Description

Technical Field

[0001] The utility model belongs to the technical field of bridges, and in particular relates to a shock-absorbing base for bridges. Background Art

[0002] Bridges generally refer to structures erected across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; supports are force transmission devices installed at the supporting locations of the span structure and piers or abutments; ancillary structures refer to bridgehead slabs, conical slope protection, revetments, diversion projects, etc.

[0003] During the construction of a small bridge, the span of the bridge is small and is only for pedestrians to pass. During construction, a base needs to be installed on both sides to support the bridge. A shock-absorbing device needs to be installed at the connection position between the bridge and the base, but the shock-absorbing device and the bridge are installed with bolts.

[0004] However, since the shock absorber is subjected to stress for a long time, it is easy to cause wear and damage to the shock absorber, and the shock absorber needs to be replaced regularly. The bolts of the bolt-connected shock absorber need to be disassembled and assembled during the replacement process, which makes the replacement of the shock absorber more cumbersome.

[0031] Further, in the above technical solution, a connecting plate 14 is provided between the two support bars 13, the top of the connecting plate 14 is fitted with the bottom of the support bar 13, the connecting plate 14 is connected to the support bar 13 by an insertion shaft 15, a rotating block 20 is provided at the bottom of the connecting plate 14, a positioning block 23 is provided in the middle just above the cement base 1, the internal rotation of the positioning block 23 is connected to a hydraulic shock absorbing device 22, one end of the hydraulic shock absorbing device 22 is provided with a telescopic rod body 21, and the telescopic rod body 21 is slidably connected to the hydraulic shock absorbing device 22. One end of the telescopic rod body 21 is rotatably connected to the rotating block 20. After the support bar 13 is subjected to force, the support bar 13 moves downward and squeezes the rubber shock absorber 4. At the same time, the support bar 13 drives the telescopic rod body 21 to slide on the inner wall of the hydraulic shock absorber 22 through the connecting plate 14, so that the telescopic rod body 21 squeezes the hydraulic oil in the hydraulic shock absorber 22, slowing down the shaking amplitude of the support bar 13. At the same time, the squeezing amplitude of the rubber shock absorber 4 by the support bar 13 can be reduced, thereby avoiding the rubber inside the rubber shock absorber 4 from breaking after the rubber shock absorber 4 is subjected to a large force.

[0032] Furthermore, in the above technical solution, an auxiliary bar 16 is provided at one end of the support bar 13, and auxiliary grooves 19 are opened on both sides of the interior of the auxiliary bar 16. The auxiliary grooves 19 are arranged directly above the plug block 12. The two auxiliary blocks 17 in one support bar 13 are installed into the interior of the two second slots 7 on one side of the top of the cement base 1, and the auxiliary blocks 17 are fixed to the interior of the second slots 7 by fixing bolts 18, so as to realize a stable connection between the shock-absorbing base and the bridge.

[0033] Furthermore, in the above technical solution, an auxiliary block 17 is provided on one side of the auxiliary strip 16, and the outer wall of the auxiliary block 17 is fitted with the inner wall of the second slot 7, and the auxiliary block 17 is connected to the second slot 7 by a fixing bolt 18, and the number of the rubber shock absorbers 4 is set to four, and the four rubber shock absorbers 4 are arranged between the mounting block 6 and the first slot 3. When it is necessary to lift the support strip 13 to replace the rubber shock absorber 4, the hydraulic telescopic rod 9 is started, and the hydraulic telescopic rod 9 drives the lifting plate 10 to move upward, and then the lifting plate 10 drives the lifting shaft 11 to move upward, and the lifting shaft 11 drives the plug block 12 to move upward, so that the plug block 12 is fitted with the auxiliary groove 19 and pushes the support strip 13 to move upward, so that the mounting block 6 is separated from the top of the rubber shock absorber 4, so that the rubber shock absorber 4 can be removed from the inside of the first slot 3 for replacement.

[0034] How this utility works:

[0035] Refer to the instruction manual Figure 1-4 First, a bridge plate is installed on the top of the support bar 13 for pedestrians to walk. When the support bar 13 is stressed, the support bar 13 drives the telescopic rod body 21 to rotate through the connecting plate 14, and the telescopic rod body 21 slides on the inner wall of the hydraulic shock absorbing device 22 and squeezes the hydraulic oil in the hydraulic shock absorbing device 22. At the same time, the support bar 13 moves downward to squeeze the rubber shock absorber 4 through the mounting block 6 to reduce the shock of the bridge.

[0036] When the rubber shock absorber 4 is damaged and needs to be replaced, the hydraulic telescopic rod 9 is started, and the hydraulic telescopic rod 9 pushes the lifting plate 10 to move upward. The lifting plate 10 drives the plug block 12 to move upward through the lifting shaft 11, so that the plug block 12 enters the auxiliary groove 19 and pushes the support bar 13 to move upward. Then the support bar 13 drives the mounting block 6 to detach from the top of the rubber shock absorber 4, and then the rubber shock absorber 4 can be taken out from the inside of the first slot 3 for replacement.

[0037] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
