Description

Technical Field

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

[0002] In municipal water supply and drainage engineering, the pipeline system serves as the "lifeline" of urban infrastructure, and its safety, stability, and long-term operation are of paramount importance. Pipeline fixing and support devices, widely used in modern urban integrated pipe corridors, are core components ensuring the normal function of the pipeline system. They primarily bear the weight of the pipeline itself, internal fluid loads, thermal stress caused by temperature changes, and dynamic loads such as earthquakes, effectively suppressing excessive pipeline displacement, vibration, and deformation, thereby avoiding serious consequences such as loose joints and pipe rupture.

[0003] Currently, most common pipe fixing and support devices on the market adopt traditional full-enclosed clamp structures, which form a rigid constraint by circumferentially clamping the pipe. Although this type of structure can provide high initial constraint strength, when the pipe expands and contracts due to temperature changes, the rigid contact between the clamp and the pipe wall severely restricts deformation, causing the reaction force to concentrate in a narrow area at the edge of the clamp. This edge stress concentration phenomenon can easily cause local plastic deformation of the pipe wall, coating damage, or even pipe crushing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a pipe fixing support device to solve the problem in the prior art that when the pipe expands and contracts due to temperature changes, the force will be concentrated in the narrow contact area of ​​the clamp edge, and the pipe wall is easily damaged due to the reverse force of the fully enclosed clamp.

[0005] This utility model is achieved through the following technical solution: A pipe fixing support device includes a support frame and two first arc-shaped plates fixedly installed on the support frame. A second arc-shaped plate is disposed between the two first arc-shaped plates. The second arc-shaped plate is rotatably connected to the two first arc-shaped plates. A locking assembly is installed between the second arc-shaped plate and the two first arc-shaped plates. When the second arc-shaped plate and the two first arc-shaped plates are locked together, they form a ring and are arranged alternately. A channel for the pipe to pass through is left between the second arc-shaped plate and the two first arc-shaped plates.

[0006] Furthermore, both sides of the second arc-shaped plate are fixedly connected to a rotating shaft, and both first arc-shaped plates are provided with grooves that are adapted to the corresponding rotating shafts.

[0007] Furthermore, both grooves extend along the arc length direction of the corresponding first arc plate.

[0008] Furthermore, the locking assembly includes a first plate body fixedly connected to the two first arc-shaped plates and a second plate body fixedly connected to the side of the second arc-shaped plate away from the pivot. Both the first plate body and the second plate body are provided with through holes. When the first plate body and the second plate body are in contact, the central axes of the two through holes coincide, and bolts are inserted into the two through holes.

[0009] Furthermore, a limiting plate is fixedly connected to the side of the two first arc-shaped plates away from the first plate body.

[0010] Furthermore, the support frame includes a vertically arranged support plate and a horizontally arranged base plate. The base plate is fixedly connected to the bottom surface of the support plate, and multiple reinforcing ribs are provided at the connection between the base plate and the support plate.

[0011] Furthermore, a handle is fixedly connected to the second arc-shaped plate. The handle is located on the side of the second arc-shaped plate near the pivot. A notch is provided on the support plate for the handle to pass through.

[0012] Furthermore, elastic gaskets are fixedly installed on one side wall of the pipe where the second arc-shaped plate and the two first arc-shaped plates are attached.

[0013] The beneficial effects of this utility model are as follows: This pipe fixing support device, by arranging the second arc-shaped plate alternately with the two first arc-shaped plates, allows each section of the pipe to contact the outside air, improving heat dissipation efficiency. When the pipe expands and contracts with heat, it can deform towards the side that is not in contact with the first or second arc-shaped plate, alleviating the huge thermal stress caused by complete constraint and reducing the risk of local damage to the pipe wall.

[0022] Please see Figure 1-5This utility model provides a technical solution: a pipe fixing support device, including a support frame 1 and two first arc-shaped plates 2 fixedly installed on the support frame 1. A second arc-shaped plate 3 is provided between the two first arc-shaped plates 2. The second arc-shaped plate 3 is rotatably connected to the two first arc-shaped plates 2. A locking component 4 is installed between the second arc-shaped plate 3 and the two first arc-shaped plates 2. When the second arc-shaped plate 3 and the two first arc-shaped plates 2 are locked together, they form a ring and are arranged alternately. A channel for a pipe 18 to pass through is left between the second arc-shaped plate 3 and the two first arc-shaped plates 2.

[0023] The second arc plate 3 has a rotating shaft 5 fixedly connected to both sides. The two first arc plates 2 are provided with grooves 6 that are adapted to the corresponding rotating shafts 5. The two grooves 6 extend along the arc length direction of the corresponding first arc plate 2.

[0024] The locking assembly 4 includes a first plate 7 fixedly connected to the two first arc-shaped plates 2 and a second plate 8 fixedly connected to the side of the second arc-shaped plate 3 away from the rotating shaft 5. Both the first plate 7 and the second plate 8 are provided with through holes 9. When the first plate 7 and the second plate 8 are in contact, the central axes of the two through holes 9 coincide, and bolts 10 are inserted into the two through holes 9.

