For the purposes, technical schemes and advantages of the disclosure are more clearly understood, below in conjunction with specific embodiment, and reference
The disclosure is further described in attached drawing.
Disclosure some embodiments will be done referring to appended attached drawing in rear and more comprehensively describe to property, some of but not complete
The embodiment in portion will be shown.In fact, the various embodiments of the disclosure can there are many different forms to realize, without that should be solved
It is interpreted as being limited to embodiments set forth herein；Relatively, these embodiments are provided so that the disclosure meets applicable legal requirement.
Fig. 1 diagrammatically illustrates the structural representation of the rail of embodiment of the present disclosure offer and the device of side slope barrier monitoring
Figure.Fig. 2 diagrammatically illustrates the operation schematic diagram of the rail of embodiment of the present disclosure offer and the device of side slope barrier monitoring.Knot
Fig. 2 is closed, the structure described in Fig. 1 is described in detail.
From figure 1 it appears that the rail and the device of side slope barrier monitoring include: laser range finder 1, turntable 2, one
Tie up displacement platform 3, spring 4, ranging machine support 5 and one dimension displacement platform bracket 6.Laser range finder 1, spring 4, is surveyed one dimension displacement platform 3
It is installed on turntable 2 away from machine support 5 and one dimension displacement platform bracket 6, and one dimension displacement platform bracket 6 is fixed on turntable 2, one
Displacement platform 3 is tieed up between one dimension displacement platform bracket 6 and laser range finder 1.
Laser range finder 1 for emitting laser signal by predetermined angle range along above rail and side slope, and is received and is returned
The laser signal returned.For predetermined angle between 0-360 °, laser range finder 1 emits laser signal within the scope of predetermined angle
Purpose is to realize the comprehensive scanning of rail and side slope, for example, laser signal can be from rail one end when predetermined angle is 360 °
Start, side slope around the rail other end and rail is all scanned.Laser range finder 1 is with the near-infrared laser of eye-safe
It, will not be to the train operation and dimension on railway as light source, and in a manner of continuous laser or pulse laser mode emits laser
Shield personnel damage.
Turntable 2, for controlling the rotation of laser range finder 1.When turntable 2 is with default angular speed rotation, turntable 2 passes through survey
Drive laser range finder 1 with default angular speed rotation away from machine support 5, thus control the laser signal of the transmitting of laser range finder 1
Angle realizes that laser range finder 1 emits laser signal within the scope of predetermined angle.For example, when predetermined angle is 360 °, turntable
2 rotational angle is also 360 °.The default angular speed of turntable, such as set angularly step-type angular speed for turntable and carry out
Rotation, can be improved the resolution ratio for the laser signal that laser range finder 1 receives, to improve the rail and side slope in the disclosure
The precision of the device of barrier monitoring.
One dimension displacement platform 3, for controlling the height of laser range finder 1, so that the laser signal that laser range finder 1 emits
Scanning track is broken line.It is that a preset rules, 3 basis of one dimension displacement platform is arranged in one dimension displacement platform 3 according to rail and side slope road conditions
The preset rules control the height of laser range finder 1, so that the scanning track for the laser signal that laser range finder 1 emits and the iron
At a distance of a preset height between rail and side slope, which is the minimum altitude of abnormal barrier.
Abnormal barrier refers to the barrier that will affect passing train safety in rail and side slope, as falling rocks, mountain stone collapse
Deng.The minimum altitude of abnormal barrier refers to the height that the minimum barrier of passing train safety is influenced in rail and side slope.
Preset rules are the sides that the one dimension displacement platform 3 determined after prospecting rail and side slope road conditions controls the height of laser range finder 1
Formula.For example, setting the minimum altitude of certain rail and side slope exception barrier as 5cm, then one dimension displacement platform 3 controls laser range finder
1, laser range finder 1 moves back and forth in its axial direction, so that the scanning track for the laser signal that laser range finder 1 is launched
Always at a distance of 5cm between the rail and side slope；When the height of the barrier on rail and side slope is not less than 5cm, barrier
The laser signal that laser range finder 1 emits is reflexed into laser range finder 1, when laser range finder 1 receives laser signal, laser
Range finder 1 carries out multiple scanning to region locating for barrier, if multiple scanning N (such as N=50) is secondary, laser range finder 1 is still received
To laser signal, then rail and the device of side slope barrier monitoring can judge there is abnormal barrier at this, conversely, if
Before n-th scanning, laser range finder 1 does not receive laser signal, then the device confirmation of rail and the monitoring of side slope barrier should
There is no abnormal barriers at place.
Spring 4, for making laser range finder 1 keep balance.When the back and forth movement in its axial direction of laser range finder 1
When, spring 4 stretches with the back and forth movement of laser range finder 1, so that laser range finder 1 is kept in the radial direction thereof
Balance.
Ranging machine support 5 is used to support laser range finder 1, and drives laser range finder 1 that turntable 2 is followed to rotate.
One dimension displacement platform bracket 6, is used to support one dimension displacement platform 3, so that one end of one dimension displacement platform 3 is fixed.For example,
One dimension displacement platform bracket 6 can be L shape, as shown in Figure 1, in addition, one dimension displacement platform bracket 6 or other shapes.
In addition, the rail and the device of side slope barrier monitoring further include alarm, rail and side slope are monitored for working as
There are when abnormal barrier, alarm signal is issued, convenient for artificial processing in time.
The operation that is monitored of device of rail and the monitoring of side slope barrier includes:
S1 chooses the installation site for the device that a fixed point is monitored as rail and side slope barrier；Determine laser ranging
The predetermined angle that machine 1 rotates；The preset rules of 1 height change of laser range finder are formulated according to rail and side slope road conditions；It determines different
The minimum altitude of normal barrier.
S2, turntable 2 drive to set angular speed within the scope of predetermined angle laser range finder 1 to rotate, one dimension displacement platform 3 with
The height of preset rules change laser range finder 1.
S3, laser range finder 1 emit laser signal, the scanning track of the laser signal and the distance between rail and side slope
It immobilizes, the minimum altitude of as abnormal barrier.
S4, when laser range finder 1 receives laser signal, region that laser range finder 1 monitors the laser signal into
Row multiple scanning, if the continuous n times of laser range finder 1 receive laser signal, alarm issues alarm signal, notice maintenance
Personnel make corresponding processing to abnormal barrier, otherwise, alarm attonity.
