Description

Technical Field

[0001] This invention belongs to the field of pipeline protection technology, and in particular relates to a vibration damping device for fixing ultra-high-rise concrete pump pipes. Background Technology

[0002] Concrete is used in almost all construction projects, including building construction, municipal engineering, transportation engineering, and water conservancy projects. The two most common methods for concrete pouring are truck-mounted pumps and trailer pumps (ground pumps). Due to technical limitations, the longest truck-mounted pump arm on the market is currently 72 meters. Trailer pumps are more commonly used for construction in high-rise buildings and in areas with limited space.

[0003] Concrete pumping is an indispensable key link in the construction of super high-rise buildings. However, the existing concrete conveying technology has significant technical defects when applied to super high-rise buildings. Specifically, during the concrete conveying process, the periodic squeezing and suction of the pump will generate large pressure pulsations, which will lead to obvious vibration of the pump pipe. Since the pump pipes of super high-rise buildings are usually large in vertical height, heavy in weight, and have high conveying pressure, this vibration phenomenon is particularly prominent.

[0004] Prolonged vibration inevitably leads to loosening of the pump pipe and its connections, such as flange connections and clamp connections, and may even cause fatigue cracks. Such loosening and cracks will not only significantly reduce the reliability of the pump pipe connection and affect the pumping efficiency, but also seriously affect the service life of the pump pipe itself, increase maintenance costs and replacement frequency. In addition, loosening and cracks at the connection may also cause concrete leakage, resulting in environmental pollution and even safety accidents, bringing great inconvenience and hidden dangers to the transportation process of ultra-high-rise concrete.

[0005] Based on this, the present invention designs a vibration damping device for fixing concrete pump pipes in ultra-high-rise buildings to solve the above problems. Summary of the Invention

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

The pump pipe body is fitted with two first locking mechanisms and one second locking mechanism. A hydraulic buffer mechanism is connected below the second locking mechanism, and an elastic buffer mechanism is connected below the first locking mechanism. A connecting seat is fixedly connected below the hydraulic buffer mechanism.

A telescopic rod is fixedly connected to the lower part of the intermediate plate. The telescopic rod is fixedly connected to the base.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In this invention, a second arc-shaped seat, a vertical rod, a first buffer spring, a connecting valve, a gear, a rack, and an amplitude sensor are used. When the pump pipe experiences significant vibration, the amplitude sensor monitors the vibration amplitude in real time. Once the amplitude exceeds a preset threshold, the controller immediately activates the electro-hydraulic rod, driving the rack upwards, which in turn rotates the gear and the connecting valve, increasing the opening of the connecting valve. This increases the flow rate and speed of the hydraulic oil in the connecting valve and connecting pipe, thereby pushing the second arc-shaped seat, the vertical rod, and the first pressure plate downwards. During this process, the first pressure plate squeezes the hydraulic oil between the first and second pressure plates, while the second pressure plate squeezes the hydraulic oil in the hydraulic cylinder, allowing it to enter the reservoir through the intermediate pipe and the connecting valve. The downward movement of the second arc-shaped seat compresses the first buffer spring, causing elastic deformation. The combined effect of the hydraulic oil flow and the elastic deformation of the first buffer spring efficiently absorbs vibration energy, significantly reducing the vibration amplitude. The buffer and shock absorption system of this invention is highly flexible. Through precise control of the electro-hydraulic rod by the controller, the flow of hydraulic oil can be finely adjusted to adapt to vibrations of varying amplitudes. This flexible and adaptable buffering mechanism enables the invention to cope with various complex working conditions and effectively protect the pump pipe from vibration damage. This invention converts vibration energy into hydraulic energy and elastic potential energy through the flow of hydraulic oil and the elastic deformation of the spring. This energy is then dissipated through the throttling of the hydraulic oil and the damping effect of the spring, thus achieving effective dissipation of vibration energy. This energy dissipation mechanism makes the shock absorption effect of this invention more significant, effectively reducing the impact and wear of vibration on the pump pipe connection. Through effective vibration suppression and buffering, this invention significantly reduces the risk of loosening and cracking at the pump pipe connection, thereby effectively extending the service life of the pump pipe, reducing maintenance costs and replacement frequency, and improving economic efficiency.

