Description
Technical field
This utility model belongs to low floor vehicle technical field of auxiliary equipment, especially relates to spreading of a kind of automatic adjustment sand amount
Sand system.
Background technology
Under the conditions of sleety weather and specific road conditions, low floor vehicle generally requires sander in enforcement to be carried out track
Stucco, to improve the adhesion strength between wheel track, auxiliary realizes the operations such as deceleration or brake.At present in China's low-floor industry
In, major part sander blast amount can not be automatically adjusted, and some can realize the system of sand amount regulation, past
Toward the mode using machinery to adjust, as changed to the latus rectum of air quantity to reach the blast gas in blast interruption-forming different in flow rate,
And then control the supply of different sand amount.This type of sander is complex in the control of stucco source of the gas, need to by choke valve,
Its shortcoming is that regulation process is the most accurate.
Utility model content
The purpose of this utility model is to overcome prior art not enough, it is provided that the stucco system of a kind of automatic adjustment sand amount,
With current mechanical type adjusting apparatus ratio, can be more convenient, carry out the adjustment of sand amount more quantitatively, the regulation of sand amount is more accurate,
In hgher efficiency.
The technical solution of the utility model is: the stucco system of a kind of automatic adjustment sand amount, including sandbox, under described sandbox
End connection has sanding machine, and described sanding machine is connected by sand pipe nozzle, and described sandbox is connected by air main pneumatics
System, is provided with master on described air main and blows electromagnetic valve and electric Proportion valve.
Further, described sandbox is also associated with rear airduct, and described sandbox is connected with air compression system, described by rear airduct
After-blow electromagnetic valve is installed on rear airduct.
Further, in described sandbox, sand level sensor it is provided with.
Further, in described sandbox, it is provided with heater.
Further, described electric Proportion valve includes manual trigger mechanism and automatic trigger mechanism, described manual trigger mechanism by
Driver manually triggers, and described automatic trigger mechanism is triggered by trailer system and brakes.
This utility model has the advantage that with good effect: owing to using technique scheme, this utility model user
Just, it is easy to control, be favorably improved the adhesion coefficient between low floor vehicle wheel and rail, improve vehicle pull strength,
Brake force, prevents wheel-slip, improves vehicle safety in operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, sandbox 2, sanding machine 3, sand pipe
4, nozzle 5, air main 6, air compression system

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
Shown in structural representation as of the present utility model in Fig. 1, this utility model provides the stucco system of a kind of automatic adjustment sand amount
System, including sandbox 1, described sandbox 1 lower end connects sanding machine 2, and described sanding machine 2 is connected by sand pipe 3 spray
Mouth 4, described sandbox 1 is connected by air main 5 air compression system 6, is provided with master and blows electromagnetic valve on described air main 5
7 and electric Proportion valve 8.
Described sandbox 1 is also associated with rear airduct 9, and described sandbox 1 is connected with air compression system 6, described by rear airduct 9
On rear airduct 9, after-blow electromagnetic valve 10 is installed.It is provided with sand level sensor 11 in described sandbox 1.At described sandbox 1
Inside it is provided with heater 12.
Described electric Proportion valve 8 includes manual trigger mechanism and automatic trigger mechanism, and described manual trigger mechanism is by driver's hands
Dynamic triggering, described automatic trigger mechanism is triggered by trailer system and brakes.
The work process of this example: the stucco system of the sand amount that automatically adjusts that this utility model provides, blows electricity by controlling master
Magnet valve 7 controls stucco, opens gas circuit when master blows electromagnetic valve 7, flows through the wind of air main 5 successively by air compression system 6
Through sand sprayer 2, sand pipe 3, nozzle 4, sand is scattered between wheel and rail；Hold one's breath in main electromagnetic valve 7 pass of blowing
Road then stops stucco.During carrying out stucco, by using electric Proportion valve 8 to carry out the adjustment of blast tolerance, electrically
Proportioning valve 8 includes manual trigger mechanism and automatic trigger mechanism, and manual trigger mechanism is controlled by potentiometer circuit,
Automatically trigger mechanism can be controlled by the speed of service of rail vehicle, the actual condition that user runs according to vehicle, gas
Wait change etc., the size of the control signal of sets itself sand amount, thus realize being automatically adjusted of sand amount quickly, contribute to
The adhesion coefficient improving between railway vehicle wheel and rail with more ' quantifying ', prevents wheel-slip, improves vehicle and runs peace
Quan Xing.
The input signal of electric Proportion valve 8 is voltage signal, is output as linear corresponding relation, at this patent with controlling pressure
In, use input 4-20mAVDC correspondence to be output as the high precision electric proportioning valve 8 of 0-0.5Bar, as default air channel exports
When force value is 0.25bar, given current signal is the 12mA. mathematical relationship according to air channel output pressure Yu air-flow, user
Just can realize the flow-control to blast air-flow by setting the pressure of ducting outlet, blast flow control accuracy is more accurate,
More stable.
Use heating technique in this application, by heater 12, the sand in sandbox 1 is periodically heated, make sand ball
Without caking phenomenon when urgent, and it is additionally provided with sand level sensor 11 at sandbox 1, can be certainly by sand level sensor 11
Sand amount in dynamic detection sandbox 1, saves artificial.
Above an embodiment of the present utility model has been described in detail, but described content be only of the present utility model relatively
Good embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
