Space inhaul cable anti-collision vibration-isolation type universal connection device and manufacturing and mounting methods thereof

Abstract

A space inhaul cable anti-collision vibration-isolation type universal connection device comprises two semicircular cable hoop assemblies which are each composed of an A-type semicircular cable hoop and a B-type semicircular cable hoop, and a buffering type universal rotary connector assembly. The every two semicircular cable hoops are connected together through a connecting bolt I in a fastened mode, and PE cable bodies are fixed and connected together through the connecting bolts I; the buffering type universal rotary connector assembly comprises a high-damping elastomer, two universal ballbearings located at the two ends of the high-damping elastomer correspondingly, a compression spring and an elastic sealing body, wherein the compression spring and the elastic sealing body are located in the high-damping elastomer; the universal ball bearings are provided with threaded holes, and the universal ball bearings and the two semicircular cable hoop assemblies are connected together through connecting bolts II, so that the two semicircular cable hoop assemblies and the buffering type universal rotary connector assembly are connected together in a fastened mode to form the space inhaul cable anti-collision vibration-isolation type universal connection device. According to the space inhaul cable anti-collision vibration-isolation type universal connection device, collision betweenthe cables can be prevented, mutual dragging between cable bodies is achieved, and the vibration isolation and reduction effects are achieved; and the demand of multi-angle connection of the space inhaul cables can be met.

Description

technical field [0001] The invention relates to a space cable anti-collision vibration isolation device, in particular to a space cable anti-collision vibration isolation universal connection device and a manufacturing and installation method thereof. Background technique [0002] Both the double cables of the bridge and the cables of the stadium have the phenomenon that the cables in the free section are prone to wind and rain vibration, which leads to the phenomenon that the cables are easy to shake and collide at close distances, especially in the space cross cables, so how to solve this problem? Problem, there are several following methods on the market, but there are many deficiencies. [0003] Method 1: Use steel wire ropes to string adjacent cables together to form a series cable net (see Figure 8 ), this type of connection is relatively thin, and the contact surface with the cable body is small and difficult to tighten. It needs to be wound multiple times and fixed ...

[0002] Both the double cables of the bridge and the cables of the stadium have the phenomenon that the cables in the free section are prone to wind and rain vibration, which leads to the phenomenon that the cables are easy to shake and collide at close distances, especially in the space cross cables, so how to solve this problem? Problem, there are several methods in the market, but there are many deficiencies

[0003] Method 1: Use steel wire ropes to string adjacent cables together to form a series cable net (see Figure 8 ), this type of connection is relatively thin, and the contact surface with the cable body is small and difficult to tighten. It needs to be wound multiple times and fixed by other locking devices, which is easy to cause damage to the surface of the cable body; secondly, the large-area series cable net It affects the aesthetics of the cable, and the single function of the steel wire rope cannot realize the functions of vibration absorption and buffering, and there is no way to achieve the effect of reducing the amplitude of the cable

[0004] Method two, adopt the steel cable clamp connection mode, this cable clamp is to adopt the steel structure completely, the rigidity is bigger and the structure function is single, also has no cushioning, the patent publication number is CN1730829A, and the invention title is "the anti-corrosion of bridge cable Wind Vibration Damping Thread Clamp" is one of them (see Figure 9 ), the two parts of the cable clamp are completely connected by screws, and the whole device is a steel structure, and the steel cable clamp cannot meet the requirements of multi-directional and multi-angle space steering and elastic buffering and vibration absorption for space cables.
