Description

Technical Field

[0001] This utility model relates to the field of pipeline equipment technology, specifically to a pipeline centering support. Background Technology

[0002] In municipal engineering, industrial pipeline installation, and water conservancy construction, the cutting, welding, and flange connection processes of pipelines require extremely high positioning accuracy and versatility. During pipeline processing, it is essential to ensure that the pipeline remains stable radially, axially, and vertically to avoid quality problems such as misalignment of interfaces and tilting of cut surfaces caused by positioning deviations.

[0003] Various pipe centering supports have emerged in the prior art, such as the pipe centering support in utility model patent CN223537101U, which achieves pipe positioning through the cooperation of support structure and clamping structure. However, because the installation position of its support rollers is fixed, the spacing cannot be adjusted.

[0004] When processing pipes with large diameters, the fixed-gap support rollers can only contact the top area of ​​the pipe's outer wall, resulting in insufficient support points and causing the pipe to wobble during processing. When processing pipes with small diameters, the support rollers are too far apart, failing to provide effective lateral restraint, causing the pipe to easily shift horizontally or even detach from its support position. This adaptability deficiency limits the use of existing supports to pipes within a specific diameter range, leading to poor versatility and insufficient positioning stability, severely impacting processing accuracy and operational efficiency. Summary of the Invention

[0005] The technical problem to be solved by this utility model is how to solve the problem of fixed spacing and poor adaptability of the support rollers of the pipeline centering support in the prior art.

[0006] The technical solution adopted by this utility model is as follows: a pipe centering support includes a frame, a base connected to the frame, an adjustment cavity on the base, a support rod slider and an adjustment rod inside the adjustment cavity, a support rod slider rotatably connected to a support rod, a support roller on the support rod, a rotating component rotatably connected to the end of the support rod away from the support rod slider, the rotating component slidably connected to the adjustment rod, and an adjustment knob on the adjustment rod that abuts against the rotating component. By turning the adjustment knob, the rotating component can be driven to slide along the adjustment rod, thereby causing the support rod to rotate around the support rod slider to adjust the spacing of the support rollers.

[0007] The above structure has the following beneficial effects: By incorporating an adjustment cavity in the base, along with a support rod slider, adjustment rod, rotating component, and adjustment knob, the spacing between the support rollers can be actively adjusted. Simply turning the adjustment knob drives the rotating component to slide along the adjustment rod, which in turn causes the support rod to rotate around the support rod slider, directly solving the problem of fixed support roller spacing in existing technologies. This structure can adapt to pipes of different diameters, eliminating the need to replace supports separately for different pipes, significantly improving the versatility of the support, reducing equipment procurement and replacement costs, and simplifying the support commissioning process during pipe installation.

[0008] Preferably, the top of the frame is provided with a sliding through hole, and a sliding rod slider is slidably connected to the inner wall of the top of the frame. The sliding rod slider is connected to the sliding rod, and the sliding rod slider is provided with a sliding rod locking knob passing through the sliding through hole. The sliding rod locking knob is used to lock the relative position of the sliding rod slider and the frame.

[0009] By incorporating a sliding through-hole, a sliding rod slider, and a sliding rod locking knob on the top of the frame, flexible adjustment of the relative position of the sliding rod to the frame is achieved. The position of the sliding rod can be adjusted by sliding it according to actual conditions, and then locked in place using the sliding rod locking knob. This satisfies the lateral position adaptation requirements of different installation scenarios while ensuring the stability of the sliding rod after positioning, preventing pipe support misalignment due to sliding rod displacement during use.

[0010] Preferably, one of the sliding rods is provided with two bases, the bottom of the bases is slidably connected to the sliding rod, the sliding rod is provided with a limiting through hole, a base locking member is provided between the sliding rod and the base, and the base locking member is connected to a base locking knob.

[0011] By installing two sliding bases on a sliding rod, along with limiting through holes, base locking components, and base locking knobs, the distance between the two bases is adjustable. The distance between the two bases can be adjusted according to the length of the pipe or the key points requiring support, allowing the bracket to precisely support different length sections of the pipe and preventing support points from being too close or too far apart due to a fixed base distance. Simultaneously, the cooperation between the base locking components and the limiting through holes ensures that the bases are not easily loosened after being locked in position, improving the stability of the pipe support.

[0012] Preferably, the tops of the two bases are respectively connected to a first pressing seat and a second pressing seat. The first pressing seat is provided with a connecting rod, and a connecting member is provided between the first pressing seat and the second pressing seat. The connecting member is engaged with the connecting rod, and an adjusting rod is rotatably connected to the end of the connecting member away from the connecting rod. The adjusting rod is connected to the second pressing seat.

