Description

Anti-sway hydraulic pipeline hangers Technical Field

[0001] This utility model relates to the field of water conservancy pipeline hanger technology, and in particular to anti-sway water conservancy pipeline hanger. Background Technology

[0002] Water conservancy pipelines are tubular facilities used in water conservancy projects to transport fluid media such as water, wastewater, and slurry. They are widely used in irrigation, water supply, drainage, sewage treatment, and hydropower generation. Their performance and design directly affect the safety, reliability, and operational efficiency of water conservancy systems. In the field of water conservancy pipeline installation, pipe hangers are key components for supporting and fixing water conservancy pipelines, and their stability directly affects the safe operation of the pipeline system.

[0003] A search revealed that patent document CN211010154U discloses a water pipe support bracket, including a support base. Support plates are fixedly connected to the upper surfaces of both ends of the support base. Each support plate is fixedly connected to a first fixing block via a buffer mechanism. The two first fixing blocks are fixedly connected to the same lower fixing half-ring. An upper fixing half-ring is provided at the upper end of the lower fixing half-ring.

[0004] The aforementioned pipe supports and hangers can mitigate the vertical impact force caused by water flow inside the pipe by setting up a buffer mechanism, using buffer rods and buffer springs, thereby preventing impact on the support rods and preventing the support rods from shaking due to impact and thus falling off.

[0005] However, the above-mentioned pipe supports and hangers still have the following technical problems during use:

[0006] Most hangers only achieve unidirectional fixation in the horizontal or vertical direction, making it difficult to form three-dimensional constraints and clamp and fix water pipes from multiple angles. For example, the traditional "double-sided clamping" structure cannot provide support for the bottom of the pipe. The weight of the pipe may cause stress concentration at the bottom connection of the hanger, which can easily lead to structural fatigue after long-term use, resulting in a reduction in the fixing effect on the water pipe. Summary of the Invention

[0007] The purpose of this utility model is to solve the problems in the prior art by proposing a three-dimensional clamping structure with "both sides + top" to significantly improve the anti-swaying ability of a hydraulic pipeline hanger.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Anti-sway hydraulic pipeline hangers include:

[0010] The hanging frame is provided with a horizontal fixing mechanism, a vertical fixing mechanism and a bottom adsorption mechanism inside;

[0011] The transverse fixing mechanism includes lead screws rotatably connected to the inner walls of both sides of the hanger frame. The threads on the two lead screws are in opposite directions. Each lead screw is threaded with a threaded sleeve. A transverse clamping plate is fixedly connected to one end of each threaded sleeve near the center of the hanger frame. Control motors for driving the lead screws to rotate are fixedly connected to the outer walls of both sides of the hanger frame. A PLC controller is fixedly connected to the inner bottom wall of the hanger frame. The PLC controller is used to drive the two control motors to work synchronously.

[0012] Preferably, a limiting block is fixedly connected to the lower end of the threaded sleeve, and a limiting rod is fixedly connected to the inner side wall of the hanger frame, with the limiting rod slidingly connected to the limiting block.

[0013] Preferably, the longitudinal fixing mechanism includes a guide rod assembly fixedly connected to the inner walls of both sides of the hanger frame. The upper end of the threaded sleeve is fixedly connected to a first rack via a first connecting block. A transmission gear is hinged to the inner walls of both sides of the hanger frame via a hinge rod. A second rack that slides horizontally is provided above the transmission gear. The second rack is close to a moving plate on the inner wall of the hanger frame. The guide rod assembly includes two guide rods that slide through and are slidably connected to the moving plate. The lower and upper parts of the transmission gear mesh with the first rack and the second rack at corresponding positions, respectively. A lifting block is slidably installed vertically inside the hanger frame. The lower end of the lifting block is fixedly connected to two symmetrically arranged first hinge seats. The upper end of each second rack is fixedly connected to a second hinge seat. A connecting rod is hinged between the first hinge seat and the corresponding second hinge seat. The lower end of the lifting block is fixedly connected to a longitudinal clamping plate via a second connecting block.

[0014] Preferably, a vertical rod is fixedly connected to the upper end of the lifting block, and the vertical rod is slidably connected to the top wall of the hanger frame.

[0015] Preferably, the bottom adsorption mechanism includes an annular telescopic airbag fixedly connected between the lifting block and the top wall of the hanging frame. The bottom wall of the hanging frame is fixedly connected to an arc-shaped support block through a third connecting block. A negative pressure chamber is opened inside the arc-shaped support block. An air supply pipe is fixedly connected to one side wall of the annular telescopic airbag. The air supply pipe connects the annular telescopic airbag and the negative pressure chamber. Multiple sets of linearly arrayed adsorption holes are opened at the upper end of the arc-shaped support block. The negative pressure chamber is connected to the outside through multiple sets of adsorption holes.

