Description

The invention relates to electrical production, in particular to devices for connecting cables to the traction cable when laying cable routes on ships, and can be used in the electrical industry, communications industry and civil engineering.

The aim of the invention is to expand the scope of the end cable grip.

FIG. 1 shows the cable end gripper in the working position, general view; in fig. 2 - the same, longitudinal section; in fig. 3 - adapter, cross section along the conical tip; in fig. 4 - the same, on a loop of a groove of a clip.

End cable grip (figure 1) consists of an adapter (tip) 1, having a section of cylindrical shape, equipped with a loop-like groove 2 for storing traction cable 3, a conical tip 4 and a tube 5 of metal mesh for connection with cable 6.

The adapter 1 is made in the shape of a bullet (Fig. 2). The clamp for the cable is a through groove 2, having the form of a closed loop and located along the side surface of the adapter 1. The inlet opening of the groove is located along the longitudinal axis of the adapter on the end of the last, and the output on the side surface at the base. At the base of the adapter 1 there is an annular protrusion '7 with uniformly spaced circumferentially through holes 8, into which the thin cables are passed. Of the cables, a knotless connection between the cells, woven metal mesh 5, having the shape of a tube. In the frontal part of the tip 1 is a cylindrical protrusion 9 for mounting the conical tip 4. The conical tip 4 is made in the form of a sleeve with a through longitudinal groove 10 for passing the cable 3, the central hole 11 for mounting on the protrusion 9 of the adapter 1 and a rectangular protrusion 12 located opposite the groove 10 on the inner surface of the sleeve overlapping the groove 2 of the adapter, as a result of the exclusion of the rotation of the tip 4 relative to the re 10

hub propeller 1, and consequently, the fallout of the cable from the groove.

End cable grip works as follows.

Metal mesh 5 when pressed on the free end along the axis of the accordion to the base of the adapter. The end of the cable 6 is inserted into the inside of the grid 5 until it touches the end of the adapter base, and the grid 5 extends back along the cable 6.

To attach the end cable grip to the continuous traction cable, the cable 3 is loosened and folded with at least one loop and stored in the loop groove 2 of the tip 1. Conical tip 4 is guided through the groove 10 from the cylindrical protrusion 10 so that its protrusion 12 faces against the entrance to the groove 2 adapter 1, and put on the tapered tip 4 on the cylindrical protrusion 9.

At the free end of the grid 5 and the portion of the cable 3 passing over it,. impose a common band 13 (Fig. 1) of 2-3 turns of soft wire, which creates at this end of the cable a small initial holding force required for the initial tightening of the loops of the cable 3 located in the groove 2 around the protrusion 14 (Fig. 2).

Connecting the end of the cable grip to the end of the traction cable

produced as described with the difference that the end of the cable 15 ends behind the bandage 13, as shown in FIG. 1 dotted line.

40 Detachment of the grip from the traction cable is performed by loosening the cable in the reverse order.

The proposed end cable grip is universal and can be used as part of all conveyors for pulling cables made according to any technological scheme of puffing; cable end, continuous cable and cable rewindable from drive to drive. This ensures a smooth entrance of the cable end to any type of roller bearings that make up the conveyor, which reduces cable pulling forces, reduces the power and dimensions of the conveyor drives by an average of 10-15%. Capture

can be used on cable routes

any configuration.
