Description

Technical Field

[0001] The present application belongs to the technical field of bridge pier connectors, and in particular, relates to a bridge pier buffer connector. Background Art

[0002] During the use of the bridge, the load on the bridge is constantly changing, causing the bridge to vibrate continuously relative to the piers. Over time, the connection between the bridge and the piers will be damaged, which will affect the quality of the bridge project. Therefore, a bridge shock-absorbing bearing with a shock-absorbing function, that is, a buffer connector, is usually used to connect the bridge and the piers.

[0003] The utility model with the existing authorization announcement number CN212357956U discloses a bridge shock-absorbing bearing between a pier and a bridge, including a bridge deck and a pier located below the bridge deck, a support seat is fixedly provided on the top of the pier, and a movable seat is also provided above the pier and is sleeved on the support seat, a plurality of shock-absorbing springs are symmetrically arranged between the movable seat and the bridge deck, and a plurality of lifting rods are rotatably inserted on the bottom wall of the movable seat.

[0004] By adopting the above technical scheme, a liftable movable seat is set between the pier and the bridge deck, and the shock-absorbing spring is installed between the bridge deck and the movable seat. When the spring needs to be replaced, the movable seat can be lowered to take and place the spring, and then the movable seat can be raised to complete the replacement process without affecting the shock-absorbing effect of the spring. However, according to the above technical scheme, the bridge pier buffer connector can only buffer and absorb vibrations in the up and down directions when in use. When the vehicle on the bridge deviates to one side, causing a slight tilt between the bridge and the pier, and the thermal expansion and contraction stress of the bridge causes longitudinal deformation between the bridge and the pier, the bridge pier buffer connector cannot better absorb the longitudinal displacement, thereby affecting the buffering effect and overall service life of the bridge pier buffer connector.

[0005] To this end, we propose a bridge pier buffer connector to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-4A bridge pier buffer connector includes a chassis 1, an upper rubber column 2 is arranged above the chassis 1, six first bolts 10 are connected to the internal threads of the chassis 1, and the bottom end of each first bolt 10 passes through the chassis 1 and extends to the bottom of the chassis 1. The first bolt 10 can fix the chassis 1 on the pier, so that the device can be pre-installed on the pier to ensure the smooth connection of the bridge pier.

[0026] The bottom surface of the upper rubber column 2 is fixedly connected with the first wear-resistant plate 3, and a connecting plate 11 is arranged above the chassis 1. The bottom surface of the connecting plate 11 is fixedly connected with the bottom surface of the upper rubber column 2. The internal thread of the connecting plate 11 is connected with six second bolts 12. The top end of each second bolt 12 penetrates the connecting plate 11 and extends to the top of the connecting plate 11. The second bolts 12 cooperate with the connecting plate 11 to fix the upper rubber column 2 to the bottom of the bridge, so that it can be smoothly combined with the bridge pier, thereby ensuring the normal use of the device.

[0027] The outer surface of the first wear-resistant plate 3 is fixedly connected with a fixed cover 4, a lower rubber column 5 is arranged inside the fixed cover 4, and the upper surface of the fixed cover 4 is fixedly connected with a reinforcement ring 13. The inner wall of the reinforcement ring 13 is fixedly connected to the outer surface of the upper rubber column 2. The reinforcement ring 13 can increase the connection firmness between the fixed cover 4 and the upper rubber column 2, so that the fixed cover 4 is not easy to loosen.

[0028] The bottom surface of the lower rubber column 5 is fixedly connected to the upper surface of the chassis 1, and the inner wall of the fixed cover 4 is fixedly connected with a sealing rubber ring 14. The inner wall of the sealing rubber ring 14 is fixedly connected to the outer surface of the lower rubber column 5. By utilizing the elastic force of the sealing rubber ring 14 itself, the gap between the fixed cover 4 and the lower rubber column 5 can be closed without affecting the horizontal displacement buffering of the fixed cover 4, thereby reducing the influence of dust and impurities on the inside of the fixed cover 4.

