Description

Technical Field

[0001] This utility model relates to the field of wire drawing bridge construction technology, and in particular to an auxiliary guiding structure for the installation of wire drawing bridge cable strands. Background Technology

[0002] Cable strands in bridge construction are key load-bearing components of long-span bridges. They are mainly composed of multiple high-strength steel wires or strands assembled through a specific process. These strands bear the weight of the entire bridge superstructure and transfer it to the bridge towers and anchorages. Their diameter can range from tens of millimeters to hundreds of millimeters, and their length depends on the bridge span; the larger the span, the longer the strands.

[0003] During installation, cable strands are easily affected by external forces and may shift during traction, causing the spacing between the strands to fail to meet design requirements. Furthermore, if the cable strands come into direct contact with other structural components of the bridge, the weight of the strands and the traction tension will generate significant friction. This will not only increase the pulling force required to pull the cable strands but may also cause wear on the steel wires or strands on the surface of the strands, thereby reducing the installation effect.

[0004] To address this, an auxiliary guiding structure for the installation of cable strands in wire-drawing bridge construction is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary guiding structure for the installation of cable strands in wire-drawn bridge construction. This structure can solve the problems of existing cable strands being easily affected by external forces during installation, causing them to shift and resulting in the spacing between the strands not meeting design requirements. Furthermore, if the cable strands are in direct contact with other structural components of the bridge, the weight of the strands and the traction tension will generate significant friction, which will not only increase the pulling force required to pull the cable strands but may also cause wear on the steel wires or strands on the surface of the strands, thereby reducing the installation effect.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This application provides a guide component that allows the cable strand to move smoothly in the horizontal direction and provides stable support for the cable strand, ensuring that the cable strand moves along a preset horizontal path and avoiding large deviations in the horizontal direction.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A wire drawing bridge construction cable strand installation auxiliary guide structure includes a movable base 1, a guide component 2 is provided on the top of the movable base 1, an adjustment component 3 is provided inside the guide component 2, and the adjustment component 3 includes a connecting rod 301.

[0027] The guide assembly 2 includes a guide frame 201, a guide roller 202, a mounting groove 203, a mounting plate 204, and a limiting roller 205. The guide frame is located on the top of the movable base 1. The guide roller 202 is rotatably connected to the inside of the guide frame 201. The mounting groove 203 is opened on both sides of the inner wall of the guide frame 201. The mounting plate 204 is movably connected to the inside of the mounting groove 203. The limiting roller 205 is rotatably connected to the inside of the mounting plate 204. The number of guide rollers 202 and limiting rollers 205 is set to several and evenly distributed.

[0028] In this embodiment: by setting the guide component 2, the guide roller 202 can make the cable strand move smoothly in the horizontal direction and provide stable support for the cable strand, ensuring that the cable strand moves along the preset horizontal path. The limiting roller 205 can limit the cable strand from both sides to prevent the cable strand from shaking or deviating from the center position in the vertical direction, thereby ensuring the vertical accuracy of the cable strand installation. The mounting plate 204, through its tight cooperation with the mounting groove 203, can ensure the positional accuracy of the mounting plate 204 during the movement process, thereby improving the accuracy of the position adjustment of the limiting roller 205.

[0029] Specifically, such as Figure 4 , Figure 5 As shown, the connecting rod 301 passes through the guide frame 201 and is slidably connected to the guide frame 201. The top of the connecting rod 301 is fixedly connected to the moving block 302, and the interiors of the two moving blocks 302 are threadedly connected to a bidirectional threaded rod 303.

[0030] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a groove 4 is provided at the bottom of the guide frame 201. A drive motor 304 is fixedly connected inside the groove 4. The output end of the drive motor 304 is fixedly connected to the bidirectional threaded rod 303, and the bidirectional threaded rod 303 is rotatably connected to the side of the inner wall of the groove 4.

[0031] Specifically, such as Figure 3 As shown, limit grooves 5 are provided on the front and rear sides of the inner wall of the groove 4, and limit blocks 6 are fixedly connected to the front and rear sides of the moving block 302. The limit blocks 6 are slidably connected inside the limit grooves 5.

