Description

Technical Field

[0001] The utility model relates to the field of bridge support technology equipment, in particular to an upper guide basin support. Background Art

[0002] As one of the core components of bridge engineering, bridge bearings play a key role in transferring and distributing the heavy load of the bridge superstructure to the bridge foundation. In response to the general background of energy conservation, emission reduction and carbon neutrality, adjusting the product production structure, reducing resource consumption and reducing costs have become key measures to enhance the market competitiveness of bearings, and the design and material selection of bearings are often related to the stability, durability and safety of bridges. Taking the pot-type rubber bearing as an example, the mainstream structure is to adopt an intermediate guide sliding structure, which can effectively adapt to the smooth transition of horizontal forces under the corner state. However, the intermediate guide structure in the prior art requires the installation of an intermediate guide bar, and through holes and threaded holes are set on the piston plate, which not only increases the complexity of processing and resource loss, but also leads to a large amount of steel. In addition, in order to achieve the horizontal force transition with the intermediate guide bar, the top plate is also designed with a guide slide, which further increases the thickness and steel consumption of the top plate; the traditional pot-type rubber bearing has the problems of large steel consumption and complex processing procedures in the design and manufacturing process, which not only increases the cost but also leads to higher carbon emissions.

[0003] For example, Chinese patent CN208055859U discloses an anti-seismic basin-type bearing for a light rail bridge, comprising an upper seat plate, an intermediate lining plate, a pressure-bearing rubber plate and a lower seat plate. The lower seat plate is provided with an annular baffle, the pressure-bearing rubber plate is located in the annular baffle on the lower seat plate, the intermediate lining plate is located on the pressure-bearing rubber plate, and the lower part of the intermediate lining plate is matched with the gap between the annular baffle and the upper structure, which can meet the actual working conditions of the bearing to adapt to the free deformation of the beam body and the upper structure, make its force scientific, and increase the life of the bearing. However, the above-mentioned seismic basin-type bearing for light rail bridge has the following deficiencies in its specific application: first, the middle lining of the bearing adopts an integrated structure, and its top two sides are embedded in the baffles arranged on both sides of the lower part of the top plate. This design requires processing baffles on the top plate to fix the middle lining, which not only increases the processing steps, but also increases the amount of steel used due to the lengthening of the baffles. Longer baffles mean more material usage and processing time, thereby increasing production costs and carbon emissions. At the same time, due to the integrated structural design of the middle lining, the processing and assembly process becomes more complicated. The complexity of the design directly affects the production efficiency, increases the manufacturing cost, and also increases the energy consumption in the manufacturing process, resulting in poor practicality.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0008] Furthermore, in order to improve the durability of the entire pot-type support, reduce wear, and ensure the effective transmission of load under complex stress conditions, the upper guide mechanism includes a circular wear-resistant plate arranged at the bottom end of the friction plate, a circular through hole is opened in the middle of the top end of the circular wear-resistant plate, an intermediate guide plate is arranged at the bottom end of the circular wear-resistant plate, an intermediate guide groove is opened at the top end of the intermediate guide plate, U-shaped baffles are symmetrically arranged on both sides of the intermediate guide groove, a lubrication strip is arranged on one side of the U-shaped baffle, a circular fixing groove matching the circular wear-resistant plate is opened in the middle of the top end of the intermediate guide groove, a shear pin matching the circular through hole is arranged through the middle of the top end of the circular fixing groove, and the cross-section of the shear pin is arranged as a convex structure.

[0009] Furthermore, in order to optimize the sealing and shock absorbing capabilities of the support and ensure the stability of the entire basin-type support structure, the piston plate mechanism includes a piston plate arranged at the bottom end of the upper guide mechanism, a circular pin hole matching the shear pin is opened at the top end of the piston plate, a sealing assembly is arranged at the bottom end of the piston plate, the sealing assembly includes a circular support plate arranged at the bottom end of the piston plate, a circular gasket is arranged at the top end of the circular support plate, a sealing ring is arranged on the outside of the circular gasket, a plurality of annular gaskets are arranged from the inside to the outside in the middle of the top end of the circular gasket, and a plurality of friction holes arranged in a circle are opened at the top end of the circular gasket.

[0010] Furthermore, in order to provide stable and reliable support and realize effective coordination and force transmission between various components, the basin-type support assembly includes a support base plate arranged at the bottom end of the piston plate mechanism, an upper guide basin is arranged at the top end of the support base plate, and a circular support groove cooperating with the piston plate mechanism is opened in the middle of the top end of the upper guide basin.

