Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, and more specifically to an anchoring device for a bridge support. Background Art

[0002] Bridge bearings are important structural components that connect the superstructure and substructure of a bridge. They are located between the bridge and the pad stone. They can reliably transfer the load and deformation (displacement and rotation) borne by the superstructure of the bridge to the substructure of the bridge. They are important force transmission devices of the bridge. There are two types of bearings: fixed bearings and movable bearings. Commonly used bearing forms in bridge engineering include: asphalt felt or flat bearings, plate rubber bearings, spherical bearings, steel bearings and special bearings.

[0003] The current bridge bearing anchoring device directly uses a preset expansion tube or a fixed tube, and then fixes the bridge bearing between the pier and the bridge through bolts. When the bridge bearing is aged and needs to be replaced, the bridge bearing needs to be removed and then replaced with a new bearing. When installing the new bearing, bolt fixation is also required, which makes the installation more troublesome. When the bridge deck applies force to the bearing, the pressure load borne by the bearing will also be borne by the anchor. The bolt is a threaded component, and its thread is easily deformed due to long-term pressure, making it difficult to unscrew the anchor, thereby increasing the burden of maintenance work. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide an anchoring device for a bridge bearing, which improves the convenience of fixing, installing and disassembling the bearing body of the bridge and improves the overall structural reliability.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] An anchoring device for a bridge support, comprising a support body, a sleeve installed on the support body, a rotating rod movably connected to the inner side of the sleeve, a screw rod connected to the lower end of the rotating rod, a slidable slider connected to the screw rod through a thread, a sliding groove is provided on the inner wall of the sleeve, and the slider slidably cooperates with the sliding groove; a connecting rod is rotatably connected to one side of the slider, a through groove is also provided on the sleeve, a limit block is provided in the through groove, and the limit block is rotatably connected to the connecting rod; the sleeve is connected to the pier of the bridge, and is anchored to the pier of the bridge by using the limit block.

[0007] Furthermore, a mounting hole is provided on the support body, a bottom plate is placed on the upper side of the mounting hole, the bottom plate is fixedly connected to the sleeve, and the sleeve passes downward through the mounting hole.

[0008] Furthermore, a bracket is fixed on one side of the base plate, and a tooth groove is also provided on one side of the base plate. A positioning piece is fixed on the outer side of the rotating rod, and the positioning piece has positioning teeth that can engage with the tooth groove; a spring is provided between the bracket and the positioning piece.

[0009] Furthermore, the upper end of the rotating rod passes through the bracket, and the rotating rod and the bracket are movably matched, the spring is sleeved on the rotating rod, and the lower end of the rotating rod extends to the inside of the sleeve.

[0010] The spring is used to apply elastic force to the positioning member, so that the positioning teeth of the positioning member are meshed with the tooth grooves of the bottom plate, thereby fixing the sleeve and the rotating rod.

[0011] Furthermore, a turntable is fixed to the upper end of the rotating rod, and the operation of the rotating rod can be facilitated by using the turntable.

[0012] Furthermore, a fixing block is fixed on the inner side of the sleeve, and the screw rod passes through the fixing block and is rotationally connected to the fixing block, so that the screw rod can rotate relative to the fixing block and the sleeve.

[0013] Furthermore, the pier is located on one side of the support body, and a connecting slot is provided in the pier. The connecting slot is an inverted T-shaped structure with a small-sized portion and a large-sized portion. The sleeve is connected to the connecting slot, and the limit block can be anchored in the large-sized portion of the connecting slot, thereby realizing the anchoring of the sleeve in the pier, and further realizing the anchoring between the support body and the pier.

[0014] Furthermore, a plurality of the limit blocks are provided, and the plurality of limit blocks are evenly distributed relative to the sleeve.

[0015] The beneficial effects of the utility model are:

[0016] The utility model drives the screw rod to rotate by rotating the rotating rod, and the screw rod can drive the slider threadedly connected thereto to slide up and down. Under the action of the connecting rod, the limit block can be driven to rotate and adjust, so that when the limit block is opened, it can be anchored at the lower end of the pier, thereby realizing the fixing of the sleeve, making it easy to fix the support body. Similarly, when the limit block is retracted, the fixing of the sleeve can be released, making it easy to fix, install and disassemble the support body.

[0017] By anchoring the support body and the bridge pier through sleeves and limit blocks, the overall structural performance can be improved. Compared with the structure using threaded components for anchoring in the prior art, it is less prone to damage and avoids the pressure load borne by the support when the bridge deck applies force to the support also being borne by the anchoring structure, thereby avoiding deformation of the anchoring structure.

