The light emitting devices is placed on described measurement gearshift the upper surface of, and the measurement gearshift is installed in hydraulic pressure
On the pedestal of stent, first reflection unit is installed in the inside of the movable post of hydraulic support, and second reflection unit is installed
In the inside of the top beam of hydraulic support.
In addition, the light emitting devices is red light emitting device.
In addition, first reflection unit is reflectance coating, the reflectance coating is attached to the inside of the movable post of the hydraulic support.
In addition, second reflection unit is reflectance coating, the reflectance coating is attached to the inside of the top beam of the hydraulic support.
In addition, the measurement gearshift is graduated scale.
In addition, the light beam that the light emitting devices is sent is reflected through first reflection unit and second reflection unit
The distance between the drop point on the measurement gearshift and the light emitting devices is change in displacement value afterwards, is become according to displacement
Change value calculates hydraulic support descending amount of piston.
By using above-mentioned technical proposal, have the advantages that：
The utility model solves the workload brought in the prior art by manual measurement hydraulic support descending amount of piston
Greatly, the technical issues of efficiency is low low with measurement accuracy, the present embodiment pass through light emitting devices, the first reflection unit, the second reflection
Device and measurement gearshift have carried out accurate measurement to hydraulic support descending amount of piston, enable staff according to hydraulic pressure
The Assessment of Changes roof of stent descending amount of piston presses rule.
Description of the drawings
Fig. 1 is the monitoring device for the hydraulic support descending amount of piston that the utility model one embodiment provides.
Specific embodiment
The utility model is further described in detail below in conjunction with specific embodiment and attached drawing.It is only intended in detail
The thin specific embodiment for illustrating the utility model, does not generate any restrictions, the protection of the utility model to the utility model
Scope is subject to claims.
With reference to Fig. 1, the utility model proposes a kind of monitoring device of hydraulic support descending amount of piston, including：
Light emitting devices 4, the first reflection unit 7, the second reflection unit 6 and measurement gearshift 5；
Light emitting devices 4 is placed on measurement gearshift 5 the upper surface of, and measurement gearshift 5 is installed in the bottom of hydraulic support
On seat 3, the first reflection unit 7 is installed in the inside of the movable post 2 of hydraulic support, and the second reflection unit 6 is installed in hydraulic support
The inside of top beam 1.
Light emitting devices 4 emits light or light beam, and light is by being installed in the first of the inside of the movable post 2 of hydraulic support
After the reflection of reflection unit 7, after the reflection using the second reflection unit 6 of the inside for the top beam 1 for being installed in hydraulic support, light
Line falls on measurement gearshift 5, records the position, and the distance between the position and 4 position of light emitting devices are
Change in displacement value D1, the value of hydraulic support descending amount of piston D2 is calculated by formula D2=D1tan α, and wherein α is light emitting devices
Acute angle between 4 light and horizontal plane sent in angle.
The present embodiment can solve the workload brought in the prior art by manual measurement hydraulic support descending amount of piston
Greatly, the technical issues of efficiency is low low with measurement accuracy, the present embodiment are anti-by light emitting devices 4, the first reflection unit 7, second
Injection device 6 and measurement gearshift 5 accurate measurement has been carried out to hydraulic support descending amount of piston, enable staff according to
The Assessment of Changes roof of hydraulic support descending amount of piston presses rule.
In one of which embodiment, light emitting devices 4 is red light emitting device.
Since feux rouges is the longer light of light wave, so selection feux rouges is emitted.
In one of which embodiment, the first reflection unit 7 is reflectance coating, and reflectance coating is attached to the movable post 2 of hydraulic support
Inside.
By way of pasting reflectance coating the inside of the movable post 2 in hydraulic support, save and placed the first reflection unit 7
Space, while the structure of movable post 2 will not be destroyed by way of stickup.
In one of which embodiment, the second reflection unit 6 is reflectance coating, and reflectance coating is attached to the top beam 1 of hydraulic support
Inside.
By way of pasting reflectance coating the inside of the top beam 1 in hydraulic support, save and placed the second reflection unit 6
Space, while the structure of top beam 1 will not be destroyed by way of stickup.
