Description

Technical Field

[0001] This utility model belongs to the field of steel box girder technology, and in particular relates to a bridge reinforcement steel box girder structure. Background Technology

[0002] Steel box girders are a type of main load-bearing component commonly used in bridges, buildings, and other large structures. Due to their high strength, stiffness, and light self-weight, they are widely used in the design of bridges spanning large distances. Steel box girders are usually welded from steel plates, have a closed structure, and have good bending and torsional resistance.

[0003] If the steel box girder structure for bridge reinforcement is not firmly and accurately clamped on both sides during installation, it will lead to structural instability or low installation accuracy. Without the support of clamping and reinforcement, the steel box girder may shift, deform or loosen, affecting the overall load-bearing capacity and safety of the structure. Therefore, we provide a steel box girder structure for bridge reinforcement. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge reinforcement steel box girder structure, which uses a worm gear to drive a bidirectional threaded rod to rotate, thereby driving the clamping plates on both sides to accurately fix it. This solves the problem that if the existing bridge reinforcement steel box girder structure does not use clamping reinforcement during the installation process, it will lead to structural instability or low installation accuracy, and the lack of clamping reinforcement support will cause the steel box girder to shift position, deform or loosen.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a bridge reinforcement steel box girder structure, including a fixing block 101, a fixing mechanism is provided inside the fixing block 101, and a positioning and reinforcement mechanism is provided on the outer wall of the fixing block 101.

[0007] The fixing mechanism includes a second fixing block, the bottom of which is fixedly connected to the inner wall of a first fixing block 101. A first limiting rod is fixedly connected to the inner wall of the second fixing block. A bidirectional threaded rod is threadedly connected to the inner wall of the second fixing block. A clamping plate is threadedly connected to the outer surface of the bidirectional threaded rod. The inner wall of the clamping plate is slidably connected to the outer surface of the first limiting rod. A first telescopic spring is fixedly connected to the outer wall of the clamping plate. A pressure block is fixedly connected to the end of the outer wall of the first telescopic spring away from the clamping plate. A worm gear is fixedly connected to the outer wall of the bidirectional threaded rod. A worm is meshed at the top of the worm gear. A fixing sleeve is rotatably connected to the outer surface of the worm.

[0008] Furthermore, a total of several limiting rods are provided, two bidirectional threaded rods are provided, a total of several clamping plates are provided, and a total of several pressure blocks are provided.

[0009] Furthermore, the positioning and reinforcement mechanism includes a bridge pier, the outer wall of which is fixedly connected to the inner wall of the fixing sleeve.

[0010] Furthermore, a second fixed shaft is fixedly connected to the inner wall of the bridge pier, and a rotating plate is rotatably connected to the outer surface of the second fixed shaft. There are two rotating plates in total, and a first fixed shaft is fixedly connected to the inner wall of the rotating plate.

[0011] Rotating the worm gear drives the worm wheels on both sides to rotate, causing the two-way threaded rods on both sides to rotate simultaneously. This allows for precise and effective clamping of the steel box girder, providing additional support and preventing deformation or positional displacement. The telescopic spring plays a role in the clamping process, enabling finer adjustments, especially when the position of the steel box girder needs to be adjusted. The reaction force provided by the spring helps to achieve a stable and precise clamping effect.

[0012] Furthermore, a rotating block is rotatably connected to the outer surface of the fixed shaft, and a plurality of rotating blocks are provided. A fixed block is fixedly connected to the bottom of the rotating block.

[0013] Furthermore, a telescopic rod is fixedly connected to the bottom of the fixed block three, and a plurality of telescopic rods are provided. A telescopic spring two is fixedly connected to the bottom of the fixed block three.

[0014] Furthermore, the bottom of the second telescopic spring is fixedly connected to the bottom of the pier, the top of the pier is fixedly connected to a base, the top of the rotating plate is fixedly connected to a second limiting rod, and the outer surface of the second limiting rod is slidably connected to a movable plate.

[0015] Furthermore, a threaded rod is threadedly connected to the outer surface of the movable plate, and a fixed plate is threadedly connected to the outer surface of the threaded rod. The top of the second limiting rod is fixedly connected to the bottom of the fixed plate.

