Description

Technical Field

[0001] This invention relates to the field of building construction technology, and mainly to a self-sensing three-dimensional vibration isolation support suitable for wall panel transport brackets. Background Technology

[0002] With the promotion of industrialized construction, the application scope of prefabricated assembly structure systems is becoming increasingly wider. However, compared with traditional cast-in-place shear walls, prefabricated assembly structures require long-distance and multi-condition transportation. In particular, for prefabricated components with integrated interior and exterior wall decoration layers, higher requirements are placed on the protection of finished products and energy dissipation and vibration reduction during transportation.

[0003] However, existing vibration isolation supports for component transport frames lack vibration isolation design tailored to the characteristics of the transport frame tonnage and road conditions, and cannot meet three-dimensional vibration isolation requirements. When transport acceleration has a significant impact on the components, they cannot provide real-time early warning information to the driver, which can lead to damage to the components during transport.

[0004] Therefore, it is necessary to provide three-dimensional vibration isolation supports suitable for transport frames to reduce vibration during component transportation, while monitoring transportation acceleration in real time and reminding drivers to drive smoothly, thereby protecting the components during transportation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a self-sensing three-dimensional vibration isolation support suitable for wall panel transport brackets. This support weakens the three-dimensional vibration of the components through a friction pendulum module and a vertical vibration isolation module, and provides real-time feedback warning information to the driver through a self-sensing module.

[0006] To achieve the above objectives, the present invention provides a self-sensing three-dimensional vibration isolation support suitable for wall panel transport brackets. This support connects to the transport bracket and includes a friction pendulum module, a vertical vibration isolation module, and a self-sensing module. The top of the friction pendulum module is connected to the vertical vibration isolation module, thereby reducing the horizontal vibration of the transport bracket.

[0007] The vertical vibration isolation module reduces the vertical vibration of the transport support.

[0008] The self-sensing module is connected to the vertical vibration isolation module, monitors the acceleration of the transport support in real time, and transmits the acceleration signal to the signal receiving module.

[0009] Furthermore, the friction pendulum module includes a friction pendulum support base plate, a spherical cap, and a first surface of an intermediate connecting component, wherein the spherical cap is disposed between the friction pendulum support base plate and the intermediate connecting component.

[0010] Furthermore, the first surface of the intermediate connecting component is provided with a first concave spherical surface in the middle, and a first annular baffle is provided around the first concave spherical surface. The upper surface of the friction pendulum support base plate is provided with a second concave spherical surface in the middle, and a second annular baffle is provided around the second concave spherical surface.

[0011] Furthermore, the radius of the first annular baffle is smaller than the radius of the second annular baffle, and the net difference between the radii of the first annular baffle and the second annular baffle is the allowable horizontal displacement of the transport support.

[0012] Furthermore, the spherical cap is a flattened cylinder with convex spherical surfaces on both the upper and lower surfaces. The spherical curvature of the convex spherical surface is the same as that of the first concave spherical surface and the second convex spherical surface.

[0013] Furthermore, the vertical vibration isolation module includes a second surface of an intermediate connecting component, a vertical rubber pad, and an upper cover connecting component, wherein the vertical rubber pad is disposed between the second surface of the intermediate connecting component and the upper cover connecting component.

[0014] Furthermore, the second surface of the intermediate connecting assembly and the upper cover connecting assembly are connected by a guide screw and a limiting nut.

[0015] Furthermore, the second surface of the intermediate connecting component is provided with a first square enclosure, and the lower surface of the upper cover connecting component is provided with a second square enclosure. The outer diameter of the second square enclosure is smaller than the inner diameter of the first square enclosure. In the working state, the second square enclosure will enter the first square enclosure and restrict the relative horizontal displacement of the intermediate connecting component and the upper cover connecting component.

[0016] Furthermore, the vertical rubber pad is in the form of a square column, the outer diameter of which is smaller than the inner diameter of the second square enclosure, and the difference satisfies the lateral expansion distance of the vertical rubber pad.

[0017] Furthermore, the self-sensing sensor includes a three-dimensional accelerometer, a signal processing module, a signal transmitting module, and a signal receiving module installed in the driver's cab.

