Description
technical field:
the utility model relates to a kind of liquefied petroleum gas railway tanker brake equipment.
background technology:
at present, the brake mode that rail vehicles adopts comprises Block brake, disc braking, hand brake etc.Cylinder iron or watt shape slipper made of other materials, in the time of braking, hold wheel tread tightly, by friction, wheel is stopped operating.In this course, brake equipment will change huge kinetic energy into heat energy and is melt among atmosphere.And the quality of this braking effect but depends primarily on the dissipation capability of frictional heat energy.While using this brake mode, brake shoe frictional area is little, and most of thermal load is born by wheel.Train speed is higher, and when braking, the thermal load of wheel is also larger.As brake shoe cylinder iron, temperature can make brake shoe fusing; Even if adopt more advanced composite brake shoe, temperature also can be up to 400 ~ 450 ℃.In the time that Wheel Tread Temperature is increased to a certain degree, will make tread wear, crackle or peel off, both affect and also affected traffic safety service life.The deficiency of disc braking is that wheel tread does not have the mill of brake shoe to scrape, and will make wheel rail adhesion worsen; Brake disc increases unsprung weight and impact shock, consumption tractive output in service.Hand brake is take manpower as braking prime power, handles control with rotation direction and the hand-power size of handwheel.Simple structure, expense is cheap, is that railway uses in history the most remote, the brake that survivability is the most indomitable.The railway development initial stage, on rolling stock, only has this brake, per car or several car are equipped with a braking person, handle by driver's whistling command is collaborative, a little less than braking force, slow in one's movements, be not easy to driver's direct control, so replaced by impersonal force brake soon, hand brake becomes auxiliary brake for subsequent use.
utility model content:
the purpose of this utility model is to provide a kind of liquefied petroleum gas railway tanker brake equipment.
above-mentioned object realizes by following technical scheme:
a kind of liquefied petroleum gas railway tanker brake equipment, its composition comprises: brake pipe, described brake pipe is connected by angle cock with brake hose, described brake pipe is connected with cut out cock, described cut out cock is connected with dirt collector, described dirt collector is connected with GK type triple valve, described GK type triple valve is connected with brake cylinder, described brake cylinder is adjusted cock with empty and load and is connected, described empty and load is adjusted cock and is connected with safety valve, described safety valve is connected with step-down reservoir, and described brake cylinder is connected with auxiliary reservoir.
described liquefied petroleum gas railway tanker brake equipment, described safety valve is adjusted handgrip with bare weight and is connected.
beneficial effect:
when locomotive generation separation accident, when brake hose of the present utility model is pulled off, train pipe blast sharply declines, and triple-wave piston moves to retarder location automatically and promptly, therefore locomotive can be braked rapidly automatically until stop.This has not only improved locomotive operation safety, and to start time difference of brake action little in locomotive front and rear part, brake and alleviate-causing property is better, is applicable to the longer locomotive of marshalling.
the utility model can be adjusted brake-cylinder pressure with vehicle loading situation, and its method of adjustment is as follows: bare weight adjustment is to change the pressurized air volume that enters brake cylinder to realize.When empty wagons, brake cylinder and step-down reservoir are communicated with, in the time of braking, auxiliary reservoir pressurized air is except through triple valve enters brake cylinder, enter in step-down reservoir (volume is 17 liters), to reduce brake-cylinder pressure as empty parking space pressure, its brake-cylinder pressure is less simultaneously.When loaded vehicle, brake cylinder and step-down reservoir block, and in the time of braking, auxiliary reservoir pressurized air only, in triple valve enters brake cylinder, can not enter step-down reservoir, so brake-cylinder pressure is higher.During as service braking decompression 0.14MPa, brake-cylinder pressure can reach 0.36MPa, when emergency braking, can reach 0.38-0.4MPa, approximately doubles, thereby guaranteed the braking force that loaded position is higher compared with empty parking space brake-cylinder pressure.Brake cylinder and step-down reservoir to be communicated with blocking be to adjust cock by empty and load to control, empty wagons is adjusted to handgrip and beats when the empty wagon position, cock is just open-minded, handgrip is beaten in the time of loaded vehicle position, cock is just closed.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
the specific embodiment:
embodiment 1:
a kind of liquefied petroleum gas railway tanker brake equipment, its composition comprises: brake pipe 1, described brake pipe is connected by angle cock 4 with brake hose 5, described brake pipe is connected with cut out cock 2, described cut out cock is connected with dirt collector 3, described dirt collector is connected with GK type triple valve 10, described GK type triple valve is connected with brake cylinder 6, described brake cylinder is adjusted cock 9 with empty and load and is connected, described empty and load is adjusted cock and is connected with safety valve 8, described safety valve is connected with step-down reservoir 7, and described brake cylinder is connected with auxiliary reservoir 12.
embodiment 2:
according to the liquefied petroleum gas railway tanker brake equipment described in embodiment 1, described safety valve is adjusted handgrip 11 with bare weight and is connected.
