Abstract
Description
Technical Field
[0001] This invention relates to the field of building engineering technology, specifically to a novel pump pipe vibration reduction and noise reduction device. Background Technology
[0002] During concrete pouring, the vibration and noise from pump pipes can adversely affect the normal operation of the equipment and the surrounding environment. Pump pipe vibration can lead to pipe fatigue and damage, affecting equipment lifespan and safety. Noise can impact the surrounding environment and human health, and may even cause pouring interruptions due to environmental factors, resulting in structural cold joints and affecting the quality of the concrete pouring. Therefore, developing and using effective pump pipe vibration reduction and noise reduction devices is of great significance.
[0003] Currently, commonly used pump pipe vibration reduction and noise reduction devices include:
[0004] (1) Dampers: Dampers installed on pump pipes or brackets absorb vibrations and reduce noise;
[0005] (2) Vibration damping pad: Vibration dampers can be installed between the concrete pump pipe and the support to reduce pump pipe vibration and reduce noise;
[0006] (3) Noise reduction cover: Installing a noise reduction cover around the pump pipe can isolate the noise inside the cover and reduce the noise transmitted to the surrounding environment;
[0007] (4) Buffer material: Adding buffer material, such as rubber pads or foam plastic, between the pump pipe and the support can reduce vibration and noise.
[0008] Existing technologies have significant limitations, mainly:
[0009] 1) Different vibration reduction and noise reduction technologies have different effectiveness for vibration and noise within a specific frequency range. Therefore, it is necessary to select the appropriate technology according to the specific situation. The vibration and noise characteristics are different for different buildings, floors, locations and construction stages. As the pumping height increases, the vibration and noise characteristics will also change. Existing technologies cannot adapt to different application scenarios and working conditions, and cannot dynamically adjust control parameters as construction progresses.
[0010] 2) Existing technologies cannot achieve vibration reduction in pump pipes in three directions, especially for sections where horizontal and vertical pump pipes transition, as well as pump pipes at bends, where the vibration reduction and noise reduction effects are not obvious.
[0011] 3) Some technologies may have a negative impact on the operation of concrete pump pipes, and may hinder normal on-site construction due to their large space occupation and special installation location.
[0012] 4) Existing technologies require specific installation methods and are adapted to specific usage frequencies in different application scenarios and working conditions, making it difficult to adopt modular construction designs and recycle them.
[0013] Therefore, existing pump pipe vibration reduction and noise reduction devices are not very reliable due to the aforementioned technical problems. It is evident that improving the reliability of pump pipe vibration reduction and noise reduction devices is a problem that needs to be solved in this field. Summary of the Invention
[0014] In view of the technical problem of low reliability of existing pump pipe vibration reduction and noise reduction devices, the purpose of this invention is to provide a new type of pump pipe vibration reduction and noise reduction device, which can dynamically adjust parameters according to different scenarios and working conditions and can realize vibration reduction of pump pipe in three directions, greatly improving the reliability of the pump pipe vibration reduction and noise reduction device and effectively overcoming the problems existing in the prior art.
[0015] To achieve the above objectives, the present invention provides a novel pump pipe vibration reduction and noise reduction device, comprising a vertical pump pipe, a rubber layer, a clamp with an annular plate, and several vibration reduction and noise reduction modules; the rubber layer wraps around the side wall of the vertical pump pipe, and the clamp with an annular plate is assembled around the rubber layer; the several vibration reduction and noise reduction modules are correspondingly disposed on the cylindrical wall of the clamp with an annular plate; each vibration reduction and noise reduction module includes a counterweight box, a vertical spring module, a horizontal spring module, and several insertable counterweights; the several insertable counterweights are inserted into the counterweight box to provide mass to the counterweight box; the two ends of the vertical spring module are respectively connected to the bottom end of the counterweight box and the annular plate of the clamp with an annular plate; the two ends of the horizontal spring module are respectively connected to the side wall of the counterweight box and the cylindrical wall of the clamp with an annular plate.
[0016] Furthermore, the rubber layer is divided into two equal and symmetrical semi-circular parts, which respectively make physical contact with the vertical pump pipe and form a complete wrap.
[0017] Furthermore, the ring-shaped clamp is divided into two equal and symmetrical parts, which are respectively fitted and installed to the two parts of the rubber layer, and connected by locking parts on both sides to form a whole.
