Three-roller purse seine winch

Abstract

The invention discloses a three-roller purse seine, which comprises a rack, three roller assemblies and rope arrangement assemblies which respectively correspond to the three roller assemblies. The three roller assemblies are in a step arrangement. Each roller assembly comprises a hydraulic motor, a roller body, a transmission shaft, a brake, a speed reducer and a clutch, wherein the transmission shaft is coaxially arranged in the roller body; the input shaft and the output shaft of the speed reducer are coaxial; the speed reducer and the clutch are respectively arranged at both ends of the interior of the roller body; the brake is arranged between the hydraulic motor and the speed reducer; one end of a shell of the brake is fixedly connected with the rack; the other end of the shell of the brake is fixedly connected with the shell of the speed reducer; the input shaft of the speed reducer passes through the brake to be connected with the output shaft of the hydraulic motor in the manner of transmission; one end of the transmission shaft is connected with the output shaft of the speed reducer in a transmission manner; the other end of the transmission shaft is connected with one end of the clutch in a transmission manner and is supported on the stand in a rolling manner; the other end of the clutch is fixedly connected with the roller body, so that the roller body and the transmission shaft are connected in a separation and union manner; and both ends of the roller body are connected with the rack in a rolling manner. The three-roller purse seine winch disclosed by the invention is compact in structure, stable and reliable in operation and long in service life.

Description

technical field [0001] The invention relates to a seine winch for a fishing vessel, in particular to a three-drum seine winch for an ocean-going fishing vessel. [0002] Background technique [0003] At present, there is a broad market prospect for the application of domestic ocean-going fishing boats, but the matching winch occupies a large deck area of ​​the fishing boat, the transmission structure has poor lubrication conditions, the lubricating oil easily pollutes the surrounding environment, and the labor intensity of the workers is high. And other issues. [0004] The date of the authorization announcement is 2011.08.03, the authorization announcement number is CN 201911196 U, and the Chinese patent document titled "A Three-Drum Seine Winch for Ocean Fishing Vessels" discloses a three-drum seine winch, which "includes a ladder-shaped arrangement The main drum assembly, the front drum assembly and the drag drum assembly, the wire ropes of the front drum, the main drum...

AI Technical Summary

Problems solved by technology

"Because in terms of transmission, the patent simply changes the open gear transmission to a closed gear transmission. The transmission route between the input shaft of the gearbox and the output shaft of the motor, the output shaft of the gearbox and the drum, and the installation structure of the gearbox There is no essential change, the offset between the axis of the output shaft of the hydraulic motor and the axis of the drum is large, and the problem of occupying a large deck area of ​​the fishing boat cannot be fundamentally solved, and the stability and reliability of the transmission are poor
