Description
Technical field
The present invention relates to railway security, the railcar of especially a kind of function that flown out with fracture loose alarming and anti-dropout
With bolt.
Background technology
The domestic and international rail vehicles no fracture of bolt or loose alarming function at present, designer's generally use
The method of increase bolt quantity ensures the safe handling of bolt connection parts.Under conventional operation condition, what bolt was subject to
Dynamic stress is smaller, and bolt is seldom broken, not too big potential safety hazard.
With the raising of China railways train running speed, the dynamic load that bolt is subject to becomes big, bolt fracture or loosening
Situation gradually increase, because train running speed is higher, the bolt that comes off is for line tower foundation facility and to line after it is broken
The safety belt for exercising train threatens.
The content of the invention
To overcome the defects of existing, the present invention proposes a kind of railway for the function that flown out with fracture loose alarming and anti-dropout
Vehicle bolt.
A kind of rolling stock bolt for the function that flown out with fracture loose alarming and anti-dropout, including hollow bolt, peace
Completely it is secured by bolts in alarm signal generator, the alarm signal generator at the top of hollow bolt, the hollow spiral shell
Hollow cavity is set inside bolt, safety line is arranged in bolt hollow cavity, wherein, hollow bolt bottom is fixed in safety line one end
Portion, the safety line other end are arranged inside alarm signal generator.
Wherein, first electrode and second electrode, the first electrode and second electrode are set inside alarm signal generator
Both sides bottom inside alarm signal generator is respectively arranged at, wherein, first electrode lower end sets resilient support pad.
Wherein, first electrode upper end sets pressing plate, sets through hole in the middle part of the pressing plate, safety line is fixed on pressure through through hole
Plate upper end.
Wherein, surface-mounted integrated circuit is set inside alarm signal generator, wherein, surface-mounted integrated circuit upper end sets wireless power
Transmitter, surface-mounted integrated circuit lower end set button cell, and the first electrode and second electrode connect surface-mounted integrated circuit respectively.
The mesh of the present invention is, by setting protective wire inside bolt, to realize for the protection work(after bolt fracture
Can, it can prevent break bolt from coming off to fly out.By setting protective wire inside bolt, the present invention is realized for bolt looseness
Defencive function afterwards, the further loose or dislocation of bolt can be prevented.Switch closure is driven to send using the protective wire of tensioned state
Alarm signal so that warning circuit is closed usually, is just closed in fracture or loosening, little power consumption, fracture alarm
Reliability is high.Protective wire alarm signal is tensed by end to send, alarm signal disappears after decontroling protective wire, it is possible to convenient
Confirm whether bolt alarm device state is normal, and it is overhauled so as to be implemented without demounting bolt can.
Brief description of the drawings
Fig. 1 is to be flown out the rolling stock bolt arrangement schematic diagram of function with fracture loose alarming and anti-dropout.
Fig. 2 be with fracture loose alarming and anti-dropout fly out function rolling stock bolt fracture when schematic diagram.
Embodiment
There is fracture loose alarming and anti-dropout to fly one kind provided by the invention with specific embodiment below in conjunction with the accompanying drawings
The rolling stock for going out function is described in detail with bolt.
Fig. 1 shows, a kind of have a fracture loose alarming and anti-dropout flies out the rolling stock bolt of function, including hollow
Bolt 1, safety line 2 and alarm signal generator 3, the alarm signal generator 3 are fixed on hollow bolt 1 by bolt 11 and pushed up
Portion, the inside of hollow bolt 1 set hollow cavity, and safety line 2 is arranged in the hollow cavity of bolt 1, wherein, safety line 2 one
The bottom of hollow bolt 1 is fixed at end, and the other end of safety line 2 is arranged inside alarm signal generator 3.
The inside of alarm signal generator 3 sets first electrode 8 and second electrode 9, the first electrode 8 and second electrode 9
The inside both sides bottom of alarm signal generator 3 is respectively arranged at, wherein, the lower end of first electrode 8 sets resilient support pad 10.
The upper end of first electrode 8 sets pressing plate 7, and the middle part of pressing plate 7 sets through hole, and safety line 2 is fixed on pressure through through hole
The upper end of plate 7.
The inside of alarm signal generator 3 sets surface-mounted integrated circuit 5, wherein, the upper end of surface-mounted integrated circuit 5 sets wireless power to send out
Emitter 6, the lower end of surface-mounted integrated circuit 5 set button cell 4, and the first electrode 8 and second electrode 9 connect surface-mounted integrated circuit respectively
5。
Safety line 2 is set inside hollow bolt 1, and bolt end sets alarm signal generator 3, when hollow bolt 1 is complete
When good, safety line 2 is in relaxed state, and alarm signal generator 3 is off, when fracture or pine occur for hollow bolt 1
When dynamic, safety line 2 is tightened, and alarm signal generator 3 closes, and sends alarm signal, while safety line 2 protects break bolt, keeps away
Exempt from breaking portion to come off, its further loose or dislocation can be avoided for loose bolts.
When hollow bolt 1 is intact, safety line 2 is in relaxed state, and first electrode 8 and second electrode 9 do not contact, entirely
Circuit is off, and signal generator is closed.
Shown in Fig. 2, when hollow bolt 1 is broken, safety line 2 is in tensioned state, and band dynamic pressure plate 7 oppresses first electrode 8
It is bonded with second electrode 9, closing of circuit, alarm signal is sent, and the wireless signal receiver that can be set onboard receives.
The bolt that safety line 2 plays a part of protection fracture simultaneously will not fly out.
The hollow bolt head lateral opening hole in, the present invention can realize the function of bolt looseness alarm, and protective wire leads to
Cross side opening to pass, be connected on a certain fixed position, such as other bolts, when bolt looseness, bolt head rotates, and causes to protect
Shield line is tightened, and is realized alarm and is prevented the effect of the further loose or dislocation of bolt.
Finally it should be noted that above example is only describing technical scheme rather than to this technology method
Limited, the present invention can above extend to other modifications, change, application and embodiment, and it is taken as that institute in application
There are such modification, change, application, embodiment all in the range of the spirit or teaching of the present invention.
