Description

There are known devices for translating arrows from a moving and equipped with a lowering shoe of a car using articulated pivotal pivot levers located between the sharks and associated with its non-rigid gear. In the proposed device, the levers are rigidly fastened on the short sides of the hinged four-corners, one of whose long sides is provided with a groove for the first-hand grip rod. When the shoe turns the parallelogram, the quadrangle changes to a rectangle (or vice versa) and no; jychuchuyusche the movement of the long sides of the quadrilateral is used to move the points.

In the schematic drawing of FIG. 1 shows a diagram of the movement of the sides of a quadrilateral with levers; FIG. 2 shows an adaptation from above, FIG. lever part; FIG. Shoe.

The device for translating the arrows from the car consists of a metal hinge (at points 20) quadrilateral (Fig. 1 and 2), the smaller sides 1-1 of which are in the middle, their parts Equipped with Za and 36 levers, turning on the axis x 4 of the quadrilateral. One of the other sides 2-2 of the quadrilateral is provided with a groove 5, which includes a swivel pin / 5 connecting the points 7–7 of the arrow. The entire device is laid on a smooth surface below the level of the tram line and is covered with a lid, and on the surface of the path only levers Za and 36 protrude, rigidly fixed to the smaller sides 7-7 of the quadrilateral at a certain angle. One of the long sides 2-2 of the quadrilateral, having a groove 5 for the finger 6 of the convertible rod / 5, is laid along the middle of the interpath between the cusps so that one of the smaller sides 7-7 with the lever 5a is slightly ahead of the beginning poles 7-7. Attached to the carriage in the front and rear parts (Fig. 4) are the shoes 8-8, which are able, when required, to be lowered or raised, turning around.

When the car approaches the arrow to be transferred, the lowered shoe 8 hits the lever Za and turns it along with the parallelogram 7 rigidly connected with it (Fig. 1), changing the latter into a rectangle, thereby increasing

the distance between the long sides 2–2 and the displacement of these sides, as it were, is obtained, as is used to move the poles with the aid of a transitional rod / 5, connected by a finger to one of the sides of the quadrilateral located along the center of the interstice. If | after the passage of the car, it is required to put the arrow in the same position then. A shoe 8 attached to the rear of the car is lowered, which, by striking the lever 55, changes the quadrilateral from the rectangle to the parallelogram, and the thrust of the 15 puts the edges in the original position.

The subject matter of the invention.

A device for the transfer of arrows from a moving and equipped with a lowering car of the wagon with the use of swiveling, located between the points of the levers; articulated with a driving pull, characterized by the fact that the Za and -Zb levers are rigidly fixed on the short sides of the / -7 articulated quadrilateral having rotation axes 4, and one of the long sides 2 of the quadrilateral is provided with a groove 5 for the finger 6 of the conversion rod 15 (Fig. 2).
