Description

Technical Field

[0001] This utility model belongs to the field of pipeline maintenance support, specifically a temporary support device for pipeline maintenance. Background Technology

[0002] As the core carrier of fluid transportation, water supply pipelines play a crucial role in ensuring the stable delivery of water resources. Operating in complex environments for extended periods, they are highly susceptible to malfunctions such as pipe wall damage and localized deformation, thus requiring regular inspection and maintenance. During pipeline maintenance, to prevent displacement, tilting, or even collapse due to the pipeline's own weight or maintenance operations, temporary support devices are needed to securely support the pipeline.

[0003] For example, Chinese patent with publication number "CN221583526U" discloses "a pipe maintenance support frame, including a base plate, wherein a movable plate is provided at the center of the top wall of the base plate, and the movable plate is connected to the base plate through a first lifting component... This utility model provides a pipe maintenance support frame to solve the problem that in the prior art, the height of the existing pipe support frame cannot be adjusted during use, resulting in a low range of application and certain limitations, and it cannot well meet the actual use needs."

[0004] However, in water supply pipeline systems, pipe types are not singular. Besides conventional circular metal water supply pipes, square water supply pipes are increasingly used to adapt to narrow installation spaces (such as building interior ceilings and underground pipe gallery mezzanines) or to reduce water flow resistance. The aforementioned patent achieves stable support by having an arc-shaped placement groove fit snugly against the outer side of the circular pipe. However, when facing the maintenance needs of square pipes, due to the right-angled sides and flat surface of the square pipe, its outer wall cannot effectively fit against the arc-shaped placement groove. Support is only possible by the corners of the square pipe contacting the arc-shaped groove, which easily leads to slippage and displacement of the pipe during support. Therefore, different types of support plates need to be replaced to suit the square pipe, increasing costs, extending maintenance time, and reducing practicality.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a temporary support device for pipeline maintenance. Utility Model Content

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a temporary support device for pipeline maintenance, including a base plate 1, an electric actuator 2 on the upper part of the base plate 1, a movable plate 3 on the upper part of the electric actuator 2, two symmetrically distributed support components 4 on the upper part of the movable plate 3 for supporting the pipeline, and symmetrically distributed adjustment components 5 on the bottom of the movable plate 3 for adjusting the position of the support components 4.

[0021] refer to Figure 1 and Figure 2 The support assembly 4 includes two mounting plates 41 symmetrically distributed on the upper part of the movable plate 3. A connecting rod 42 is provided between the two mounting plates 41. A support plate 43 is rotatably mounted on the connecting rod 42. An arc-shaped groove 44 is provided on the upper part of the support plate 43, and a rectangular groove 45 is provided on the bottom of the support plate 43.

[0022] refer to Figure 1 and Figure 4 The upper part of the base plate 1 is provided with two symmetrically distributed telescopic rods 10, and the top of the telescopic rods 10 is connected to the bottom of the movable plate 3. The bottom of the base plate 1 is provided with casters 11 on all four sides.

[0023] When supporting the circular pipe, the electric actuator 2 moves the moving plate 3 upward, and the moving plate 3 moves upward, which in turn moves the support plate 43 upward through the telescopic rod 10. When the arc groove 44 on the support plate 43 fits against the outer side of the circular pipe, the electric actuator 2 stops working. At this time, the circular pipe can be stably supported by the cooperation of the support plate 43 and the arc groove 44.

[0024] refer to Figure 2 The adjustment component 5 includes a limiting rod 51 that slides through the movable plate 3. A pull ring 52 is provided at the bottom of the limiting rod 51. A spring 53 is sleeved on the outside of the limiting rod 51. The two ends of the spring 53 are respectively connected to the pull ring 52 and the bottom of the movable plate 3.

[0025] refer to Figure 2 , Figure 3 and Figure 4 Limiting holes 6 are provided at the arc-shaped groove 44 and the rectangular groove 45 on the support plate 43, and the two limiting holes 6 are connected to the arc-shaped groove 44 and the rectangular groove 45 respectively. The top end of the limiting rod 51 is inserted into the corresponding limiting hole 6.

[0026] When supporting the square pipe, the worker can first pull the pull ring 52, causing the limiting rod 51 to slide downwards. During this process, the limiting rod 51 will simultaneously stretch the spring 53, and its top end will completely move out of the limiting hole 6. At this time, the support plate 43 loses its limiting lock and can rotate freely around the connecting rod 42. Then, the support plate 43 is rotated 180 degrees along the connecting rod 42, causing the rectangular groove 45, which was originally facing downwards, to flip to the upwards position, and the arc groove 44 to flip to the downwards position simultaneously, completing the switching of the support surface. After the switching is completed, the pull ring 52 is released, and the elastic force of the spring 53 can drive the limiting rod 51 to reset and re-insert into the corresponding limiting hole 6, realizing the re-limiting and locking of the support plate 43, and preventing the support plate 43 from rotating and shifting during the support process. At this time, the electric push rod 2 is activated to drive the moving plate 3 to move upwards until the upward-facing rectangular groove 45 is completely in contact with the bottom plane of the square pipe, thereby achieving stable support for the square pipe without the need to replace the new support plate 43, thus improving the support efficiency.

