The support ring is arranged in at least two and parallel to each other. The support ring connecting rod and the at least two support rings are connected together to form a cylindrical support frame. The crane guide rail is arranged on the support frame and parallel to the support ring connecting rod. The crane trolley is provided with a remote controller for controlling the movement and lifting of the crane trolley.

[0067] When the device is installed in a large-diameter pipeline, the plurality of support rings 1 are moved into the pipeline through the plurality of rolling seats 2, the device is lifted and suspended by driving the lifting hooks 5 through the plurality of crane trolleys 4, the installation posture is adjusted, and the device is installed by driving the crane trolleys 4 to deliver the device to the installation position inside the pipeline. It should be noted that after the device is lifted, the two push jacks 608 are moved, the push jacks 608 drive the lifting driven frame 604 to move, the lifting driven frame 604 drives the two tooth plate frames 605 to move, and then the tooth plate frames 605 drive the linkage gear 606 to rotate, the linkage gear 606 rotates on one side of the support ring 1 and drives the rotating lifting frame 602 to rotate, the two rotating lifting frames 602 drive the two lifting transfer shafts 610 to move, and then the two lifting transfer shafts 610 drive the lifting stabilizing frame 601 to rotate, thereby supporting the bottom side of the device and ensuring the stability of the device during installation, avoiding the problem of excessive shaking and hitting the pipeline during hoisting of the device;

[0068] Further, when the push jacks 608 move, the drive plates 712 are driven to move, the drive plates 712 drive the two transfer drive rods 711 to rotate, the two transfer drive rods 711 push the two horizontal push plates 709 to move, the two horizontal push plates 709 slide horizontally in the two horizontal limiting grooves 710, and the two horizontal push plates 709 push the two rotating push-pull rods 703 to rotate, the rotating push-pull rods 703 rotate on the push-pull rotating shaft 706, and the push-pull torsional springs 708 are stressed at the same time, and the rotating push-pull rods 703 drive the horizontal push-pull frame 702 to move through the push-pull shaft 705 when rotating, and the push-pull shaft 705 slides on the push-pull hole 704, so that the horizontal push-pull frame 702 drives the horizontal insertion stabilizing frame 701 to be inserted on the lifting hook 5, and then the lifting hook 5 is raised and limited by the horizontal insertion stabilizing frame 701, further ensuring the stability of hoisting;

[0069] Further, when the lifting stabilizer 601 drives the adapter frame 609 to move upwards, the lifting stabilizer 601 no longer extrudes the two follow-up rotating bases 801, at this time, under the resilience of the two follow-up torsional springs 808, the two support rotating shafts 806 are driven to rotate, so that the support rotating shafts 806 drive the follow-up rotating bases 801 to rotate, the follow-up rotating bases 801 drive the follow-up sliding seats 802 to rotate through the falling buffer rods 803, the follow-up sliding seats 802 slide in the adapter frame 609 through the follow-up sliding shafts 804, at the same time, when the two follow-up rotating bases 801 rotate, the extrusion plates 809 and the locking elastic rods 811 are close to each other, and the extrusion plates 809 extrude the locking elastic rods 811 to retract in the locking elastic grooves 810, and at the same time, the locking springs 812 are forced to contract. It should be noted that when the positions of the locking elastic rods 811 and the locking holes 813 correspond, under the resilience of the locking springs 812, the locking elastic rods 811 are inserted into the locking holes 813, so that the two follow-up rotating bases 801 are locked with each other, at this time, if the equipment falls, it first falls on the lifting stabilizer 601, so that the lifting stabilizer 601 drives the plurality of follow-up sliding seats 802 to move through the adapter frame 609, the follow-up sliding seats 802 move on the follow-up rotating bases 801 through the falling buffer rods 803, and the buffer springs 805 are forced, at this time, under the resilience of the buffer springs 805, the lifting stabilizer 601 is buffered, and at the same time, the equipment is supported through the two follow-up rotating bases 801 which are locked with each other, so as to avoid the problem that the equipment directly falls and damages the pipeline.

[0070] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical solutions and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
