Embodiment Construction

[0011] The present invention will be further described below in conjunction with 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 drive gear 8, a hydraulic motor 5, and the like.

[0013] The hydraulic turntable 2 is installed on the construction ship and may rotate forward and reverse. The entrance and exit 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 through the bearing plane bearing 4. The transmission internal gear 7 is fixedly installed under the base of the hydraulic turntable 2, and the transmission The driving gear 8 meshed with the internal gear 7 is fixed on the output shaft of the hydraulic motor 5 whose speed, torque and power can be adjusted steplessly, an...

Abstract

The invention relates to a cable turntable, which includes a hydraulic turntable installed on a construction ship and capable of rotating in forward and reverse directions, and a cable bridge whose inlet and outlet can be adjusted left, right, and up and down. The base of the hydraulic turntable is connected to the installation deck of the construction ship through bearing plane bearings. There is a transmission inner gear under the base of the hydraulic turntable. The driving gear meshing with the transmission inner gear is fixed on the hydraulic motor with stepless adjustment of speed, torque and power. On the output shaft of the hydraulic motor, the hydraulic motor is fixed on the fixed base of the installation deck. The maximum bearing capacity of the cable turntable is 1500 tons, and the outer diameter is 18 meters. The speed of the hydraulic turntable is continuously variable and the range is 0-0.063rad / s. The cable turntable adopts the untwisting method, which can not only satisfy the untwisting of submarine cables, but also solve the difficult problem of installation.

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 ...
