Abstract
The invention relates to a locomotive pantograph fault protecting device which comprises a pantograph lifting electromagnetic valve, a pantograph lifting air path, a one-way valve and a pressure detecting switch. The air inlet of the one-way valve is connected to the pantograph lifting air path, and the air outlet thereof is connected with a pantograph head fault pressure relief air path. The pressure detecting switch is connected to the pantograph head fault pressure relief air path. An isolating electromagnetic valve is disposed between the air outlet of the one-way valve and the pantograph head fault pressure relief air path. When the air pressure of the pantograph head fault pressure relief air path is lower than a set value, the pressure detecting switch controls on and off of the pantograph lifting electromagnetic valve. When the air pressure of the pantograph head fault pressure relief air path is lower than the set value and the pantograph descends, the pantograph lifting air path is turned off. If pantograph lifting needs to be recovered, the isolating electromagnetic valve is turned off, and the pantograph lifting electromagnetic valve is turned on. By the locomotive pantograph fault protecting device, main air leakage of a vehicle can be prevented during automatic pantograph descending, and safety and reliability are increased; the leaking pipeline can be isolated after automatic pantograph descending, pantograph lifting can be achieved again, practicality of the vehicle can be increased, and rescuing probability of the vehicle can be lowered.
Description
Technical field
The present invention relates to a kind of motorcycle pantograph failure protecting device and control method, belong to locomotive technology field.
Background technology
The pantograph of city rail vehicle and electric locomotive is typically equipped with automatic bow-lowering device at present, when pantograph and contact system occur extremely to contact, automatic bow-lowering device can guarantee that pantograph departs from contact system fast and effectively, thereby has guaranteed that pantograph and contact system avoid damaging.But after pantograph falls by automatic bow-lowering device, train main air pipeline will continue release by bow leak point, makes train in unsafe condition.In addition,, if not to pantograph reparation rising bow again, can only be parked on circuit and wait for rescue, this can have a strong impact on the normal operation of other trains.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of motorcycle pantograph failure protecting device method is provided.
The object of the present invention is achieved like this: a kind of motorcycle pantograph failure protecting device; comprise rising bow electromagnetic valve and rising bow gas circuit, check valve and pressure detection switch; the admission port of described check valve is connected to rising bow gas circuit; air extractor duct is connected to bow fault and unloads pressure gas channel; pressure detection switch is connected to bow fault and unloads pressure gas channel; it is characterized in that unloading between pressure gas channel an isolation solenoid valve being set in described check valve air extractor duct and bow fault, pressure detection switch is controlled the shutoff of rising bow electromagnetic valve when bow fault is unloaded pressure gas channel air pressure lower than setting value.
A control method for above-mentioned motorcycle pantograph failure protecting device, is characterized in that taking the following step:
Bow falls in automatic fault
F. pantograph is when normal rising bow state, and isolation solenoid valve is in on-state;
G. detect bow fault and unload the air pressure of pressure gas channel;
When the air pressure that H. unloads pressure gas channel when bow fault is fallen lower than setting value, pantograph, turn-off rising bow electromagnetic valve;
Recover rising bow
I. turn-off isolation solenoid valve;
J. open rising bow electromagnetic valve.
The solution of the present invention can automatically be cut off air main and unload being connected of pressure gas channel with bow fault when there is automatic bow-lowering, has guaranteed that vehicle main air is not leaked, and has increased the safe reliability of vehicle; Can after automatic bow-lowering, isolate leakage line, can realize rising bow again, increase the availability of vehicle, reduce vehicular rescue probability; Complete function, integrated level is high, is beneficial to and installs and maintenance.
Accompanying drawing explanation

In figure, be labeled as: 1-rising bow electromagnetic valve, 2-rising bow gas circuit, 3-check valve, 4-pressure detection switch, 5-check valve inlet, 6-check valve air extractor duct, 7-bow fault is unloaded pressure gas channel, 8-isolation solenoid valve.
The specific embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1; the motorcycle pantograph failure protecting device of the present embodiment comprises rising bow electromagnetic valve 1 and rising bow gas circuit 2, check valve 3 and pressure detection switch 4; the admission port 5 of described check valve 3 is connected to rising bow gas circuit 2; air extractor duct 6 is connected to bow fault and unloads pressure gas channel 7; pressure detection switch 4 is connected to bow fault and unloads pressure gas channel 7, and described check valve air extractor duct 6 and bow fault are unloaded an isolation solenoid valve 8 is set between pressure gas channel 7.
Referring to Fig. 2 in detail, the control method of the present embodiment motorcycle pantograph failure protecting device is described in detail.
Bow falls in automatic fault
Pantograph is when normal rising bow state, and isolation solenoid valve 8 is in on-state.When bow fault, unload pressure gas channel 7 and leak to setting value when following, the contact of pressure detection switch 4 " 1; 2 " conducting, relay K A1 coil obtains electric, and KA1 normally closed contact " b1, b2 " is opened, thereby disconnected rising bow instruction output, rising bow instruction disconnects rising bow electromagnetic valve 1 dead electricity that it is controlled, and rising bow electromagnetic valve 1 turn-offs, and has stoped vehicle main air to leak.
Recover rising bow
After isolation solenoid valve 8 inputs effectively, relay K A3 coil obtains electric, KA3 normally closed contact " b1, b2 " disconnect, isolation solenoid valve 8 dead electricity, pressure gas channel 7 is unloaded in its mechanics action, while KA3 normally closed contact " b1, b2 " disconnect and cause KA2 coil losing electricity, relay K A2 open contact " k1, k2 " open, make relay K A1 coil losing electricity, be connected to the KA1 normally closed contact " b1 in pantograph rising bow instruction output, b2 " by closure, rising bow instruction just can be exported to rising bow electromagnetic valve 1 by actv., open main air pipeline and fill wind to rising bow gas circuit 2, realize rising bow.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
