Abstract

The invention relates to the topside structure primarily for the subway. The purpose of the invention is to improve the efficiency of damping rail oscillations and to reduce the level of noise during the passage of rolling stock. The upper structure of the track contains rails 1 with fasteners laid on the bog beds 2 mounted on a rigid base 3 by means of a fastening device. The mounting device includes vertical anchors, symmetrically mounted on both sides of the rail 1 and made each in the form of a hollow cylinder 5, passed through the hole 4 in the bed 2. In the lower side surface of the hollow cylinder 5 there are vertically arranged diametral grooves 6. In contact with the upper surface of the cylinder 5 has an upper clamp 7 with a vertical hole 8 in the center, and the lower clamp 9 is pressed against the lower surface of the lying 2, in the middle part of which there is a semi-circular, located along the rail 1 An upward thickening with a horizontal hole 10 in the center for the passage and fixing of the flexible cable 11, the upper end of which is connected with the possibility of fixing with the upper clamp 7 through the bolt 12 with the nut 13, passed through the hole 8 in the clamp 7. 2 Il.

The invention refers to travel

railway transport and mainly to metro lines,

The purpose of the invention is to increase the efficiency of damping rail oscillations and to reduce the noise level during the passage of rolling stock.

FIG. 1 shows the upper structure of the path, a vertical cross section; in fig. 2 - the same „top view.

The upper structure of the track contains rails 1 with elements of intermediate and butt fastening, laid on lezhny 2, mounted on a rigid base 3 ways using a fastener |

The mounting device includes vertical anchors symmetrically located on both sides of the rail 1, each of which is designed as a hollow cylinder 5 passed through the hole 4 in the bed 2, the diametrically positioned diametrical grooves 6 are made in the lower part of the side surface, the upper clamp is 7 sec. vertical hole 8 in the center, which is installed in contact with the upper surface of the cylinder 5, and the lower clamp 9, pressed against the lower surface of the lying 2, in the middle part of which is located along the rail a 1 and a semicircular cross-sectional upward thickening with a horizontal hole 10 in the center for passage and fixation of an elastic element, which is made in the form of a flexible cable 11, the upper end of which is connected with the possibility of fixing to the upper clamp 7 through a threaded fastener 12 ( bolt) with nut 13, passed through the hole 8 in the clamp 7.

A leg 2, installed at the intended place of the path and provided with holes 4, is raised with jacks so that from below the bed 2 above the surface of the rigid base 3 of the path there is a space for free placement of the ends of the lower clamps 9., on which the leg 2 rests during operation one). The assembled hollow cylinders 5 are inserted into the holes 4 so that the lower clamps 9 do not interfere with the lowering of the hollow cylinders 5 into the holes 4 and then turn the back cylinder 5 so that

the lower clamps 9 were under the bed 2 (Fig. 2, the position of the hollow cylinder on the left). Rotating the nuts 13, tighten the flexible cables 11 up to the stop with the lower clamps 9 into the lower surface of the leg 2, then reach the leg 2 position (horizontal or inclined) set by the design and remove the jacks.

When the rolling stock is moving, the oscillations of the track are damped due to the elasticity of the flexible cables 11, which also leads to a weakening of the noise from the moving train.

The proposed design allows to increase the service life of the damping mechanism of the path compared to rubber gaskets. It is easier to adjust the bed position, i.e. ways, which is of great importance in the operation of the metro. In the event that a defective element appears in the proposed device, for example, after a long period of operation under severe conditions, the replacement of any element can be carried out very quickly without disassembling the track and using only jacks. Damping the oscillation of the path increases the service life of this path, and reducing the noise creates more comfortable conditions for the personnel and passengers of the metro.
