Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, and in particular to a support device for water conservancy engineering. Background Technology

[0002] In the field of water conservancy engineering construction, pipeline support devices play a crucial role. The main functions of these devices are: ensuring the pipeline maintains a stable position within the water conservancy system, effectively preventing displacement, subsidence, or deformation; and significantly reducing vibrations caused by water flow impact, water pressure, and other external forces, thereby lowering the risk of fatigue-induced damage. Furthermore, these support devices facilitate pipeline installation, maintenance, and replacement, effectively reducing the difficulty of project implementation and lowering costs.

[0003] Patent CN222616206U discloses a pipe support device for water conservancy projects. This patent uses a bidirectional threaded rod to move two arc-shaped plates, thereby driving the first clamping structure and the second clamping structure to move in opposite directions. Under the action of the second clamping structure, the water pipe already clamped by the two first clamping structures can be further clamped and fixed. With the cooperation of the first clamping structure and the second clamping structure, it is convenient to clamp and fix water pipes of different radius sizes, which facilitates the widespread use of the device and improves its utilization rate.

[0004] However, this patent still reveals several shortcomings in practical applications. Specifically, firstly, the method of clamping the pipe by moving two arc-shaped plates only involves the arc-shaped plates being connected to the sliding block via a vertical rod. The upper part of the arc-shaped plates lacks any auxiliary connecting structure, resulting in a significant distance between the upper end and the bidirectional threaded rod. When clamping a large-diameter pipe, the force on the arc-shaped plates increases, making the upper end prone to deformation. Secondly, during pipe clamping, in the long-term operating environment of hydraulic engineering projects, the pipe is subjected to combined vibrations such as water flow impact and pressure fluctuations, which may cause "fretting wear" or "vibration loosening" of the threaded pair, leading to a gradual decrease in clamping force. Both of these shortcomings easily result in a decrease in the clamping force between the second buffer inclined plate and the pipe, reducing the clamping effect.

[0005] Therefore, how to improve the clamping effect of pipeline support devices in water conservancy projects has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0010] Multiple clamping mechanisms are arranged on the support frame. Each clamping mechanism includes a sliding frame and a driving component arranged in a one-to-one correspondence.

[0015] Furthermore, the driving assembly includes a driving rod that extends through the first sleeve, the driving rod being slidably sleeved on the outer side wall of the threaded rod near the first sleeve, and the two being able to rotate synchronously, the driving rod being detachably connected to the first sleeve.

[0016] Furthermore, the outer wall of the drive rod near the second sleeve is provided with a plurality of protrusions, and the plurality of protrusions are distributed in a circumferential array along the axial direction of the drive rod;

[0036] 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.

[0037] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figure 1 This utility model provides a support device for water conservancy projects. The device mainly consists of a base plate 1, two support frames 2 arranged vertically, and multiple clamping mechanisms arranged on the support frames 2.

[0039] Two support frames 2 are joined together at their midpoints and positioned around the periphery of the supporting pipe. These two support frames 2 can be assembled into a hollow structure. One end of each frame is hinged, while the other end is detachably connected, for example, using fasteners 3. The lower support frame 2 is fixedly mounted on the base plate 1. Clamping mechanisms are arranged on the support frames 2. In a preferred embodiment of this invention, each support frame 2 has three clamping mechanisms located on the same virtual circle, with adjacent clamping mechanisms forming a 45-degree angle. Specifically, each clamping mechanism includes a corresponding sliding frame 4 and a driving assembly 5. Multiple sliding frames 4 are slidably connected to the support frame 2 along the radial direction of the same virtual circle, with their adjacent ends used to clamp the pipe. The driving assembly 5 is detachably connected to the support frame 2 and is used to adjust the sliding displacement of the sliding frames 4.

[0040] Preferably, the support frame 2 includes, from the inside out, an inner ring frame 21, a middle ring frame 22 and several support rods 23. The support rods 23 are radially distributed and fixedly connected between the inner ring frame 21 and the middle ring frame 22 to form a stable support structure.

[0041] Specifically, the middle ring frame 22 has a first sleeve 24 fixedly inserted through it, and the inner ring frame 21 has a second sleeve 26 fixedly attached to it. A threaded rod 27 is rotatably connected inside the first sleeve 24 and the second sleeve 26. The threaded rod 27 is arranged along the radial direction of the virtual circle and is threadedly connected to the sliding frame 4. By driving the threaded rod 27 to rotate, the sliding frame 4 can be moved closer to or away from the center of the virtual circle.

