SK278416B6 - The putlog anchor divided - Google Patents

Abstract

The putlog anchor divided for mounting to putlogs (1) of railways, used for increasing of the resistance against a transversal moving in the railway bed, is created with the use of the strap (2) a shape of which is accommodated to the transversal cross-section closed to putlog (1) and with two flat shoulders (11), chamferred to one side towards the putlog (1) vertically. After the shoulders (11) had been set to the putlog (1) and a position of them was determined by the retainer (13), and they were connected with the use of the screws (6), with the strap (2) surrounding the putlog (1) from above and sides, the grip closing of the putlog (1) is created, after the tightening of the nuts (9), and the fixed connection of the putlog anchor with the putlog (1), as a result of that.

Description

Technical field

The split anchor is used to increase the resistance of the sleeper in the rail bed against the lateral displacement.

BACKGROUND OF THE INVENTION

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

Vossloh manufactures a single blade type and a double blade type, split, which is designed for rapid assembly without disturbing the consolidated bedding under the sleeper bed. These types of sleeper anchors can be mounted on the head even in the middle part of the sleeper. The fastening of the anchor caliper and the blades to each other is effected by one or two connecting screws with a nut, respectively.

Heinrich Paulus products are single-blade, undivided, equipped with four caliper connecting bolts and paddle anchor blades. These sleeper anchors can only be mounted on the sleeper heads.

None of the above-mentioned products is universally applicable for all types of timber and concrete sleepers for shape and size reasons. According to Vossloh, the construction types of sleeper anchors do not show the required fastening strength on the sleeper. This is mainly due to the shape of the caliper of the sleeper anchor and the way of screw fastening.

Heinrich Paulus products have the required fastening strength on the sleeper, but their installation is complicated when the grate is embedded in a gravel bed because they are fastened with four screws and the sleeper must be underfoot during installation. The biggest drawback of Heinrich Paulus products is that they can only be mounted on sleeper heads because the design of the blades does not allow any other way of attachment. Their use is therefore excluded for all types of sleepers with inclined ends.

SUMMARY OF THE INVENTION

These drawbacks are overcome by the low-profile anchor divided according to the invention, which is based on a new construction of the low-level anchor, which is made of steel material and consists of a caliper and split blades. The bucket anchor blades are connected to the caliper by two screws that are attached to the blades. The split vanes allow easy mounting without disturbing the consolidated bed bed under the sleeper bed area.

The caliper of the sleeper anchor is shaped according to the transverse profile of the sleeper to prevent its spatial displacement on the sleeper.

The novelty of the solution lies in the use of a tick effect when tightening the caliper and the bucket anchor blade by engaging the caliper mounting surface on the blade rim when the paddle pressing surface acts against the caliper, ensuring its optimal holding ability.

The low bending stiffness of the connecting bolt in the lateral direction allows it to easily bend during assembly so that the perpendicularity of the bolt with respect to the shaped bracket is guaranteed on both sides at the point where the flat washer rests on the oval opening.

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

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

Overview of the figures in the drawing

An exemplary embodiment of a sleeper anchor is shown in the accompanying drawing. 1 is a basic elevational view of a sleeper anchor divided into a sleeper embedded in a track, FIG. 2 is a side view and FIG. 3 is a plan view of a fastening of a sleeper anchor divided into a sleeper.

DETAILED DESCRIPTION OF THE INVENTION

The split anchor placed on the sleeper 1 consists of a shaped yoke 2 equipped with two bearing plates 3, side guides 4 and two oval holes 5 into which two screws 6 are inserted.

A flat washer 7, a spring washer 8 and two nuts 9 are mounted on each bolt 6. The bolt 6 is formed at its bottom by a flat shaft 10.

The split anchor is further comprised of two identical plate-shaped blades 11. The plate-shaped blade 11 has a flat rim 12 formed in the upper part to which a flat shaft 10 is attached. On the flat rim 12 a stop 13 and a pressure surface 14 are further formed.

Industrial usability

The sleeper anchors are useful for establishing a seamless rail in curves of small track radius, for welded switches and crossings and in justified cases where stability of the seamless rail could be impaired.
