Description
Technical field
The present invention relates to monitoring field, specifically the anti-broken belt supervising device of a kind of chain belt of pig machine.
Background technology
Pig machine equipment is comprised of systems such as Molten iron chute, frames, the assembling of chain band, pig mold, driving wheel transmission device, driven pulley assembling and take-up device, spray cooling system, spraying system, the iron chute that falls, sled iron device, electric control systems.During cast iron, the molten iron that blast furnace process goes out is transported to the cast predetermined area with torpedo tank car or traction locomotive, makes the molten iron in fish torpedo ladle or hot-metal bottle be injected into continuously in the pig mold of pig machine through chute through tumbling.Pig mold is bolted on chain band, and the rotation of chain band drives pig mold shuttling movement.
Chain band is the special chain that drives pig mold motion, and the effect of axis is that a section carrier bar is coupled together and forms chain band, is the crucial attaching parts of chain band, is also the damageable zone of equipment.As a rule, the axis spot check position of pig machine is a lot, and chain band often has hundreds of and even thousands of axis spot check positions.Such as a centre-to-centre spacing is the chain band of 65 meters, on on-the-spot axis, just there are 320 spot check positions, the working strength of spot check is large, spot check inefficiency, and rely on naked eyes to be difficult to accomplish accurate spot check.In addition, in Cast Iron Production, the operation of equipment high temperature heavy load, on-the-spot high temperature, personnel cannot be near point inspection equipments, and on-site steam concentration is large, has a strong impact on personnel's sight line, thereby restricts the accuracy of artificial spot check.In addition, if one of them axis spot check position produces play, easily cause that axis is deviate from or phenomenon of rupture, whole piece chain band is disconnected and skid off, cause substantial equipment accident, affect whole ironmaking production, and repairing accident also needs to expend huge manpower and materials.
This technical problem for existing in prior art.
Summary of the invention
The technical problem to be solved in the present invention is, for above-mentioned technical problem, the technical scheme of the anti-broken belt supervising device of a kind of chain belt of pig machine is provided, this scheme is simple in structure, and can overcome that axis spot check position is many, the drawback of artificial spot check difficulty that the on-the-spot high temperature of spot check, spot check on-site steam concentration bring greatly, can realize the automatic detecting to axis, detection efficiency is high, and can strengthen the safety and reliability of equipment, also can reduce production costs simultaneously, reduce the input to manpower and materials.
In order to solve the problems of the technologies described above, the invention provides the anti-broken belt supervising device of following a kind of chain belt of pig machine, comprise chain band, chain band is provided with axis; The both sides of described chain band is respectively equipped with the alarm limit bit switch for spacing axis, after each alarm limit bit switch parallel connection, connects with alarm.
Wherein, alarm limit bit switch is installed respectively in both sides at every chain band of pig machine, be exclusively used in the position of monitoring axis, during use, between alarm limit bit switch and the spindle nose of axis, set certain security control size, once there is chain band axis play phenomenon in production process, no matter which end axis alters to, once axis play reaches certain distance, play axis just can be run into alarm limit bit switch in running, all can detect accurately by alarm limit bit switch, thereby the circuit at connection alarm place is reported to the police.
Between each alarm limit bit switch and alarm, be provided with a press button, each alarm limit bit switch and this press button and alarm are connected in series by wire respectively.Press button is in use in normally off, after warning for cutting off warning.
Each alarm limit bit switch is connected and is connected with alarm lamp by wire, and alarm lamp is arranged in the master-control room of pig machine.During alarm equipment alarm, alarm lamp is bright, thereby makes staff can obtain intuitively warning message, to handle it in time.
The quantity of described alarm lamp equates with the quantity of alarm limit bit switch, each alarm lamp alarm limit bit switch of connecting respectively, and each alarm lamp is connected in parallel.During use, alarm lamp is corresponding one by one with alarm limit bit switch, is not only convenient to staff and observes intuitively, and be convenient to the position that staff produces production accident by alarm lamp and locate fast, and then be convenient to deal with in time, reduces loss.
Described alarm lamp is incandescent lamp or LED lamp.
Described alarm adopts loudspeaker or warning alarm bell or audible-visual annunciator, and alarm is arranged in the master-control room of pig machine.
Described alarm limit bit switch adopts travel switch.
The quantity of described alarm limit bit switch is 4.
Compared with prior art, the invention has the advantages that:
(1) the present invention includes alarm and a plurality of alarm limit bit switch, and described alarm limit bit switch splits the both sides at chain band, and alarm limit bit switch is exclusively used in the position of monitoring axis, once axis is to its any one end play, and play reaches certain distance, axis just can be run into alarm limit bit switch in running, this can detect accurately by alarm limit bit switch, thereby connect the circuit at alarm place, report to the police in time, can effectively prevent the pig machine with that breaks, and this warning only need be rotated chain band can accomplish once enclosing, and detection efficiency is high and it is accurate to detect, not only can alleviate workman's labour intensity, increase work efficiency, and the drawback of the artificial spot check difficulty of can overcome that existing pig machine axis spot check position is many, the on-the-spot high temperature of spot check, spot check on-site steam concentration bringing greatly, realizes the automatic detecting to axis, reduces the input to manpower and materials, reduces production costs, can also strengthen the safety and reliability that chain band is used,
(2) the present invention includes alarm and a plurality of alarm limit bit switch, and after each alarm limit bit switch parallel connection, connect with alarm, thereby make the present invention have a plurality of spacing positions, and touch alarm limit bit switch on each spacing position, alarm all can send warning, uses flexibly;
(3) the present invention is provided with a press button between each alarm limit bit switch and alarm, press button, in use in normally off, once report to the police, can pass through the circuit at this press button breaking alarm place, make alarm stop alarm, thereby reduce noise pollution;
