Abstract
The present invention provides a kind of gunpowder explosion warning device monitored to forklift teeth based on angle strain trigger circuit, it includes：Gunpowder packet；The match board head being connect with gunpowder packet；Normally opened trigger circuit, including battery and normally opened induction switch, circuit is constituted with the match board head；Isolation is swung with the relative displacement of scraper bowl and teeth in the hole being arranged between scraper bowl and teeth, can be drivingly mechanically connected with the induction switch.The present invention between scraper bowl and teeth by being arranged isolation, when there is relative displacement between scraper bowl and teeth, isolation occurs to swing and be driven to switch to induction, normally opened induction switch is closed after swinging, trigger circuit is caused to be connected, to light match board head, ignites gunpowder packet and sound formation alarm occurs, forklift operating personnel is reminded to pay attention to taking measures；Relative displacement of the program only between scraper bowl and teeth is related, is not influenced by environmental factor, monitoring effect is good.
Description
Technical field
The invention belongs to forklift teeth to slide monitoring field, and in particular to one kind straining trigger circuit to forklift based on angle
The gunpowder explosion warning device that teeth is monitored.
Background technology
During loading ore, since bolt is broken, the teeth on scraper bowl falls off forklift frequent occurrence.Forklift is filling
During carrying ore, the teeth to fall off can be packed into mine car together with ore.If cannot find in time, the teeth that falls off can and
Ore is discharged into ore crusher together.Teeth is very hard, once into crusher, crusher can be stuck, and cause crusher
The damage of the components such as roller tooth and deceleration system, to cause great economic loss.Therefore the mounting design on forklift is needed to shovel
Tooth slides warning device, to find that teeth falls off in time, reminds construction personnel to take immediate steps, avoids causing great warp
Ji loss.
In the prior art, using industrial camera come the case where monitoring teeth, due to by weather conditions, air quality,
The vibration influence occurred in work progress, monitoring result are undesirable.
Invention content
The technical problem to be solved by the present invention is to：One kind is provided to supervise forklift teeth based on angle strain trigger circuit
Depending on gunpowder explosion warning device, do not influenced by environmental factor, monitoring effect is good.
The technical solution taken by the invention to solve the above technical problem is：One kind straining trigger circuit pair based on angle
The gunpowder explosion warning device that forklift teeth is monitored, it is characterised in that：It includes：
Gunpowder packet；
The match board head being connect with gunpowder packet；
Normally opened trigger circuit, including battery and normally opened induction switch, circuit is constituted with the match board head；
Isolation is swung with the relative displacement of scraper bowl and teeth in the hole being arranged between scraper bowl and teeth, with
The induction switch can be drivingly mechanically connected.
By said program, the trigger circuit is arranged in the circuit box body of waterproof, circuit box body be fixed on scraper bowl with
In hole between teeth.
By said program, in a protective case, protective shell is arranged in teeth side for the gunpowder packet and match board head setting
In slot.
By said program, the slot length is 1cm.
Beneficial effects of the present invention are：By the way that isolation is arranged between scraper bowl and teeth, when having between scraper bowl and teeth
When relative displacement, isolation occurs to swing and be driven to switch is induced, and normally opened induction switch is closed after swinging, and leads to triggering electricity
Road conducting ignites gunpowder packet and sound formation alarm occurs, prompting forklift operating personnel, which pay attention to taking, to be arranged to light match board head
It applies；Relative displacement of the program only between scraper bowl and teeth is related, is not influenced by environmental factor, monitoring effect is good.

Specific implementation mode
With reference to specific example and attached drawing, the present invention will be further described.
The present invention provides a kind of gunpowder explosion alarm dress monitored to forklift teeth based on angle strain trigger circuit
It sets, as shown in Figures 1 to 4, it includes：Gunpowder packet 5；The match board head 6 being connect with gunpowder packet 5；Normally opened trigger circuit, including electricity
Pond 7 and normally opened induction switch 3 constitute circuit with the match board head 6；Isolation 1, the hole being arranged between scraper bowl and teeth
In swung with the relative displacement of scraper bowl and teeth, can be drivingly mechanically connected with the induction switch 3.
In order to be protected to trigger circuit, the trigger circuit is arranged in the circuit box body 2 of waterproof, circuit box body
2 are fixed in the hole between scraper bowl and teeth.
In a protective case, protective shell is arranged in the slot of teeth side for gunpowder packet 5 and the setting of match board head 6.The present embodiment
The a length of 1cm of trough rim.
The present invention between scraper bowl and teeth by being arranged isolation 1, when there is relative displacement between scraper bowl and teeth, touches
Hair piece 1 swings certain angle to trigger position 1 ', which, which is driven, gives induction switch 3 so that induces switch 3 and swings centainly
Angle causes trigger circuit to be connected to 4 contact closure of contact for inducing position 3 ' and circuit, to light match board head 6, ignites fire
Pack 5 explodes, and the sound of big decibel forms alarm, and forklift operating personnel is reminded to pay attention to taking measures.Hear alarm, forklift
Operating personnel stop operation immediately, and construction personnel investigates the teeth of forklift one by one, then repair impaired bolt or shovel
Tooth.If teeth falls off, teeth and the bolt of fracture are searched out around scraper bowl, in order to avoid damaged into crusher.To protect
The reliability for demonstrate,proving the explosion prior-warning device, every 30 days should to the match board head of IC system, teeth side on teeth,
Gunpowder explosion device is checked, if it find that breakage should be replaced in time, in order to avoid when teeth falls off, cannot play alarm
Effect.
In the present embodiment, gunpowder packet 5 is small-sized gunpowder packet, and the sound for sending out big decibel pacifies device and human body
Entirely.In order to further improve the promptness of the explosion of gunpowder packet 5, match board head 6 is installation by adhering in gunpowder packet 5.In order to anti-
Only battery drain or damage, the present embodiment is in such a way that 2 batteries are in parallel.
Above example is merely to illustrate the design philosophy and feature of the present invention, and its object is to make technology in the art
Personnel can understand the content of the present invention and implement it accordingly, and protection scope of the present invention is not limited to the above embodiments.So it is all according to
According to equivalent variations or modification made by disclosed principle, mentality of designing, within protection scope of the present invention.
