Spread out and gets over, not completely in view of bolt quality or the fatigue strength of long-term work, therefore, in the engineering accident of some large sizes,
Most of is caused by these bolts, and the part major traffic accidents of automobile, wind-powered electricity generation tower crane is collapsed, and man lift's falls,
The accidents such as collapse of electric power pylon are too numerous to enumerate, lose huge, bring serious threat to the safety of life and property of the people.
The hidden danger of serious accident caused by the invention of this patent can effectively exclude the damage due to bolt or loosen.
Summary of the invention
To solve the above problems, the invention proposes a kind of device of early warning working bolt exception, it is tight by detection bolt
Soundness prevents great engineering accident.
A kind of device of early warning working bolt exception of the invention, including pressure acquisition module, processing module, communication mould
Block, terminal reminding module and power module, pressure acquisition module are connected with processing module, and processing module is connected with communication module,
Communication module is connected with terminal reminding module, power module respectively with pressure acquisition module, processing module, communication module and terminal
Reminding module connection, the normal work for other modules provide power supply；The power module uses compact lithium cell；Present invention peace
Between bolt and nut；
Pressure acquisition module is for detecting the pressure value that bolt is born, when pressure value is bigger, illustrate by securing objects and
Tautness is bigger between bolt, when pressure value is smaller, illustrates smaller by tautness between securing objects and bolt, bolt has occurred
It loosening, the bolt pressure value measured is sent to processing module by pressure acquisition module, and processing module is used to receive bolt pressure value,
And the pressure value received and preset pressure value are compared, if bolt pressure value be lower than preset value, send warning information to
Communication module, communication module issue warning signal after sending alerting signal, reminding module to receive alerting signal to terminal reminding module；
As the scheme that further limits of apparatus of the present invention, the pressure acquisition module is using strain chip pressure sensing
Device.
As the scheme that further limits of apparatus of the present invention, the pressure acquisition module is encapsulated in annular gasket,
Annular gasket is set on bolt, and when the present invention is used for securing objects, annular gasket is located at bolt head and by securing objects
Between.It is used to measure the pressure that bolt is born positioned at bolt head and by the pressure sensor between securing objects.
As the scheme that further limits of apparatus of the present invention, the device of the invention further includes for detecting power module voltage
Power detection module, power detection module connect with power module, and the output end of power detection module is connect with processing module.
The processing module first choice low-power consumption processing, the operating supply voltage value that power detection module will test are sent to processing mould
Block, processing module by the operating supply voltage received compared with preset voltage rating, when operating supply voltage be lower than specified electricity
When pressure, processing module communication module sends warning information to terminal reminding module；
As the scheme that further limits of apparatus of the present invention, wired or wireless communication module is can be selected in the communication module
It is connect with processing module, is used for remote radio communication.
As the scheme that further limits of apparatus of the present invention, the terminal reminding module includes display and voice prompting mould
Block.It more intuitively can effectively play reminding effect.
Beneficial effects of the present invention: the device of the invention is mounted on bolt and by between securing objects, pressure acquisition module
It detects bolt and is sent to processing module by by the pressure value of securing objects pressure, and by the bolt pressure value measured, handle mould
Warning information, if bolt pressure value is lower than preset value, is sent to communication module, communication module for receiving bolt pressure value by block
Alerting signal is sent to terminal reminding module, reminding module issues warning signal after receiving alerting signal；The present invention is easy to use,
It is not limited by use occasion, forewarning function can be played when bolt loosens.
Detailed description of the invention
Fig. 1 is a kind of structural block diagram of embodiment of the invention.
Fig. 2 is the structural block diagram of another embodiment of the present invention.
Fig. 3 is scheme of installation of the present invention.
Wherein: 1, bolt head；2, annular gasket；3, screw.
Specific embodiment
As shown in Figure 1, a kind of device of early warning working bolt exception, including pressure acquisition module, processing module, communication mould
Block, terminal reminding module and power module；Pressure acquisition module is connected with processing module, and processing module is connected with communication module,
Communication module is connected with terminal reminding module, power module respectively with pressure acquisition module, processing module, communication module and terminal
Reminding module connection, the normal work for other modules provide power supply；As shown in figure 3, the pressure acquisition module is packed
In annular gasket 2, annular gasket 2 is set on bolt, and when the present invention is used for securing objects, annular gasket 2 is located at bolt
Head 1 and by between securing objects.Positioned at bolt head 1 and by the pressure sensor between securing objects for measuring bolt institute
The pressure of receiving, when the screw 3 to match with bolt is normally tightened, pressure acquisition module collects current pressure value, in advance
It deposits in systems, as the preset value of the bolt pressure, in the long-term use, due to bolt quality problems or uses problem
Processing module issues warning information when the tautness of bolt being caused to be reduced to the 90% of the preset value of the bolt, sends out through communication module
It makes arrangements for his funeral and holds reminding module, reminding module issues warning signal after receiving alerting signal；Wired or nothing can be selected in the communication module
