Abstract

The invention relates to a hydraulic submarine cable bridge, which is composed of a bridge main body, a luffing oil cylinder, a rotating oil cylinder, a cable bridge winch and a self-rotating base. The main body of the bridge is connected to the self-rotating base through the cable bridge winch, and The main body of the bridge frame and the winch of the cable bridge frame are connected by rotation along the vertical direction of the axis of the bridge frame. A luffing oil cylinder is connected between the main body of the bridge frame and the spin base, and a rotary oil cylinder is installed between the spin base 5 and the base. The present invention combines the spin-type cable bearing reel, can release the stress of the submarine cable through the movement of the cable bridge during the laying process of the submarine cable, and can ensure that the submarine cable will not be damaged due to the sudden increase of stress during the construction process.

Description

technical field [0001] The invention relates to a hydraulic submarine cable bridge for releasing the instantaneous stress of the cable during laying of the submarine cable. Background technique [0002] At present, domestic submarine cable laying mostly adopts the cable laying process of the cable ring and the fixed back-twist frame; the more advanced one adopts the self-rotating cable support plate and the fixed cable frame laying process. All of the above-mentioned processes have the problem that the submarine cable stress caused by the instantaneous change of ship displacement cannot be released during the laying process of the submarine cable. Contents of the invention [0003] In order to overcome the above-mentioned problems existing in the existing submarine cable laying process, the present invention provides a hydraulic submarine cable bridge frame, which can release the stress of the submarine cable through the movement of the cable bridge frame in the process of...
