DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 - Figure 4As shown, the present invention is an anti-falling glass fiber reinforced plastic pipe lifting device, comprising two sets of lifting components 1, a connecting component 2 is arranged between the opposite sides of the two sets of lifting components 1, the lifting component 1 comprises a lower base plate 11 and an upper hanging plate 12, the lower base plate 11 and the upper hanging plate 12 are provided with arc grooves for positioning the glass fiber reinforced plastic pipe on the opposite sides, the top of the upper hanging plate 12 is fixedly connected with a servo motor 13 on both sides, the servo motor 13 is electrically connected to an external power supply and can realize forward and reverse rotation, the top of the upper hanging plate 12 and located directly below the servo motor 13 is penetrated with a through hole 15, the output end of the servo motor 13 is fixedly connected with a threaded rod 16, and the top of the lower base plate 11 is fixedly connected with a connecting sleeve on both sides 14, a threaded hole 17 is provided at the top of the connecting sleeve 14, and the outer surface of the threaded rod 16 is threadedly connected to the inner surface of the threaded hole 17. By setting two sets of lifting components 1, the arc grooves on the lower base plate 11 and the upper hanging plate 12 in the lifting components 1 can limit the glass fiber reinforced plastic pipe, and then through the matching relationship between the threaded rod 16 and the threaded hole 17 on the servo motor 13, when the threaded rod 16 rotates, the lower base plate 11 and the upper hanging plate 12 can move to a relatively close side, so that the glass fiber reinforced plastic pipe can be clamped. By using this structure to lift the glass fiber reinforced plastic pipe, not only can multiple glass fiber reinforced plastic pipes be lifted at the same time, but the lifting is also more stable, which further improves its work efficiency and prevents the glass fiber reinforced plastic pipe from falling off.

[0025] The connecting component 2 includes a threaded sleeve 21 located on the opposite side of the two upper hanging plates 12, and a bidirectional threaded rod 25 is threadedly connected between the inner surfaces of the two threaded sleeves 21. The rotation of the bidirectional threaded rod 25 can push the two upper hanging plates 12 to move to the relatively close side or to the relatively far side. The outer surface of the bidirectional threaded rod 25 is fixedly connected to a rotating block 26, and the outer surface of the rotating block 26 is provided with a plurality of convex strips for increasing friction. The opposite sides of the two lower base plates 11 are fixedly connected to sliding sleeves 22, and the inner surfaces of the two sliding sleeves 22 are slidably connected to sliding blocks 24. A sliding rod 23 is fixedly connected between the opposite sides of the two sliding blocks 24. When the glass fiber reinforced plastic pipe is long, the two hoisting components 1 can be moved to the relatively far side by rotating the bidirectional threaded rod 25, and the sliding block 24 slides on the inner surfaces of the two sliding sleeves 22 to the relatively close side, thereby improving the supporting effect of the hoisting component 1 on the glass fiber reinforced plastic pipe.

[0026] See also Figure 3As shown, a placement groove 3 is opened inside the lower base plate 11, and a driving motor 4 is fixedly connected to the inner surface of the placement groove 3. The driving motor 4 is electrically connected to an external power supply and can realize forward and reverse rotation. This is the prior art and will not be described in detail here. A driving shaft 5 is fixedly connected to the output end of the driving motor 4. A placement groove 6 is opened on one side of the lower base plate 11 and on the surface of the arc groove. A roller 7 is fixedly connected to the outer surface of the driving shaft 5 and located inside the placement groove 6. The outer surface of the roller 7 is set to an arc shape. When the driving motor 4 rotates, it can drive the roller 7 to rotate.

[0027] See also Figure 4 As shown, a tightening assembly 8 for tightening the FRP pipe is obliquely arranged on one side of the upper hanging plate 12 and on both sides of the arc groove. The tightening assembly 8 includes a fixed sleeve 83 located on the upper hanging plate 12, and a spring 84 is fixedly connected to one side of the inner wall of the fixed sleeve 83. One end of the spring 84 is fixedly connected to a connecting rod 82, and one end of the connecting rod 82 is connected to a clamping wheel 81. By arranging a driving motor 4 in the upper hanging plate 12, the roller 7 on the driving shaft 5 is driven to rotate in coordination with the rotation of the driving motor 4, and the FRP pipe is squeezed by the clamping wheel 81, so that the FRP pipe can move to the inside of the equipment by itself, which can reduce the labor intensity of the staff and prevent the FRP pipe from shaking during lifting.

[0028] A rolling groove is provided at the top of the upper hanging plate 12, and a ball 9 is rollingly connected to the inner surface of the rolling groove. A lifting ring 10 is fixedly connected to the outer surface of the ball 9. The lifting ring 10 is suspended by an external hook, and when the distance between the two lifting components 1 changes, the ball 9 on the lifting ring 10 rolls on the inner surface of the rolling groove.

[0029] Working principle of the present invention:

[0030] First, the lifting ring 10 is connected to the external hook, and then the lifting assembly 1 is moved to the FRP pipe by the external lifting equipment, so that the FRP pipe is located between the lower base plate 11 and the upper hanging plate 12. At this time, the servo motor 13 is started to rotate, thereby driving the threaded rod 16 in the through hole 15 to rotate. The threaded connection relationship between the threaded rod 16 and the threaded hole 17 is used to move the lower base plate 11 and the upper hanging plate 12 to a relatively close side, so that the FRP pipe is in contact with the inner surface of the arc groove. At the same time, the spring 84 of the fixing sleeve 83 is in a compressed state, and the fixing sleeve 83 is used to connect the connecting The rod 82 applies a thrust, so that the clamping wheel 81 and the roller 7 are in contact with the surface of the FRP pipe. At this time, the drive motor 4 is started to rotate, thereby driving the roller 7 on the drive shaft 5 to rotate. At this time, the FRP pipe will move between the two hanging components 1, so as to position the FRP pipe. When the FRP pipe is long, the rotating block 26 can be rotated to make the bidirectional threaded rod 25 rotate on the inner surfaces of the two threaded sleeves 21, so as to push the two hanging components 1 to the relatively far side, and the sliding block 24 on the sliding rod 23 also slides on the inner surface of the sliding sleeve 22.

[0031] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