[0029] The upper surface of the lower rubber column 5 is fixedly connected to the second wear-resistant plate 6, and a plurality of balls 7 are clamped on the upper surface of the second wear-resistant plate 6. The outer surface of each ball 7 is in contact with the bottom surface of the first wear-resistant plate 3. Six fixed plates 8 are fixedly connected to the upper surface of the chassis 1. A side of each fixed plate 8 close to the fixed cover 4 is fixedly connected to a reinforcement block 15. The bottom surface of each reinforcement block 15 is fixedly connected to the upper surface of the chassis 1. The reinforcement block 15 can increase the connection firmness between the fixed plate 8 and the chassis 1, make the connection between the fixed plate 8 and the chassis 1 tighter, and improve the pressure-bearing capacity of the fixed plate 8.

[0030] A first spring damper 9 is movably hinged on a side of each fixing plate 8 close to the fixing cover 4, and an end of each first spring damper 9 away from the fixing plate 8 is movably hinged to the outer surface of the fixing cover 4. Six support plates 16 are fixedly connected to the outer surface of the fixing cover 4, and a first cross universal joint 17 is fixedly connected to the bottom surface of each support plate 16. A second spring damper 18 is fixedly connected to the bottom surface of each first cross universal joint 17, and a second spring damper 19 is fixedly connected to the bottom surface of each second spring damper 18. By cooperating with the universal movement of the first cross universal joint 17 and the second cross universal joint 19 through the support plate 16 and the damping provided by the second spring damper 18, the upper and lower pressure bearing strength of the fixing cover 4 and the upper rubber column 2 can be improved without affecting the smooth horizontal movement of the fixing cover 4.

[0031] The bottom surface of each second cross universal joint 19 is fixedly connected to a limiting seat 20, and the bottom surface of each limiting seat 20 is fixedly connected to the upper surface of the chassis 1. The limiting seat 20 can limit the position of the second cross universal joint 19, so that the second cross universal joint 19 can be firmly located at a suitable position on the chassis 1, thereby ensuring the normal use of the second cross universal joint 19.

[0032] The working principle of the utility model is as follows: when in use, firstly, the lower rubber column 5 is fixed on the bridge pier through the first bolt 10 in cooperation with the chassis 1, and then the upper rubber column 2 is fixed to the bottom of the bridge by the second bolt 12 and the connecting plate 11. After the upper rubber column 2 and the lower rubber column 5 are docked, the lower rubber column 5 cooperates with the second wear-resistant plate 6 and the ball 7 on the second wear-resistant plate 6, so that the bridge pier can smoothly bear the upper and lower pressures transmitted from the upper rubber column 2 and the first wear-resistant plate 3. At the same time, when the bridge has longitudinal deformation between the bridge and the pier due to thermal expansion and contraction stress or uneven force, the first wear-resistant plate 3 can also be used to offset the relative sliding between the ball 7 and the second wear-resistant plate 6, so that the bridge pier buffer connector can better absorb the longitudinal displacement, prevent the bridge pier buffer connector from being damaged due to the longitudinal displacement, greatly increase the overall buffering effect and service life of the bridge pier buffer connector, and through the fixing plate 8 cooperates with the first spring damper 9 and the fixed cover 4, as well as the assistance of the reinforcement block 15, when the upper rubber column 2 and the first wear-resistant plate 3 are displaced due to the longitudinal force, the damping provided by the first spring damper 9 and the movable hinge relationship between the first spring damper 9 and the fixed plate 8 and the fixed cover 4 can effectively absorb the displacement deformation in all horizontal directions, and can limit the displacement distance of the upper rubber column 2 and the first wear-resistant plate 3 to prevent loosening, so that the bridge pier buffer connector can further absorb and buffer the longitudinal displacement force, thereby ensuring the stability of the bridge pier buffer connector. Finally, through the support plate 16, in cooperation with the universal activity of the first cross universal joint 17 and the second cross universal joint 19, as well as the damping provided by the second spring damper 18 and the fixation of the second cross universal joint 19 by the limit seat 20, the upper and lower pressure bearing strength of the fixed cover 4 and the upper rubber column 2 can be improved without affecting the smooth horizontal movement of the fixed cover 4.
