The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model rail vehicle can make rail vehicle betransported normally on railway with Pneumatic brake systems and by the locomotive traction operation, or lean on the power system oneself of self to move, adopt motor vehicle braking system in both cases respectively and brake from the traveling brake system, the brake cylinder input end is provided with three-way change-over valve B15, and two branch roads of three-way change-over valve B15 link to each other with electro-pneumatic brake B01 and from the control system of walking respectively; Comprise air effect valve D01 from the walking control system, air effect valve D01 comprises two braking earthen pipes, and one braking earthen pipe 12 links to each other with three-way change-over valve B15, and another braking earthen pipe 14 links to each other with the end of the control system three-way change-over valve D05 that walks certainly; A branch road from walking control system three-way change-over valve D05 links to each other with pressure regulating valve D04, pressure regulating valve D04 links to each other with total reservoir, from another branch road of walking control system three-way change-over valve D05 and be connected with braking electropneumatic valve D10, pressurize electropneumatic valve D11 and alleviate electropneumatic valve D12, braking electropneumatic valve D10 and pressurize electropneumatic valve D11 all link to each other with the input end of pressure regulating valve D04, alleviate electropneumatic valve D12 and are communicated with atmosphere.Wherein motor vehicle braking system can adopt the brake of existing rolling stock main flow, to satisfy the demand of transporting and being pulled operation, motor vehicle braking system changes according to train tube pressure or the control circuit power on/off changes, and drives 104 type electro-pneumatic brake B01, changes thereby drive brake-cylinder pressure; From the walking control system is to increase three-way change-over valve B15, air effect valve D01, walk control system three-way change-over valve D05, pressure regulating valve D04 and braking electropneumatic valve D10, pressurize electropneumatic valve D11 and alleviate electropneumatic valve D12 certainly in motor vehicle braking system, is the three-way change-over valve that is arranged in the control system of walking from the control system three-way change-over valve D05 that walks wherein.
When rail vehicle is pulled operation as vehicle, three-way change-over valve B15 is placed its parking stall, the braking earthen pipe of 104 type electro-pneumatic brake B01 is communicated with the rail vehicle brake cylinder, cut off the path of braking earthen pipe 12 and brake cylinder among the air effect valve D01, the braking of rail vehicle, alleviation are controlled by 104 type electro-pneumatic brake B01;
When rail vehicle as when traveling move, three-way change-over valve B15 is placed this parking stall, open the path of braking earthen pipe 12 and brake cylinder among the air effect valve D01, cut off the braking earthen pipe of 104 type electro-pneumatic brake B01 and the path of rail vehicle brake cylinder.The braking of rail vehicle, alleviate pneumatically valve D01 control.The action of air effect valve D01 is pneumatically braked earthen pipe 14 controls in the valve.
At the needs glancing impact, press stop button, braking electropneumatic valve D10 gets, pressure air through pressure regulation enters into air effect valve D01 by braking electropneumatic valve D10, make rail vehicle produce brake action, determine the pressure of brake cylinder or determine graduated application according to the time that touches the button according to the number of times that touches the button; When rail vehicle need be alleviated, press the alleviation button and make the pressure air of braking earthen pipe 14 in the air effect valve discharge the alleviation of rail vehicle brake cylinder by alleviating electropneumatic valve D12.Can realize the graduated release of rail vehicle braking repeatedly by alleviating button.
Pressurize electropneumatic valve D11 has three effects, the one, after rail vehicle being implemented the fixed point braking by braking electropneumatic valve D10, press pressurize electropneumatic valve D11, make the airline of pressure regulating valve D04 and the effect pipe normal open of air effect valve D01, guarantee can not cause the alleviation of rail vehicle because the effect pipe pressure leaks.The 2nd, when chance failure appears in braking electropneumatic valve D10, can press the pressurize button, make pressurize electropneumatic valve D11 dead electricity, make the effect pipe that enters air effect valve D01 through the pressure air of pressure regulation fast, rail vehicle produces brake action.The 3rd, from traveling brake system accident dead electricity the time, also can produce brake action.
It is as follows that its electropneumatic valve gets dead electricity:
? Braking Alleviate Pressurize (promptly)
The braking electropneumatic valve Get electric Dead electricity Dead electricity
Alleviate electropneumatic valve Dead electricity Get electric Dead electricity
The pressurize electropneumatic valve Get electric Get electric Dead electricity
Under the traveling operating mode, if when the electropneumatic brake system can not operate, the control system three-way change-over valve D05 that walks certainly can be placed urgent position rapidly, guarantee that rail vehicle can produce brake action immediately, to guarantee safety.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
