Abstract
The invention discloses a winch for a ship unloader. The winch comprises a main motor and a winding drum. An output shaft of the main motor is provided with a high-speed shaft brake and is in transmission connection with a speed reducer, an output shaft of the speed reducer is provided with a first clutch and is in transmission connection with one end of the winding drum, the other end of the winding drum is in transmission connection with a spare gear motor, both the spare gear motor and the main motor are electrically connected with a controller, an output shaft of the spare gear motor is provided with a second clutch, a winding drum brake is installed on the winding drum and controlled by the controller, the output shaft of the main motor is provided with a speed sensor, and the speed sensor is electrically connected with the controller. According to the winch for the ship unloader, due to the fact that the spare gear motor is additionally arranged, when the main motor breaks down, normal running of the main motor can be still ensured; in addition, due to the fact that the high-speed shaft brake and the winding drum brake are arranged, the safety performance of the winch is effectively improved, and the structure is simple and easy to achieve.
Description
Technical field
The present invention relates to a kind of ship unloaders, relate in particular to a kind of ship unloaders winch.
Background technology
Ship unloaders are to utilize continuous conveyor to make the head that can promote bulk granular material, or have reclaiming capacity voluntarily concurrently, or be equipped with feeding, drawing-in device, bulk granular material is continuously proposed to cabin, be then unloaded to jib or frame and can be transported to the special-purpose machinery that the defeated place of bank master send machine system to go.Winch is one of important component part of ship unloaders, at present, the winch that ship unloaders adopt adopts single driven by motor mostly, once motor breaks down, transport and can only interrupt, need, after electrical machmary maintenance is good, just can work on, thus, greatly reduce the work efficiency of ship unloaders, and the winch of existing ship unloaders only adopts single drg braking mostly, and braking effect is poor, has certain potential safety hazard.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of ship unloaders winch is provided, adopt single driven by motor to solve existing ship unloaders winch, once break down, need after electrical machmary maintenance is good, just can work on, affect the problem of work efficiency, and existing ship unloaders adopt the braking of single drg with winch, have the problem of potential safety hazard.
The object of the invention is to be achieved through the following technical solutions:
A kind of ship unloaders winch, comprise main motor and reel, high speed shaft drg is installed on the output shaft of described main motor, and output shaft and the retarder of main motor are in transmission connection, on the output shaft of described retarder, first clutch is installed, and the output shaft of retarder and one end of reel are in transmission connection, the other end of described reel and reducing motor for subsequent use are in transmission connection, described reducing motor for subsequent use, main motor is all electrically connected with controller, and on the output shaft of reducing motor for subsequent use, second clutch is installed, on described reel, drum brake is installed, described drum brake is by controller control, on the output shaft of described main motor, speed sensor is installed, described speed sensor and controller are electrically connected.
As preferred version of the present invention, described high speed shaft drg is magnet stopper.
As preferred version of the present invention, described main motor is with motor protecter.
As preferred version of the present invention, described drum brake is hydraulic-driven, on its oil circuit, electromagnetic valve is installed, and described electromagnetic valve and controller are electrically connected.
As preferred version of the present invention, described controller is PLC controller.
Beneficial effect of the present invention is that described ship unloaders, make in the time that main motor is out of order by setting up reducing motor for subsequent use with winch, still can ensure normal operation, and by high speed shaft drg and drum brake are set, effectively improved safety performance, simple in structure, be easy to realize.
