Description

Technical Field

[0001] This utility model relates to the field of bridge bearing replacement technology, and in particular to a bridge bearing replacement device. Background Technology

[0002] Bridge bearings are crucial structural components connecting the superstructure and substructure of a bridge. Located between the bridge and the piers, they reliably transfer the loads, deformations, displacements, and rotations borne by the superstructure to the substructure, serving as a vital force transmission device. To ensure bridge safety, bridge bearings require periodic replacement. This necessitates the use of jacks to lift the superstructure, thereby replacing the bridge bearings connecting the superstructure and substructure.

[0003] In the current use of jacks, some jacks have a small bottom support area, which leads to insufficient stability when bearing large loads. When they are extended or moved, they may deviate or sway. The deviation or swaying of the jacks will cause the lifting position of the bridge superstructure to be inaccurate. Construction workers need to spend more time and effort to adjust and correct, which will prolong the construction period and increase the construction cost. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bridge bearing replacement device to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bridge bearing replacement device includes a base, a jack fixedly mounted on the top of the base, a support plate fixedly mounted on the output end of the jack, a guide assembly on the top of the base and connected to the support plate, a drive assembly on the front side of the base, and screws on both the left and right sides of the base via the drive assembly. A frame is rotatably connected to the surface of the screw, the frame is fixedly connected to the base, a movable block is threadedly connected to the surface of the screw and slidably connected to the frame, an installation assembly is provided on the surface of the movable block, a clamping plate is provided on the surface of the movable block via the installation assembly, and an anti-slip pad is fixedly mounted on the surface of the clamping plate.

[0006] Preferably, the guide assembly includes a guide sleeve fixedly installed on the top of the base, a guide post slidably connected inside the guide sleeve, and the guide post being fixedly connected to the support plate.

[0007] Preferably, the drive assembly includes a dual-axis motor fixedly mounted on the front side of the base, a first bevel gear fixedly mounted on the output end of the dual-axis motor, a second bevel gear meshing on the surface of the first bevel gear, and the second bevel gear being fixedly connected to a screw.

[0008] Preferably, the mounting assembly includes a movable plate fixedly mounted on the surface of the movable block, the top of the movable plate having a slot, a plug being inserted into the slot, the plug being fixedly connected to a clamping plate, and a bolt being threadedly connected inside the plug, the bolt being threadedly connected to the movable plate.

[0009] Preferably, the screw is a bidirectional threaded screw, and the screw is made of stainless steel.

[0010] Preferably, there are multiple guide posts, and the multiple guide posts are symmetrically distributed.

[0011] Preferably, the insert has a T-shaped structure, and the slot is adapted to the insert.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This bridge bearing replacement device places the device in a suitable position on the pier, and the drive component causes the screw to rotate, causing the moving blocks to move closer together along the frame, causing the installation components to move closer together, and causing the clamping plate and anti-slip pad to move closer together, so that the anti-slip pad is in close contact with the front and rear sides of the pier, thus fixing the device on the pier. Then, the jacks are used to move the support plate upward along the guide component to lift the bridge, and then the bridge bearing between the bridge and the pier can be replaced. The device is fixed to the pier before the bridge is lifted, which effectively prevents the jack from shifting or shaking during the lifting process, and avoids the problem of inaccurate lifting position caused by the jack shifting or shaking. Construction personnel do not need to spend extra time and energy to adjust and correct, which greatly improves the construction speed and shortens the construction cycle.

[0016] Reference Figure 1-5 A bridge bearing replacement device includes a base 1, a jack 2 fixedly mounted on the top of the base 1, a support plate 3 fixedly mounted on the output end of the jack 2, a guide assembly on the top of the base 1 connected to the support plate 3, a drive assembly on the front of the base 1, and screws 9 on both sides of the base 1 via the drive assembly. The screws 9 are bidirectional threaded rods made of stainless steel to provide higher structural strength and durability. The drive assembly includes a dual-axis motor 6 fixedly mounted on the front of the base 1, a first bevel gear 7 fixedly mounted on the output end of the dual-axis motor 6, a second bevel gear 8 meshing with the surface of the first bevel gear 7, and a fixed connection between the second bevel gear 8 and the screws 9. The drive assembly provides driving force for the rotation of the screws 9. A frame 10 is rotatably connected to the surface of the screws 9, the frame 10 is fixedly connected to the base 1, and a moving block 11 is threadedly connected to the surface of the screws 9, slidingly connected to the frame 10. The surface of the moving block 11 is provided with mounting... The component, the moving block 11, has a clamping plate 16 installed on its surface via an installation component. An anti-slip pad 17 is fixedly installed on the surface of the clamping plate 16. This bridge bearing replacement device is placed at a suitable position on the pier. The drive component rotates the screw 9, causing the moving blocks 11 to move closer together along the frame 10. This brings the installation components closer together, and the clamping plate 16 and anti-slip pad 17 together, ensuring the anti-slip pad 17 is in close contact with both the front and rear sides of the pier, thus fixing the device to the pier. Then, the jack 2 moves the support plate 3 upward along the guide component, lifting the bridge. The bridge bearing between the bridge and the pier can then be replaced. This fixes the device to the pier before lifting the bridge, effectively preventing possible displacement or swaying of the jack 2 during the lifting process. It avoids inaccurate lifting positions caused by jack 2 displacement or swaying, eliminating the need for construction personnel to spend extra time and effort on adjustments and corrections, greatly improving construction speed and shortening the construction cycle.

[0017] Specifically, the guide assembly includes a guide sleeve 4 fixedly installed on the top of the base 1. Guide posts 5 are slidably connected inside the guide sleeve 4. There are multiple guide posts 5, and the multiple guide posts 5 are symmetrically distributed. The guide posts 5 are fixedly connected to the support plate 3. By setting the guide assembly, it is convenient to guide the movement of the support plate 3, so that the support plate 3 can move more stably and avoid the phenomenon of deviation when the support plate 3 moves.

[0018] Specifically, the installation components include a movable plate 12 fixedly mounted on the surface of the movable block 11. The top of the movable plate 12 has a slot 13, and a plug 14 is inserted into the slot 13. The plug 14 has a T-shaped structure, and the slot 13 and plug 14 are compatible. Through the cooperation of the plug 14 and slot 13, the subsequent clamping plate 16 and anti-slip pad 17 can be more securely fixed to the pier, thus facilitating more stable use of the device. The plug 14 is fixedly connected to the clamping plate 16. 4. The internal threaded connection is a bolt 15, which is threaded to the movable plate 12. Remove the bolt 15 and pull out the insert 14 from the top of the slot 13 to complete the disassembly of the clamping plate 16 and the anti-slip pad 17. Then, they can be replaced. Insert the insert 14 on the new clamping plate 16 and the anti-slip pad 17 into the slot 13, and then install the bolt 15 into the movable plate 12 and the insert 14 to fix the insert 14. This completes the fixation of the clamping plate 16 and the anti-slip pad 17.

[0019] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.
