Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, and specifically relates to a pipeline support device for water conservancy and hydropower engineering. Background Technique

[0002] In water conservancy and hydropower engineering, pipelines usually need to transport a large amount of water flow and have a relatively high water pressure. The pipeline support device can provide stable support for the pipeline, preventing the pipeline from deforming, bending or even breaking due to its own weight, internal water flow pressure and external environmental factors such as wind force and earthquake, ensuring that the pipeline always maintains the correct position and shape during operation, and guaranteeing the safe and stable operation of the project;

[0003] The existing Chinese patent (publication number CN216408145U) proposes a pipeline support device for water conservancy and hydropower engineering. By setting the adjustment support device, it can deal with pipes of different diameters, so as to achieve the purpose of adjusting pipeline support. By setting the anti-slip pad made of rubber material on the inner wall of the second support plate, the friction force for clamping the pipeline can be increased, and at the same time, the pipe material can be protected;

[0004] Through the adjustment support device, the above patent can adjust the support device to adapt to pipes of different diameter sizes by using the cooperation of components such as a bidirectional threaded rod, a movable plate, a first support plate, a second support plate, a slide rod and a movable block, improving the practicability of the device;

[0005] However, in actual application, in some special water conservancy and hydropower projects, due to reasons such as design requirements, space limitations or cooperation with other equipment, square pipes will be used. For example, in some areas with narrow space, square pipes can make better use of space to achieve a compact layout. In the above patent support device, the top of the first support plate is fixedly connected to the top of the movable plate, the bottom of the second support plate is fixedly connected to the top of the movable block, and the top of the first support plate and the bottom of the second support plate are in contact. Through this structure, the support and clamping of the pipeline are realized. However, this design is based on the shape characteristics of circular pipes. The shapes of the support plate and the clamping structure are adapted to the circular pipe, and can better fit the surface of the circular pipe, so as to achieve uniform support and clamping. But for square pipes, the support plate and the clamping structure of this device are difficult to completely fit the surface of the special-shaped pipe, and it is impossible to achieve a uniform distribution of support and clamping force, which may lead to insufficient support in some areas or excessive clamping force, affecting the stability and safety of the pipeline. Content of the Utility Model

[0006] The purpose of the utility model is to provide a pipeline support device for water conservancy and hydropower engineering to solve the problems put forward in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A pipeline support device for water conservancy and hydropower projects, including an installation box, and a clamping assembly is arranged on the installation box;

[0008] The clamping assembly includes a V-shaped plate. A sliding groove is formed on the V-shaped plate. A sliding shaft is slidably connected in the sliding groove on the V-shaped plate. A sliding block is fixedly connected to the sliding shaft. A first rotating shaft is rotatably connected to the sliding block. A transmission block is rotatably connected to the first rotating shaft. An arc-shaped clamping member is fixedly connected to the transmission block. A support frame is slidably connected to the arc-shaped clamping member. An airbag is fixedly connected to the support frame. A first piston is slidably connected to the bottom of the airbag. The bottom of the first piston is fixedly connected to the transmission block. A second piston is slidably connected to the airbag. A pneumatic telescopic rod is fixedly connected to the second piston. Both ends of the pneumatic telescopic rod are fixedly connected with a spreading member. A clamping hoop is fixedly connected to the spreading member.

[0009] As a preferred implementation manner, a first electric telescopic rod is fixedly connected to the bottom of the V-shaped plate. The first electric telescopic rod is fixedly connected inside the installation box. The support frame is fixedly connected to the top of the installation box. Two ends of the clamping hoop are respectively fixedly connected with a first connecting piece and a second connecting piece. The second connecting piece is fixedly connected to the installation box. A first arc-shaped connecting piece is fixedly connected to the first connecting piece. A second rotating shaft is rotatably connected to the side of the first arc-shaped connecting piece away from the first connecting piece. A second electric telescopic rod is rotatably connected to the second rotating shaft. The second electric telescopic rod is fixedly connected to the installation box.

[0010] By adopting the above technical solution: By arranging the first electric telescopic rod, during use, the first telescopic rod drives the V-shaped plate to move up and down. The sliding block is driven to slide under the action of the sliding shaft, so that the transmission block is driven to move up and down, realizing the sliding of the arc-shaped clamping member in the support frame and realizing the fixation of the cylindrical pipeline.

[0011] As a preferred implementation manner, the first piston is fixedly connected to the end of the transmission block away from the first rotating shaft. There are three arc-shaped clamping members. The arc-shaped clamping member on the side close to the transmission block among the three arc-shaped clamping members is fixedly connected to the transmission block. Two second connecting pieces are fixedly connected to the transmission block. The two second connecting pieces are respectively fixedly connected to the two arc-shaped clamping members among the three arc-shaped clamping members away from the transmission block.

