The second semicircular plate 411 is provided on the surface of the connecting rod 2. When the disassembly device 4 is used, that is, when the foam plate 402 is corroded due to long-term wind and sun exposure, the old foam plate 402 is removed, and the surface of the connecting rod 2 is sleeved by the first semicircular plate 408 and the second semicircular plate 411, and then the new foam plate 402 is fixed to the surface of the guardrail, so that the shock-absorbing device with the foam plate 402 as the main body can be easily replaced, thereby avoiding the impact of the shock-absorbing effect due to the corrosion of the foam plate 402.
[0030] The end of the connecting plate 401 away from the foam board 402 is fixedly connected to a rectangular block 407, and a rotating rod 409 is rotatably inserted on the side of the rectangular block 407. The end of the rotating rod 409 away from the rectangular block 407 is fixedly connected to a connecting strip 410, and the end of the connecting strip 410 away from the rotating rod 409 is fixedly connected to the second semicircular plate 411. The connecting strip 410 is manually controlled to rotate on the surface of the rotating rod 409, and the second semicircular plate 411 can be rotated to be mounted on the surface of the connecting rod 2.
[0031] A U-shaped plate 412 is fixedly connected to one side of the connecting plate 401 away from the foam plate 402, and the inner wall of the U-shaped plate 412 is slidably connected to the connecting strip 410. A fixing rod 413 is slidably inserted into one side of the U-shaped plate 412, and a spring 414 is sleeved on the surface of the fixing rod 413. One end of the spring 414 is fixedly connected to the top of the fixing rod 413, and one end of the spring 414 away from the top of the fixing rod 413 is fixedly connected to the side of the U-shaped plate 412. After the second semicircular plate 411 is sleeved on the surface of the connecting rod 2, the fixing rod 413 is inserted into the inside of the U-shaped plate 412, and then the top of the fixing rod 413 is pulled by the spring 414, and then the fixing rod 413 is restricted inside the U-shaped plate 412, and then the connecting strip 410 that slides into the inside of the U-shaped plate 412 is restricted inside the U-shaped plate 412.
[0032] One end of the foam board 402 close to the connecting plate 401 is fixedly connected with a connecting belt 403, and a Velcro mother patch 404 is fixedly connected to the surface of the foam board 402, and a Velcro sub-patch 406 is fixedly connected to one side of the foam board 402. The end of the foam board 402 close to the connecting plate 401 is fixedly connected to a connecting frame 405, and the inner wall of the connecting frame 405 is slidably connected to the connecting belt 403. The connecting belt 403 is passed around the connecting rod 2 provided at the bottom of the support frame 1, and then the connecting belt 403 is inserted into the interior of the connecting frame 405, and then the Velcro sub-patch 406 and the Velcro mother patch 404 are pasted together, and then the bottom of the foam board 402 is fixed to the surface of the connecting rod 2.
[0033] Reference Figure 4The supporting device 5 includes a connecting block 501, which is sleeved on the surface of the supporting frame 1. Both sides of the connecting block 501 are fixedly connected with inclined rods 502, and the bottom of the inclined rods 502 is fixedly connected with a rectangular plate 503. When using the supporting device 5, the connecting block 501 is directly sleeved on the surface of the supporting frame 1, and then the supporting frame 1 is supported by the inclined rods 502 and the rectangular plates 503. Then, the supporting frame 1 can be set on the surface of the bridge deck 3 by welding. After welding is completed, the connecting block 501 can be removed from the surface of the supporting frame 1. A sliding groove 504 is opened on one side of the connecting block 501, and a moving plate 505 is slidably connected to the inner wall of the sliding groove 504. By controlling the moving plate 505 to slide inside the sliding groove 504, the supporting frame 1 can be clamped by the inner wall of the connecting block 501 and the moving plate 505, so that the connecting block 501 is well fixed to the surface of the supporting frame 1.
[0034] Preferably, a first rubber strip 507 is evenly fixedly connected to one side of the movable plate 505, and a second rubber strip 506 is evenly fixedly connected to the inner wall of the connecting block 501. The functions of the first rubber strip 507 and the second rubber strip 506 are to increase friction, thereby preventing the connecting block 501 from sliding on the surface of the support frame 1.
[0035] A support block 508 is fixedly connected to one side of the connecting block 501, and a threaded rod 509 is rotatably inserted through the side of the support block 508. The threaded rod 509 is threadedly inserted into the side of the movable plate 505. The thread directions of the threaded rod 509 from the middle to both sides are opposite. Because the thread directions of the threaded rod 509 from the middle to both sides are opposite, when the threaded rod 509 is rotated, the movable plate 505 can be controlled to move relative to or opposite to each other inside the slide groove 504 at the same time.
[0036] The specific working process of this embodiment is as follows:
[0037] When using the steel bridge guardrail, the steel bridge guardrail and the bridge deck 3 of the steel bridge are directly welded, so as to provide good protection for both sides of the steel bridge to prevent pedestrians or vehicles on the steel bridge from falling off the bridge. When using the disassembly device 4, that is, when the foam board 402 is corroded due to long-term wind and sun exposure, the old foam board 402 can be disassembled, and then the first semicircular plate 408 on the back of the new shock-absorbing device with the foam board 402 as the main body is sleeved on the surface of the connecting rod 2, and then the connecting strip 410 is manually controlled to rotate on the surface of the rotating rod 409, and then the second semicircular plate 411 can be sleeved on the surface of the connecting rod 2 by rotation. After the second semicircular plate 411 is sleeved on the surface of the connecting rod 2, the fixing rod 413 is inserted into the inside of the U-shaped plate 412, and then the spring is used to The top of the fixed rod 413 is pulled by 414, thereby restricting the fixed rod 413 inside the U-shaped plate 412, and then restricting the connecting strip 410 that slides into the inside of the U-shaped plate 412 inside the U-shaped plate 412, so that the surface of the connecting rod 2 is covered by the first semicircular plate 408 and the second semicircular plate 411, and then the connecting belt 403 is passed around the bottom of the support frame 1 with the connecting rod 2, and then the connecting belt 403 is inserted into the inside of the connecting frame 405, and then the Velcro sub-sticker 406 and the Velcro mother sticky 404 are pasted together, so that the bottom of the foam board 402 is fixed to the surface of the connecting rod 2, and then the new foam board 402 is fixed to the surface of the guardrail, so that the shock absorbing device with the foam board 402 as the main body can be replaced very conveniently to avoid the shock absorbing effect being affected by the corrosion of the foam board 402.
[0038] When using the supporting device 5, the connecting block 501 is directly sleeved on the surface of the supporting frame 1. Because the thread directions of the threaded rod 509 from the middle to both sides are opposite, when the threaded rod 509 is rotated, the movable plate 505 can be controlled to move relative to or away from each other inside the sliding groove 504 at the same time, and then the threaded rod 509 is rotated to make the movable plate 505 move away from each other, and then the connecting block 501 is fixed to the surface of the supporting frame 1 through the extrusion of the movable plate 505, and then the supporting frame 1 can be supported by the inclined rod 502 and the rectangular plate 503, and then the supporting frame 1 can be well set on the surface of the bridge deck 3 through welding. After the welding is completed, the threaded rod 509 is rotated in the opposite direction to make the movable plate 505 away from the inner wall of the connecting block 501, and then the connecting block 501 can be removed from the surface of the supporting frame 1, which will not affect the use of the guardrail.
