In sealing in the manual control circuit of headstock gear electric control loop respectively.Manual control circuit in gate opening/closing control system
One redundancy protecting loop is set, to improve safety coefficient of the equipment under manual controlled state, waste of human resource is reduced.
Open and close redundancy protecting loop to be selected by the normally closed node of mechanical limit switch, the normally closed node of K05 and K06 relays and manual control mode
Select switch to be composed in series.Redundancy protecting loop is ahead of mechanical limit switch protection act, realizes the double defencive functions of control manually,
Improve reliability and the safety of operation.
Used as a kind of embodiment, also including alarm circuit, described alarm circuit is connected with Programmable Logic Controller；Gate
Position is detected by jaw opening sensor, and is input to Programmable Logic Controller in real time；Gate is sent by Programmable Logic Controller after in place and is reported
Alert signal reaches the purpose for reminding operator to note to alarm circuit, buzzer buzzing warning.After buzzer warning, when existing
Field operator does not shut down always（Stop gate opening/closing）, Programmable Logic Controller can the normally closed section of delays time to control K05 and K06 relay
Point disconnects, and realizes autostop, plays a protective role.
As a kind of embodiment, also including hand resetting button, described hand resetting button and Programmable Logic Controller
Connection, used as the input signal of Programmable Logic Controller, behind the position that reaches capacity, alarm circuit is reported to the police；Involution button is artificially pressed,
Programmable Logic Controller receives slot signal, and control alarm circuit disconnects, and reaches the purpose of noise reduction.
Components and parts required for control loop are using existing device in former control system.K05 and K06 relays are outputed a little
Standby, aperture measurement and control instrument, jaw opening sensor, involution button are existing, and buzzer siren is existing（Only need to adjust its output sound
Frequently, differentiate with former warning function）, without the need for increasing other elements, low cost, implementation result is high.
The beneficial effects of the utility model：
Jaw opening sensor can be applied to manual control circuit by gate hoist electric control system after improvement, be led to
The prompting operator that blow a whistle for crossing buzzer improve attention.The simultaneously delay cut-off at standard-sized sheet position or fully closed position, gate is such as
Fruit needs continue to lift up limit position needs staff's now manual operation, it is to avoid manual control circuit only has mechanical position limitation and opens
Single protection situation of protection is closed, is prevented because of serious consequence caused by mechanical limit switch failure, operator's carelessness.Make full use of
The existing components and parts of gate hoist, low cost, while the processing safety of gate is greatly improved, is widely used in other locks
Door headstock gear, implementation is simple, and equipment, operator and environment will not be impacted, and realizability is high, is easy to promote.