[0016] Preferably, the annular telescopic airbag has an elastic element inside.

[0017] Preferably, a sealing rubber ring is fixedly connected to the inner arc surface of the arc-shaped support block.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This utility model sets up a horizontal fixing mechanism and a vertical fixing mechanism. The PLC controller synchronously drives the lead screws on both sides to rotate, which drives the horizontal clamping plate to clamp the two sides of the pipe, ensuring horizontal stability. At the same time, the gear and rack transmission is used to link the horizontal clamping action with the vertical lifting action, so that the vertical clamping plate automatically presses down on the upper surface of the pipe to achieve vertical fixation, forming a three-dimensional clamping structure of "both sides + top", which significantly improves the anti-shaking ability.

[0020] 2. This utility model, by setting a bottom adsorption mechanism, can form negative pressure through the stretching of the annular telescopic airbag during the clamping and fixing process. The bottom of the pipe is fixed to the arc-shaped support block by the adsorption hole. The negative pressure adsorption method can improve the fixing effect of the water conservancy pipeline. At the same time, with the buffering effect of the sealing rubber ring, it can effectively absorb vibration energy and reduce the relative displacement between the pipe and the hanger.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Referring to Figures 1 to 3, the anti-sway hydraulic pipeline hanger includes:

[0033] The hanging frame 1 has a horizontal fixing mechanism 2, a vertical fixing mechanism 4 and a bottom adsorption mechanism 6 inside the hanging frame 1;

[0034] Specifically, before use, the hanger frame 1 can be fixed to the installation position by tightening the bolts.

[0035] The transverse fixing mechanism 2 includes lead screws 21 rotatably connected to the inner walls of both sides of the hanger frame 1. Each lead screw 21 is threaded with a threaded sleeve 22. A transverse clamping plate 23 is fixedly connected to one end of each threaded sleeve 22 near the center of the hanger frame 1. Control motors 24 for driving the lead screws 21 to rotate are fixedly connected to the outer walls of both sides of the hanger frame 1. A PLC controller 25 is fixedly connected to the inner bottom wall of the hanger frame 1. The PLC controller 25 is used to drive the two control motors 24 to work synchronously.

[0036] Specifically, a limiting block 31 is fixedly connected to the lower end of the threaded sleeve 22, and a limiting rod 3 is fixedly connected to the inner side wall of the hanger frame 1. The limiting rod 3 is slidably connected to the limiting block 31. Through the limiting rod 3 and the limiting block 31, the threaded sleeve 22 can be limited, preventing the threaded screw 21 from rotating and causing the threaded sleeve 22 to rotate, so that the threaded sleeve 22 can only move in the horizontal direction.

[0037] Specifically, the threads on the two lead screws 21 are in opposite directions, so that when the two lead screws 21 rotate in the same direction, the threaded sleeves 22 on the two lead screws 21 move closer to each other or further away from each other.

[0038] Specifically, the control motor 24 is a servo motor of model 80DK-M07725, which facilitates the control of the forward and reverse rotation of the lead screw 21.

[0039] When the two control motors 24 (synchronously driven by the PLC controller 25) rotate in the forward direction, the two lead screws 21 rotate synchronously, driving the threaded sleeve 22 to move along the lead screw 21 toward the center of the hanger frame 1, pushing the transverse clamping plate 23 to clamp the outer wall of the pipe; when rotating in the reverse direction, the threaded sleeve 22 drives the transverse clamping plate 23 to loosen.

[0040] The longitudinal fixing mechanism 4 includes guide rod assemblies 41 fixedly connected to the inner walls of both sides of the hanger frame 1. A first rack 42 is fixedly connected to the upper end of the threaded sleeve 22 via a first connecting block. Transmission gears 43 are hinged to the inner walls of both sides of the hanger frame 1 via hinge rods. A second rack 44, sliding horizontally, is positioned above the transmission gear 43. The second rack 44 is close to a movable plate 45 on the inner wall of the hanger frame 1. The guide rod assembly 41 includes two guide rods that slide through and are slidably connected to the movable plate 45. The transmission gear... The lower and upper parts of 43 respectively mesh with the first rack 42 and the second rack 44 at corresponding positions. A lifting block 46 is slidably installed in the vertical direction inside the hanger frame 1. The lower end of the lifting block 46 is fixedly connected to two symmetrically arranged first hinge seats 47. The upper end of each second rack 44 is fixedly connected to a second hinge seat 48. A connecting rod 49 is hinged between the first hinge seat 47 and the corresponding second hinge seat 48. The lower end of the lifting block 46 is fixedly connected to a longitudinal clamping plate 410 through a second connecting block.

