Description

Technical Field

[0001] This utility model relates to the field of bridge expansion joint technology, and in particular to a bridge expansion joint installation and adjustment tool. Background Technology

[0002] Expansion joints are installed within the gaps between bridge beams, primarily to meet requirements for expansion and contraction, waterproofing, and preventing rainwater corrosion of the beams. The quality of bridge expansion joint construction directly affects the bridge's service life and function. If the expansion joints are not precisely positioned or securely installed in the two directions parallel and perpendicular to the bridge axis, vehicles will experience bouncing and noise, directly impacting road surface smoothness and comfort. Once an expansion joint is damaged, replacement is difficult and extremely expensive. Therefore, in addition to ensuring the expansion joints meet technical standards, correct construction and installation are crucial for their successful application. However, currently, specialized tools for adjusting and installing expansion joints are lacking.

[0003] For example, Chinese Patent Publication No. CN210086066U describes a bridge expansion joint installation and adjustment tool, which includes a solar panel, a fixing frame, a base, and a mounting base. The top of the fixing frame is equipped with a solar panel, and a battery is installed on the top of the fixing frame on one side of the solar panel. The input end of the battery is electrically connected to the output end of the solar panel through a photovoltaic controller. A control box is installed on one side of the fixing frame, and bases are installed on both sides of the bottom of the fixing frame. Reinforcing ribs are installed at the four corners of the top of the bases, and the tops of the reinforcing ribs are fixedly connected to the side walls of the fixing frame.

[0004] However, in the above solution, the device clamps and fixes the expansion joints by means of a clamp plate. Since the clamp plate has a simple structure, it can only clamp and fix one type of expansion joint and cannot be applied to different types of expansion joints. Therefore, it cannot meet people's needs and is not very convenient. Utility Model Content

[0024] Please see Figure 1-3 In this embodiment of the utility model, a bridge expansion joint installation and adjustment tool includes a top plate 1. Vertical rods 2 are fixedly connected to both ends of the bottom of the top plate 1. A base plate 5 is fixedly connected to the bottom of each of the two vertical rods 2. Two universal wheels 6 are fixedly connected to the bottom of each of the two base plates 5. All four universal wheels 6 are designed to be braked. A U-shaped plate 11 is connected to the side wall of the top plate 1 via a lifting structure. Two second sliding grooves 15 are opened at the bottom of the U-shaped plate 11. A second bidirectional threaded rod 17 is rotatably connected within each of the two second sliding grooves 15. Two threaded sections are provided on the outer side wall of each of the two second bidirectional threaded rods 17. Two L-shaped clamping plates 16 are threadedly connected to the outer side wall of each of the two second bidirectional threaded rods 17. The four L-shaped clamping plates 16 are slidably connected within the two second sliding grooves 15 and are respectively located on the two threaded sections of the side wall of each of the two second bidirectional threaded rods 17. One end of each of the two second bidirectional threaded rods 17 passes through the U-shaped plate 11 and is rotatably connected to it. A clamping structure is provided at the bottom of the U-shaped plate 11.

[0025] Please see Figure 1The lifting structure includes a motor 9, which is fixedly connected to the top side wall of the top plate 1. One end of the output shaft of the motor 9 is fixedly connected to a winding rod 8, and one end of the winding rod 8 is rotatably connected to a baffle 7, which is fixedly connected to the top side wall of the top plate 1. Two pull ropes 10 are wound around the outer side wall of the winding rod 8. Both pull ropes 10 pass through the top plate 1 and are slidably connected to the top plate 1. The bottom of both pull ropes 10 is fixedly connected to the top side wall of the U-shaped plate 11. Both pull ropes 10 are made of stainless steel. When the motor 9 is started, the output shaft of the motor 9 drives the winding rod 8 to rotate, causing the winding rod 8 to lower the two pull ropes 10, which in turn causes the pull ropes 10 to move the U-shaped plate 11 downward, thereby lowering the expansion joint into the gap of the bridge, which facilitates the installation of the expansion joint. The height of the U-shaped plate 11 can be adjusted by rotating the motor 9 in both directions.

