Described pair of air bag bow-lifting device 10 mainly comprises connecting panel 26, steel rope assembling 23, rises bow air bag 28, adjusts plate 29, butterfly seat 30.Connecting panel 26 1 ends and underframe 2 are hinged, and an other end is fixed on the butterfly seat 30.Steel rope is assembled 23 1 ends and is fixed on the butterfly seat 30, and the other end is fixed on the lower arm rod 3.Butterfly seat lower end with rise bow air bag 28 on is connected, left end is connected with connecting panel 26, liter bends air bag 28 lower ends and is connected with underframe 2.Adjusting plate is fixed on the lower arm rod 3.When gas circuit is assembled to liter bow air bag 28 air feed, rise bow air bag 28 expansion lifting butterfly seats 30, driving connecting panel 26 rotates with respect to underframe 2, rise bow air bag 28 lifting power simultaneously and pass to lower arm rod 3 through adjusting plate by steel rope assembling 23, pulling lower arm rod 3 makes it rotate with respect to underframe 2, thereby realize the liter bow operation of whole pantograph, otherwise then fall bow by deadweight.Rise bow air bag 28 in the described pair of air bag bow-lifting device 10 and make, can bear-40 ℃～+ 70 ℃ ambient temperatures, long service life for special rubber materials.
Described air valve case apparatus 14 mainly comprises air valve casing 31, air filtration valve 32, rises bow pressure regulating valve 33, accurate voltage regulating valve 34, safety valve 35, falls bow pressure regulating valve 36 etc.Air valve case one end interface is connected with air-path interface 18 with shutoff valve 13 by gas circuit, and the pipeline that enters in the air valve case is divided into two by T-pipe joint, is connected by two ends air-path interface, gas circuit and joint and pair air bag bow-lifting devices 10 (two independently air bag).The air valve case is integrated air filtration valve 32, rise bow pressure regulating valve 33, accurate voltage regulating valve 34, safety valve 35, fall gas circuit element such as bow pressure regulating valve 36.When locomotive compressed and supplied air process air filtration valve 32, filter disc rotates under gas pressure, because the influence of centnifugal force, airborne moisture, impurity are thrown to the valve wall and flow down along the valve wall, realize the filtration of air.Enter after through the pressurized air of filtering and to rise bow pressure regulating valve 33 by two-way joint, when pressure gas flows from right to left, when promptly the gas circuit flow direction is bent for falling, realization free flow that liter bends in the middle of the pressure regulating valve 33 and the avris path all can flow, can not influence and fall the bow airshed, not fall the bow time thereby do not influence.When pressurized air flowed from left to right, promptly gas circuit flowed to when rising arciform attitude, and avris stops up, and by the circulation of the gap to the filter core limit, realizes throttling by the spinning in and out may command flow of knob, thereby realizes rising the adjustment of bow time.Enter described accurate voltage regulating valve 34 through the pressurized air that rises bow pressure regulating valve 33 by two-way joint, set an occurrence by the knob compression spring in advance, when air pressure during greater than setting value, diaphragm is by jack-up, and middle aperture is disappointing, by normal drain port exhaust to atmosphere; When air pressure during smaller or equal to setting value, aperture is by the piston dieback in the middle of the diaphragm, and pressurized air does not leak.One barometric mounting interface is arranged on the accurate voltage regulating valve 34, when the needs reading, but an air-pressure gauge reading is installed, adjust air pressure after, pull down air-pressure gauge and tighten this interface with socket bolt.Pressurized air through accurate voltage regulating valve 34 enters described safety valve 35 by joint and pipeline, gas circuit dispense font etc., when air pressure just often, seal ring and disappointing port closed contact; When air pressure was the setting value of safety valve 35 greater than spring pressure, seal ring was by jack-up, and gas circuit is led to atmosphere, thereby realized overvoltage protection.The pressurized air of process safety valve 35 place gas circuit dispense font enters by two-way joint falls bow pressure regulating valve 36, the structure, material, size and the described liter bow pressure regulating valve 33 that fall bow pressure regulating valve 36 are in full accord, just the installation site is just in time opposite, this moment is if when rising the air-flow of bow direction, two gas circuits are all crossed air-flow, do not influence a liter bow airshed size, promptly do not influence and rise the bow time, when falling the bow air-flow, the gas circuit of having only avris can reconcile flow is crossed air-flow, thereby realizes falling the adjustment of bow time by the adjusting of falling the bow airshed.Transfer the pressurized air of press-flowing valve 36 to enter in the liter bow air bag of pantograph through falling bow, thereby realize rising the bow operation through joint and pipeline.
Described gas channel of pantograph comprises air-path interface 18, stop valve 13, connect shutoff valve 13 to the pipeline of air valve case 14 and joint, be connected air valve case 14 to pair rising the pipeline that bends airbag apparatus 10 and joint etc.Its air flow line is connected on the air valve case 14 by the single gas circuit of air-path interface 18, stop valve 13, and behind air valve case 14, gas circuit is divided into two and is connected on two airbag apparatus 10.When pantograph carries out safeguarding on the car, rise bow for fear of accident, can close stop valve 13, this moment, whole gas circuit was cut off, and also can not rise bow even pressed liter bow button in the car, thereby protect roof service personnel safety.
Described system damping device part 11 1 ends are connected on the underframe 2, and an end is connected the lower end of lower arm rod 3.When pantograph rises bow, system damping device 11 is compressed, damping this moment is very little, can ignore, when bow fell in pantograph, system damping device 11 was stretched, this moment, the damping of pantograph damper was worked, damping increases gradually, soon is in pantograph and falls bow damping maximum during the position, reduces again afterwards.Show as first quick and back slow when therefore bow falls in pantograph, thereby avoided fast prompt drop bow that roof is impacted.
The described bow notch indicator part 12 of falling is made up of activation members, support, insulator, slip ring, spring, position switch etc.Fall bow during the position when pantograph is in, depress activation members, bow indicating circuit closure falls in the position switch closure, and falling the bow indicator lamp in the vehicle will light, and shows that pantograph is in to fall arciform attitude.
Accompanying drawing 4 is schematic diagram of gas circuit of the present utility model, its principle of work is: when automatically controlled blow off valve gets when electric, pressurized air is passed through flexible insulated hose, gas channel of pantograph enters air valve case 14, air filtration valve 32 by the air valve case apparatus, rise bow pressure regulating valve 33, accurate voltage regulating valve 34, safety valve 35, fall gas circuit elements such as bending pressure regulating valve 36 and enter other one section gas channel of pantograph once more, pressure gas enters two bow airbag apparatus 23 that rise afterwards, rise bow air bag 28 expansion lifting butterfly seats 30, driving connecting panel 26 rotates with respect to underframe 2, rise bow air bag 28 lifting power simultaneously and pass to lower arm rod 3 through adjusting plate by steel rope assembling 23, pull lower arm rod 3 it is rotated with respect to underframe 2, thereby the liter bow of realizing whole pantograph is operated.When automatically controlled blow off valve dead electricity, the supply of automatically controlled exhaust valve closure pressure gas, the whole gas circuit of pantograph is led to atmosphere, and pantograph realized falling bow by deadweight and operated this moment.
