Description
Technical field
The invention belongs to detection fields, and in particular to cement detection field is related to a kind of adjustable aperture-type diameter measurement
Instrument.
Background technique
Flow of cement mortar is a kind of measurement for indicating cement mortar mobility, and under certain amount of water, fluidity is taken
Certainly in the water requiremen of cement.The average diameter (MM) that fluidity is extended on flowing table with cement mortar indicates.Surveying cement gel
When sand fluidity and manual sand patch method survey pavement structural depth formed diameter of a circle, diameter survey generally is carried out with vernier caliper
Amount, the accuracy measured in this way is lower, and extremely inconvenient, and cement holds slide calliper rule easy to stick or operator.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of adjustable aperture-type measuring apparatus of diameter, can be realized cement gel
The precise measurement of sand fluidity diameter.
Specific embodiment:
A kind of adjustable aperture-type measuring apparatus of diameter, which is characterized in that including iron stand, the adjustable light source of aperture, angle measurement
Instrument, the adjustable light source of the aperture and angel measuring instrument are connect by clip with iron stand, the neutral conductor of the angel measuring instrument
With at the neutral conductor of the adjustable light source of aperture on the same line.
Further, the top of the adjustable light source of aperture is arranged in the angel measuring instrument, is arranged on the iron stand vertical bar
There is graduated scale.
Further, the adjustable light source of the aperture includes power supply unit, illumination region, zoom ring and Zoom optic lens, described
Power supply unit, illumination region, zoom ring and Zoom optic lens are set gradually from top to bottom, are similar to aperture adjustable flashlight and are filled
It sets.
Further, the angel measuring instrument is Digit Display Angle Ruler, a Zhi Qianduan of the Digit Display Angle Ruler installation digital display instrument
It is provided with infrared laser pen.
Further, the light that the adjustable light source of aperture issues is colored light, such as red, green, yellow, blue colored light sources.
The utility model has the advantages that the present invention is able to carry out the precise measurement of flow of cement mortar diameter；Easy to operate, effect is good.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention；
Fig. 2 is enlarged drawing at A；
Wherein, 1 iron stand；2 power supply units；3 illumination regions；4 zoom rings；5 Zoom optic lens；6 digital display instruments；7 infrared laser pens；8
Digit Display Angle Ruler.
Specific embodiment
A kind of adjustable aperture-type measuring apparatus of diameter as shown in Figure 1, including the adjustable light source of iron stand 1, aperture, angle
Measuring instrument, the adjustable light source of the aperture and angel measuring instrument are connect by clip with iron stand, in the angel measuring instrument
At the neutral conductor of property line and the adjustable light source of aperture on the same line.
Further, the top of the adjustable light source of aperture is arranged in the angel measuring instrument, is arranged on 1 vertical bar of iron stand
There is graduated scale.
Further, the adjustable light source of the aperture includes power supply unit 2, illumination region 3, zoom ring 4 and Zoom optic lens 5,
The power supply unit 2, illumination region 3, zoom ring 4 and Zoom optic lens 5 are set gradually from top to bottom.
Further, the angel measuring instrument is Digit Display Angle Ruler 8, and the one of the installation of Digit Display Angle Ruler 8 digital display instrument 6 supports the front
End is provided with infrared laser pen 7.
Operating principle of the invention:
By taking the adjustable light source of aperture of power supply unit 2, illumination region 3, zoom ring 4 and Zoom optic lens composition as an example, by digital display angle
It spends ruler 8 and is used as angel measuring instrument, infrared laser pen 7 is set in the front end that Digit Display Angle Ruler 8 installs digital display instrument 6.
The adjustable light source of aperture, angel measuring instrument are arranged on iron clamp platform 1 by clip, guaranteed in angel measuring instrument
The neutral conductor of property line and the adjustable light source of aperture is in same vertical straight line.
The hot spot of the adjustable light source of aperture is transferred to minimum by zoom ring 4, cement mortar is placed at the center of hot spot,
So that cement mortar disperses around, the size of hot spot is adjusted by focal length ring 4, so that hot spot and cement mortar form figure wheel
Wide approximate circle size is close (can suitably to move iron stand, so that the center of the adjustable light source of aperture and cement mortar form and scheme
Shape profile approximation circle center is overlapped), setting infrared laser pen 7 in adjustment 8 front end of Digit Display Angle Ruler is overlapped with hot spot edge, measures angle
Degree can calculate cement mortar in conjunction with triangle relevant knowledge by measuring the height h on 8 top of Digit Display Angle Ruler and platform
Form the radius r of graph outline approximation circle.It is logical by the adjustable light source of rotation measuring Digit Display Angle Ruler 8(aperture, angel measuring instrument
Bearing is crossed to connect with iron stand clip) it can repeatedly measure, it is averaged, so that result is more accurate.The adjustable light source of aperture
The light of sending is that colored light, such as red, green, yellow, blue colored light sources are kept away convenient for measuring on daytime (when natural light)
Exempt from the interference of natural light.