[0027] like Figures 1 to 3 A preferred embodiment of an anchoring device for a bridge bearing is shown, which includes a bearing body 1 and a sleeve 4. The bearing body 1 is provided with a mounting hole 2. A bottom plate 3 is placed on the upper side of the mounting hole 2. The bottom plate 3 is fixedly connected to the sleeve 4, and the sleeve 4 passes downward through the mounting hole 2. The sleeve 4 can be connected to the bearing body 1 through the bottom plate 3 and the mounting hole 2. A fixing block 11 is fixed to the inner side of the sleeve 4; a rotating rod 5 is passed through the sleeve 4, and a screw rod 12 is connected to the lower end of the rotating rod 5. The rotating rod 5 and the screw rod 12 are relatively fixed in the circumferential direction; the screw rod 12 passes through the fixing block 11 and is rotationally connected to the fixing block 11. The screw rod 12 is connected to a slidable slider 14 through a threaded connection, and a slide groove 13 is provided on the inner wall of the sleeve 4, and the slider 14 slidably cooperates with the slide groove 13; a connecting rod 15 is rotatably connected to one side of the slider 14, and a through groove 16 is provided at the lower end of the sleeve 4, and a limit block 17 is provided in the through groove 16, and the limit block 17 is rotatably connected to the connecting rod 15; the sleeve 4 is connected to the pier 18 of the bridge, and is anchored to the pier 18 of the bridge by using the limit block 17.

[0028] Specifically, the pier 18 is located on one side of the support body 1, and a connecting slot 19 is provided in the pier 18. The connecting slot 19 is an inverted T-shaped structure with a small-sized portion and a large-sized portion. The sleeve 4 is connected to the connecting slot 19, and the limit block 17 can be anchored in the large-sized portion of the connecting slot 19.

[0029] There are multiple limit blocks 17 , and correspondingly, a plurality of through slots 16 are formed at the lower end of the sleeve 4 . The multiple limit blocks 17 are evenly distributed relative to the sleeve 4 .

[0030] The rotation of the rotating rod 5 can drive the rotation of the screw rod 12, and the screw rod 12 can drive the slider 14 threadedly connected thereto to slide and adjust in the slide groove 13. Under the action of the connecting rod 15, the rotation adjustment of the limit block 17 can be driven, so that when the limit block 17 is opened, it can be restricted to the lower end of the connecting slot 19 (in the large-size part of the connecting slot), thereby realizing the fixation of the sleeve 4, making it easy to fix the support body 1. Similarly, when the limit block 17 is retracted, the fixation of the sleeve 4 can be released, making it easy to fix the support body 1.

[0031] A bracket 8 is fixed on the upper side of the base plate 3, and a plurality of tooth grooves 6 are also provided on the upper side of the base plate 3. A positioning member 7 located above the base plate 3 is fixed on the outer side of the rotating rod 5. The positioning member 7 has a plurality of positioning teeth corresponding to the tooth grooves 6, and the positioning teeth can engage with the tooth grooves 6. A spring 9 is provided between the bracket 8 and the positioning member 7.

[0032] The upper end of the rotating rod 5 passes through the bracket 8 upward, and the rotating rod 5 and the bracket 8 are movably matched. The spring 9 is sleeved on the rotating rod 5, and the spring 9 can exert elastic force as the rotating rod 5 moves up and down; the lower end of the rotating rod 5 extends to the inside of the sleeve 4.

[0033] In addition, a rotating disk 10 is fixed to the upper end of the rotating rod 5 .

[0034] The spring 9 is provided so that the spring 9 can apply elastic force between the positioning member 7 and the bracket 8 to move the positioning member downward until the positioning tooth is engaged with the tooth groove 6, thereby limiting the circumferential movement of the rotating rod 5.

[0035] The working principle and use process of the utility model are as follows: when in use, the mounting hole 2 of the support body 1 is aligned with the connecting slot hole 19 of the pier 18, and the sleeve 4 is inserted into the mounting hole 2 and the connecting slot hole 19. By pulling the rotating rod 5 upward, the spring 9 is compressed, and the positioning teeth of the positioning member 7 are separated from the tooth groove 6, and then the turntable 10 is rotated to make the turntable 10 drive the rotating rod 5 to rotate. The rotating rod 5 can drive the screw rod 12 to rotate, so that the screw rod 12 drives the slider 14 threadedly connected thereto to slide and adjust in the slide groove 13. Under the action of the connecting rod 15, the slider 14 can drive the limit block 17 to rotate in the through groove 16 of the sleeve, so that the limit block 17 opens to the outside of the sleeve 4 and is limited inside the large size part of the lower end of the connecting slot hole 19, so that the sleeve 4 is limited in the connecting slot hole of the pier 18, and the support body 1 can be fixed on the pier 18. When the turntable 10 is released, the positioning teeth mesh with the tooth grooves 6 under the action of the spring 9, so that the circumferential movement of the turntable 10 can be limited, and the turntable 10 can be prevented from loosening. Similarly, when the support body 1 needs to be disassembled, the limit block 17 is controlled to rotate so that the limit block 17 is retracted and separated from the lower end of the connecting slot 19, and the sleeve 4 can be taken out to realize the disassembly of the support body 1.