[0018] This invention provides a self-sensing three-dimensional vibration isolation support for wall panel transport brackets. It employs a friction pendulum module to weaken the horizontal vibration of the transport bracket and a vertical vibration isolation module to weaken its vertical vibration. A baffle on the friction pendulum module prevents excessive horizontal displacement of the support. A baffle on the vertical vibration isolation module ensures that the intermediate connecting assembly and the upper cover connecting assembly connected to the vertical support maintain relative vertical displacement and constrain relative horizontal displacement during operation. Limit nuts and guide screws limit excessive vertical displacement of the support, ensuring that the second square baffle in the vertical vibration isolation module does not detach from the first square enclosure during operation, thus guaranteeing the stability and safety of the support. Simultaneously, a self-sensing module monitors the acceleration at the bottom of the transport bracket in real time. When the acceleration exceeds a design threshold, it alerts the driver to reduce acceleration or braking intensity and drive smoothly. This effectively reduces the vibration of the transport bracket and ensures safe transport. Attached Figure Description

[0035] 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.

[0036] The self-sensing three-dimensional vibration isolation support for wall panel transport brackets provided by this invention uses a friction pendulum module to weaken the horizontal vibration of the transport bracket and a vertical vibration isolation module to weaken the vertical vibration of the transport bracket. Furthermore, baffles installed on the friction pendulum module and the vertical vibration isolation module limit excessive horizontal displacement of the support, while limit nuts and guide screws limit excessive vertical displacement of the support, ensuring the stability and safety of the support. Simultaneously, a self-sensing module monitors the acceleration at the bottom of the transport bracket in real time, and when it exceeds the design threshold, it reminds the driver to reduce acceleration or braking intensity and drive smoothly.

[0037] See Figures 1 to 3 The image shows an example of a self-sensing three-dimensional vibration isolation support for wall panel transport brackets provided by the present invention.

[0038] As shown in the figure, the self-sensing three-dimensional vibration isolation applicable to the wall panel transport support in this example mainly includes a friction pendulum module 100, a vertical vibration isolation module 200, and a self-sensing module 300.

[0039] The friction pendulum module 100 is connected to the vertical vibration isolation module 200 at the top, and the self-sensing module 300 is located at the bottom of the vertical vibration isolation module 200.

[0040] See Figures 4 to 6 The friction pendulum module 100 is mainly composed of the first surface 112 of the intermediate connecting component 110, the spherical cap 120, and the friction pendulum support base plate 130.

[0041] The intermediate connecting component 110 and the friction pendulum support base plate 120 are preferably square in the same size to ensure the stability of the friction pendulum module 110. The spherical cap 120 is disposed between the intermediate connecting component 110 and the friction pendulum support base plate 130.

[0042] Among them, bolt holes 111 are provided on the four corners of the intermediate connecting component 110 and the friction pendulum support base plate 130, and a first concave spherical surface 113 is provided in the middle of the first surface 112 of the intermediate connecting component 110, and a first annular baffle 114 is provided around the circumference of the first concave spherical surface 113.

[0043] The upper surface of the friction pendulum support base plate 130 is provided with an inwardly recessed second concave spherical surface 131, and a second annular baffle 132 is provided around the circumference of the second concave spherical surface 131.

[0044] The radius of the first annular baffle 114 is smaller than the radius of the second annular baffle 132. Correspondingly, the radius of the first concave spherical surface 113 is smaller than the radius of the second concave spherical surface 131. Considering the thickness of the first annular baffle 114 and the second annular baffle 132, the net difference in their radii is the magnitude of the horizontal displacement that the transport support is allowed to send.

[0045] Thus, the first annular baffle 114 on the first surface 112 of the intermediate connecting assembly 110 can be placed inside the second annular baffle 132 on the friction pendulum support base plate 130, forming a first receiving cavity. The first annular baffle 114 and the second annular baffle 132 restrict the relative horizontal displacement between the intermediate connecting assembly 110 and the friction pendulum support base plate 130.

[0046] The outer side and lower surface of the first annular baffle 114, as well as the inner side and upper surface of the second annular baffle 132, are provided with a first buffer layer 134. The first buffer layer 134 is preferably made of a rubber pad to buffer the relative horizontal displacement of the intermediate connecting assembly 110 and the friction pendulum support base plate 130.

[0047] The spherical cap 120 is a flattened cylinder with convex spherical surfaces 121 protruding outward on both the upper and lower surfaces. The spherical curvatures of the convex spherical surface 121, the first concave spherical surface 113, and the second concave spherical surface 131 are the same, so that the upper and lower surfaces of the spherical cap 120 can be adapted to the first concave spherical surface 113 and the second concave spherical surface 131.

