Description

Technical Field

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

[0002] Bridge reinforcement is an engineering measure to strengthen and repair existing bridge structures, aiming to improve their load-bearing capacity, extend their service life, and ensure safety. With increasing traffic volume and aging bridges, the original design may no longer meet modern traffic demands or be damaged by environmental and natural disasters. Reinforcement methods typically include adding supporting structures, using high-strength materials, applying braking devices, and improving the bridge's corrosion protection.

[0003] However, traditional bridge reinforcement lifting devices have a relatively complex structure and are cumbersome to use, making them inconvenient to use and difficult to store and transport. This results in poor maintenance and portability of the bridge reinforcement lifting device.

[0004] Therefore, those skilled in the art have provided a jacking device for bridge reinforcement to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a jacking device for bridge reinforcement. This bridge reinforcement jacking device consists of a support base, a jacking plate, a lifting mechanism, and a positioning mechanism. Users can operate the jacking device simply by adjusting the lifting mechanism with tools. The positioning mechanism is used to lock and fix the adjusted device in place. The simple structure facilitates operation and use, thereby reducing the possibility of damage to the device and improving its service life and durability.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A lifting device for bridge reinforcement includes a support base, a lifting plate slidably connected to the upper end of the inner wall of the support base, a lifting mechanism provided on the inner bottom surface of the support base, the lifting mechanism including a lower connecting groove, an upper connecting groove and a bidirectional threaded rod, a lower rotating shaft rotatably connected to the front and rear ends of the inner walls on both sides of the lower connecting groove, a moving block threadedly engaged with the front and rear ends of the outer wall of the bidirectional threaded rod, a plurality of first support rods hinged to the middle of the upper surface of the moving block, a plurality of second support rods hinged to the middle of the lower surface of the moving block, and an upper rotating shaft rotatably connected to the front and rear ends of the inner walls on both sides of the upper connecting groove.

[0008] The outer walls on both sides of the support base are provided with positioning mechanisms. The positioning mechanisms include limiting grooves, fixing blocks and limiting sliders. A one-way threaded rod is fixedly connected to the middle of the lower surface of the fixing block. An adjusting nut and a locking nut are threadedly fitted to the outer wall of the one-way threaded rod.

[0009] The bridge reinforcement lifting device has a simple structure, which makes it easy for users to carry and store, reduces the space occupied by the device during storage, and improves the convenience of maintenance and repair, thereby further reducing the possibility of damage to the device.

[0010] Furthermore, an anti-slip pad is fixedly connected to the middle of the upper surface of the lifting plate;

[0011] By using the above technical solution, the possibility of the device shifting during installation is reduced by setting anti-slip pads, thereby improving the device's stability in the required position.

[0012] Furthermore, a partition plate is fixedly connected to the center of the outer wall of the bidirectional threaded rod, and a stop block is fixedly connected to the outer wall of both the front and rear ends of the bidirectional threaded rod;

[0013] The above technical solution restricts and limits the position of the moving block by setting up partitions and blocks.

[0014] Furthermore, a rotating block is fixedly connected to the middle of the outer wall of the stop block on the side away from the bidirectional threaded rod;

[0015] The above technical solution allows users to adjust the bidirectional threaded rod using a wrench by setting a rotating block.

[0016] Furthermore, a first connecting groove is provided at the end of the first support rod away from the moving block, and the first connecting groove is fixedly connected to the lower rotating shaft;

[0017] The above technical solution enables the lifting mechanism to connect with the support base.

[0018] Furthermore, a second connecting groove is provided at the end of the second support rod away from the moving block, and the second connecting groove is fixedly connected to the upper rotating shaft;

[0019] The above technical solution enables the lifting mechanism to connect with the lifting plate.

[0020] Furthermore, the lower connecting groove is located in the middle of the inner bottom surface of the support base, and the upper connecting groove is located in the middle of the inner top surface of the lifting plate.

[0021] The above technical solution enables the lifting mechanism to adjust the position between the support base and the lifting plate.

[0022] Furthermore, the limiting slide grooves are respectively opened at the front end and rear end of the outer walls on both sides of the support base, the fixing blocks are respectively fixedly connected to the front and rear ends of the upper part of the outer walls on both sides of the support base, the limiting sliders are respectively fixedly connected to the front end and rear end of the lower part of the outer walls on both sides of the lifting plate, and the limiting slide grooves and the limiting sliders are slidably connected.

[0023] The above technical solution enables the limiting slider to move on the outer wall of the one-way threaded rod when the lifting plate rises. This allows the limiting slider to be locked in position on the one-way threaded rod by adjusting the adjusting nut and locking nut, thus locking the adjusted position of the lifting plate.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a jacking device for bridge reinforcement. Compared with most traditional bridge reinforcement jacking devices, this bridge reinforcement jacking device consists of a support base, a jacking plate, a lifting mechanism, and a positioning mechanism. Users only need to adjust the lifting mechanism with tools to operate and use the jacking device. The positioning mechanism is used to lock and fix the adjusted device in position. The simple structure makes it easy for users to operate and use, thereby reducing the possibility of damage to the device and improving its service life and durability.

