One, the motor train unit of this device being installed are connected by locomotive to be hung when being used for transportation or rescue, and the train tube pressure of locomotive converts corresponding current signal 0～10bar pressure into corresponding to 4～20mA in proportion through the sensor that pulls in the device.This car BCU converts this signal into corresponding train braking or alleviates instruction, and is transferred to each car of train through train network, in order to realize braking or alleviate synchronously, accurately control.
When two, other trains of motor train unit rescue of this device being installed, can realize the alleviation and the emergency braking function of train.This moment, total wind was adjusted into train pipe level pressure through pressure regulating valve, again through electromagnetic valve to being filled wind by the train pipe of breakdown train.When starting danger button or put brake-applying handle in urgent position; The safe loop outage of motor train unit; Thereby cause pulling electromagnetic valve outage in the device, train tube pressure is through the piston valve row atmosphere of big discharge capacity, thereby realization comprises by the emergency braking of the permutation car of tow lift.
The utility model provides a kind of module that pulls that is applied to EMU, has realized safety, fast traffic and the rescue of motor train unit, simultaneously can be in order to realize other trains of rescue.
Description of drawings
Above-mentioned and other characteristic of the utility model will be through becoming clearer with reference to accompanying drawing to the description of the detailed example property embodiment of the utility model, wherein:
Fig. 1 is that the utility model high speed railway motor train unit brake system pulls the device schematic diagram of gas circuit.
Fig. 2 is that the utility model high speed railway motor train unit brake system pulls device embodiment systematic schematic diagram.
The specific embodiment
Below will more comprehensively describe the utility model with reference to the accompanying drawing that shows the utility model exemplary embodiment.But the utility model can be with multiple multi-form enforcement, and the exemplary embodiment that should not only limit to here to be set forth is constructed.Certainly, it is in order to make this announcement more comprehensively with complete that these exemplary embodiments are provided, and can fully pass on the scope of the utility model to those skilled in the art.In the accompanying drawing, for the sake of clarity, device size and relative size possibly be exaggerated.
Below, will be with reference to accompanying drawing illustrated in detail the utility model.
With reference to Fig. 1, Fig. 1 is that the utility model high speed railway motor train unit brake system pulls the device schematic diagram of gas circuit.
As shown in Figure 1, the utility model high speed railway motor train unit brake system pulls device, and its composition comprises pressure sensor 01, electromagnetic valve 04, pressure switch 05, reducing valve 06, piston valve 07, precontrol valve 08, filter 11 and test port 12.
Preferably, brake system pulls device and is included in the electromagnetic valve 04 and the precontrol valve 08 that is used for air draft that are used to fill wind that is set up in parallel on the circuit, and electromagnetic valve and precontrol valve are associated with the emergency braking loop of guideway vehicle.
The pressure sensor 01 that brake system pulls device is connected with train network with the vehicle pipe of guideway vehicle, and the brake system sensor 01 that pulls device converts the pressure of vehicle pipe in proportion into electric signal and exports train network to.Specifically, pressure sensor 01 train tube pressure of can sampling, and electric signal of conversion output in proportion.
Brake system pulls device and can be disconnected to be connected with the emergency braking loop of vehicle via pressure switch 05.Pressure switch 05 can be associated with the danger button of train or the urgent position of brake-applying handle.Can break off train emergency braking loop through pressure switch, the control of precontrol valve of electromagnetic valve and air draft of filling wind simultaneously is relevant with train emergency braking loop.
The train pipe is connected with piston valve with blast main, and blast main and piston valve are opened or closed in response to the getting electricity condition of electromagnetic valve.It is the pressure regulating valve of level pressure that blast main is connected with the pressure control that is used for blast main,, can control the train tube pressure of output level pressure that is.
With reference to the accompanying drawings 2, shown in Figure 2 is the utility model case study on implementation.With reference to Fig. 2 the utility model and embodiment thereof are done further to specify, but the utility model is not limited to given example.
Under the train normal operation, pull device and do not work, can turn-off plug door B51 and B52 this moment and occur to avoid abnormal condition such as leakage, misoperation.
When if these motor train unit fault needs the locomotive rescue, need open this moment and cut off plug door B51 and B52.Can through check valve B53 to motor train unit fill wind from the pressure of locomotive train pipe this moment so that train obtain braking and auxiliary device use the wind demand.Pull simultaneously device electromagnetic valve 04 dead electricity and precontrol valve 08 electric, make electromagnetic valve 04 can not fill wind and make piston valve 07 be in close stance simultaneously the train pipe.
This moment, the pressure variation of locomotive train pipe converted current signal in proportion through pressure sensor 01; After this car brak control unit B01 receives this signal; Be converted into a cooresponding braking or alleviate instruction; And be transferred to each car through train network, and the cooresponding brake-cylinder pressure of brak control unit control output of per car, thus realize the braking or the alleviation of train.If locomotive is implemented emergency braking, pull unit internal pressure switch 05 when detecting train tube pressure and be lower than 4.0bar, the train safe loop be will break off, and electromagnetic valve 04 and precontrol valve 08 dead electricity caused, thus the emergency braking of realization redundancy.
If when needing these motor train unit in case of emergency to rescue other trains, need open equally and cut off plug door B51 and B52.Can realize being alleviated and the emergency braking effect through pulling device this moment by the wind that fills of tow lift.During normal the operation, electromagnetic valve 04 and precontrol valve 08 all get electric, and blast main pressure fills wind to level pressure through pulling device to the train pipe.Need glancing impact this moment; Can only realize the emergency braking of permutation car through the urgent position of train danger button or brake-applying handle; This moment safe loop dead electricity; Make all dead electricity of electromagnetic valve 04 and precontrol valve 08, thereby stop filling wind and train tube pressure being arranged atmosphere fast the train pipe through the piston valve 07 of big discharge capacity.Thereby realize the emergency braking of permutation car.Under this operating mode, pressure switch 05 has equally breaks off the function that safe loop is implemented emergency braking.
More than be explanation, and should be interpreted as restriction the utility model the utility model.Though described the embodiment of the utility model, it will be understood by those skilled in the art that under the situation of the novel teachings that substantially do not break away from the utility model and advantage, can carry out multiple modification to exemplary embodiment.Therefore; Be appreciated that; More than be explanation, be not limited to described certain exemplary embodiments, and will be intended to be included in the scope of accompanying claims modification and other exemplary embodiment of disclosed exemplary embodiment and should not be interpreted as to the utility model.
