Description
Technical field
The present invention relates to diesel locomotive electronic control technology, particularly relate to a kind of diesel locomotive stucco electric control gear.
Background technology
For giving full play to locomotive adhesion tractive force, prevent wheel spin and slide, DF7 series internal combustion locomotive
It is provided with sander；Sander is made up of electromagnetic valve, sand sprayer and pipeline.Driver passes through foot switch
Control stucco, or when locomotive control microcomputer detects wheel pair idling, automatic stucco.
The principle of existing automatically controlled sander is as it is shown in figure 1, stucco control process is as follows:
1) manually control circuit controls stucco, equipped with left food switch 1 He on bench board driver's pedal
Right threading switch 2, during one of them switch Guan Bi, has one to obtain in forward electromagnetic valve and reverse electromagnetic valve
Electronic work, the pressure air come from total reservoir enters sand sprayer, by sand pipe, sand blasting is spread to rail level
On, forward electromagnetic valve and reverse electromagnetic valve include normal open switch 5 and normally closed by a pair locomotive reverser
Switch 6 controls respectively, only makes locomotive forward direction stucco；Main switch 7 is used for safeguarding or keep in repair automatically controlled
Loop is used；During online use, due to supply voltage height, the first diode 8 is used for controlling electric current
One direction passes through forward electromagnetic valve coil 3, and the second diode 9 is used for controlling electric current one direction by reversely
Electromagnetic valve coil 4, the 3rd diode 10 is used for controlling electric current one direction and passes through major loop；
2) controlling automatic stucco by pressure switch, when brake hard, pressure switch airduct fills wind,
Pressure switch 11 action, connects circuit, forward electromagnetic valve or reverse electromagnetic valve energized action, total reservoir
Pressure air enter sand sprayer stucco.
3) automatic stucco is controlled, when traction motor maximum current by microcomputer control signal circuit 12
> 500A, maximum current difference and the ratio of average current > 20% time, microcomputer control stucco display simultaneously therefore
Barrier Information shows " idle running " if can eliminate idle running by stucco, and difference between current diminishes, then be automatically stopped
Stucco.If idle running increases further, when ratio > 30% time, microcomputer controls to continue stucco linear reduction
Main generator output, display simultaneously " seriously idle running ".After idle running eliminates, microcomputer is automatically stopped and spreads
Sand, and recover the original power of main generator.
Prior art has the disadvantage in that
1, the still frequently stucco when locomotive does not has speed, not only causes the wasting of resources and environmental pollution, and
And composition potential safety hazard.The sand pad that during unit brake hard, self stucco causes may block track circuit；
The sand pad that multiple locomotives cause in same local stucco for a long time equally makes to rest on the machine on sand pad later
The track circuit of car is not turned on, composition accident crisis.
2, only having foot switch, driver can only operate with foot, once malfunctioning switch, it is impossible to operation.
3, during train starting traction, without automatic stucco, and after disappearance of dallying, no-delay stucco function.
Locomotive cannot be given full play to and start adhesion tractive force.
4, in section, during servicing work, the emergency braking tests of locomotive brake gear is necessary pilot project, this test
Cause unnecessary stucco.
Summary of the invention
The present invention provides a kind of diesel locomotive stucco electric control gear, is used for overcoming defect of the prior art,
Realize saving sand grains, reduce waste and environmental pollution；Increase locomotive adhesion；Strengthen traffic safety.
The present invention provides a kind of diesel locomotive stucco electric control gear, and this device includes for according to train pipe pressure
Power and preset value comparative result and close pressure switch, forward stucco electromagnetic valve, reverse stucco electromagnetism
Valve and control circuit, this control circuit includes two parallel connections being connected between DC power anode and negative pole
Branch road, one of them parallel branch includes this pressure switch；Another parallel branch includes the manual of series connection
Control circuit, stucco circuit and main switch, this device also includes the velocity pick-up for detecting vehicle wheel rotational speed
Device, the vehicle wheel rotational speed detected according to this velocity sensor and preset rotation speed comparative result and a pair of action
Contact and time-delay relay, this includes normally opened contact and normally-closed contact, described time-delay relay bag to contact
Include time delay coil and time delay normally-closed contact, described time delay coil and normally opened contact all with described pressure switch
Series connection, the circuit on one side after described normally-closed contact is in parallel with described time delay normally-closed contact be connected to described manually
Between control circuit and stucco circuit, the other end be connected between described pressure switch and time delay coil or
It is connected between pressure switch and normally opened contact.
The diesel locomotive stucco electric control gear of the present invention, when emergency braking condition, train tube pressure becomes big,
Pressure switch closes, and electromagnetic valve obtains electric, starts stucco, and velocity sensor detects that the rotating speed of wheel is low
When preset value, normally opened contact closes, and normally-closed contact disconnects, and time delay coil obtains electric, time delay normally-closed contact
Disconnect after the time set, control stucco amount by time-delay relay, when locomotive does not has speed
Will not stucco, hinge structure economizes on resources, protects environment, it is to avoid potential safety hazard；Unit is promptly made
The sand pad that time dynamic, self stucco does not results in blocks track circuit；Multiple locomotives are for a long time in same local stucco
Also not resulting in sand pad the most also will not make the track circuit resting on the locomotive on sand pad later be not turned on,
Avoid composition accident crisis.
