This utility model by controlling elevator height and translation distance using various detection switch, and by detection signal
The PLC sending into elevator participates in chain control, and PLC controls the switching of low middle high three kinds of speed of elevator it is ensured that elevator
Variable-speed operation by the operation curve figure safety and stability of regulation.
Elevator is provided with 3 kinds of speed, to adapt to the requirement of elevated height and low speed para-position.According to different lift strokes,
Speed changes instruction, is detected by contactless proximity switch, within hoisting depth error is maintained at ± 45mm.Running mechanism
It is provided with 2 kinds of speed, to adapt to the requirement of quick traveling and exactitude position.The position of traversing traveling to be examined by contactless proximity switch
Survey.For ensureing traversing accurate contraposition, elevator adopts automatic retarding, the alignment mode of detection, and its bit errors is in ± 20mm
Within.
Profibus-DP (or DeviceNET) bus is passed through in elevator lifting, traveling converter plant and control system connects
Connect, unmanned, it is desirable to action is all automatically performed, and requires to keep certain rhythm of production at ordinary times for the operation of elevator.
Controlling using lifting, the method for traveling multistage speed of elevator body, both can improve certain efficiency, can reduce punching again
Hit and ensure the precision positioning.
During the traversing traveling of elevator, under conditions of automatic running, elevator initially enters high speed traveling, arrives
It is reduced to low speed after reaching deceleration position, reach position location and stop.
During lifting and declining operation, using the method for multiple velocity variations, main purpose is to reduce to elevator
Equipment impact and raising run rhythm.Speed controlling in lifting process provides position letter by elevator raised position detection switch
Number with determine lifting speed, cooperation elevator winding shaft side, coke quencher's side Rule of judgment, and lifting and rise and fall Rule of judgment
Select different speed systems of selection.During being illustrated in figure 2 elevator automatic running, the Speed allotment side of lifting and traveling
Formula.During lifting and decline, the change that elevator lifts speed is automatically real according to the detection of raised position detection switch
Existing.The difficult point controlling lies also in loading furnace process (going journey) and return course (return), and the speed of elevator lifting and traveling is divided
Join problem.
Control device described in the utility model is experimentally come into operation, has hauled oneself willingly into since using, normal operation.At ordinary times
In maintenance process, due to the stretching of steel wire rope of hoist and the change of mechanical clearance, the inspection of elevator raised position detection switch
Survey data compared with slight change in debugging process, should be noted in maintenance process at ordinary times.Avoid because of detection switch detection signal
Change causes the situation of impact system operation.
The safe operation of coke dry quenching hoister is an important step of dry quenching system stable operation, and dry coke quenching lifting
In machine control, the judgement of burnt tank position is then the most important thing, using limit switch, this utility model judges that burnt tank puts in place traditional
On control mode basis, install various detection switch especially speed change point detection switch additional to judge, thus realize dry coke quenching carrying
The reliable shutdown of the machine of liter.
The above is preferred implementation of the present utility model, comes for those skilled in the art
Say, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improvements and modifications also by
It is considered as protection domain of the present utility model.
