Description

Technical Field

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

[0002] Road bridge shock-absorbing supports are devices designed specifically for bridges. They are mainly used to reduce the impact on the structure under earthquakes or other external forces, thereby protecting the integrity and safety of the bridge. They can play a control role in the supporting parts of the bridge and can absorb and disperse the energy generated by external forces. The commonly used shock-absorbing method is to use multiple rubber isolation bearings.

[0003] According to the Chinese patent publication number CN220150071U, "A shock-absorbing bracket for a bridge and highway bridge", it mainly describes that the diameter of the groove at the top of the fixed column is set to be one centimeter larger than that of the lifting column, so as to ensure that the lifting column can obliquely enter the groove on the fixed column, generate resonance in the receiving plate, and perform shock absorption through the shock-absorbing spring and the lifting and lowering movement of the lifting column, so as to avoid the separation between the sliding block and the piston rod caused by non-vertical up and down shaking. When the bridge and highway vibrates, the direction and magnitude of the vibration force are different, which will cause the single shock-absorbing support to be subjected to force, thereby increasing wear and causing damage.

[0004] Therefore, a road bridge shock-absorbing support is proposed to solve the problem that when the bridge vibrates, the direction and magnitude of the vibration force are different, which will cause a single shock-absorbing support to be stressed, thereby causing increased wear and damage.

[0009] As a preferred technical solution of the utility model, a sliding ball is rotatably embedded on the stopper, and the sliding ball contacts the bottom connecting plate. By providing the sliding ball, the friction between the structures is reduced.

[0010] As a preferred technical solution of the utility model, a stabilizing rod is evenly and fixedly connected between the two opposite support rods, and the stabilizing rod is made of metal material. By providing the stabilizing rod, the stability of the support rod can be increased.

DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3The road bridge shock-absorbing bracket shown in the figure includes a bottom connecting plate 1, a buffer layer 2 and an upper connecting plate 3, the three of which constitute a shock-absorbing rubber bearing, and the shock-absorbing rubber bearing is an existing structure and is not described in detail here. A protrusion 4 is fixedly connected to the upper connecting plate 3, and a clamping strip 5 is sleeved between two adjacent protrusions 4. The clamping strip 5 is connected to the protrusion 4 to form a connecting structure. When subjected to force, multiple shock-absorbing rubber bearings can be subjected to force synchronously to reduce wear. The clamping strip 5 is an I-shaped structure. The clamping strip 5 is located in the recessed part of the I-shaped structure and is rotatably embedded with a ball 9. The ball 9 contacts the protrusion 4. The friction between the clamping strip 5 and the protrusion 4 is reduced by setting the ball 9. A hidden groove 7 is opened on the upper connecting plate 3, and a through hole 6 is opened in the hidden groove 7, and a connecting rod 8 is inserted in the through hole 6. The connecting rod 8 is movably inserted into the protrusion 4. The through hole 6 can be set to improve the limit of the clamping strip 5 on the two upper connecting plates 3.

[0018] The reinforcing plate 10 is fixedly connected to the bottom end of the clamping strip 5 , and the reinforcing plate 10 is in an inverted triangular column structure. By providing the reinforcing plate 10 , the stability of the clamping strip 5 can be increased.

[0019] Among them, the bottom connecting plate 1 is fixedly connected to the baffle ring 16, the baffle ring 16 is located on one side of the baffle block 13, the baffle block 13 is fixedly connected to the bottom end of the support rod 12, the support rod 12 is rotatably connected in the connecting frame 11 through a rotating shaft, and the two connecting frames 11 are fixedly connected to both sides of the bottom end of the reinforcing plate 10. By arranging the support rod 12 and the baffle block 13 on both sides of the bottom end of the reinforcing plate 10, support can be provided on the bottom side of the card strip 5 to improve the stability of the connection.

[0020] The bottom connecting plate 1 is in contact with the sliding ball 14 , and the sliding ball 14 is rotatably embedded in the stopper 13 . The sliding ball 14 is provided to reduce the wear between the clamping strip 5 and the protrusion 4 .

[0021] The stabilizing rod 15 is evenly and fixedly connected between two opposite supporting rods 12 . The stabilizing rod 15 is made of metal material. By providing the stabilizing rod 15 , the stability of the supporting rods 12 can be increased.

[0022] Working principle: When installing the shock-absorbing bearing, insert the clamping strip 5 between two adjacent shock-absorbing bearings and connect them through the connecting rod 8, then make the support rod 12 relatively separated, and make the sliding ball 14 of the block 13 contact the bottom connecting plate 1 and the retaining ring 16 respectively, to provide support for the clamping strip 5. At this time, when a single shock-absorbing bearing is subjected to force, the multiple shock-absorbing bearings will be buffered synchronously under the action of the clamping strip 5, thereby reducing the wear of the single shock-absorbing bearing and ensuring the uniformity of the force on the shock-absorbing structure.
