Description

The invention relates to railway transport and the design of devices for lifting and shifting the track grid.

Devices for lifting and shifting a railroad track are known, comprising rail clamps mounted on a frame of a railcar and connected with lifting shoes of lifting and shifting power cylinders.

For drying, the power cylinders are arranged asymmetrically with respect to the bogie axlerams, and each of them is equipped with an individual support shoe and locking cylinder, with the fixing cylinders angled to the bogie frame and opposite each other.

FIG. 1 schematically shows this device, a general view; in fig. 2 - the same, top view; in fig. 3 - the same, in the working position (when shifting the path); in fig. 4 - the same, when performing an exact straightening of the path.

On the frame 1, made in the form of a rectangle with windows, rail clamps 2 and hydraulic cylinders 3 and 4 are mounted for mounting and fixing asymmetrically located power cylinders 5 and 6, in the lower part of which support shoes 9 and 10 with ribs are hinged on the rods 7 and 8 And and clamps 12. The locking cylinder 3 is hinged at one end through a pin 13 to

frame 1, and the other through pin 14 to the power cylinder 6. The locking cylinder 4 is attached similarly through pin 15 to frame 1, and through pin 16 to the power cylinder.

When this cylinder 3 and 4 are located relative to each other and counter at an angle to the frame of the trolley.

For lifting the way the power cylinders 5 and 6 are mounted in a vertical position

and fixed by cylinders 3 and 4. Rods 7 and 8 with support shoes 9 and 10 are lowered and, resting against the ballast of sleeping persons, raise the track grid 17, previously gripped by rail grippers 2. When the track is straightened, for example, to the right, the power cylinder 5 bends the side of the straightening cylinder 4. The force of the straightening created by the power cylinder 5 in an oblique position when the rod 7 moves, through the support shoe 9, the frame 1 and the rail clamps 2 is transmitted to the rails. The pitch of the straightening and the force acting on the rails change when the tilt angle of the power cylinder 5 changes. The straightening of the path under difficult conditions can be carried out by two power cylinders 5 and 6 at the same time, while they must both be tilted in the direction of the straightening. The movement of the track can be performed in any direction in a stepwise manner continuously by alternating

activation of the power cylinders 5 and 6

Subject invention

A device for lifting and shifting a railroad track, comprising rail-clamps mounted on the frame of a railcar and connected to support shoes of lifting and shifting power cylinders, distinguished by the fact that in order to carry out 458

No continuous displacement of the track, the power cylinders are located asymmetrically with respect to the axes of the trolley frame and each of them is equipped with an individual support bar and a locking cylinder, with the locking cylinders angled to the frame of the trolley and opposite to each other.
