Embodiment

[0019] A cable retractable arc device, its structure is as follows figure 1 As shown, the device is arranged on the bridge deck 5 and includes a clamp 1 , a guide rail 2 , a cable 3 and a slide plate 4 . The fixture 1 is a movable fixture that can rotate and move obliquely along the chute. It is clamped on the cable 3. The guide rail 2 is set on one side of the cable 3. The lower part of the guide rail 2 is provided with an oil-free sliding bearing or a guide wheel, so that it can Applicable to different situations, the cable 3 is connected to the clamp 1 on one side via the guide rail 2 . The cables 3 are arranged in an arch bridge-like structure, and 4 to 8 cables can be arranged as required. In this embodiment, there are 6 cables.

[0020] In the present invention, cables with sufficient length are reserved in advance, and the cables are arranged and shaped under the condition of satisfying the bending radius of the cables. When cable elongation or shrinkage occurs, the r...

Abstract

The present invention relates to a cable telescopic arc device which comprises a clamp, a guide rail, a cable and a sliding plate. The clamp is arranged on the sliding plate. The cable is connected with the clamp at a side by the guide rail. The cable is set as an arch bridge structure. The sliding plate is arranged at a position of the arch bridge structure of the cable. Compared with the prior art, according to the invention, a conventional cable is used to substitute an expensive submarine cable, economical efficiency is high, a power cable is laid through a bridge, a channel is provided for the future repair and maintenance of the cable, the reliability of cable operation is greatly raised, moreover, the cable can cope with expansion and contraction amplitudes of the bridge, and a service life of the cable is long.

Description

technical field [0001] The invention relates to a cable structure, in particular to a cable telescopic arc device. Background technique [0002] In recent years, with the development of regional economy and the refinement of regional positioning, the domestic development and utilization of offshore islands has become increasingly heated and paid more and more attention. Many islands across the country have been turned into shipbuilding bases, power generation bases, gas transfer stations, port terminals, etc., including Shanghai's Changxing Island Shipbuilding Base and Xiaoyangshan Island Port Base. In order to cooperate with the preparation of these bases and solve the long-term material transportation problems, local governments are often willing to build bridges to connect the islands and the mainland. This provides a new way to solve the power transmission problem that has plagued the island for a long time. [0003] Compared with the submarine cable mode, the use of m...
