Description
Technical field
The present invention relates to a kind of motor control technology field, be specifically related to a kind of with load limit and the hawser electronic anchor winch from tensioning function.
Background technology
Along with the continuous progress of electrical technology, electronic anchor winch, with the advantage of its uniqueness, is subject to the favor of numerous shipowners, user day by day, not only plays the effect of energy-conserving and environment-protective, also space windlass cabin and steering engine room originally can being installed Hydraulic Pump group saves, and can also alleviate the work capacity in shipbuilding yard.
Anchor winch winch hawser of the prior art is by being arranged on by shaft pin sensor between two gears (as shown in Figure 3) from tensioning, such structure dynamometry is larger by fluctuation ratio, in order to realize more accurate load limit function, separately torque force limiting device need be installed, so, motor must use floor type, and mounting structure is also inconvenient.
Summary of the invention

Detailed description of the invention
The electronic anchor winch of one as shown in figures 1 and 3 hawser is from tensioning and load limit mounting structure figure, comprise anchor winch body, anchor winch body comprises two winches and windlass, one of them winch of anchor winch is connected with drop-gear box 1, force transducer 9 is provided with in outer bearing 8 end of drop-gear box 1 transmission shaft 7, described transmission shaft of reduction box 7 is also connected with gear, and described gear is connected with motor 6 by imput shaft.
The automatically controlled dynamometry principle schematic of electronic anchor winch as shown in Figure 2, wherein the output signal of force transducer 9 is connected to change and veers away Iarge-scale system 10, the veer away output signal of Iarge-scale system 10 of described change is connected to the input end of the analogue collection module 11 in electric-control system 13, analogue collection module 11 is also electrically connected with PLC control module 12, the port of PLC control module 12 is also connected with rotating forward, reversion, motor overload, load controls, automatic cable laying value corrects and automatic take-up value correcting motor driving circuit, this motor-drive circuit is connected with motor 6, just control motor, reversion, load is stopped and is stopped waiting operation.
The structural representation of original technology as shown in Figure 4.Between the bearing 3 shaft pin sensor 4 being arranged on two gears 2, such structure dynamometry is larger by fluctuation ratio, hawser is also unstable from tensioning function, in addition in order to realize load limit function, need separately torque force limiting device 5 to be installed, so, motor 6 must use floor type, and mounting structure is also inconvenient.
Under normal circumstances; this electric-control system can realize the receiving/releasing cable function of anchor winch; when load is greater than set load limit value; system meeting automatic shutdown circuit; thus the safety of protection anchor winch equipment own; this also instead of old-fashioned torque force limiting device form, has simplified the mechanical mechanism of equipment.
When opening after tensioning function, now motor positive and inverse dictate operating system lost efficacy, whether the action of motor is controlled by the size of load force F on hawser completely, if now during F> automatic cable laying power setting value f, motor can automatically perform cable laying function, during F < automatic take-up power setting value f, motor can automatically perform take-up function.In addition, in automatic receiving/releasing cable power setting value problem, due to Long-Time Service or other factor cause sensor performance that skew occurs time, we add a set of auxiliary fine adjustment function in original control system, can allow client more convenient correction receiving/releasing cable setting value f at the scene.
