Abstract
The utility model discloses a dummy bar position detecting device, which comprises a dummy bar and photo-electric switches. Two in-situ detection through holes are arranged in the middle of the dummy bar; an ingot stripping detection through hole is arranged on a rod body close to a free end of the dummy bar; every two of the four photo-electric switches form one group and are respectively oppositely arranged on two sides of the upper side and the lower side of the in-situ detection through hole at intervals; and two opposite photo-electric switches are positioned on the same vertical straight line. The dummy bar position detecting device has simple structure, can increase position accuracy rate by more than 99%, substantially increases accuracy of dummy rod position detection, simultaneously reduces maintenance of maintenance workers to a nearly maintenance free state, and generates larger indirect benefit.
Description
Technical field
The utility model relates to a kind of in order to detect conticaster dummy bar position, to prevent that it from taking off the dummy bar position detecting device of ingot.
Background technology
Existing conticaster dummy bar position probing adopts the pattern in a sender hole of two optoelectronic switches, wherein the sender hole above the dummy ingot pinch roll as former bit flag, an optoelectronic switch is respectively installed in the both sides in hole, another optoelectronic switch is according to taking off the afterbody that the ingot position is contained in dummy bar, be used to take off the detection of ingot position, find that in actual application this pattern has following shortcoming: 1. take off the ingot signal and have interference, or after dummy bar is sent into optoelectronic switch slightly a misalignment just cause the mistake sender, cause the straightening machine to depress dummy bar is broken, this is to want absolute prohibition.2. it is higher to take off optoelectronic switch installation site, ingot position, repairs or adjust relatively difficulty when maintenance or fault.
The utility model content
The purpose of this utility model is to provide a kind of dummy bar position detecting device, and is not only simple in structure, and can detect the dummy bar position rapidly and accurately, can prevent that dummy bar from taking off ingot, can reduce the misoperation rate again, is easy to maintenance and maintenance.
The purpose of this utility model is achieved in that a kind of dummy bar position detecting device, comprise dummy bar and optoelectronic switch, two in situ detection through holes are being set at the middle part of dummy bar, taking off ingot detection through hole near being provided with one on the free-ended body of rod of dummy bar, said optoelectronic switch is four, per two optoelectronic switches be divided into one group respectively relative spacing be arranged on the both sides, above and below of in situ detection through hole, two relative optoelectronic switches are positioned on the same vertical straight line.
The utility model is simple in structure, open three on the dummy bar and detect the hole, wherein two holes are used for detecting original position, a hole is used for detecting takes off the ingot position, when dummy bar in position the time, be positioned at the optoelectronic switch sender of original position, the output high level is the dummy bar original position this moment, when the dummy ingot afterbody leaves optoelectronic switch when dummy ingot is sent into, this moment, this optoelectronic switch was exported high level, and this is for going into the straightening position, and the straightening machine should be depressed, when dummy bar reclaims when taking off ingot detection through-hole alignment optoelectronic switch at this moment for taking off the ingot signal, the straightening machine is depressed and is taken off ingot, and dummy bar stops automatically when treating dummy bar arrival original position, waits for and send dummy ingot next time.This device has increased the quantity that detects through hole and optoelectronic switch, not only improved the position probing accuracy rate of dummy bar, the position probing accuracy rate can be brought up to more than 99%, and reduced the misoperation rate of position probing, increase substantially the accuracy of dummy bar position probing, reduced the maintenance of safeguarding the worker significantly simultaneously, be easy to maintenance and maintenance, near non-maintaining state, the indirect benefit that is produced is bigger.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
A kind of dummy bar position detecting device as shown in drawings, comprises dummy bar 4 and optoelectronic switch 5,6, and dummy bar 4 drives operation by pinch roll 7 rotations.Two in situ detection through holes 1,2 are being set at the middle part of dummy bar 4, are taking off ingot detection through hole 3 near being provided with one on the dummy bar 4 free-ended bodies of rod, each aperture of detecting through hole 1,2,3 is respectively 40mm.Said optoelectronic switch is four, per two optoelectronic switches 5 and per two optoelectronic switches 6 be divided into one group respectively relative spacing be arranged on the both sides, above and below of in situ detection through hole 1,2, relative two optoelectronic switches 5 or 6 are positioned on the same vertical straight line.Photoelectric switching signal is sent in the PLC, is handled by software programming again.Photoelectric switching signal adopts cable transmission, requires to adopt shielded cable, and the on-site cable model is KVVRP-4 * 0.75, requires shielding to connect as requested, guarantees that pulse signal does not disturb; Software programming gets final product according to the programming of dummy ingot position oscillogram, just takes off the ingot position and will adopt negative edge to trigger effectively, takes off ingot position some deviation of possibility in practice, will add when taking off ingot in program that the cut lengths protection is just more reliable.
The utility model is simple in structure, and the position probing accuracy rate can be brought up to more than 99%, has increased substantially the accuracy of dummy bar position probing, has reduced the maintenance of safeguarding the worker significantly simultaneously, and near non-maintaining state, the indirect benefit that is produced is bigger.
