Description

The utility model relates to the field of electrical engineering, namely to the structures of cable drums designed for winding, transporting and storing long flexible products, such as cables and wires.

A cable reel is a coil that allows you to wind, store, transport and lay the cable when performing installation work when laying power lines and communication lines.

The most common type of cable drums is a wooden product. This is a simple cable container, often used for transporting, storing and installing cables. The drum consists of cheeks, a neck, tie rods, a packing sheath, a sleeve, a neck circle, a driver hole and a hole for a cable outlet. The production of wooden cable drums is carried out in accordance with GOST of 1979. In the production of wooden cable drums, boards of coniferous and hardwood are used.

The disadvantages of wooden cable drums are:

- loss of structural strength under the influence of the external environment, due to the use of natural wood;

- susceptibility to infection of wooden cable containers by fungus, mold and wood parasites;

- low manufacturability and lack of repeatability of products;

- complexity during transportation and subsequent assembly; excessive weight of the product, due to the production technology of cable drums from solid boards;

- increased fire hazard during storage.

The use of plastic or plywood cable drums is possible when storing and transporting cables and wires of small size and mass, which is due to the low strength characteristics of these types of cable drums.

The most durable and strong cable reel is a metal cable reel, however, its use requires the use of an anti-corrosion coating, besides, it has a large dead weight and high cost.

Known patents, which describe the implementation of coils for electrical cables, containing a housing having a cylindrical part, on both sides of which are the sides (cheeks). See RU 2103217 C1, RU 48945, RU 2003102128 A1.

The disadvantage of these drums is their high material consumption and design complexity.

The objective of the utility model is to create a lightweight drum design that provides high quality winding of a long product, while ensuring high structural strength, manufacturability and improved performance of the drum itself.

The technical result is achieved by the fact that the drum for storing and transporting flexible long products contains a neck, cheeks, tie rods, a sleeve. What is new is that it is made of a composite material with the addition of a biological filler of plant origin, on the outside of the cheek there is a circular protrusion and symmetrical recesses, on the inside of the cheek there is a circular groove and protrusion, the neck of the drum is made in the form of a cylindrical part formed by a set of rails , on the inside of which grooves are made.

The recesses made on the outer side of the cheeks lead to a lighter design while maintaining the strength characteristics.

The circular protrusion on the outside of the cheek, together with the groove on the inside of the cheek, provides stacking grip, which makes it easier to store and transport the cheeks without additional fastening.

The presence of a protrusion on the outer side of the cheek of the drum reduces the likelihood of damage to the output end of the cable during storage or transportation of cable drums in a row "cheek to cheek".

The presence of a groove on the inner side of the cheek provides ease of assembly and a guarantee of the cylindrical shape of the neck, and an additional protrusion provides increased rigidity of the neck of the drum at the place where the rails are attached to the cheek.

The presence of additional cavities and recesses on the inner side of the neck rails of the cable drum provides additional weight savings of the product while maintaining the overall strength characteristics.

Such an implementation provides lightening and simplifying the design, increasing structural strength, and improving the performance of the product. The use of a composite material with the addition of a filler of plant origin provides lighter construction while maintaining strength characteristics and simplifies the drum assembly technology.

In FIG. 1 of the attached drawings shows a general view of the inventive drum for fastening and transporting long products in terms of%;

in fig. 2 - the same, longitudinal section;

in fig. 3 - drum cheek;

in fig. 4 - the same, side view in section;

in fig. 5 - view A in Fig. four;

in fig. 6 - cheeks are shown during storage, cross section.

The drum for fastening and transporting long products contains cheeks 1 with a sleeve 2 pressed into them, a drum neck made up of a set of rails 3. To ensure adhesion during stacking, a circular protrusion 4 is made on the outer side of the drum cheeks, and a corresponding circular groove is made on the inside 5 (FIG. 5). To increase the rigidity of the drum at the point where the rails 3 are attached to the cheek, an additional protrusion 6 is made. Outside of the filling end of the cable in the cheek, an outlet 10 is made. To save weight while maintaining the strength characteristics, recesses 11 are made on the outer side of the cheeks 1.

The assembly of the drum is carried out as follows.

Cheeks 1 are fixed vertically towards each other with the inner side at a distance slightly greater than the length of the rail 3 of the neck of the drum and then preliminarily tightened with tightening pins 8. The rails 3 are inserted into the circular groove 5 based on the protrusion 4, after the neck of the drum is fully assembled to the cylindrical shape of the cheek 3 with tie rods. pins 8 are pulled together until fully secured.

The winding of the drum is carried out as follows. The drum is fixed in the winding device by means of cone-shaped holders inserted into the sleeve 2, the drive of the winding machine is fixed in the hole 9. The charging end of the cable through the output hole 10 is brought out of the drum and fixed on the cheek 1.

Due to this design, the winding is carried out evenly, in even rows, which improves the quality of the cable winding.
