Abstract
The invention discloses diesel engine speed regulation protective devices when a kind of locomotive emergency braking; including driver controller and diesel engine speed regulation module SCM; it is accessed between driver controller and diesel engine speed regulation module SCM after the normally-closed contact K1 of intermediate relay ESCR is in parallel with the normally opened contact of main generator excitation contactor AFC, intermediate relay ESCR connects again with machine control switch S2 with main generator excitation contactor AFC parallel connections and is followed by the positive and negative anodes of power supply.By using this protective device, locomotive implements emergency braking, and after diesel engine Condition of Sudden Unloading, diesel engine speed can be down to running down rotating speed automatically.Can to avoid diesel engine of locomotive due to rotating speed is out of control driving, avoid the generation of accident of locomotive defect, improve the safety of locomotive operation.The oil consumption for reducing locomotive simultaneously, improves the economy of locomotive.
Description
Technical field
The present invention relates to diesel engine speed regulation technical fields when locomotive emergency braking, and in particular to when a kind of locomotive emergency braking
Diesel engine speed regulation protective device.
Background technology
CKD7B type locomotives use the CAT3516 type diesel oil of U.S.'s Caterpillar (Caterpillar) company production
Machine, rotating speed control is that the output signal of driver controller different stalls is converted to difference by diesel speed signaling module
Electric potential signal is sent into Diesel Engine Control resume module, then reaches change diesel engine by adjusting the fuel delivery of diesel injector
The purpose of rotating speed, rotation speed change when diesel engine works normally is from 600r/min to 1800r/min.
After diesel engine starting, when the reversing handle of driver controller sets " preceding to lead " or " then lead " position, rotation control handle,
Internal control potentiometer resistance changes as rotation position is different, and different potentials are converted to by diesel speed signaling module
Signal is sent into Diesel Engine Control resume module, and the fuel delivery of adjusted diesel injector changes the mesh of diesel engine speed to reach
's.Control handle is rotated from lowest order to highest order, and diesel engine speed should rise to 1800r/min from 600r/min.
Locomotive is in high speed, large load operation, if because of ground connection, overcurrent, water temperature is high or other reasons cause locomotive to be implemented
Emergency braking, after diesel engine Condition of Sudden Unloading, diesel engine speed remains in current rotating speed, cannot be down to running down rotating speed automatically, holds
Easily cause diesel engine speed out of control and driving, causes locomotive accident of locomotive defect.
Invention content
For the above-mentioned prior art the shortcomings that and deficiency, diesel engine speed regulation is protected when the present invention provides a kind of locomotive emergency braking
Protection unit, locomotive implements emergency braking, and after diesel engine Condition of Sudden Unloading, diesel engine speed can be down to running down rotating speed automatically.
Diesel engine speed regulation protective device when the technical solution adopted in the present invention is locomotive emergency braking, including driver's control
The normally-closed contact K1's and main generator excitation contactor AFC of device and diesel engine speed regulation module SCM, intermediate relay ESCR is normally opened
It is accessed between driver controller and diesel engine speed regulation module SCM after contact shunt, intermediate relay ESCR and main generator excitation
Contactor AFC parallel connections connect with machine control switch S2 be followed by the positive and negative anodes of power supply again.
" 2 " port of diesel engine speed regulation module SCM is connected with the normally-closed contact K1 of intermediate relay ESCR.
Potentiometer R is provided in the driver controller.
The beneficial effects of the invention are as follows：Locomotive implements emergency braking, and after diesel engine Condition of Sudden Unloading, diesel engine speed can be automatic
It is down to running down rotating speed.Can to avoid diesel engine of locomotive due to rotating speed is out of control driving, avoid the generation of accident of locomotive defect, improve
The safety of locomotive operation.The oil consumption for reducing locomotive simultaneously, improves the economy of locomotive.

Fig. 2 is prior art diesel engine speed given circuit schematic diagram.
Fig. 3 is locomotive control circuit schematic diagram of the present invention.
Fig. 4 is diesel engine speed given circuit schematic diagram of the present invention.
It is marked in figure：S2- machine controls switch, ESCR- intermediate relays, AFC- main generator excitation contactors, SCM- diesel oil
Machine speed adjusting module, R- potentiometers, the normally-closed contact of K1-ESCR, the normally opened contact of K2-AFC.
Specific implementation mode
Now 1 to attached drawing 4, the present invention is described further with reference to the accompanying drawings, in the electric wiring of CKD7B type locomotives,
The anode that machine control switch S2 connects power supply is followed by intermediate relay ESCR, that is, an intermediate relay ESCR is accessed locomotive control
In circuit processed, intermediate relay ESCR is connected after drawing with power cathode, as shown in figure 4, by the normally closed of intermediate relay ESCR
Diesel engine speed regulation module SCM is accessed after contact K1 is in parallel with the normally opened contact K2 of main generator excitation contactor AFC, locomotive is from bavin
" 2 " port input speed-regulating signal (0.5V-4.5V) of oil machine speed adjusting module SCM is converted to different potentials signal and is sent into diesel engine
Control module processing, the fuel delivery of adjusted diesel injector reach change diesel engine speed.In this way, implementing in locomotive tight
When anxious braking, main generator excitation contacts of contactor K2 is disconnected, locomotive unloading, meanwhile, diesel engine speed regulation module SCM is obtained accordingly
Voltage signal, diesel engine speed automatically returns to running down rotating speed (600r/min), avoids diesel engine of locomotive due to rotating speed is out of control
Driving.And in locomotive zero load, this intermediate relay ESCR must not be electric, and normally-closed contact K1 is closed always, makes locomotive bavin
Oil machine still there is speed-regulating function diesel engine speed to follow speed-regulating signal linear change.When input speed-regulating signal is 0 or hanging
When, diesel engine speed should return to running down rotating speed.The generation for avoiding accident of locomotive defect improves the safety of locomotive operation.And
In locomotive no-load test, makes diesel engine of locomotive that still there is speed-regulating function, meet demand of the locomotive during debugging.
