, and then the hydraulic rod 34 is started to drive the lifting plate 401 to move downward through the slider 406, the first rotating block 407, the connecting rod 408 and the second rotating block 409 in sequence, so that the hanging ring 410 drops to a suitable position, and the limit plate 411 is screwed. The bolts between the limit plate 411 and the lifting ring 410 are used to separate the limit plate 411 and the lifting ring 410, and the conveying pipe is placed inside the two lifting rings 410, and then the limit plate 411 is connected to the lifting ring 410 by bolts, so as to fix the conveying pipe, and then the conveying pipe is suspended by the hydraulic rod 34. Since the conveying pipe is supported by the two limit plates 411, it is more stable and not easy to shake during the suspension process. When it is necessary to adjust the installation angle of the conveying pipe, the worm 37 is driven to rotate by starting the first motor 36, and the worm 37 is driven to rotate in turn by the worm 37, so as to adjust the pitch angle of the lifting plate 401. It can be freely and flexibly adjusted according to the installation angle of the conveying pipe, which greatly reduces the difficulty of installation.

[0024] The effect achieved by the entire embodiment 2 is that, by setting the guide rod 35, the lifting plate 401 is made to move up and down more stably and less likely to shake. By starting the second motor 403 to drive the threaded rod 404 to rotate, the slider 406 is driven to slide in the slide groove 402, which has the effect of adjusting the horizontal angle of the transport tube, further improving the flexibility and accuracy of the installation of the transport tube.

[0025] Working principle: When using this device to install the delivery pipe of the screw conveyor, the decoration is moved to the top of the delivery pipe through the moving wheel 11, and then the hydraulic rod 34 is started to drive the lifting plate 401 to move downward through the slider 406, the first rotating block 407, the connecting rod 408 and the second rotating block 409 in sequence, so that the lifting ring 410 drops to a suitable position, and the bolts between the limit plate 411 and the lifting ring 410 are screwed to separate the limit plate 411 and the lifting ring 410, and the delivery pipe is placed inside the two lifting rings 410, and then the limit plate 411 is connected to the lifting ring 410 through the bolts, so as to fix the delivery pipe, and then the delivery pipe is suspended by the hydraulic rod 34.
