Description
Technical field
This utility model relates to a kind of fish torpedo ladle truck control device.
Background technology
Torpedo tank car is also referred to as torpedo hot metal mixer car, is the hot-metal ladle and carriage of the torpedo walked by beeliner traction.Torpedo tank car can load molten iron 320 tons, loads after molten iron, diesel locomotive be pulled between the up tank switching going to steel mill of rail at the blast furnace tapping hole of iron-smelter, then after tank switching operation operation, molten iron is put into steelmaking converter and make steel.
Based on production requirement, the control device of torpedo tank car is particularly important, and needs control reliably, speed governing is steady, and electric connector is accurate.Therefore control and the automatization patched to torpedo tank car are necessary.
At present, it is the wound rotor serial-resistance speed-regulation motor (i.e. rotor winding rotor AC asynchronous motor) using a 11kW that tank body of torpedo tank car rotates electric driving controlgear on the car controlled of tumbling, then drives the tank body of torpedo tank car to rotate after change speed gear box and chain slow down.
And under car ground electric control system be by change rotor serial-resistance speed-regulation resistance box resistance size thus realize tank body of torpedo tank car rotate tipping speed conversion adjust.Speed adjusting resistance has three groups, and every component three is kept off, and makes the partition running between stopping, low speed, middling speed, high speed of cascade control motor by the master controller on terrestrial operation platform.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of fish torpedo ladle truck control device, operates steadily, and facilitates speed governing, improves smooth speed control.
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of fish torpedo ladle truck control device, including terrestrial contr under performance element, car on car, on car, under performance element, car, terrestrial contr is connected by plug, socket, on described car, performance element is four squirrel-cage adjustable frequency motors or a rotor winding motor, under car, terrestrial contr includes converter, permutator, chopper, three-phase alternating current is connected with converter by chopper, the converter of convertible rotation direction is provided with permutator, in order to regulate the running speed of squirrel-cage adjustable frequency motor；Converter is connected by plug, socket with squirrel-cage adjustable frequency motor or rotor winding motor.
Described converter is provided with fault reset switch.
Described rotor winding motor under car in terrestrial contr by rotor windings short circuit.
Compared with prior art, the beneficial effects of the utility model are:
This utility model is energy-conservation, to electrical network without impact, motor running is steady, speed adjustable range is wide, failure rate is low, maintenance facilitate, last a long time, operate and answer hands.Using variable frequency regulating speed control motor, under car, terrestrial contr controls torpedo tank car, solves the uniformity problem of torpedo tank car terrestrial contr, use Frequency Converter Control, making to reduce in startup, speed regulation process the impact of electric current, improve smooth speed control, torpedo tank car operates steadily；Use permutator can facilitate speed governing.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is control block diagram of the present utility model.
In figure: 1-three-phase alternating current 2-converter 3-plug, socket 4-stator winding 5-rotor windings.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in detail, it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of fish torpedo ladle truck control device, including performance element on car, terrestrial contr under car, performance element on car, under car, terrestrial contr passes through cable and plug, socket 3 connects, on described car, performance element is four squirrel-cage adjustable frequency motors or a rotor winding motor, under car, terrestrial contr includes converter 2, permutator, chopper, three-phase alternating current 1 is connected with converter 2 by chopper, the converter 2 of convertible rotation direction is provided with permutator, in order to regulate running speed and the rotation direction of squirrel-cage adjustable frequency motor；Converter 2 is connected by plug, socket with squirrel-cage adjustable frequency motor or rotor winding motor.
Wherein, converter 2 is provided with fault reset switch, in order to overhaul, to debug.Four squirrel-cage adjustable frequency motors are engaged by gear mechanism with torpedo tank car；Rotor winding motor under car in terrestrial contr by rotor windings 5 short circuit, be mainly used in existing equipment transformation, original serial-resistance speed-regulation change frequency control into.
Under car, terrestrial contr is made up of electrical control cabinet, operating board and on-the-spot terminal box.Being connected by the socket on car and the multi-plug cable under car with under car on car, plug, socket 3 use CTZ-20-S/Z type specialty metallurgy plug/seat (the Fragrance Hill metallurgy electric equipment factory of Ningbo Bao Xin group).The volume of this plug is big, and the weight together with connecting cable is the biggest.Patching for on-the-spot operator of plug is a bigger muscle power job.Therefore, after torpedo tank car arrival is in place, realize plug by mechanical arm or robot, the automatic aligning of socket 3 patches.Actual application uses on torpedo tank car the squirrel-cage adjustable frequency motor of four 3kW.Under car, terrestrial contr uses Siemens's MM440 Series Frequency Converter of a 15kW to carry out variable frequency regulating speed control.Motor speed governing operation of wide scope between 0-50Hz is made by the master controller on terrestrial operation platform.
Also existing torpedo tank car can be transformed, wound rotor serial-resistance speed-regulation motor restoration and reuse is become the motor-operation of variable frequency regulating speed control.Will rotor windings 5 output point of torpedo tank car wound rotor serial-resistance speed-regulation motor of old design link ground terminal box by plug, socket 3 cable in carry out short circuit.Under this sample car, terrestrial contr i.e. can control new-type torpedo tank car, it is also possible to controls old-fashioned torpedo tank car.
