Fig. 1 is the structural representation of the automatic lifting system of the metallurgical cucurbit of ring rail;
Fig. 2 is based on the trolley disjunction control chart of PLC;
Fig. 3 slip PLC controls electrical schematic diagram;
Fig. 4 is metallurgical cucurbit operation control electrical schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is the structural representation of the automatic lifting system of the metallurgical cucurbit of ring rail.The utility model is improved to the circular orbit design with original linear path, makes that metallurgical cucurbit can be in circular orbit cocycle operation, and actv. is increased work efficiency.Wherein circular orbit is successively through four zones, i.e. the car district is treated in melting feeding area 3, cast a district, cast b district, automatic carrier return section and maintenance.The slip that is positioned on the circular orbit is divided into seven sections altogether, is realized the sequence control of break-make electricity by PLC.Whole automatic lifting system has four metallurgical cucurbits (can adjust by technological requirement) to form, and wherein dual-purpose two are equipped with.
Whole lifting system is made up of three key elements, and the one, realize control by PLC to the slip electric power system, accomplish metallurgical cucurbit AutoPlay function through PLC control trolley break-make electricity; The 2nd, realize control by frequency converter to metallurgical cucurbit operation; The 3rd, remote controller is the control of conversion automatically.
Respectively there is a remote control transmitter can control the operation of metallurgical cucurbit in the one's respective area in melting feeding area 3, cast a district, cast b district.Wherein, distant control function comprises that metallurgical cucurbit frequency conversion moves forward and backward; Double speed goes up and down; The upset of transhipment bag both forward and reverse directions; The metallurgical cucurbit of letting pass when the peaking zero clearing that moves automatically and weigh when hoisting.Metallurgical in addition cucurbit is furnished with weighing system, and weight display is housed, and metallurgical cucurbit runs to the assigned address automatic clear, if automatic clear is failed then the manual zero clearing that can use a teleswitch.
Melting feeding area 3 A that uses a teleswitch manually controls metallurgical cucurbit and carries out before the electric furnace of appointment in the transhipment bag, pouring molten iron into, is raised to the extreme higher position after accomplishing charging, starts operation button automatically, and metallurgical cucurbit runs to automatic train stop position 1 automatically and stops.A is transformed into B automatically at this remote position control receptor.Remote-controlled receiver converted A into by B automatically when reversing sense was exercised.Under the situation of treating parking stall 2 no cars automatically, move through the zero clearing position of weighing to treating 2 positions, parking stall automatically automatically simultaneously at the dolly of treating parking stall 21 automatically.Automatically the function of operation is accomplished by PLC control trolley break-make electricity.
The pouring area a B that uses a teleswitch manually accomplishes and topples over molten iron work to cating machine, when metallurgical cucurbit rises to vertex, starts operation button automatically, and dolly runs to automatic train stop position 5 automatically and stops.Be automatically converted to C at this remote position control receptor.Receiver of remote-control sytem converted B into by C automatically when reversing sense was exercised.
The pouring area b C that uses a teleswitch manually accomplishes and topples over molten iron work to cating machine; When metallurgical cucurbit rises to vertex; Start automatic operation button, receiver of remote-control sytem C SELF CL when metallurgical cucurbit passes through automatic operation acceleration point, metallurgical cucurbit auto acceleration runs to and treats parking stall 21 parkings automatically.If treat parking stall 2 no cars, then metallurgical cucurbit continues to exercise treats that parking stall 2 stops.
For preventing dangerous generation, do not allow to exist simultaneously two metallurgical cucurbits with cast a district, cast b in the district at melting feeding area 3.
Fig. 2, Fig. 3, Fig. 4 are the electrical schematic diagram of the metallurgical cucurbit lifting system of PLC control.System is by low-voltage electrical apparatus and crossbar switches such as PLC S7-200, ABB frequency converter, circuit breaker, contactless switchs, form near electric elementss such as switch, photoelectric switchs.
According to technological requirement, slip is divided into seven sections, respectively called after: No. 1 section slip, No. 2 section slips, No. 3 section slips, No. 4 section slips, No. 5 section slips, No. 6 section slips, No. 7 section slips.Detecting devices such as photoelectric switch or travel switch are housed in the turnover of every section slip,, control the break-make of corresponding slip power supply through PLC with this to detect the particular location of metallurgical cucurbit operation.
As shown in Figure 3, by technological requirement, distribute the input end of PLC, the output point of PLC is Q00, Q01, Q02, Q03, Q04, output signal is controlled AC contactor Ka1, Ka2, Ka31, Ka4, Ka5 respectively.By Ka1 open contact control slip total contactless switch KM0 that supplies power, control the break-make of whole ring rail slip power supply with it; Ka2 normally closed contact control contactor KM11 realizes No. 4 section outages; Ka3 normally closed contact control contactor KM10 realizes No. 2 section outages; Ka4 normally closed contact control contactor KM8 realizes No. 5 section outages; Ka5 open contact control contactor KM9 realizes No. 6 section power supplies.
Above content is the further explain that combines concrete optimal technical scheme that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
