Description
Technical Field
The utility model belongs to the technical field of marine winch equipment, concretely relates to marine multi-operating mode auto-change over device for winch.
Background
The marine winch has wide application, and can be used in various occasions such as anchoring positioning, traction and towing, hoisting and swing stopping and the like. Generally, the working condition of a winch is single, but along with the development of marine technology, the integration level of ship equipment is higher and higher, and the working condition that traditional winch faces is also more and more complicated.
The design that current winch operating mode switched generally adopts manual dog clutch, and functional structure is simple, and manual dog clutch can not throw off with the load when meetting emergency (need earlier the stopper braking, make the clutch not bear the load, and the machine just can throw off the clutch in the reversal slightly, loosens the stopper again, just can realize emergent release), and degree of automation is not high. .
SUMMERY OF THE UTILITY MODEL

The utility model provides a marine multi-operating mode auto-change over device for winch, which comprises a main shaft, the first spline housing in a left side, left side second spline housing, the friction disc, the first spline housing in the right side, right side second spline housing, hydraulic piston cylinder and binary channels rotary joint, the main shaft is installed on winch base or support, the first spline housing in a left side, left side second spline housing, cup joint on the main shaft after right side first spline housing and right second spline housing connect gradually, the friction disc is installed in the spline housing, the continuous empty cover of right side first spline housing and right second spline housing is on the main shaft, one end is connected with the friction disc, its other end passes through the external splines and is connected with decelerator, hydraulic piston cylinder installs in right side second spline housing and left second spline housing, the one end at the main shaft is installed to the binary channels rotary joint, fix on base or support through arresting gear.
As a further technical proposal of the utility model, the friction plate is a copper-based friction plate, an outer friction plate and an inner friction plate.
Furthermore, hydraulic oil enters the oil hole of the main shaft through the multi-channel rotary joint and is independently transmitted to the hydraulic piston cylinder through each channel.
Furthermore, a chamber for installing a hydraulic piston cylinder is arranged on the right second spline sleeve and the left second spline shell.
Further, the main shaft and the multi-channel rotary joint are on the same central line.
The utility model has the advantages that,
1. the design requirement of a single winch on complex working conditions can be met;
2. the emergency release function of the steel wire rope during loading can be realized;
3. the axial dimension of the winch is shortened.
