Description

Technical Field

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

[0002] Bridge bearings are key structural components used in bridge construction to connect the beams and piers. Their function is to support the structure and adapt to the movement of the structure caused by thermal expansion and contraction, load, vibration and other factors through the deformation or movement of the bearing components themselves. Due to the long operating time of bridges, there are problems such as aging and disrepair of the bearings, which cause them to fail to meet the quality requirements and need to be replaced.

[0003] Currently, bridge jacking is carried out using multiple jacks. The lifting height of the jacks is limited, so support blocks are usually used to increase the lifting height. Sometimes multiple support blocks are used in combination. However, there is no targeted quick splicing structure between the multiple support blocks, which can easily lead to unstable connections and low safety during use. There is an urgent need to design a bridge bearing jacking synchronous replacement device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a bridge bearing lifting and synchronous replacement device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A bridge bearing lifting and synchronous replacement device includes an installation plate with a groove on one side corresponding to a bridge beam. Two jacks are mounted on the top of the installation plate, located on opposite sides of the groove. Support columns are positioned on top of the jacks. Multiple installation holes are formed on the top of the installation plate. Four slots are arranged in a rectangular array on the top of the installation plate. Support plates are rotatably fitted within each slot. A pad is rotatably fitted at one end of the support plate. A fixing plate is rotatably fitted on one side of the support plate. A limit mechanism is provided between one end of the fixing plate and the slot. Rotary discs are rotatably fitted at the top of both the jacks and the support columns. A locking block is provided at the bottom of the support column. A locking groove is formed on the top of the rotating disc. A guide groove corresponding to the locking groove is formed on one side of the top of the jack.

[0006] Furthermore, the top of the mounting plate is provided with an arc-shaped groove, which corresponds to the groove. An arc-shaped rod is slidably fitted inside the arc-shaped groove, and a laser level is installed on the top of the arc-shaped rod.

[0007] Furthermore, a plurality of connecting blocks are provided on one side of the support plate, and a positioning pin is provided at one end of the fixing plate. The fixing plate is rotatably engaged with the plurality of connecting blocks through the positioning pin. The limiting mechanism includes a plurality of limiting holes provided between the mounting plate and the slot, and a limiting bolt provided at the other end of the fixing plate. The limiting bolt corresponds to the plurality of limiting holes.

[0008] Furthermore, the top of the pad is provided with multiple anti-slip pads, and the top of the support column is provided with a rubber sleeve.

[0009] Furthermore, the bottom of the mounting plate is provided with two support frames, which are L-shaped. The top of the support frame is provided with multiple connecting holes, and mounting bolts are provided between the mounting holes and the connecting holes. Multiple positioning holes are provided on one side of the support frame for connecting bridge beams and columns. Multiple reinforcing blocks are provided inside the support frame.

[0010] Furthermore, the jack is provided with a base plate at its top, and a plurality of fixing bolts are provided between the base plate and the mounting plate.

[0011] In the above technical solution, the bridge bearing jacking and synchronous replacement device provided by this utility model has the following advantages: The locking blocks at the bottom of the support column allow them to enter the slot at the top of the rotating disk along the guide groove, causing the support column to rotate and thus driving the rotating disk to rotate. This allows for quick locking and facilitates the rapid assembly of multiple rotating disks, reducing the possibility of unstable connections. The support plates allow them to rotate out of the slots, and the fixing plates are supported and fixed by the limiting mechanism. This allows the pads to provide support, and the four support plates and pads can provide temporary support, facilitating the connection and disassembly of the jack and the support column.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-4 As shown in the figure, this utility model provides a bridge bearing lifting and synchronous replacement device.

[0020] The system includes a mounting plate 1, with a groove 2 on one side corresponding to a bridge beam column. Two jacks 3 are mounted on the top of the mounting plate 1, located on either side of the groove 2. A support column 4 is mounted on the top of each jack 3. Multiple mounting holes 5 are provided on the top of the mounting plate 1. Four slots 6 are arranged in a rectangular array on the top of the mounting plate 1. A support plate 7 is rotatably fitted inside each slot 6. A pad 8 is rotatably fitted at one end of the support plate 7. A fixing plate 9 is rotatably fitted on one side of the support plate 7. A limit mechanism is provided between one end of the fixing plate 9 and the slot 6. A rotating disk 10 is rotatably fitted on the top of both the jacks 3 and the support column 4. A locking block 11 is provided at the bottom of the support column 4. A locking groove 12 is provided on the top of the rotating disk 10. A guide groove 13 corresponding to the locking groove 12 is provided on one side of the top of the jacks 3.

