Abstract

SUMMARY OF THE INVENTION: the device comprises a drive, an axis, on which a winding drum is mounted in the form of rigidly interconnected discs with rollers and flexible guiding circuits surrounding them. Under the peripheral sections on the disk, a current collector is installed, to which a cable is connected at one end ;. The axis is threaded and provided with a nut kinematically connected with flexible contours. Such a design improves the durability and operational reliability of the cable. 1 C.p. f-ls, 1 ill.

Description

with

The invention relates to electrical engineering, in particular to devices for supplying electricity from a fixed source to a moving source, to a consumer, for example, self-propelled hoisting-and-transport, construction, bridge and other machines and mechanisms with electric drives of working bodies.

An object of the invention is to increase operational reliability by providing for winding and unwinding cables from the end of the drum.

This goal is achieved in that in a device for supplying power to a moving object, comprising a winding drum with end disks mounted on an axis with supports and a neck for cable laying, one end of which is connected to a current collector and the other end to a power source, a drum drive and tools for orderly styling

cable, including a nut mounted for rotation on the threaded shaft, the neck of the drum is formed by infinite flexible contours, each of which covers rollers freely mounted on the disks, the axis of the drum is made integrally with the threaded shaft, the nut is kinematically connected to one of the branches of each a flexible contour, with the cable part of the length located with a margin inside the neck of the drum and mounted on a nut; in order to maintain a constant working: diameter of the neck of the drum, the device is equipped with guides installed with the possibility of interaction with them of the peripheral branches of the flexible circuits.

The invention is illustrated in the drawing, which is a cross-sectional view of a device for supplying power to a moving object.

A device for supplying power to a moving object comprises a drive 1, axis 2, on which a winding drum is installed in the form of end disks 3 and 4 closely connected with each other with rollers 5 and 6, and flexible circuits 7 with guides 8 covering them, under peripheral sections on the disk 3 are equipped with a current collector 9, with which cable 10 is connected at one end, and the other with a power source (not shown).

The axis 2 in the space between the end disks 3 and 4 is provided with a thread 11c with a nut 12 kinematically connected to the flexible circuits 7 and at the same time a cable 10 is fixed on it.

A device for supplying power to a moving object operates as follows.

In cable winding mode.

The movement from the drive 1 is transmitted to the end disks 3 and 4. which receive rotational movement together with the flexible circuits 7, the cable 10 is wound around their peripheral sections. The flexible circuits 7, kinematically connected to the nut 12, rotate on the axis 1, are displaced along it to the side (for example, according to the drawing) of the current collector 9, the flexible circuits 7 and the offset are driven by the wound branches of the cable 10 along the axis of the winding drum. This ensures that the cable 10 is wound on the drum in exactly the same position (at its beginning).

In cable unwind mode.

The movement from the drive 1 is transmitted to the end disks 3 and 4 in the direction opposite to the one described above. In this case, the cable 10 is unwound from the peripheral sections of the flexible circuits 7. The nut 12, displaced from the current collector 9, drives the flexible circuits 7, thereby ensuring strict unwinding as the winding, the cable 10 on the same section of the winding drum.

The presence of the guide 8 under the peripheral sections of the flexible circuits 7 allows you to maintain a constant working diameter of the winding cable of the winding drum.

The proposed design of a device for supplying power to a moving object was manufactured and tested on a bridge chassis operating in a greenhouse. Increased cable durability in Zraza compared to conventional cable management devices.