[0020] 2. In this invention, an elastic buffer mechanism is adopted. During the downward movement of the first arc-shaped seat, the second buffer spring is compressed, thereby achieving effective buffering of vibration. When the second buffer spring is compressed, it gradually increases the reaction force on the first arc-shaped seat, so that the clamping pressure on both sides of the pump pipe gradually increases with displacement, thereby improving the absorption efficiency of vibration energy. This structure not only enhances the gradualness of buffering, but also effectively prevents structural damage caused by the instantaneous transmission of impact force. By combining the hydraulic shock absorption structure with the elastic buffer mechanism on both sides, multi-point distributed shock absorption is achieved, which can evenly distribute the vibration energy to multiple damping units, greatly improving the shock absorption range and buffering effect of the entire pump pipe fixing system, ensuring that the pump pipe can obtain sufficient and stable shock absorption support in a large stress area, thereby significantly improving its operational stability and service life.

[0021] 3. In this invention, a telescopic rod, side plate, extrusion rod, and guide hole are used. During the movement of the extrusion rod, the guide hole guides the side plate upward, thereby causing the intermediate plate to move. The movement of the intermediate plate will further compress the second buffer spring and damping connector, changing their initial compression state and forming a preload effect. This mechanism design allows the hydraulic buffer mechanism to absorb vibration energy while converting some of the energy into a driving force to control the initial compression degree of the first buffer spring. The first buffer spring, in a rapid compression state, can provide rapid and powerful energy absorption for sudden large-amplitude vibrations, improving the overall system's response speed to instantaneous impacts. This composite linkage structure gives the buffering and shock absorption effect good flexibility and variability. It can dynamically adjust the buffering mechanism for different vibration intensities and expand the system's adaptability range, further improving the stability and durability of the pump pipe fixing device.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a technical solution: a vibration damping device for fixing a concrete pump pipe in a high-rise building, comprising a positioning seat 2 for installing a pump pipe body 1, two first locking mechanisms 3 and one second locking mechanism 4 being fitted around the pump pipe body 1, a hydraulic buffer mechanism 5 connected below the second locking mechanism 4, an elastic buffer mechanism 11 connected below the first locking mechanism 3, a connecting seat 6 fixedly connected below the hydraulic buffer mechanism 5, a connecting pipe 7 communicating with the front of the hydraulic buffer mechanism 5, a liquid storage tank 9 communicating with the bottom end of the connecting pipe 7, an extension plate 10 fixedly connected below the liquid storage tank 9, and the connecting pipe... 7 is provided with an adjustable valve mechanism 8 connected to the extension plate 10. The extension plate 10 is fixedly connected to the front of the connecting seat 6. The elastic buffer mechanism 11 is connected to the base 12. The first guide block 14 is fixedly installed under the base 12. The connecting seat 6 is fixedly connected to the second guide block 16. The first guide block 14 and the second guide block 16 are slidably connected to the positioning seat 2. The left and right sides of the inner wall of the positioning seat 2 are connected to the third buffer spring 15. The third buffer spring 15 is fixedly connected to the first guide block 14. The second locking mechanism 4 is equipped with an amplitude sensor 18.

[0034] The first guide block 14 and the second guide block 16 can slide within the positioning seat 2, and during the sliding process, they will squeeze or stretch the third buffer spring 15 to buffer and protect the pump pipe body 1 from horizontal vibration.

[0035] Specifically, such as Figure 7 As shown, the first locking mechanism 3 includes a first arc-shaped seat 31 fixedly connected to the top of the elastic buffer mechanism 11. The front and rear sides of the first arc-shaped seat 31 are provided with first connecting grooves 32. A first rotating clamping plate 33 is hinged in the first connecting groove 32. A first locking bolt 34 is threaded through and connected to the two first rotating clamping plates 33. The first rotating clamping plate 33 is located outside the pump pipe body 1.

[0036] Specifically, such as Figure 1-3 As shown, the second locking mechanism 4 includes a second arc-shaped seat 41 fixedly connected to the top of the hydraulic buffer mechanism 5. The front and rear sides of the second arc-shaped seat 41 are provided with second connecting grooves 42. A second rotating clamping plate 43 is hinged in the second connecting groove 42. A second locking bolt 44 is threaded through and connected to the two second rotating clamping plates 43. The second rotating clamping plates 43 are located outside the pump pipe body 1. An amplitude sensor 18 is installed under the second arc-shaped seat 41. The amplitude sensor 18 is used to detect the vertical vibration amplitude of the pump pipe body 1.