At the same time, it can realize horizontal rotation through the cooperation of the piston plate mechanism and the pot-type support assembly, so as to adapt to the installation conditions of different angles at the bottom of the inclined bridge.

[0013] 2. By setting up the upper guide mechanism, the middle guide plate and the piston plate mechanism are rotatably connected through the shear pin, so that the middle guide plate can be rotated from 0 to 360 degrees in the horizontal direction through the shear pin, which can adapt to the installation conditions at different angles at the bottom of the inclined bridge and increase the practicality of the entire support.

[0014] 3. By setting up the piston plate mechanism and the pot-type bearing assembly, the piston plate mechanism can be used to reduce vibration and displacement when the dynamic load changes, thereby maintaining the reliability of the entire bearing. In addition, in conjunction with the pot-type bearing assembly, the uniformity and accuracy of the load transfer and force distribution of the entire bearing can be ensured, which helps to optimize the performance of the entire upper guide pot-type bearing and ensure the safety and reliability of the bridge structure during the load-bearing process.

[0024] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] According to an embodiment of the utility model, an upper guide basin-type support is provided.

[0026] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 6 As shown, according to the configuration method of the embodiment of the utility model, it includes a supporting top plate 1, and fixing bars 2 are symmetrically arranged on both sides of the supporting top plate 1 (in addition, in specific applications, the fixing bars 2 and the friction plates 3 are made of stainless steel), and the bottom end of the supporting top plate 1 is provided with a friction plate 3, and the bottom end of the friction plate 3 is provided with an upper guide mechanism 4, and the bottom end of the upper guide mechanism 4 is provided with a piston plate mechanism 5, and the bottom end of the piston plate mechanism 5 is provided with a pot-type support assembly 6.

[0027] With the aid of the above-mentioned technical scheme of the utility model, the structure of the utility model is scientific and novel. Under the premise of ensuring the perfect transition of the horizontal force, the upper guide mechanism 4 can be accurately adjusted to reduce the thickness of the supporting top plate 1, and the horizontal rotation can be realized through the cooperation of the piston plate mechanism 5 and the pot-type support assembly 6, thereby adapting to the installation conditions of different angles at the bottom of the inclined bridge.

[0028] In one embodiment, for the upper guide mechanism 4, the upper guide mechanism 4 includes a circular wear-resistant plate 401 arranged at the bottom end of the friction plate 3, a circular through hole 402 is opened in the middle of the top end of the circular wear-resistant plate 401 (in addition, in specific applications, the circular through hole 402 is filled with 5201 silicone grease), an intermediate guide plate 403 is arranged at the bottom end of the circular wear-resistant plate 401, an intermediate guide groove 404 is opened at the top end of the intermediate guide plate 403, and U-shaped baffles 405 are symmetrically arranged on both sides of the intermediate guide groove 404. A lubricating strip 406 is provided on one side of the U-shaped baffle 405 (in addition, in specific applications, the lubricating strip 406 adopts a polytetrafluoroethylene copper-based sliding strip), a circular fixing groove 407 matching the circular wear-resistant plate 401 is provided in the middle of the top of the intermediate guide groove 404, a shear pin 408 matching the circular through hole 402 is penetrated in the middle of the top of the circular fixing groove 407, and the cross-section of the shear pin 408 is set as a convex structure, thereby improving the durability of the entire pot-type support and ensuring the effective transfer of load under complex stress conditions.

[0029] The working principle of the upper guide mechanism 4 is as follows: first, through the setting of the circular wear-resistant plate 401, the upper guide mechanism 4 directly contacts the friction plate 3, and can withstand repeated load transfer for a long time, thereby improving the durability of the entire support. The 5201 silicone grease filled in the circular through hole 402 can increase the service life of the circular wear-resistant plate 401 and increase the service life of the support; then, the middle guide plate 403 cooperates with the middle guide groove 404, and the U-shaped baffles 405 on both sides of the guide groove 404 provide an effective way for the smooth transition of horizontal forces. This structure can ensure the smooth transmission of force when the bridge is subjected to horizontal thrust, such as wind load or earthquake force, and reduce structural damage caused by sudden changes in force. In addition, the lubricating strip 406 adopts a polytetrafluoroethylene-based copper-based sliding strip, which has the excellent low friction coefficient and chemical stability of polytetrafluoroethylene, and is combined with The excellent thermal conductivity and mechanical strength of copper alloy are utilized, thereby further reducing friction and wear, ensuring smooth movement and low maintenance requirements of the bearing during long-term use; then, the shear pin 408 is used in conjunction with the circular through hole 402 and the circular fixing groove 407 to provide a stable and reliable connection method to keep the upper guide mechanism 4 in a stable position during movement or force. The middle guide plate 403 can be rotated horizontally from 0 to 360 degrees through the shear pin 408, and the convex cross-sectional design of the shear pin increases the contact area, thereby improving the stability and strength of the connection. Different from the integrated structure of the prior art, the design of the upper guide mechanism 4 makes the entire bearing easy to install and maintain without large-scale disassembly of the entire bearing, which not only reduces maintenance costs, but also reduces the downtime of the bridge during maintenance.