[0042] Combined with reference Figure 2 The driving assembly 5 includes a driving rod 51 that movably passes through the first sleeve 24. The driving rod 51 is slidably sleeved on the outer wall of the threaded rod 27 near the first sleeve 24, and the two can rotate synchronously. The driving rod 51 is detachably connected to the first sleeve 24. Multiple protrusions 52 are provided on the outer wall of the driving rod 51 near the second sleeve 26, and these protrusions 52 are arranged in a circumferential array along the axial direction of the driving rod 51. Multiple notches 25 are provided on the edge of the first sleeve 24 near the second sleeve 26, and these notches 25 are detachably connected to the protrusions 52. When the protrusions 52 are embedded in the notches 25, the driving rod 51 cannot rotate circumferentially and cannot drive the threaded rod 27 to rotate, but it can still move axially. When the driving rod 51 moves along the axial direction, the protrusions 52 slide out of the notches 25, allowing the driving rod 51 to rotate axially and drive the threaded rod 27 to rotate synchronously. This achieves the effect of moving the sliding frame 4 closer to or away from the center of the virtual circle.

[0043] In addition, the drive assembly 5 also includes a limiting plate 53 and an elastic element 54 fixedly connected to the outer wall of the drive rod 51. The limiting plate 53 is located on the side of the middle ring frame 22 away from the second sleeve 26. The limiting plate 53 of this utility model has a ring structure. The two ends of the elastic element 54 are respectively connected to the limiting plate 53 and the middle ring frame 22. The elastic element 54 is used to drive the drive rod 51 to move away from the second sleeve 26. The elastic element 54 is preferably a compression spring.

[0044] Reference Figure 3-4 One end of the threaded rod 27, away from the second sleeve 26, is fixedly connected to a polygonal prism rod 28. The inner wall of the drive rod 51 is polygonal, and the drive rod 51 is slidably connected to the polygonal prism rod 28. A handwheel 55 is installed on the drive rod 51 located on the middle ring frame 22 away from the second sleeve 26. The polygonal prism rod 28 and the polygonal inner hole of the drive rod 51 form a circumferential positioning structure, ensuring that the drive rod 51 rotates synchronously with the threaded rod 27.

[0045] Refer again Figure 1 The sliding frame 4 includes a first support plate 41 threadedly connected to the threaded rod 27; a second support plate 42 located inside the inner ring frame 21 and parallel to the first support plate 41, with a buffer inclined plate 43 fixedly connected to the inner side of the second support plate 42. The buffer inclined plate 43 is preferably made of rubber, which is elastic and can effectively protect the outer wall of the water pipe and make the water pipe more secure when clamped. The buffer inclined plates 43 are arranged in pairs and have a symmetrical wedge structure with their tips facing each other to form a V-shaped clamping surface; and a plurality of guide rods 44 fixedly connected to the first support plate 41 and the second support plate 42 at both ends respectively. The guide rods 44 are parallel to the threaded rod 27 and slidably connected to the inner ring frame 21.

[0046] An outer ring frame 29 is fixedly connected to the outer side of the middle ring frame 22. The lower outer ring frame 29 is fixedly connected to the base plate 1. An operating space for the handwheel 55 is provided between the middle ring frame 22 and the outer ring frame 29.

[0047] In this utility model, the support frame 2 is usually provided in multiple sets, and the axes of the virtual circles of the multiple sets of support frames 2 coincide. The multiple sets of support frames 2 are connected by connecting rods 6.

[0048] The working principle of this utility model:

[0049] When using this support device, first, adjust the position of the sliding bracket 4 on the lower support frame 2 so that the length of the buffer inclined plate 43 on the inner side of the second support plate 42 and the center of the virtual circle are equal to the outer radius of the pipe to be supported. Then, disconnect the connection between the other ends of the upper and lower support frames 2, flip the upper support frame 2, and move the pipe onto the buffer inclined plate 43 of the lower support frame 2 by hoisting. Flip the two support frames 2 again to align their other ends and lock them with fasteners 3. Finally, adjust the position of the sliding bracket 4 on the upper support frame 2 so that the buffer inclined plate 43 on the inner side of the second support plate 42 fits against the outer wall of the pipe to be supported, thus achieving the desired pipe support effect.

[0050] It should be noted that the multiple sets of support frames 2 are connected by connecting rods 6, and their operation should be carried out synchronously.

[0051] The sliding displacement adjustment process for sliding bracket 4 is as follows:

[0052] During adjustment, hold the handwheel 55 and apply axial pressure. The drive rod 51 overcomes the spring force and moves towards the second sleeve 26 until the protrusion 52 disengages from the notch 25. Then, by rotating the handwheel 55, the drive rod 51 rotates. Due to the engagement between the drive rod 51 and the threaded rod 27, the threaded rod 27 rotates while simultaneously causing the sliding frame 4 to slide radially, moving it closer to or away from the center of the virtual circle. After adjustment, rotate the drive rod 51 at a small angle to align the protrusion 52 with the notch 25. Release the handwheel 55. The elastic element 54 provides power for the drive rod 51 to reset, causing the protrusion 52 to re-embed in the notch 25. At this point, the drive rod 51 cannot rotate axially, preventing the threaded rod 27 from rotating during use. This avoids a decrease in the clamping force on the pipe, ensuring the stability and reliability of the clamping mechanism.
