Description

The utility model relates to the construction of railways, namely to the device of the upper track structure, and can be used for fastening rails to sleepers.

A means is known for fastening rails to sleepers (see the Great Soviet Encyclopedia, second edition, vol. 36, p. 344, M., BSE State Scientific Publishing House, 1955).

The known means for fastening is made in the form of crutches, which are hammered into the sleepers and hold the rails with their hats.

Such fastening can be used only for wooden sleepers.

Also known is the terminal for fastening rails to the liners, made in the form of a plate of adjacent and clamping parts with an aperture for fastening means in the adjacent part (see GOST 24741-81. The site for mounting crane rails to steel crane beams. Technical conditions).

This technical solution is the closest to the claimed combination of essential features (prototype).

The terminal regulated by GOST ensures the fastening of the rails to the linings installed on more modern reinforced concrete sleepers equipped with fastening means.

However, the known terminal is a straight plate. In this case, the rigidity of fastening the rails to the liners depends on the tightening force of the nuts of the fastening bolts and the properties of the material from which it is made. At the same time, during operation under the influence of alternating loads and temperature extremes, a permanent deformation occurs in the terminal after a certain period of time and for this reason the fastening loosens. To prevent this situation, constant monitoring of the condition of the fastener, timely tightening of the nuts of the fastening bolts and frequent replacement of the terminals is necessary.

The objective of this utility model is to create such a terminal for attaching rails to pads, which would improve the reliability of fastening and reduce the time for preventive maintenance.

To solve the problem, at the terminal of fastening the rails to the linings, made in the form of a plate of adjacent and clamping parts with an aperture for fastening means in the adjacent part, according to a utility model, the terminal further comprises a removable cover plate, the clamping part of the plate is made in the form of an open loop with a smooth transition to the adjacent part, and the removable pad is provided with a bent part that repeats the profile of the plate at the transition from the adjacent part to the pressure.

The execution of the clamping part of the plate in the form of an open loop with a smooth transition to the adjacent part increases the elasticity of the terminal and its resistance to alternating loads and temperature extremes.

The presence of a removable lining with a bent part, repeating the profile of the plate at the transition from the adjacent part to the clamp, increases the stiffness and elasticity of the terminal in the specified place, the most exposed to stress.

Thus, the proposed measures can improve the elastic and strength properties of the terminal, and thereby increase the reliability of the rails fastening to the linings and reduce the time for preventive maintenance.

In the future, the utility model is illustrated by a description of specific options for its implementation and the accompanying drawings, in which:

Figure 1 - terminal mounting rails to the pads, General view;

Figure 2 - terminal without a removable lining;

Figure 3 is the same, a top view;

Figure 4 - removable pad;

Figure 5 is the same, a top view;

6 is a removable pad with a persistent collar;

Fig.7 is the same top view.

The terminal of fastening the rails to the pads (Figs. 1, 2, 3) is made in the form of a plate (1) of equal thickness from the adjacent (2) and pressing (3) parts with an opening (4) for fastening means (5) in the adjacent (2) parts. The clamping (3) part of the plate (1) is made in the form of an open loop with a smooth transition (6) to the adjacent part (2).

The terminal also contains (Fig. 4, 5) a removable cover plate (7) with a bent part (8), the profile of which repeats the profile of the plate (1) of the terminal at the place (6) of the transition from the adjacent part (2) to the pressure part (3).

The fastening means (5) are a bolt (hairpin) fixed in the lining or sleepers, equipped with a nut and washer.

The removable pad (7) may be provided with a collar bent down (9) (Fig.6, 7).

The terminal plate (1) is installed with an aperture (4) on the bolt of the fastening means (5) located in the lining fixed to the tie, or in the body of the tie, until its contact part (2) contacts the lining, and the pressure part (3) to the sole surface rail pre-installed on the lining, which in turn is installed on the railroad tie. After that, the removable cover (7) is laid on the plate from above (1) and the nut of the fastening means (5) is tightened through the washer. This creates a force that causes elastic deformation in the clamping part (3), the smooth transition (6) and the bent part (8) of the lining (7).

Due to this, conditions are provided under which alternating loads arising during subsequent operation, as well as significant fluctuations in the ambient temperature for a long time, do not cause weakening of the fastening.

When using the trim (7) with the shoulder (9), the latter bends around the outer edge of the lining and prevents the possibility of turning the trim (7) around the axis.

Thus, the implementation of the clamping part of the plate in the form of an open loop with a smooth transition to the adjacent part and the presence of a removable lining with a bent part that repeats the profile of the plate at the point of transition from the adjacent part to the clamp, allows to increase the elastic and strength properties of the terminal, and thereby increase the reliability fastening rails to linings and reduce the time for preventative maintenance.
