Description

Technical Field

[0001] The utility model relates to the technical field of structural engineering, and particularly relates to a tensile force measuring and height adjusting support. Background Art

[0002] In bridge or building structures, in order to adapt to horizontal displacements, rotations, and seismic isolation requirements caused by climate effects (such as temperature changes, air pressure fluctuations, etc.) and uneven forces, it is necessary to install supports to reliably transfer the reaction forces of the upper structure to the lower structure, thereby reducing and eliminating the influence of the deformation of the upper structure on the lower structure. Generally, it is required that the supports have the ability to bear vertical loads, have rotational performance and horizontal displacement performance. In most cases, conventional spherical bearings already have the above functions and can meet the needs of engineering design. However, in some cases, especially in coastal areas, the rock formation structure is relatively weak and the wind influence is frequent, tensile forces may occur at individual supports or the structural foundation may sink. At this time, there are requirements for the force measuring performance and height adjusting performance of the supports. Currently, supports with force measuring and height adjusting functions are prone to the risk of beam dropping during service due to the lack of anti-pulling function, which greatly reduces the safety of the supports and results in the lack of guarantee for the safety of the bridge structure. In this context, a simple, convenient and reliable anti-pulling support with force measuring and height adjusting functions is very important. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a tensile force measuring and height adjusting support, which has good anti-pulling force, greatly reduces the risk of beam dropping, improves the safety of the support, and also guarantees the safety of the structure.

[0024] Embodiment

[0025] A tensile force measuring and height adjusting support includes a support body disposed between an upper structural member 1 and a lower structural member 2. The support body includes a first base 3 having a first pelvic cavity 7 and a second base 4 having a second pelvic cavity 9. The first base 3 is connected to the lower structural member 2, the second base 4 is slidably disposed in the first pelvic cavity 7, a rotating body is slidably disposed in the second pelvic cavity 9, a force measuring and height adjusting mechanism is disposed above the rotating body, the force measuring and height adjusting mechanism is connected to the upper structural member 1, a first tensile assembly for restricting the vertical displacement of the second base 4 is disposed on the top surface of the first base 3, and a second tensile assembly for restricting the vertical displacement of the rotating seat is disposed on the top surface of the second base 4.

[0026] In this embodiment, as Figure 1and Figure 2 As shown, the upper structure 1 and the lower structure 2 are the main parts to be connected and supported by the support. The upper structure 1 is a beam body, and the lower structure 2 is a beam or a pier. The support body mainly includes a first base 3 and a second base 4. The first base 3 has a first basin 7, which is connected to the lower structure 2 to provide basic support. The second base 4 is slidably arranged in the first basin 7 and can be laterally displaced as needed. The rotating body is located in the second basin 9 of the second base 4 and can slide therein. The design of the rotating body allows it to be rotated or tilted when necessary to adapt to different force conditions. The force measuring and height adjusting mechanism is arranged above the rotating body and connected to the upper structure 1. The force measuring and height adjusting mechanism can not only provide a connection between the structural members, The force measuring and height adjusting mechanism can measure the force it is borne in real time, and adjust the height of the upper structure 1 as needed to adapt to different usage scenarios and stress conditions. The first tensile component is arranged on the top surface of the first base 3, and its function is to limit the vertical displacement of the second base 4 to ensure that it does not move excessively or detach when subjected to tension. The second tensile component is arranged on the top surface of the second base 4 to limit the vertical displacement of the rotating body to ensure that it can remain stable when subjected to force. The first tensile component and the second tensile component make the bearing have a strong tensile resistance and can withstand external tension, ensuring the stability of the structural parts. In bridge engineering, the risk of falling beams is greatly reduced, the safety of the bearings is improved, and the safety of the bridge structure is also guaranteed.

