Description
Technical field
The present invention relates to the hot industry production line of industries such as Ferrous Metallurgy, particularly a kind of blocked shot pick-up unit.
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, shift variance takes place in transport process, thereby cause the blocked shot accumulation in order to prevent product; The one side waste material, strong wallop also can be damaged production equipment on the other hand.The external at present panalarm that uses can only carry out detection alarm to carefully rolling the position, and sensing range is little.And in the roughing position, the probability that blocked shot takes place is also very big, and destructiveness is bigger, but because the roughing position has the spray cooling, 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, to the protection of the destructive power that produces, early stage warning and brake hard timely all are 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 blocked shot pick-up unit.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 blocked shot pick-up unit; It is characterized in that: comprise the moment impact damper that detects metal detection frame, first stainless steel gear and second stainless steel gear be transmitted object and constitute, by travel switch, twine copper wire, the high temperature resistant airtight ceramic package of band fixing threaded hole and elevated-temperature seal sensing mechanism and the PLC controller that the waterproof aviation plug constitutes; Said metal detection frame is connected with first stainless steel gear, one end of moment impact damper through the first bronze medal bar; 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 the high temperature resistant airtight ceramic package; With two travel switch clearance fit that are sealed in the high temperature resistant airtight ceramic package, two twine copper wire, and 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 through fixing threaded hole with fixed screw, and the waterproof aviation plug is installed on the high temperature resistant airtight ceramic package, and is connected with the connection terminal of PLC controller through sheathed cable.
The beneficial effect that the present invention produced is: this device has characteristics such as overall tightness is strong, high temperature resistant, shock-resistant, can adapt to on-the-spot bad 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 vast market prospect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further: with reference to Fig. 1; The blocked shot pick-up unit comprises the moment impact damper 2 that detects the metal detection frame 1 be transmitted object 1-1, be made up of stainless steel gear 2-1 and stainless steel gear 2-2, by travel switch 3-1, twine elevated-temperature seal sensing mechanism 3 and PLC controller 4 that copper wire 3-2, fixed screw 3-3, the band high temperature resistant airtight ceramic package 3-4 of fixing threaded hole and waterproof aviation plug 3-5 constitute; Metal detection frame 1 is connected with stainless steel gear 2-1 one end of moment impact damper 2 through 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 the high temperature resistant airtight ceramic package 3-4; With two travel switch 3-1 clearance fit that are sealed in the high temperature resistant airtight ceramic package 3-4; Two twine copper wire 3-2; Wherein one is wrapped on the second bronze medal bar 1-3, and another root is connected with two travel switch 3-1 respectively, and high temperature resistant airtight ceramic package 3-4 is fixed on the detection position through fixing threaded hole with fixed screw 3-3; Waterproof aviation plug 3-5 is installed on the high temperature resistant airtight ceramic package 3-4, and is connected with the connection terminal 4-1 of PLC controller 4 through 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 for use; Through bending; Process the metal detection frame of different girths, then head and the tail welded), the geometric center that the metal detection frame is processed the metal detection frame by Φ 20mm copper bar is concentric with the roughing export center.Object 1-1 to be detected can move to any direction when blocked shot takes place.The first bronze medal bar 1-2 and the second bronze medal bar 1-3 process 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 great high-temperature resistant.High temperature resistant airtight ceramic package is provided with the installation screw, makes things convenient for location and installation.Adopt position probing and energising to detect dual mode simultaneously and detect the blocked shot phenomenon, reliability is high.
This device adopts intelligent control method; The signal of sensor transfers back to the PLC controller through sheathed cable, through the PLC controller to Signal Processing and analysis; Can carry out corresponding warning light demonstration and take brake hard action etc., thereby realize the function of warning and monitoring and protection.
Principle of work of the present invention: object 1-1 to be detected 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, under normal situation about transmitting, object 1-1 to be detected should not contact with metal detection frame 1 in the transport process.When the blocked shot situation took place, irregular at random displacement took place in object 1-1 to be detected, 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 terminal touching of second bronze medal bar 1-3 travel switch 3-1 simultaneously; Then the travel switch signal is sent to PLC controller 4 through sheathed cable 3-6 and carries out signal Processing, can carry out corresponding warning light and show 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 twine copper wire 3-2 and ground conducting, the Continuity signal that then twines copper wire 3-2 is sent to PLC controller 4 through sheathed cable 3-6 and carries out signal Processing, also can carry out corresponding warning light demonstration and take brake hard action etc.