[0012] Adopt the above technical solution: When in use, when it is necessary to fix a square pipeline, at this time, since the arc-shaped clamping member is stuck at the corner of the square pipeline, the square pipe is used to play a limiting effect. When the transmission block continues to move, the transmission block rotates on the first rotating shaft, causing the first piston to be driven to tilt up, squeezing the airbag, so that the airbag pushes out the second piston and the pneumatic telescopic rod, driving the clamping hoop to slide out. The clamping hoop is composed of a wound elastic sheet, one end of which is fixedly connected to the installation box through the second connecting piece, and the other end is connected to the first arc-shaped connecting piece through the first connecting piece. The first arc-shaped connecting piece is also fixedly connected to the second electric telescopic rod. Then, start the second electric telescopic rod, so that the second electric telescopic rod drives the clamping hoop to tighten through the first arc-shaped connecting piece, and the fixation of the square pipeline can be realized. The pneumatic telescopic rod can keep the clamping hoop in a tight state all the time.

[0013] As a preferred embodiment, the clamping hoop is slidably connected to the support frame.

[0014] Adopt the above technical solution: By setting that the clamping hoop is slidably connected to the support frame, when not in use, the clamping hoop can be contracted and sleeved on the support frame to reduce the occupied space.

[0015] As a preferred embodiment, a fixed base is fixedly connected to the bottom of the installation box.

[0016] Adopt the above technical solution: By providing the fixed base and the threaded member, when in use, the fixed base can be fixed by screwing the threaded member into the ground to realize the fixation of the installation box.

[0017] As a preferred embodiment, a threaded member is threadedly connected to the fixed base.

[0018] Adopt the above technical solution: By providing the threaded member, it is convenient to fix the device during use.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0020] In the present utility model, the clamping assembly can not only effectively fix the cylindrical pipeline through a specific structure, but also, when facing a square pipeline, utilize the limiting effect of the arc-shaped clamping member stuck at the corner of the square pipeline, and through a series of transmissions, tighten the clamping hoop to realize the stable fixation of the square pipeline. The clamping hoop is always in a tight state under the action of the pneumatic telescopic rod, ensuring the firm fixation of the square pipeline, greatly improving the applicability of the pipeline support device in water conservancy and hydropower projects, meeting the pipeline installation requirements under different design requirements and space limitations, ensuring the stability and safety of the pipeline, and solving the problem that the prior art in the background art cannot fix the square pipeline.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1-4 shown, a pipeline support device for water conservancy and hydropower projects includes an installation box 1, and a clamping assembly 2 is arranged on the installation box 1;

[0032] The clamping assembly 2 includes a V-shaped plate 214. A sliding groove is formed in the V-shaped plate 214. A sliding shaft 28 is slidably connected in the sliding groove of the V-shaped plate 214. A sliding block 22 is fixedly connected to the sliding shaft 28. A first rotating shaft 23 is rotatably connected to the sliding block 22. A transmission block 21 is rotatably connected to the first rotating shaft 23. An arc-shaped clamping member 24 is fixedly connected to the transmission block 21. A support frame 25 is slidably connected to the arc-shaped clamping member 24. An airbag 210 is fixedly connected to the support frame 25. A first piston 29 is slidably connected to the bottom of the airbag 210. The bottom of the first piston 29 is fixedly connected to the transmission block 21. A second piston 211 is slidably connected to the airbag 210. A pneumatic telescopic rod 212 is fixedly connected to the second piston 211. Both ends of the pneumatic telescopic rod 212 are fixedly connected with a spreading member 213. A clamping hoop 27 is fixedly connected to the spreading member 213;

[0033] The clamping assembly 2 can not only effectively fix the cylindrical pipeline through a specific structure, but also when facing a square pipeline, utilize the limiting effect of the arc-shaped clamping member 24 stuck at the corner of the square pipeline. Through a series of transmissions, the clamping hoop 27 is tightened to achieve stable fixation of the square pipeline. The clamping hoop 27 is always in a tense state under the action of the pneumatic telescopic rod 212, ensuring firm fixation of the square pipeline, greatly improving the applicability of the pipeline support device in water conservancy and hydropower projects, meeting the pipeline installation requirements under different design requirements and space limitations, ensuring the stability and safety of the pipeline, and solving the problem that the prior art in the background technology cannot fix the square pipeline.

[0034] Furthermore, as Figures 1 to 4 shown, a first electric telescopic rod 26 is fixedly connected to the bottom of the V-shaped plate 214. The first electric telescopic rod 26 is fixedly connected in the installation box 1. The support frame 25 is fixedly connected to the top of the installation box 1. Two ends of the clamping hoop 27 are respectively fixedly connected with a first connecting piece 215 and a second connecting piece 219. The second connecting piece 219 is fixedly connected to the installation box 1. A first arc-shaped connecting piece 216 is fixedly connected to the first connecting piece 215. A second rotating shaft 217 is rotatably connected to the side of the first arc-shaped connecting piece 216 away from the first connecting piece 215. A second electric telescopic rod 218 is rotatably connected to the second rotating shaft 217. The second electric telescopic rod 218 is fixedly connected to the installation box 1. By setting the first electric telescopic rod 26, during use, the first telescopic rod drives the V-shaped plate 214 to move up and down, and the sliding block 22 is driven to slide under the action of the sliding shaft 28, so that the transmission block 21 is driven to move up and down, realizing the sliding of the arc-shaped clamping member 24 in the support frame 25 and achieving the fixation of the cylindrical pipeline;