[0018] Furthermore, the clamp with an annular plate, once formed as a whole, includes a clamp cylinder and an annular plate; the annular plate is disposed at the bottom end of the clamp cylinder.
[0019] Furthermore, the counterweight box may be equipped with vertical metal positioning rods arranged in a matrix, and the insertable counterweight block is sleeved on the metal positioning rods to form a limiting structure for the insertable counterweight block.
[0020] Furthermore, the vertical spring module includes a vertical spring slide rail, a perforated spring end plate, a vertical spring, a vertical spring slider, and a limiting bar;
[0021] The vertical spring slide rail is located at the bottom of the counterweight box, and the vertical spring slider is assembled with the vertical spring slide rail on the counterweight box and can move along the slide rail direction.
[0022] The vertical spring is connected and fixed at both ends to the perforated spring end plate and the vertical spring slider, respectively. The vertical spring can be compressed and stretched as the vertical relative position of the perforated spring end plate and the vertical spring slider changes.

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.
[0044] In view of the technical problem of low reliability of existing pump pipe vibration reduction and noise reduction devices, the purpose of this invention is to provide a new type of pump pipe vibration reduction and noise reduction device, which can dynamically adjust parameters according to different scenarios and working conditions and can realize vibration reduction of pump pipe in three directions, greatly improving the reliability of the pump pipe vibration reduction and noise reduction device.
[0045] The novel pump pipe vibration reduction and noise reduction device provided by this invention is described in [reference needed]. Figures 1-3 It includes a vertical pump pipe 1, a rubber layer 2, a clamp with an annular plate 3, and several vibration reduction and noise reduction modules 4.
[0046] Furthermore, the rubber layer 2 is divided into two equal and symmetrical semi-circular parts, which respectively make physical contact with the vertical pump 1 pipe and form a complete wrap.
[0047] By directly contacting the rubber layer 2 with the vertical pump pipe 1 and forming a complete wrap, a certain buffer can be formed for the vertical pump pipe 1, and the vertical pump pipe 1 can be pre-damped.
[0048] A ring-shaped clamp 3 is assembled on the outside of the rubber layer 2. The ring-shaped clamp 3 is divided into two equal and symmetrical parts, which are respectively fitted and installed to the two parts of the rubber layer 2, and connected by locking parts on both sides to form a whole.
[0049] It should be noted that the specifications and dimensions of the rubber layer 2 and the ring-plate clamp 3 are determined according to the cross-sectional dimensions of the vertical pump pipe that needs vibration reduction, so as to ensure that they can be installed in close contact with the vertical pump pipe 1.
[0050] The thickness of rubber layer 2 also needs to be further determined based on the required vibration reduction strength in practice.
[0051] Locking parts are provided on both the cylindrical wall with the ring plate clamp 3 and the lower ring plate, which can be used to install the vibration reduction and noise reduction module 4 in different positions.
[0052] Several vibration damping and noise reduction modules 4 are set along the cylindrical wall of the ring-plate clamp 3 by means of locking components, but this solution does not limit the number of vibration damping and noise reduction modules 4 or the installation method on the cylindrical wall of the ring-plate clamp 3.
[0053] Therefore, in specific implementation, the number of vibration reduction and noise reduction modules can be determined according to the intensity and directionality requirements of vibration reduction. For example, if the vibration intensity in one direction is large while the intensity in another direction is negligible, the number of vibration reduction and noise reduction modules 4 can be reduced and concentrated in the direction with larger vibration intensity.
[0054] Alternatively, if the vibration intensity in each direction is small but evenly distributed, the number of vibration reduction and noise reduction modules 4 can be reduced by a factor of two but evenly distributed in each direction. For example, only four vibration reduction and noise reduction modules 4 can be retained in a distribution pattern with a 90-degree interval.
[0055] The number of vibration reduction and noise reduction modules 4 to be assembled is determined according to the intensity and direction requirements of vibration reduction. This can save costs and further enhance the vibration reduction effect.
[0056] Several vibration reduction and noise reduction modules 4 have the same structure, see [link / reference] Figure 1Each vibration reduction and noise reduction module 4 includes a counterweight box 41, a vertical spring module 42, a horizontal spring module 43, and an insertable counterweight block 44.
[0057] The counterweight box 41 is mainly used to hold the insertable counterweight 44. The insertable counterweight 44 is detachably installed inside the counterweight box 41. Different numbers of insertable counterweights 44 can provide different masses to the counterweight box 41, thereby adjusting the vibration reduction effect of the vibration reduction and noise reduction module 4.
