Description

Technical Field

[0001] This application relates to the field of bridge construction equipment technology, and in particular to a temporary cable installation device. Background Technology

[0002] In suspension bridge construction, the installation of temporary cables is a crucial step in ensuring the formation of the main cable and the safety of subsequent construction. Traditional construction methods typically rely on large lifting equipment or manual high-altitude work, which is not only inefficient but also poses significant safety risks. As the span of suspension bridges continues to increase, higher demands are placed on the precision and efficiency of temporary cable installation.

[0003] Currently, the main methods for installing temporary cables under relevant technologies include: First, directly hoisting the temporary cables using large lifting equipment such as tower cranes or crawler cranes. This method completes the hoisting operation through a robotic arm, but requires a large construction site and is limited by the boom length and lifting capacity of the lifting equipment. Second, performing high-altitude operations by manually erecting scaffolding or suspending baskets. Although this method is more flexible, the construction period is long and there are significant safety hazards. In addition, some technologies have attempted to use simple traction devices, such as using simple pulley blocks and wire ropes to traction the temporary cables, but due to imperfect structural design and poor positioning accuracy, they are difficult to meet actual needs.

[0004] Regarding the aforementioned technologies, all existing technologies have certain shortcomings. Large lifting equipment is costly to operate and has poor adaptability to complex terrain conditions; manual high-altitude operations are not only inefficient but also pose significant safety risks; while simple traction devices reduce construction difficulty to some extent, their lack of systematicity and reliability prevents them from meeting the high-precision installation requirements of long-span suspension bridges. These problems urgently need to be addressed through innovative technological means. Utility Model Content

[0005] To improve the efficiency and accuracy of temporary cable installation for long-span suspension bridges, this application provides a temporary cable installation device.

[0006] This application provides a temporary cable installation device, which adopts the following technical solution:

[0010] By adopting the above technical solution, and by setting up pulleys and a winch, when it is necessary to move the temporary sling, the winch is started. The winch drives the temporary sling to the saddle via the steel strand for easy installation. The pulleys can support the winch's steel strand and the temporary sling, and can also control the direction of the temporary sling, effectively improving the installation efficiency, accuracy and construction safety of the temporary sling.

[0037] This application discloses a temporary cable installation device. (Refer to...) Figure 1 and Figure 2 A temporary cable installation device includes a frame 1, a pulley 2, a winch 3, and a temporary sling 4. The frame 1 is detachably installed on the main cable 01. The pulley 2 is rotatably connected to the frame 1, and the pulley 2 is parallel to the first direction along the rotation axis of the frame 1. The winch 3 is located on the bridge deck, and the steel strand of the winch 3 is wound around the pulley 2 and then fixedly connected to the temporary sling 4. In use, the winch 3 is started, and the winch 3 moves the temporary sling 4 through the steel strand to the cable saddle so that the temporary sling 4 can be installed.

[0038] Reference Figure 2To facilitate the installation of the frame 1, the temporary cable installation device also includes a temporary cable clamp 5. The temporary cable clamp 5 is installed on the main cable 01, and the frame 1 is detachably connected to the temporary cable clamp 5. By setting the temporary cable clamp 5, the main cable 01 is connected to the bridge deck, and the frame 1 is supported. Specifically, the frame 1 and the temporary cable clamp 5 are fixed by a first locking member 11. One end of the first locking member 11 passes through the frame 1 and is threaded to the temporary cable clamp 5.

[0046] Reference Figure 4 To further improve the stability of the limiting member 81 on the main cable clamp 51, a fourth mounting base 513 is detachably connected to the top wall of the main cable clamp 51. The third mounting base 82 is fixedly connected to the fourth mounting base 513 by screws, thereby further improving the stability of the limiting member 81.
