Description
Technical field
The utility model belongs to subway car loopback process control experimental technique field, and in particular to a kind of subway car is exempted from without fire
Locomotive loop back test device.
Background technology
, it is necessary to which the automobile-used return vehicle of subway debugged after finishing is sent into user scene after the debugging of subway car vehicle terminates.
Because subway car needs to use lorry pattern (blast is 5bar) and car pattern (blast is 6bar) in loopback way, therefore,
Need to test lorry pattern and car pattern inside.During experiment, subway car connects after extension the locomotive, it is necessary in use with return vehicle
Blast main provides loopback control cabinet of the blast to subway car needed for experiment, and loopback control cabinet is according to the blast of reception to subway car
Brakes send braking apply and release of brake signal, and then carry out loop back test.But the locomotive in field can only be provided
5bar blast carries out lorry model test, it is impossible to provides 6bar blast and carries out car model test.
Utility model content
Locomotive carries out that during loop back test lorry model test can only be carried out in use field in order to solve prior art presence,
The technical problem of car model test can not be carried out, the utility model provides a kind of subway car and exempts from locomotive loop back test dress without fire
Put.
The utility model technical solution adopted for solving the technical problem is as follows：
Subway car exempts from locomotive loop back test device without fire, it include a triple valve, total wind table, blast regulating valve, No. two
Triple valve, No. three triple valves and train table；3 mouthfuls of a number triple valve are connected with the blast main of return vehicle, 2 mouthfuls of a triple valve
Connected with total wind table, 1 mouthful of a triple valve is connected with the air inlet of blast regulating valve；The air outlet of blast regulating valve and No. two
1 mouthful of connection of triple valve, 3 mouthfuls of No. two triple valves are connected with the train pipe of return vehicle, 2 mouthfuls and No. three threeways of No. two triple valves
2 mouthfuls of connections of valve；1 mouthful of No. three triple valves is connected with train table, and 3 mouthfuls of No. three triple valves are entered with the loopback control cabinet of subway car
Air port is connected；Total wind table is used for the blast for showing return vehicle blast main, and train table is used for the blast for showing return vehicle train pipe, wind
Pressure regulating valve is used to provide blast required during experiment.
The beneficial effects of the utility model are：The device carries out the loop back test of subway car without using locomotive in field, and
The loop back test of lorry pattern and car pattern both of which can be realized；Apparatus structure is simple, easy to operate, it is adaptable to various
The loop back test of vehicle；The present apparatus uses blast regulating valve, and degree of regulation is high, can not only save debug time, improves debugging
Efficiency, also makes debugging process more stable, substantially increases the security of subway vehicle commander's time transportation, it is ensured that subway car
The quality of vehicle.Using this experimental rig, the subway car organized into groups for a row 6 can save debug time about 6 hours, one
4 row subway cars of moon debugging can save the time of at least 24 hours.
Brief description of the drawings
Fig. 1 is the operation principle schematic diagram that the utility model subway car exempts from locomotive loop back test device without fire.
Embodiment
The utility model is described in further details below in conjunction with the accompanying drawings.
As shown in figure 1, subway car of the present utility model exempts from locomotive loop back test device without fire includes triple valve, a total wind
Table, blast regulating valve (for example, the model LR-3/8-D-MIDI of FESTO plates pressure regulator valve), No. two triple valves, side rows cut
Disconnected cock, No. three triple valves and train table；3 mouthfuls of a number triple valve are connected with the blast main of return vehicle, the blast main of return vehicle
For experimental rig air feed, 2 mouthfuls of a triple valve are connected with total wind table, and total wind table is used for the blast for showing return vehicle blast main；
1 mouthful of a number triple valve is connected with the air inlet of blast regulating valve；1 mouthful of company of the air outlet of blast regulating valve and No. two triple valves
Logical, blast regulating valve is used to provide blast required during experiment, and the range of regulation of blast regulating valve is 0~10bar；No. two threeways
3 mouthfuls of valve are connected with the train pipe of return vehicle, and 2 mouthfuls of air inlets for arranging cutout cock with side of No. two triple valves are connected, and side row cut
The air outlet of disconnected cock is connected with 2 mouthfuls of No. three triple valves；1 mouthful of No. three triple valves is connected with train table, and train table is used to show
Show the blast of return vehicle train pipe, 3 mouthfuls of No. three triple valves connect with the loopback control cabinet air inlet of subway car.
When subway car of the present utility model is exempted from locomotive loop back test device without fire and used：Blast regulating valve is by the total wind of return vehicle
The blast that pipe is provided is adjusted to after 5bar or 6bar, arranges cutout cock by No. two triple valves, side and No. three triple valves give subway
The loopback control cabinet of car, the quick air draft of cutout cock progress can be arranged by side and realizes that low precision is depressurized, can also be led to during decompression
Cross blast regulating valve and realize high accuracy decompression.When carrying out lorry model test, it is pressurized by blast regulating valve to loopback control cabinet
To 5bar, subway car vehicle is in relieved state, and brake pressure is 0bar, the blast using blast regulating valve to loopback control cabinet
When being decompressed to 4bar, subway car vehicle applies braking, and brake pressure is in 0.12bar or so；Then blast regulating valve is reused
When filling wind to 5bar to loopback control cabinet, subway car vehicle release of brake.When carrying out mode of passenger transportation experiment, pass through blast regulating valve
6bar is pressurized to loopback control cabinet, subway car vehicle is in relieved state, the wind using blast regulating valve to loopback control cabinet
When pressure is decompressed to 5bar, subway car vehicle applies braking, then reuses blast regulating valve and fills wind to 6bar to loopback control cabinet
When, subway car vehicle release of brake.