[0027] refer to Figure 1 and Figure 3 The bottom of the support plate 43 has two sliding openings 7 that are connected to the rectangular groove 45 and are symmetrically distributed. The sliding openings 7 are equipped with limiting components 8 for limiting the pipe.

[0028] refer to Figure 2 and Figure 3 The limiting component 8 includes a slider 81 that is slidably disposed in the sliding opening 7. A limiting block 82 is provided at the bottom of the slider 81. The side of the two limiting blocks 82 that are close to each other is sloping. A fastening bolt 83 is threaded on the front side of the slider 81.

[0029] refer to Figure 3 Two rectangular openings 9 are symmetrically distributed on the opposite sides of the two support plates 43, and the rectangular openings 9 are connected to the sliding openings 7. One end of the fastening bolt 83 passes through the rectangular opening 9, and one side of the protruding edge of the fastening bolt 83 abuts against the outer side of the support plate 43.

[0030] When supporting the square pipe, after the rectangular groove 45 is in contact with the bottom of the square pipe, the fastening bolt 83 can be loosened to separate its protruding edge from the outside of the support plate 43, thereby releasing the fixation restriction on the slider 81. At this time, the slider 81 can slide freely along the sliding opening 7. The operator can push the two limiting blocks 82 to move along the sliding opening 7 towards the square pipe until the sides of the two limiting blocks 82 are completely pressed against both sides of the square pipe, forming a lateral clamping limit on the pipe. After the position of the limiting blocks 82 is adjusted to the correct position, the fastening bolt 83 is tightened again in the opposite direction so that its protruding edge is tightly pressed against the outside of the support plate 43, thereby locking the limiting blocks 82. At this time, the square pipe is not only supported by the rectangular groove 45, but also clamped by the sloping surfaces of the limiting blocks 82 on both sides, effectively limiting the sliding and displacement of the pipe in the horizontal direction. Even if there is a slight external force collision during maintenance, it can ensure that the square pipe is always in a stable support state, further improving the reliability and safety of the support device.

[0031] Working principle: When providing temporary support for a pipeline, the support plate 43 can be moved to the bottom of the pipeline using the casters 11. Then, the appropriate support method is selected based on the pipeline shape. For a circular pipeline, the electric actuator 2 is activated to move the upper movable plate 3 upwards, which in turn moves the support plate 43 upwards. When the arc-shaped groove 44 on the upper part of the support plate 43 is fully in contact with the outer side of the circular pipeline, the electric actuator 2 stops working. At this point, the support plate 43 and the arc-shaped groove 44 work together to stably support the circular pipeline. For a square pipeline, the operator first pulls the pull ring 52 to move the limiting rod 51 downwards. During the downward movement of the limiting rod 51, the spring 53 on the outer side is stretched and moves out of the limiting hole 6 at the arc-shaped groove 44 of the support plate 43, releasing the limiting lock on the support plate 43. Then, the support plate 43 is rotated 180 degrees around the connecting rod 42 between the two mounting plates 41, causing the rectangular groove 45 at the bottom of the support plate 43 to flip. Turn the tube upwards with the arc groove 44 downwards, and after releasing the pull ring 52, the elastic force of the spring 53 drives the limit rod 51 to reset and re-insert into the limit hole 6 at the rectangular groove 45 of the support plate 43, completing the re-limiting and locking of the support plate 43. Then, start the electric push rod 2 to move the moving plate 3 upwards until the rectangular groove 45 is completely in contact with the bottom plane of the square pipe. After that, loosen the fastening bolt 83 to release the fixation of the slider 81 in the sliding port 7, and then push the slider 81 to move the limit block 82 until the two limit blocks 82 are close to each other and completely abut against both sides of the square pipe. Then tighten the fastening bolt 83 in the opposite direction, and fix the position of the slider 81 and the limit block 82 by the tight contact between its convex edge and the outside of the support plate 43. At this time, the square pipe is supported by the rectangular groove 45 and clamped by the limit blocks 82 on both sides, effectively limiting the horizontal sliding and displacement, and finally achieving stable temporary support for pipes of different shapes to meet maintenance needs.