[0048] Thus, the spherical crown 120 can be placed in the first receiving cavity formed by the first concave spherical surface 113 and the first annular baffle 114 on the first surface 112 of the intermediate connecting component 110, and the second concave spherical surface 131 and the second annular baffle 132 on the upper surface of the friction pendulum support base plate 130; at the same time, the first annular baffle 114 on the first surface 112 of the intermediate connecting component 110 is placed inside the second annular baffle 132 on the friction pendulum support base plate 130.

[0049] Here, the height of the spherical crown 120, the first annular baffle 114 and the second annular baffle 132 are not limited. It is necessary to ensure that the spherical crown 120 can be completely placed in the first receiving cavity, and that the contact portion between the second annular baffle 132 and the first annular baffle 114 on the friction pendulum support base plate 130 is sufficient to transmit horizontal shear force.

[0050] The friction pendulum module 100 is connected to the vertical vibration isolation module 200 at the top.

[0051] See Figures 7 to 9 The vertical vibration isolation module 200 is mainly composed of the second surface 115 of the intermediate connecting component 110, the vertical rubber pad 210, and the upper cover connecting component 220.

[0052] The top cover connecting component 220 is preferably set as a square with the same size as the middle connecting component 110 to ensure the stability of the vertical vibration isolation module 200. The vertical rubber pad 210 is set between the middle connecting component 110 and the top cover connecting component 220.

[0053] Among them, bolt holes 111 are provided at the four corners of the upper cover connecting component 220 corresponding to the middle connecting component 110, and corresponding guide screw holes 116 are provided in the middle of the four sides of the upper cover connecting component 220 and the middle connecting component 110.

[0054] The second surface 115 of the intermediate connecting component 110 is provided with a first square fence 117 in the middle, and the lower surface of the upper cover connecting component 220 is provided with a second square fence 221. The outer diameter of the second square fence 221 is smaller than the inner diameter of the first square fence 117, and the difference between the two is about 2mm.

[0055] Thus, the second square fence 221 on the lower surface of the upper cover connecting assembly 220 can be placed inside the first square fence 117 on the second surface 115 of the intermediate connecting assembly 110, forming a second receiving cavity. The first square fence 117 and the second square fence 221 restrict the relative horizontal displacement of the upper cover connecting assembly 220 and the intermediate connecting assembly 110.

[0056] The upper surface of the first square fence 117 and the lower surface of the second square fence 221 are both provided with a second buffer layer 223. The second buffer layer 223 is preferably a thin buffer rubber pad to buffer the relative vertical displacement of the upper cover connecting component 220 and the middle connecting component 110.

[0057] The vertical rubber pad 210 is preferably in the form of a square column, with its outer diameter being smaller than the inner diameter of the second square enclosure 221. The difference between the two satisfies the lateral expansion distance of the vertical rubber pad 210 under working conditions.

[0058] Thus, the vertical rubber pad 210 can be placed in the second receiving cavity formed by the second square enclosure 221 on the upper cover connecting assembly 220 and the first square enclosure 117 on the second surface 115 of the intermediate connecting assembly 110, and the center of the first square enclosure 117 and the center of the second square enclosure 221 are fixedly connected by bolts 211 located in the center of the vertical rubber pad 210.

[0059] In the working state, the second square enclosure 221 on the lower surface of the upper cover connecting assembly 220 should extend into the first square enclosure 117 on the second surface 115 of the intermediate connecting assembly 110, and ensure that the second square enclosure 221 does not leave the range of the first square enclosure 117 on the second surface 115 of the intermediate connecting assembly 110 when it vibrates up and down.

[0060] The vertical vibration isolation module 200 also includes a guide screw 230.

[0061] The guide screw 230 passes through the guide screw hole 116 provided on the intermediate connecting assembly 100 and the upper cover connecting assembly 220. Its bottom end passes through the intermediate connecting assembly 100 and is tightened by a nut. Its top end passes through the upper cover connecting assembly 220 and a limiting device 231 is set at a certain height.

[0062] Here, the limiting device 231 is preferably composed of a limiting nut, which facilitates connection with the wire screw 230. The setting height of the limiting device 231 is not limited, but it must be ensured that in the working state, the second square enclosure 221 on the lower surface of the upper cover connecting assembly 220 does not detach from the first square enclosure 117 on the second surface 115 of the intermediate connecting assembly 110.

[0063] The top cover connecting assembly 220 of the vertical vibration isolation module 200 is connected to the bottom of the self-sensing module 300.

[0064] See Figure 10 The self-sensing module 300 includes a self-sensing sensor 310 and a signal receiving module 320 installed in the cab.

[0065] The self-sensing sensor 310 includes a triaxial acceleration sensor 311, a signal processing module 312, and a signal transmission module 313.

