Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] Such as figure 1 As shown, the hydraulic submarine cable bridge of the present invention includes a bridge main body 1 , a luffing cylinder 2 , a rotating cylinder 3 , a cable bridge winch 4 , a self-rotating base 5 and a base 6 .

[0012] The bridge main body 1 is connected to the spin base 5 through the cable bridge winch 4, and the bridge main body 1 and the cable bridge winch 4 are connected by rotation along the vertical direction of the bridge axis, and the bridge main body 1 and the spin base 5 A luffing oil cylinder 2 is connected, and a rotating oil cylinder 3 is installed between the spin base 5 and the base 6 .

[0013] The main body of the bridge frame 1 is made of a steel structure truss, the structure is light in weight, and its line shape meets the minimum bending radius requirement of the submarine cable.

[0014] The luffing cy...

Abstract

The invention relates to a hydraulic submarine cable cable-passing bridge frame which is composed of a bridge frame body, an amplitude-changing oil cylinder, a rotation oil cylinder, a cable-passing bridge frame hinged seat and a self-rotating type pedestal. The bridge frame body is connected with the self-rotating type pedestal via the cable-passing bridge frame hinged seat, and the bridge frame body and the cable-passing bridge frame hinged seat are connected in a rotating way along a vertical direction of a bridge frame axis. The amplitude-changing oil cylinder is connected between the bridge frame body and the self-rotating type pedestal. The rotation oil cylinder is connected between the self-rotating type pedestal 5 and a pedestal. With combination of a self-rotating type cable-bearing disc, stress of a submarine cable can be released via movement of the cable-passing bridge frame during the laying process of the submarine cable, and damage generated by suddenly increased stress on the submarine cable during the construction process is ensured to be avoided.

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...
