Abstract

The invention discloses a friction winch and belongs to the technical field of marine machinery. The friction winch comprises a support, a first installing shaft, a second installing shaft, a first coiling block, a second coiling block, a power mechanism and a cable pressing assembly which comprises a third coiling block; the axes of the first coiling block, the second coiling block and the third coiling block are parallel to one another; and at least part of the third coiling block is located between two common tangent planes of the first coiling block and the second coiling block, when a cable is wound, the portion, located between the first coiling block and the second coiling block, of the cable can be pressed to the plane where the axis of the first coiling block and the axis of the second coiling block are located through the third coiling block, the contact area between the cable and the first coiling block as well as between the cable and the second coiling block is increased, and therefore the friction force of the coiling blocks on the cable is increased, the cable winding circle number can be reduced, the lengths and the diameters of the coiling blocks are reduced, the volume of the friction winch can be reduced easily, and the deck space occupied by the friction winch is reduced.

Description

technical field [0001] The invention relates to the technical field of marine machinery, in particular to a friction winch. Background technique [0002] The friction winch is usually used to assist the cable winch on the ship to take in and out the cable. Usually, after the cable is released from the cable winch, it will be wound several times on the friction winch and then connected to the weight, so that the weight produced by the weight The pulling force of the friction winch acts directly on the friction winch, not directly on the cable winch, so that the cable winch can be prevented from being subjected to a large pulling force. Due to the existence of the friction winch, there is still a certain tension on the section of the cable that is involved in the cable winch, so that the problem of chaotic arrangement of the cables on the reel of the cable winch can be avoided. [0003] The existing friction winch mainly includes a bracket and two parallel drums arranged on t...