[0026] 2. The jacking device for bridge reinforcement proposed in this utility model has a simple structure compared with most traditional bridge reinforcement jacking devices. This makes it easier for users to carry and store, reduces the space occupied by the device during storage, and improves the convenience of maintenance and repair, thereby further reducing the possibility of damage to the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1-5 One embodiment provided by this utility model:

[0039] A lifting device for bridge reinforcement includes a support base 1, a lifting plate 2 slidably connected to the upper end of the inner wall of the support base 1, and a lifting mechanism 3 provided on the inner bottom surface of the support base 1. The lifting mechanism 3 includes a lower connecting groove 301, an upper connecting groove 3012, and a bidirectional threaded rod 303. The front and rear ends of the inner walls on both sides of the lower connecting groove 301 are rotatably connected to a lower rotating shaft 302. The front and rear ends of the outer wall of the bidirectional threaded rod 303 are threadedly fitted with a moving block 307. A plurality of first support rods 308 are hingedly connected to the middle of the upper surface of the moving block 307, and a plurality of second support rods 3010 are hingedly connected to the middle of the lower surface of the moving block 307. The front and rear ends of the inner walls on both sides of the upper connecting groove 3012 are rotatably connected to an upper rotating shaft 3013.

[0040] Positioning mechanisms 4 are provided on the outer walls of both sides of the support base 1. The positioning mechanism 4 includes a limiting slide 401, a fixing block 402, and a limiting slider 406. A one-way threaded rod 403 is fixedly connected to the middle of the lower surface of the fixing block 402. An adjusting nut 404 and a locking nut 405 are threadedly fitted on the outer wall of the one-way threaded rod 403. The bridge reinforcement lifting device consists of a support base 1, a lifting plate 2, a lifting mechanism 3, and a positioning mechanism 4. Users only need to adjust the lifting mechanism 3 with tools to operate the lifting device. The positioning mechanism 4 is used to lock and fix the position of the adjusted device. The simple structure makes it easy for users to operate and use the device, thereby reducing the possibility of damage to the device and improving its service life and durability.

[0041] An anti-slip pad 5 is fixedly connected to the center of the upper surface of the lifting plate 2. The anti-slip pad 5 reduces the possibility of misalignment during installation, thus improving the device's stability in the desired position. A partition 304 is fixedly connected to the center of the outer wall of the bidirectional threaded rod 303. Stops 305 are fixedly connected to the outer walls of both the front and rear ends of the bidirectional threaded rod 303. The partition 304 and stops 305 limit the position of the moving block 307. A rotating block 306 is fixedly connected to the center of the outer wall of the stop 305 on the side away from the bidirectional threaded rod 303. The rotating block 306 allows the user to adjust the bidirectional threaded rod 303 using a wrench. The first support rod 308 has a first connecting groove 309 at the end away from the moving block 307. The first connecting groove 309 is fixedly connected to the lower rotating shaft 302, so that the lifting mechanism 3 can be connected to the support base 1. The second support rod 3010 has a second connecting groove 3011 at the end away from the moving block 307. The second connecting groove 3011 is fixedly connected to the upper rotating shaft 3013, so that the lifting mechanism 3 can be connected to the lifting plate 2. The lower connecting groove 301 is opened in the middle of the inner bottom surface of the support base 1, and the upper connecting groove 3012 is opened in the middle of the inner top surface of the lifting plate 2, so that the lifting mechanism 3 can adjust the position between the support base 1 and the lifting plate 2.

[0042] Limiting grooves 401 are respectively opened at the front and rear ends of the outer walls on both sides of the support base 1. Fixing blocks 402 are respectively fixedly connected to the front and rear ends of the upper part of the outer walls on both sides of the support base 1. Limiting sliders 406 are respectively fixedly connected to the front and rear ends of the lower part of the outer walls on both sides of the lifting plate 2. The limiting grooves 401 and the limiting sliders 406 are slidably connected, so that when the lifting plate 2 rises, the limiting sliders 406 move on the outer wall of the one-way threaded rod 403. Then, by adjusting the adjusting nut 404 and the locking nut 405, the position of the limiting sliders 406 on the one-way threaded rod 403 can be limited and locked, so that the adjusted position of the lifting plate 2 can be locked and limited.

[0043] Working principle: First, place the device in the required position, with the support base 1 at the bottom. The lifting plate 2 and anti-slip pad 5 contact the bridge reinforcement object to be lifted under the action of the lifting mechanism 3. When using the lifting mechanism 3, the double-threaded rod 303 is rotated with a wrench, thereby adjusting the moving block 307. This allows the first support rod 308 and the second support rod 3010 to adjust the position between the lifting plate 2 and the support base 1, and then contact the bridge reinforcement object to be lifted. After the adjustment is completed, the positions of each adjusting nut 404 and locking nut 405 are adjusted. Finally, the bridge reinforcement object can be supported and lifted, reducing the possibility of the object sinking.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
