Description
ный от перн.метра вырабогкн снег попадает в объектив зрительной трубы 2 через линзы 7, 8 и 9, и на стекл нной нластине 18 через окул р наблюдают в онределенном масштабе сечение выработки .Затем с номощью ходовых гаек 21, винтов 17 н 23, конических шестерен 15, 16, 24 и 25 перемешают рамку 13 так, чтобы нолучить удобный отсчет площади измер емого сечени выработки исчисл емой ио масштабной сетке нластииы 18. Так как масштаб каждой клетки известен, то сразу же онредел ют искомую плош,адь сечени .From the first meter, the snow penetrates the lens of the telescope 2 through lenses 7, 8 and 9, and on the glass nlastina 18 through the eye is observed on a definite scale, the output section. Then with the help of traveling nuts 21, screws 17 and 23, conical Gears 15, 16, 24, and 25 mix frame 13 so as to obtain a convenient reading of the area of the measured section of the output of the estimated 18 scale grid of the 18th section. Since the scale of each cell is known, it immediately determines the desired full section.
Дл удобства измерений зрительную трубу 2 можно ноБора.чивать в горизонтальной и вертикальной плоскост х.For convenience of measurement, the telescope 2 can be bordered in horizontal and vertical planes.
Предмет изобретени Устройство дл из.мерений плои,ади сеченнй горных выработок, содержан ее корпус и оптическую систему, отличающеес тем, что, с целью увеличени точности и снижени трудоемкости измерени , оно снабжено съе.мной рамкой с масштабной сеткой и механизмом ее регулнровки в вертикальной плоскости, размещенным в , котора вынолнена в корпусе .The subject of the invention The device for measuring the thickness of the mine workings, contains its body and optical system, characterized in that, in order to increase accuracy and reduce the labor intensity of the measurement, it is equipped with a removable frame with a large-scale grid and a mechanism for its adjustment in vertical plane placed in, which is made in the housing.
