Description

Technical Field

[0001] This utility model belongs to the field of pipe supports, and in particular relates to a water conservancy pipeline support frame. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the goals of harm prevention and water conservation. The construction of water conservancy projects requires water pipelines, which are fundamental water conservancy infrastructure. For example, water pipelines allow water from canals to flow into farmland for irrigation. During the laying of water pipelines, pipe supports are needed to secure them, bear their own weight, and keep the stress within permissible limits, thus extending the service life of the water conservancy pipelines.

[0003] The existing hydraulic pipeline support frame consists of two symmetrical arc-shaped support plates, a base, and fastening bolts. The pipeline is sandwiched between the two arc-shaped support plates. However, because the curvature of the arc-shaped support plates is different from that of the pipeline, the actual contact area between the pipeline and the arc-shaped support plates is very limited. This results in poor stability of the hydraulic pipeline on the support. In addition, the arc-shaped support plates are rigid supports, which makes the pipeline prone to wear or significant noise due to water flow impact or equipment operation vibration. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic pipeline support frame that can reduce vibration and improve the stability of the pipeline.

[0005] The aforementioned water conservancy pipeline support frame includes a support column, a base fixed to the bottom of the support column, and two symmetrically distributed, elliptical arc-shaped plates fixed to the top of the support column. A support plate is provided above each arc-shaped plate, and the two support plates are distributed vertically and are both extensible. The middle of each support plate is connected to the inner wall of the corresponding arc-shaped plate through a spring shock absorber. Spring telescopic rods are hinged to the left and right ends of each support plate, and the movable ends of the spring telescopic rods are hinged to the arc-shaped plate corresponding to the support plate.

[0006] Furthermore, the base includes a mounting block fixed to the bottom of the support column, and two fixing plates are fixed to the left and right sides of the mounting block for fixing the mounting block to the ground.

[0007] Furthermore, connecting plates are fixed to both ends of the two arc-shaped plates. The bottom of the lower arc-shaped plate is fixed to the top of the support column, and the upper arc-shaped plate is connected to the lower arc-shaped plate by fastening bolts.

[0008] Furthermore, the spring damper includes a first spring, with connecting blocks fixed at both ends of the first spring. One connecting block is fixed to a support plate, and the other connecting block is fixed to an arc-shaped plate corresponding to the support plate. A damper is installed on the inner side of the first spring.

[0009] Furthermore, the spring telescopic rod includes a fixed rod, one end of which is fitted with a sleeve rod that slides up and down with it. A second spring is provided inside the sleeve rod. The elastic coefficient of the second spring is greater than that of the first spring. One end of the second spring is fixed to the inner bottom of the sleeve rod, and the other end is fixed to the end of the fixed rod located inside the sleeve rod. When the second spring is in its natural state, the end of the fixed rod connected to the second spring is located inside the sleeve rod.

[0010] Furthermore, one end of the fixing rod located inside the sleeve is fixed with a limiting block to prevent the fixing rod from sliding out of the sleeve, and the other end of the second spring is fixed on the limiting block.

[0011] Furthermore, a rubber pad is fixed to the contact surface between the support plate and the water pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention uses a spring damper to install a support plate on the inner side of a corresponding arc-shaped plate, allowing the water pipe to be clamped between the two support plates. When the water pipe vibrates due to the continuous impact of the water flow, the spring damper absorbs the energy generated by the vibration and suppresses the repeated jumping of the water pipe, thereby reducing or eliminating these periodic vibrations or instantaneous impacts caused by factors such as water flow and wind. This reduces pipe wear and noise. Furthermore, after clamping the water pipe between the two support plates, the pipe's own weight and the clamping force generated by tightening the bolts bring the middle of the two support plates closer to the corresponding arc-shaped plate. The left and right ends of the extendable support plate, supported by the spring telescopic rods hinged to them, gradually adhere to the outer wall of the water pipe, increasing the contact area between the support plate and the water pipe, making the pipe more stable, and further reducing pipe vibration.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0020] The water conservancy pipeline support frame described in this embodiment includes a support column 3, and a base is fixed to the bottom of the support column 3, such as... Figure 1 and Figure 4 As shown, the base includes an installation block 2 fixed to the bottom of the support column 3. Two fixing plates 1 for fixing the installation block 2 to the ground are fixed on the left and right sides of the installation block 2. The fixing plates 1 are fixed to the ground by means of anchor rods, bolts, etc.

[0021] Two symmetrically distributed, elliptical-shaped arc plates 4 are fixed to the top of the support column 3. Figure 1 and Figure 4 As shown, connecting plates 5 are fixed to both ends of the two arc-shaped plates 4. The bottom of the lower arc-shaped plate 4 is fixed to the top of the support column 3, and the upper arc-shaped plate 4 is connected to the lower arc-shaped plate 4 by fastening bolts. The water pipe is sandwiched between the two arc-shaped plates 4. The two connecting plates 5 on the left and the two connecting plates 5 on the right are each connected by fastening bolts. The tighter the fastening bolts are rotated, the tighter the two arc-shaped plates 4 are sandwiched.

[0022] Above each of the supporting columns 3, a supporting plate 7 is provided corresponding to each arc-shaped plate 4. The two supporting plates 7 are distributed vertically and are both extensible. Figure 1 As shown, the upper support plate 7 corresponds to the upper arc plate 4, and the lower support plate 7 corresponds to the lower arc plate 4. The support plate 7 has a certain rigidity but can be bent manually. Specifically, it can be made of engineering plastics such as polypropylene and polyvinyl chloride or elastic materials such as polyurethane and silicone rubber.

