Two sets of valve devices (3) are connected with a total air cylinder; and the valve device is formed in such a way that a cut-off plug door (4), an air pressure reducing valve (5) and a check valve (6) are connected with a cut-off plug door (7) in parallel after being connected with each other in series. When a single machine is pulled to a bus, the cut-off plug door (7) is closed, a locomotive total air double heading channel is cut off, the cut-off plug door (4) is opened and a vehicle air supply channel is opened (the air pressure is 600 KPa); when the bus is pulled through freight double heading, the cut-off plug door (4) is closed, a channel for supplying air to a passenger train is cut off, the cut-off plug door (7) is opened and a locomotive total air double heading channel is opened (the air pressure is 900 KPa); and when the locomotive is pulled through double heading, the cut-off plug door (7) at the corresponding end of the leading locomotive is opened, the bus is pulled through leading locomotive double heading after the cut-off plug door (4) is cut off, the leading locomotive is positioned in a double heading position, the cut-off plug door (7) shall be closed at the corresponding end when the locomotive is connected with the bus, and an air source (the air pressure is 600 KPa) is provided to the bus after the cut-off plug door (4) is opened.
Description
Technical field
The present invention relates to the railway locomotive technology, relate in particular to a kind of both ends of locomotive and operate two-tube air supply method.
Background technology
In recent years, quasi high-speed vehicle has generally adopted devices such as traveling portion air bellow, pneumatic car door, defecate collection device, has increased the auxiliary air quantity of using greatly.In order to replenish the auxiliary wind of using on the vehicle fast, need on the locomotive of traction passenger train, install two-tube air supply device additional.So-called two-tube air feed is meant carries out two-tube air feed to passenger vehicle, and one is traditional train brake pipe (500kPa or 600kPa), and another is that the independent air feed pipe of vehicle (600kPa) is referring to accompanying drawing 1.When locomotive double heading, dwell period plug door C01 opens stage plug door C04, and the train locomotive first reservoir A02 pressurized air gets into locomotive blast main road through stage plug door C04, and total wind pressure of 750~900KPa is provided to assisting vehicle through end total wind flexible pipe C06.This moment, total wind table D03 showed the first reservoir pressure, also can observe compressor start-stop pressure through this wind table.And when the two-tube air feed of passenger train; Dwell period plug door C04 then; Open stage plug door C01, the train locomotive first reservoir A02 pressurized air is through stage plug door C01, reducing valve C02; Boiler check valve C03 gets into locomotive blast main road, and total wind pressure of 600kPa is provided to passenger train through end total wind flexible pipe C06.This moment, total wind table D03 showed passenger vehicle air feed pressure, can observe compressor start-stop pressure through locomotive brake gear B01.
Because a shared total wind pressure table, in the working direction driver's cab, bus attendant can't be observed total wind pressure value of this car and the force value of independent air feed pipe is provided for vehicle through compression indicator simultaneously.After locomotive double heading operation, can't guarantee the total wind pressure value (900kPa) between locomotive simultaneously and independent air feed pipe pressure value (600kPa) is provided for vehicle.Particularly behind the locomotive et out of order, even there is blast main the breakdown locomotive end, total also can't guarantee fault locomotive wind pressure value (900kPa) simultaneously and independent air feed pipe pressure value (600kPa) is provided for vehicle.
Summary of the invention
The object of the invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of both ends of locomotive to operate two-tube air supply method, this method can:
Be that vehicle provides independent air feed pipe pressure value (600kPa) when 1, satisfying single-unit locomotive traction passenger vehicle;
2, during the locomotive traction passenger vehicle, in the driver's cab of working direction, can observe total wind pressure value of this car easily and the force value of independent air feed pipe is provided for vehicle.
When 3, locomotive double heading is operated, both can guarantee the total wind pressure value (900kPa) between locomotive, can guarantee again provides independent air feed pipe pressure value (600kPa) for vehicle.
When 4, locomotive failure need not have fiery loopback; As long as there is blast main the breakdown locomotive end, just can guarantee the puzzled volume of train, directly draw by breakdown locomotive; Guarantee the fault total wind pressure value of locomotive (900kPa), can guarantee to continue to provide independent air feed pipe pressure value (600kPa) simultaneously for vehicle.
The objective of the invention is existing like this: a kind of both ends of locomotive is operated two-tube air supply method, it is characterized in that:
A) two covers are connected to total reservoir by cut out cock (4), air pressure reducing valve (5), boiler check valve (6) series connection back with the valve gear (3) of the parallelly connected formation of cut out cock (7);
B) when the single engine passenger vehicle, need, vehicle close cut out cock (7) when providing wind regime, cut off the heavy UNICOM of the total wind of locomotive road, open cut out cock (4), open to vehicle intake adit (blast 600kPa);
C) when shipping heavily joins traction, close cut out cock (4), cut off passage, open cut out cock (7), heavy UNICOM road (blast 900kPa) of the total wind of open locomotive to the passenger train air feed;
D) when passenger traffic heavily joins traction; Open train locomotive corresponding end cut out cock (7); Close cut out cock (4) back and heavily join traction by train locomotive; This locomotive is in double-heading position, and this locomotive connects corresponding end with passenger vehicle should close cut out cock (7), can wind regime (blast 600kPa) be provided to passenger vehicle after opening cut out cock (4);
When e) the fault locomotive need be rescued, if there is total wind flexible pipe the breakdown locomotive end, fault locomotive operation mode was with d) the bar content.
Scheme of the present invention; For satisfying the various operating modes of on-the-spot utilization; On blast main road, locomotive front and back end, respectively use a cover reducing valve; Through pressure sensor, the driver's cab Real Time Observation locomotive other end (with the passenger vehicle coupling end) total wind pressure state that supplies in the operating side is observed the total wind pressure value of this joint locomotive through draught indicator; Can realize that through the cut out cock conversion single-unit locomotive traction passenger vehicle provides independent air feed pipe pressure value (600kPa), both guarantee the total wind pressure value of locomotive (900kPa) in the time of also can realizing locomotive double heading, can be passenger vehicle again independent air feed pipe pressure value (600kPa) is provided; After simultaneously also can realizing locomotive failure,, need not separate and compile direct tractor-trailer train, continue as passenger vehicle independent air feed pipe pressure value (600kPa) is provided through the total wind of breakdown locomotive.