[0016] By using the weight of the steel box girder itself to press down the rotating plates on both sides, the threaded rods on both sides of the rotating plates can reinforce the two sides of the steel box girder, thus firmly fixing the steel box girder to the pier and effectively improving the stability of the steel box girder.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting a bidirectional threaded rod, allows for reinforcement of the steel box girder. When the worm gear is rotated, it drives the worm wheels on both sides to rotate, which in turn drive the bidirectional threaded rod. The bidirectional threaded rod then causes the clamping plates on both sides to slide linearly on the surface of the limiting rod. The clamping plates on both sides cause the telescopic spring and pressure block to gradually move towards both sides of the steel box girder. At this time, the telescopic spring is in an extended state. Then, when the pressure blocks on both sides contact the sides of the steel box girder, the clamping plates continue to move, and the telescopic spring is gradually compressed, generating a reverse force. When the appropriate tightness is adjusted, the fixation is completed. This effectively reinforces the steel box girder while the telescopic spring provides adjustable pressure, ensuring a more stable fixation and improving the reinforcement effect and construction accuracy.

[0019] 2. This utility model, by setting a rotating plate, allows for the installation of the steel box girder. First, the threaded rods on both sides are turned, causing the movable plate to slide along the limit rod two. Once adjusted to the highest point, the crane lifts the steel box girder directly above the center point of the rotating plates on both sides. The steel box girder is then slowly lowered, pressing down on the rotating plates on both sides. Simultaneously, the rotating plates rotate on the surface of the fixed shaft two to adjust their angle. Then, the rotating block rotates on the surface of the fixed shaft one, causing the bottom telescopic rod and the second telescopic spring to press down. The telescopic rod limits the movement of the second telescopic spring. As the steel box girder is fully lowered, the side of the rotating plates with threaded rods at the top will tightly adhere to both sides of the steel box girder. The threaded rods are then turned again to move the movable plate, firmly fixing the bottom of the movable plate to the top of the steel box girder. This completes the initial fixing. During the adjustment process, the threaded rods and telescopic rods effectively adjust the pressure, ensuring close contact between the rotating plate and the steel box girder. The precise lowering using the crane ensures stable and reliable reinforcement, improving construction efficiency and accuracy.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 As shown, this utility model is a bridge reinforcement steel box girder structure, including a fixing block 101, a fixing mechanism is provided inside the fixing block 101, and a positioning and reinforcement mechanism is provided on the outer wall of the fixing block 101.

[0031] The fixing mechanism 1 includes a second fixing block 109, the bottom of which is fixedly connected to the inner wall of the first fixing block 101. A limiting rod 110 is fixedly connected to the inner wall of the second fixing block 109. The limiting rod 110 can limit the movement of multiple clamping plates 103, ensuring their linear horizontal movement. A bidirectional threaded rod 108 is threadedly connected to the inner wall of the second fixing block 109. Rotating the bidirectional threaded rods 108 on both sides allows the clamping plates 103 on both sides to drive the pressure blocks 105 to effectively reinforce the steel box girder, thereby increasing stability and load-bearing capacity. A clamping plate 103 is threadedly connected to the outer surface of the bidirectional threaded rod 108. The inner wall of the clamping plate 103 is slidably connected to the outer surface of the limiting rod 110. A telescopic spring 104 is fixedly connected to the outer wall of the clamping plate 103. During clamping, as the bidirectional threaded rod 108 rotates continuously, the telescopic spring 104 will continuously compress the pressure blocks. 4. Extrusion is applied to ensure that the pressure block 105 can stably fix the steel box girder. The elastic characteristics of the telescopic spring 104 can effectively prevent over- or under-clamping due to improper adjustment of the bidirectional threaded rod 108. The end of the outer wall of the telescopic spring 104 away from the clamping plate 103 is fixedly connected to the pressure block 105. The outer wall of the bidirectional threaded rod 108 is fixedly connected to the worm wheel 107. The top of the worm wheel 107 is engaged with the worm 106. By rotating the worm 106, the worm wheels 107 on both sides can be rotated, thereby driving the bidirectional threaded rods 108 on both sides to rotate. The outer surface of the worm 106 is rotatably connected to the fixing sleeve 102. Several limit rods 110 are provided. Two bidirectional threaded rods 108 are provided. Several clamping plates 103 are provided. Several pressure blocks 105 are provided. The positioning and reinforcement mechanism 2 includes a pier 201. The outer wall of the pier 201 is fixedly connected to the inner wall of the fixing sleeve 102.