[0037] Specifically, such as Figure 5-6 As shown, the hydraulic buffer mechanism 5 includes a hydraulic cylinder 51, which is fixedly connected to the connecting seat 6. A first pressure plate 52 and two second pressure plates 56 are slidably connected inside the hydraulic cylinder 51. A vertical rod 53 is fixedly connected to the first pressure plate 52. The vertical rod 53 passes through and is slidably connected to the hydraulic cylinder 51. One end of the vertical rod 53 located outside the hydraulic cylinder 51 is fixedly connected to the lower surface of the second arc-shaped seat 41. A first buffer spring 54 is sleeved on the vertical rod 53. The two ends of the first buffer spring 54 are fixedly connected to the lower part of the second arc-shaped seat 41 and the upper part of the hydraulic cylinder 51, respectively.

[0038] A crossbar 57 is connected to each of the two second pressure plates 56 on the side away from each other. A connecting sleeve 58 is slidably connected to the outside of the crossbar 57. The connecting sleeve 58 is connected through the side of the hydraulic cylinder 51. The end of the crossbar 57 located outside the hydraulic cylinder 51 is fixedly connected to the outside of the elastic buffer mechanism 11. The hydraulic cylinder 51 is connected to the connecting pipe 7. An air hole 55 is opened on the side of the hydraulic cylinder 51.

[0039] The pump body 1 vibrates significantly. The vertical vibration compresses the second arc-shaped seat 41, the vertical rod 53, and the first pressure plate 52 to move downwards. As the first pressure plate 52 moves downwards, it compresses the hydraulic oil between the first pressure plate 52 and the second pressure plate 56. The flowing hydraulic oil acts on the second pressure plate 56, controlling the movement of the second pressure plate 56 while compressing the hydraulic oil in the hydraulic cylinder 51 to enter the reservoir 9 through the intermediate pipe and connecting valve 85. When the second arc-shaped seat 41 moves downwards, it compresses and deforms the first buffer spring 54. The flow of hydraulic oil and the deformation of the first buffer spring 54 both absorb the energy of the vibration.

[0040] Specifically, such as Figure 2-4 and Figure 8 As shown, the adjustable valve mechanism 8 includes a connecting valve 85 and a support plate 81 fixedly connected to the front of the connecting seat 6. An electric hydraulic rod 82 is fixedly connected to the support plate 81, and a toothed rod 83 is fixedly connected to the top of the electric hydraulic rod 82.

[0041] A connecting valve 85 is located outside the connecting pipe 7. A gear 84 is fixedly connected to the outside of the connecting valve 85. The gear 84 meshes with the outside of the rack 83. The connecting pipe 7 is Y-shaped. A controller is connected to the outside of the amplitude sensor 18. The controller is used to control the extension and retraction of the electro-hydraulic rod 82.

[0042] When the amplitude sensor 18 detects that the amplitude exceeds the threshold, it controls the electric hydraulic rod 82 to work through the controller. The electric hydraulic rod 82 controls the rack 83 to move upward. The rack 83 controls the gear 84 and the connecting valve 85 to rotate. The opening of the connecting valve 85 increases, which increases the flow of hydraulic oil in the connecting valve 85 and the connecting pipe 7, and speeds up the flow of hydraulic oil.

[0043] The positioning seat 2 has two threaded seats 17 fixedly connected to both the front and rear sides. The base 12 has a fixing rod 13 fixedly connected to the connecting seat 6 on its side. The cross-sectional shape of the first guide block 14 and the second guide block 16 is T-shaped to ensure that the first guide block 14 and the second guide block 16 perform horizontal linear movements within the positioning seat 2.

[0044] Specifically, such as Figure 2 and Figure 7 As shown, the elastic buffer mechanism 11 includes an intermediate plate 111 and four second buffer springs 113 fixedly connected to the lower surface of the first arc-shaped seat 31. The intermediate plate 111 is fixedly connected to the bottom end of the second buffer springs 113. Four damping connectors 112 located inside the second buffer springs 113 are fixedly connected to the intermediate plate 111. The damping connectors 112 are fixedly connected to the bottom of the first arc-shaped seat 31.

