Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe bushings, in particular to a bushing for clamping and protecting nuclear power pipes. Background Art
[0002] A bushing refers to a ring sleeve that acts as a cushion. It is mostly made of soft metal, rubber, nylon and non-metallic polymers. These materials are relatively soft and low in cost. In various harsh working environments, the bushing withstands vibration, friction and corrosion to protect the wrapped parts. The bushing itself is easy to replace after damage, with low cost and good economy.
[0003] In the prior art, nuclear power pipes are a kind of high-precision pipes. Therefore, during the clamping process of nuclear power pipes, bushings are used to protect them to prevent damage to the nuclear power pipes during the clamping process. However, most of the bushings currently used to protect nuclear power pipes are relatively simple and cannot be adjusted in size and length according to the shapes of different nuclear power pipes. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a bushing for clamping and protecting nuclear power pipes, so as to solve the technical problem that the bushing is single and cannot be adjusted in size and length according to the shape of the nuclear power pipes.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bushing for clamping and protecting nuclear power pipes, comprising multiple groups of first bushings and multiple groups of second bushings, inner cavities are opened at both ends of each group of the first bushings and both ends of each group of the second bushings, every two groups of the first bushings are movably connected by shrinkage blocks, every two groups of the second bushings are movably connected by shrinkage blocks, sliding cavities are opened on both sides of the bottom of each group of the first bushings and on one side of the bottom of each group of the second bushings, each group of the first bushings and each group of the second bushings are slidably connected by connecting rods, every two groups of the first bushings are elastically connected by first telescopic cloths, and every two groups of the second bushings are elastically connected by second telescopic cloths.
[0006] By adopting the above technical scheme, the utility model sets multiple groups of connecting rods between multiple groups of first bushings and multiple groups of second bushings. Through multiple groups of first telescopic cloths and second telescopic cloths, the diameter of the cavity inside the bushing can be adjusted. By setting multiple groups of connecting rods between the first bushing and the second bushing and making the multiple groups of connecting rods slide, the length of the overall bushing can be adjusted, thereby solving the technical problem that a single bushing cannot be adjusted according to the size and length of nuclear power pipes.
[0007] Furthermore, each group of the contraction blocks is fixedly connected to a first stopper, and both sides of each group of the connecting rods are fixedly connected to a second stopper.
[0008] By adopting the above technical solution, the moving distance of the shrinking block and the connecting rod can be limited.
[0009] Furthermore, both ends of each group of the first bushings are fixedly connected with a block, and both ends of each group of the second bushings are fixedly connected with a block.
[0010] By adopting the above technical solution, the second stopper can be limited.
[0011] Furthermore, each group of the inner cavities is connected to a first stopper in an arc-shaped sliding manner, and each group of the sliding cavities is connected to a second stopper in a sliding manner.
[0012] By adopting the above technical solution, the shrinking block and the connecting rod can slide.
[0013] Further, each group of the first telescopic cloth and each group of the second telescopic cloth are made of elastic material and play the role of shrinkage bushing.
[0014] By adopting the above technical solution, the first bushing and the second bushing can be expanded and contracted.
[0015] Furthermore, each set of the first bushing and the second bushing has a placement cavity inside, which serves to place nuclear power pipes.
[0016] By adopting the above technical solution, nuclear power pipes can be placed inside the liner.
[0017] In summary, the utility model mainly has the following beneficial effects: the utility model arranges multiple groups of connecting rods between multiple groups of first bushings and multiple groups of second bushings, and the diameter of the cavity inside the bushing can be adjusted through multiple groups of first telescopic cloths and second telescopic cloths. By arranging multiple groups of connecting rods between the first bushings and the second bushings and making the multiple groups of connecting rods slide, the length of the overall bushing can be adjusted, thereby solving the technical problem that a single bushing cannot be adjusted according to the size and length of nuclear power pipes.

[0027] When in use, if the diameter of the nuclear power pipe is large, the first bushing 1 and the second bushing 2 can be pulled outward, and the shrinkage block 6 located inside the first bushing 1 and the second bushing 2 will also slide in the inner cavity 5 accordingly. When the first stoppers 7 at both ends of the shrinkage block 6 are in contact with the stoppers 11 at both ends of the bushing, the bushing diameter will reach the maximum diameter;
[0028] Under the elastic force of the multiple sets of first telescopic cloths 9 and second telescopic cloths 10, the multiple sets of first bushings 1 and second bushings 2 will closely fit the nuclear power pipes to be clamped, thereby effectively protecting the nuclear power pipes;
[0029] If the nuclear power pipe is longer, it can be placed in the placement cavity 12, and the two sets of second bushings 2 can be pulled to drive the connecting rod 3 to slide inside the sliding cavity 4. When the second stoppers 8 on both sides of the connecting rod 3 are in contact with the inner wall of the bushing, the maximum length will be reached.
[0030] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Each group of shrinkage blocks 6 is fixedly connected to a first stopper 7, and each group of connecting rods 3 are fixedly connected to second stoppers 8 on both sides. By setting the above structure, the utility model can limit the moving distance of the shrinkage blocks 6 and the connecting rods 3.
[0031] See also Figure 1 and Figure 2 Both ends of each group of first bushings 1 are fixedly connected with blocks 11, and both ends of each group of second bushings 2 are fixedly connected with blocks 11. By setting the above structure, the utility model can limit the second stopper 8.
[0032] See also Figure 2 , Figure 3 and Figure 5 Each group of inner cavities 5 is connected to a first stopper 7 in an arc-shaped sliding manner, and each group of sliding cavities 4 is connected to a second stopper 8 in a sliding manner.

[0036] Under the elastic force of the multiple sets of first telescopic cloths 9 and second telescopic cloths 10, the multiple sets of first bushings 1 and second bushings 2 will closely fit the nuclear power pipes to be clamped, thereby effectively protecting the nuclear power pipes;
[0037] If the nuclear power pipe is long, the nuclear power pipe can be placed in the placement cavity 12, and the two sets of second bushings 2 are pulled to drive the connecting rod 3 to slide inside the sliding cavity 4. When the second stoppers 8 on both sides of the connecting rod 3 are in contact with the inner wall of the bushing, the maximum length will be reached.
[0038] In summary, multiple groups of connecting rods 3 and telescopic cloths are arranged between multiple groups of first bushings 1 and multiple groups of second bushings 2, so that the diameter of the placement cavity 12 inside the bushing can be adjusted, and multiple groups of connecting rods 3 are arranged between the first bushings 1 and the second bushings 2, so that the length of the entire bushing can be adjusted;
[0039] Thereby, the technical problem that a single bushing cannot be adjusted according to the size and length of nuclear power pipes can be solved.
