Description

Mechanize pit kiln pushing machine, coke guide, quenching car are to level detecting apparatus

Technical field

The utility model relates to the pit kiln field of security guarantee, specifically is that mechanize pit kiln pushing machine, coke guide, quenching car are to level detecting apparatus.

Background technology

The coke guide of mechanize pit kiln, pushing machine, quenching car three cars are accurately located, are worked asynchronously, and are the basic technology requirements in the coke production, it be guarantee coke oven safely, avoid the key point of great physical abuse.Coke-oven plant's traditional processing technology to the way that addresses this problem is: finish three car Operations Sequence Charts before workshop yardman (production technique authorized personnel) class and be distributed to three car drivers, three car drivers operate according to Operations Sequence Chart.Three car stationary problems are supervised driver's contraposition by furnace roof whistle worker and are operated according to whistle, i.e. labor statement whistle mode.The birth that labor statement whistle mode is accompanied by the mechanize pit kiln continues into the present, and goes through more than 100 year, the own certainty that it exists, but wherein also be accompanied by many helpless.Because three drivers, four people of a whistle worker must keep a cool head simultaneously, proper operation simultaneously under normal circumstances can guarantee the safety of system; But under abnormal situation, one of them people's mishandle all can cause the asynchronous of potential safety hazard, particularly pushing machine in the production process and coke guide, also may cause the great physical abuse of coke oven, and stop work and production; The coke oven owner is when suffering heavy economic losses, and the security context of coke production is destroyed, and coke oven direct labor's personnel safety and psychological security can not get ensureing.

Except that the mode of the labor statement whistle, existing in the market following three kind of three car is to level detecting apparatus: 1, r ray detecting apparatus, after this device utilizes machine, burnt both sides oven door opening, coke guide emission r ray, the r ray passes burner hearth, pushing machine receives the r ray, and two car contrapositions success is blocked, pushed away in expression, guarantees coke pushing, blocks burnt safety.Quenching car is at fixed position emission r ray, and coke guide receives the r ray in the fixed position, have only coke guide to receive the r ray of quenching car after, just two car contrapositions are put out, blocked to expression successfully, lands to prevent red Jiao, guarantees to block Jiao, quenching safety operation.The greatest problem of this device is that the r ray belongs to substantial radiation source, can cause extensive damage to operator's health of human body, thus this device voguish after, progressively eliminated often; 2, coding type proofing unit, this device utilizes near infrared coding cable parallel lay-up pushing machine track, coke guide track, quenching car track, allow infrared encoder aim at each coking chamber, emission coking chamber heat (batch) number is equipped with infrared dash receiver on three cars, after the infrared dash receiver on three cars receives the operation heat (batch) number, whether put in place by the mutual inspection of radio communication three cars, determine then whether pushing ram removes self-locking, guarantee that contraposition is correct, operational safety; 3, distance measuring type proofing unit, this device is measured the distance of three cars with respect to the coke oven point of fixity by range finding means such as tellurometer survey or laser rangings, determine three car positions by calculating, whether put in place by the mutual inspection of radio communication three cars then, whether the decision pushing ram removes self-locking, guarantee that contraposition is correct, operational safety; These two kinds of proofing unit complex structures, cost are expensive (every cover system is all about 1,000,000 yuan of Renminbi) too, can't big area promote on market.

Summary of the invention

The utility model provides a kind of mechanize pit kiln pushing machine, coke guide, quenching car to level detecting apparatus in order to solve existing three cars to problems such as level detecting apparatus complex structure, cost height.

The utility model is to adopt following technical scheme to realize: mechanize pit kiln pushing machine, coke guide, quenching car is to level detecting apparatus, comprise and be arranged at pushing machine, the solenoid Ti corresponding on the quenching car orbit with each carbonization chamber position, Xi, and be arranged at two corresponding on coke guide orbit solenoid LTi with each carbonization chamber position, LXi, solenoid Ti, Xi, LTi, the number of Lxi equates with the coking chamber number, two solenoid LTi on the coke guide orbit, LXi respectively with pushing machine, solenoid Ti on the quenching car orbit, the Xi series connection constitutes the loop, wherein, i is coking chamber chamber number; Also comprise and being arranged at respectively on quenching car, the pushing machine: output terminal is connected with the AC signal generator XXFQ of solenoid X and the signal receiver TXJQ that input terminus is connected with solenoid T, the output terminal that is arranged on the coke guide is connected with the AC signal generator LXFQ of solenoid LT and the signal receiver LXJQ that input terminus is connected with solenoid LX, the output terminal of signal receiver LXJQ links to each other with the control end of AC signal generator LXFQ, and the output terminal of the signal receiver TXJQ on the pushing machine links to each other with the control signal input terminus of pushing ram controller TGKQ.Signal receiver LXJQ on the coke guide is provided with and plucks the fire door signal input part and lead burnt gate signal input terminus.

During use, AC signal generator XXFQ on the quenching car does not stop sends AC signal, solenoid X produces magnetic field, with No. 10 coking chambers is example, when quenching car moves to coking chamber No. 10 along its orbit, because the action of a magnetic field that solenoid X produces, be arranged on the quenching car orbit solenoid X10 corresponding and produce induced currents with No. 10 carbonization chamber positions, the solenoid LX10 that forms series loop with solenoid X10 produces magnetic field; Have only when coke guide when its orbit moves to No. 10 coking chambers, the magnetic field of solenoid LX ability inductive electromagnetic coil LX10 produces induced current, at this moment, expression coke guide, quenching car have arrived specified location, signal receiver LXJQ receives electric current to be changed, and through plucking the fire door signal input part and leading burnt gate signal input terminus collects pluck fire door signal ZM and lead burnt gate signal DS, output control signal control coke guide signal generator LXFQ sends AC signal, and solenoid LT produces magnetic field; Solenoid LT10 senses the magnetic field that solenoid LT produces, and produces induced current, and the solenoid T10 that forms series loop with solenoid LT10 produces magnetic field; Have only when pushing machine when its orbit moves to No. 10 coking chambers, the magnetic field that solenoid T could inductive electromagnetic coil T10 produces induced current, signal receiver TXJQ receives electric current to be changed, output control signal control pushing ram controller TGKQ action.Promptly when pushing machine, coke guide, quenching car pushing machine arrive same coking chamber specified location, pushing ram controller TGKQ could remove the self-locking to pushing ram, otherwise the pushing machine driver can not operate pushing ram carries out coke pushing, has guaranteed accurate location, operational safety.Described AC signal generator, signal receiver are existing known products, can be buied by the market; In addition, it is known for those skilled in the art with the collection of leading burnt gate signal to pluck the fire door signal, does not therefore describe in specification sheets.

The utility model is rational in infrastructure, and cost is low, and result of use is good, and the proofing unit failure rate is low, has guaranteed that wrong coke pushing can not take place, and definitely ensures the safety of coke oven and avoids red Jiao to land.
