Description

one

The invention relates to devices for the mechanization of track work, can be used in mining industry for the dismantling of railway tracks in quarries, as well as in industrial railway transport.

The purpose of the invention is to reduce energy costs by reducing traction.

Figure 1 shows the device when the upper track; figure 2 is the same, side view; on fig.Z - the same, front view.

The proposed device comprises a movable frame 1 mounted on it by means of a hinge 2 with the ability of the actuator 3 to move in a vertical plane, perpendicular to the axis of the track, a working body made in the form of two knives 4 and 5 located on both sides of the platform relative to its longitudinal axis. Moreover, the angle aS of the wedge of the front knife 4 is smaller than the angle / wedge of the rear knife 5. The vibrators 6 are rigidly fixed on the knives 4 and 5.

During operation, a thrust force is applied to frame 1 and it begins to move along the track. The vibrators 6 and 3 are driven by the front 4 and rear 5 knives, fastened 162682

On the frame i with the help of hinges 2, they are lowered and set under the path. vuyu lattice. When the cutting edges of knives 4 and 5 occupy horizontal

5 position, the grate is lifted with knives. The bottom surface of the knives 4 and 5 coincides with the plane of the lower surfaces of the sleepers. On the track grid, in place of contact} and knives 4 and 5 with sleepers, elevated waves are generated, which move as the device advances. The front knife 4 with an angle of 5b of the wedge equal, for example, 15 5-8, moving under one rail thread, makes a preliminary tearing of the sleepers on one side, and the rear knife 5 with an angle of 3 wedges equal to, for example, 10-20 °, routine

20 under the second rail thread, finally separates the track grid from the frozen ground, since the angle / wedge of the back knife is greater than the angle of the wedge of the front knife, therefore, the back knife has a greater thickness than the front one and raises the rail sleeper to a great height lattice, separating it from the ground. Placing the knife first

30 movement with a smaller wedge angle reduces energy costs when the grating paths are torn off due to a decrease in pulling force.
