(54) DEVICE FOR FIXING THE RAILBOARDS OF THE UNTILED PATH

BACKGROUND OF THE INVENTION The invention relates to devices for laying a continuous joint.

 A device for fixing rail lashes of a continuous path, containing brackets, is attached. to the elements of the path, and the fastening elements of these lashes to the brackets

However, the known device for fixing rail lashes of the endless KOBord track is cumbersome, has many parts and is used only at the time of unloading from the rolling stock. It is not suitable and not used for fixing rail lashes discharged into the rail before they are laid, as it does not ensure the safety of trains on the current track (long cable for hanging parts of the cargo and rolling stock). The device requires isolation on self-locking lines.

The purpose of the invention is to control the efficiency of the device by securing the lash relative to the sleepers.

This goal is achieved by the fact that the configuration of each bracket corresponds to the cross-section configuration of the cross tie, and in the middle part of the bracket

lining cantilever is attached to accommodate rail lashes and fasteners.

In addition, the middle part of the staple can be made in the form of a screw clamp.

Figure 1 shows the device without rail lashes and terminal bolts, top view; figure 2 - section

10 A-A in Fig. 1; in fig. 3-assembled device with rail braids, top view; figure 4 - section bb in fig.Z.

The device for fixing the rail laps without a joint path connects the brackets 1 attached to the sleepers 2 ways, and the lining 3 cantilever attached to the brackets 1 for rail lashes 4 and fastening elements 5

20 for lashes. The middle part of the staples 1 is in the form of a screw tie b. This creates a rigid attachment of rail lashes to the sleeper of the existing track.

The sleeper, for which the device is attached, has a resistance to longitudinal movements, rests on the ballast, in addition there are additional resistance forces to the fasteners that secure the track rails (6oj | 30

Track mounts are additionally tightened to create maximum resistance to longitudinal movement.

The device is reinforced at both ends of the unloaded lashes and creates forces that prevent the random movement of the lashes.

If the sun lash is located on a firm steep slope, where the forces of longitudinal movement increase, it is possible to additionally install several sets of devices.

The laying of the unloaded rail braids of the continuous track is not made immediately on the day of discharge, but after a while.

From the vibrations of passing trains and their own weight, the whips unloaded on a slope inside the rail track move in the longitudinal direction by a significant amount (up to two meters).

Since the whips of the continuous path have a length of up to 800 m, moving them to their original position, i.e. returning back causes considerable difficulties: locomotives and windows are required in the movement of trains. For work).

If the movement of the lashes is not carried out, the ends of the straps laid in the way of the lashes are cut off, which leads to the damage of the ends of the hardened rail ends. In this case, the cut ends of the rails remain without quenching, wear out quickly, flatten out, which leads to a premature failure of the entire whip of the jointless path.

The proposed device is intended for fixing rail lashes and ensures the safety of train movement, eliminates windows, locomotives for moving the lash into the joint and cutting off the hardened ends of the rail lash, and also displaces the lash of the jointless path before installation.

Technical and economic efficiency: the device is about 2 million rubles. in year.
