Location when described detected mine lamp and light fixture fixed head are fixed, is utilize outstanding charging screw on detected mine lamp to coordinate with the short slot being arranged on locating piece on light fixture fixed head, makes detected mine lamp location in a rotational direction.
Described turning rack plate is provided with vertical rotary positive stop strip, base plate before and after vertical rotary positive stop strip in slewing area is fixed with the proximity switch lower than vertical rotary positive stop strip, when above positive stop strip moves to proximity switch, export limit signal, to limit detected mine lamp vertical rotation angle and to the right left.
Described rotation axis is provided with and horizontally rotates stop means.
The described stop means that horizontally rotates is fixed with two panels spacer on the rotating shaft, every sheet spacer is shaped with through hole or breach, is provided with photoelectric sensor in the side of spacer, to limit the angle horizontally rotated up and down of detected mine lamp respectively.
According to mine lamp luminous intensity and the proving installation of illumination of such scheme design, clamped one time can be realized and complete illumination to each point in detected mine lamp range of exposures and light intensity test.Conveniently can realize the display of LCD graphic dot matrix, the angle in the current level of detected mine lamp and vertical direction can be shown simultaneously, and corresponding illumination and light intensity etc.The test data of detection probe gained, transfer on demand or transfer in computer, with supporting software, data are further processed in computer, can generating report forms, X-Y scheme or dynamic 3 D graphics, for the full-automation of mine lamp luminous intensity and illumination test provides key device.
During use, user can test or full test on demand fast.During quick test, proving installation only to the test event specified in mine lamp national standard and test point image data, can complete the test meeting mine lamp national standard in the shortest time.During full test, proving installation gathers point data each in hot spot gamut in the mode of scanning, can obtain more comprehensively and data accurately.
