Description

Technical Field

[0001] This utility model relates to the technical field of wind-resistant stabilization equipment for arch bridge rib construction, and in particular to a wind-resistant stabilization device for the construction of flexible arch bridge ribs with steel truss. Background Technology

[0002] The construction of the arch rib of an arch bridge is a complex and meticulous process. First, a detailed site survey is required, including topography, hydrogeology, meteorology, and other conditions, as well as available resources such as roads, electricity, and water. Simultaneously, technical preparations are undertaken, including drawing review, technical briefings, and the preparation of a construction organization design. Second, before pouring the tie beam concrete, the arch foot and lower anchor box must be pre-embedded. Based on the spatial coordinates of the arch axis center, the center of the upper steel pipe, and the center of the lower steel pipe, the arch rib steel pipes are positioned, adjusted, and then welded to form the framework. The pre-embedded lower anchor box must be positioned in conjunction with the arch rib anchor holes to ensure that the suspenders can smoothly pass through the arch rib and enter the lower anchor box.

[0003] The following problems exist: Existing bridge wind-resistant and stable structures often use longitudinal steel sections and V-shaped supports in the middle of the suspenders to temporarily enhance their stability. This method increases volume and weight, is costly, and is inconvenient to install. It not only increases the difficulty and risk of construction workers and reduces construction efficiency, but also results in low connection strength at the joints. After construction, the support steel sections are separated from the suspenders by cutting, which not only increases the difficulty of disassembling the support steel sections after construction, but also makes the support steel sections unusable, increasing construction costs.

[0004] Compared with the prior art application number 202020698949.4, a wind-resistant stabilization device for the arch rib construction of a flexible arch bridge with steel truss:

[0005] 1. This application uses a stable triangular structure composed of a tension rope, a U-shaped sliding plate, and a sliding shell, which balances the forces on the two sets of arch bridge frames and helps to improve the stability of the arch bridge; the prior art uses a square structure, so its stability is weaker.

[0006] 2. This application uses a suction cup fixing structure, which makes the suction cup installation and removal steps more convenient and quick, and also reduces the cost; the prior art uses fasteners, which are more expensive and inconvenient to install and remove.

[0007] 3. This application uses a height-adjustable sliding shell structure, which can adjust the triangular structure according to the height of the arch bridge frame, thereby making the triangular force distribution more even; the prior art lacks this adjustment structure.

[0008] 4. This application features a dedicated winding box for winding up the pull rope. When in use, simply pull the pull rope out of the winding box, making the entire operation more convenient. When the pull rope is damaged, only the pull rope in the individual winding box needs to be replaced, eliminating the need to replace all pull ropes and thus reducing costs. In contrast, the connecting rope in the comparative document is an integrated structure, resulting in higher replacement costs. Utility Model Content

[0009] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0010] To solve the above problems, the present invention adopts the following technical solution.

[0011] A wind-resistant stabilization device for the construction of a flexible arch bridge rib using a steel truss includes a bridge body. Arch bridge frames are fixedly connected to both ends of the top of the bridge body. Multiple sets of U-shaped placement seats are placed on the top of the bridge body. A U-shaped sliding plate is fixedly connected to the top of each U-shaped placement seat. A sliding shell is slidably connected to the inner wall of each U-shaped sliding plate. A first hanging ring is fixedly connected to the top of each of the two outer walls of the sliding shell. A hook is sleeved on the inner wall of each first hanging ring. Multiple sets of suction cups are movably connected to the opposite faces of the two sets of arch bridge frames. A second hanging ring is fixedly connected to the top of each suction cup. A pull rope is fixedly connected to the bottom of each hook. The outer wall of each pull rope is sleeved with the inner wall of the second hanging ring. A winding box is fixedly connected to the bottom of each of the two outer walls of the U-shaped sliding plate. A wire inlet hole is opened at the other end of the top of each winding box, and the outer wall of each pull rope is slidably connected to the inner wall of the wire inlet hole.

[0012] As a further description of the above technical solution:

[0013] Each of the U-shaped sliding plates has a forward and reverse motor running through its bottom center, and the movable end of each forward and reverse motor is rotatably connected to a threaded column.

[0014] As a further description of the above technical solution:

[0015] The outer wall of each threaded column is threadedly connected to a threaded sleeve, and the sliding shell has a through-hole, with the inner wall of the hole fixedly connected to the outer wall of the threaded sleeve.

[0016] As a further description of the above technical solution:

[0017] A hollow plate is fixedly connected to the top of each of the winding boxes, and a threaded rod is threadedly connected to the inner wall of each hollow plate.

[0018] As a further description of the above technical solution:

[0019] One end face of each threaded rod is rotatably connected to a rotating shaft, and the bottom end of each rotating shaft is fixedly connected to a pressure plate.

[0020] As a further description of the above technical solution:

[0021] Each of the winding boxes has a servo motor running through its front end, and the movable end of each servo motor is rotatably connected to a winding roller. One end of the outer wall of each winding roller is fixedly connected to the end of a pull rope.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] (1) The pull rope passing through the second hanging ring forms a stable triangular structure with the U-shaped sliding plate and the sliding shell, which supports and fixes the arch bridge frame, thus achieving a good wind resistance effect. The suction cup can be quickly removed from the arch bridge frame, making the entire wind-resistant stabilizing device easier to disassemble. When the servo motor drives the winding roller to rotate, it can wind up the pull rope, which can not only quickly tighten the pull rope, but also recycle and reuse the pull rope, which not only saves construction costs, but also improves the safety of the construction environment of the arch rib of the arch bridge.

[0024] (2) When the threaded rod rotates, the rotating threaded rod can move back and forth inside the hollow plate. At the same time, the pressure plate on the rotating shaft will also move back and forth. When the pressure plate presses on the outer wall of the pulling rope, the pulling rope can be fixed. When the forward and reverse motor drives the threaded column to rotate, the threaded sleeve can move up and down on the outer wall of the rotating threaded column. At the same time, the sliding shell will also slide up and down, which makes it convenient to connect and fix the arch bridge frame of different heights. Attached Figure Description
