Description
Technical field
The utility model is related to locomotive technology field, specifically a kind of braking ability test device.
Background technology
Rail truck is divided into lorry and the major class of car two by purposes.Lorry is divided into common vehicle and metallurgy by smelter again
The class of vehicle two.Common vehicle multipotency described in smelter loads various goods not much in demands things, and versatility is stronger；Metallurgical vehicle metallurgy vehicle is that shipment is vehement
The special-purpose vehicle of goods in great demand thing, specificity is extremely strong.
It is most of that common vehicle structure composition is divided into four：Body portions, EEF bogie, hook delay portion, braking parts.To make vehicle frequent
Keep good state of the art and be provided with car inspection and repair system with performance, wherein performance detection need to lead to after the maintenance of vehicle braking parts
Overtesting equipment (single car testing device) simulation uses to complete.
To release the bottleneck of restriction car inspection and repair, the braking ability of maintenance outbound vehicle is ensured, in existing necessary resources bar
It is necessary effective measures that a kind of actual common vehicle braking ability test device of current maintenance that meets is developed under part.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of braking ability test device, specific skill
Art scheme is as follows：
A kind of common vehicle braking ability test device, including blast pipe, dust arrester, control valve, air relay valve, block
Cock, pressure gauge one and pressure gauge two；The blast pipe is connected by dust arrester with the air inlet of control valve, controls the air-out of valve
Mouthful it is connected with the air inlet of air relay valve, the air outlet of air relay valve is connected with cutout cock, cutout cock and vehicle master
Pipe is connected；Pressure gauge one is set between the effect end of air relay valve and blast pipe；Vehicle is responsible for and sets pressure and between cutout cock
Table two；Control valve sets handle.
The utility model has the advantages that：Using diesel locomotive valve, assembled by reasonable disposition, bicycle braking can be met
The requirements of performance test are accurate to judge vehicle brake performance, it is ensured that outbound vehicle operation safety.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of joystick.
Specific embodiment
The utility model is illustrated below in conjunction with the accompanying drawings, and as shown in Figure 1 and Figure 2, the utility model includes blast pipe, collection
Dirt device 1, control valve 2, air relay valve 3, cutout cock 7, pressure gauge 1 and pressure gauge 26；The blast pipe passes through dust arrester
1 is connected with the air inlet 21 of control valve, controls the air outlet 22 of valve to be connected with the air inlet 31 of air relay valve, air relay valve
Air outlet 33 be connected with cutout cock 4, cutout cock 4 and vehicle supervisor be connected；The effect end 32 of air relay valve and air intake
Pressure gauge 1 is set between pipe；Vehicle is responsible for and pressure gauge 26 is set and between cutout cock 4；Control valve sets handle 7.
As shown in Fig. 2 the controllable intake of the folding angle of the handle.If being divided into maximum intake from zero intake
Dry gear, such as 1-6 grade.
Application method of the present utility model：
Bicycle braking ability test totally four contents：
Full car leak-test：
Control valve handle is removed to full charge position, treats the pointer of pressure gauge two up to 0.5mpa, closes cutout cock, pressurize 1 minute,
Sew no more than 0.01mpa (half-space).
Braking, release sensitivity experiment：
Braking：Control valve handle is removed to full charge position, treats the pointer of pressure gauge two up to 0.5mpa, manipulates control valve handle progressively
Decompression, observes the pointer of pressure gauge two, and decompression 0.04mpa (2 lattice) plays braking.
Pressurize：Cutout cock, pressurize 1 minute are closed, pressure declines no more than 0.05mpa (2 half-space), unnatural alleviation.
Alleviate：Control valve handle is alleviated to full charge position fine motion in 45 seconds.(practical operation is difficult to hold)
(3) stable experiment is braked：
Control valve handle is removed to full charge position, treats the pointer of pressure gauge two up to 0.5mpa, manipulates control valve handle decompression step by step,
The observation pointer of pressure gauge two, decompression 0.14mpa (7 lattice) does not play brake hard in braking procedure, close cutout cock pressurize, no
Natural remission must occur.
(4) emergency braking testses：
Control valve handle is removed to full charge position, treats the pointer of pressure gauge two up to 0.5mpa, manipulates control valve handle fast decompression,
The observation pointer fast decompression 0.14mpa (7 lattice) of pressure gauge two, plays brake hard, and control valve handle is removed to full charge position and alleviated.