[0027] Furthermore, the first tensile assembly includes a first fixed plate 5 and a first tensile plate 6. The first fixed plate 5 is arranged on the top surface of the first base 3 and is located outside the second base 4. The first fixed plate 5 and the top surface of the first base 3 constitute a first pelvic cavity 7. The first tensile plate 6 is arranged on the top surface of the first fixed plate 5. The first tensile plate 6 and the first fixed plate 5 form an L shape. The first tensile plate 6 is located above the second base 4. One end of the first tensile plate 6 is located above the end of the second base 4 and overlaps but does not contact.

[0028] Specifically, Figure 1 and Figure 2As shown in the figure, the first fixing plate 5 is arranged on the top surface of the first base 3 and is located outside the second base 4. The first fixing plate 5 and the top surface of the first base 3 together form the first pelvic cavity 7, which provides space for the sliding of the second base 4. The first tensile plate 6 is arranged on the top surface of the first fixing plate 5 and forms an L-shaped structure with the first fixing plate 5. The first tensile plate 6 is located above the second base 4, and its function is to limit the displacement of the second base 4 in the vertical direction. One end of the first tensile plate 6 is located above the end of the second base 4 and overlaps with the second base 4 but does not touch it, ensuring that when the second base 4 moves in the vertical direction, the first tensile plate 6 can provide the necessary support and limitation, while avoiding direct friction and contact between the two, thus extending the service life. Through its L-shaped structure and the overlapping design with the second base 4, the first tensile component provides strong tensile support for the second base 4. This design ensures that when the support is subjected to an external tensile force, the second base 4 can remain stable and will not move excessively or break away due to the tensile force. The first tensile plate 6 is located above the second base 4, and through its overlapping but non-contact design, it provides a limit for the vertical displacement of the second base 4. This design makes the second base 4 more stable during movement and reduces the sway caused by vibration or external forces. Since the first tensile plate 6 overlaps with the second base 4 but does not touch it, direct friction and contact between the two are avoided, which reduces the wear caused by friction and thus extends the service life of the support. In summary, through its unique design and function, the first tensile component of this tensile type force measuring and height adjusting support provides strong tensile support and stability for the entire support, ensuring the safety and reliability of the support under various stress conditions and avoiding the risk of beam dropping.

[0029] Furthermore, the first fixing plate 5 and the first base 3 are integrally formed or welded, and the first tensile plate 6, the first fixing plate 5, the first base 3, and the lower structural member 2 are bolted together.

[0030] Specifically, as Figure 1 and Figure 2As shown, the first fixing plate 5 and the first base 3 can be integrally formed, that is, the two are directly processed as a whole during the manufacturing process, ensuring the integrity and strength of the structure. Another connection method is welding. By using welding technology, the first fixing plate 5 and the first base 3 are firmly connected together, which can also achieve high structural strength and stability. The first tensile plate 6, the first fixing plate 5, the first base 3 and the lower structural member 2 are assembled by bolt connection. Bolt connection has the advantages of being detachable, reusable, and easy to install. Moreover, the pre-tightening force of the bolts can be adjusted as needed to ensure the tightness and stability of the connection. The integrally formed or welded connection method can ensure the firm and reliable connection between the first fixing plate 5 and the first base 3, reducing potential safety hazards caused by loose connection. The bolt connection method makes the entire support more convenient and flexible during the assembly and disassembly process, and can be adjusted and maintained as needed. Bolt connection can also withstand large tensile and shear forces, ensuring the stability and safety of the support when bearing external forces. Through the first tensile plate 6, the displacement of the second base 4 in the vertical direction can be effectively restricted, improving the tensile performance of the support. The bolt connection method enables the height of the entire support to be adjusted as needed to adapt to different usage scenarios and force conditions. In summary, this tensile force measuring and height adjustable support ensures its stability and safety during use through reasonable connection methods and structural designs, and has the characteristics of being convenient, flexible, and adjustable.

[0031] Furthermore, the distance between the bottom surface of the first tensile plate 6 and the top surface of the first base 3 is adapted to the thickness of the second base 4.

