Description

The utility model relates to electrical engineering, in particular to ring current collectors. It is used in mechanical engineering, in particular in transport equipment, namely in excavators, mobile drilling machines, cranes, cable laying machines and cable reels.

A widespread design is the design of the current collector, in which the brush assembly is rigidly fixed opposite the current-carrying ring on the uprights through pre-drilled holes to which are fastened with fasteners.

Closest to the claimed one is the technical solution according to patent RU 168406 U1 B60L 5/18, B60L 5/2 dated 10/10/2016, according to which the RING SECTOR, containing in each phase a contact ring fixed to the main shaft through an insulator, brushes fixed in brush holders fixed on racks. The racks are made in the form of rods having an insulating sheath, and the brush assembly is fixed to them due to the fact that the ends of the brush holder body are made in the form of an open bracket with the possibility of fixing on the rack with a tightening fastening element, while the brush holder body is made of metal. (Scheme for fixing the prototype brush holder on the rack, see Fig. 1)

A disadvantage of the known technical solution is that the clamping element 5 (Fig. 1) in the form of an open bracket, tightened by a bolt 6, does not allow to remove a separately taken brush holder from the rack, which may be required for repair and prevention during operation of the current collector, quick recovery .

The disadvantages of the known technical solution are eliminated by the claimed utility model.

To do this, a design is proposed in which the brush holder is fixed to the rack with two bolts and a clamp bar on each side, which allows you to remove and install the brush holder without removing the racks with the rest of the brush holders. In the claimed design, the annular current collector contains brushes fixed in brush holders rigidly fixed to the racks, the brush assembly is fixed on two racks by a clamping bar and fasteners passing through its through holes attached to the brush holder body, which form a rigid detachable structure, on each side, fixing a brush unit on the rack and allowing to dismantle a separate brush unit without disassembling the entire structure of the current collector.

This design of mounting the brush unit to the racks allows you to remove and install the brush holder without removing the racks with the rest of the brush holders. In this case, the clamping bar is an autonomous attachable part. The edges of the sides of the clamping plate facing the rack and fixing it are made with a recess, making the fixation more stable.

The technical result is an increase in maintainability, improving ease of maintenance during operation of the current collector.

The technical result is achieved due to the design in which a current collector containing brushes fixed in brush holders can be fixed on racks, characterized in that the brush assembly is fixed on both racks with a clamping bar and fasteners passing through its through holes with the possibility of fixation to the housing of the brush holder, which form a rigid detachable structure, while the clamping plate is an autonomous attachable part and is made with a recess on the edges of the sides facing oyke.

The technical solution is illustrated by the images in FIG. 1-2

FIG. 1. The design of the prototype brush holder.

FIG. 2. The design of the brush holder of the claimed technical solution.

Where 1 - brushes;

2 - brush holder housing;

3 - strip;

4 - spring;

5 - clamping element;

6 - a bolt;

7 - clamping plate.

An example implementation.

In the housing of the brush holder 2 containing brushes 1, on two sides opposite the possible arrangement of the racks holes are made for fasteners 6, for example, bolts. The brush assembly is fixed on the rack by the clamping bar 7 using fasteners 6, for example, bolts passing through the through holes in the clamping bar 7. The clamping bar 7 is made in the form of a U-shaped profile with through holes for the fastener, the edges of the sides facing the rack have a recess for best fixation on the rack, while the clamping bar 7 is a standalone attachable part. A positive effect is achieved by the ability to remove one brush holder without having to disassemble the entire structure. This design of mounting the brush unit to the racks allows you to remove and install the brush holder without removing the racks with the rest of the brush holders.

Claims (1)

An annular current collector containing brushes fixed in brush holders with the possibility of fixing on racks, characterized in that the brush assembly is fixed on both racks by a clamping bar and fastening elements passing through its through holes with the possibility of fixation to the brush holder body, which form a rigid detachable structure while the clamping bar is made with a recess on the edges of the sides facing the rack.
