Description

Technical Field

[0001] This invention relates to the field of dampers, and more particularly to a damper mounting and positioning device. Background Technology

[0002] A damper is a vibration reduction device used in building engineering. When a building vibrates, the damper reduces the amplitude of the sway by changing its length, thus ensuring the safety of the building.

[0003] The installation location for the damper needs to be reserved when the building is constructed. However, since the damper can only be installed after the building floor is topped out, the installation of the damper requires re-measurement and repositioning, which makes the installation of the damper quite troublesome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes a damper installation and positioning device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a damper installation and positioning device, comprising: an airbag four, a central pipe connected to the airbag four, and an airbag one connected to the central pipe; It also includes a box 2 disposed on the surface of airbag 1 and airbag 4. The inside of box 2 is equipped with an air pump for supplying air. Airbag 2 and airbag 3 are disposed on the surface of airbag 1 and airbag 4 respectively. Airbag 2 and airbag 3 are provided with a tube 1 inside. The inside of tube 1 is provided with a hole 2 inside. The inside of hole 2 is provided with a control device for first filling a section of airbag 2 or airbag 3 with the gas discharged by the air pump, and then the control device controls the gas to pass through to fill the next section of airbag 2 or airbag 3.

[0006] Preferably, the control device includes a central column, the surface of which is provided with a slidable elastic ring, one end of which is provided with an outer ring, and one end of the outer ring is provided with an elastic element for resetting.

[0007] Preferably, the surface of the central column is provided with a central plate. When gas enters the second or third airbag, the gas pushes the elastic ring to move on the surface of the central column, and the central plate pushes the elastic ring open to leave a channel for gas movement.

[0008] Preferably, the surface of the central column is provided with a side plate. When the gas leaves the second or third airbag, the gas generates negative pressure, which drives the elastic ring to move on the surface of the central column. The side plate pushes the elastic ring open, leaving a channel for the gas to move.

[0009] Preferably, the control device includes a frame, a ring on the surface of the frame, a movable ball on the surface of the ring, and an elastic rope connected to the ball inside the ring. When the ball is pushed by gas, the elastic rope is pulled.

[0010] Preferably, the interior of the second hole is provided with an expansion hole. When gas enters the second or third airbag, it pushes the first ball to move. The first ball moves to the expansion hole, and the space between the expansion hole and the first ball is used for gas movement.

[0011] Preferably, the interior of the second hole is provided with an expansion hole. When the gas leaves the second or third airbag, the negative pressure causes the first ball to move. The first ball moves to the expansion hole, and the space between the expansion hole and the first ball is used for gas movement.

[0012] Preferably, the surface of the second ring is provided with a groove for the ball to move.

[0013] Preferably, the inner part of the second box is provided with a ring, the inner part of the ring is provided with a plate, the surface of the plate is provided with a rotatable plate, the surface of the plate is provided with pipe four and pipe five respectively connected to the air pump outlet and air pump inlet, the surfaces of airbag one, airbag two, airbag three and airbag four are provided with a box for communication, the surface of the plate is provided with pipe seven and pipe six respectively connected to the box and the outside gas, when the plate is rotated, the connection relationship of pipe seven, pipe six, pipe four and pipe five is changed.

[0014] Preferably, the second box has a motor inside, and the surface of the motor has teeth that connect to the first plate.

