Embodiment Construction

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] like figure 1 As shown, the cable turntable of the present invention includes a hydraulic turntable 2, a cable bridge, a bearing plane bearing 4, a transmission internal gear 7, a driving gear 8, a hydraulic motor 5, and the like.

[0013] The hydraulic turntable 2 is installed on the construction vessel and may rotate in forward and reverse directions. The inlet and outlet of the cable bridge can be adjusted left, right, up and down. The base of the hydraulic turntable 2 and the installation deck 3 of the construction ship are movably connected by the bearing plane bearing 4. The transmission internal gear 7 is fixedly installed under the base of the hydraulic turntable 2, which is connected with the transmission The drive gear 8 meshed with the internal gear 7 is fixed on the output shaft of the hydraulic motor 5 whose speed, torque and power ca...

Abstract

The invention relates to a cable turntable. The cable turntable comprises a hydraulic turntable and a cable crossing bridge, wherein the hydraulic turntable is arranged on a construction vessel and can rotate in a positive direction and a negative position, and the cable crossing bridge can be adjusted upwards, downwards, leftwards and rightwards. A base of the hydraulic turntable is movably connected with a mounting deck of the construction vessel by bearing a plane bearing; the downside of the base of the hydraulic turntable is provided with a driving internal gear; a driving gear meshed with the driving internal gear is fixed on an output shaft of a hydraulic motor of which the speed, the torque and the power can be adjusted steplessly; and the hydraulic motor is fixed on a fixed seat of the mounting deck. The maximum bearing capacity of the cable turntable is 1,500 tons, and the outer diameter of the cable turntable is 18 meters. The stepless speed change range of the speed of the hydraulic turntable is 0 to 0.063 rad / s. By adopting a back-twisting mode, the cable turntable not only can satisfy the back twisting of marine cables, but also can solve the problem of difficult mounting.

Description

technical field [0001] The invention relates to a submarine cable untwisting device, in particular to a submarine cable untwisting device used to meet the untwisting requirements of various forms of submarine cables and optical cables as well as special structures and requirements. Background technique [0002] At present, the known back-twist method in the field of submarine cables is to use the back-twist frame. Due to different production processes, the height requirements for the back-twist frame are different. Large-diameter submarine cables have higher requirements for the height of the back-twist frame, and large-diameter submarine cables are the future submarine cable field. The development trend, in order to meet the requirements of submarine cable untwisting, the height of the untwisting frame will be very high. It is relatively simple to install the untwisting frame that meets the requirements of submarine cable untwisting in the cable manufacturer, but the design ...
