Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing and protective devices, in particular to a bridge structure suspension rod shock-absorbing and protective device. Background Art

[0002] Bridge hangers are an important component of bridge structures, mainly used to bear and transfer loads and maintain the stability of the bridge structure. Hangers are usually made of steel, and their shape and size depend on the design and load conditions of the bridge.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the existing bridge hangers are subjected to external impacts or vibrations such as earthquakes, the shock-absorbing effect of the hangers is poor, and the hangers cannot effectively absorb and disperse external forces, which intensifies the bumps and vibrations of the bridge deck, thereby accelerating the fatigue failure of the bridge structure, causing damage to the bridge structure or even collapse. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing bridge hangers in the prior art have poor shock-absorbing effect when subjected to external impact or vibration such as earthquake. The hangers cannot effectively absorb and disperse external forces, which aggravates the bumps and vibrations of the bridge deck. For this reason, we propose a bridge structure hanger shock-absorbing protection device.

[0005] In order to achieve the above-mentioned objectives, the present application adopts the following technical solutions: a bridge structure hanger shock-absorbing protection device, comprising a bridge frame, the top of the bridge frame is fixedly connected to a base, the front end and the rear end of the base are both provided with a first rotation hole, the interior of the first rotation hole is rotatably connected to a first rotating shaft, the surface of the first rotating shaft is fixedly connected to a first rotating support, the top of the first rotating support is fixedly connected to a connecting block, the top of the connecting block is fixedly connected to a second rotating support, the left and right sides of the second rotating support are fixedly connected to a second rotating shaft, a U-shaped seat is installed on the surface of the second rotating shaft, second rotation holes are provided on both sides of the U-shaped seat, the surface of the second rotating shaft is rotatably connected to the interior of the second rotating hole, and the top of the U-shaped seat is fixedly connected to a hanger body.

[0006] Preferably, a connecting seat is fixedly connected to the top of the boom body, a through hole is provided on the surface of the connecting seat, a cable is slidably connected inside the through hole, and two fixing blocks are fixedly connected to the surface of the cable.

[0007] Preferably, a buffer spring is fixedly connected to one side of the fixing block, and a buffer plate is fixedly connected to one side of the buffer spring.

[0008] Preferably, bearings are installed inside the first rotating hole and the second rotating hole.

[0009] Preferably, the material of the suspension rod body is carbon fiber composite material.

[0010] Preferably, the first rotating support and the second rotating support are made of titanium alloy.

[0011] Technical effects and advantages of the utility model:

[0012] In the utility model, when the boom body is affected by the outside world, the boom body drives the second rotating shaft and the second rotating support inside the U-shaped seat at the bottom to swing back and forth. When the second rotating support swings back and forth, the first rotating support located below the second rotating support will swing left and right at the same time, thereby reducing the swinging effect of the boom body when it is affected by the outside world, thereby increasing the anti-seismic effect of the boom body.

[0019] Reference Figure 1 , Figure 2As shown, the utility model provides a technical solution: a bridge structure suspender shock-absorbing protection device, including a bridge frame 1, the top of the bridge frame 1 is fixedly connected to a base 2, the front end and the rear end of the base 2 are both provided with a first rotating hole 3, the interior of the first rotating hole 3 is rotatably connected to a first rotating shaft 4, the surface of the first rotating shaft 4 is fixedly connected to a first rotating support 5, the top of the first rotating support 5 is fixedly connected to a connecting block 6, the top of the connecting block 6 is fixedly connected to a second rotating support 7, the left side and the right side of the second rotating support 7 are both fixedly connected to a second rotating shaft 8, the surface of the second rotating shaft 8 is installed with a U-shaped seat 9, and the U-shaped seat 9 A second rotating hole 10 is opened on both sides, and the surface of the second rotating shaft 8 is rotatably connected to the inside of the second rotating hole 10. The top of the U-shaped seat 9 is fixedly connected to the boom body 11. When the boom body 11 is affected by the outside world, the boom body 11 drives the second rotating shaft 8 and the second rotating support 7 inside the U-shaped seat 9 at the bottom to swing back and forth. When the second rotating support 7 swings back and forth, the first rotating support 5 located below the second rotating support 7 will swing left and right at the same time, so that the swinging effect of the boom body 11 is reduced when it is affected by the outside world, thereby increasing the anti-seismic effect of the boom body 11.

