Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing and buffering supports, in particular to a shock-absorbing and buffering support for highway bridge construction. Background Art

[0002] The shock-absorbing and buffering bearing of a highway bridge refers to a supporting device set up in the structure to meet the seismic isolation requirements. It is a structural component with small horizontal stiffness and large vertical stiffness. It can be used as part of the load-bearing system. Its function is to withstand various forces acting on the superstructure and reliably transmit them to the piers. It is an important force transmission device of the bridge.

[0003] The Chinese utility model patent application number: CN202220999513.8 discloses a shock-absorbing buffer bearing for highway bridge construction. The overall buffering effect is further improved through the two-layer buffering effect, and the upper part of the structure will not loosen due to vibration. There is no need for regular inspection in the later stage, and it is more convenient to use.

[0004] While the aforementioned patent achieves the effect of shock absorption and buffering for highway bridges, it suffers from the following drawbacks: The metal components of the shock-absorbing and buffering bearings for highway bridge construction, such as the buffer springs, are exposed to the outside world during use. Rainwater flowing down the bridge easily corrodes the metal components, reducing their service life and making them inconvenient to use. Therefore, we propose a shock-absorbing and buffering bearing for highway bridge construction. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a shock-absorbing and buffering bearing for highway bridge construction, which solves the problem that metal parts such as buffer springs are exposed to the outside world when the shock-absorbing and buffering bearing is used for highway bridge construction, and rainwater flowing down the bridge can easily corrode the metal parts, thereby reducing their service life.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The top of the connecting seat is fixedly connected to the first supporting seat, and the bottom of the connecting seat is symmetrically connected to the bottom of the connecting seat. It is connected to a second support seat, and the connecting rod is rotatably connected to the second support seat; when in use, when passing vehicles apply downward pressure on the highway bridge, the top plate will be forced to move downward, thereby driving the second support seat to move, and the movement of the second support seat drives the connecting rod to rotate, and then drives the first support seat and the adjustment plate to slide, and cooperates with the first shock-absorbing spring to achieve a shock-absorbing and buffering effect. At the same time, when subjected to downward pressure, the lifting plate will drive the connecting seat to slide along the buffer seat through the connecting rod, and the second shock-absorbing spring is compressed, thereby achieving a further shock-absorbing and buffering effect. The arrangement of the first protective frame and the second protective frame can protect the metal parts of the device to prevent them from being affected by moisture and causing corrosion, thereby increasing the service life of the device.

[0008] Preferably, a protective ring is symmetrically fixedly connected to the top of the base plate, and a protective cover is threadedly connected to one end of the protective ring. The arrangement of the protective cover and the protective ring can protect the bolts on the outside of the base plate.

[0009] Preferably, the inner wall of the first protective frame is symmetrically fixedly connected with a limiting slide bar, and the lifting plate is slidably connected to the limiting slide bar. The setting of the limiting slide bar can limit the movement of the lifting plate to prevent deviation.

[0010] Preferably, a first damper is provided equidistantly between the lifting plate and the first protective frame. The first damper can be used in conjunction with the second shock-absorbing spring to achieve a shock-absorbing and buffering effect.

[0011] Preferably, a fixed plate is symmetrically fixedly connected to the top of the lifting plate, a fixed rod is equidistantly fixedly connected between the two fixed plates, the adjusting plate is slidably connected to the fixed rod, and a first shock-absorbing spring is sleeved on the outside of the fixed rod and on one side of the adjusting plate. The movement of the adjusting plate can be limited by the setting of the fixed rod, and the first shock-absorbing spring will be squeezed by the movement of the adjusting plate, thereby achieving a shock-absorbing and buffering effect.

[0012] Preferably, a second damper is provided equidistantly between the lifting plate and the top plate, and the second damper can be used in conjunction with the first shock-absorbing spring to achieve a shock-absorbing and buffering effect.

[0013] The utility model provides a shock-absorbing and buffering support for highway bridge construction. Compared with the existing technology, it has the following advantages:

[0014] 1. The shock-absorbing and buffering bearing for highway bridge construction realizes the function of preliminary shock absorption and buffering of highway bridges by arranging a second support seat, a connecting rod, a first support seat, an adjustment plate, a first shock-absorbing spring and a second damper.

[0015] 2. The shock-absorbing and buffering support for highway bridge construction realizes the function of further shock absorption and buffering of highway bridges by arranging a lifting plate, a connecting rod, a buffer seat, a connecting seat, a second shock-absorbing spring and a first damper, and has a good buffering effect.

[0016] 3. The shock-absorbing and buffering support for highway bridge construction realizes the function of protecting the metal parts of the device by setting the first protection frame and the second protection frame, thereby increasing the service life of the device and facilitating use.
