Problems solved by technology

At present, most constant tension winches on the market generally use motors or hydraulic motors to directly drive the reducer. In that control mode, the motor or hydraulic horse often works in forward and reverse directions very frequently in a short period of time. Bearings and output shafts have great damage; especially the damage to the mot

Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

[0016] As shown in the figure, an electric constant tension winch includes a winch base for fixing the winch. A motor 1, a reduction box 2 and a reel 4 are installed on the base. The motor 1 is a variable frequency brake motor, and the motor 1 The reel is driven by the reducer 2. A magnetic powder clutch 3 is installed between the output shaft of the motor 1 and the input shaft of the reducer 2. The reel 4 is wound with a cable 6. The reel 4 is a device for storing the cable and connecting the load. The cable 6 If the number of layers exceeds three, an automatic cable discharge device can be added in front of the drum to ensure that the cables are arranged neatly. The reel is provided with manual braking device 8. Cable 6 can be a nylon rope or a steel wire rope, which is set according to load requirements. The cables pass through the thre...

Abstract

The invention relates to a marine constant-tension winch. The marine constant-tension winch comprises a motor, a reduction gearbox, a winding drum and a fair-lead. The motor drives the winding drum through the reduction gearbox. A mooring rope is wound on the winding drum and connected with the fair-lead in a penetrating mode. The marine constant-tension winch further comprises a constant-tension control system. The constant-tension control system comprises a magnetic powder clutch, a force measuring device and a PLC. The magnetic powder clutch is installed between the output of the motor and the input of the reduction gearbox. The force measuring device is a three-roller shaft pin type force measuring device. The three-roller shaft pin type force measuring device comprises three rollers distributed in the shape of an isosceles triangle. A rotary shaft of the middle roller is a shaft pin type force measuring sensor. An encoder is installed on a rotary shaft of one of the rollers arranged on the two sides. The three-roller shaft pin type force measuring device is arranged between the winding drum and the fair-lead. The mooring rope sequentially penetrates through the three rollers and then is reversed through the fair-lead to be output. A PLC control device is in control connection with the motor, the shaft pin type force measuring sensor, the encoder and the magnetic powder clutch.

Description

technical field [0001] The invention designs a marine winch, and in particular relates to a constant tension marine winch. Background technique [0002] The ship winch is the most important equipment for marine operation ships and cargo ships. Because its main function is to use it for dragging, mooring and positioning in complex marine environments, a constant tension winch that can automatically control the tension and speed of cables is becoming more and more It has attracted attention, especially in crane ships, barges, traversing dredgers, pipe-laying ships, and offshore platforms and other ships have extensive practical application value, and has become one of the important equipment of deck machinery at present. When the constant tension winch is used as an "anchor" winch on a ship for positioning and dynamic fixing of the ship, sometimes under harsh sea conditions, the positioning of the ship is extremely difficult or even difficult to complete. The movement of the ...