[0015] Compared with existing technologies, the advantages of this invention include: maintaining the theoretical axis through a rigid central pipe, combined with the sequential inflation and adaptive deformation capabilities of the airbag assembly, automatically compensating for and conforming to irregular installation surfaces, effectively eliminating installation gaps and deviations, and ensuring precise alignment of the damper installation position; the self-sequential deployment of the airbags avoids the cumbersome manual pulling, adjustment, and temporary support steps of traditional methods; one-button inflation / pressure holding / expansion control greatly simplifies the operation process, reduces reliance on skilled workers, improves installation efficiency and consistency, and reduces human error; after inflation and pressure holding, the airbag assembly provides uniform and adjustable pressure across the entire contact surface, forming a gapless flexible clamp, providing extremely stable temporary fixation for subsequent welding or fastening operations, preventing displacement before final installation; both control device designs (elastic ring type and ball valve type) can reliably achieve sequential airflow control, ensuring orderly inflation and thorough expulsion. The integrated rotary valve control box achieves compactness of the core air circuit functions and precise mode switching; the device can adapt to various complex installation surface conditions, and the design of the airbags and control devices considers contamination resistance and reliability. The overall structure is easy to store, transport and reuse, and has low maintenance costs. Attached Figure Description

[0029] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Example 1 According to one embodiment of the present invention, Figures 1-5 As shown, the basic structure of the device of the present invention includes a rigid central pipe 3 serving as a load-bearing frame. The central pipe 3 is preferably made of aluminum alloy profile with a square or circular cross-section, possessing sufficient bending and torsional stiffness to simulate and maintain the theoretical mounting axis of the damper. The two ends of the central pipe 3 are connected to and fixed to airbag 1 and airbag 4 5 respectively via flanges or sealing joints. Airbag 1 and airbag 4 5, acting as the "end actuators" of the device, are made of high-strength, low-permeability rubber composite material, and are initially in a folded state.

[0032] Airbag 2 is fixed on the outer surface of airbag 1, and airbag 3 is fixed on the outer surface of airbag 4. The size of airbag 2 and airbag 3 is smaller than that of airbag 1 and airbag 4. Airbag 2 and airbag 3 are square. A rigid pipe 8 as an internal air passage is pre-embedded at the corner of airbag 2 and airbag 3.

[0033] The inflation and deflation ports of airbag 1, airbag 2, airbag 3, and airbag 4 are collected and managed through a centrally arranged box 6. The box 6 has precision-machined flow channels that distribute the total air source from the control box 7 to each airbag sequence, or collect and discharge the gas from each airbag.

[0034] The control box 7 integrates an air pump 10, a motor 17, and an air path switching valve for switching working modes.

[0035] To solve the sequential control problem, a special hole 19 is provided inside the tube 8 connecting the airbags in series. A control device is installed inside this hole. The core function of this control device is to achieve "sequential airflow." During inflation, gas from the air pump 10 first enters the first airbag, namely the first airbag 2 and airbag 4 closest to the central tube 3, and fills it. Only when the internal pressure of this airbag reaches a preset value does the control device activate, opening the passage to the next airbag. This process repeats until all airbags in the sequence are inflated sequentially. Simultaneously, because airbag 5 and airbag 1 have tube 9 inside, the gas flow space in airbag 5 and airbag 1 is smaller than that in airbag 4 and airbag 2. Airbag 34 quickly inflates airbag 1 and airbag 45. After airbag 2 and airbag 34 are fully inflated, the subsequent gas fills airbag 1 and airbag 45. Airbag 1, airbag 2, airbag 34 and airbag 45 support the surface of wall 35. Mounting seat 36 is installed in groove 2 38 on the surface of wall 35. Wall damper 37 is fixed on the surface of mounting seat 36, partially opening the wall 35 to ensure the installation of wall damper 37. During the exhaust process, the control device should also be able to open smoothly to allow the gas to be discharged quickly. This design allows the device to adapt point by point and gradually fill the gaps when contacting irregular or deviated mounting surfaces, eventually forming a uniform and stable support contact surface, thereby positioning the installation position of the damper.

[0036] Example 2 According to one embodiment of the present invention, Figures 1-8 As shown, This embodiment focuses on describing the specific structure of the first type of control device integrated within tube 8.

[0037] The core component of the control device is a central column 21 fixedly installed in the center of the flow channel of hole 2 19. The central column 21 has two protruding annular steps machined axially, namely the upper central plate 24 and the lower side plate 20. The diameter of the central column 21 is smaller than the outer diameter of the side plate 20 and the central plate 24.