[0066] The signal receiving module 320 includes a signal receiver 321 and a signal display module 322.

[0067] The three-dimensional acceleration sensor 311 monitors the acceleration at the bottom of the transport support in real time. When the acceleration exceeds the design threshold, the signal processing module 312 processes the acceleration data and transmits the acceleration signal to the signal receiver 321 in the cab. The signal display module 322 then generates a warning signal to remind the driver to reduce acceleration or braking intensity and drive smoothly.

[0068] The intermediate connecting component 110 and the friction pendulum support base plate 120, and the upper cover connecting component 220 are all square in size, and bolt holes 111 are provided at corresponding positions. When installing the vibration isolation support provided by the present invention, the intermediate connecting component 110 and the friction pendulum support base plate 120 are connected by the installation bolts passing through the bolt holes 111 to prevent the friction pendulum module 100 from sliding. The intermediate connecting component 100 and the upper cover connecting component 220 are connected by the guide screw 230 to prevent the upper cover connecting component 220 from falling off.

[0069] When installing the self-sensing three-dimensional vibration isolation bracket for wall panel transport bracket provided by the present invention with the wall panel transport bracket, first connect the friction pendulum support base plate 130 to the vehicle body by mounting bolts.

[0070] Hoist the wall panel transport bracket to the support, and then connect the upper cover connecting assembly 220 to the bottom of the transport bracket using installation bolts, ensuring that the guide screw 230 passes through the pre-reserved guide hole at the bottom of the bracket.

[0071] Slowly lower the frame until the vertical rubber pad 210 reaches the compression balance position, ensuring that the second square enclosure 221 on the lower surface of the upper cover connecting assembly 220 extends into the first square enclosure 117 on the second surface 115 of the intermediate connecting assembly 110.

[0072] At the same time, ensure that the first annular baffle 114 of the first surface 112 of the intermediate connecting component 110 is placed inside the second annular baffle 132 on the upper surface of the friction pendulum support base plate 130.

[0073] Finally, a limiting device 231 is installed on the guide screw 230 at the designed height position, such as... Figure 1 .

[0074] The following examples illustrate the working process of this invention in a specific application. It should be noted that the content described here is only a specific application example of this solution and does not constitute a limitation on this solution.

[0075] For horizontal vibrations (especially large impact loads generated during acceleration and deceleration), the friction pendulum module 100's friction pendulum support base plate 130 exhibits relative horizontal slippage within the allowable displacement range. This can filter high-frequency impact loads, reduce load amplitude, and significantly reduce the horizontal vibration transmitted to the frame. Furthermore, the friction generated by the convex spherical surface 121 of the friction pendulum spherical crown 120, the second concave spherical surface 131 on the upper surface of the friction pendulum support base plate 130, and the first concave spherical surface 113 of the intermediate connecting component 110 dissipates vibration energy. When the relative horizontal displacement equals the allowable displacement, the first annular baffle 114 contacts the second annular baffle 132, ensuring that the relative displacement between the intermediate connecting component 110 and the upper frame and the friction pendulum support base plate 130 does not exceed the allowable value, and ensuring reliable force transmission.

[0076] For vertical vibration (mainly vertical vibration loads caused by uneven ground), after the upper frame and walls are installed, the vertical rubber pad 210 is compressed under force, and the second square enclosure 221 on the lower surface of the upper cover connecting component 220 enters the first square enclosure 117 on the second surface 115 of the intermediate connecting component 110 and is stabilized at the preset equilibrium height. When vertical vibration occurs, the upper cover connecting component 220 and the intermediate connecting component 110 generate relative vertical displacement. Since the vertical rubber pad 210 has low stiffness, it can filter high-frequency vertical vibration and significantly reduce the vertical vibration transmitted to the frame. The second square enclosure 221, the first square enclosure 117, and the guide screw 230 together ensure that the upper cover connecting component 220 and the intermediate connecting component 110 do not generate relative horizontal displacement. The guide screw 230 and the limiting device 231 ensure that the second square enclosure 221 does not leave the range of the first square enclosure 117, ensuring the effective operation of the system.

[0077] Before transportation, the maximum acceleration that the prefabricated components can withstand is determined through stress analysis and used as the system acceleration threshold. This threshold is then calibrated in the self-sensing module 300. When the acceleration value of the cover connection component 220 detected by the self-sensing module 300 reaches this threshold, the acceleration is transmitted to the signal receiving module, thereby generating a warning signal to remind the driver to reduce acceleration or braking intensity and drive smoothly.

[0078] 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.
