Abstract

SUMMARY OF THE INVENTION: A cable or hose is placed between the branches of a cargo rope, fastened to the movable branch of the cargo rope by freely sliding rings and rigidly in the upper part of the fixed branch. The device is equipped with a basket for laying a cable or hose fixed above the block and has openings for passage of branches in the bottom part. 3 ill.

Description

The invention relates to electrical engineering, in particular to flexible current-carrying devices for mechanisms having vertical movement, and can be used in workshops of industrial enterprises equipped with bridge cranes, hoists and similar hoisting mechanisms when hanging electromagnets, suction cups, manipulators, etc. P.

The purpose of the invention is to simplify the design and expand technological capabilities by placing a flexible energy carrier between the branches of the freight rope with fixing sections of its bend on the movable branch using freely sliding rings, as well as the presence of a basket for laying a flexible energy carrier, fixed in the upper part of the fixed branch of the rope .

The goal is achieved using the following design differences:

1) a flexible energy carrier is rigidly fixed in the upper part of the fixed branch of the rope;

, 2) a flexible energy carrier is placed between the branches of the cargo rope, the remaining sections of its bend are fixed to the movable branch of the cargo rope by means of freely sliding rings;

3) the device is equipped with a flexible energy carrier stacking basket fixedly mounted above the block and having openings in the bottom of the passage for the passage of the branches of the cargo rope.

In Fig .1 is a diagram of the proposed device; in FIG. 2 is a view A in FIG. 1; in FIG. 3 is a view B of FIG. 1.

The drawings show a diagram of the proposed device for a particular case.

The device for supplying energy to a controlled load-gripping body of the lifting mechanism consists of a flexible energy carrier (cable) 1, rings 2 and 3, one of which 2 (closest to the lifting mechanism) is rigidly fixed in the upper part of the fixed branch of the cargo rope 4, and the rings 3 freely cover fixed 4 and movable 5 branches of the cargo rope. A basket 7 for cable laying is rigidly mounted on the hook suspension b, consisting of two half-disks 8 and 9 with openings 10 for passing the branches of the cargo cable 4 and 5.

The device operates as follows. When lifting the load of the hook, the suspension 6 together with the basket 7 moves upward, the tension of the lower sections of the cable 1 located between the rings 3, subsequently. It weakens completely, rings 3 slide along branches 4 and 5, and the cable is looped into basket 7, because the cable length is less than l D / 2 received between adjacent rings, where D is the distance between the branches of the rope, while the cargo branches of the rope pass through holes 10 of two half-disks 8. and 9,. . . .-. . . ..;

The device has the following advantages compared to the prototype:

- simplification of structures due to the absence of additional devices for hanging the cable;

- expansion of technological capabilities, as can be used for electromagnet current supply cable, for vacuum suction hose and the like.

Expected economic efficiency is 3 thousand rubles.

A sketch design has been developed for the proposed device. To ensure the use of the device in industrial conditions, it is planned to develop drawings, manufacture and test the device (in 1992) at the Dnepropetrovsk Metallurgical Equipment Plant.

Claims (1)

The claims A device for supplying energy to a controlled load gripping body of a load-lifting mechanism, comprising a cargo rope stored with the formation of two branches covering the block, one of which is fixed rigidly, and the other is wound on a drum, a flexible energy carrier laid in a zigzag pattern, some of which additional means of supporting the energy carrier are distinguished by the fact that, in order to simplify the structures while expanding the operational capabilities, a flexible energy carrier is placed between the branches of the cargo rope, the remaining sections of its bend are fixed to the movable cargo rope by means of additional rings forming the indicated support means and is also installed claimed freely slidable, the device being provided with a flexible energy carrier laying basket, fixedly mounted above the block and having openings in the bottom of the passage for the passage of the branches of the cargo rope, while the flexible energy carrier is rigidly fixed to top of the fixed branch of the rope.
