Description

The use of curtain floors, located above the main floor of the car and moved across it by means of an endless screw, to the mechanical unloading of cars, is in itself known. The peculiarity of the proposed open platform wagon of this kind is mainly the arrangement of the mechanism for moving the curved floor by means of paws mounted on carriages moving back and forth across the car under the influence of the associated rocker arm, which receives a rocking motion from an endless screw. one way, then the other way.

In FIG. 1 and 2 depict a front view of the proposed car, one with the normal position of the curtain floor, and another with the floor rolling for unloading; FIG. 3- the top view of the car also during unloading; FIG. 4-side view of the carriage with dogs; FIG. 5 is a top view of the carriages and their moving mechanism.

Above the constant floor of an ordinary commodity car for loose cargoes (platforms) transported in the open, a second movable curtain floor / with boards on each side consisting of a series of boards, hinged together with each other, is installed. This double floor can

moving across the car, rolling on the rollers 2, located on several crossbars 3, fixed on a fixed floor (Fig. 1, 2, 3). When moving through the mechanism described below, the blind NOL, assuming the position shown in FIG. 2, dumps the load lying on it to one side or the other from the car at some distance from it. The moving mechanism device located in the space between the main and mobile floors and thus sufficiently protected is as follows (Figs. 3, 4 and 5) . For each of the four guides, reinforced in pairs on the main floor of the car, across it, a pair of carriages 4, 4 can be moved together, each equipped with two dogs 5, 5. The dogs of each carriage are turned in different directions and each works only in one direction. Both carriages on one guide rail are connected permanently to each other, and by means of a 15 L hinged joint with opposite ends of the three-arm rocker arm 10, located between two adjacent rail guides and swinging on the axis 12. The third arm 11 of the rocker is perpendicular to it (shank) , its fork end covers the nut 14 of the drive endless screw / 3,

installed longitudinally on the constant floor of the car near its lateral edge and driven manually by means of a steering wheel.

Due to such a device; when the screw 13 is rotated, the carriages connected to one beam, but located on different guides, move in opposite directions (Fig. 3). The spring-loaded pawns 5 pivotally mounted on the carriages, during their working stroke, abut against the staggered protrusions 9 on the lower sides of the curtain floor boards and thus move it across the carriage; when the carriages reverse idle, these dogs, turning a little on their axes 7, can freely pass below the indicated protrusions 9, and with the beginning of a new working stroke are driven by their springs 6 again to the working position.

The screw 13 rotates alternately, one way or the other, so the carriages and their paws move forward, in the direction of moving the curtain floor, then backwards, in order to reverse the screw to the opposite, to start their working operation again. As the carriages and dogs move forward alternately, one or the other, immediately replacing each other, their movement of the curtain floor is continuous.

Dogs, as has been said, are turned in opposite directions. When rolling the curtain floor in a known direction, the dogs corresponding to the ETOL1 in the direction are left in the normal standing position, while the rest for the other direction - turning them on the axis by means of the screw 8 (Fig. 4) is lowered inside the carriage and locked in the position shown in fig. 4 dotted line.

The unloading of the car is carried out by manually rotating the endless screw 13 into one or the other side, as far as the corresponding length of the cut part of it allows. 14 screw nut, moving

back and forth and working through the yoke, causes the latter to swing and move one carriage 4, 4 on the side of the working stroke, and the other back. The corresponding dogs 5 capture the bottom of the curtain floor and move it across the car in the desired direction. Rolling over the edge of a permanent floor, the schtorny floor with its side hooks behind the hooks fortified on the sides of the car, and the load rolls away from the car. So that the curtain floor does not descend from the wagon and, in order to turn around, does not touch the ground, its lateral movement is limited to prices of a certain length, connecting its side boards with the wagon frame. The reverse setting of the curtain floor to the car after unloading is performed in the same way, i.e. by rotating the endless screw with the corresponding only switching dogs.

The subject matter of the invention.