[0038] The elastic ring 22 is fitted onto the shaft of the central column 21 and can slide along the shaft axis. A lightweight alloy outer ring 23 is tightly fitted around the outer periphery of the elastic ring 22. The elastic element 25 is installed on the upper end of the outer ring 23. The other end of the elastic element 25 is fixedly connected to the inner wall of the second hole 19. The preload of the elastic element 25 ensures that the sliding assembly composed of the elastic ring 22 and the outer ring 23 is located in the middle position of the central column 21 under the initial no air pressure or low pressure state.

[0039] Since the elastic ring 22 is in contact with the surface of the central column 21, and the elastic ring 22 is tilted downward relative to the outer ring 23, when gas enters the second bladder 2 and the third bladder 4, the elastic ring 22 is squeezed against the surface of the central column 21 due to the compression of the gas. The elastic ring 22 is more closely attached to the surface of the central column 21, preventing gas from passing through. This is the initial closed state of the device.

[0040] During the inflation process, the air pump 10 inflates the box 6. The gas inside the box 6 enters the airbags 1, 2, 4, and 5. Due to the obstruction of the tube 9, the gas preferentially enters the airbags 4 and 2. The gas pressure inside the airbags 4 and 2 is low and cannot overcome the pre-tightening force of the elastic element 25. Therefore, the gas cannot directly pass through the tube 8. The gas fills a section of the airbags 4 and 2 near the air pump 10. The high-pressure gas inside the airbags 4 and 2 deploys a portion of them, avoiding the trouble caused by manual pulling. As the air pump 10 continues to supply air, the pressure inside the airbags continues to rise. This is sufficient to push the outer ring 23 to squeeze the elastic element 25, causing the elastic ring 22 to move upward along the middle plate 24. The elastic ring 22 is then stretched open, creating a gap between the four elastic rings 22, allowing gas to pass through and flow to the next section of airbag 3 4 and airbag 2 2. By separating and stretching each section of airbag 3 4 and airbag 2 2, airbag 1 1, airbag 2 2, airbag 3 4 and airbag 4 5 can unfold on their own, avoiding the trouble caused by manually pulling the airbags. By precisely designing the stiffness coefficient and pre-compression amount of the elastic element 25, the pressure threshold for triggering the opening of the channel can be set. This threshold should ensure that the previous section of airbag 3 4 and airbag 2 2 is basically filled and forms an effective supporting force with the contact surface before the next stage of filling is started.

[0041] During the exhaust process, the air pump 10 extracts the gas from inside airbags 2 and 3. After a section of the gas inside airbags 2 and 3 is extracted, a negative pressure is generated inside airbags 2 and 3. The outer ring 23 moves downward, and the elastic ring 22 slides on the surface of the central column 21. The elastic ring 22 is squeezed by the test plate 20, and the four elastic rings 22 are separated, leaving a gas channel. The gas is then completely extracted, and airbags 1, 2, 3, and 5 can quickly contract. After the exhaust is completed, under the restoring force of the elastic element 25, the elastic ring 22 and the outer ring 23 return to the middle position of the central column 21, maintaining the sealing effect and preparing for the next use.

[0042] Example 3 According to one embodiment of the present invention, Figures 1-10 As shown in this embodiment, another alternative control device structure is illustrated, which can also achieve segmented control function, but adopts a different mechanical principle.

[0043] The control device includes a bracket 27 fixed inside hole 19 by a support. A ring 28 is fixed on the bracket 27. Two axial grooves 29 are symmetrically opened on the circumferential wall of the ring 28. A ball 30 is provided inside hole 19. The ball 30 fits into the inside of hole 19 to achieve a sealing effect. The ball 30 can slide axially in the groove 29. An elastic rope 32 is provided inside ring 28. The elastic rope 32 is connected to the ball 30. The ball 30 is fixedly connected to the elastic rope 32 by an elastic material plate. The elastic material plate can fit the shape of ring 28 when the ball 30 moves. The natural length of the elastic rope 32 makes the ball 30 approximately located in the middle area of ​​the groove 29 when there is no external force. The ball 30 is made of elastic material. The ball 30 slightly deforms and fits into the inside of hole 19 to seal the gas.

