Detailed description of the invention
Illustrate detailed description of the invention of the present utility model below in conjunction with the accompanying drawings.
See Fig. 1, Fig. 2, crane based on suspension hook feedback of status of the present utility model disappear ornaments standby, including lifting machine
Structure 1, trolley body 2, control unit, converter, the side plate of lifting hook pulley group 1-1 of described lifting mechanism 1 is fixed with first
Sensor 4, spool shaft 1-2 is fixed with load loading component 5, and the top board of trolley body 2 is fixed with support 3, solid on support 3
Surely having the second sensor 6, described second sensor 6 is the encoder that hoists, and the encoder 6 that hoists is fixed with gear, and hoist coding
Gear on device 6 engages with the gear in spool shaft 1-2,
Angle signal for the inclination angle of monitoring suspension hook in real time and is passed to control unit by described first sensor 4, the
Two sensors 6 are for measuring the rope capacity transferred and length signals passing to control unit, and load loading component 5 is used for
Measure the weight of load and weight signal is passed to control unit；
Described control unit is for entering the weight signal of the angle signal of suspender, the length signals of steel wire rope and load
Row processes and output signal passes to converter, and converter regulates the voltage of motor according to the output signal of control unit.
Described first sensor is vertical reference or gyroscope.
Described control unit uses single-chip microcomputer or PLC.
Seeing Fig. 3, Fig. 3 is Frequency Converter Control voltage curve schematic diagram, and in figure, abscissa t represents the time that load hoists；
Vertical coordinate v represents the output voltage of motor；t0Representing rolling period front end identification point, the angle signal exported by gyroscope is true
Fixed, thus carry out periodically additional control；△ t represents the length in control cycle, by the length signals of the encoder output that hoists
Determining, l represents the length of steel wire rope, and l is the longest, and the cycle of △ t is the longest；M represents the weight of load, by load loading component
Recording, for determining that motor controls the amplitude of voltage, m is the biggest, and the amplitude controlling voltage is the biggest.By gyroscope, hoist volume
Code device and the output signal of load loading component, control unit can determine starting point that load starts to wave respectively, wave week
Phase and amplitude, such that it is able to dope the approximately periodic change curve of electric moter voltage regulation, converter can be according to doping
Electric moter voltage adjustment curve, motor is controlled in real time, thus the effect of the pendulum that reaches to disappear.
Fig. 4 be disappear pendulum before the range ability of dolly, speed, the analogous diagram of acceleration, Fig. 5 be disappear pendulum after dolly operation away from
From, the analogous diagram of speed, acceleration, Fig. 4, Fig. 5 carry out contrasting it can be seen that after the pendulum that disappears acceleration and the speed of trolley travelling bent
Line trends towards smoothing, and monkey is capable of steadily accelerating.Fig. 6 is the pendulum front steel wire rope relative angle emulation with dolly that disappears
Figure, Fig. 7 is the relative angle analogous diagram of steel wire rope and dolly after pendulum that disappears.Fig. 8 is suspension hook angle analogous diagram before the pendulum that disappears, and Fig. 9 is for disappearing
Pendulum rear hanger angle analogous diagram, Fig. 8, Fig. 9 carry out contrasting it can be seen that suspension hook angle shock range reduces, can be more effectively
Suppression load is waved.
Therefore, from simulation result it can be seen that after introducing suspension hook angle, the effect that system is run is improved, to pressing down
Load processed has waved positive effect in running, and monkey is capable of steadily accelerating, velocity and acceleration
Change and tend to smooth；The smooth transition in accelerator of rope traction angle, and suspension hook swing angle is also limited in more
Low level, load is waved and has been obtained effective suppression.Within the 60 seconds operation times set, system even running.
Finally should be noted that: it is only limited by above example in order to the technical solution of the utility model to be described
System；Although being described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the field should
Understand；Still detailed description of the invention of the present utility model can be modified or portion of techniques feature is carried out equivalent and replace
Change；Without deviating from the spirit of technical solutions of the utility model, it all should contain the technical scheme being claimed at this utility model
In the middle of scope.