[0041] Specifically, a vertical rod 5 is fixedly connected to the upper end of the lifting block 46. The vertical rod 5 is slidably connected to the top wall of the hanger frame 1. The vertical rod 5 can limit the position of the lifting block 46 to prevent the position of the lifting block 46 from deflecting, which would prevent the longitudinal clamping plate 410 below the lifting block 46 from effectively clamping the water pipe.

[0042] When the first rack 42 at the upper end of the threaded sleeve 22 moves synchronously with the transverse clamping plate 23, it drives the transmission gear 43 to rotate (gear and rack meshing), thereby causing the upper second rack 44 to slide horizontally. The second rack 44 is slidably connected to the guide rod assembly 41 through the moving plate 45 to ensure the stability of horizontal movement. The second hinge seat 48 at the upper end of the second rack 44 is hinged to the first hinge seat 47 of the lifting block 46 through the connecting rod 49. When the second rack 44 moves horizontally, the connecting rod 49 pushes the lifting block 46 to rise and fall in the vertical direction, so that the longitudinal clamping plate 410 is tightly attached to the upper surface of the pipe, realizing vertical clamping and fixing. During this process, the transverse and longitudinal clamping actions are linked, and the clamping force can be automatically adjusted according to the pipe diameter. No additional drive source is required, and it can clamp and fix both sides and the upper end of the water pipe at the same time, improving the clamping and fixing effect.

[0043] The bottom adsorption mechanism 6 includes an annular telescopic airbag 61 fixedly connected between the lifting block 46 and the inner top wall of the hanger frame 1. An arc-shaped support block 62 is fixedly connected to the inner bottom wall of the hanger frame 1 through a third connecting block. A negative pressure chamber is opened inside the arc-shaped support block 62. An air supply pipe 63 is fixedly connected to one side wall of the annular telescopic airbag 61. The air supply pipe 63 connects the annular telescopic airbag 61 and the negative pressure chamber. Multiple sets of linearly arrayed adsorption holes 64 are opened at the upper end of the arc-shaped support block 62. The negative pressure chamber is connected to the outside through multiple sets of adsorption holes 64.

[0044] Specifically, the annular telescopic airbag 61 is equipped with an elastic element inside. Through the elastic element, when the lifting block 46 moves upward, the annular telescopic airbag 61 can be contracted and reset under the action of elastic force, thereby increasing the air pressure in the negative pressure chamber and restoring it to the initial atmospheric pressure.

[0045] Specifically, a sealing rubber ring is fixedly connected to the inner arc surface of the arc-shaped support block 62. The sealing rubber ring ensures that the negative pressure chamber is sealed during the process of the water pipe being tightly attached to the arc-shaped support block 62 and being clamped.

[0046] When the lifting block 46 is driven downward by the longitudinal fixing mechanism 4, it stretches the annular telescopic airbag 61 (the internal elastic element is stretched), and the airbag expands. Air is drawn from the negative pressure chamber of the arc-shaped support block 62 through the air supply pipe 63, creating a negative pressure in the negative pressure chamber. At this time, the adsorption hole 64 adsorbs the bottom of the pipe, and together with the inner arc surface of the arc-shaped support block 62, the pipe is firmly fixed to the bottom of the hanger. When it is necessary to release the pipe, the lifting block 46 moves upward, and the elastic element pushes the annular telescopic airbag 61 to contract, forcing outside air into the negative pressure chamber through the air supply pipe 63, restoring the normal pressure state, and the adsorption effect is released. The sealing rubber ring of the arc-shaped support block 62 also plays the role of buffering vibration and enhancing sealing.

[0047] The functional principle of this utility model can be explained through the following operation methods:

[0048] Pipe installation: Place the pipe on the arc-shaped support block 62, start the control motor 24, and the PLC controller 25 synchronously drive the lead screws 21 on both sides to rotate, and the horizontal clamping plate 23 moves horizontally to clamp the outer wall of the pipe.

[0049] Longitudinal linkage: During the transverse clamping process, the threaded sleeve 22 drives the first rack 42 to move, and drives the lifting block 46 to descend through the transmission gear 43 and the second rack 44, and the longitudinal clamping plate 410 presses down on the upper surface of the pipe simultaneously.

[0050] Negative pressure adsorption: The lifting block 46 moves down and stretches the annular telescopic airbag 61 to form negative pressure. The adsorption hole 64 fixes the bottom of the pipe to achieve three-dimensional anti-sway fixation.

[0051] Disassembling the pipe: Control motor 24 to rotate in the opposite direction, the horizontal clamping plate 23 is released, and at the same time the lifting block 46 moves upward. The elastic element resets the airbag, the negative pressure chamber is depressurized, and the pipe can be removed.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
