Description

The utility model relates to the upper structure of a railway track and is intended for fastening rails to the base, for example, to railway sleepers.

Known devices for fastening rails to wooden, reinforced concrete sleepers [1] or to steel substrates [2], directly [3] or through gaskets [4], metal consuming, require significant labor costs for repair and maintenance of the upper structure of the railway track, provide insufficient throughput ability of the way.

The closest to the proposed utility model in terms of the set of features and the technical result achieved is the rail fastening of the Pendrol Limited company (Great Britain) [5].

The known device contains a rigidly fixed anchor on the base (sleepers), in the upper part closest to the rail a portion of which is made parallel to the rail with a horizontal hole with a circular cross section. The central leg of the G-shaped steel spring terminal is inserted into this hole. The middle part of the spring terminal rests on a horizontal section of the peripheral part of the anchor farthest from the rail, and the terminal part or the clamping part interacts with the upper part of the rail sole directly or through the gasket.

The asymmetric load on the spring terminal of the known device from the vibrating rail does not exclude the possibility of spontaneous exit of the terminal legs from the holes in the anchor. To prevent such a displacement, the introduction of a locking unit is required, for example, the implementation of engaging protrusions on the mating sections of the spring terminal and the horizontal anchor platform. The known device is laborious to manufacture and requires significant labor costs during installation and dismantling of the upper structure of the railway track.

The proposed utility model is based on the task of creating a rail mount that would have a simplified design, reliable in operation and providing reduced labor costs for installation and dismantling.

The problem is solved in that in the rail mount containing the anchor, rigidly fixed to the base, for example, a railway sleeper, in which there are two seats in the form of grooves for the legs of the spring terminal, according to the utility model, one of the seats is made in the head of the anchor open along its entire length with the height of the open part exceeding the maximum vertical linear dimension of the cross section of the legs of the spring terminal, and the anchor riser has at least two stiffeners.

The second seat in the head of the anchor can be made open along the entire length, and the height of its open part is less than the maximum vertical linear

cross-sectional dimension of the conjugated leg of the spring terminal.

The second seat in the head of the anchor can also be made with a round cross-section, the size of which allows the free introduction of the legs of the spring terminal along the axis of the hole.

The spring terminal may have a cross section other than round, the maximum linear dimension of this section being oriented vertically.

A thrust comb may be provided in the anchor.

In the riser of the anchor can be made holes filled with a binder material, for example, concrete.

The rail, anchor and the clamping part of the spring terminal are made with the possibility of interaction through the liner.

The symmetrical load on the spring terminal from the vibrating rail eliminates the possibility of the spring terminal leg coming out of the grooves of the anchor head. At the same time, a fixing unit is not required to prevent the displacement of the spring terminal leg.

To simplify the manufacturing technology of the anchor, for example, when stamping it, and to reduce the metal consumption, the longitudinal grooves in the head of the anchor can be made in the form of a recess open along the entire length (in the form of a part of a rotation body truncated along its axis), while the height of the open part of the recess must be smaller than the diameter of the spring-loaded terminal block with a circular cross-section or the maximum linear cross-sectional dimension if different from round.

This shape of the groove eliminates the possibility of the outside of the legs of the spring terminal being brought into it in a direction that does not coincide with the axis of the groove, i.e. provides convenience and safety of installation and dismantling works.

The presence of stiffeners and a persistent ridge, perceiving radial loads, provides reliable fastening of the anchor to the base of the railway sleepers.

The implementation of the anchor riser holes filled with a binder material, such as concrete, helps to reduce the metal consumption.

The execution of the rail, anchor and the clamping part of the spring terminal with the possibility of interaction through the liner contributes to additional fixation of the rail relative to the anchor. The liner, together with an elastic gasket, dampens noise and vibration during operation of the railway track.

The essence of the utility model is illustrated by drawings.

The rail mount for attaching the rail 1 to the base, for example, to the railway sleepers 2, contains an anchor 3, rigidly fixed to the base, for example, by monoling, screwing, welding. From different sides from the axis of the anchor 3 in its head made seats - grooves 4 and 5 in the direction perpendicular to the axis of the rail 1.

Terminal 6 is made of mild steel in the form of a C-shaped double loop, the lower free ends of which are brought into groove 4 and groove 5.

The groove 4 can be made with a round cross-section, the size of which allows the free introduction of the legs of the spring terminal 6 along the axis of the hole (Figure 3).

The groove 4 in the anchor can be made in the form of a recess open along the entire length (Figure 5, Figure 8, Figure 10). At the same time, the height In the open part should be less than the maximum double size of the cross section of the rod of the outer terminal 6.

The upper part of the spring terminal 6 in the mounted state rests on the upper surface of the rail 1 directly or through an insulating insert 7, mainly non-metallic, additionally fixing the position of the rail 1 relative to the anchor 3 and together with the elastic gasket 8 between the rail 1 and the sleeper 2, which dampens noise and vibration during operation the way.

The offset of the insert 7 relative to the rail 1 is prevented by its protrusions brought into the gap 9 between the rail 1 and the anchor 3 in the groove 10 of the open form (Fig. 8) or closed (Fig. 10).

Anchor 3 may have a thrust ridge 11 (Fig.9), which perceives radial loads.

At least two stiffeners 12 are made in the anchor 3. They can also be made to reduce the metal consumption of the hole 13 (Fig. 8) of arbitrary shape, filled with a binder material, for example concrete.

Rail mount works as follows.

To attach the rail 1 to the base, the anchor 3 is fastened to the concrete sleepers 2. The spring clamp leg is inserted into the groove 4, while the cross section of the groove 4 allows the spring clamp leg to be freely inserted along the groove 4.

In the groove 5 in the form of a recess, the leg of the terminal 6 can only be brought in with

lever device by turning the terminal around the hole 4, therefore, the height And the open part of the groove 5 must exceed the maximum linear cross-sectional dimension of the rod of the terminal 6.

The spring terminal 6, one of the legs of which is inserted into the groove 4 of the head of the anchor 3, has the ability to rotate about its axis. When mounting the path, the second leg of the spring terminal 6 can be inserted (or withdrawn) into the groove 5 on the opposite side of the head of the anchor 3. The upper part of the spring terminal 6 presses the rail 1 to the base of the railway sleepers 2. To reduce vibration loads between the rail 1 and railway sleepers 2, as well as between the spring terminal 6 and the sole of the rail 1, elastic gaskets, for example high-pressure polyethylene, are installed.
