Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The three-drum friction double-configuration windlass is to generate tension by winding the steel wire rope with two front-end drums for multiple turns, and the rear storage drum is used to store the wire rope, which is called three-drum. Double configuration, so it is called three-drum friction double configuration windlass.

As shown in Figure 1, the structure of the three-drum friction double-configuration windlass of the present invention is to include a set of front drums 1 and a set of rear drums 10 respectively arranged on both sides, each set of front drums 1 and rear drums 10 There are belt brakes 11 respectively installed on each set of front drum 1 and rear drum 10 respectively provided with a large gear 2 with the same structure, and the two large gears 2 on each side are meshed with the pinion 3 for transmission connection at the same time, the pinion 3, The jaw clutch 4 and the reduction box 5 are coaxially connected sequentially. The two output shafts of the reduction box 5 are connected to the safety disc brake 6 and the water-cooled disc brake 7 respectively. The third output shaft of the reduction box 5 is additionally passed through a drum The gear coupling 8 is connected with the motor 9 transmission; the front drum 1 and the rear drum 10 are wound with a wire rope 12, one end of the wire rope 12 is connected with the anchor, and the other end of the wire rope 12 stretches into the storage winch 13 and is fixedly connected.

Each jaw clutch 4 adopts a cylinder control structure, and the left and right jaw clutches 4 are interlocked through the control system, and the two jaw clutches 4 cooperate to engage and disengage, so that the power energy is transmitted to the two jaw clutches respectively. The sets of actuators respectively carry out the retraction and release of the anchors.

Reduction box 5 adopts two-stage or multi-stage structure. The reduction box 5 is respectively equipped with a safety disc brake 6 and a water-cooled disc brake 7 at one end of the output shaft and one end of the intermediate shaft, which are respectively used for stopping when the motor 9 or mechanical components fail during the working process of the windlass, and when the anchor is lowered. The control of medium transmission speed prevents the lowering speed from being too fast. The intermediate shaft of reduction box 5 can choose to install the brake of water-cooled disc brake 7 structure, air-cooled disc brake or other forms.

Motor 9 selects forms such as AC frequency conversion, DC motor or hydraulic motor for use. The band brake 11 uses a hydraulic cylinder to implement tensioning and loosening between the brake band and the brake hub. The band brake 11 is used to lock the windlass after the anchor is lowered to a predetermined position on the seabed, and the static anchor is performed after the anchor is accurately positioned. brakes, or other forms of braking, to achieve the purpose of safe work. The wire rope 12 is wound around the front drum 1 and the rear drum 10 to generate wire rope tension, and the storage winch 13 is used for storing the wire rope.