[0032] Specifically, as Figure 1 shown, the distance between the bottom surface of the first tensile plate 6 and the top surface of the first base 3 directly affects the stability and smoothness of the second base 4 during the sliding process. The distance needs to be adapted to the thickness of the second base 4. This means that when the second base 4 slides in the first pelvic cavity 7, its thickness should be slightly less than or equal to the distance between the bottom surface of the first tensile plate 6 and the top surface of the first base 3. This adaptability ensures that the second base 4 will not directly collide with or rub against the first tensile plate 6 during the sliding process, thereby reducing wear and noise and increasing the service life of the support.

[0033] Furthermore, the second tensile component includes a second fixing plate 8 and a second tensile plate 11. The second fixing plate 8 is fixed to the top surface of the second base 4 outside the rotating body. A second pelvic cavity 9 is formed between the second fixing plate 8 and the second base 4. The second tensile plate 11 is arranged on the top surface of the second fixing plate 8. The second tensile plate 11 and the second fixing plate 8 form an L shape. An assembly groove adapted to the second tensile plate 11 is provided on the side surface of the rotating body. The second tensile plate 11 extends into the assembly groove 14 to restrict the vertical displacement of the rotating body.

[0034] Specifically, as Figure 1 and Figure 2 shown, the second fixing plate 8 is fixed on the top surface of the second base 4, located outside the rotating body. A second pelvic cavity 9 is formed between the second fixing plate 8 and the second base 4, providing space for the sliding of the rotating body. The second tensile plate 11 is arranged on the top surface of the second fixing plate 8 and forms an L-shaped structure with the second fixing plate 8. This L-shaped design enables the second tensile plate 11 to effectively limit the displacement of the rotating body in the vertical direction. An assembly groove 14 adapted to the second tensile plate 11 is provided on the side surface of the rotating body. The second tensile plate 11 extends into this assembly groove 14, thereby restricting the movement of the rotating body in the vertical direction. By the second tensile plate 11 extending into the assembly groove 14 of the rotating body, the second tensile assembly can effectively limit the displacement of the rotating body in the vertical direction, which ensures that the rotating body will not move excessively when subjected to external forces, thus guaranteeing the stability of the entire bearing. The combination of the L-shaped second tensile plate 11 and the second fixing plate 8 makes the entire second tensile assembly have higher structural stability. This design can resist external forces from all directions and ensure that the bearing remains stable under various working conditions. The adaptation design of the second tensile plate 11 and the assembly groove 14 on the rotating body makes the assembly process of the entire assembly simple and fast. This design improves the installation efficiency of the bearing and reduces the installation cost. In summary, the second tensile assembly of this tensile type force-measuring and height-adjustable bearing effectively limits the displacement of the rotating body in the vertical direction through its unique design and function, ensuring the stability and safety of the entire bearing. At the same time, its simple assembly method also improves the installation efficiency and usability of the bearing.

[0035] Further, the rotating body includes an intermediate plate 13 and a spherical crown liner 20. The intermediate plate 13 is connected to the force-measuring and height-adjustable mechanism. The bottom surface of the intermediate plate 13 is a concave spherical surface 21, and the top surface of the spherical crown liner 20 is a convex spherical surface 22 adapted to the concave spherical surface 21. The intermediate plate 13 is rotatably arranged above the spherical crown liner 20, and the bottom surface of the spherical crown liner 20 is slidably arranged in the second pelvic cavity 9. The assembly groove 14 is opened on the side surface of the intermediate plate 13.