[0032] In this embodiment: by setting the adjustment component 3, when the two moving blocks 302 move towards or away from each other under the drive of the bidirectional threaded rod 303, the moving blocks 302 can drive the mounting plate 204 to move synchronously through the connecting rod 301, so that the distance between the two limiting rollers 205 can be adjusted. Thus, the position of the limiting rollers 205 can be flexibly adjusted according to the size of the strand, improving the versatility of use. Furthermore, the cooperation of the limiting block 6 and the limiting groove 5 can restrict the movement trajectory of the moving blocks 302, thereby improving the stability of the limiting rollers 205 during adjustment.

[0033] Specifically, such as Figure 1 , Figure 2 As shown, the top of the movable base 1 is provided with a movable groove 7, and a hydraulic telescopic device 8 is fixedly connected inside the movable groove 7. A T-shaped block 9 is fixedly connected to the telescopic end of the hydraulic telescopic device 8.

[0034] Specifically, such as Figure 2 As shown, a connecting block 10 is fixedly connected to the bottom of the guide frame 201, and a rotating rod 11 is rotatably connected to the surface of the T-shaped block 9 and the connecting block 10.

[0035] In this embodiment: With the above settings, the hydraulic telescopic device 8 can drive the T-block 9 to move linearly in the moving groove 7. When the T-block 9 moves, it will drive the rotating rod 11 to rotate around the connection point with the connecting block 10, so that the connecting block 10 and the guide frame 201 will have a certain tilt angle relative to the moving base 1, thereby achieving the effect of adjusting the angle of the guide frame 201, so that the cable strand can adapt to complex cable strand laying paths, and further improve versatility.

[0036] Specifically, such as Figure 1 As shown, guide grooves 12 are provided on both sides of the inner wall of the moving groove 7. A guide rod 13 is fixedly connected inside the guide groove 12. A guide block 14 is slidably connected to the surface of the guide rod 13. The guide block 14 is fixedly connected to both sides of the connecting block 10.

[0037] Specifically, such as Figure 2 As shown, a rotating frame 15 is fixedly connected to the side of the movable base 1 and the guide frame 201 that are close to each other, and a telescopic support rod 16 is rotatably connected inside the rotating frame 15.

[0038] In this embodiment: by setting guide block 14 and guide rod 13, the cooperation of guide block 14 and guide rod 13 can ensure that T-block 9 moves stably along a preset direction, prevent horizontal deviation or swaying of guide frame 201, and ensure the stability of guide frame 201 when adjusting angle. By setting telescopic support rod 16, telescopic support rod 16 can provide additional support force for guide frame 201, enhance the stability of guide frame 201 at different positions, and keep guide frame 201 in a stable state at all times.

[0039] Working principle: First, place the cable strand on top of the guide roller 202, then fix one end of the cable strand to the traction device. Next, start the drive motor 304, which will drive the bidirectional threaded rod 303 to rotate. The rotation of the bidirectional threaded rod 303 will cause the two moving blocks 302 to move relative to or away from each other. The moving blocks 302 will then drive the connecting rod 301, mounting plate 204, and limiting rollers 205 to move synchronously. Then, adjust the distance between the two limiting rollers 205 to an appropriate position according to the actual size of the cable strand. When the cable strand is subjected to traction, it will move at the top of the guide roller 202 and the two… The limit rollers 205 roll together to ensure that the cable strands move along the preset horizontal path. When it is necessary to adjust the installation path of the cable strands, the hydraulic telescopic device 8 is activated. The hydraulic telescopic device 8 will drive the T-block 9 to move linearly in the moving groove 7. When the T-block 9 moves, it will drive the rotating rod 11 to rotate around the connection point with the connecting block 10, so that the connecting block 10 and the guide frame 201 will have a certain tilt angle relative to the moving base 1, thereby achieving the effect of adjusting the angle of the guide frame 201. Finally, according to the usage requirements, the guide frame 201 can be adjusted to a suitable angle.

[0040] It should be noted that the specific structure, usage method and working principle of the traction equipment in this application are all existing technologies, and therefore are not described in detail in the text.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
