[0025] When the telescopic floating FRP pipe lifting device of the utility model lifts the FRP pipe, the clamping range between the left clamping arm 3 and the right clamping arm 4 is adjusted according to the length of the FRP pipe. First, the left clamping arm 3 and the right clamping arm 4 are driven to slide on the movable crossbeam 2 by the driving assembly to achieve the clamping range adjustment. After the adjustment, the FRP pipe is placed between the floating clamping assemblies 5 of the left clamping arm 3 and the right clamping arm 4. Then, the auxiliary support mechanism 6 is used to first perform auxiliary support on the FRP pipe. Then, the left clamping arm 3 and the right clamping arm 4 are controlled in reverse to move so that the floating clamping assembly 5 extends into both ends of the FRP pipe. Then, the first cylinder 502 is started to drive the arc plate 504 at one end of the support rod 503 to support, clamp and fix the FRP pipe from the inner sides of both ends of the FRP pipe.

[0026] The driving assembly includes a driving shaft 8, a driving gear 9 and a rack 10. The driving shaft 8 is rotatably provided in the middle of the moving crossbeam 2, and the driving gear 9 is installed on the driving shaft 8. The bottom of the left clamping arm 3 and the top of the right clamping arm 4 are both provided with racks 10, and the driving gear 9 is meshed with the rack 10. In the utility model, the driving shaft 8 is driven by a driving motor.

After the movable arc seat 603 slides into position, the limiting bolt 605 is connected to the threaded fixing hole 604 to fix the position state between the base 602 and the movable arc seat 603. In the initial state, the movable arc seat 603 is controlled to overlap with the arc surface on the inner side of the base 602, so that one side of the auxiliary support mechanism 6 is completely exposed, so that the FRP pipe can horizontally enter the support range of the auxiliary support mechanism 6, and then the movable arc seat 603 is slid so that the FRP pipe is supported by the base 602 and the movable arc seat 603. At this time, since the enclosure diameter formed by the base 602 and the movable arc seat 603 is larger than the diameter of the FRP pipe, in order to ensure that the FRP pipe is concentric with the clamping center of the floating clamping assembly 5, the second cylinder 601 can be used to adjust the position of the FRP pipe fixed by the auxiliary support mechanism 6 to make it concentric with the clamping center of the floating clamping assembly 5.

[0030] The inner arc surface of the movable arc seat 603 is rotatably provided with a rubber guide roller 606, and the rubber guide roller 606 is provided with multiple groups.

With the assistance of the rubber guide roller 606, the FRP pipe can be rotated, and then after being rotated to a suitable position, the arc plate 504 of the floating clamping assembly 5 can be used to clamp and fix the inner wall of the FRP pipe again.

[0031] The utility model sets a lifting device to drive the moving crossbeam 2 to rise and fall for lifting.

The lifting process of the whole lifting device has high stability. The floating clamping assembly 5 arranged on the left clamping arm 3 and the right clamping arm 4 of the utility model cooperates with the auxiliary supporting mechanism 6 to realize the rotation of the glass fiber reinforced plastic pipe after clamping and positioning, so as to process multiple positions of the glass fiber reinforced plastic pipe, which can improve the convenience and flexibility of the use of the structure of the utility model.
