Abstract

The utility model discloses an automatic barricade alarming device for railway crossing which is composed of a circuit part and a mechanical part. The mechanical part is a device for barricading, comprising two upright rods, two transverse rods, a motor, a driven wheel and a transmission steel cable, and the circuit part is composed of an inducer, an inertia switch, a controller, an acousto-optic circuit, etc. The inducer is connected with the inertia switch, and the inertia switch is in parallel connected with a controller circuit, a sound circuit and an optical circuit. The utility model can effectively solve the safety problem of unwatched crossings, and it has the advantages of simple structure, low production cost and easy popularization and application.

Description

The level crossing warning device of placing obstacles automatically

Affiliated technical field: the utility model relates to a kind of device of placing obstacles at the unmanned intersection alarm of railway that is exclusively used in.

Background technology: railway has many big and small highways, intersection along the line, promptly so-called level crossing.The grade separation road junction that the magnitude of traffic flow is bigger in the city, in the rural area, particularly remote districts the level crossing mostly be the level crossing road junction, wherein the overwhelming majority is the unmanned road junction that nobody guards.Owing to lack the warning means that actv. can forecast train passage, add all multifactor influences such as railway line situation, buried natural environment and climate condition, various pernicious traffic accidents happen occasionally in the level crossing, cause tremendous loss, the safe operation that also jeopardizes train simultaneously not only for passing people's lives and properties.Along with railway repeatedly raises speed, this situation is more and more outstanding.ZL96218796.8, ZL94218953.1 are the level crossing warning device in the prior art at present, but these warning device structures are all very complicated, and cost is also corresponding higher, is not easy to apply.

Summary of the invention: the purpose of this utility model promptly be to design a kind of be exclusively used in the unmanned road junction forecast of railway train passage, and be provided with automatically roadblock warning device.

The technical solution of the utility model is:

The utility model parallel circuit and mechanical two parts.

Mechanics is the device of placing obstacles, form by two vertical rods, two cross bars, motor, flower wheel, shackle line etc., two vertical rods are divided into crossing, rail both sides, top or bottom every vertical rod all are equipped with an electrical motor, fix a driving wheel on the output shaft of electrical motor, in vertical rod, one flower wheel is installed, is enclosed steel rope around one between driving wheel and the flower wheel away from the other end of electrical motor; Cross bar is fixed on the steel rope, and can move up and down with the rotation of steel rope; One contact knife is arranged on the steel rope, a travel switch respectively is set in the upper and lower of vertical rod, descending or when being up to assigned address when cross bar, contact knife contacting travel switch, motor promptly shuts down, and cross bar is static;

Circuit part is a control setup, is made up of inductor, time-delay switch, controller and acousto-optic circuit etc.; Inductor links to each other with time-delay switch, and time-delay switch also connects controller circuitry, acoustic-electric road and optical circuit;

During work, inductor sends to time-delay switch with the signal that train arrives, and circuit is connected: acoustical signal work---report to the police; Optical circuit work---send out a warning; Control circuit work---electrical motor rotates; The drive cross bar moves down, when cross bar moves down into certain position, and the contact knife contact lower stroke switch on the steel rope, motor stops operating, and cross bar stops the crossing;

After train sailed out of four corners, time-delay switch was opened, and acousto-optic circuit disconnects, and loudspeaker stop to report to the police, and red light goes out.When time-delay switch was opened, another circuit was connected, and the motor backward rotation drives on the cross bar and moves, and moves on to certain position on cross bar, the contact knife contact upper stroke switch on the steel rope, and motor promptly stops operating.

Adopt above-mentioned measure, can effectively solve the safety problem at unmanned guard crossing.And the utility model is simple in structure, and productive costs is extremely low, easily applies.

Description of drawings:

Fig. 1 is the structure diagram of the utility model mechanics;

Fig. 2 is a circuit block diagram of the present utility model.

The specific embodiment:

As shown in the figure: the top of vertical rod 1 or bottom are equipped with an electrical motor 3, fix a driving wheel 7 on the output shaft of electrical motor 3, away from the other end of electrical motor one flower wheel 6 are installed in vertical rod, enclose steel rope 8 around one between driving wheel 7 and the flower wheel 6; Cross bar 2 is fixed on the steel rope 8, and can move up and down with the rotation of steel rope 8; One contact knife 9 is arranged on the steel rope 8, a contact switch respectively is set in the upper and lower of vertical rod, descending or when being up to assigned address when cross bar 2, contact knife 9 contacting travel switches, motor 3 can stop operating;

During work, inductor sends to time-delay switch with the signal that train arrives, and circuit is connected: acoustical signal work---report to the police; Optical circuit work---send out a warning; Control circuit work---electrical motor rotates; The drive cross bar moves down, when cross bar moves down into certain position, and the contact knife 9 contact lower stroke switch 4 on the steel rope, motor 3 stops operating, and cross bar 2 stops the crossing;

After train sailed out of four corners, time-delay switch was opened, and acousto-optic circuit disconnects, and loudspeaker stop to report to the police, and red light goes out.When time-delay switch was opened, another circuit was connected, and motor 3 backward rotation drive on the cross bar 2 and move, and move on to certain position on cross bar 2, the contact knife 9 contact upper stroke switch 5 on the steel rope, and motor 3 promptly stops operating, and is outstanding on the cross bar 2.
