Embodiment Construction
[0017] As shown in Figures 1 and 2, sliding bearings I2 and II3 are set on the upper support 1, and sliding bearings V17, IV18 and bearing VI15 are set on the lower support 12. The sliding bearings V17, IV18 are in transmission cooperation with the bearing VI15, and the gap formed between them makes the bearing VI15 have a certain swing during transmission. Since the fairlead device has been placed in seawater for a long time, in order to prevent rust, the above-mentioned sliding bearings are all made of engineering plastic alloy.
[0018] The pulley frame 4 is fixed between the upper support 1 and the lower support 12, and the pulley 5 is supported on the pulley frame 4 through the pulley mandrel 19, and is connected with the sliding bearing III6. In order to prevent seawater from corroding the pulley mandrel 19, the material of the pulley mandrel is made of 2Cr13. The outer edge of the pulley 5 is provided with a groove 7, and a steel wire rope 9 is wound in the groove 7. ...

The invention discloses an underwater leadfair of a mooring winch, which consists of an upper support saddle, a lower support saddle, a pulley bracket body and a pulley, wherein the upper support saddle is sleeved with two sliding bearings I and II, and a bearing VI sleeved on the lower support saddle is in transmission fit with the two sliding bearings V and IV; the pulley bracket body is connected between the upper and lower support saddles; the pulley is supported on the pulley bracket body through a pulley mandrel; a wire cable is wound on the pulley; one end of the pulley bracket body isfixedly connected with the bearing VI, clamped with a connecting plate by a nut and positioned by a pin roll; and a baffle plate is welded under the pulley. The underwater leadfair can ensure to operate normally under unobservable condition, and material selection of parts overcomes the difficulty that key parts of the leadfair are easily corroded by seawater and rusty.
Description
technical field [0001] The invention relates to a mooring winch, in particular to an underwater cable guiding device for a mooring winch which can effectively prevent steel ropes from jamming, resist corrosion, prevent rust and facilitate maintenance. Background technique [0002] The fairleads of ordinary mooring winches on the market are usually installed on the deck, and their working status can be observed intuitively, but the deck fairleads are not suitable for mooring automatic positioning systems of offshore operating platforms, and Its key parts are not corrosion-resistant and easy to rust. Contents of the invention [0003] The invention provides an underwater cable guide device which can effectively prevent the steel rope from jamming, is corrosion-resistant, rust-proof, and is convenient for maintenance. [0004] In order to solve the above technical problems, an underwater cable guide device for a mooring winch of the present invention is composed of upper and...
