Description

The invention relates to the construction of railways, relates to the upper structure of the track, namely the attachment of rails to sleepers,

The purpose of the invention is to increase efficiency by creating an additional effort to press the rail against the base.

Figure 1 shows the rail fastening; figure 2 - additional two shoulders lever, front view; on fig.Z - the same, top view; figure 4 is the same, side view; figure 5 - anchor element, front view; figure 6 is the same, side view; in Fig.7 - the axis of the anchor element, front view; FIG. 8 is the same, top view; figure 9 - terminal, front view; in fig. 10 is the same, top view; in fig. 11, too, side view; on Fig - spring, front view; in fig. 13 - the same, side view.

Rail fastening is arranged as follows.

The anchor element 1 is lowered into the hole in the sleeper until it stops. The anchor element 1 rotates clockwise so that its claws engage with the locking grooves of the insulating sleeve 2. Next, an insulating sleeve is inserted into the hole in the sleeper, consisting of two parts 3 and 4. After their installation, the anchor element

It is in a strictly fixed position. Next, the elastic gasket 5 is installed and the additional two-arm lever 6 is installed, the position of which is fixed by the axis 7 passing through the hole of the anchor element 1 and through the additional two-arm lever hole 6. After the additional two-arm lever 6 is fixed, the rail 8 is laid and the installation of terminal 9, Terminal 9 with cut-out a fits onto the mounted axis 7 and by pushing it engages cut-out b with the axis 7.

The final installation of the fastener is to install the spring 10 and the wedge 11. This is done by inserting the end of the spring 10 under the additional double-arm lever 6. The spring 10 with its body goes into the fixing notches of the axis 7. Wedge

I1 is supplied under the supporting part of the additional two-arm lever 6 and is brought into contact with the spring 10. The wedge 11 is spring-loaded in the transverse direction and is equipped with a shock absorber 12.

Bond installation is done. Fixing the rail to the sleeper occurs under the action of the energy generated by the rolling stock.

Rail connection works as follows.

The wheel of the train, rolling on the place of fixation, the weight of the train and its weight

acting on the rail 8 and the gasket 5. The rail 8 under the action of the force of the body of the train is lowered by the amount of deformation of the gasket 5. At the same time, the rail bottom 8

acts on the end of the additional two-arm lever 6, the latter is made in the form of a regular circle, collapsing under the action of the rail foot 8 and rotating on the axis 7 with the opposite working end acting on one of the arms of terminal 9.

Thus, under the action of an additional two-arm lever 6, terminal 9 receives a rotational movement around axis 7. The other shoulder of terminal 9 has an eccentric surface and, rotating around the circumference, the radius of the surface of the shoulder of terminal 9 gradually increases, thereby increasing the force of the impact of the shoulder of terminal 9 on the sole rail 8. Ascending

the force is proportional to the increase in the radius of the eccentric surface of the shoulder terminal 9.

Taking into account the elastic properties of the shock absorber, you can create an additional pressing of the rail foot to the sleeper within very large limits. The spring 10 due to its elastic properties actuates the wedge 11, and the latter fixes the position of all fastening parts in the working (fixed) state after the passage of the rolling stock,

An additional pressure on the rail foot is also directly proportional to the weight of the train.

Rail 8 is fixed. Uncoupling

performed by removing the wedge 11 from the shoulder of the additional two shoulders lever 6.
