Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cable-stayed bridge cable installation devices, and in particular to a cable-stayed bridge cable installation angle adjustment and positioning device. Background Technology
[0002] The cable-stayed bridge cable installation angle adjustment and positioning device is a special mechanical structure or equipment system used to precisely control the installation angle of the cable stays. Its design and function are directly related to the stress performance, construction accuracy and structural safety of the cable-stayed bridge.
[0003] However, in the existing technology, some cable-stayed bridge cable installation angle adjustment and positioning devices have the drawback of low automation. During the angle adjustment process, they still rely heavily on manual operation, which not only results in high labor costs, slow adjustment speed and low construction efficiency, but also makes it difficult to avoid errors in manual operation, leading to insufficient accuracy and consistency in angle adjustment, which is difficult to meet the requirements of modern bridge engineering for high-precision and high-efficiency construction. Utility Model Content
[0004] This utility model mainly provides a stable and efficient cable-stayed bridge cable installation angle adjustment and positioning device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cable-stayed bridge cable installation angle adjustment and positioning device, comprising an adjustment mechanism, a fixing mechanism installed inside the adjustment mechanism, and a limit mechanism installed on the upper part of the adjustment mechanism. The adjustment mechanism includes a first mounting frame, a first fixing frame fixedly connected to the inner side of the first mounting frame, and a second fixing frame slidably connected to the inner side of the first mounting frame. A first hydraulic cylinder is installed between the first fixing frame and the second fixing frame. The fixing mechanism includes a second mounting frame, a second mounting frame fixedly connected to the second fixing frame, and a base fixedly connected to the upper part of the second mounting frame. A second hydraulic cylinder is fixedly connected to the upper part of the base, and a clamping plate is fixedly connected to the end of the second hydraulic cylinder.
[0006] Preferably, a guide rail is fixedly connected to the surface of the base, and the bottom of the clamping plate is slidably connected to the inside of the guide rail. When the clamping plate clamps and fixes the cable, the clamping plate slides along the guide rail, which limits the movement of the clamping plate and its position after fixing the cable, thereby improving the stability during and after fixing.
[0007] Preferably, the bottom of the first mounting frame is fixedly connected to a mounting plate, and the fixed installation with the bridge deck is achieved through the mounting plate at the bottom of the first mounting frame.
[0008] Preferably, the limiting mechanism includes a slide rail, which is fixedly connected to the upper part of the first mounting frame, and a slider is slidably connected inside the slide rail. The slider is fixedly connected to the second fixing frame. When the second fixing frame slides along the first mounting frame, the slider slides along the slide rail, thereby limiting the movement of the second fixing frame and improving the stability of the second fixing frame when adjusting the cable angle.
[0009] Preferably, a limiting rod is fixedly connected to the side of the second fixing frame, and the limiting rod is slidably inserted into the first fixing frame. The limiting rod slides along the first fixing frame, thereby limiting the movement of the second fixing frame and improving the stability of the second fixing frame when adjusting the cable angle.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] 1. In this utility model, the installation plate at the bottom of the No. 1 mounting frame is used to fix the cable to the bridge deck. The No. 2 hydraulic cylinder pushes the clamping plate to automatically clamp and fix the cable end, replacing the traditional manual operation. Then, the No. 2 fixing frame is driven by the No. 1 hydraulic cylinder to slide within the No. 1 mounting frame, realizing the automatic adjustment of the cable angle. This solution, with the help of the hydraulic drive system of the No. 1 and No. 2 hydraulic cylinders, greatly reduces the dependence on manual operation. It not only improves the speed and construction efficiency of cable angle adjustment, but also ensures the accuracy and consistency of angle adjustment through mechanical automation. At the same time, the sliding design of the No. 2 fixing frame within the No. 1 mounting frame can flexibly adapt to different angle adjustment needs, effectively solving the problems of low efficiency and poor accuracy of manual operation in the prior art, and meeting the high-precision construction requirements of modern bridge engineering.
[0012] 2. In this utility model, by setting a guide rail on the base, the clamping plate can slide along the guide rail in a directional manner when it clamps the cable under the push of the No. 2 hydraulic cylinder, effectively limiting its swaying and displacement, and significantly enhancing the stability of the cable fixing. At the same time, the sliding structure composed of the slide rail and the slider, together with the sliding insertion of the limiting rod and the No. 1 fixing frame, forms a double limiting constraint on the movement path of the No. 2 fixing frame when the No. 1 hydraulic cylinder drives the No. 2 fixing frame to adjust the cable angle, avoiding lateral displacement or tilting during the sliding process, ensuring that the cable angle adjustment process is smooth and accurate. From the two key aspects of fixing and adjustment, the stability and reliability of the positioning device are comprehensively improved, ensuring the high precision and safety of the cable-stayed bridge cable installation.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Please see Figures 1-4 This utility model provides a cable-stayed bridge cable installation angle adjustment and positioning device, including an adjustment mechanism 1, a fixing mechanism 2 installed inside the adjustment mechanism 1, and a limit mechanism 3 installed on the upper part of the adjustment mechanism 1. The adjustment mechanism 1 includes a first mounting frame 11, a first fixing frame 12 fixedly connected to the inner side of the first mounting frame 11, and a second fixing frame 13 slidably connected to the inner side of the first mounting frame 11. A first hydraulic cylinder 14 is installed between the first fixing frame 12 and the second fixing frame 13. The fixing mechanism 2 includes a second mounting frame 21, which is fixed to the second fixing frame 13. The connection is made so that a base 22 is fixedly connected to the upper part of the second mounting frame 21, a second hydraulic cylinder 24 is fixedly connected to the upper part of the base 22, and a clamping plate 25 is fixedly connected to the end of the second hydraulic cylinder 24. The end of the cable that needs to be moved and adjusted is placed inside the clamping plate 25. The clamping plate 25 is clamped and fixed by the second hydraulic cylinder 24. Then, the second fixing frame 13 is slid along the first mounting frame 11 by the lifting of the first hydraulic cylinder 14, thereby adjusting the position of the fixing mechanism 2 and the fixed end of the cable, thereby adjusting the overall angle of the cable.