[0023] Each support plate 7 is connected to the inner wall of the corresponding arc-shaped plate 4 via a spring damper at its center. In this embodiment, the support plate 7 is installed on the inner side of the corresponding arc-shaped plate 4 using the spring damper, which allows the water pipe to be clamped between the two support plates 7. When the water pipe vibrates due to the continuous impact of the water flow inside the pipe, the spring damper absorbs the energy generated by the vibration and suppresses the repeated jumping of the water pipe, thereby reducing or eliminating these periodic vibrations or instantaneous impacts of the pipe caused by factors such as water flow and wind, thus reducing pipe wear and noise; Figure 1 , Figure 2 and Figure 4 As shown, the spring damper in this embodiment includes a first spring 10, with connecting blocks 11 fixed at both ends of the first spring 10. One connecting block 11 is fixed to the support plate 7, and the other connecting block 11 is fixed to the arc-shaped plate 4 corresponding to the support plate 7. A damper 9 is installed inside the first spring 10. The damper 9 can be a hydraulic structure or an elastomeric damping material structure. This embodiment uses a hydraulic structure, which mainly consists of a piston, piston rod, cylinder, oil, throttle orifice, and check valve. One end of the cylinder is fixed to the connecting block 11 fixed to the arc-shaped plate 4, and one end of the piston rod is fixed to the connecting block 11 fixed to the arc-shaped plate 4. Fixed on the connecting block 11 that is fixed to the support plate 7, when the first spring 10 is compressed to absorb the vibration of the pipeline, the piston in the damper 9 moves downward relative to the cylinder. At this time, the oil flows through the throttle orifice and the one-way valve at the same time. The flow area is large and the damping force generated is small, so that the first spring 10 can fully compress to absorb the vibration of the pipeline. When the first spring 10 is stretched to release the vibration energy, the piston in the damper 9 moves upward relative to the cylinder. At this time, the one-way valve on the piston is closed, and the oil can only flow through the throttle orifice. The flow area is small and a large damping force is generated, thereby quickly attenuating the vibration of the first spring 10.

[0024] Each support plate 7 has a spring telescopic rod 8 hinged to both its left and right ends. The movable ends of the spring telescopic rods 8 are hinged to the arc-shaped plates 4 corresponding to the support plate 7. In this embodiment, after the water pipe is sandwiched between two support plates 7, the weight of the pipe and the clamping force generated by tightening the fastening bolts 6 allow the middle parts of the two support plates 7 to move closer to the corresponding arc-shaped plates 4. The left and right ends of the extensible support plates 7, supported by the spring telescopic rods 8, can gradually adhere to the outer wall of the water pipe, thereby increasing the contact area between the support plates 7 and the water pipe, making the pipe more stable, and further reducing pipe vibration. Figure 3As shown, the spring telescopic rod 8 includes a fixed rod 8.1. One end of the fixed rod 8.1 is fitted with a sleeve rod 8.4 that slides vertically with it. A second spring 8.3 is provided inside the sleeve rod 8.4. The elastic coefficient of the second spring 8.3 is greater than that of the first spring 10. One end of the second spring 8.3 is fixed to the inner bottom of the sleeve rod 8.4, and the other end is fixed to the end of the fixed rod 8.1 located inside the sleeve rod 8.4. When the second spring 8.3 is in its natural state, the end of the fixed rod 8.1 connected to the second spring 8.3 is located inside the sleeve rod 8.4. In this embodiment, since the elastic coefficient of the second spring 8.3 is greater than that of the first spring 10, it can not only prevent the spring telescopic rod 8 from forming a rigid support for the pipeline when the water conservancy pipeline vibrates, but also prevent the left and right ends of the support plate 7 from moving with the middle part during the process of clamping the pipeline, thereby ensuring that the left and right ends of the support plate 7 can be tightly attached to the outer wall of the pipeline.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, both the end of the fixing rod 8.1 located outside the sleeve rod 8.4 and the closed end of the sleeve rod 8.4 are provided with hinge holes. The fixing rod 8.1 is mounted on the support plate 7 through the hinge holes and via a pivot or hinge seat. The sleeve rod 8.4 is mounted on the arc plate 4 through the hinge holes and via a pivot or hinge seat. The end of the fixing rod 8.1 located inside the sleeve rod 8.4 is fixed with a limiting block 8.2 to prevent the fixing rod 8.1 from sliding out of the sleeve rod 8.4. The other end of the second spring 8.3 is fixed to the limiting block 8.2.

[0026] In this embodiment, the fixing plate 1 is first fixed to the ground using anchor rods, bolts, etc., and then the water pipe is placed on the support plate 7 below. Then, the arc plate 4, which is not directly connected to the support column 3, is placed on the water pipe and the support plate 7 connected to the arc plate 4 is attached to the top of the water pipe. Then, the connecting plates 5 at the left and right ends of the two arc plates 4 are connected by fastening bolts 6. During the tightening of the fastening bolts 6, the middle part of the two support plates 7 will gradually approach the corresponding arc plate 4 and the first spring 10 will be compressed. The left and right ends of the support plate 7 can gradually attach to the outer wall of the water pipe under the support of the spring telescopic rod 8 hinged to it, until the second spring 8.3 inside the spring telescopic rod 8 is also compressed to a certain extent. At this time, the water pipe is fixed. Example

[0027] This embodiment further illustrates the technology. A rubber pad is fixed to the contact surface between the support plate 7 and the water pipe. The rubber pad on the support plate 7 can increase the friction between the support plate 7 and the water pipe, thereby further improving the stability of the water pipe fixed on the device.
