In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of new electric locomotive speed measuring device, which can
The speed of service of monitoring record locomotive, traffic direction and testing result are reliable in real time.
The utility model is achieved through the following technical solutions above-mentioned technical purpose：
Electric locomotive speed measuring device provided by the utility model, including the gear ring that tests the speed, sensor and controller, it is described to test the speed
Gear ring is worn on the wheel shaft for being fixed on train wheel, and there are two the sensors and two sensors are concyclic is arranged in the gear ring that tests the speed
Side, the inductive probe of the sensor just corresponding to gear ring setting, and the width between two sensor outermost ends is less than simultaneously
Space width and tooth width, the sensor are connect with controller, and the controller is connect with display screen and acoustic-optic alarm.
Preferably, the gear ring that tests the speed is fixed at by disc holder on the wheel shaft of train wheel, the disk branch
Frame is worn on the wheel shaft for being fixed on train wheel, and the speed measuring fluted disc is arranged on disc holder, the diameter of the speed measuring fluted disc
More than the diameter that the diameter of disc holder is less than train wheel.
Wherein, the disc holder is made of two semi-discs, and the gear ring that tests the speed is made of two semicircles gear ring that tests the speed；
The joint of the semi-disc is respectively arranged with fixed plate, and the fixed plate is vertical with semi-disc, and the fixed plate passes through bolt
Two are fixed together, and the semi-disc is fixed together to form a disc holder by fixed plate；The semicircle tests the speed gear ring
It is separately positioned on corresponding semi-disc and the two forms a complete gear ring that tests the speed.
Preferably, the sensor is fixed at the side for the gear ring that tests the speed, the sensing by sensor fixing bracket
The support bracket fastened other end of device is fixed on electric locomotive car body.
The advantageous effects of the utility model are:
（1）The utility model works as survey by installing the gear ring that tests the speed on electric locomotive wheel shaft in combination with high-precision sensor
When sensor is passed through at fast gear ring interval, sensor is also intermittent to send out the signal for detecting gear, and controller is by analyzing and sentencing
Break and the speed of service of electric locomotive, when the speed of service that detection obtains is more than the numerical value of setting, controller controls sound-light alarm
Device sends out alarm signal, reminds driver's slow down；
（2）Due to there are two sensor settings, and the width between two sensor outermost ends simultaneously less than space width and
Tooth width, therefore can judge the signal sequences of two sensors by combination, judges the traffic direction of locomotive, that is, move backward or
Forward direction is driven；
（3）Disc holder and the gear ring that tests the speed are disposed as the circular configuration being made of semicircular structure, when installation more
It is convenient and efficient, without removing wheel to disk can will be tested the speed on wheel shaft, it is thus only necessary to which 2 workers work 1 hour
It completes, installation maintenance is very convenient.
Electric locomotive speed measuring device provided by the utility model, asking for velocity measuring can not be carried out by solving conventional motors vehicle
Topic is taken turns to that can be mounted on speed measuring fluted disc on axis, installation maintenance is very without being transformed to locomotive without wheel is removed
It is convenient.
Description of the drawings
Fig. 1 is the overlooking structure diagram of the utility model；
Fig. 2 is the front view of speed measuring device in Fig. 1；
1 train wheel in figure, 2 test the speed gear ring, 3 bolts one, 4 wheel shafts, 5 disc holders, 6 sensors fix branch
Frame, 7 sensors, 8 bolts two, 9 fixed plates.
Specific implementation mode
It is right with reference to the accompanying drawings and detailed description in order to which the structure and principle that make the utility model are more clearly understood
The utility model is described in detail：
As shown in Figure 1, 2, a kind of electric locomotive speed measuring device, including the gear ring 2 that tests the speed, sensor 7 and controller, test the speed gear ring
2 wear on the wheel shaft 4 for being fixed on train wheel 1, and there are two sensors 7, and two sensors are concyclic is arranged in the gear ring 2 that tests the speed