[0020] Reference Figure 1 , Figure 3 As shown, in this embodiment: a connecting seat 12 is fixedly connected to the top of the boom body 11, a through hole 13 is opened on the surface of the connecting seat 12, a cable 14 is slidably connected inside the through hole 13, and two fixing blocks 15 are fixedly connected to the surface of the cable 14. When the connecting seat 12 at the top of the boom body 11 swings left and right on the surface of the cable 14, two fixing blocks 15 are fixedly connected to the surface of the cable 14, so that when the connecting seat 12 swings left and right, the inner wall of the fixing block 15 will limit the two sides of the connecting seat 12.

[0021] Reference Figure 4 As shown, in this embodiment: a buffer spring 17 is fixedly connected to one side of the fixed block 15, and a buffer plate 18 is fixedly connected to one side of the buffer spring 17. By arranging the buffer spring 17 and the buffer plate 18 on the inner wall of the fixed block 15, the two sides of the connecting seat 12 can play a buffering role when colliding with the inner wall of the fixed block 15, thereby protecting the connecting seat 12.

[0022] Reference Figure 2 As shown, in this embodiment: bearings 16 are installed inside the first rotating hole 3 and the second rotating hole 10.

[0023] Reference Figure 1As shown, in this embodiment: the material of the hanger body 11 is carbon fiber composite material. Compared with traditional metal materials, carbon fiber composite materials are lighter in weight but have high strength and rigidity. This makes the products made of carbon fiber composite materials have higher strength, can reduce structural loads and improve overall performance.

[0024] Reference Figure 1 As shown, in this embodiment: the material of the first rotating support 5 and the second rotating support 7 is titanium alloy. Titanium alloy has a lighter density but high strength. This makes it possible to reduce structural loads by using titanium alloy while maintaining high strength and rigidity, thereby increasing the service life of the device.

[0025] Working principle of the utility model: when the boom body 11 is affected by the outside world, the boom body 11 drives the second rotating shaft 8 and the second rotating support 7 inside the U-shaped seat 9 at the bottom to swing back and forth. When the second rotating support 7 swings back and forth, the first rotating support 5 located below the second rotating support 7 will swing left and right at the same time, so that the swinging effect of the boom body 11 is reduced when it is affected by the outside world, thereby increasing the anti-seismic effect of the boom body 11. When the connecting seat 12 at the top of the boom body 11 swings left and right on the surface of the cable 14, two fixed blocks 15 are fixedly connected to the surface of the cable 14, so that when the connecting seat 12 swings left and right, the inner wall of the fixed block 15 will limit the two sides of the connecting seat 12, and a buffer spring 1 is set on the inner wall of the fixed block 15 7 and the buffer plate 18, so that the two sides of the connecting seat 12 play a buffering role when colliding with the inner wall of the fixing block 15, thereby protecting the connecting seat 12, by installing bearings 16 inside the first rotating hole 3 and the second rotating hole 10, the friction between the first rotating shaft 4 and the second rotating shaft 8 is reduced when rotating, thereby increasing the service life. Compared with traditional metal materials, carbon fiber composite materials are lighter in weight but have high strength and rigidity, which makes the products made of carbon fiber composite materials have higher strength, can reduce structural loads and improve overall performance. Titanium alloy has a lighter density but high strength, which makes the use of titanium alloy can reduce structural loads while maintaining high strength and rigidity, thereby increasing the service life of the device.