[0021] Reference Figure 2 In this embodiment, the top of the mounting plate 1 is provided with an arc-shaped groove 15, which corresponds to the groove 2. An arc-shaped rod 16 is slidably fitted inside the arc-shaped groove 15, and a laser level 17 is mounted on the top of the arc-shaped rod 16. The arc-shaped rod 16 allows the rod to move along the arc-shaped groove 15 and rotate on the top of the mounting plate 1, enabling the laser level 17 to move along with the rod and measure the inclination of the bridge support.

[0022] Reference Figure 2 In this embodiment, a plurality of connecting blocks 18 are provided on one side of the support plate 7, and a positioning pin 19 is provided at one end of the fixing plate 9. The fixing plate 9 is rotatably engaged with the plurality of connecting blocks 18 through the positioning pin 19. The limiting mechanism includes a plurality of limiting holes 20 provided between the mounting plate 1 and the slot 6, and a limiting bolt 21 provided at the other end of the fixing plate 9. The limiting bolt 21 corresponds to the plurality of limiting holes 20. By using the positioning pin 19, the connection between one end of the fixing plate 9 and one side of the support plate 7 can be released by pulling out the positioning pin 19, adjusting the fixing plate 9 to the required connecting block 18, and inserting the positioning pin 19 for fixation. While changing the support position of the fixing plate 9, the support height of the support plate 7 is also changed. The support position of the fixing plate 9 can also be changed by inserting the limiting bolt 21 into different limiting holes 20.

[0023] Reference Figure 2 In this embodiment, the top of the pad 8 is provided with multiple anti-slip pads 22, and the top of the support column 4 is provided with a rubber sleeve 14. The anti-slip pads 22 provide a certain anti-slip effect when the pad 8 is supported, and the rubber sleeve 14 can protect the top of the support column 4, reduce the wear of the rotating disk 10, and can be put on the corresponding support column 4 as needed.

[0024] Reference Figure 3 In this embodiment, the mounting plate 1 has two support frames 23 at its bottom. The support frames 23 are L-shaped, and multiple connecting holes 24 are provided on the top of the support frames 23. Mounting bolts 25 are provided between the mounting holes 5 and the connecting holes 24. Multiple positioning holes 26 are provided on one side of the support frame 23. The positioning holes 26 are used to connect to the bridge beams and columns. Multiple reinforcing blocks 27 are provided inside the support frame 23. With the support frames 23, when there is no mounting position for the mounting plate 1, the support frames 23 can be installed at the bottom of the mounting plate 1, so that the support frames 23 are connected to the bridge beams and columns, and the support frames 23 support and fix the mounting plate 1.

[0025] Reference Figure 4 In this embodiment, the jack 3 has a base plate 28 on its top, and a plurality of fixing bolts 29 are provided between the base plate 28 and the mounting plate 1. Through the base plate 28, the fixing bolts 29 can be used to connect the base plate 28 and the mounting plate 1, and the jack 3 can be installed on the top of the mounting plate 1. The jack 3 can be disassembled when needed.

[0026] Working principle: In use, first move the mounting plate 1 to the bridge, aligning the groove 2 with the bridge beam. Then push the mounting plate 1, allowing the bridge beam to enter the groove 2. Next, install and fix the mounting plate 1. Activating the jack 3 will lift the bridge beam. If further height is needed after jack 3 has lifted the beam, rotate the four support plates 7, allowing the pads 8 of the support plates 7 to align with the bottom of the beam. Then rotate the fixing plate 9, fixing it with the limiting mechanism. This allows the fixing plate 9 to support and fix the support plates 7. When the jack 3 is retracted, the four support plates 7 will provide temporary support for the bridge. Then, the support column 4 is taken out, and the locking block 11 at the bottom of the support column 4 is aligned with the guide groove 13. The support column 4 is pushed so that the locking block 11 enters the locking groove 12 along the guide groove 13. Then, the support column 4 is rotated to drive the locking block 11 and the rotating disk 10 to rotate, locking the locking block 11 and completing the splicing of the jack 3 and the support column 4. Then, the jack 3 can continue to drive the support column 4 to lift. Repeating the above steps can continuously stack multiple support columns 4 for use.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
