Description
Technical field
The present invention relates to rail clip failure detection field, is lost more particularly, to a kind of energy automatic warning track traffic fastener
The bolt of effect.
Background technology
In railway and the track structure of urban track traffic, fastener be fixed rail on sleeper or track plates, keep rail
The important component of road track geometry.Fastener is large number of, type is various, but provides enough buckle press and firm to realize
Stability, its vital part are bolts.Fastening bolt can be divided into for the bolt with screw head of anchoring fastener and for fixing
The major class of nut bolt two of fastening elastic rod.Fastener in use, bolt in train load transmission, temperature and humidity, rail
Under the influence of the factors such as road circuit, it may appear that screw head and screw rod fracture, bolt looseness, nut loosening, packing ring fracture etc. are directly damaged
Wound, causes fastener to fail.Or when fastening elastic rod fracture, bolt spring failure, although bolt is in good condition, fastener is in itself
Failed because losing buckle press or elasticity.The failure of this two major classes fastener is most common in current rail and urban track traffic
Phenomenon.In the failure of these fasteners, bolt and fastener component such as spring, packing ring, spring are contacted not close or even no longer existed.
At present, mainly by manual inspection, efficiency is low and very passive, can not more be transported in train for the detection of contacting piece state
Checked when battalion.Chinese patent CN203063961U discloses a kind of railway spring-fastener tightening state and checks dolly automatically, including
Small rail car, linear structural laser sensor, photoelectric encoder, GPS, synchronization control circuit, embedded computer and electricity
Source device, small rail car is across on the rail of both sides, and linear structural laser sensor is set on small rail car, and photoelectric encoder is arranged on
On the central shaft of small rail car wheel, the antenna of GPS is arranged on small rail car, receiver is arranged on Synchronization Control electricity
In road, synchronization control circuit, embedded computer and supply unit are sequentially arranged in small rail car.The dolly can realize railway
The automatic detection of elastic bar fastener tightening state and alarm, but the vehicle structure is complicated, and cost is higher, and use is also inconvenient.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of low manufacture cost, make
The bolt to be failed with convenient energy automatic warning track traffic fastener.
The purpose of the present invention can be achieved through the following technical solutions：
It is a kind of can the failure of automatic warning track traffic fastener bolt, including packing ring, the screw head that matches with packing ring or spiral shell
Fastener failure warning circuit is provided with cap and the screw rod being connected with screw head or nut, the screw head or nut, the fastener loses
Effect warning circuit includes battery, normally closed switch and LED, and the LED is exposed to screw head or nut surface, the battery, normal
Make and break pass and LED pass sequentially through electric wire and are linked to be primary Ioops；It is normally closed to open when screw head or nut are tightened, completely attached to packing ring
Close and close, the loop is in open circuit, and when screw head or nut loosen, completely disengage or be partially disengaged with packing ring, normally closed switch is beaten
Open, the loop is in path, and LED is lighted, and realizes automatic warning.
Be provided with the screw head or nut for placing battery and the groove of normally closed switch, the wire casing for placing electric wire and
For placing the perforate of LED, the groove, perforate are interconnected by wire casing.
The groove and wire casing are located at screw head or nut bottom surface.
The groove is provided with two.
The wire casing is around screw head or nut one week.
The diameter of the wire casing is less than the diameter of screw head or nut, and more than the diameter of screw rod.
The perforate on screw head or pane or top surface, from side or the surface of top surface to screw head or nut inside
Extension, until being connected with wire casing.
The perforate is individual provided with 1~(n-1), wherein, n is screw head or the side number of nut.
The LED is the lamp of other any colors in addition to red light.
The battery is button cell.
Compared with prior art, the present invention is directly using fastener existing anchor bolt and spring bolt, in anchor bolt
Screw head and spring bolt nut in open up wire casing, groove, and include battery, normally closed switch and LED in lateral opening hole, installation
The fastener failure warning circuit of lamp, in the case where screw head or nut are tightened and packing ring is closely connected, normally closed switch closes, and circuit is in
Open circuit, LED do not work；When screw head or nut loosen, completely disengage or be partially disengaged with packing ring, normally closed switch is opened, circuit
In path, LED is lighted, so as to the failure of automatic warning fastener.This causes fastening bolt both to have the fixation work(of design requirement
Can, while installed again from carrier state alarm function as common fastening bolt, manual inspection is saved, improves fastener failure
Recall rate.The present invention has advantages below：
1. utilize the existing bolt of fastener；2. easy to process, installation method is identical with common fastening bolt；3. cost of manufacture
It is relatively low；LED is shinny when 4. fastener fails, automatic warning；5. the automatic warning of all fastener states can be realized.