[0032] A fixed shaft 208 is fixedly connected to the inner wall of the pier 201. When the crane hoists the steel box girder above the center point of the rotating plates 202 on both sides, the steel box girder slowly descends and begins to press down on the center point of the rotating plates 202. At this time, the steel box girder presses down on the rotating plates 202, causing the rotating plates 202 to rotate on the surface of the fixed shaft 208. The side of the rotating plate 202 with the threaded rod 205 at its top clamps the steel box girder. Two rotating plates 202 are rotatably connected to the outer surface of the fixed shaft 208. The inner wall of the rotating plate 202 is fixedly connected to... A fixed shaft 207 is connected, which allows the rotating plate 202 to rotate in conjunction with the downward pressure of the steel box girder when the rotating plate 202 rotates. A rotating block 209 is rotatably connected to the outer surface of the fixed shaft 207. Several rotating blocks 209 are provided. A fixed block 210 is fixedly connected to the bottom of the rotating block 209. A telescopic rod 212 is fixedly connected to the bottom of the fixed block 210. Several telescopic rods 212 are provided. A telescopic spring 211 is fixedly connected to the bottom of the fixed block 210. The telescopic spring 211 can push the top rotating plate 202 to maintain an open posture when the steel box girder is not installed, which facilitates installation.

[0033] The bottom of the second telescopic spring 211 is fixedly connected to the bottom of the pier 201. The top of the pier 201 is fixedly connected to the base 213. The top of the rotating plate 202 is fixedly connected to the second limiting rod 204. The outer surface of the second limiting rod 204 is slidably connected to the movable plate 203. The outer surface of the movable plate 203 is threadedly connected to the threaded rod 205. By rotating the threaded rod 205, the movable plate 203 can be moved. At the same time, the second limiting rod 204 will limit the movable plate 203. Then, the movable plate 203 can be moved to the appropriate width for the installation of the steel box girder. The outer surface of the threaded rod 205 is threadedly connected to the fixed plate 206. The top of the second limiting rod 204 is fixedly connected to the bottom of the fixed plate 206.

[0034] One specific application of this embodiment is:

[0035] When installing the steel box girder, first tighten the threaded rods 205 on both sides. The threaded rods 205 will then cause the movable plate 203 to slide against the limit rod 204. Once adjusted to the highest point, the crane will lift the steel box girder directly above the center point of the rotating plates 202 on both sides. The steel box girder will then be slowly lowered. At this point, the steel box girder will press down on the rotating plates 202 on both sides, and the rotating plates 202 will rotate on the surface of the fixed shaft 208 to adjust their angle. Then, the rotating block 209 will rotate on the surface of the fixed shaft 207, causing the bottom telescopic rod 212 and the telescopic spring 211 to press down. Simultaneously, the telescopic rod 212 will limit the telescopic spring 211. As the steel box girder is fully lowered, the side of the rotating plates 202 with the threaded rods 205 at the top will tightly adhere to both sides of the steel box girder. Then, tighten the threaded rods 205 again. 5. Move the movable plate 203 to firmly fix the bottom of the movable plate 203 to the top of the steel box girder. This completes the initial fixing. When reinforcing the steel box girder again, rotate the worm gear 106. The worm gear 106 will then drive the worm wheels 107 on both sides to rotate. The worm wheels 107 will then drive the bidirectional threaded rod 108 to rotate. The bidirectional threaded rod 108 on both sides will then drive the clamping plate 103 on the surface of the limit rod 110 to slide linearly. The clamping plate 103 on both sides will drive the telescopic spring 104 and the pressure block 105 to gradually move towards both sides of the steel box girder. At this time, the telescopic spring 104 is in the extended state. Then, when the pressure blocks 105 on both sides contact the sides of the steel box girder, continue to move the clamping plate 103. Then the telescopic spring 104 will be gradually compressed and generate a reverse force. When the appropriate tightness is adjusted, the fixing is completed.
