Description
Technical field
The present invention relates to a kind of safe anti-falling hook control system and method.
Background technology
Mechanical stereo garage is the one of parking apparatus, belongs to one of special equipment product, is divided into lifting cross-sliding type, vertical-lifting, horizontal mobile, Vertical Circulating, Simple lifting, multilayer cycling, AisleStack mechanical type etc. by its structure.
At present in the control system of mechanical three-dimensional parking device, the action of safe anti-falling hook controls by being elevated electronic control contactor, namely after the control contactor work of elevating motor, first make the work of safe anti-falling hook, after the normal work of safe anti-falling hook, then connect the power supply of elevating motor.Safety when such working method can ensure Transport Vehicle, but safe anti-falling hook is in open mode in the lifting process of motor, and in fact safe anti-falling hook only needs action before vehicle-containing leaves traversing framework can meet the service requirement of vehicle-containing always.The work of safe anti-falling hook continuous print not only can increase the consumption of electric energy, and can greatly reduce its application life, brings potential faults to the normal operation in garage.When the number of plies in garage is not high (as two, three layers), the duration of runs of elevating motor is not long, and the time of safe anti-falling hook continuous operation is not long; If but during the number of plies in garage very high (as five, six layers even higher), the time of safe anti-falling hook continuous operation will extend greatly.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of safe anti-falling to link up with control system and method, control simple, reliability is high, stable, greatly reduces the working time of safe anti-falling hook, extends the application life of safe anti-falling hook.
The object of the invention is to be achieved through the following technical solutions: a kind of safe anti-falling hook control system, it comprises power supply relay, safety hook control loop that at least one is parallel with one another, described safety hook control loop comprises the lifting motor contactor and safety hook coil of connecting successively, power supply is connected with elevating motor contactor by power supply relay, and elevating motor contactor is connected with safety hook coil.
Described safety hook coil obtains the electric safety hook that makes and opens.
It also comprises PLC, and power supply relay is connected with the control signal output of PLC.
A kind of safe anti-falling hook control method, is characterized in that: it comprises the following steps:
S1: vehicle-containing declines, and it comprises following sub-step:
S11:PLC controller controls power supply relay and lifting motor contactor closes, and safety hook coil obtains electric, and safety hook is opened, vehicle-containing setting in motion;
S12: if vehicle-containing is in safety hook scope of activities, then remain unchanged; If vehicle-containing is not in safety hook scope of activities, then PLC controls power supply relay disconnection, safety hook coil losing electricity, and safety hook is closed;
S2: vehicle-containing rises, and it comprises following sub-step:
S21: lifting motor contactor closes, vehicle-containing setting in motion, if vehicle-containing is in safety hook scope of activities, PLC controls power supply relay and closes, and safety hook coil obtains electric, and safety hook is opened; If vehicle-containing is not in safety hook scope of activities, vehicle-containing continues to rise;
S22: put in place if vehicle-containing rises, then PLC controls power supply relay and the disconnection of lifting motor contactor, safety hook coil losing electricity, and safety hook is closed, and vehicle-containing stops rising; Otherwise vehicle-containing continues to rise.
The invention has the beneficial effects as follows:
(1) safe anti-falling hook just works close to during its working range at vehicle-containing, under the prerequisite ensureing device security running, greatly reduces its conduction time, energy conservation, effectively improves the application life of safe anti-falling hook.
(2) for available circuit, this circuit merely add a control relay, takies the port of a PLC, and without the need to doing any change to existing safe anti-falling hook, improvement cost is cheap.
(3) adopt PLC to control, powerful, reliability is high, adds safety factor.

Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, a kind of safe anti-falling hook control system, it comprises power supply relay 1, safety hook control loop that at least one is parallel with one another, described safety hook control loop comprises the lifting motor contactor 2 and safety hook coil 3 of connecting successively, and power supply is connected with safety hook control loop by power supply relay 1.
Described safety hook coil 3 obtains the electric safety hook that makes and opens.
It also comprises PLC, and power supply relay 1 is connected with the control signal output of PLC.
A kind of safe anti-falling hook control method, is characterized in that: it comprises the following steps:
S1: vehicle-containing declines, and it comprises following sub-step:
S11:PLC controller controls power supply relay 1 and lifting motor contactor 2 closes, and safety hook coil 3 obtains electric, and safety hook is opened, vehicle-containing setting in motion;
S12: if vehicle-containing is in safety hook scope of activities, then remain unchanged; If vehicle-containing is not in safety hook scope of activities, then PLC control power supply relay 1 disconnects, safety hook coil 3 dead electricity, and safety hook is closed;
S2: vehicle-containing rises, and it comprises following sub-step:
S21: lifting motor contactor 2 closes, vehicle-containing setting in motion, if vehicle-containing is in safety hook scope of activities, PLC controls power supply relay 1 and closes, and safety hook coil 3 obtains electric, and safety hook is opened; If vehicle-containing is not in safety hook scope of activities, vehicle-containing continues to rise;
S22: put in place if vehicle-containing rises, then PLC control power supply relay 1 and lifting motor contactor 2 disconnect, safety hook coil 3 dead electricity, and safety hook is closed, and vehicle-containing stops rising; Otherwise vehicle-containing continues to rise.
The course of work of the present invention:
As shown in Figure 2, power supply relay 1 is connected in the control loop that power supply and safe anti-falling link up with, its duty is controlled by PLC, when vehicle-containing declines, PLC controls power supply relay 1 and works with elevating motor contactor 2 simultaneously, safety hook coil 3 obtains electric, the energising of safe anti-falling hook is opened, vehicle-containing lands smoothly, when vehicle-containing decrease beyond the working range of safe anti-falling hook, the work of PLC cutting-off controlling power supply relay 1, makes safe anti-falling link up with dead electricity and resets, thus the effective conduction time reducing anti-fall hook.
As shown in Figure 3, when vehicle-containing rises, elevating motor contactor 2 works, but does not work due to power supply relay 1, safety hook coil 3 no power, when the working range that vehicle-containing is linked up with close to safe anti-falling, PLC controls power supply relay work, switches on power, and safety hook coil 3 is obtained electric, by safe anti-falling opening of hook, enable vehicle-containing increase smoothly and put in place.