[0013] By setting a first clamping seat and a second clamping seat on the top of the two bases, and cooperating with a connecting rod, a snap-fit ​​connector, and a rotatably connected adjusting rod, the two clamping seats can be detachably connected and their spacing can be adjusted. That is, the relative distance between the two clamping seats can be adjusted according to the pipe diameter, so that the clamping structure can fit the outer wall of pipes of different specifications. On the other hand, the snap-fit ​​connector facilitates the quick assembly and disassembly of the clamping seats, while the rotatably connected adjusting rod reduces the operating resistance when adjusting the spacing, improves the convenience of bracket assembly and debugging, and reduces installation time.

[0014] Preferably, both the first and second clamping seats are connected to clamping assemblies. Each clamping assembly includes a clamping rod, which is threadedly connected to the first and second clamping seats. The bottom of the clamping rod is provided with a rotating end, which is rotatably connected to a clamping element. A clamping element locking knob is fixedly connected to the end of the clamping rod away from the clamping element.

[0015] By setting up a clamping assembly consisting of a clamping rod, a rotating end, a clamping element, and a clamping element locking knob, and threading the clamping rod to the clamping seat, the extension length of the clamping rod can be precisely adjusted by turning the clamping element locking knob, thereby controlling the clamping force of the clamping element on the pipeline. This can prevent the pipeline from shaking during the support process due to insufficient clamping force, and also prevent damage to the outer wall of the pipeline, such as deformation and scratches, due to excessive clamping force. At the same time, the clamping element is connected to the clamping rod through the rotating end, which can adaptively adjust the fitting angle according to the curvature of the outer wall of the pipeline, improving the fit between the clamping structure and the pipeline and enhancing the centering effect.

[0016] Preferably, the adjustment cavity is provided with an adjustment through hole, and the support rod slider is provided with a support rod locking knob. The support rod locking knob passes through the adjustment through hole and is threadedly connected to the support rod slider. Tightening the support rod locking knob can lock the relative position of the support rod slider and the adjustment cavity.

[0017] By setting an adjustment through hole in the adjustment cavity and cooperating with the support rod locking knob on the support rod slider, the position of the support rod slider in the adjustment cavity is locked. After adjusting the support roller spacing, the support rod locking knob can be turned to fix the support rod slider in the adjustment cavity. This prevents the support rod slider from accidentally sliding due to factors such as pipe vibration or external force during the use of the bracket, which would cause the support roller spacing to deviate. The setting of the support rod locking knob further ensures the stability of the support roller position and improves the reliability of the bracket in supporting the pipe.

[0018] Preferably, the adjusting rod is horizontally disposed in the adjusting cavity, one end of the adjusting rod is fixedly connected to the inner wall of the adjusting cavity, and the rotating component is provided with a sliding hole adapted to the adjusting rod, and the rotating component slides with the adjusting rod through the sliding hole.

[0019] By horizontally setting the adjusting rod inside the adjusting cavity and fixing one end to the cavity wall, and simultaneously providing a sliding hole on the rotating component that matches the adjusting rod, on the one hand, the horizontally set adjusting rod ensures that the rotating component slides smoothly along a straight line, avoiding the rotating component from getting stuck or the adjustment accuracy from decreasing due to the tilt of the adjusting rod; on the other hand, the matching cooperation between the sliding hole and the adjusting rod reduces the frictional resistance when the rotating component slides, making the adjustment operation of the support roller spacing smoother, while ensuring the accuracy of the sliding trajectory of the rotating component, improving the accuracy of the spacing adjustment, and ensuring that the support roller can accurately fit the outer wall of the pipe.

[0020] Preferably, an elastic element is sleeved on the adjusting rod, with one end of the elastic element abutting against the inner wall of the adjusting cavity and the other end abutting against the rotating component. The adjusting knob is threadedly connected to the adjusting rod, and the rotating component can be pushed to compress or release the elastic element by turning the adjusting knob.

[0021] By fitting an elastic element onto the adjusting rod, with both ends of the elastic element abutting against the inner wall of the adjusting cavity and the rotating component respectively, and cooperating with the adjusting knob threadedly connected to the adjusting rod, the expansion and contraction of the elastic element during spacing adjustment prevents excessive turning force of the adjusting knob from causing rigid collision damage to the rotating component or support rod. Simultaneously, during pipeline use, the elastic element absorbs minor vibrations, reducing the impact of vibrations on the support structure. Furthermore, the cooperation between the adjusting knob and the elastic element makes the sliding of the rotating component smoother, preventing large-scale movement during spacing adjustment, improving operational safety and adjustment accuracy, and further optimizing the fit of the support roller spacing.

