Description

Механические рейсшины, выполненные в виде двух шарнирно сочлененных рамок, несущих четыре шкива, соединенных гибкой св зью, на одном из которых смонтирована поворотна  головка дл  линеек, известны .Mechanical troughs, made in the form of two articulated frames, carrying four pulleys connected by a flexible link, on one of which a turning head for rulers is mounted, are known.

Предлагаема  механическа  рейсшина отличаетс  от известных тем, что головка снабжена кулачком, управл ющим запорной собачкой поворота головки и через сухари разрезной втулкой фрикционного тормоза голо-вкн.The proposed mechanical tailing is different from those known in that the head is equipped with a cam controlling the locking paw of the head rotation and through the crackers with a split sleeve of the friction brake of the holo-vkn.

На фиг. 1 показана схема рейсшины; на фиг. 2 - вид сбоку с частичным разрезом головки рейсшины; на фиг. 3 - вид сверху.FIG. 1 shows a rail drawing; in fig. 2 is a side view with a partial section of the T-square head; in fig. 3 - top view.

Рейсшина выполнена в виде дзух шарнирно сочлененных рамок. Рамки несут соединенные между собой гибкой св зью 2 неподвижно закрепленный шкив 3 и шкивы 4, 5 и 6. На шкиве 6 монтируетс  поворотна  головка дл  линеек 7, ось / которой несет втулку 8 профилированного кулачка 11. Кулачок через ролик 10 и планку 9 управл ет запорной собачкой 12 поворота головки , а посредством сухарей 13 разрезной втулкой 14 фрикционного тормоза головки.T-square made in the form of Dzuh articulated frames. The frames carry interconnected flexible pulley 3 and pulleys 4, 5 and 6 connected by a flexible link 2. On the pulley 6 a swivel head for rulers 7 is mounted, the axis / of which carries sleeve 8 of the profiled cam 11. The cam 10 controls the locking dog 12 rotates the head, and through the crackers 13 split sleeve 14 of the friction brake head.

Поворачива  левой рукой маховичок против часовой стрелки на уголTurn the handwheel with your left hand counterclockwise at an angle

15-18°, собачка 12 кулачком j выводитс  из зацеплени  с зубчатым сектором 15.15-18 °, the pawl 12 by the cam j is disengaged from the toothed sector 15.

Поворачива  маховичок по часовой стрелке на 10-12°, ролик 10 западает в соответствующую впадит;у кулачка.Turning the handwheel in a clockwise direction by 10-12 °, roller 10 falls into the corresponding one; at the cam.

При повороте маховичка по часовой стрелке на 25-30° сектор перемещает ролик, а также линейки. При этом кулачок отжимает сухари 13, в результате чего втулка 14 разЛ имаетс  и фиксирует положение линеек.When the handwheel is rotated clockwise by 25-30 °, the sector moves the roller, as well as the rulers. In this case, the cam presses the crackers 13, as a result of which the sleeve 14 is folded and fixes the position of the rulers.
