Description
Предлагаетс центровочный отвес, в верхней части которого находитс катушка дл наматывани шнура с пластинчатой тормоз щей пружиной, удерживаюша отвес от произвольного опускани .A centering plummet is proposed, in the upper part of which there is a coil for winding a cord with a plate-braking spring, keeping the plummet from arbitrary lowering.
Описываемый отвес отличаетс тем, что его можно свободно передвигать вверх или вниз, не отв зыва шнур в точке привеса, что особенно удобно при маркшейдерских подземных съемках, когда центрировка производитс над теодолитом и передвижка отвеса измер етс в миллиметрах.The plumbing described is distinguished by the fact that it can be freely moved up or down without disconnecting the cord at the gain point, which is especially convenient for surveying underground surveys when centering is performed on the theodolite and moving the plumb line is measured in millimeters.
На фиг. 1 и 2 изображен центрировочный отвес с наматывающимс шнуром.FIG. 1 and 2 depict a centering plumb with a winding cord.
Металлический отвес / в верхней части имеет полость, в которую вставлена катушка 2, вращающа с на оси 3, укрепленной в корпусе отвеса /. На оси 3 установлены две спиральные пружшгы 4, помешенные между корпусом отвеса / и катушкой 2, создающие тормоз ший момент при вращении катущки 2. Боковые стенки 5 катушки 2 выполнены в виде храповых колес, собачкой дл которых служит изогнута пружина 6. Отвес / в нижней части имеет иглу 7, а в верхней части отверстие 8, служащее дл прохождени шнура от катушки к месту привеса.The metal plumb / in the upper part has a cavity into which the coil 2 is inserted, rotating on axis 3 fixed in the plumb body /. Axis 3 has two coil springs 4 placed between the plumb body / and coil 2, creating a braking torque when the coil 2 rotates. The side walls 5 of the coil 2 are made in the form of ratchet wheels, the bent spring 6 serves as a pawl. the part has a needle 7, and in the upper part an opening 8, which serves to pass the cord from the reel to the weight gain.
Предмет изобретени Subject invention
Центровочный отвес с катушкой дл наматывани ишура, о тчающийс тем, что, с целью установки и удержани отвеса на требуемой высоте, катущка снабжена пластинчатой тормоз щей пружиной.A centering plumb with a coil for winding the ishura, which is due to the fact that, in order to install and hold the plumb at the required height, the coil is equipped with a plate-braking spring.