[0058] by Figure 1 As shown in the example, each counterweight box 41 can be equipped with a total of 56 insertable counterweight blocks 44. By adjusting the number of insertable counterweight blocks 44 in different directions of the counterweight box 41, the vibration reduction and noise reduction effect of the device of the present invention can be further precisely adjusted and controlled without the number of vibration reduction and noise reduction modules 4 being fixed, so as to adapt to different application scenarios.
[0059] This solution does not limit the number of counterweights 44 inserted in the counterweight box 41. By inserting different numbers of insertable counterweights 44 into the counterweight box 41 in different positions, the vibration reduction and noise reduction effect of the device of the present invention can be further precisely adjusted and controlled.
[0060] Secondly, see Figures 4-5 The counterweight box 41 can be equipped with vertical metal positioning rods 411 arranged in a matrix. At the same time, through holes are provided on the insert-type counterweight blocks 44. The through holes on the insert-type counterweight blocks 44 are connected to the metal positioning rods 411 in the counterweight box 41. The insert-type counterweight blocks 44 are sleeved on the metal positioning rods 411. The metal positioning rods 411 are used to position and restrict the movement of each insert-type counterweight block 44, ensuring that the mass source in the vibration reduction and noise reduction module 4 has a stronger overall integrity.
[0061] A horizontal spring module 43 and a vertical spring module 42 are provided on two adjacent sides of the counterweight box 41. The horizontal spring module 43 is connected to the locking part reserved on the cylindrical wall of the ring plate clamp 3 through a locking member. The vertical spring module 42 is connected to the locking part reserved on the ring plate clamp 3 through a locking member.
[0062] Further, see Figure 6 The vertical spring module 42 includes a vertical spring slide rail 413, a perforated spring end plate 421, a vertical spring 422, a vertical spring slider 423, and a limiting rod 424.
[0063] See Figure 7 The vertical spring slide rail 413 is located on one end face of the counterweight box 41 opposite to the annular plate. The vertical spring slider 413 is assembled with the vertical spring slide rail 413 on the counterweight box 41 and is able to move along the direction of the spring slide rail 413.
[0064] The two ends of the vertical spring 422 are connected and fixed to the perforated spring end plate 421 and the vertical spring slider 423 respectively, and can be compressed and stretched as the vertical relative position of the perforated spring end plate 421 and the vertical spring slider 423 changes.
[0065] The limiting rod 424 is connected to the vertical spring slider 423 and maintains the same displacement. The limiting rod 424 passes through the vertical spring 422 and is connected to the center hole of the perforated spring end plate 421. The limiting rod 424 can limit the out-of-plane deformation of the vibration reduction and noise reduction module 4.
[0066] The perforated spring end plate 421 is connected to the ring-shaped clamp 3 by bolts.
[0067] See Figure 8 The transverse spring module 43 includes a transverse spring slide rail 412, an arc-shaped spring end plate 431, a transverse spring 432, and a transverse spring slider 433.
[0068] The transverse spring slide rail 412 is located on one end face of the counterweight box 41 opposite to the cylindrical wall. The transverse spring slider 433 is assembled with the transverse spring slide rail 412 on the counterweight box 41 and is able to move along the direction of the transverse spring slide rail 412.
[0069] The transverse spring 432 is fixedly connected to the arc-shaped spring end plate 431 and the transverse spring slider 433 on both sides, and can be compressed and stretched as the horizontal relative position of the arc-shaped spring end plate 431 and the transverse spring slider 433 changes.
[0070] The arc-shaped spring end plate 431 is connected to the locking part reserved on the cylindrical wall with the annular plate clamp 3 through a locking device. The curvature of the side of the arc-shaped spring end plate 431 that is in contact with the annular plate clamp 3 is consistent with the outer surface of the cylindrical part with the annular plate clamp 3, while the other side remains flat. This ensures that the arc-shaped spring end plate 431 can be reliably and stably connected to the cylindrical wall with the annular plate clamp 3, thus ensuring the vibration reduction effect.
