Embodiment
The utility model is made up of 12V DC power module 2, resistor 3, potentiometer 4, expansion module 5, communication cable 6.
Fig. 1 shows that door machine equipment electrical control cubicles power supply 1 is connected with 12V DC power module 2,12V DC power module 2
It is connected with resistor 3, the other end of resistor 3 is connected with potentiometer 4, and potentiometer 4 is connected with expansion module 5, extension
Module 5 is connected by communication cable 6 with the PLC module 7 of door machine control device.
Fig. 1 shows that PLC module 7 is connected with frequency converter 8, and frequency converter 8 provides output current, raising electricity to lifting motor 9
Machine 9 is connected by belt with hoisting drum 11, and brake 10 is connected on the output shaft of lifting motor 9, on hoisting drum 11
The steel wire rope of winding is connected with grab bucket 12, and driving grab bucket 12 carries out grasping manipulation.Frequency converter 8, lifting motor 9, brake 10,
Driving 12 operations of grab bucket of hoisting drum 11 are prior arts, and improvement of the present utility model is by the output current of frequency converter 8
Control reach to grab bucket 12 crawl amounts control.
The model of the 12V DC power module 2 of one embodiment of the present utility model is DR-75-12, the type of resistor 3
Number it is WX14-12 2K2, the model of potentiometer 4 is WX-050 2K2, and the model of expansion module 5 is PS7DS-50V8Y-L, PLC
The model of module 7 is CP-316H.
Fig. 2 shows that+the V of 12V DC power module 2 is wired to the 1st pin of resistor 3, and the 3rd pin of resistor 3 is wired to
3rd pin of potentiometer 4, the 2nd pin of potentiometer 4 are wired to the pin of expansion module 5 the 17th, the 1st pin and the 12V DC electricity of potentiometer 4
- the V of source module 2 is wired to the 18th pin of expansion module 5, finally connects expansion module 5 using communication cable 6 and PLC module 7 is entered
Row communication.
It is of the present utility model as follows using process：
The utility model installs a terminal block additional in PLC module 7 and provides analog input interface, joins in door machine drivers' cab
A potentiometer 4 is installed additional on the reserved place of dynamic platform, analog quantity is exported by adjusting knob, and rope power output is supported for adjusting
Square, scope are 0% -40%.Potentiometer 4 divides for 7 grades, be 1 grade to 7 grades, the bigger PLC module 7 of gear to support frequency converter 8 to
Upper torque is bigger, and the goods that grab bucket 12 captures when closing bucket and grabbing goods is fewer.
Running is as follows：
Grab bucket 12 is opened：Opening and closing rope declines at full speed, and supporting mechanism is motionless, and grab bucket 12 is opened.
Grab bucket 12 drops to stack：When grab bucket 12 with certain speed uniform descent for a period of time when, exported by frequency converter 8
The torque of current control lifting motor 9, when reaching certain torque, system controls the automatic retarding of lifting motor 9 until stopping, to protect
When stack is down in each grab bucket 12 of card, the elastic state of 4 steel wire ropes is essentially the same.In actual job, grab bucket 12 is grabbed every time
The position taken is that commander's work on ship determines.In this process, position is frequently necessary to adjust, and causes grab bucket 12 often to be slowed down
Or accelerate, the speed fallen every time in stack is all different.In this case so that lifting motor 9 is controlled by system every time
For automatic retarding when stopping, the elastic state of 4 steel wire ropes is all different.So to ensure that grab bucket 12 falls in stack every time
Speed all, it is necessary to whether detection grab bucket 12 is a period of time with certain speed uniform descent, if so, then system is transported
OK, if it is not, then this time grasping system is not run.
Grab bucket closure：During the closure of grab bucket 12（Start to capture goods）, opening and closing is restricted closes bucket at full speed, supports rope to be joined according to drivers' cab
The setting of the adjusting knob of potentiometer 4 on dynamic platform carrys out output torque.The setting of knob be driver according to the proportion of goods, oneself
Operating habit and operation process in constantly adjust.For example, when there is opening and closing bucket phenomenon again, driver can be adjusted
Rope output torque is supported in the knob increase of potentiometer 4, and that reduces grab bucket 12 takes depth, so as to reduce the crawl amount of grab bucket 12.
Vice versa.When grabbing bucket 12 closures to a certain extent, controlled motor brake 10 acts, and braking supports steel wire rope until grab bucket
12 close completely.The step is mainly the signal of sense weight sensor, and when reaching certain weight, brake 10 is automatic
Start to brake.After the closure of grab bucket 12, opening and closing supports rope to rise together.
The utility model has advantages below：
It is possible, firstly, to reduce the type and quantity of deposit grab bucket, realize and only meet operation using a kind of grab bucket of bucket capacity
The needs of different goods classes.The buying of grab bucket, storage, maintenance, the cost of management are reduced, while also eliminates part dangerous matter sources,
Reduce security risk.
Secondly, the crawl amount of grab bucket is controlled compared to the individual skill and operating experience that currently rely primarily on operating personnel,
The utility model can reduce the requirement of machine operating personnel technology and experience on the door, help different drivers all with same standard
Mode operation, the operating efficiency of the horizontal relatively low driver of operation can substantially reach average operation efficiency.
3rd, the utility model is simple to operate, and conversion is convenient, and control crawl amount only needs the gear of driver's rotation potentiometer to open
Pass.
4th, safety coefficient can be improved.For the different goods of proportion, door machine is during crawl all without surpassing
The phenomenon of load.
