Description
Technical field
The utility model relates to a kind of hydraulic headstock gear PLC monitoring cabinet, belongs to the hydraulic control device technical field.
Background technology
People satisfy flood control, generating, industrial or agricultural water etc. in order freely to control the water level in reservoir, river course, and the gate Hydraulic Hoist System must be set, and the key equipment of controlling the operation of this system promptly is a gate hydraulic headstock gear electrical control cabinet.How the performance of switch board directly determines the ruuning situation of gate hydraulic headstock gear.As needing flood discharge at flood control reservoir in season, and gate hydraulic headstock gear electrical control cabinet operation is malfunctioning, and starting gate makes the reservoir dam break timely, will cause the beyond measure loss of the people's lives and property.
Gate hydraulic headstock gear electrical control cabinet in the past can only carry out shirtsleeve operation, no perfect safeguard measure, can not carry out lock position and loading setting and detection, no automaton, does not satisfy the requirement of distant place computer monitoring, video monitor and voice communication.
Summary of the invention:
At the defective of prior art, the utility model provide a kind of reasonable in design, easy to manufacture, simple to operate, volume is little, cost is low, can realize seriation, has the hydraulic headstock gear PLC monitoring cabinet of extensive promotional value.
A kind of hydraulic headstock gear PLC monitoring cabinet is equipped with instrument, pilot lamp, gauge tap and the digital display touch-screen of monitoring gate hydraulic oil pump motor operating state on the monitoring cabinet guidance panel; Monitoring cabinet is connected with two power supplys with double power supply automatic switching switch by D.C mutual-inductor; Monitoring cabinet is connected with hydraulic oil pump with parallel circuit, current transformer and the cable of A.C. contactor by air-break, soft initiator, and is machine room light fixture, Programmable Logic Controller PLC, instrument and the power supply of digital display touch-screen by air switch respectively.
Described hydraulic oil pump is connected with Programmable Logic Controller PLC by sensor.
Described D.C mutual-inductor LZK-0.66-0.5.
Described double power supply converting switch ATQ30D.
Described air-break HIBL103NEM.
Described soft initiator XPRI-3000CN.
Described A.C. contactor HAB22.
Described air switch C65N-C10A.
This switch board is controlled 2 gate hole oil pressure headstock gears, the left and right oil cylinder of every headstock gear is installed the gatage sensor respectively, by secondary cable signal is imported the gatage Displaying Meter, carry out online demonstration, Displaying Meter is imported PLC with signal simultaneously, all can show at touch-screen and distant place computing machine.
During pump start, in order to reduce voltage drop and to the impact of oil pump, electric current is powered to motor by the HL-C1 loop during startup, this moment, starting current had only 1.5 ~ 2Ie, and through finishing startup several seconds, C1 disconnects, open excision by HAB22 with soft, adopt the normal power supply mode.
When rising of two oil cylinders closed stroke when different, what PLC output signal after relatively drove the upper oil cavitie of certain oil cylinder or lower oil cavitie send the fuel tap door, makes the hoisting depth of two oil cylinders synchronous.
The unlatching (closing) that gate can be set arbitrarily highly.On touch-screen, set gate opening (closing) highly by touch button and digital display screen, (closing) touch button is opened in operation then, gate is opened (closing) under the effect of hydraulic headstock gear, when opening (closing), stop automatically to predefined height, the Brake Electromagnet dead electricity makes gate lock in the fixed position simultaneously.
Auto restore facility.When the oil pressure door is fixed on certain position for a long time,, gate is glided because the pressure of oil cylinder reduces, when being reduced to certain altitude (can be provided with arbitrarily), automatically start a table oil pump, and open relevant solenoid valve automatically and rise to hydraulic pressure and close the Oil cylinder fuel feeding, make gate rise to original state.After starting a table oil pump, if still can not recover height, then start another table oil pump automatically within a certain period of time, make gate recover amphi position, and the alert notice operations staff check reason.
Vision signal links to each other with the video workstation of central control room by hard disk video tape recorder and Industrial Ethernet switch, satisfies the needs of distant place video monitor control.
Voice system links to each other with IP phone adapter and Industrial Ethernet switch by IP phone, satisfies the requirement of the voice communication of each oil pressure station and central control room.
Camera power supply can be controlled by a terrain or a distant place.
The utlity model has following characteristics:
1, by two standby each other power supply power supply, a switch closure of standby power supply automatic transfer equipment during normal the operation, connect a telegram in reply source, satisfy the electricity consumption of gate hydraulic oil pump motor, when this telegram in reply source disappearance, then this circuit switching tripping operation, the switch automatic closing in another loop simultaneously, connect standby power supply, ensure to hydraulic oil pump motor normal power supply.
2,2 gatage sensors are loaded on respectively on left and right two oil cylinders of hydraulic headstock gear, and sensor is all imported PLC by secondary cable with signal, again by the RLC output signal to the instantaneous Lift of screen displaying gate.
3, deviation-correcting function.Close stroke when different when rising of two oil cylinders, by the gatage sensor data to be imported PLC, what PLC output signal after relatively drove the upper oil cavitie of certain oil cylinder or lower oil cavitie send the fuel tap door, makes the hoisting depth of two oil cylinders synchronous.
4, the electric current in hydraulic oil pump loop, voltage directly show by the digital display intelligent table, and the digital display intelligent table reaches PLC with signal simultaneously.
5, the unlatching (closing) that gate can be set arbitrarily highly.On touch-screen, set gate opening (closing) highly by touch button and digital display screen, (closing) touch button is opened in operation then, gate is opened (closing) under the effect of hydraulic headstock gear, when opening (closing), stop automatically to predefined height, the Brake Electromagnet dead electricity makes gate lock in the fixed position simultaneously.
6, auto restore facility.When the oil pressure door is fixed on certain position for a long time,, gate is glided because the pressure of oil cylinder reduces, when being reduced to certain altitude (can be provided with arbitrarily), automatically start a table oil pump, and open relevant solenoid valve automatically and rise to hydraulic pressure and close the Oil cylinder fuel feeding, make gate rise to original state.After starting a table oil pump, if still can not recover height, then start another table oil pump automatically within a certain period of time, make gate recover amphi position, and the alert notice operations staff check reason.
7, have perfect short circuit, overload, low-voltage, gate position limitation protection.When protection action auto stop, the gate Hydraulic Hoist System is protected.
8, has the backup manual operating function.When PLC and touch-screen system break down, can finish the keying function of gate by action button and pilot lamp control.
9, satisfy the function of distant place computer monitoring.All switching values and analog quantity are all imported PLC, link to each other with master system by the Industrial Ethernet switch then, and computer system can be monitored the gate hydraulic headstock gear in the distance.
10, vision signal links to each other with the video workstation of central control room by hard disk video tape recorder and Industrial Ethernet switch, satisfies the needs of distant place video monitor control.
11, voice system links to each other with the Industrial Ethernet switch by IP phone, satisfies the requirement of the voice communication of each oil pressure station and central control room.
12, have simple to operate, volume is little, aesthetic in appearance, cost is low, can realize seriation, has promotional value widely.
