Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and more specifically, to an anti-expansion auxiliary device for replacing pipeline components. Background Technology

[0002] In current pipeline component replacement operations, a series of problems caused by thermal expansion and contraction severely restrict installation efficiency and quality. In the high temperatures of summer, pipelines expand due to heat, and after component removal, the pipelines at both ends extend outwards, reducing the reserved installation space. Even if the component size is suitable, it is difficult to directly embed and install it. It is often necessary to use heavy equipment such as excavators to forcibly bend the pipeline to widen the gap. This process not only causes potential damage to the pipeline structure, but also poses a risk of pipeline deformation and rupture due to uneven external force. In the low-temperature environment of winter, the pipeline shrinks due to cold, resulting in excessive gaps at both ends. Bolts cannot be properly tightened to connect components and pipelines. Similarly, excavators are needed to straighten and correct the pipeline. Repeated external force operations are not only time-consuming and labor-intensive, increasing labor and equipment costs, but may also delay the project schedule and reduce the timeliness and reliability of maintenance operations. Therefore, improvements and optimizations are needed. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an anti-expansion auxiliary device for replacing pipeline components, which has the advantage of reducing expansion and contraction problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-expansion auxiliary device for replacing pipeline components, comprising two rigid supports. Upper lead screws are slidably installed on both sides of the two rigid supports, with both ends of the upper lead screws penetrating the interior of the two rigid supports. Lower lead screws are slidably installed on both sides of the rigid supports directly below the upper lead screws, with both ends of the lower lead screws penetrating the interior of the two rigid supports. A sliding groove is provided at the top of the rigid supports. An anti-expansion auxiliary component is fixedly installed inside the sliding groove. The anti-expansion auxiliary component includes a first lead screw adjusting nut fixedly installed inside the sliding groove, with the first lead screw adjusting nut penetrating the interior of the rigid support. A lead screw is threadedly connected inside the first lead screw adjusting nut. An upper clamp is rotatably installed at the other end of the lead screw. Bolts are threadedly connected to both sides of the upper clamp, with both ends of the bolts penetrating the interior of the upper clamp. Lower clamps are movably installed on the outer surfaces of the two bolts. Nuts are threaded onto the outer surfaces of the bolts and located below the lower clamps.

[0005] As a preferred technical solution of this utility model, flexible components are fixedly connected to the inner sides of both the upper and lower clamps. The flexible components include springs fixedly connected to the inner sides of the upper and lower clamps, and a flexible pad is fixedly connected to the other end of the springs. The flexible pad is arc-shaped.

[0006] As a preferred technical solution of this utility model, the first lead screw adjusting nut is internally threaded with a lead screw, and both ends of the lead screw pass through the inside of the first lead screw adjusting nut.

[0007] As a preferred technical solution of this utility model, the rigid bracket has limit grooves on both sides of its inner side, and limit connecting rods are slidably installed on the inner side of each limit groove, with the other end of each limit connecting rod being fixedly connected to the outer surface of the upper clamp.

[0008] As a preferred technical solution of this utility model, the outer surfaces of the upper lead screw and the lower lead screw are threaded with two sets of second lead screw adjusting nuts, and each set of second lead screw adjusting nuts has two nuts located on the left and right sides of the rigid bracket respectively.

[0009] As a preferred embodiment of this utility model, the rigid support is C-shaped and does not contact the pipeline or components.

[0010] As a preferred embodiment of this utility model, the upper clamp and the lower clamp are semi-circular arc-shaped, and the upper clamp and the lower clamp are of equal size.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses components that pass through upper and lower clamps on both sides, allowing the lower clamp to fit against the component and achieve reverse self-locking by rotating the nut. This fixing method is highly reliable and can prevent the component from loosening. Secondly, the upper and lower clamps encircle and clamp the pipeline, which can effectively reduce the amount of expansion and contraction caused by thermal expansion and contraction, ensuring the stability of the pipeline system and reducing damage to the pipeline. Finally, the entire replacement process is convenient, efficient, time-saving, and labor-saving, which can improve work efficiency, reduce labor costs, reduce labor intensity, improve the quality and speed of pipeline maintenance work, and extend the service life of the pipeline.

