Description
Technical field
The present invention relates to a kind of parking braking to examine ramp slope angle detection means.
Background technology
The inspection of motor vehicle performance of parking brake is the important detection project of motor vehicle, according to《Vehicle Security is examined
Project and method》（GB21861-2014）Regulation, motor vehicle performance of parking brake, which is examined, to use parking braking to examine ramp
Method, i.e., motor vehicle is parked in positive and negative both direction on the ramp with certain slope angle and remains stationary more than 5min.In order to
Ensure the accuracy of motor vehicle performance of parking brake inspection, it is necessary to carry out periodic detection to the slope angle in ramp, measure ramp at present
The most frequently used method of slope angle is detected using slope angle instrument, is needed slope angle instrument being placed on ramp during measurement and is carried out reading, by
The slope angle in a bit of ramp can only be reacted in slope angle instrument, for ramp longer for those and inconsistent slope angle, if it is desired to
Comprehensively measure the slope angle situation in whole ramp, it is necessary to repeatedly placed in different positions slope angle instrument carry out reading, workload compared with
Greatly, and slope angle instrument measurement slope angle is contact measurement, if ramp surface flatness is bad, can influence the degree of accuracy of measurement.
The content of the invention
In order to more easily and accurately determine the slope angle value in ramp, the present invention uses following technical scheme：Apparatus of the present invention
Including leveling worktable, displacement transducer, laser sensor, signal picker and computer, wherein, displacement transducer is fixed on
On the chuck of leveling worktable, laser sensor is secured in place on the platform on the measuring jaw of displacement sensor, synchronous up and down with measuring jaw
It is mobile.The displacement transducer and laser sensor selected in the present invention carry data transmission interface, by with signal acquisition
The data wire of device is connected with computer, can be in real time by surveyed data transfer into computer.Apparatus of the present invention are using such as
The angle of gradient in lower scheme measurement parking braking ramp：Leveling worktable is used for the leveling of whole device, after device leveling, makes
It is used for determining the change of the upright position of difference on ramp with displacement transducer△h, laser sensor be used for determine horizontal position
The change put△l, by the data transfer measured into computer, according to trigonometric function formulaα=arctanTo measure slope angle
The present invention can realize the multistage measurement to long range ramp, and main advantage is：（1）Without artificial reading, data are led
Enter computer disposal, workload is small, and measurement is accurate；（2）Non-cpntact measurement, do not influenceed, measured by tested ramp surface appearance
As a result it is more accurate；（3）Equipment is simple, easy to operate and portable.
Brief description of the drawings：

Make platform 2 and be provided with levelling bolt 3 and rotating disk 4, by rotating levelling bolt 3 come the levelness of adjusting apparatus, by shaking rotating disk 4
It can rotate horizontally chuck 2, platform 7 is housed on the measuring jaw 8 of displacement transducer 5, laser sensor 6 is fixed on platform 7.
Fig. 2 is using schematic diagram during apparatus of the present invention measure slope angle
Wherein, 9 be displacement transducer signal collector, and 10 be laser sensor signal picker, and 11 be computer, and 12 be data
Line.
Embodiment：
Apparatus of the present invention measure the horizontal range of each measurement point on ramp by using displacement transducer 5 and laser sensor 6
And the difference of height calculates the slope angle in this section of ramp.In this example, exemplified by choosing three measurement points by two sections of ramps of measurement
Explain：
（1）Such as Fig. 2, by the domatic placement of present apparatus face, the light beam of laser sensor 6 is set to be radiated on domatic, using being connected with
Displacement transducer 5, laser sensor 6 are connected by the data wire 12 of signal picker 9,10 respectively at computer 10, pass through laser
The horizontal inducing function that sensor 6 carries carrys out the Realize of observation device, rotates the levelling bolt 3 of leveling worktable 2 to adjust
The levelness of engagement positions, adjusted until being shown on laser sensor 6 to horizontal level.
（2）By the laser sensor of measuring jaw 8 for shaking rotating disk 4 and moving displacement sensor 5 on leveling worktable 1
6 laser beam alignment point A, press laser sensor 6 signal picker 10 measure now rangefinder to the horizontal range of A pointsl a , then press displacement transducer 5 signal picker survey 9 now displacement transducer 5 measuring jaw height and positionsh a 。
（3）The measuring jaw 8 of moving displacement sensor 5, make laser beam alignment point B, press displacement transducer 5 and laser sensing
The signal picker 9,10 of device 6, measure now laser beam alignment point B horizontal rangel b And height and positionh b , now, calculate
Machine 11 can utilize formula according to resulting dataα ab=arctan, A points are measured to the slope angle in ramp between B points.
（4）The measuring jaw 8 of displacement transducer 5 is continued to move to, makes laser beam alignment point C, use and step（3）Same side
Method, measurel c Withh c , B points are finally given to the slope angle in ramp between C pointsα bc。
