Especially, the axle of described roller is provided with the two described coders of cover.
Further, described coder is band DP communication absolute value encoder.
the utility model blast-furnace skip car delivery system, height and speed by coder real-time detecting material car, and the detection signal that detects is fed back to the PLC controller, the PLC controller calculates actual height and the speed of truck according to detection signal, and export control signal according to this height and speed to engine installation and driving device, realize slipping when truck band material stops the automatic detection of car, and automatically truck is directed to perch, simultaneously the height of truck is measured accurately, the car that slips automatically is put into material and cheats, prevent that truck from rushing to summit, cause huge breakdown of equipment and economic loss.
Description of drawings
Fig. 1 is the structural representation of the utility model blast-furnace skip car delivery system.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, the utility model blast-furnace skip car delivery system, comprise PLC controller 10, the engine installation that is connected with described PLC controller and driving device and the oblique rail 6 of truck, wherein, described PLC controller, be used for detecting in real time transportation speed and the direction of described truck, the output control signal is given described engine installation and described driving device;
The clutch end of described engine installation connects described driving device, and being used for provides described driving device work required power, and described engine installation comprises elevator motor 3 and is connected the reductor 4 that elevator motor power mouth connects;
Described driving device comprises the top wheel that is arranged on described oblique rail top and the roller 5 that is arranged on described oblique rail below, the band-type brake 2 that described roller connects, and be arranged on coder 1 on described roller shaft, described top wheel 9 be connected roller and connect by steel rope 8, wherein said coder connects described PLC controller, be used for to described PLC controller output detection signal, the clutch end of described reductor connects the axle of described roller.
Especially, the axle of described roller is provided with the two described coders of cover, and described coder is band DP communication absolute value encoder, and described PLC controller comprises the audible alarm unit (not shown).
The utility model blast-furnace skip car delivery system reads code device signal by PLC, and two absolute value encoders with the DP communication are arranged on the axle of steel rope roller.The signal of coder reads in the DP mode by PLC.Judge kinematic velocity and the direction of truck, when speed is opposite with predetermined speed and when exceeding certain restriction, will sends and slip car and report to the police, device can be controlled the work of elevator motor and band-type brake, and heavily loaded truck is put into safe condition.Can deliver to the PLC controller outward by communication or 4～20mA electric current with slip car signal, length signals and truck speed signal that the absolute value encoder of DP communication sends.
When truck was up, the PLC controller will provide that left car is up or right car is up, receiving truck when up, according to different truck upward signals, set up corresponding Directional Sign.
Situation one: left car is up, the numerical value of coder increases, the up speed gauge of truck at last on the occasion of, bide one's time when left car band material etc. occurring, when upper close inspection is passed through, truck should continue up, if there is loaded vehicle, elevator can not be set up enough high-torques, and the heavy burden truck will down slip car, and the speed that truck detected when the PLC controller according to the detection signal of coder output is less than or equal to-0.3m/s the time, send the band-type brake instruction, simultaneously voice device can send, and slips the alerting signal of car, controls band-type brake work.Truck comes to a complete stop, and time-delay repeats process just now again, truck is put into expects in the hole, in the situation that left car upward signal exists, left car can be according to program, and the left car in material hole can be moved material in the furnace roof hopper, and the flow process of blast furnace can not be affected.
situation two: right car is up, the numerical value of coder reduces, the up speed gauge of truck is negative value, bide one's time when right car band material etc. occurring, when upper close inspection is passed through, truck should continue up, if there is loaded vehicle, elevator can not be set up enough high-torques, the heavy burden truck will down slip car, the speed that truck detected according to the detection signal of coder output when the PLC controller is less than or equal to 0.3m/s the time, send the band-type brake instruction, voice device can send simultaneously, slip the alerting signal of car, truck comes to a complete stop, time-delay repeats process just now again, truck is put into expects in the hole, in the situation that right car upward signal exists, right car can be according to program, the right car in material hole can be moved material in the furnace roof hopper, the flow process of blast furnace can not be affected.
Detecting device adopts two cover coders, in the time of work, if two sets of data difference will be sent warning greatly, is as the criterion with a cover by artificial selection, if when moving, a cover coder breaks down, system automatically switches on the good coder of state.And send warning, when coder all during fault, can not allow truck work.By the two cover coders altitude signals that can take out truck, and speed signal, can issue high furnace control system by DP communication and 4～20mA.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
