Abstract
The utility model discloses a kind of induction type time-delayed safe warning devices, including being mounted on the inductor, the cabinet, alarm that easily loosen beside parts；The inductor is mounted on cabinet, and corresponding with easy loosening parts axial position, inductor is connect with the alarm on cabinet, and alarm includes audible-visual alarm lamp, alarm time-delay mechanism.The utility model can monitor important fixing piece in mechanical equipment, find fixing piece loosening, dropping situations in time by alarm signal, improve observation accuracy, improve alarm accuracy, and exclusion security risk reduces the daily cumbersome review time.
Description
Technical field
The utility model relates to safety alarm devices, and in particular to a kind of induction type safety alarm device.
Background technique
Currently, fixed pin is used as assembly positioning in heavy mechanical equipment, guarantee the accuracy of position, fixed pin is once loose
Dynamic fall off can generate great safety accident.But the more narrow spaces in position of fixed pin safety, and fixed pin in big machinery
Quantity is more, and manual inspection is very difficult, and worker's task is heavy.
Utility model content
For above-mentioned problems of the prior art, the purpose of the utility model is to provide a kind of safety alarm device,
Important fixing piece in mechanical equipment is monitored, security risk is excluded.
The purpose of this utility model is achieved in that
A kind of induction type safety delay warning device, including being mounted on the inductor, the cabinet, alarm that easily loosen beside parts
Device；The inductor is mounted on cabinet, loosens the alarm company that parts axial position is corresponding, on inductor and cabinet with easy
It connects, alarm includes audible-visual alarm lamp, alarm time-delay mechanism.
Based on the above technical solution, the utility model can also do following improvement:
Further, the inductor includes close to switch S.
Further, the close switch S distance of reaction is 3~8mm.
Further, the close switch S distance of reaction is 5mm.
Further, there are also the time relays, intermediate relay for the alarm.
Compared with the existing technology, the utility model can monitor important fixing piece in mechanical equipment, by alarm signal and
The loosening of Shi Faxian fixing piece, dropping situations improve observation accuracy, improve alarm accuracy, and exclusion security risk is reduced daily
The cumbersome review time.
Detailed description of the invention
Fig. 1 is induction type safety delay warning device structural schematic diagram；
Fig. 2 is induction type safety delay warning device circuit diagram.
Specific embodiment
As shown in Fig. 1~2, a kind of induction type safety delay warning device easily loosens the sense on 1 side of parts including being mounted on
Answer device 2, cabinet 3, alarm；Inductor 2 is mounted on cabinet 3, corresponding with easy 1 axial position of parts that loosens, inductor 2 and case
Alarm connection on body 3, alarm include audible-visual alarm lamp, alarm time-delay mechanism.
Inductor includes close to switch S.
Preferably, close switch S distance of reaction is 3~8mm.
It further, is 5mm close to switch S distance of reaction.
Alarm further includes the time relay, intermediate relay.
It is with detected object when the detecting head close to switch S only proximate to mechanically direct without being carried out with component close to switch S
It contacts and manipulable position switch.In equipment running process, Yi Songdong parts 1 loosen or fall off, with 2 spacing of inductor
From close within the scope of switch S distance of reaction, triggering close to switch S, close switch S closure, intermediate relay coil KA and when
Between relay coil KT be powered, generate galvanomagnetic-effect, intermediate relay KA and time relay KT work, time relay KT exists
Closure is executed after obtaining input signal, input signal still has certain delay after disappearing, and delay time is 30s~30min, alarm
Lamp 4 lights, and 5 alarm of buzzer siren sounds, and continues to alarm, and worker is reminded to debug in time.
Easily loosening parts can be the parts such as fixed pin on big machinery, fixed block.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
