Description
Technical field
The utility model relates to a kind of pick-up unit, is applicable to that the automatic windrow travel distance of large-scale industrial and mineral equipment stacker detects.
Background technology
Large-scale industrial and mineral equipment mixed-windrowed locomotive is the major equipment that steel industry mixing mineral aggregate field is used for the operation of mixing windrow.Its stock ground length is generally at 400～600 meters, and in order to realize automatic windrow technology, travel distance is necessary test item.What adopt at present is the distance detection method of infrared detection belt feeder carrying roller number, because belt feeder passes under the stacker, idlers pitch equates, is feasible generally speaking.But find in actual use, sometimes the terminal location skew, the afterbody that occur setting move, the numeration according to can not reflecting physical location, can not become the back and forth windrow etc. automatically of starting point in the terminal of setting, thereby the effect of the distance detecting method of infrared ray carrying roller counting can't satisfy the demand of production.In view of above situation, the best way is the physical location that adopts the absolute distance detector to come accurate checkout equipment, but satisfies costing an arm and a leg of the import radar precision ranging instrument that detects 500 meters distances.
In sum, the travel distance pick-up unit of existing large-scale mixed-windrowed locomotive has following defective: 1. infrared counting is subject to disturb to produce error, and data error can cause the stacker terminal that plunges off the tracks when serious; 2. because causing, counting error can not realize automatic windrow in the terminal change starting point of setting; 3. the position of starting point, terminal changes influences mixing mineral amount; 4. can not restart windrow from breakpoint automatically when accident (as outage, outage when not having the material pause, plc fault etc.) takes place in the windrow process and influence the mixing quality; 5. increased production cost greatly as the absolute distance checkout equipment that uses long distance.
Summary of the invention
The purpose of this utility model is to address the above problem and the automatic windrow travel distance of a kind of stacker pick-up unit is provided, this device can not produce interference, so error can not take place in the travel distance numerical value of measuring, reliable and stable, can accurately become starting point in the terminal of setting simultaneously and realize automatic windrow, production cost is lower.
The technical scheme that the utility model adopted is:
The automatic windrow travel distance of a kind of stacker pick-up unit, comprise stacker, PLC, traveling control device, the signal output part of described PLC links to each other with the signal input part of traveling control device, described traveling control device control stacker moving in orbit, the signal input part of described PLC links to each other with the signal output part of operator's console, on the described ground that is parallel to track the coding rule is installed, the scale pick-up is installed on the described stacker, and described scale pick-up moves along with moving of stacker.
Further, described scale pick-up is the metal inductive switch.
Further, described coding rule can be magnetostatic grid chi.
Further, when the coding rule was quiet magnetic railings ruler, described scale pick-up was magnetostatic grid sources.
Further, the signal output part of described PLC links to each other with the signal input part of display device.The utlity model has following advantage:
This device is difficult for producing interference, and the data that obtain can not produce error, and are reliable and stable; Setting terminal becomes starting point accurately, realizes automatic windrow, can not change the position of starting point and terminal simultaneously, has improved the quality in mixing ore deposit; In the process of windrow as cut off the power supply, have faults such as outage when expecting pause, PLC, can restart windrow from breakpoint automatically; This device is made simple, and production cost is low, is applicable to various stackers.
Description of drawings
Fig. 1 is the structural representation of embodiment 1.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Embodiment 1
With reference to Fig. 1, this device mainly comprises stacker 1, PLC 2, traveling control device 3, coding rule 7 and scale pick-up 8, the signal output part of PLC 2 links to each other with the signal input part of traveling control device 3, traveling control device 3 control stackers moving on track 4, between traveling control device 3 and the stacker 1 reductor 5 is installed, reductor 5 can reduce the speed of travel of stacker 1, motor 9 provides driving moment for the stacker walking, the signal input part of PLC 2 links to each other with the signal output part of operator's console 6, the speed of travel and the direction of operator's console 6 control stackers 1, the signal output part of PLC 2 links to each other with the signal input part of display device 10, and display device 10 shows the various controlled variable of PLC 2, the position simulation drawing, velocity setting value and stacker 1 other parameter and simulation drawing.Coding rule 7 is installed on the ground that is parallel to track 4, scale pick-up 8 is installed on the stacker 1, scale pick-up 8 moves along with moving of stacker 1.
Coding rule 7 in the present embodiment, it as carrier, is carved with the number of 9 16 systems with steel plate above, and scale pick-up 8 is the inductor of nine metal inductive switch one side by side, and the data of coding rule 7 will be guaranteed to read reliably in its installation site.The resolution of coding rule 7 scales will make data bit reduce again and be as the criterion to meet the demands, and could reduce device fabrication and working service cost like this.When resolution was too high, the equipment more than 500 meters of adjusting the distance was without any meaning.Because the length of windrow is greater than 500 meters in the present embodiment, so the resolution of scale be 1 meter comparatively suitable, ultimate range detect reach 512 meters enough, the data bit of simple and easy aftertreatment only needs 9, and 500 meters data that are accurate to 20 of 1 centimetre-sized absolute value mark need processing, so it is 1 meter that minimum scale changes distance, only 9 of the data bit of its inductor, such selection not only had been suitable for but also had reduced the manufacturing and the working service cost of checkout equipment.The scale value that nine inductors are read is sent among the PLC 2 and is deposited, though a variety of causes generation loss of data, but be refreshed at any time after the energising, the range data error can not take place.
Embodiment 2
Embodiment is not as different from Example 1, when the length of windrow less, when needing to improve scale resolution, just need this time to adopt magnetostatic displacement transducer, magnetostatic displacement transducer is used in combination by " magnetostatic grid source " and " quiet magnetic railings ruler " two parts.Rule is quiet magnetic railings ruler, and corresponding scale pick-up also will become magnetostatic grid source accordingly.The scale of magnetostatic grid volume rate respectively can reach 1 millimeter or even 0.2 millimeter, can improve degree of accuracy greatly like this.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