[0036] Specifically, as Figure 1 and Figure 2As shown, the intermediate plate 13 is a main component of the rotating body. It is connected to the force-measuring height-adjusting mechanism and plays a role in transferring and supporting. The bottom surface of the intermediate plate 13 is designed as a concave spherical surface 21, which can form a good fit with the convex spherical surface 22 of the spherical crown liner 20, so as to realize the rotation of the rotating body on the spherical crown liner 20. The spherical crown liner 20 is located below the intermediate plate 13, and its top surface is the convex spherical surface 22, which is adapted to the concave spherical surface 21 of the intermediate plate 13. The bottom surface of the spherical crown liner 20 is slidably arranged in the second pelvic cavity 9 of the second base 4, which enables the entire rotating body to slide and rotate on the second base 4. The assembly groove 14 is opened on the side surface of the intermediate plate 13 for cooperation with the second tension plate 11. When the second tension plate 11 extends into the assembly groove 14, it can effectively limit the displacement of the intermediate plate 13 (i.e., the rotating body) in the vertical direction and ensure the stability of the rotating body. The cooperation design of the concave spherical surface 21 and the convex spherical surface 22 between the intermediate plate 13 and the spherical crown liner 20 enables the rotating body to freely rotate on the spherical crown liner 20, so as to adapt to different force conditions and angle requirements. The bottom surface of the spherical crown liner 20 is slidably arranged in the second pelvic cavity 9 of the second base 4, which enables the entire rotating body to not only slide in the horizontal direction but also make fine adjustments in the vertical direction to adapt to different height requirements. By the second tension plate 11 extending into the assembly groove 14 of the intermediate plate 13, the displacement of the rotating body in the vertical direction is restricted, thereby improving the stability of the entire bearing. The design of the rotating body is compact, and the cooperation between components is tight, making the entire bearing have high structural strength and durability while maintaining its functionality. In summary, through its unique design and functions, the rotating body part of this tensile force-measuring height-adjusting bearing not only realizes the functions of rotation and sliding but also ensures the stability and safety of the entire bearing. This design enables the bearing to adapt to different force conditions and angle requirements, improving its flexibility and reliability in use.

[0037] Further, a limiting plate 10 protruding outward is provided circumferentially at the lower end of the intermediate plate 13. The bottom surface of the limiting plate 10 is an arc surface adapted to the concave spherical surface 21, and the top surface of the limiting plate 10 is an inclined surface adapted to the bottom surface of the second tension plate 11. One end of the second tension plate 11 is located above the limiting plate 10 and overlaps but does not contact. An installation plate 15 connected to the force-measuring height-adjusting mechanism is provided circumferentially at the upper end of the intermediate plate 13. The assembly groove 14 is formed between the installation plate 15 and the limiting plate 10.

[0038] Specifically, as Figure 1 and Figure 2As shown, a limiting plate 10 protruding outward is provided circumferentially at the lower end of the middle plate 13. This limiting plate 10 has two main functions: one is to cooperate with the second tensile plate 11 to limit the displacement of the rotating body in the vertical direction; the other is to fit with the concave spherical surface 21 to increase the stability of the middle plate 13 on the spherical crown lining plate 20. The bottom surface of the limiting plate 10 is designed as an arc surface adapted to the concave spherical surface 21, so that the limiting plate 10 can better fit on the convex spherical surface 22 of the spherical crown lining plate 20, increasing the smoothness and fluency of the rotation of the middle plate 13. The top surface of the limiting plate 10 is an inclined surface adapted to the bottom surface of the second tensile plate 11. The design of this inclined surface is to facilitate the second tensile plate 11 to extend into and form an overlapping but non-contact state with the limiting plate 10, which not only ensures the limiting effect but also avoids direct friction. An installation plate 15 connected to the force measuring and height adjusting mechanism is provided circumferentially at the upper end of the middle plate 13. This installation plate 15 is the key part for connecting the middle plate 13 and the force measuring and height adjusting mechanism. It bears the force from the force measuring and height adjusting mechanism and transmits these forces to the entire rotating body. The assembly groove 14 is located between the installation plate 15 and the limiting plate 10 and is the position where the second tensile plate 11 extends into and cooperates with the limiting plate 10. The design of this assembly groove 14 should consider the size and shape of the second tensile plate 11 to ensure that the two can cooperate closely without interfering with each other. The adaptation design of the limiting plate 10 and the concave spherical surface 21 increases the stability of the middle plate 13 on the spherical crown lining plate 20, making the rotating body more stable during rotation and sliding. The overlapping but non-contact design of the second tensile plate 11 and the limiting plate 10 not only ensures the limitation of the displacement of the rotating body in the vertical direction but also avoids direct friction, extending the service life. The design of the installation plate 15 makes the connection between the middle plate 13 and the force measuring and height adjusting mechanism more convenient, improving the installation efficiency of the entire support.