[0025] A limiting plate 11 is fixedly connected to the side of the two first arc-shaped plates 2 away from the first plate body 7.

[0026] In this scheme: both the first arc plate 2 and the second arc plate 3 are arc-shaped. Through the two first arc plates 2 fixed on the support frame 1 and the rotatable second arc plate 3, the pipe 18 can be arranged in an alternating manner to accommodate and hold the pipe 18.

[0027] The second arc-shaped plate 3 is rotatably connected to the two first arc-shaped plates 2 by means of the rotating shafts 5 on both sides, which cooperate with the grooves 6 on the two first arc-shaped plates 2, so that the pipe 18 can be placed on the two first arc-shaped plates 2. The grooves 6 are arc-shaped and extend along the length direction of the first arc-shaped plate 2. The rotating shafts 5 can slide along the length direction of the grooves 6, and the second arc-shaped plate 3 can rotate to be on the same arc surface as the first arc-shaped plate 2, which reduces the space occupied and facilitates transportation.

[0028] By fixing the first plate 7 to the two first arc-shaped plates 2, and fixing the second plate 8 to the side of the second arc-shaped plate 3 away from the rotating shaft 5, and by opening through holes 9 on both the first plate 7 and the second plate 8, when the first plate 7 and the second plate 8 are in contact, the central axes of the two through holes 9 coincide. At this time, by passing the bolt 10 through the two through holes 9, the first arc-shaped plate 2 and the second arc-shaped plate 3 can be fixed, thereby fixing the pipe 18.

[0029] A limiting plate 11 is fixedly connected to the side of the two first arc-shaped plates 2 away from the first plate body 7. This provides auxiliary support for the second arc-shaped plate 3. During the movement of the two rotating shafts 5 along the length direction of the corresponding grooves 6, the second arc-shaped plate 3 rotates around the central axis of the pipe 18.

[0030] How to use: Step 1: Install the support frame 1 in the predetermined position.

[0031] Step 2: Loosen bolt 10 and push the second arc plate 3 to slide along the length of the groove 6 until the second arc plate 3 and the first arc plate 2 are on the same arc surface.

[0032] Step 3: Place the pipe 18 on the supporting surface of the first arc plate 2 and the second arc plate 3.

[0033] Step 4: Rotate the second arc plate 3 upwards until it closes with the first arc plate 2, so that the first plate 7 and the second plate 8 are in contact. Pass the bolt 10 through the two through holes 9 and tighten the nut. The tension of the bolt 10 will fix the pipe 18 between the first arc plate 2 and the second arc plate 3.

[0034] Technical effects: Compared to the fully enclosed clamps in the existing technology, the second arc plate 3 is arranged alternately with the two first arc plates 2, so that each section of the pipe 18 can contact the outside air, which improves the heat dissipation efficiency. When the pipe 18 expands and contracts with heat, it can deform to the side that is not in contact with the first arc plate 2 or the second arc plate 3, which alleviates the huge thermal stress caused by complete constraint and reduces the risk of local damage to the pipe wall.

[0035] In this embodiment: the support frame 1 includes a vertically arranged support plate 12 and a horizontally arranged base plate 13. The base plate 13 is fixedly connected to the bottom surface of the support plate 12, and a plurality of reinforcing ribs 14 are provided at the connection between the base plate 13 and the support plate 12.

[0036] In this scheme: the support plate 12 provides vertical support height, raising the two first arc-shaped plates 2 to the required position.

[0037] The base plate 13 is stably connected to the ground or ground piles by means of bolts 10, etc. due to its large surface area.

[0038] The reinforcing rib 14 enhances the connection strength between the support plate 12 and the base plate 13 by utilizing the principle of triangular stability.

[0039] In this embodiment: a handle 15 is fixedly connected to the second arc plate 3. The handle 15 is located on the side of the second arc plate 3 near the rotating shaft 5. A notch 16 is provided on the support plate 12 for the handle 15 to pass through.

[0040] In this design, handle 15 provides the operator with a convenient point of leverage. When it is necessary to move the second arc-shaped plate 3, the operator uses handle 15 to push or pull the arc-shaped plate.

[0041] The notch 16 on the support plate 12 provides space for the movement trajectory of the handle 15 during rotation, ensuring that the second arc plate 3 can be opened smoothly to the maximum angle without being blocked by the support plate 12.

[0042] In this embodiment, elastic pads 17 are fixedly installed on one side wall of the second arc plate 3 and the two first arc plates 2 that are attached to the pipe 18.

[0043] In this design, the elastic gasket 17 can be made of elastic materials such as rubber or polyurethane, and is filled between the inner wall (the side wall that fits against the pipe 18) of the first arc-shaped plate 2 and the second arc-shaped plate 3 and the outer wall of the pipe 18. The elastic gasket 17 will undergo elastic deformation under pressure. This increases the friction between the first arc-shaped plate 2 and the second arc-shaped plate 3 and the surface of the pipe 18, reducing the amount of slippage of the pipe 18. It also reduces the direct contact between the first arc-shaped plate 2 and the second arc-shaped plate 3, preventing scratches or abrasions to the anti-corrosion coating or the pipe body itself of the pipe 18.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
