Description
The invention belongs to a kind of protection device, specifically a kind of stacker-reclaimer reel towing cable protection device.
Background technology
During the stacker-reclaimer operation of stock ground, by reel reel to the batching of towing cable, discharge and reach the synchronization of stacker-reclaimer
Power supply and signal transmission.During the stacker-reclaimer walking of stock ground, accident often occurs for its reel towing cable, and accident shows as stacker-reclaimer and existed
Walking, and reel reel is stopped operating so that towing cable is deposited on stacker-reclaimer guide rail, by the bolt of fixed guide rail hang up or by
Stacker-reclaimer is rolled bad.Method described in the patent of Application No. 201020032924.7 it is possible to prevente effectively from towing cable accident, but this
The method of kind be present：1st, only with a proximity switch, protection device can be caused to lose once this proximity switch breaks down
Effect；2nd, auxiliary reclay frequent movement, once its contact life-span reaches capacity, then protection device fails；3rd, resolution element is more, therefore
Barrier point is more, and reliability is low；4th, coil diameters are typically than larger, and reel uses tower structure, is difficult the letter more than installation number
Number block.When preceding 2 problems occur, protection device failure, towing cable accident will occur.
The content of the invention
The technical problems to be solved by the invention are：How a kind of dress of more preferable protection stacker-reclaimer reel towing cable is provided
Put, the equipment safety is reliable.
The technical solution adopted by the present invention is：A kind of stacker-reclaimer reel towing cable protection device, in the stacker reel and
One disk is installed, the connecting shaft is also the rotating shaft of the disk, on the disk concentric circle in the connecting shaft of reel
Multiple signal masks are uniformly installed, have hole between the disk and the reel, it is close on the stacker job platform
The side surface of disk one is installed and the first proximity switch is installed in first support and second support, the first support, and described the
Installed on two supports any one signal mask position on the second proximity switch, the disk turn to it is close near first
During switch, the first proximity switch triggering, other positions, the first proximity switch is not triggered, any one signal on the disk
When flapper is near the second proximity switch, the triggering of the second proximity switch, the triggering of the second proximity switch, other positions, the
Two proximity switches are not triggered, and first proximity switch and the first proximity switch electric signal connect a Programmable logical controller
Device, the programmable logic controller (PLC) connects the stacker-reclaimer controlling switch.
It is used as a kind of preferred embodiment：Programmable logic controller (PLC) receives the discontinuity switching signal from the first proximity switch
With the discontinuity switching signal from the second proximity switch, the first proximity switch received when programmable logic controller (PLC) or
Second proximity switch any one when sending regular discontinuity switching signal, keep stacker-reclaimer controlling switch to be in and open
State, is otherwise shut off stacker-reclaimer controlling switch.
It is used as a kind of preferred embodiment：The quantity of signal mask is 40, a diameter of 0.5 meter of disk.
The beneficial effects of the invention are as follows：Apparatus of the present invention are respectively carried out to the pulse signal for coming from two proximity switches
Processing, does not rotate as long as there is a proximity switch to detect reel, will send stop signal, so as to stop the row of stacker-reclaimer
Walk, it is to avoid towing cable is deposited on stacker-reclaimer guide rail, the phenomenon hung up or rolled bad by stacker-reclaimer by the bolt of fixed guide rail,
Even if a proximity switch is damaged in apparatus of the present invention, another remaining proximity switch can also realize the protection of towing cable.
Brief description of the drawings
Fig. 1 is disk schematic view of the mounting position of the present invention；
Fig. 2 is signal mask schematic view of the mounting position of the present invention；
Fig. 3 is the first proximity switch schematic view of the mounting position of the invention；
Fig. 4 is the second proximity switch schematic view of the mounting position of the invention；
Fig. 5 is PLC controls schematic diagram；
Wherein：1 reel in figure, 2 connecting shafts, 3 disks, 4 reels, 5 signal blocks, 6 first supports, 7 second supports, 8
One proximity switch, 9 second proximity switches.
Embodiment
One rosette of setting, a diameter of 0.5 meter of rosette, on rosette at the radius of the center of circle 2/3
It is uniformly distributed 40 signal blocks of setting.Rosette is installed between reel and reel and is fixedly mounted with reel coaxial, gold
Belong to disk with reel at a distance of 5 centimetres.
As depicted in figs. 1 and 2, one rosette of setting, a diameter of 0.5 meter of metal roundel, on rosette
40 signal blocks of setting are uniformly distributed at the radius of the center of circle 2/3.Rosette be installed between reel and reel and with volume
Disk is coaxially fixedly mounted so that disk and cable drum synchronous axial system, and rosette is with reel at a distance of 5 centimetres.
As shown in Figure 3 and Figure 4, close to metal roundel side right angle setting on stacker-reclaimer job platform and in reel
Two supports, i.e. first support and second support, set the first proximity switch in first support, and is set on the secondary support bracket
Two proximity switches, the mounting distance between the second proximity switch and the first proximity switch will ensure the two proximity switches with height
Two signal blocks of the difference just to rosette horizontal diameter.
As shown in figure 5, setting a programmable logic controller (PLC), programmable logic controller (PLC), which receives to approach from first, to be opened
The pulse signal of pass（Regular discontinuity switching signal）With the pulse signal from the second proximity switch.The arteries and veins of proximity switch
The rotation situation of signal reaction reel is rushed, proximity switch sends continuous pulse signal during reel normal rotation；Reel stops turning
When dynamic, proximity switch does not send pulse signal.The pulse signal that programmable logic controller (PLC) is sent to two proximity switches respectively
Handled, one interlocking of signals stacker-reclaimer walking motor control loop of final output（Controlling switch）.As long as having one
Individual proximity switch detects reel and not rotated, and will send interlock shutdown signal, so as to stop the walking of stacker-reclaimer, it is to avoid drag
Cable is deposited on stacker-reclaimer guide rail, the phenomenon hung up or rolled bad by stacker-reclaimer by the bolt of fixed guide rail.Even if one connects
Nearly switching damage, another remaining proximity switch can also realize the protection of towing cable.Centre is not present in programmable controller simultaneously
The situation in relay tip life-span, and the configuration of discrete electrical equipment is avoided, drastically increase the reliable of protection device
Property.
