Abstract

The cable drum relates to devices for winding, unwinding, storing and transporting cable products, as well as hoses, and can be used on mobile vehicles for use in electrical communication and power engineering. The purpose of the invention is the expansion of operational capabilities. The cable end connectors are inserted into the grooves of the console 8 located inside the drum neck, and then the cables are wound onto the drum. The minimum allowable bending radius of the cable is provided by the radius of the curved panel 7. 8 Il.

The invention relates to devices for winding, unwinding, storing and transporting cables as well as hoses, and can be used on mobile vehicles for use in electrical communication engineering, power engineering.

A cable drum structure is known, comprising cheeks, each of which is formed by a rim rigidly connected with spokes, with a sleeve installed in the center of the rim, a neck made in the form of circumferentially arranged rods and additional straight rods parallel to the axis of the drum from the last.

Each core of the drum neck is made in the middle of the U-shaped with curvilinear bends adjacent to the corresponding spokes, the spokes are made with holes in which the end sections of the said rods are installed and can be rotated relative to the axis of the holes with fixation in a predetermined position, with additional rods placed in the inner neck of the drum neck and fastened to the spokes.

A disadvantage of the known cable drum design is the absence of fixing elements for the end connectors of the finished cable line (cable), the lack of winding several cables of different diameters at the same time, as well as low processability due to the use of welding of the spokes to the rim and bushings, a significant metal intensity.

The aim of the invention is to enhance the operational capabilities of the cable reel.

The essence of the invention is that the placement of the cable end pieces is carried out inside the drum neck, which makes it possible to fully utilize the useful volume of the drum.

With the use of a console placed inside the drum neck, it is possible to wind several cables simultaneously, separately or connected into a tape, or hoses (up to ten sizes of cables on one drum, depending on the outer diameter of the cable).

Figure 1 shows a drum about a device for fixing cable end connectors; figure 2 is the same cross section; on fig.Z - section aa in figure 2; figure 4 - section bb in figure 2; figure 5, 6 - console; 7.8 - panel.

The araban contains cheeks 1, the rim 2 is rigidly fixed on the outer diameter, the shaft is made in the form of a tubular axis 3, disks 4 rigidly fixed on it along the edges and sleeves 5 pressed from both sides, a neck formed by tubular strums 6, a panel 7, which is located inside the neck of the drum and is screwed to the two rods, the console B fixed to the surface of the panel.

The rods b are flared in the holes of the cheeks 1. One of the rods is shifted to the center of the axis of the drum and down from the horizontal axis

0 to fasten on it the curved side of the panel 7, made along radius 9, adjusted to the minimum allowable bending radius of the cable. The flat side of the panel is attached to a rod located on the opposite side of the neck. The offset of the rod also provides access to the grooves of the console, in which the end elements of the cables are fixed.

The console 8 has in the upper part of the flange 10, located on both sides of the grooves. The height of the cantilever is determined by the end of the cable chains located in its slots.

Namogka cables on the drum is as follows

The free ends of the cables are inserted into the console gases corresponding to the external diameter of the cables. Due to the interaction of the end connector, the diameter of which is larger than the outer diameter of the cable and shoulder 10 in the upper part of the console, is fixed, after which

5 winding.

The proposed cable drum, in comparison with the known one, possesses wider operational capabilities.

0 In the drum there are elements of fixing the cable end connectors located inside the neck. Instead of a single cable placed on the drum, in the proposed drum it is possible to produce at the same time a coil of several cables differing in their outer diameter and different types of end elements (connectors). The cables placed on the drum are bent in the presence of winding

0 a smooth transition from panel to neck, the radius of which is equal to the minimum allowable bending radius of these cables, as a result of which the cables are highly reliable.

The proposed cable drum has a lower metal consumption due to the use of smooth tubular rods instead of rods made from rods, the drum device is simple and is technologically advanced.
