Abstract
The utility model discloses a locking device for ensuring a coke pot in place by utilizing limit switches and aims at reducing design-wiring cost and construction and facilitating maintenance. The locking device comprises the limit switches and an arc-shaped induction piece. The limit switches comprise a centering limit switch, a locking-closing limit switch and a locking-opening limit switch, wherein all the three types of limit switches are common limit switches with signals being 0 in normal state and 1 after induction; the centering limit switch is installed above the left of a motor positioning support and welded and erected by a piece of angle steel; the locking-closing limit switch is installed at the top right corner of the motor positioning support; the locking-opening limit switch is installed at the bottom right corner of the motor positioning support; the centering limit switch is connected in series with a normally-open contact of the locking-opening limit switch; and the arc-shaped induction piece is installed at the outer side of the bottom of the coke pot and welded and fixed by a piece of transverse iron.
Description
Technical field
The utility model relates to a kind of coke oven electrical control equipment.
Background technology
The vehicle that coke tank truck is connected with dry coke quenching as coke oven, normally operational relation is to coke oven High-efficient Production, dried steady running of putting out stove and generating, burnt jar Rotation Design is to select for use frequency transformer as driving mechanism, after meeting Jiao at every turn and finishing can through deceleration and the parking limit switch put in place stop after, by regulating motor, begin traveling then with Jiao's jar locking.But from on-the-spot physical device service data; burnt jar many because of burnt jar of end foreign material; the state of Changes in weather deceleration machine oil; the inhomogeneous situations such as deflecting torque that exist of the coke distribution of packing into; it is not in place that rotation appears in Shi Changhui; but the centering slide block is in the extraneous situation of motor locking of regulating; regulate motor and still carry out locking; actual burnt jar is not put in place; but allow travelled by vehicle to dry coke quenching; like this in lifting process; the easy generation of lift is carried Jiao's jar and is caused burnt jar of inclination partially; red Jiao is overflowed; there is the serious person in production unit danger accident events such as suspension hook breaks; device security hidden danger.
Summary of the invention
The utility model purpose is the deficiency that overcomes above-mentioned prior art, provides a kind of a kind of limit switch that utilizes that alleviates designing wiring expense and construction volume, is convenient to safeguard to guarantee the burnt jar locking device that puts in place.
The utility model comprises limit switch and arc sensing chip; Limit switch comprises that centering limit switch, locking close limit switch and locking opening limit switch; It is 0 that three kinds of limit switches all adopt the signal normality, and induction back signal is 1 common limit switch, and the centering limit switch is installed in the upper left side of motor locating support, is erect by the angle steel welding.Locking is closed the upper right corner that limit switch is installed in the motor locating support, and the locking opening limit switch is installed in the lower right corner of motor locating support.The arc sensing chip is installed in the burnt pot bottom outside, and is fixing by horizontal iron welding.Regulating increase centering limit switch on the motor, the normally opened contact of centering limit switch and locking opening limit switch is in series, utilize in the centering limit switch a pair of normally opened contact and burnt jar to forward the tinsel induction of welding on the burnt jar underframe in back, position to and form the loop, just can carry out the locking order after the promptly burnt jar centering.
The utility model is applicable to the control in the swivel arrangement docking process.Utilize limit switch and outside sensing apparatus to judge whether machinery puts in place; Two limit switches are directly connected, and have alleviated designing wiring expense and construction volume, have avoided PLC control, do not increase new control linkage point, are convenient to safeguard, and are more directly perceived, can alleviate designing wiring expense and construction volume.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Arc sensing chip 9 is installed in burnt jar of 1 bottom outside, burnt jar slide block 2 be positioned at burnt jar 1 under, motor location reel 3 is positioned at burnt jar of slide block 2 belows.Centering limit switch 8 is installed in the upper left side of motor locating support 5, and centering limit switch 8 is burnt jar 1 position of rotation of locking accurately; Arc sensing chip 9 is responded to the spacing stop sign that sends after receiving parking order; Locking is closed reels 3 passes, limit switch 4 control motor location and is put in place, and locking opening limit switch 6 control motors location reels 3 are opened and put in place.Guarantee behind reel 3 rotary lockings of motor location that burnt jar 1 no longer swings back and forth.Centering limit switch 8 is connected by series conductor 7 with locking opening limit switch 6.
