Description
Technical field
The present invention relates to the hot industry production line of the industries such as Ferrous Metallurgy, particularly a kind of blocking rod detecting device.
Background technology
In iron and steel metallurgical industry high temperature production line, usually all to be provided with the detection alarm device carefully rolling the position, in order to prevent product, shift variance occur in transport process, thereby cause the blocked shot accumulation, waste material on the one hand, powerful impulsive force also can be damaged production equipment on the other hand.The external panalarm that uses can only carry out detection alarm to carefully rolling the position at present, and sensing range is little.And in the roughing position, the probability that blocked shot occurs is also very large, and destructiveness is larger, but because the roughing position has spraying cooling, the requirements such as pickling cause this position that existing warning device can't be installed.In addition, because the product of roughing position is all much bigger on quality and volume, therefore, for the protection of the destructive power that produces, early stage warning and brake hard timely are all the problems that will solve.
Summary of the invention
In view of above-mentioned prior art situation, the present invention researches and develops a kind of blocking rod detecting device.This device is to integrate sensor, become and to send monitoring and high-performance protective, can be at various high temperature, and many dust, many moistures, long-term stable operation under the rugged surroundings such as many corrosion has rapid reaction and automatic protection functions simultaneously.
the technical scheme that the present invention takes is: a kind of blocking rod detecting device, it is characterized in that: comprise and detect the metal detection frame that is transmitted object, the moment impact damper that the first stainless steel gear and the second stainless steel gear consist of, by travel switch, be wound around copper wire, with the high temperature resistant airtight ceramic package of fixing threaded hole and elevated-temperature seal sensing mechanism and the PLC controller of waterproof aviation plug formation, described metal detection frame is connected with the first stainless steel gear one end of moment impact damper by the first bronze medal bar, the second stainless steel gear is connected with an end of the second bronze medal bar, the other end of the second bronze medal bar puts in high temperature resistant airtight ceramic package, with two travel switch clearance fit that are sealed in high temperature resistant airtight ceramic package, two are wound around copper wire, wherein one is wrapped on the second bronze medal bar, another root is connected with two travel switches respectively, high temperature resistant airtight ceramic package is fixed on the detection position by fixing threaded hole with fixed screw, the waterproof aviation plug is arranged on high temperature resistant airtight ceramic package, and be connected by the connection terminal of sheathed cable with the PLC controller.
The beneficial effect that the present invention produces is: this device has the characteristics such as overall tightness is strong, high temperature resistant, shock-resistant, can adapt to on-the-spot abominable working environment, long service life.The compact conformation volume is little simultaneously, and institute takes up space little, easy installation and removal.Thereby solved at present the problem that blocked shot can't be detected in iron and steel metallurgical industry high temperature production line roughing position.Therefore, have wide market outlook.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
the invention will be further described below in conjunction with accompanying drawing: with reference to Fig. 1, blocking rod detecting device comprises that detection is transmitted the metal detection frame 1 of object 1-1, the moment impact damper 2 that is consisted of by stainless steel gear 2-1 and stainless steel gear 2-2, by travel switch 3-1, be wound around copper wire 3-2, fixed screw 3-3, elevated-temperature seal sensing mechanism 3 and PLC controller 4 with the high temperature resistant airtight ceramic package 3-4 of fixing threaded hole and waterproof aviation plug 3-5 formation, metal detection frame 1 is connected with stainless steel gear 2-1 one end of moment impact damper 2 by the first bronze medal bar 1-2, another stainless steel gear 2-2 is connected with the end of the second bronze medal bar 1-3, the other end of the second bronze medal bar 1-3 puts in high temperature resistant airtight ceramic package 3-4, with two travel switch 3-1 clearance fit that are sealed in high temperature resistant airtight ceramic package 3-4, two are wound around copper wire 3-2, wherein one is wrapped on the second bronze medal bar 1-3, another root is connected with two travel switch 3-1 respectively, high temperature resistant airtight ceramic package 3-4 is fixed on the detection position by fixing threaded hole with fixed screw 3-3, waterproof aviation plug 3-5 is arranged on high temperature resistant airtight ceramic package 3-4, and be connected with the connection terminal 4-1 of PLC controller 4 by sheathed cable 3-6.
Metal detection frame 1 is designed to adjustable type (main diameter according to testee, can select the copper bar of different length, through bending, make the metal detection frame of different girths, then head and the tail are welded), the geometric center that the metal detection frame is made the metal detection frame by Φ 20mm copper bar is concentric with the roughing export center.Detected object 1-1 can move to any direction when blocked shot occurs.The first bronze medal bar 1-2 and the second bronze medal bar 1-3 make by Φ 20mm copper bar.Stainless steel gear is connected with the M16 screw with the copper bar.
The shell of refractory seals sensing mechanism 3 is that stupalith and waterproof aviation plug all possess good sealing effectiveness, can prevent that water smoke, acid mist from causing physical wear to sensor, and possess good resistance to elevated temperatures.High temperature resistant airtight ceramic package is provided with installation screw, facilitates location and installation.Adopt simultaneously position probing and energising to detect dual mode and detect the blocked shot phenomenon, reliability is high.
This device adopts intelligent control method; the signal that sensor detects transfers back to the PLC controller by sheathed cable, by processing and the analysis of PLC controller to signal; can carry out corresponding alarm lamp light display and show and take brake hard action etc., thereby realize the function of warning and monitoring and protection.
Principle of work of the present invention: detected object 1-1 is along the vertical line direction on metal detection frame 1 plane, pass metal detection frame 1, transmit continuously to the front from the back side of metal detection frame 1, in the situation that normal the transmission, in transport process, detected object 1-1 should not contact with metal detection frame 1.When the blocked shot situation occurs, random abnormal displacement occurs in detected object 1-1, can arch upward to any direction, thereby contact with metal detection frame 1, this moment, metal detection frame 1 stressed being subjected to displacement, drove the first bronze medal bar 1-2 and the second bronze medal bar 1-3 moves, the second bronze medal bar 1-3 end touching travel switch 3-1 simultaneously, the travel switch signal is sent to PLC controller 4 by sheathed cable 3-6 and carries out signal and process, and can carry out corresponding alarm lamp light display and shows and take brake hard action etc.; In addition, because measured object 1-1 contacts with metal detection frame 1, and testee 1-1 connects the earth, cause and be wound around copper wire 3-2 and ground conducting, the Continuity signal that is wound around copper wire 3-2 is sent to PLC controller 4 by sheathed cable 3-6 to carry out signal and processes, and also can carry out corresponding alarm lamp light display and shows and take brake hard action etc.