[0013] 2. In this utility model, when the pipeline passes through the upper and lower clamps, it first contacts the flexible pads on both sides. The lower clamp fits the pipeline, making the flexible pads in close contact with the pipeline, which can enhance the pipeline fixing effect and prevent it from loosening and shifting during operation. After the pipeline is disassembled due to damage, the spring force recovers under seasonal temperature changes, causing the flexible pads to flexibly clamp and fit, which can effectively buffer the small deformation caused by thermal expansion and contraction, reduce stress damage to the pipeline, and the flexible clamping and fitting makes the pipeline installation more flexible, reduces the installation difficulty, and improves work efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides an anti-expansion auxiliary device for replacing pipeline components, including two rigid supports 1. Upper lead screws 5 are slidably installed on both sides of the interior of the two rigid supports 1, with both ends of the upper lead screws 5 passing through the interior of the two rigid supports 1. Lower lead screws 6 are slidably installed on both sides of the interior of the rigid supports 1 directly below the upper lead screws 5, with both ends of the lower lead screws 6 passing through the interior of the two rigid supports 1. A sliding groove 2 is provided at the top of the rigid support 1, and an anti-expansion auxiliary component 3 is fixedly installed inside the sliding groove 2. The anti-expansion auxiliary component 3 includes a fixed... A first lead screw adjusting nut 301 is fixedly installed inside the sliding groove 2 and passes through the rigid bracket 1. A lead screw 302 is threadedly connected inside the first lead screw adjusting nut 301. An upper clamp 303 is rotatably installed at the other end of the lead screw 302. Bolts 305 are threadedly connected to both sides of the upper clamp 303, and both ends of the bolts 305 pass through the upper clamp 303. A lower clamp 304 is movably installed on the outer surface of the two bolts 305. A nut 306 is threaded onto the outer surface of the bolts 305 and is located below the lower clamp 304.

[0022] When it is necessary to replace a damaged pipe component, first pass the damaged pipe component between the upper clamp 303 and the lower clamp 304 on one side, and then pass it between the upper clamp 303 and the lower clamp 304 on the other side. Then, use external force to make the lower clamp 304 fit against the damaged pipe component. Then, rotate the nut 306 to make it tightly contact the outer surface of the lower clamp 304. Since the nut 306 is threaded on the outer surface of the bolt 305, it can self-lock in the reverse direction, thereby fixing the damaged pipe component. After the damaged pipe component is disassembled, the upper clamp 303 and the lower clamp 304 clamp the pipes at both ends of the damaged pipe component.

[0023] First, the component passes through the upper clamp 303 and lower clamp 304 on both sides, allowing the lower clamp 304 to fit against the component and the nut 306 to be rotated to achieve reverse self-locking. This fixing method is very reliable and can prevent the component from loosening. Second, the upper clamp 303 and lower clamp 304 encircle and clamp the pipeline, which can effectively reduce the amount of expansion and contraction caused by thermal expansion and contraction, ensure the stability of the pipeline system, and reduce damage to the pipeline. Finally, the entire replacement process is convenient, efficient, time-saving, and labor-saving, which can improve work efficiency, reduce labor costs, reduce labor intensity, improve the quality and speed of pipeline maintenance work, and extend the service life of the pipeline.

[0024] The upper clamp 303 and the lower clamp 304 are both fixedly connected to the inner side of a flexible component 4. The flexible component 4 includes a spring 401 fixedly connected to the inner side of the upper clamp 303 and the lower clamp 304. The other end of the spring 401 is fixedly connected to a flexible pad 402, and the flexible pad 402 is arc-shaped.

[0025] When the pipeline passes between the upper clamp 303 and the lower clamp 304, it will first contact the flexible pads 402 on both sides. When the lower clamp 304 gradually fits into the pipeline, the two flexible pads 402 will first fit into the pipeline. When the damaged parts of the pipeline are disassembled, the pipeline will undergo slight deformation due to the large temperature changes of the seasons and the effects of thermal expansion and contraction. At the same time, the elasticity of the spring 401 will cause the flexible pads 402 to adapt to the changes and perform flexible clamping and fitting.