[0021] The second hydraulic cylinder 24 pushes the clamping plate 25 to automatically clamp and fix the end of the cable, replacing the traditional manual operation. Then, the first hydraulic cylinder 14 drives the second fixing frame 13 to slide within the first mounting frame 11, realizing the automatic adjustment of the cable angle. This solution, with the help of the hydraulic drive system of the first and second hydraulic cylinders 14, greatly reduces the dependence on manual operation. It not only improves the speed and construction efficiency of cable angle adjustment, but also ensures the accuracy and consistency of angle adjustment through mechanical automation. At the same time, the sliding design of the second fixing frame 13 within the first mounting frame 11 can flexibly adapt to different angle adjustment needs, effectively solving the problems of low efficiency and poor accuracy of manual operation in the existing technology, and meeting the high-precision construction requirements of modern bridge engineering.
[0022] like Figure 4 As shown: The base 22 is fixedly connected to the guide rail 23, and the bottom of the clamping plate 25 is slidably connected to the inside of the guide rail 23. When the clamping plate 25 clamps and fixes the cable, the clamping plate 25 slides along the guide rail 23, which limits the movement of the clamping plate 25 and its position after fixing the cable, thereby improving the stability during and after fixing.
[0023] like Figure 1 As shown: The bottom of the first mounting bracket 11 is fixedly connected to a mounting plate, and the fixed installation with the bridge deck is achieved through the mounting plate at the bottom of the first mounting bracket 11.
[0024] like Figure 1 As shown: The limiting mechanism 3 includes a slide rail 31, which is fixedly connected to the upper part of the first mounting frame 11. A slider 32 is slidably connected inside the slide rail 31. The slider 32 is fixedly connected to the second fixing frame 13. When the second fixing frame 13 slides along the first mounting frame 11, the slider 32 slides along the slide rail 31, thereby limiting the movement of the second fixing frame 13 and improving the stability of the second fixing frame 13 when adjusting the cable angle.
[0025] like Figure 1 As shown: A limiting rod 33 is fixedly connected to the side of the second fixing frame 13, and the limiting rod 33 is slidably inserted into the first fixing frame 12. The limiting rod 33 slides along the first fixing frame 12, thereby limiting the movement of the second fixing frame 13 and improving the stability of the second fixing frame 13 when adjusting the angle of the cable.
[0026] By setting guide rail 23 on base 22, the clamping plate 25 can slide along guide rail 23 when it clamps the cable under the push of the second hydraulic cylinder 24, effectively limiting its sway and displacement, and significantly enhancing the stability of cable fixing. At the same time, the sliding structure composed of slide rail 31 and slider 32, together with the sliding insertion of limit rod 33 and first fixing frame 12, forms a double limit constraint on the movement path of second fixing frame 13 when the first hydraulic cylinder 14 drives second fixing frame 13 to adjust the cable angle, avoiding lateral displacement or tilting during the sliding process, ensuring that the cable angle adjustment process is smooth and accurate. From the two key links of fixing and adjustment, the stability and reliability of the positioning device are comprehensively improved, ensuring the high precision and safety of cable-stayed bridge cable installation.
[0027] The method of use and working principle of this device: The mounting plate at the bottom of the first mounting frame 11 is installed and fixed to the preset position on the bridge deck. The end of the cable that needs to be moved and adjusted is placed inside the clamping plate 25. The clamping plate 25 is pushed by the second hydraulic cylinder 24 to clamp and fix the end of the cable. Then, the second fixing frame 13 is slid along the first mounting frame 11 by the lifting of the first hydraulic cylinder 14, thereby adjusting the position of the fixing mechanism 2 and the fixed end of the cable, thereby adjusting the overall angle of the cable.
[0028] When the clamping plate 25 clamps and fixes the cable, the clamping plate 25 slides along the guide rail 23, limiting the movement of the clamping plate 25 and its position after fixing the cable, thus improving the stability during and after fixing. When the second fixing frame 13 slides along the first mounting frame 11, the slider 32 slides along the slide rail 31, and at the same time the limiting rod 33 slides along the first fixing frame 12, thereby limiting the movement of the second fixing frame 13 and improving the stability of the second fixing frame 13 when adjusting the angle of the cable.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
