Description
Technical field
This utility model design winch for ship, is specifically related to a kind of identical tension winch for ship.
Background technology
Ship winch is ocean operation boats and ships and the topmost equipment of shipping boats and ships, owing to using when its major function is exactly dilatory, mooring under complicated marine environment, location, a kind of can automatically control cable tension, the constant tension winch of speed increasingly receives publicity, particularly there is actual application value widely at crane ship, barge, cross sliding type dredger, pipe laying barge and ocean platform and other boats and ships, have become as one of important equipment of current deck machinery.Constant tension winch carries out the location of boats and ships as " anchoring " winch and time power fixes on boats and ships, and sometimes under severe ocean condition, ship's fix is abnormal the most difficult, has even been difficult to.The motion of whole boats and ships produces huge inertia force and drag force, the even up to Fracture Force of steel wire rope steel to winch cable, thus occurs that the dangerous situation of disconnected cable occurs.What the most most of constant tension winches were commonly used is motor or hydraulic motor directly drive reductor; often there is motor or hydraulic pressure horse rotating the most frequently work in that control model, and motor or the bearing of hydraulic motor and output shaft are had the biggest infringement；Particularly to the injury of motor to life, because motor is the need for the halted state of a short time at rotating working copy, and in the constant tensile control of ship winch, it is also instantaneous that the boats and ships that wave causes rise and fall, and what constant tension winch such as can not be in good time reacts it is possible to the major accident of cable breaks can be caused.
Summary of the invention
The purpose of this utility model is to provide the winch for ship of a kind of identical tension.
The technical scheme that this utility model is taked is:
A kind of constant tension winch peculiar to vessel, including motor, reduction box, reel and chock, described motor via reducer drives reel, on reel, volume has hawser, hawser cross-under chock, also include constant tension control system, described constant tension control system includes magnetic powder cluth, device for measuring force and PLC, described magnetic powder cluth is installed between the output of motor and the input of reductor, described device for measuring force is three roller shaft pin device for measuring force, described three roller shaft pin device for measuring force include three rollers being distributed in isoceles triangle, the rotating shaft of intermediate roller is axial pin type force cell, in the rotating shaft of one roller of described both sides, encoder is installed, described three roller shaft pin device for measuring force are arranged between reel and roller navigator, described hawser exports after sequentially passing through three rollers after chock commutates；Described PLC controls device wind and does not controls to connect in motor, axial pin type force cell, encoder and magnetic powder cluth.
Further, described PLC control device includes PLC, signal processor, relay and touch screen.
Further, described reel is provided with Manual brake device.
One according to claim 1 constant tension winch peculiar to vessel, it is characterised in that described motor is frequency conversion braking motor.
Yet further, described chock is five post chocks.
After taking above technical scheme, the beneficial effects of the utility model are:
Between motor and speed reducer, add magnetic powder cluth reduce the spoilage of motor or hydraulic motor；When tension force instantaneous excessive time, need not start motor or hydraulic motor, the moment of torsion having only to reduce in time magnetic powder cluth produces coaster by magnetic powder cluth, cable reel can produce under the pulling force effect of hawser puts rope torque, thus efficiently solves the situation needing motor reversal ability cable laying rope；When automatic constant tension works, frequency conversion motor is substantially in one direction operating of low speed, and even in halted state, whole control has the PLC feedback according to signal, automatically controls work timely and effectively.Greatly reduce the damage frequency of motor, meanwhile, and big saved ship energy, through primary Calculation, electric power energy about 40% can have been saved with the constant tension winch of our this configuration.And being of wide application of our this winch, the multipoint positioning of boats and ships, mooring, the displacement of engineering ship, port and pier are to stevedoring operations, the location etc. of ocean platform.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described:
As shown in the figure, a kind of electronic constant tension winch, including winch pedestal, for jinny, motor 1, reduction box 2 and reel 4 are installed on pedestal, motor 1 is frequency conversion braking motor, described motor 1 drives reel by reductor 2, the output shaft of motor 1 is provided with magnetic powder cluth 3 with the input between centers of reductor 2, on reel 4, volume has hawser 6, reel 4 to be to store hawser and connect the device of load, and hawser 6 number of plies is more than three layers, automatic cable arrangement device can be added, it is ensured that cable arranging is neat before reel.Reel is provided with Manual brake device 8.Hawser 6 can be nylon rope or steel wire rope, arranges according to load request.Hawser exports after sequentially passing through three roller shaft pin device for measuring force 7 and chock 8, described three roller shaft pin device for measuring force include three rollers 71 being distributed in isoceles triangle, the rotating shaft of intermediate roller is axial pin type force cell 72, in the rotating shaft of one roller of described both sides, encoder 73 is installed, encoder 73 is incremental bidirectional speed encoder, prime roller shaft one end that incremental bidirectional speed encoder is arranged in three rollers, this grade of roller shaft rotates together with roller, it is fixing that encoder 73 uses hollow axle to be connected with roller shaft, encoder 73 is outer uses protective cover protection, guarantee not by external impacts.The outfan of three roller shaft pin device for measuring force is provided with two vertical rollers 74, and hawser is guided or commutation by roller.
Motor 1, magnetic powder cluth 3, axial pin type force cell 72 and encoder 73 are all connected with PLC, and described PLC controls device and includes PLC, signal processor, relay and touch screen.
After the steel wire rope of winch or hawser pass three roller shaft pin device for measuring force, axial pin type force cell is as the axle of a middle roller, tension force suffered on steel wire rope or hawser is transferred to PLC by axial pin type force cell, by PLC by calculating the pulling force on hawser:
T=F/2cos
In formula: the power that F force cell records
The pulling force of T hawser
The angle of α hawser.
By the automatic calculating of PLC, the touch screen display of control system is exactly hawser real-time pulling force numerical value, PLC is contrasted by the control numerical value of Automatic Program with user setup simultaneously, and output in real time controls magnetic powder cluth and motor (or driving electro-hydraulic proportional valve of hydraulic motor).
Simultaneously, the speed of hawser, length signals are transferred to PLC by encoder on the another one roller shaft of three roller device for measuring force in time, this signal through routine processes, with real-time speed and length with display hawser, and can be controlled speed and the length of winch folding and unfolding hawser by PLC.
