There are two types of for motor vehicle Derail detectors of current track, and one kind being mounted in frame end, is located at wheel to advance
Direction is integrated with barrier detecting apparatus, and sensor is contacted with rail when principle is train derailing, issues alarm signal
Number.This Derail detector has one disadvantage in that, due to being mounted on frame end and device itself heavier-weight, therefore examines to derailing
The intensity requirement for surveying device mounting bracket is higher, and design risk is big, seriously affects the reliability of Derail detector, or even turn to
Frame reliability of structure itself.One kind is mounted on axle box or framework, judges to turn using monitoring acceleration vibration amplitude
Whether derail to frame and vehicle, is chiefly used in truck vehicle.Since acceleration vibration amplitude interference effect is more, high rate of false alarm is brought
Risk.In addition when vehicle derailing, the Derail detector of both types cannot be protected bogie part.
In conclusion how to provide, a kind of detection is reliable, the derailing of protection bogie part can detect in derailing
Device is a problem to be solved by those skilled in the art.
Utility model content
Technical problem to be solved in the utility model is, the shortcomings that in view of existing Derail detector, provides a kind of rail
Whether road vehicle Derail detector occurs derailing behavior with real-time detection bogie, and can play protection in derailing and turn
Effect to frame components.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of derailing detection used for rail vehicle
Device, including across the transition crossbeam for being mounted on bogie frame bottom, the transition crossbeam is mounted in the middle part of bogie frame,
And it is located at the lower section of traction electric machine；On the transition crossbeam with wheel corresponding position pressure sensor, the pressure of the pressure sensor
Power detection unit is stretched out by transition crossbeam bottom, and the signal processing unit output cable of the pressure sensor is connected to Train Control
System.
Above scheme further improvement is that sensor mount, position is arranged with wheel corresponding position on the transition crossbeam
It is longitudinal from top to bottom through the detection hole of transition crossbeam in being arranged on the transition crossbeam of sensor mount bottom；The sensor
The setting pressure sensor in mounting portion, the bullet that the interior setting of the detection hole is connect with the pressure sensing cell of pressure sensor
Property component.The elastomeric element is preferably spring, and the top of the spring connects pressure sensor, and bottom is arranged a spring and installs
Plate.
Above scheme further improvement is that the sensing is respectively set with two sides wheel corresponding position on the transition crossbeam
Device mounting portion, and the pressure sensor, spring and spring mounting plate are set.
Above scheme further improvement is that the transition crossbeam is arranged on bogie frame through mounting base.
Above scheme further improvement is, the transition crossbeam be include the i shaped steel structure of upper beam and underbeam, and institute
It states sensor mount and detection hole is arranged on underbeam.
Above scheme further improvement is that the output cable is connected with train monitoring center, further increases train row
Sail safety.
The utility model is set on transition crossbeam with wheel corresponding position by installing transition crossbeam in the middle part of bogie frame
Pressure sensor and detection spring are set, and the output signal of pressure sensor is connected to train control system, so as to pass through pressure
Whether sensor real-time detection bogie and vehicle occur derailing behavior: if vehicle operates normally, pressure sensor is experienced not
To spring pressure, normal operation signal is issued；When vehicle derailing, spring and transition crossbeam are contacted with rail, and spring is pressurized simultaneously
Pressure is transferred to pressure sensor, pressure sensor issues alarm signal.
The utility model is not only simple in structure, and whether energy real-time detection bogie occurs derailing behavior, due to transition crossbeam
Immediately below traction electric machine, and across left and right rail, in derailing, transition crossbeam is contacted with rail first, can protect traction
Motor is not damaged, substantially increases the travel safety of train.
Detailed description of the invention
Fig. 1 looks up status diagram for the utility model Derail detector mounting structure.
Fig. 2 is the main view status diagram of the utility model Derail detector mounting structure.
Fig. 3 is enlarged drawing at the I of Fig. 2.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model Derail detector includes through mounting base 8 across being mounted on bogie frame
The transition crossbeam 1 at 2 middle parts, the transition crossbeam 1 be include the i shaped steel structure of upper beam 11 and underbeam 12, and the transition crossbeam 1
Sensor mount 121 is set with wheel corresponding position on the lower section of traction electric machine 3, the underbeam 12 of the transition crossbeam 1, it should
Pressure sensor 5 is set in sensor mount 121, and pressure sensor 5 includes pressure sensing cell and signal processing unit, is somebody's turn to do
The signal processing unit output cable 7 of pressure sensor 5 is connected to train control system；Positioned at 121 bottom of sensor mount
Underbeam 12 on the longitudinal detection hole 122 for running through underbeam 12 of setting, spring 4, the top of the spring 4 are set in the detection hole 122
The pressure sensing cell of pressure sensor 5 is connected, spring mounting plate 6 is arranged in bottom.The specifically used situation of the utility model are as follows:
(1), for train when operating normally, spring 4 is in free state, and pressure sensor 5 is not felt by the pressure of spring 4
Power, will not alert, pressure sensor 5 only issues normal operation signal, this signal is sent to column by output cable 7
Vehicle control.
(2), when train derails, bogie and its framework 2 fall down rail, since transition crossbeam 1 is installed on steering structure
The lower section of the traction electric machine 3 of frame 2, thus transition crossbeam 1 is contacted with rail first, so as to protect traction electric machine 3 and other zero
Component is not damaged, substantially increases the travel safety of train.Certainly, more specifically, the component of rail is contacted at first
The spring mounting plate 6 being mounted on transition crossbeam 1, and then compressed spring 4, the compression of spring 4 one generate pressure and are transmitted to pressure
Sensor 5, when pressure is more than limit value, pressure sensor 5 issues alarm signal, and alarm signal is sent to by output cable 7
Train control system, staff receive warning message and carry out parking checking to train；
(3), in order to further improve the safety in operation of rail vehicle, the output of the utility model Derail detector
Cable 7 is connected with train monitoring center (not shown), train monitoring center receive signal latter aspect can be transmitted signal to
Train control system controls the speed and braking operation of train by train control system, on the other hand also capable of emitting alarm signal
Number, it reminds operator to carry out relevant operation, to guarantee train safety, reduces because human factor leads to the danger of train driving
It is dangerous, reduce the labor intensity of staff.
In order to preferably protect bogie part in derailing, a set of derailing inspection can be installed below each traction electric machine
Device is surveyed, two traction electric machines and driving unit can be protected simultaneously in this way.
The triggering mode of the utility model Derail detector can also change travel switch by spring 4 and pressure sensor 5
Or valve block.
