Description

Warm swap formula single hole constant voltage brush carrier

Technical field

The utility model relate to motor or generator brush and with the assembly structure of motor or generator.

Background technology

The brush that closes with motor or generating set assembling has fixedly assembled configuration, and easy-to-dismount plug structure is also arranged.Have only the porous carbon brushing tool that detachable connect-disconnect structure is arranged at present, single brush is and motor or the fixing package assembly of generator.Fixedly the package assembly utmost point is unfavorable for maintenance repair or part replacement maintenance operation, more because can't charged enforcement disassembling section, then must shut down or dress thick and heavy shielding protection and obey operation.And the detachable brush carrier typical structure of porous as depicted in figs. 1 and 2, it comprises the conduction pellet that four hole brush boxs and assembling handle are held, and the front portion of four carbon brush is provided with the whole jam plate by the upper and lower mobile control of flexure strip, and the rear portion applies wearing and tearing displacement pressure by the constant voltage wind spring.There are a lot of technical problems in porous brush carrier structure, at first be that collector ring will have the satisfied axial width H that matches with the porous carbon brush, especially for large-size machine or generator, the collector ring of size as will forging processing, its difficulty is very big, need be with the price of costliness from external import; Moreover, a certain carbon brush electric arc occurs when excessive in many brushes and the group structure, will certainly related bright damage with other carbon brush in the carbon box, and in such porous brush carrier plug operation, can produce bigger electric current at whole unit and distribute impact variation, cause the unit job insecurity; In addition, the whole mechanism of existing porous brush carrier is also also imperfect.Provide a kind of single hole brush carrier so be badly in need of design at present with hot-pluggable function.

Summary of the invention

Goal of the invention of the present utility model is to provide the warm swap formula single hole constant voltage brush carrier of a kind of hot-pluggable dismounting, installation.The warm swap formula single hole constant voltage brush carrier technical scheme that the utility model provides, its major technique content is: a kind of warm swap formula single hole constant voltage brush carrier, comprise the single hole brush box, carbon brush, the conduction pellet, the cartridge clip member and the handle of carbon brush are held, the conduction pellet is slidingly arranged in handle and holds on the axostylus axostyle, brush box is supported and fixed on the conduction pellet, handle is held an end insulating material handle is set, the other end is provided with and passes conductive sleeve end plate jack corner and will conduct electricity the pin of pellet and conductive sleeve locking, handle is held the middle part axostylus axostyle and is provided with a gap segments, pin probes into the indentation, there of gap segments, forms with gap segments locking the spacing of angle of revolution to cooperate.

In above-mentioned overall technical architecture, described cartridge clip member comprises the locking bar that locks carbon brush and the constant voltage wind spring of spring and carbon brush rear end thereof, constant voltage wind spring outer end is fixed on the spring intermediate plate, inserts the brush box chute jointly, is cooperated with the elasticity lock-bit of brush box opening by the hasp of spring intermediate plate.

The warm swap formula single hole constant voltage brush carrier technical scheme that the utility model provides has remedied the technological gap that existing single brush can not be shut down warm swap.The warm swap formula single hole constant voltage brush carrier dismounting connect-disconnect structure of the technical program makes the collector ring 15 size h that are mated dwindle greatly on the one hand, particularly for large-size machine or generator, just can adopt domestic collector ring product, realize the technical purpose of low-cost input; Again on the one hand, the operation of single hole constant voltage brush carrier warm swap is little for the electric current assignment affects of whole unit, and the structure of the technical program formation has accurately, and action cooperates, easy and simple to handle and safe, reliable, can not produce big influence, and reduce by the brush scope of flash burn to whole unit work.

Embodiment

The warm swap formula single hole constant voltage brush carrier that the technical program provides, its concrete enforcement structure as shown in Figure 3, form and include single hole brush box 4, carbon brush 3, conduction pellet 9, the cartridge clip member and the handle of carbon brush 3 hold 16, brush box 4 is supported and fixed on the conduction pellet 9, handle is held 16 1 ends and is fixed with the handle of being made by insulating material 11, another top is provided with pin 6, conductive sleeve end plate 7 is provided with the jack 13 that can allow pin 6 pass through just, promptly only allow handle to hold 16 pin 6 and pass jack 13 with single directional angle, be equipped with the alignment concavity groove 14 that can coincide with pin 6 with 90 ° of angles of jack, when handle is held in the 16 insertion conductive sleeves 8, pin 6 passes from end plate slotted eye 13, hold handle 11 and clockwise rotate 90 ° thereafter, under the effect of the elastic pressure between conduction pellet 9 and the conductive sleeve 8, pin 6 is cooperated with location notch 13, the pellet 9 that will conduct electricity is locked together with conductive sleeve 8, this structure has effectively avoided unit work to shake the vibrations skew of the conduction pellet 9 that causes, makes integral assembling structure more stable down in working order.

The cartridge clip member of carbon brush 3 comprises locking bar 12 and wire spring 5 thereof that locks carbon brush and the constant voltage wind spring 2 that acts on the carbon brush rear end.Constant voltage wind spring 2 outer ends are fixed on the spring intermediate plate 1, insert the brush box chute jointly, are cooperated with the opening elasticity lock-bit of brush box chute by the hasp of spring intermediate plate 1, and locking constant voltage wind spring 2 positions enable carbon brush 3 is continuously applied wearing and tearing displacement pressure.As shown in Figure 3, described locking bar 12 is the hinged lever that is arranged at brush box 4 belows, and provides coupling mechanism force by wire spring 5.Brush box one end of locking bar 12 is provided with curved lock dog, and the other end has following bent-up end.Handle is held 16 middle part axostylus axostyles and is provided with a gap segments, and in this enforcement structure, this gap segments is the semiaxis section, and this semiaxis section cooperates with pin 10, and two transpositions of holding 16 pin 6 according to handle design determines position and the length of pin 10 in the semiaxis section.The semiaxis section while is as the eccentric body of 12 times bent-up ends of locking bar, when conduction pellet 9 plug-in mountings put in place, and when going to pin 6 latched positions, as shown in Figure 3, the height of the semiaxis section 12 times bent-up end jack-up of elastic force locking bar of naming a person for a particular job, curved lock dog moves down and breaks away from carbon brush 3 on the elastic force locking bar 12, makes carbon brush 3 enter the operating state that cooperates with collector ring 15; When needs are extracted, rotate handle 11, handle is held 16 pin 6 and is gone to slotted eye 13 positions, meanwhile under the elastic force effect of spring 5, the following bent-up end of locking bar 12 moves to the low spot of semiaxis section, thereby curved lock dog on the check lock lever front end is lifted the locking carbon brush, and can extract brush carrier integral body in the conductive sleeve this moment, carries out daily detection and maintenance.