[0035] The first piston 29 is fixedly connected to one end of the transmission block 21 away from the first rotating shaft 23. There are three arc-shaped clamping members 24. The arc-shaped clamping member 24 on the side close to the transmission block 21 among the three arc-shaped clamping members 24 is fixedly connected to the transmission block 21. There are two second connecting members 3 fixedly connected to the transmission block 21. The two second connecting members 3 are respectively fixedly connected to the two arc-shaped clamping members 24 away from the transmission block 21 among the three arc-shaped clamping members 24. When in use, when a square pipeline needs to be fixed, at this time, since the arc-shaped clamping member 24 is stuck at the corner of the square pipeline, the square pipe is used to play a limiting role. When the transmission block 21 continues to move, the transmission block 21 rotates on the first rotating shaft 23, causing the first piston 29 to be driven to tilt up, squeezing the airbag 210, so that the airbag 210 pushes out the second piston 211 and the pneumatic telescopic rod 212, driving the clamping hoop 27 to slide out. The clamping hoop 27 is composed of a wound elastic sheet. One end is fixedly connected to the installation box 1 through the second connecting piece 219, and the other end is connected to the first arc-shaped connecting piece 216 through the first connecting piece 215. The first arc-shaped connecting piece 216 is also fixedly connected to the second electric telescopic rod 218. After that, the second electric telescopic rod 218 is started, so that the second electric telescopic rod 218 drives the clamping hoop 27 to tighten through the first arc-shaped connecting piece 216, and the fixation of the square pipeline can be realized. The pneumatic telescopic rod 212 can keep the clamping hoop 27 in a tight state at all times;

[0036] The clamping hoop 27 is slidably connected to the support frame 25. By setting the clamping hoop 27 to be slidably connected to the support frame 25, when not in use, the clamping hoop 27 can be contracted and sleeved on the support frame 25 to reduce the occupied space.

[0037] In the above solution, there is also a problem that how to install the installation box 1 is not proposed, such as Figure 1 、 Figure 2 、 Figure 4 As shown, a fixed base 4 is fixedly connected to the bottom of the installation box 1. By providing the fixed base 4 and the threaded member 41, when in use, the fixed base 4 can be fixed by screwing the threaded member 41 into the ground, realizing the fixation of the installation box 1;

[0038] The threaded member 41 is threadedly connected to the fixed base 4. By providing the threaded member 41, it is convenient to fix the device during use.

[0039] Working principle: As shown in Figure 1 - Figure 4As shown, for fixing the cylindrical pipe, the first electric telescopic rod 26 arranged in the installation box 1 is started to drive the V-shaped plate to move up and down, and a sliding shaft 28 is slidably connected in the sliding groove on the V-shaped plate. When the V-shaped plate moves, the sliding block 22 on the sliding shaft 28 is driven to slide under the action of the sliding shaft 28, and the first rotating shaft 23 rotatably connected to the sliding block 22 is connected to the transmission block 21, so that the transmission block 21 is driven to move up and down, thereby realizing the sliding of the arc-shaped clamping member 24 in the support frame 25, thereby realizing the fixing of the cylindrical pipe;

[0040] When the square pipe needs to be fixed, the arc-shaped clamping member 24 is stuck at the corner of the square pipe, and the square pipe has a limiting effect. When the transmission block 21 continues to move, the transmission block 21 rotates on the first rotating shaft 23, so that the first piston 29 fixedly connected to the transmission block 21 at one end away from the first rotating shaft 23 is driven to tilt up, squeezing the airbag 210. After the airbag 210 is squeezed, the second piston 211 and the pneumatic telescopic rod 212 are pushed out, driving the clamping hoop 27 to slide out. The clamping hoop 27 is composed of a wound elastic sheet, one end of which is fixedly connected to the installation box 1 through the second connecting piece 219, and the other end is connected to the first arc-shaped connecting member 216 through the first connecting piece 215. The first arc-shaped connecting member 216 is fixedly connected to the second electric telescopic rod 218. After that, the second electric telescopic rod 218 is started, and the second electric telescopic rod 218 is driven to move. The square pipe can be fixed by tightening the clamping hoop 27 through the first arc-shaped connecting member 216, and the pneumatic telescopic rod 212 drives the expansion member 213 to tighten, so that the clamping hoop 27 is always in a tight state. When not in use, the clamping hoop 27 is sleeved on the support frame 25, so it can slide smoothly to the outer wall of the square pipe. At the same time, the clamping hoop 27 is slidably connected to the support frame 25. When it is not needed, the clamping hoop 27 can be partially retracted and sleeved on the support frame 25 to reduce the occupied space. In addition, the bottom of the installation box 1 is fixedly connected to a fixed base 4, and a threaded member 41 is threadedly connected to the fixed base 4. Before use, the fixed base 4 can be fixed by screwing the threaded member 41 into the ground, thereby fixing the installation box 1.