[0044] Inside the flow channel of Hole 2 19, on both sides of Ball 1 30, there are Hole 1 26 and Hole 2 31 respectively. The diameters of Hole 1 26 and Hole 2 31 are significantly larger than the diameter of Ball 1 30.

[0045] During inflation, as gas enters from the bottom, the gas pressure acts directly on sphere 30. When the airflow force exceeds the tension of the elastic rope 32 on sphere 30, sphere 30 is pushed and moves to the right along groove 29. Sphere 30 is pushed to the far right and enters the expansion hole 26 area. Since the diameter of expansion hole 26 is much larger than the diameter of sphere 30, after sphere 30 moves to this position, a huge annular gap is formed between it and the hole wall, allowing airflow to pass unimpeded. As long as the inflation pressure is maintained, sphere 30 is held at expansion hole 26, and elastic rope 32 is stretched. This design ensures that in the initial inflation stage, airflow is mainly directed to the first airbag. Only after its pressure builds up to a certain value is the sphere moved, opening the main channel to supply the next airbag.

[0046] During the exhaust process, when the system exhausts, the air pump 10 draws out the gas inside the airbag, and the airflow direction changes from right to left. The negative pressure suction generated by the airflow acts on the ball 30, pulling it down along the groove 29. The ball 30 is pulled to the bottom and enters the expansion hole 31 area. The huge annular gap formed here provides a fast channel for the reverse airflow. After the exhaust is completed, under the action of the elastic rope 32, the ball 30 is pulled back to the initial position in the middle of the loop 28.

[0047] This triggering mechanism, based on fluid dynamics and elastic constraints, also achieves sequential control, and has relatively low requirements for gas cleanliness, making the structure more resistant to contamination.

[0048] Example 4, according to an embodiment of the present invention, combined with Figures 1-10 As shown, this embodiment details the central gas path control scheme applicable to all the above embodiments. This scheme is integrated in the control box 7 and is responsible for the switching of the entire device's inflation, pressure holding, and deflation modes.

[0049] The core of the control box 7 is a rotary valve-type air circuit switching mechanism, which includes a plate 15 fixedly installed inside ring 13. Two holes 18 are precisely machined on plate 15, which are aligned with holes 18 on the surface of the rotatable plate 14.

[0050] Above plate 2 15, plate 1 14 is tightly fitted and rotatably mounted. Plate 1 14 is driven to rotate by micro motor 17 through gear 16. Two holes 18 are also machined on plate 1 14.

[0051] By controlling motor 17 to rotate plate 14 to a specific angle, the correspondence between the two holes on plate 14 and the two holes on plate 15 can be changed, thereby achieving at least three basic working modes: Inflation mode: When hole 18 on plate 2 15 is aligned with hole 18 on the surface of plate 1 14, pipe 4 11 is connected to pipe 7 34, and pipe 5 12 is connected to pipe 6 33, the air pump 10 draws gas from pipe 6 33 and introduces it into pipe 7 34.

[0052] Pressure holding mode: Control the motor to rotate plate 14 to another angle, so that hole 18 on it is misaligned with hole 18 on plate 2 15, that is, pipe 7 34 is closed. At this time, the airbag assembly is isolated from the air pump and the atmosphere, and the system maintains pressure to achieve temporary fixation.

[0053] Exhaust mode: Control motor 17 to rotate plate 14, hole 18 of plate 2 15 is misaligned with hole 18 on the surface of plate 14, pipe 4 11 is connected to pipe 6 33, and pipe 5 12 is connected to pipe 7 34. Then the air pump 10 draws gas from pipe 7 34 and introduces it into pipe 6 33.

