The invention relates to lifting and transport machinery, namely, devices for supplying energy to a moving object. $

The purpose of the invention is expansion. functionality by “using on crane lifting ropes.

1 shows a schematic diagram of a ιθ device, a general view; figure 2 -. energy carrier layout.

A device for supplying energy to a receiver moved by a lifting mechanism, for example to a working one, 5 to a receiver's body 1, hung on a cargo rope 2 of a crane and operating in a well, contains a drum 3 mounted on axis A, on which a holder 5 is placed with 20 placed on it on both sides of the drum blocks 6. The rope 2 is movably connected with the drum 3, and the holder 5 is hung on the crane and connected by elastic ties 7 to two carriers 8, which are 25

with the possibility of rotation placed on the axis 4 on both sides of the yoke 5 and made with installed at their ends additional blocks 9.

The flexible energy carrier 10 is connected at its ends with the receiver 1 and the crane, and the middle section is placed inside the drum 3 in the form of an 8-shaped loop and is wound on it in opposite directions by branches 11 and 12, which are further laid in the vice policy , pastes 13 and 14 in each pair of blocks 6 and 9. At the same time, the polypast 13 formed by the branch 11 connected to the crane is made with a capacity equal to dd of the capacity of this branch on the drum 3 according to the maximum number of its revolutions, and the polyspast 14 formed by the branch 12 connected to the receiver 1, is made of a capacity sufficient only, to compensate for the discrepancy between the magnitude of the linear displacement of the rope 2 and the branch 12, which, like the branch 11, is wound on the drum 3 in the roll, but separated from it by a partition. Elastic bonds 7 are made with stiffness ensuring sufficient tension of the energy carrier 10 in the chain wheels 13 and

14 regardless of their capacity with a force not exceeding the maximum allowable tensile force for the type of energy source used.

A device for the supply of energy to the receiver, moving load-lifting2 4

mechanism works as follows.

In the initial state of the device, the receiver 1 is raised on the rope 2, for example, to the upper position, the drum 3 is maximally filled with the turns of the energy carrier 10, the blocks 6 and 9 of the polyspast 13 are minimally separated from each other, and the block 9 of the polyspast 14 is in a position that allows changing the distance between him and block 6 of this pulley depending on the direction of movement of the rope 2 and changes in connection with the diameter of the winding 12 on the drum 3.

When lowering the receiver 1 with the load-lifting mechanism into the well, the rope 2_turns the drum 3, winding the branches 11 and 12 of the energy carrier 10 from it. The free length of the branch 11 under the action of the elastic coupling 7 is assembled into the polyspast '13, and the branch 12 under the action of its own weight moves after the receiver 1 In the case of the formation of the free length of the branch 12. this length of the energy carrier is collected in a chain hoist _; 14 under the action of the elastic / connection 7, and the increase in the tension of the branch 12 is compensated by the reserve of the length of the energy carrier of this chain hoist. In the lower position of the receiver 1, the energy carrier 10 is wound from the drum 3, placed with its branch 11 in the polyspast 13, the blocks of which are as far as possible from each other, and the branch 12 is located along the rope 2 and part of the length in the polyspast .14, When the receiver 1 is raised, the device works in reverse order.

The polyspast 14, being a compensator for the length of the branch 12 of the energy carrier 10, simultaneously serves as an element of the dynamic unloading of the energy carrier.
