Description

TECHNICAL FIELD OF USEFUL MODEL

The utility model relates to the field of electrified transport and can be used in contact traction devices, namely, for load compensation devices for the tension of conductors and cables of power lines of contact networks of railways.

LEVEL OF TECHNOLOGY

Known compensatory weight made with a through fixing hole, symmetric with respect to the slot for the rod, while the fixing protrusion is made corresponding to the shape and size of the through hole with the possibility of mutual penetration of the fixing protrusion of one weight and fixing hole of the other weight when the latter is rotated by 180 degrees. (Description of the invention to the inventor's certificate No. 1736775, IPC В60М 1/26, published on 12/18/1989).

The disadvantage of this design is its complexity (it consists of two parts), high labor costs during installation and high cost.

Known compensatory load, which is a disc with a U-shaped slot in the middle with a square protrusion on one side and a square recess on the other side, characterized in that it is made of concrete with the addition of polypropylene fiber or with metal reinforcement. (Description of the utility model to the patent of the Russian Federation No. 134858, IPC B60L 1/00, published on November 27, 2013).

The disadvantages of this cargo include its relatively low volumetric weight and large dimensions, as well as a relatively low service life, depending on the frost resistance of concrete.

USEFUL MODEL DISCLOSURE

The task of the proposed technical solution is to eliminate these disadvantages.

The technical result of the task is aimed at improving the design of the compensating weight.

The solution to this problem is achieved by combining the use of a known feature, including a disc with a U-shaped slot in the middle, with a protrusion on one side and a recess on the other side; and new features, namely that the disc consists of a UV-stabilized polymer body filled with a composite composition based on polymers with weighting fractions.

The claimed utility model will make it possible to create a compensatory load that is reliable during operation, while it will have a low cost.

According to the conducted patent information research, the combination of known and new features of the proposed utility model was not found in the Sources of patent and scientific and technical information, which allows us to classify the feature as having novelty.

These features are essential and are interconnected with the formation of a stable set of essential features sufficient to obtain the required technical result.

The present utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

IMPLEMENTATION OF THE USEFUL MODEL

The essence of the compensatory load is that it consists of a disk with a U-shaped slot 1 in the middle, with a tapered protrusion 2 on one side and a tapered recess 3 on the other side, which, connecting in a "groove-comb" type, allow you to put on the required amount of weights on the cable , thereby providing the necessary cable tension force. In this case, the disk is made in the form of a UV-stabilized polymer body 4 filled with a composite composition based on polymers with weighting fractions

The advantages of the proposed technical solution are:

1. Reducing the cost of compensatory cargo;

2. Composite material, in contrast to concrete loads, is more resistant to vibration load, which increases the service life;

3. The structure is not hygroscopic (unlike concrete loads);

4. Smooth surface of the cargo body prevents coking from dirt and dust, adhesion of snow and ice

5. The manufacturing process is less energy consuming and more environmentally friendly;

6. Polymer material is easily recyclable (recyclable);

7. More aesthetic appearance;

8. Longer service life (as opposed to concrete);

9. Not of value to vandals and scrap metal collectors.

Currently, a pilot batch of compensatory cargo has been manufactured, which has been transferred for testing. The preliminary test results are positive.

Claims (1)

Compensating load containing a disc with a U-shaped slot in the middle, with a protrusion on one side and a recess on the other, characterized in that the disc consists of a UV-stabilized polymer body filled with a composite composition based on polymers with weighting fractions.
