In view of the deficiencies of the prior art, the utility model a kind of measurement error is provided small, nonabradable open circuit of sensor
Device speed measuring device.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of breaker speed measuring device, including breaker kinematic link, sensor waveguide pipe and sensor position magnetic patch,
The sensor waveguide pipe is mounted on tripod, and the clamping group for clamping sensor waveguide pipe is provided on the tripod
Part, the sensor waveguide pipe is interior to be equipped with impulse sender, is fixedly connected with link block on the breaker kinematic link, described
The mounting hole for placing sensor positioning magnetic patch is offered on link block.
Further, the clamp assemblies include the telescopic rod being mounted on tripod, are connected at the top of the telescopic rod
Locating clip frame, the locating clip upper slide of frame is dynamic fixed transverse rod, and the locating clip arch is threaded with for limiting fixation
The abutting bolt of cross bar sliding, one end of the fixed transverse rod is fixedly connected with the holding frame for clamping sensor waveguide pipe.
In this way, recycling locating clip frame to grip cross bar, by sensor using its overall structure of the stability support of tripod
Waveguide is located near range sensor positioning magnetic patch, to be tested the speed using magnetostriction principle.
Further, flexible glue non-slip mat is equipped on the inside of the holding frame.With reinforce sensor waveguide pipe and locating clip frame it
Between frictional force, make waveguide be not easy to fall.
Further, rubber sleeve is set between the mounting hole and sensor positioning magnetic patch.So that positioning magnetic patch is being pacified
Hole wall can be fitted closely in dress hole, and then during the folding of breaker kinematic link is movable, will not be fallen off easily, Huo Zhezhen
It is dynamic, influence the effect finally detected.
The utility model compared with prior art, has the advantages that
The application utilizes magnetostrictive principle, so that when being tested the speed, without being bonded with positioning magnetic patch,
It need to only can be completed and test the speed close to positioning magnetic patch, to will not cause to wear to sensor, while parallel requirement is also not required to
It is so accurate, and because not contacted with the direct of positioning magnetic patch, measurement effect will not be by the vibration of breaker
It moves and influences.

Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
Embodiment
As shown in Figure 1, a kind of breaker speed measuring device, including breaker kinematic link 3, sensor waveguide pipe 2 and biography
Sensor positions magnetic patch 4, and sensor waveguide pipe 2 is mounted on tripod 1, three supporting legs of tripod 1 be it is scalable, pass through branch
Adjusting turncap on leg is adjusted.The clamp assemblies 5 for clamping sensor waveguide pipe 2, sensor are provided on tripod 1
It is equipped with impulse sender (not illustrating to point out in figure) in waveguide 2, is fixedly connected with link block 31 on breaker kinematic link 3,
The mounting hole 311 for placing sensor positioning magnetic patch 4 is offered on link block 31.
Clamp assemblies 5 include the telescopic rod 11 being mounted on tripod 1, and telescopic rod 11 can be adjusted by rotation turncap
Section stretches high height, and locating clip frame 52 is fixedly connected at the top of telescopic rod 11.Locating clip frame 52 is rectangular frame, locating clip frame
Fixed transverse rod 51 is slidably connected in 52, the screw top of locating clip frame 52, which is connected with, pushes against bolt 53.Push against 53 precession of bolt
It presss from both sides inside frame, pushes against fixed transverse rod 51, slide it can not arbitrarily, the head for pushing against bolt 53 is wabbler, facilitates work people
Member turns.
One end of fixed transverse rod 51 is fixedly connected with the holding frame 54 for clamping sensor waveguide pipe 2.Holding frame 54
Shape be cooperate 2 shape of sensor waveguide pipe it is rectangular, holding frame 54 is not connected on one side far from fixed transverse rod 51, this be in order to
When preventing interference sensor from fixing magnetic patch carry out activity, there is interference to measurement structure.It is anti-skidding that one layer of flexible glue is lined in holding frame 54
It pads (not illustrating to point out in figure), is bonded closer, increasing friction force between holding frame 54 and sensor waveguide pipe 2 for making, press from both sides
It obtains more stable.
311 shape of mounting hole on link block 31 is rectangular to match with sensor positioning magnetic patch 4, in mounting hole 311
It is lined with rubber sleeve (not illustrating to point out in figure).Rubber sleeve is for sensor positioning magnetic patch 4 to be smoothly limited in mounting hole 311
Interior, due to the open and close movement of breaker kinematic link 3, sensor positioning magnetic patch 4, which is placed in mounting hole 311, is easy to appear vibration,
Influence is tested the speed as a result, sensor positioning magnetic patch 4 can even deviate from, and addition rubber sleeve can be well solved this problem.
When in use, only need to by sensor position magnetic patch 4 be placed in mounting hole 311, then using tripod 1 with
And sensor waveguide pipe 2 is placed near the travel paths of sensor positioning magnetic patch 4 at 3mm~7mm by clamp assemblies 5 vertically,
It can start to test the speed.
The principle to test the speed is magnetostriction principle: in overall work, the impulse sender in sensor waveguide pipe 2 is issued
One current impulse is added on the waveguide filament in waveguide, and the current impulse is along waveguide filament with light velocity propagation and around waveguide filament
A toroidal magnetic field is generated, when the magnetic field and the intersection of positioning magnetic patch magnetic field, is overlapped mutually and generates a spiral shape magnetic field.Due to
The magnetostrictive effect of waveguide filament, waveguide filament will generate faint torsional deformation under helical magnetic field effect, and with the shape of wave
Formula is propagated with the velocity of sound from intersection to two sides, and the wave of side will be damped device and block and will not reflect, and the wave of the other side then exists
It is detected when reaching wave detector.Since current impulse is with light velocity propagation, the time for reaching positioning magnetic patch ignores, this
Sample detects the time difference of echo by calculating pulsed emission current and wave detector, can further determine that the position of positioning magnetic patch
It sets.
It is tested the speed using the principle, without being bonded with sensor positioning magnetic patch 4, only need to position magnetic close to sensor
Block 4, which can be completed, to test the speed, to will not cause to wear to sensor, while also not needing so precisely to parallel requirement, and
And because with direct the contacting of sensor positioning magnetic patch 4, measurement effect will not by breaker vibration and shadow
It rings.
For above-described embodiment simply to illustrate that the technical ideas and features of the present invention, its purpose is allows this field
Interior those of ordinary skill can understand the content of the utility model and implement accordingly, can not limit the utility model with this
Protection scope.The equivalent changes or modifications that all essence according to the content of the present invention is made, should all cover in this reality
With in novel protection scope.
