Abstract
The utility model relates to a swift current early warning device is prevented to contact net operation car, including power, air switch, limit switch, delay relay and alarm unit, the power -on is crossed the main line and is linked to each other with limit switch, is equipped with air switch on the main line between power and limit switch, the alarm unit passes through the circuit and links to each other with limit switch, is equipped with delay relay between alarm unit and limit switch. When the device can shunt at the station, some stops etc. The condition produces the spontaneous remission in operation and the station etc. Warning contact net operation car conductor and driver guaranteed to discover in the very first time that contact net operation car alleviates to take the effectively measure of brakeing, contact prevention net operation car runaway causes serious consequence, ensures contact net operation car and personal safety.
Description
Technical field
The utility model belongs to railway repair apparatus technical field, is specifically related to the anti-slip prior-warning device of a kind of operation vehicle for contact wire.
Background technology
Locomotive kills engine in the station retention period and does not set up defences and slips, the as easy as rolling off a log generation runaway of locomotive squeezes the accident of bad track trouble, and when working locomotive driver and conductor neglects, there is no actv. alarm set, can not driver and conductor be reminded when vehicle is alleviated to make corresponding workaround, and easily occur safety misadventure.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art and provides the anti-slip prior-warning device of a kind of operation vehicle for contact wire, when this device can be shunt at station, generation such as situation such as some stop etc. is alleviated automatically in operation and station etc., operation vehicle for contact wire driver and conductor is reminded to guarantee to find that operation vehicle for contact wire is alleviated in the very first time, thus take effective brake measure, prevent operation vehicle for contact wire's runaway from causing serious consequence, guarantee operation vehicle for contact wire and personal safety.
In order to achieve the above object, the utility model adopts following technical scheme:
The utility model provides a kind of operation vehicle for contact wire anti-slip prior-warning device, comprises power supply, air switch, limit switch, slug relay and alarm unit; Described power supply is connected with limit switch by main line, and the main line between power supply and limit switch is provided with air switch; Described alarm unit is connected with limit switch by circuit, between alarm unit and limit switch, be provided with slug relay.
According to the anti-slip prior-warning device of above-mentioned operation vehicle for contact wire, described alarm unit is made up of master cock and alarm mechanism, and master cock is connected with alarm mechanism by circuit.
According to the anti-slip prior-warning device of above-mentioned operation vehicle for contact wire, described alarm mechanism comprises LED and loud speaker, and described LED flash for prompting is reported to the police, and described loud speaker is sounded a buzzer to point out and reported to the police.
According to the anti-slip prior-warning device of above-mentioned operation vehicle for contact wire, described limit switch is mechanical type spring retainer switch.
According to the anti-slip prior-warning device of above-mentioned operation vehicle for contact wire, described alarm unit is 2 groups, and two group alarm unit are connected in parallel on main line.
Compared with prior art, the beneficial effect that obtains of the utility model:
1. protective case is all installed additional in the utility model structural gap switch and slug relay, avoids daily touching; Power supply is provided by mobile generator, guarantees to use reliably; Limit switch is mechanical spring type, triggers limit switch action by brake cylinder piston push rod push rod; Combined aural and visual alarm is avoided operation vehicle for contact wire's panel cut out and easy adjustment attractive in appearance.
2. the utility model structure can in operation vehicle for contact wire shunting, when the situation generations such as point are alleviated automatically in operation and station etc., vehicle driver and conductor is reminded to guarantee to find that vehicle is alleviated in the very first time, thus take effective brake measure, prevent wagon running away from causing serious consequence, guarantee vehicle and personal safety.
3. the utility model structure is simple, reasonable in design, has broad application prospects.
Accompanying drawing explanation
Fig. 1 is the utility model structural principle schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
With reference to Fig. 1, the anti-slip prior-warning device of a kind of operation vehicle for contact wire, comprises power supply 1, air switch 2, limit switch 3, slug relay 4 and alarm unit 5; Described power supply 1 is connected with limit switch 3 by main line, the main line between power supply 1 and limit switch 3 is provided with air switch 2; Described alarm unit 5 is connected with limit switch 3 by circuit, is provided with slug relay 4 between alarm unit 5 and limit switch 3; Described alarm unit 5 is made up of master cock 51 and alarm mechanism 52, and master cock 51 is connected with alarm mechanism 52 by circuit, and alarm mechanism comprises LED and loud speaker, and described LED flash for prompting is reported to the police, and described loud speaker is sounded a buzzer to point out and reported to the police; Wherein, described limit switch is mechanical spring type switch, and alarm unit is 2 groups, and two group alarm unit are connected in parallel on main line.
Principle of work:
Limit switch is mechanical type spring retainer switch, is arranged on locomotive curb girder close to brake cylinder piston push rod stroke place.When brake-cylinder pressure is 0kpa, operation vehicle for contact wire is in relieved state, and limit switch is in closure state, and equipment subsequent conditioning circuit switches on power; When brake-cylinder pressure is less than 20kpa or brake cylinder piston push rod stroke is less than 70mm, limit switch action is closure state, switches on power, and equipment subsequent conditioning circuit switches on power.When brake-cylinder pressure is greater than 20kpa or brake cylinder piston push rod stroke is greater than 70mm, limit switch action is normally open, off device subsequent conditioning circuit power supply.