[0026] Please see Figure 1 Two multi-stage sliding telescopic rods 3 are fixedly connected to the top of the Z-shaped plate 11. The tops of the two multi-stage sliding telescopic rods 3 are fixedly connected to the bottom side wall of the top plate 1. When the Z-shaped plate 11 moves, it will drive the two multi-stage sliding telescopic rods 3 to move. The two multi-stage sliding telescopic rods 3 can keep the Z-shaped plate 11 moving up and down stably without shaking.

[0027] Please see Figure 1-3The clamping structure includes a telescopic cylinder 4, which is fixedly connected to the bottom side wall of the U-shaped plate 11. A fixing plate 12 is fixedly connected to the extended end of the telescopic cylinder 4. The fixing plate 12 is located within the groove of the U-shaped plate 11. A first sliding groove 13 is provided at the bottom of the fixing plate 12. A first bidirectional threaded rod 18 is rotatably connected within the first sliding groove 13. The outer side wall of the first bidirectional threaded rod 18 has two threaded sections. Two V-shaped clamping plates 14 are threadedly connected to the outer side wall of the first bidirectional threaded rod 18. The two V-shaped clamping plates 14 are respectively located on the two threaded sections of the outer side wall of the first bidirectional threaded rod 18. One end of the first bidirectional threaded rod 18 passes through the fixing plate 12 and is rotatably connected to it. Rotating blocks are fixedly connected to one end of both the first bidirectional threaded rod 18 and two second bidirectional threaded rods 17. The fixing plate 12 is located at the two second bidirectional threaded rods 17. Between the sliding grooves 15, by activating the telescopic cylinder 4, the telescopic cylinder 4 drives the fixed plate 12 to move downward, so that the fixed plate 12 is lower than the four L-shaped clamps 16. Then, by turning the first bidirectional threaded rod 18, the two V-shaped clamps 14 are moved, so that the two V-shaped clamps 14 clamp the two sides of the expansion joint, thereby clamping and fixing the expansion joint. The two V-shaped clamps 14 are suitable for expansion joints of different types of comb plates, so as to facilitate clamping and fixing expansion joints of different specifications and improve the applicability of the device. The fixed plate 12 can be adjusted by the telescopic cylinder 4. When using the L-shaped clamps 16, the fixed plate 12 is located in the groove of the Z-shaped plate 11. When using the V-shaped clamps 14, the V-shaped clamps 14 are lower than the four L-shaped clamps 16, so that the V-shaped clamps 14 and the L-shaped clamps 16 will not interfere with each other during use.

[0028] The working principle of this utility model is as follows: The four universal wheels 6 facilitate movement of the device. Once the device is moved to a suitable position and the four universal wheels 6 are locked, the L-shaped clamps 16 are inserted into the gap of the expansion joint. By turning the second bidirectional threaded rod 17, the two L-shaped clamps 16 can move relative to or away from each other. Twisting the second bidirectional threaded rod 17 causes the two L-shaped clamps 16 to move away from each other, thus securing the L-shaped clamps 16 within the expansion joint. The expansion joint is clamped and fixed in the groove of the gap. The two L-shaped clamps 16 are suitable for expansion joints of the brand Zhenhai Rubber, such as GQF-Z80, F60, 160 and 240. Then, by starting the motor 9, the output shaft of the motor 9 drives the winding rod 8 to rotate, so that the winding rod 8 lowers the two pull ropes 10, and the pull ropes 10 drive the Z-shaped plate 11 to move downward, so that the expansion joint is lowered into the gap of the bridge, which facilitates the installation of the expansion joint.

[0029] By activating the telescopic cylinder 4, the fixed plate 12 moves downward, making it lower than the four L-shaped clamps 16. Then, by turning the first bidirectional threaded rod 18, the two V-shaped clamps 14 move, clamping the two V-shaped clamps 14 on both sides of the expansion joint, thereby clamping and fixing the expansion joint. The two V-shaped clamps 14 are suitable for expansion joints of different types of comb plates, thus facilitating the clamping and fixing of expansion joints of different specifications and improving the applicability of the device. The fixed plate 12 can be adjusted by the telescopic cylinder 4. When using the L-shaped clamps 16, the fixed plate 12 is located in the groove of the Z-shaped plate 11. When using the V-shaped clamps 14, the V-shaped clamps 14 are lower than the four L-shaped clamps 16, so that the V-shaped clamps 14 and L-shaped clamps 16 will not interfere with each other during use.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
