Description
Technical field
What the present invention relates to is a kind of putty detection control apparatus for band conveyor.
Background technology
At present in metallurgy industry, band conveyor is as the instrument of material transportation, in the material handling link, play an important role, generally speaking, many belt transporters of material traffic requirements cooperate to be finished, and at the end of a belt transporter, discharge tube is arranged usually, by barrel material is discharged at the front end of another belt transporter, realizes the transportation continuously of material.
In the operational process of band conveyor, cause the belt feeder end putty phenomenon to occur owing to often have bulk foreign matters such as steel plate, lump ore in the material, cause the band conveyor overload, cause the band conveyor actuating device to damage, perhaps cause foreign matter to damage band conveyor, cause whole band conveyor to be torn, cause serious economy loss.
Now big multiple enterprises uses stuff level switch to detect whether putty of control belt, and this stuff level switch action is unstable, damages easily.This is the existing in prior technology weak point.
Summary of the invention
Purpose of the present invention is exactly at the existing in prior technology deficiency, and provide a kind of technical scheme of band conveyor putty detection control apparatus, the device of this scheme is installed on the end of band conveyor, the front end of discharge tube, this apparatus structure is simple, easy to maintenance, accurately and reliably, can fast detecting arrive putty, course of action is exceedingly fast, and can find band conveyor putty phenomenon effectively, timely, avoids the generation of accident.
This programme is realized by following technical measures: a kind of band conveyor putty detection control apparatus, comprise support, the PLC controller, the characteristics of this programme are: the bottom of described support is provided with detecting device, described detecting device comprises strut bar, putty piece and switch reflecting plate, bracing frame is fixed on the bottom of support and can rotates around support, the putty piece is fixed on an end of strut bar, the switch reflecting plate is fixed on the other end of strut bar, have one to be fixed on the described support with the proximity transducer of switch reflecting plate coupling, described proximity transducer is connected with the PLC controller.
Preferred putty piece is the putty ball.The quality of described putty ball is M1, and the quality of switch reflecting plate is M2, M1＞M2.
Described frame bottom is provided with for limiting the whereabouts position-limited rack that strut bar rotates.Described whereabouts position-limited rack is L shaped.
Preferred support is ├ shape.Described proximity transducer is fixed on the cross bar of ├ shape support.The cross bar of described ├ shape support is provided with the proximity transducer track.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme, there is the PLC controller to control corresponding band conveyor, bottom at support is provided with strut bar, the two ends of strut bar have putty piece and switch reflecting plate respectively, when the putty phenomenon occurring, the putty piece can move, and then the action of switch reflecting plate, after proximity transducer detects the action of switch reflecting plate, transfer signals to the PLC controller; The weight of putty ball is greater than the weight of switch reflecting plate, so an end of putty ball can sink, frame bottom has the whereabouts position-limited rack, can limit the height of putty ball; The cross bar of ├ shape support is provided with the proximity transducer track, is convenient to adjust the position of proximity transducer, more accurate detection.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Fig. 2 is the structural representation of cross bar.
Among the figure, 1 is the putty ball, and 2 is strut bar, and 3 is the whereabouts position-limited rack, and 4 is the switch reflecting plate, and 5 is support, and 6 is proximity transducer, and 7 is band conveyor, and 8 is the PLC controller, and 9 is material, and 10 is cross bar, and 11 is the proximity transducer track.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
The specific embodiment one
By accompanying drawing as can be seen, the band conveyor putty detection control apparatus of this programme, comprise support 5, PLC controller 8, the bottom of described support 5 is provided with detecting device, described detecting device comprises strut bar 2, putty piece and switch reflecting plate 4, bracing frame 2 is fixed on the bottom of support 5 and can rotates around support 5, the putty piece is fixed on an end of strut bar 2, switch reflecting plate 4 is fixed on the other end of strut bar, have one to be fixed on the described support 5 with the proximity transducer 6 of switch reflecting plate 4 coupling, described proximity transducer 6 is connected with PLC controller 8, and the putty piece is putty ball 1.
The quality of described putty ball 1 is M1, and the quality of switch reflecting plate 4 is M2, M1＞M2, and described support 5 bottoms are provided with for limiting the whereabouts position-limited rack 3 that strut bar 2 rotates.Described whereabouts position-limited rack 3 is L shaped.
The specific embodiment two
The band conveyor putty detection control apparatus of this programme, comprise support 5, PLC controller 8, the bottom of described support 5 is provided with detecting device, described detecting device comprises strut bar 2, putty piece and switch reflecting plate 4, bracing frame 2 is fixed on the bottom of support 5 and can rotates around support 5, the putty piece is fixed on an end of strut bar 2, switch reflecting plate 4 is fixed on the other end of strut bar, have one to be fixed on the described support 5 with the proximity transducer 6 of switch reflecting plate 4 coupling, described proximity transducer 6 is connected with PLC controller 8, and the putty piece is putty ball 1.
Support 5 is ├ shape.Described proximity transducer 6 is fixed on the cross bar of ├ shape support 5.The cross bar 10 of described ├ shape support 5 is provided with proximity transducer track 11.
During work, the device of this programme is installed on the end of band conveyor 7, the front end of discharge tube, because putty ball 1 weight is greater than the weight of switch reflecting plate 4, strut bar 2 is moving up and down around support 5, the level attitude of putty ball 1 is lower than switch reflecting plate 4, whereabouts limiting bracket 3 is propped strut bar 2, band conveyor 7 operations constantly under the normal circumstances, band conveyor 7 runnings are advanced from right to left, driving material 9 advances from right to left, material 9 on the band conveyor 7 highly can not run into putty ball 1, when having the bulk foreign matter in the material 9, because the bulk foreign matter is blocked the band conveyor discharge tube, can cause the position lifting of band conveyor end materials 9, along with getting more and more of material 9, material 9 is lifted to certain altitude will run into putty ball 1, with the 1 upwards lifting of putty ball, by lever principle as can be known, putty ball 1 upwards lifting will cause that switch reflecting plate 4 falls downwards, along with the 1 upwards lifting of putty ball, switch reflecting plate 4 will be close to proximity transducer 6, proximity transducer 6 sends the putty signal and gives PLC controller 8, send cutoff command by PLC controller 8 and give actuating unit, actuating unit stops band conveyor 7, stop when realizing band conveyor 7 putties, avoid band conveyor to tear, reduce economic loss.
The present invention is not limited in the above-mentioned specific embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
