Abstract
The invention a rotating speed detection and simulation device of a diesel locomotive traction motor, and relates to a device for simulating the rotating speed of a traction motor. The device mainly solves the problems that the damage ratio of a sensor for measuring the rotating speed of a traction motor on a diesel locomotive is high, after the sensor is damaged, a replaced sensor needs to start a diesel engine, and verify whether the sensor is normally operated at the dynamic state of a moving locomotive, and time, manpower and fuel consumption are wasted. The device adopts the structure that a simulation and speed measurement transmission rod is connected with a base through a bearing; a rotating disc is fixed at one end of the simulation and speed measurement transmission rod; a simulation and speed measurement gear is fixed at the other end of the simulation and speed measurement transmission rod; a sliding block is arranged on the side surface of the periphery of the simulation and speed measurement gear; the sliding block is fixed on a sliding rod on the base through a locking screw. When the device rotates for a circle, the simulation and speed measurement gear sends 68 pulse signals to the sensor. The sensor inputs the signals to a microcomputer system on the locomotive, and the microcomputer system works out the rotating speed of the traction motor. The device has a simple structure, is convenient to operate, reduces the labor intensity, and improves the operating efficiency.
Description
Technical field
The present invention relates to the traction electric machine Rotating speed measring analogue means on a kind of locomotive, specifically relate to locomotive after traction electric machine speed probe is changed, simulation locomotive mule carriage process, to sensor generation signal, checks a kind of traction electric machine Rotating speed measring analogue means whether this speed probe is working properly.
Background technology
DF8B locomotive has 6 traction electric machines, and each traction electric machine has a sensor measuring its rotating speed, is called traction electric machine speed probe (hereinafter referred to as sensor).Because this sensor degradation rate of a variety of causes is higher, when changing after sensor degradation, this traction electric machine rotating speed can be seen in locomotive display screen.More emat sensor is pretty troublesome, plugs sensor plug, installs sensing head, adjustment sensing head gap etc.After replacing sensor, will verify that whether this sensor is working properly in dynamic state.First check that sensor strictly installs by technique, then starts diesel engine, then locomotive is walked, so just can judge that whether this sensor is normal.Abnormally if worked will to change, again to test.Such process is not only lost time but also take manpower and oil consumption.
Summary of the invention
Object of the present invention is exactly provide a kind of structure simple, easy to operate for above-mentioned weak point, can reduce labor intensity, save oil consumption and time, the diesel locomotive traction electric machine Rotating speed measring analogue means can increased work efficiency again.
Technical solution of the present invention is: diesel locomotive traction electric machine Rotating speed measring analogue means, it is characterized in that: simulate the drive link that tests the speed and be connected on base by bearing, the one end of simulating the drive link that tests the speed is fixed with rotary disk, the other end is fixed with simulation and surveys number gear, the side surveying number circumference of gear in simulation is provided with slide block, and slide block is fixed on the slide bar on base by lock-screw.
It is identical with the simulation survey number gear on locomotive that number gear 10 is surveyed in simulation described in technical solution of the present invention, and existing 68 teeth, send 68 pulses when diesel locomotive traction electric machine Rotating speed measring analogue means rotates a circle to sensor.
Slider bottom described in technical solution of the present invention is fixed with two nuts, and slide block is connected on the slide bar on base by the lock-screw on nut; The upper end of described slide block is provided with the draw-in groove seat of fixation of sensor.
The present invention, by the application of motor speed test simulator, solves and judges that process is complicated, the processing procedure of motor-car checking back and forth in the past, in real work, obtain good result.It is simple that this analogue means has structure, easy to operate, both reduced labor intensity, and be beneficial to again employee's operation, and can increase work efficiency, again can the advantage that repairs of lean.

Embodiment
As shown in Figure 1, 2, 3, simulating the drive link 6 that tests the speed is connected on base 1 by two bearings 4,7, two bearings 4,7 are arranged in nut 5,8 respectively, nut 5,8 is fixed by welding on base 1, simulation test the speed drive link 6 one end on be fixed with rotary disk 3, rotary disk 3 is welded on simulation and tests the speed on drive link 6, rotary disk 3 is fixed with handle 2, and handle 2 is axially fixed in rotary disk 3 circumferentially along rotary disk 3, the other end of simulating the drive link 6 that tests the speed is fixed with simulation and surveys number gear 10, the number of teeth that number gear 10 is surveyed in simulation is identical with the simulation gear on diesel locomotive, namely there are 68 teeth, send 68 pulses when diesel locomotive traction electric machine Rotating speed measring analogue means rotates a circle to sensor, the side surveying number gear 10 circumference in simulation is provided with a slide block 9, the bottom of slide block 9 is fixed with two nuts 12, base 1 is fixed with two slide bars be parallel to each other 13, on base-mounted two slide bars 13 of two nuts 12 bottom slide block 9, nut 12 is provided with lock-screw 11, slide block 9 to be fixed on the slide bar 13 on base 1 with lock-screw 11 by the nut 12 of bottom, unclamping lock-screw 11 can make slide block 9 move on slide bar 13, the distance of number gear 10 circumference is surveyed for adjusting slider 9 and simulation, the upper end of slide block 9 is provided with a U-shaped draw-in groove seat, for fixation of sensor.
Principle of work: be contained in by sensor head on the draw-in groove seat of slide block 9, regulates sensor head end face to survey number gear 10 gap with simulation by moving slider 9 on slide bar 13 and is 1mm ~ 1.2mm, is locked by slide block 9 with lock-screw 11.Plug sensor plug, now the microcomputer of sensor just and on locomotive links together, and sensor has just had detection power supply
,at this moment start that diesel engine makes that rotating speed reaches 1000rpm and locomotive is not walked, handle 2 on shake rotary disk 3, simulation is surveyed number gear 10 and is rotated with the simulation drive link 6 that tests the speed, due to magneto-electric induction principle, send 68 pulse signals by simulating survey number gear 10 to sensor when traction electric machine Rotating speed measring analogue means rotates a circle.By sensor, these signals are inputted microsystem on locomotive, calculated the rotating speed of traction electric machine by microsystem.If the display screen on locomotive has rotating speed to show, illustrate that this speed probe is working properly, otherwise must replacing one try again.