Detailed Implementation

[0027] The following will be combined with the appendix Figure 1-3 The technical solution of this utility model is clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example The following description, in conjunction with specific embodiments, provides further details. Figure 1-3As shown, this embodiment is a pipe centering support, including a frame 10. A sliding rod slider 14 is slidably connected to the inner wall of the top of the frame 10. A sliding through hole 12 is provided in the top of the frame 10. A sliding rod 11 is fixedly connected to the sliding rod slider 14, and a sliding rod locking knob 13 is provided on the sliding rod slider 14, passing through the sliding through hole 12. Loosening the sliding rod locking knob 13 can push the sliding rod slider 14 to slide along the inner wall of the top of the frame 10, thereby adjusting the position of the sliding rod 11. Tightening the knob can lock the sliding rod slider 14 and the frame 10. Regarding the position: Two bases 20 are slidably connected to a sliding rod 11. A limiting through hole 111 is provided on the sliding rod 11. The sliding rod 11 and the bases 20 are connected and locked via a base locking member 21 passing through the limiting through hole 111 and a base locking knob 22. When the base locking knob 22 is loosened, the distance between the two bases 20 can be adjusted along the sliding rod 11. Tightening it fixes the position of the bases 20. Each base 20 is provided with an adjustment cavity 23, which contains a support rod slider 232 and a horizontally arranged adjustment rod 236. One end of the adjusting rod 236 is fixedly connected to the inner wall of the adjusting cavity 23. An adjusting through hole 231 is correspondingly provided on the side wall of the adjusting cavity 23. A support rod locking knob 233 is provided on the support rod slider 232, passing through the adjusting through hole 231 and threadedly connected to it. A support rod 234 is rotatably connected to the support rod slider 232. A support roller 2341 is rotatably connected to the central column of the support rod 234. A rotating component 235 is connected to the end of the support rod 234 away from the support rod slider 232. A sliding hole is provided on the rotating component 235, and the rotating component 235 is connected to the adjusting rod 236 through this sliding hole. The adjusting rod 236 is fitted with an elastic element 237, which is a compression spring. The two ends of the elastic element 237 abut against the inner wall of the adjusting cavity 23 and the rotating part 235, respectively. An adjusting knob 238 is also threaded onto the adjusting rod 236. The adjusting knob 238 abuts against the rotating part 235. When the adjusting knob 238 is turned, the rotating part 235 can be moved and the support rod 234 can be rotated to adjust the distance between the support rollers 2341. After the adjustment is completed, the support rod locking knob 233 can be tightened to lock the position.

[0030] The tops of the two bases 20 are respectively fixedly connected to a first clamping seat 24 and a second clamping seat 25, and rectangular through holes 26 for avoiding pipe fittings are opened on both the first clamping seat 24 and the second clamping seat 25. A connecting rod 241 is provided on the first clamping seat 24. The first clamping seat 24 and the second clamping seat 25 are connected by a connector 27. One end of the connector 27 is snapped into the connecting rod 241, and the other end is rotatably connected to an adjusting rod 271 that is threaded to the second clamping seat 25. The clamping seats can be quickly assembled by snapping into the connector 27, and the distance between the first clamping seat 24 and the second clamping seat 25 can be adjusted by rotating the adjusting rod 271. Both the first clamping seat 24 and the second clamping seat 25 are provided with clamping components 28. The clamping components 28 include a clamping rod 281 that is threadedly connected to the clamping seat. The bottom of the clamping rod 281 is provided with a rotating end 2811. A clamping element 282 is rotatably connected to the rotating end 2811. A clamping element locking knob 283 is connected to the top of the clamping rod 281. Turning the knob can drive the clamping rod 281 to move to adjust the clamping force of the clamping element 282. At the same time, the clamping element 282 can adaptively fit against the outer wall of the pipe through the rotating end 2811.

[0031] Working principle: In use, first loosen the support rod locking knob 233 to release the fixed constraint of the support rod slider 232 in the adjustment cavity 23; when turning the adjustment knob 238, its threaded engagement with the adjustment rod 236 will drive it to move axially along the adjustment rod 236, thereby pushing the rotating part 235 to slide along the adjustment rod 236. During this process, the elastic element 237 will extend and retract synchronously with the rotating part 235. The sliding of the rotating part 235 will cause the support rod 234 to deflect around the axis of the support rod slider 232, changing the opening angle of the support roller 2341 to accurately match the target pipe diameter; after the spacing is matched, tighten the support rod locking knob 233 to lock the position of the support rod slider 232 through the thread force to ensure the stability of the support roller 2341.

[0032] Loosen the sliding rod locking knob 13 to release the friction between the sliding rod slider 14 and the frame 10, allowing the sliding rod 11 to be pushed along the sliding through hole 12 to adjust its lateral position to match the pipe installation path; at the same time, loosen the base locking knob 22, allowing the base 20 to move along the sliding rod 11 to adjust the support spacing according to the pipe length or key points such as the interface; after adjustment, tighten both knobs to fix the position of the sliding rod 11 and the base 20 through locking force.

[0033] The pipe is initially positioned on the support roller 2341. Then, the connector 27 is inserted into the connecting rod 241 of the first clamping seat 24. The second clamping seat 25 is connected through the adjusting rod 271 and the spacing is finely adjusted. The clamping locking knob 283 is turned, and the clamping rod 281 moves down along the threaded hole, which drives the clamping member 282 to approach the pipe. Then, the clamping member 282 adapts to the curvature of the outer wall of the pipe through the rotating end 2811. Finally, the pipe is fixed in the support center with appropriate clamping force, and the centering is completed.
