Description

Fret anchor

Technical field

The split sleeper anchor serves to increase the resistance of the sleeper in the rail box of the railways to the lateral displacement.

BACKGROUND OF THE INVENTION

The products of the German companies Vossloh-Werke GmbH, Werdohl, BRD and Heinrich Paulus, Aachen, BRD are mainly used as sleeper anchors.

Vossloh manufactures a single blade type and a double blade type, long, which is designed for quick assembly without disturbing the corroded track bed under the sleeper bed. These types of sleeper anchors can also be mounted on the head in the middle of the sleeper. The fastening of the tie-rod yoke and the blades is carried out by one resp. two connecting bolts with nut.

Heinrich Paulus products are single-blade, non-cut, equipped with four yoke bolts and sleeper anchor blades. These sleeper anchors can only be mounted on sleeper heads.

None of the above-mentioned products to ô is not universally used Other for shape and size reasons ô for all types of types. sleepers and concrete sleepers. According to Vossloh, the design types of sleeper anchors do not show! in addition, the required fastening strength is fixed to the sleeper. This is mainly due to the shape of the yoke anchor of the sleeper anchor and from the point of view of the sleeper anchor.

Heinrich Paulus products show! the required fastening strength on the sleeper, but their mounting is complicated in the grate mounted in the ballast bed, as they are fastened by four screws ε ». it is necessary to rake the sleeper during assembly. The biggest disadvantage of Heinrich Paulus products is the fact that they can only be mounted on the heads of the machines because of the design

It is also one of the following examples. It is used for all types of sloping sleepers.

SUMMARY OF THE INVENTION

These drawbacks are overcome by the fret anchor according to the invention, which is based on a new structural design of a fret anchor, which is made of steel material and consists of a yoke and split vanes. The sleeper anchor blades are attached to the yoke by two bolts that are attached to the blades. Long blades allow! easy installation without disturbing the consolidated rail bed layer under the work surface.

The caliper of the sleeper anchor is shaped according to the cross section, the sleeper to prevent its spatial displacement on the sleeper.

The novelty of the solutions consists in the use of the clamp effect when tightening the yoke and the ties of the fret anchor by resting the yoke seat on the rim of the vane, with the paddle flat against the yoke ensuring optimum grip.

The low bending stiffness of the connecting bolt in the lateral direction allows it to be easily rolled over during assembly so that the perpendicularity of the bolt with respect to the shaped yoke is guaranteed on both sides at the place of the flat washer on the oval opening.

Said type of sleeper anchor exhibits the required fastening strength on the sleeper in a simple assembly, since no mechanization means are required and with minimum maintenance requirements.

The split anchor is usable for all types of sleepers used in ČSD by adapting the shaped yoke to the required sleeper dimensions.

A method for practicing the invention

Phase anchors are useful for establishing a seamless rail in curves of a small half-track of railways, welded switches and crossings, and in justified cases where the stability of the seamless rail could be impaired.
