Background technology
In the track structure of railway and urban track traffic, fastener be fixing rail on sleeper or track plates, keep the vitals of track geometry.Fastener One's name is legion, type are various, but in order to realize providing enough buckle presses and firmly stability, its vital part is bolt.Fastening bolt can be divided into the bolt for the band spiral shell head of anchoring fastener and the large class of the nut bolt two for attachment fastener spring.In the use of fastener, bolt, under the impact of the factors such as train load transmission, temperature and humidity, track circuit, there will be spiral shell head and screw rod fracture, the coup injury such as bolt looseness, nut loosen, packing ring fracture, causes fastener to lose efficacy.Or when fastening elastic rod fracture, bolt spring lost efficacy, although bolt is in good condition, fastener itself lost efficacy because losing buckle press or elasticity.It is modal phenomenon in current rail and urban track traffic that this two large class fastener lost efficacy.During these fasteners lost efficacy, bolt and fastener component such as spring, packing ring, contacting of spring did not closely even no longer exist.
At present, the detection of contacting piece state is mainly by manual inspection, and inefficiency and very passive, more cannot check when train operation.Chinese patent CN203063961U discloses a kind of railway spring-fastener tightening state automatic inspection dolly, comprise small rail car, linear structural laser sensor, photoelectric encoder, GPS, synchronization control circuit, embedded computer and supply unit, small rail car is across on the rail of both sides, on linear structural laser sensor setting small rail car, photoelectric encoder is arranged on the central axis of small rail car wheel, the antenna of GPS is arranged on small rail car, receiver is arranged in synchronization control circuit, synchronization control circuit, embedded computer and supply unit are arranged in small rail car successively.This dolly can realize automatic detection and the warning of railway spring-fastener tightening state, but this vehicle structure is complicated, and cost is higher, uses also inconvenient.
Summary of the invention
Object of the present invention is exactly can the bolt that lost efficacy of automatic warning track traffic fastener in order to what overcome that defect that above-mentioned prior art exists provides a kind of cost of manufacture low, easy to use.
Object of the present invention can be achieved through the following technical solutions:
The bolt that a kind of energy automatic warning track traffic fastener lost efficacy, the spiral shell head comprise packing ring, matching with packing ring or nut and the screw rod be connected with spiral shell head or nut, fastener inefficacy warning circuit is provided with in described spiral shell head or nut, described fastener inefficacy warning circuit comprises battery, normally closed switch and LED, described LED is exposed to spiral shell head or nut surface, and described battery, normally closed switch and LED are linked to be primary Ioops by electric wire successively; Tighten at spiral shell head or nut, when contacting completely with packing ring, normally closed switch closes, and described loop is open circuit, loosen at spiral shell head or nut, depart from completely with packing ring or part departs from time, normally closed switch is opened, and described loop is path, LED is lighted, and realizes automatic warning.
Be provided with in described spiral shell head or nut for placing battery and normally closed switch groove, for placing the wire casing of electric wire and the perforate for placing LED, described groove, perforate are interconnected by wire casing.
Described groove and wire casing are located at spiral shell head or nut bottom surface.
Described groove is provided with two.
Described wire casing is around spiral shell head or nut one week.
The diameter of described wire casing is less than the diameter of spiral shell head or nut, and is greater than the diameter of screw rod.
Described perforate is located on spiral shell head or pane or end face, from the side or the surface of end face extend, until be connected with wire casing to spiral shell head or nut inside.
It is individual that described perforate is provided with 1 ~ (n-1), and wherein, n is the side number of spiral shell head or nut.
Described LED is the lamp of other any colors except red light.
Described battery is button cell.
Compared with prior art, the anchor bolt that the present invention directly utilizes fastener existing and spring bolt, wire casing, groove is offered in the spiral shell head of anchor bolt and the nut of spring bolt, and at lateral opening hole, install and comprise the fastener inefficacy warning circuit of battery, normally closed switch and LED, tighten at spiral shell head or nut, closely connected with packing ring, normally closed switch closes, circuit is open circuit, and LED does not work; When spiral shell head or nut loosen, depart from completely with packing ring or partly depart from, normally closed switch is opened, and circuit is path, and LED is lighted, thus the inefficacy of automatic warning fastener.This makes fastening bolt both have the fastness function of designing requirement, simultaneously again from carrier state alarm function, installs the same with common fastening bolt, saves manual inspection, improves the recall rate that fastener lost efficacy.The present invention has the following advantages:
1. the existing bolt of fastener is utilized; 2. easy to process, mounting method is identical with common fastening bolt; 3. cost of manufacture is lower; 4. when fastener loses efficacy, LED was shinny, automatic warning; 5. the automatic warning of all fastener states can be realized.