[0071] It should be noted that the horizontal spring slide rail 412 and the vertical spring slide rail 413 on the two adjacent surfaces need to be assembled with the horizontal spring slider 433 and the vertical spring slider 423 respectively. Additional lubrication or friction reduction measures are required to ensure that when the counterweight box 41 vibrates, the vertical spring slider 423 and the horizontal spring slider 433 can slide easily, so that the vertical spring 422 and the horizontal spring 432 can deform only in their own axial direction, ensuring that the vibration reduction effect is not affected by external factors.
[0072] The following example illustrates its working process in a specific application. However, it should be noted that the following content is only a specific application example of this solution and does not constitute a limitation on this solution.
[0073] First, the number of vibration reduction and noise reduction modules 4 and their distribution structure on the cylindrical wall of the clamp are determined according to the requirements of vibration reduction strength and directionality.
[0074] Then, insertable counterweights 44 are placed in the counterweight box 41 of the vibration reduction and noise reduction module. The number of insertable counterweights 44 in the counterweight box 41 in different directions is adjusted according to different scenarios and working conditions. The vibration reduction and noise reduction effect of the device of the present invention can be further precisely adjusted and controlled without the number of vibration reduction and noise reduction modules 4 being fixed, so as to adapt to different application scenarios.
[0075] After assembly, when the vertical pump pipe 1 vibrates horizontally, the vibration is transmitted to the vibration damping and noise reduction module 4 through the rubber layer 2 and the ring plate clamp 3, causing the counterweight box 41 to tend to move horizontally. At this time, the counterweight box 41 moves outward or inward along the axial direction of the transverse spring module 43, causing the transverse spring 432 to stretch or compress. Meanwhile, the vertical spring slider 423 in the vertical spring module 42 can move in the vertical spring slide rail 413 without deforming the vertical spring 422.
[0076] Conversely, when the vibration transmitted to the vibration reduction and noise reduction module 4 is vertical, only the vertical spring module 42 participates in the work, while the horizontal spring module 43 can slide and always maintain its original state without deformation.
[0077] When the vibration transmitted to the vibration damping and noise reduction module 4 is vertical, the vibration is transmitted to the vibration damping and noise reduction module 4 through the rubber layer 2 and the ring plate clamp 3, causing the counterweight box 41 to have a tendency to move vertically. At this time, the counterweight box 41 moves up and down along the vertical spring module 423, causing the vertical spring 422 to stretch or compress. Meanwhile, the horizontal spring slider 433 in the horizontal spring module 43 can move in the horizontal spring slide rail 412 without causing the horizontal spring 432 to deform.
[0078] Meanwhile, because the curve is located at the intersection of two directions, such as the intersection of two horizontal directions or the intersection of horizontal and vertical, the vibration at this point is particularly complex, exhibiting obvious three-dimensional six-degree-of-freedom vibration characteristics. At the same time, the internal concrete forms an impact effect here, resulting in a large vibration amplitude.
[0079] By installing this device at the connection between the bend and the straight pipe, the device can be distributed along the circumference of the pipe according to the stress conditions at the bend. At the same time, each device can reduce vibration in both axial and longitudinal dimensions. Therefore, the device at the bend can achieve a three-dimensional, six-degree-of-freedom vibration characteristic, which can effectively reduce the vibration and noise of the pump pipe, and at the same time reduce the risk of pipe blockage and bursting during the concrete pouring process.
[0080] The novel pump pipe vibration reduction and noise reduction device composed of the above scheme introduces a multi-level adjustable tuned mass damping mechanism through innovative structural design. It is suitable for different scenarios, buildings, floors and locations. Furthermore, as the construction progresses and the pumping height changes, the vibration reduction and noise reduction control parameters can be dynamically adjusted to achieve adaptive control "anytime and anywhere" and obtain the best vibration reduction and noise reduction effect.
[0081] Secondly, through a three-dimensional damping coupling design, three-dimensional six-degree-of-freedom vibration reduction of the concrete pump pipe is achieved, which can solve the problem of insignificant vibration reduction and noise reduction effects in sections where the pump pipe transitions between horizontal and vertical directions, as well as at bends. In addition, this device is attached to the pump pipe without needing to be connected to the main structure or support. It is small in size, easy to install and dismantle, does not affect the normal operation of the pump pipe, and does not hinder normal on-site construction operations.
[0082] Finally, this device adopts adaptive control technology, has a wide range of applications, and is modularly designed, enabling convenient recycling and reuse in the next project, saving engineering costs and helping to achieve the goal of green and low-carbon construction.
[0083] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