[0039] In summary, the design of the middle plate 13 fully considers the stability of the rotating body and the cooperation with the second tensile plate 11, making the entire tensile force measuring and height adjusting support have excellent performance while also having good installation and use convenience.

[0040] Furthermore, the force measuring and height adjusting mechanism includes a top plate 12, an adjusting block 16, and a force measuring element 17. The top surface of the top plate 12 is bolted to the upper structural member 1, and the bottom surface of the top plate 12 is bolted to the installation plates 15 on both sides of the middle plate 13. Two adjusting blocks 16 are symmetrically provided and are located between the top plate 12 and the middle plate 13. The top surface of the adjusting block 16 is in inclined surface contact with the bottom surface of the top plate 12. The force measuring element 17 is pressed between the two adjusting blocks 16, and the force measuring element 17 is electrically connected to an external controller 19.

[0041] Further, it further includes a driving mechanism 18. The driving mechanism 18 is a hydraulic jack. One end of the hydraulic jack acts on an adjusting block 16, and the other end acts on another adjusting block 16. The hydraulic jack expands and contracts horizontally to adjust the distance between the two adjusting blocks 16, thereby adjusting the height of the top plate 12.

[0042] Specifically, as Figure 1 and Figure 2 shown, the top surface of the top plate 12 is bolted to the upper structural member 1, realizing a tight connection with the upper structure. The bottom surface of the top plate 12 is bolted to the mounting plates 15 on both sides of the intermediate plate 13, ensuring a stable connection between the intermediate plate 13 and the force-measuring height-adjusting mechanism. There are two symmetrically arranged adjusting blocks 16. The adjusting blocks 16 are wedge-shaped and are located between the top plate 12 and the intermediate plate 13. Their top surfaces are in contact with the bottom surface of the top plate 12 through inclined straight surfaces. This design enables the adjusting blocks 16 to generate relative displacement when subjected to external forces, thereby realizing the adjustment function. The force-measuring element 17 is pressed between the two adjusting blocks 16 and is used to monitor the magnitude of the force between the adjusting blocks 16 in real time. The force-measuring element 17 is electrically connected to an external controller 19 and can transmit the measured force value to the controller 19 for further control and adjustment. The force-measuring element 17 uses a strain-type pressure sensor. By monitoring the horizontal force value between the adjusting blocks 16 in real time through the force-measuring element 17, and then obtaining the vertical force value of the support after mechanical conversion by the wedge-shaped adjusting blocks 16, the load condition borne by the support can be understood, providing a basis for control and adjustment. When the height needs to be adjusted, only the connection bolts between the top plate 12 and the intermediate plate 13 need to be loosened first, and then the relative displacement of the adjusting blocks 16 can be used to adjust the height of the top plate 12 to adapt to different height requirements. One end of the hydraulic jack acts on one adjusting block 16, and the other end acts on another adjusting block 16. When the hydraulic jack expands and contracts horizontally, it will push the two adjusting blocks 16 to move towards or away from each other, thereby changing the distance between them. When the two adjusting blocks 16 move relatively closer, the height of the top plate 12 rises, and vice versa, the height of the top plate 12 drops. The hydraulic jack, as the driving mechanism 18, has the advantages of stable and reliable, large force, wide adjustment range, etc., and can meet the adjustment requirements under different working conditions. The design of the entire force-measuring height-adjusting mechanism and its driving mechanism 18 enables the tensile force-measuring height-adjusting support to have functions such as real-time monitoring of the load and precise height adjustment. This design not only improves the stability and safety of the support but also increases its flexibility and convenience in use.

[0043] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Based on the technical essence of the present invention, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principles of the present invention still fall within the protection scope of the technical solution of the present invention.