[0030] In one embodiment, for the above-mentioned piston plate mechanism 5 and pot-type support assembly 6, the piston plate mechanism 5 includes a piston plate 501 arranged at the bottom end of the upper guide mechanism 4, a circular pin hole 502 matching with the shear pin 408 is opened at the top end of the piston plate 501, a sealing assembly 503 is arranged at the bottom end of the piston plate 501, and the sealing assembly 503 includes a circular support plate 5031 arranged at the bottom end of the piston plate 501, a circular gasket 5032 is arranged at the top end of the circular support plate 5031 (in addition, in specific applications, the circular gasket 5032 and the annular gasket 5034 are made of rubber), and a sealing ring 5033 is arranged on the outer side of the circular gasket 5032 ( In addition, in specific applications, the sealing ring 5033 is made of brass), a plurality of annular gaskets 5034 are arranged from the inside to the outside in the middle of the top of the circular gasket 5032, and a plurality of friction holes 5035 arranged in a circle are opened at the top of the circular gasket 5032; the pot-type support assembly 6 includes a support base plate 601 arranged at the bottom end of the piston plate mechanism 5, an upper guide basin 602 is arranged at the top of the support base plate 601, and a circular support groove 603 matching the piston plate mechanism 5 is opened in the middle of the top of the upper guide basin 602, thereby optimizing the sealing and shock absorbing capabilities of the support, ensuring the stability of the entire pot-type support structure, and realizing effective coordination and force transmission between the components.

[0031] The working principle of the piston plate mechanism 5 and the pot-type support assembly 6 is as follows: first, the piston plate 501 is used in combination with the sealing assembly 503, especially through the arrangement of the circular gasket 5032 and the annular gasket 5034, which provides good shock-absorbing performance. This shock-absorbing design helps to absorb and disperse the impact force in the load transmitted through the support, especially when encountering heavy loads or sudden loads, and can effectively reduce the wear on bridges and other structures; at the same time, the circular pin hole 502 at the top of the piston plate 501 and the shear pin 408 are used in combination, which not only ensures the precise connection between the piston plate mechanism 5 and the upper guide mechanism 4, but also ensures the effective and accurate transmission of the load in the entire support; the sealing assembly 503 can increase the friction between the interacting surfaces through the several annular gaskets 5034 at the top of the circular gasket 5032 and the friction holes 5035 arranged in a circle. , preventing the piston plate mechanism 5 from sliding relative to each other under load, the combined use of the sealing ring 5033 and the circular support plate 5031 not only increases the sealing performance, but also improves the stability of the entire system by increasing the friction of the contact surface. The piston plate mechanism 5 can reduce vibration and displacement when the dynamic load changes, thereby maintaining the reliability of the entire bearing; the bearing base plate 601, as the basic component of the entire basin-type bearing, undertakes the important task of safely and effectively transferring the load of the upper structure to the lower structure. The upper guide basin 602 not only provides an accurate positioning and support point for the piston plate mechanism 5, but the circular support groove 603 at the top is used in conjunction with the piston plate mechanism 5 to further ensure the uniformity and accuracy of the load transfer and force distribution of the entire basin-type bearing, which helps to optimize the performance of the entire bearing and ensure the safety and reliability of the bridge structure during movement and load-bearing.

[0032] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0033] In actual application, the supporting top plate 1 transmits the horizontal force from the top bridge to the upper guide mechanism 4 through the fixed bar 2 (the working principle of the upper guide mechanism 4 is as described above), and the horizontal force in the upper guide mechanism 4 is transmitted to the middle guide plate 403 through the U-shaped baffle 405, and then the stress is transmitted to the shear pin 408 through the circular through hole 402 in the center of the middle guide plate 403, and the convex structure of the shear pin 408 is used to transmit the stress to the top of the piston plate mechanism 5 (the working principle of the piston plate mechanism 5 is as described above), and the piston plate mechanism 5 transmits the horizontal force to the pot-type support assembly 6 through the sealing assembly 503 (the working principle of the support assembly 6 is as described above), thereby achieving a perfect transition of horizontal force transmission.
