Wave-compensated winch device with pneumatic lifting

Abstract

The invention relates to a wave-compensated winch device with pneumatic lifting. The device comprises a box body, a motor, a motor shaft, a motor gear, a heavy hammer, a heavy hammer shaft, a heavy hammer gear, a transmission gear shaft, a first bearing, a speed limiting device, a clutch device, a first transition shaft, a first transition main gear, a first transition slave gear, a reel, a reel shaft, a reel gear, a manual shaft, a manual gear, a lever shaft, a lever sliding gear, a lever slave gear, a lever device and a wave-compensating hydraulic motor; the device is characterized by further comprising a pneumatic rotating shaft, a pneumatic main gear, a pneumatic slave gear, a fixed seat, a fixed cover, a motor seat, a turntable, a pneumatic motor, a motor transmission gear, a motor driven gear, a motor driven shaft, a transmission sleeve, an one-way bearing, a roller type overrunning clutch, a second bearing, a third bearing, an outer ring pin and a turntable pin; after the leverslave gear is rotatably connected with the pneumatic slave gear, the motor is started to achieve the lifting of a lifeboat. The device has the advantages that a rescue boat can be pneumatically liftedin an emergency situation, and the rescue boat is quickly and safely hoisted back to a ship.

Description

technical field [0001] The invention relates to a lifting device for a rescue boat, in particular to a wave compensating winch device with pneumatic lifting. Background technique [0002] At present, the winch device for raising and lowering the rescue boat includes a box body, a motor, a motor shaft, a motor gear, a weight, a weight shaft, a weight gear, a transmission gear shaft, a first bearing, a speed limiting device, a clutch device, a first transition shaft, First transition master gear, first transition slave gear, reel, reel shaft, reel gear, manual shaft, manual gear, lever shaft, lever sliding gear, lever slave gear, lever device and surge hydraulic pressure Motor; the motor shaft is set in the box, the motor gear is fixed on the motor shaft, the motor is connected to one end of the motor shaft, the weight shaft is set on one side of the motor shaft, the weight gear is fixed on the weight shaft, the weight gear is connected to the motor Gear transmission connecti...

AI Technical Summary

Problems solved by technology

[0003] The winch device of the lifting rescue boat only has two methods of manual lifting and motor lifting when lifting the rescue boat. When the marine environment is harsh, it may not be possible to supply power to the motor and the personnel cannot perform manual operations on the deck. It is impossible to lift the rescue boat at sea in time, which increases the danger of the rescue boat at sea
