Description

Обычно примен емые в геодезических инструментах дл  отсчета параллактических углов тангенциальные микрометренные винты обладают тем существенным недостатком, что с увеличением абсолютного значени  измер емого угла (до Ю-12) абсолютна  точность измерени  уменьшаетс . Поэтому тангенциальные винты дл  отсчета углов рационально примен ть лишь дл  диапазона от О дог 4,5°.Tangential micrometre screws commonly used in geodetic instruments for reading parallax angles have the essential disadvantage that as the absolute value of the measured angle increases (up to 10-12), the absolute accuracy of the measurement decreases. Therefore, it is rational to use tangential screws for counting angles only for the range from 0 to a dog of 4.5 °.

Предметом насто щего изобретени   вл етс  приспособление дл  отсчета параллактических углов поворота алидады геодезического инструмента , допускающее измерение без уменьшени  абсолютной точности последнего, с увеличением абсолютной величины измер емого угла, примерно, до -22°. С этой целью приспособление имеет микрометр, винт которого всегда располагаетс  по хорде измер емой дуги (угла).The object of the present invention is a device for counting the parallax angles of rotation of the geodetic instrument alidade, which can be measured without decreasing the absolute accuracy of the latter, with an increase in the absolute value of the measured angle to approximately -22 °. For this purpose, the device has a micrometer, the screw of which is always located along the chord of the measured arc (angle).

Предлагаемое, согласно изобретению , приспособление представлено на чертеже, причем фиг. 1 изображает вид его сверху и фиг, 2 - вид сбоку.The device according to the invention is represented in the drawing, with FIG. 1 is a top view of it and FIG. 2 is a side view.

Обойма 1 винта 3 находитс  над лимбом инструмента в горизонтальном положении и может вращатьс  в плоскости азимутальных углов вокруг вертикальной конусной цапфы 6, расположенной в конусном подп тнике лимба или трегера инструмента .The yoke 1 of the screw 3 is above the tool limb in a horizontal position and can rotate in the plane of the azimuthal angles around a vertical conical axle 6, located in the conical hollow of the limb or treger of the tool.

Вдоль обоймы / винтом 3 перемещаетс  ползун 2, снабженный цапфой 5, поворотно соедин емой с алидадой инструмента. Ползун 2 снабжен нониусной шкалой 9 грубого отсчета по шкале 4, укрепленной на обойме /. Дл  точного отсчета угла винт 5 снабжен барабанчиком 8 с нанесенной на его цилиндрической поверхности шкалой, отсчет по которой производитс  по нониусу 7, укрепленному на обойме 1.Along the sleeve / screw 3, a slider 2 is moved, provided with a pin 5, pivotally connected to the alidade of the tool. The slider 2 is equipped with a nonius scale 9 rough reading on a scale 4, strengthened on the holder /. In order to accurately read the angle, the screw 5 is provided with a drum 8 with a scale applied on its cylindrical surface, which is read by the nonius 7 mounted on the holder 1.

Предмет изобретени .The subject matter of the invention.

Приспособление к геодезическим инструментам дл  отсчета углов поворота алидады по хордам, выполненное в виде микрометренного винта с нониусом, отличающеес  тем, что обойма 1 и ползун 2, несущие нониусную шкалу 9 и микрометренный винт 3, снабжены цапфами б и 5, из коих перва  соединена с лимбом, а втора  - с алидадой. Е авторскому свидетельству Я. № 55152 Д. МакарчукAn adaptation to geodetic instruments for counting the angles of rotation of the alidade along chords, made in the form of a micrometer screw with a vernier, characterized in that the holder 1 and the slider 2, carrying the vernier scale 9 and the micrometer screw 3, are fitted with trunks b and 5, of which the first scale is connected with limb, and the second - with alidade.
