In addition, when there being multiple carbon brush to be controlled by flexible member extruding respectively, the elastic force of flexible member is not quite similar, usually cause the rate of wear of different carbon brush different, thus easy initiating failure, and the dust produced that weares and teares in work may pollute generating set, and the charged position of unit may be caused to be short-circuited accident, therefore, those dust must be collected, Normal practice be by outside whole collector ring and all carbon brush dust gathering arrester that an insulating material is made cover, and offer some dust collection holes at dust gathering arrester periphery, be connected on dust catcher by pipeline again, this way is owing to drawing badly, be unfavorable for the heat radiation of collector ring, there is potential safety hazard, and program carbon brush checks, change trouble.
Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of difficult drop-off, long service life, and can ensure that the extruding force suffered by each carbon brush is identical, not easily breaks down, and the carbon brush structure that dust collection is effective, easy to maintenance.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of carbon brush structure, the carbon brush body comprising carbon brush base and be fixed on the carbon brush base on this carbon brush base and be arranged in this carbon brush base, wherein: be evenly distributed with in described carbon brush base some to carbon brush body size, carbon brush pipe that shape is corresponding, this carbon brush pipe is all located at grade, is provided with elastic supporting member for supporting optical member between this carbon brush base and carbon brush base; There is extraction wire this carbon brush body inside, this wire one end is connected with this carbon brush body by bolt, the other end is connected with the copper sheet cap being arranged on dust suction distributor surface by bolt, these copper sheet cap two ends are bent with copper sheet bar, the flexible flexible insulated hose of this wire outer race, this elastic insulated flexible pipe one end is connected with dust suction distributor, and the other end is connected with the insulation dust-absorbing box being connected to carbon brush body side.
Preferably, above-mentioned a kind of carbon brush structure, wherein: described wire is copper core flexible cord; Elastic supporting member for supporting optical member is spring; Carbon brush base is dumbbell shaped.
Again preferably, above-mentioned a kind of carbon brush structure, wherein: described wire and carbon brush body are bolted position and are arranged on this carbon brush body inner hub location.
More preferably, above-mentioned a kind of carbon brush structure, wherein: described bolt is eyelet bolt.
Further preferably, above-mentioned a kind of carbon brush structure, wherein: described insulation dust-absorbing box and carbon brush body connected mode are movable connection, this connecting portion is in this carbon brush body center position place.
Further more preferably, above-mentioned a kind of carbon brush structure, wherein: described elastic insulated flexible pipe is respectively arranged with sealing ring with insulation dust-absorbing box, dust suction distributor junction.
The utility model technique effect is mainly reflected in the following aspects:
(1) wire one end that carbon brush body inside is drawn is connected with this carbon brush body by bolt by the utility model, the other end is connected with the copper sheet cap being arranged on dust suction distributor surface by bolt, wire of comparing is pressed by copper sheet chieftain wants much firm, and be bolted welding of comparing, keep in repair easy, add the useful life of carbon brush.
(2) the utility model carbon brush pipe is all located at grade, elastic supporting member for supporting optical member is provided with between carbon brush base and carbon brush base, elastic supporting member for supporting optical member supports the multiple carbon brush on same plane simultaneously, make the extruding force suffered by each carbon brush identical, can ensure that the rate of wear is substantially identical like this, thus not easily break down.
(3) the flexible flexible insulated hose of the utility model wire outer race, this elastic insulated flexible pipe one end is connected with dust suction distributor, the other end is connected with the insulation dust-absorbing box being connected to carbon brush body side, eliminate traditional huge dust gathering arrester, simplify the structure, each carbon brush side is equipped with insulation dust-absorbing box and collects dust, dust collection effect is more traditional good, this insulation dust-absorbing box and carbon brush body connected mode are movable connection in addition, this connecting portion is in this carbon brush body center position place, facilitate current check and the maintenance of device, prevent carbon brush discontinuity generation eccentric wear simultaneously.
Accompanying drawing explanation
Fig. 1: a kind of carbon brush structural representation of the utility model.
In figure, the implication of each Reference numeral is: 1-carbon brush base, 2-carbon brush base, 3-elastic supporting member for supporting optical member, 4-carbon brush body, 5-wire, and 6-insulate dust-absorbing box, 7-flexible insulated hose, 8-dust suction distributor, 9-copper sheet cap, 10-copper sheet bar, 11-sealing ring.