[0054] The entire device is placed within the predetermined installation space of the damper. Its rigid central pipe 3 is used to simulate and maintain the theoretical installation axis. The two sides of the device are composed of folded airbag groups (airbag 1, airbag 2, airbag 3, and airbag 4).

[0055] Start the air pump 10 to enter the inflation mode. The internal air pump 10 starts working, and the air circuit switching valve connects the system to the inflation circuit.

[0056] Gas priority distribution and first stage filling: After the high-pressure gas is distributed by box 16, due to the obstruction of tube 39 inside airbag 1 and airbag 45, the gas preferentially enters the first stage of airbag 2 and airbag 34 that is closest to the gas source. At this stage, the gas pressure is low and cannot trigger the control device connected in series in tube 18, the elastic ring assembly or ball valve assembly in hole 219, and the airflow is temporarily blocked.

[0057] Gas accumulates in the first closed section, and the pressure continues to rise, causing the corresponding airbag section, part of airbag 2 or airbag 3 to open up and initially contact the mounting surface.

[0058] When the internal pressure of the first airbag reaches the preset threshold, the control device is triggered (the elastic ring assembly moves upward to open the annular gap, or the ball valve moves to the expansion area), opening the channel to the next airbag. The airflow enters and fills the subsequent airbags 2 and 4 in sequence. This process is carried out segment by segment to ensure that the airbags unfold sequentially and stably from the middle, gradually adapting to and filling the irregular gaps on the mounting surface.

[0059] The end air bladders are finally filled: After all sections of air bladder 2 and air bladder 3 are filled, the subsequent gas begins to overcome the obstruction of tube 39 and rush into air bladder 1 and air bladder 4 at both ends, completely filling and compacting them, and finally forming a uniform, stable and highly fitted support contact surface between the entire device and the mounting surface, accurately completing the centering and positioning of the damper.

[0060] By switching to the pressure-holding mode via control box 7, the air circuit switching valve cuts off the connection between the airbag assembly and the air pump and the outside world, so that the entire system maintains a constant pressure. The device is firmly locked in the installation position by the pressure inside the airbag, providing a stable temporary fixation for the subsequent formal installation of the damper.

[0061] After the damper is installed, the control box 7 switches to the exhaust mode, the air pump 10 works, and draws air from the airbag assembly. At this time, the control device opens smoothly under the action of reverse airflow or negative pressure (such as the elastic ring assembly moving down or the ball valve moving to another expansion area), ensuring that the gas in all sections can be quickly and completely extracted. Each airbag then quickly contracts and returns to its folded state. The entire device can be easily removed from the installed damper for easy reuse.

[0062] By maintaining the theoretical axis through a rigid central conduit, combined with the sequential inflation and adaptive deformation capabilities of the airbag assembly, the device can automatically compensate for and conform to irregular installation surfaces, effectively eliminating installation gaps and deviations, and ensuring precise alignment of the damper installation position. The self-deploying sequential deployment of the airbags avoids the cumbersome manual pulling, adjustment, and temporary support steps of traditional methods. One-button inflation / pressure holding / expansion control greatly simplifies the operation process, reduces reliance on skilled workers, improves installation efficiency and consistency, and reduces human error. After inflation and pressure holding, the airbag assembly provides uniform and adjustable pressure across the entire contact surface, forming a gapless flexible clamp, providing extremely stable temporary fixation for subsequent welding or fastening operations, and preventing displacement before final installation. Both control device designs (elastic ring type and ball valve type) can reliably achieve sequential airflow control, ensuring orderly inflation and thorough expulsion. The integrated rotary valve control box achieves compactness of core air circuit functions and precise mode switching. The device can adapt to various complex installation surface conditions, and the design of the airbags and control devices takes into account contamination resistance and reliability. The overall structure is easy to store, transport and reuse, and has low maintenance costs.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