[0026] When the pipeline passes through the upper clamp 303 and the lower clamp 304, it first contacts the flexible pads 402 on both sides. The lower clamp 304 fits the pipeline so that the flexible pads 402 are in close contact with the pipeline, which can enhance the pipeline fixing effect and prevent it from loosening and shifting during operation. After the pipeline is disassembled due to damage, under seasonal temperature changes, the elasticity of the spring 401 will restore and drive the flexible pads 402 to flexibly clamp and fit, which can effectively buffer the small deformation caused by thermal expansion and contraction, reduce stress damage to the pipeline, and the flexible clamping and fitting makes the pipeline installation more flexible, reduces the installation difficulty, and improves work efficiency.

[0027] The first lead screw adjusting nut 301 is internally threaded with a lead screw 302, and both ends of the lead screw 302 pass through the inside of the first lead screw adjusting nut 301.

[0028] By rotating the lead screw 302, which is threadedly connected to the first lead screw adjusting nut 301 and fixedly installed inside the sliding groove 2, the lead screw 302 can move up and down. At the same time, since the lead screw 302 is rotatably connected to the upper clamp 303, the upper clamp 303 does not rotate relative to the lead screw 302, so the upper clamp 303 can only move up and down. When the upper clamp 303 moves up and down, it will drive the lower clamp 304 to move synchronously, thus adapting to pipelines on different terrains.

[0029] Among them, the rigid bracket 1 has limit grooves 307 on both sides of its inner side, and limit connecting rods 308 are slidably installed on the inner side of the limit grooves 307, and the other end of the limit connecting rods 308 is fixedly connected to the outer surface of the upper clamp 303.

[0030] The other end of the limiting link 308 is fixedly connected to the outer surface of the upper clamp 303, which can limit the upper clamp 303 and prevent the upper clamp 303 from rotating when the screw 302 rotates and drives the upper clamp 303 to move up and down for adjustment.

[0031] The upper lead screw 5 and the lower lead screw 6 are threaded with two sets of second lead screw adjusting nuts 7 on their outer surfaces, and each set of second lead screw adjusting nuts 7 has two nuts located on the left and right sides of the rigid bracket 1 respectively.

[0032] Each set of second lead screw adjusting nuts 7 has two nuts located on the left and right sides of the rigid bracket 1, which facilitates the later adjustment of the position of the rigid bracket 1.

[0033] Among them, the rigid support 1 is C-shaped and does not contact the pipeline or components.

[0034] The rigid support 1 is C-shaped and does not contact the pipelines or components, which can provide stable support for the entire device without affecting the replacement of pipelines.

[0035] The upper clamp 303 and the lower clamp 304 are semi-circular arcs, and the upper clamp 303 and the lower clamp 304 are of equal size.

[0036] The upper clamp 303 and the lower clamp 304 are semi-circular arc-shaped, and the upper clamp 303 and the lower clamp 304 are of equal size, which makes it easy for the upper clamp 303 and the lower clamp 304 to fit the pipeline and clamp it stably.

[0037] Working principle and usage process of this utility model:

[0038] When it is necessary to replace a damaged pipe component, first pass the damaged pipe component between the upper clamp 303 and the lower clamp 304 on one side, and then pass it between the upper clamp 303 and the lower clamp 304 on the other side. Then, use external force to make the lower clamp 304 fit against the damaged pipe component. Then, rotate the nut 306 to make it tightly contact the outer surface of the lower clamp 304. Since the nut 306 is threaded on the outer surface of the bolt 305, it can self-lock in the reverse direction, thereby fixing the damaged pipe component. After the damaged pipe component is disassembled, the upper clamp 303 and the lower clamp 304 clamp the pipes at both ends of the damaged pipe component.

[0039] When the pipeline passes between the upper clamp 303 and the lower clamp 304, it will first contact the flexible pads 402 on both sides. When the lower clamp 304 gradually fits into the pipeline, the two flexible pads 402 will first fit into the pipeline. When the damaged parts of the pipeline are disassembled, the pipeline will undergo slight deformation due to the large temperature changes of the seasons and the effects of thermal expansion and contraction. At the same time, the elasticity of the spring 401 will cause the flexible pads 402 to adapt to the changes and perform flexible clamping and fitting.