[0045] Two side plates 114 are fixedly connected to the middle plate 111. The side plates 114 have guide holes 115 on the outside. A pressing rod 116 is slidably connected in the guide holes 115. The pressing rod 116 is fixedly connected to one end of the crossbar 57. A telescopic rod 117 is fixedly connected to the middle plate 111. The telescopic rod 117 is fixedly connected to the base 12.

[0046] While the compression rod 116 moves, it controls the side plate 114 and the middle plate 111 to move upward through the guide hole 115. During the movement of the middle plate 111, it will compress the second buffer spring 113 and the damping connector 112, causing a change in their initial compression degree. The change in the initial compression degree of the second buffer spring 113 will adjust its absorption efficiency of vibration energy, making it convenient to adjust the damping efficiency according to the vibration. The telescopic rod 117 can ensure the stability of the middle plate 111 in the vertical direction.

[0047] Working principle and usage:

[0048] The positioning seat 2 is installed in the designated position through the threaded seat 17, and the pump pipe body 1 is passed between the first rotating clamp 33 and the second rotating clamp 43. The two first rotating clamps 33 and the two second rotating clamps 43 are fastened by the first locking bolt 34 and the second locking bolt 44. During the concrete transfer process, the pump pipe body 1 experiences significant vibration. The vertical vibration compresses the second arc-shaped seat 41, the vertical rod 53, and the first pressure plate 52, causing them to move downwards. As the first pressure plate 52 moves downwards, it also compresses the space between the first pressure plate 52 and the second pressure plate 56. The hydraulic oil moves, and the flowing hydraulic oil acts on the second pressure plate 56. While controlling the movement of the second pressure plate 56, it squeezes the hydraulic oil in the hydraulic cylinder 51 and enters the reservoir 9 through the intermediate pipe and connecting valve 85. When the second arc-shaped seat 41 moves downward, it will squeeze the first buffer spring 54 to deform. When the first pressure plate 52 moves, it will push the hydraulic oil to flow and the second pressure plate 56 to move. During the movement, the friction between the hydraulic cylinder 51 will consume energy. The deformation of the first buffer spring 54 will absorb the energy of vibration and play a significant role in shock absorption.

[0049] As the first arc-shaped seat 31 moves downward, it compresses the second buffer spring 113, which shortens. The second buffer spring 113 buffers the vibration received by the first arc-shaped seat 31. As the vibration intensity increases, the movement becomes larger, and the support force of the elastic buffer mechanism 11 on the pump pipe body 1 increases accordingly, so that the pressure on both sides of the pump pipe body 1 gradually increases, thereby enhancing the absorption capacity of vibration. Hydraulic damping and elastic damping form multi-point damping, dispersing vibration energy and ensuring that the pump pipe body 1 can receive effective damping support over a large area.

[0050] While the second pressure plate 56 moves, the extrusion rod 116 is moved by the crossbar 57. While the extrusion rod 116 moves, the side plate 114 and the middle plate 111 are moved upward by the guide hole 115. During the movement of the middle plate 111, it will extrude the second buffer spring 113 and the damping connector 112, causing a change in their initial compression degree. The vibration energy received by the hydraulic buffer mechanism 5 can be converted into a change in the initial compression degree of the first buffer spring 54.

[0051] When the pump pipe body 1 experiences significant vibration, the amplitude sensor 18 detects that the amplitude exceeds the threshold. The controller then activates the electro-hydraulic rod 82, which in turn moves the rack 83 upwards. The rack 83 then controls the gear 84 and connecting valve 85 to rotate, increasing the opening of the connecting valve 85. This increases the flow rate of hydraulic oil within the connecting valve 85 and connecting pipe 7, accelerating the movement of the first pressure plate 52 and the second pressure plate 56. This allows for rapid absorption of strong vibration energy. Furthermore, the first buffer spring 54, initially compressed rapidly, quickly absorbs energy from the significantly vibrating pump pipe body 1. The buffering and shock absorption effect is more flexible and adaptable, with a more efficient and significant energy consumption during the buffering process. It can adapt flexibly to different vibration amplitudes, effectively reducing the impact of vibration on the connection between the pump pipe body 1 and the concrete pump, ensuring the normal service life of the pump pipe body 1 and the delivery of concrete.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
