Embodiment

Referring to figs. 1 through Fig. 3, base 1 is arranged with two through holes 14, rotating shaft 25 on mount pad 2 is located in through hole 14, mount pad 2 can 25 rotate around the shaft, during work, two cross-shaped installations of mount pad 2, the carbon brush 61 in mount pad 2 is facilitated to contact with collector ring, now mount pad 2 aperture position is in working region, carbon brush 61 is arranged on carbon brush holder 6, carbon brush holder 6 is provided with raised line 62, mount pad 2 is provided with groove 23, groove 23 outside is provided with travel switch 24, raised line 62 on carbon brush holder 6 matches with the haptic element on travel switch 24, when carbon brush 61 is not finished, raised line 62 pushes down travel switch 24 haptic element, travel switch 24 is in open mode, two mount pad 2 afterbodys are equipped with spring base 22, extension spring 7 is connected with between spring base 22, extension spring 7 active force drive installation seat 2 afterbody is adjacent to each other, but operationally mount pad 2 needs to be in working region, do not need two mount pad 2 afterbodys adjacent to each other, so be provided with stopping means on mount pad 2 with base 1, operationally limiting two mounting blocks prevents it from rotating, part that mount pad 2 fits with base 1 is provided with guide vane end stop 21, guide vane end stop 21 is provided with draw-in groove 21, base 1 is provided with and corresponding with draw-in groove when working 21 present position runs through groove 12, run through in groove 12 and be equipped with fixture block 3, during work, fixture block 3 snaps in draw-in groove 21, play position-limiting action, base 1 is provided with dovetail groove 13, baffle plate is provided with bottom fixture block 3, baffle plate horizontal direction is connected with connecting rod 311, connecting rod 311 is provided with depression bar 312 parallel with block 31 and in the same way, depression bar 312 matches with dovetail groove 13, and depression bar 312 can slide in dovetail groove 13, and depression bar 312 length is greater than base 1 thickness, stretch out from dovetail groove 13, depression bar 312 is set, staff is mainly facilitated manually to debug, when not needing stopping means to work, by down-pressed pole 312, fixture block 3 falls immediately in draw-in groove 21, device for limiting unlocks.

See Fig. 4 to Fig. 9, block 31 is connected with electromagnet 5 by stage clip 4, stage clip 4 one end is welded on block 31, the other end is welded on electromagnet 5, base 1 is provided with electromagnet 5 holder 15, electromagnet 5 is welded on holder 15, electromagnet 5 is fixed on below base 1 by holder 15, position is just to running through groove 12, electromagnet 5 is controlled by travel switch 24, when carbon brush 61 is not finished, raised line 62 on carbon brush holder 6 and travel switch 24 now fixture block 3 insert in draw-in groove 21, play position-limiting action, prevent mount pad 2 under the effect of extension spring 7, being drawn haptic element to contact, raised line 62 pushes down travel switch 24 haptic element, travel switch 24 is in off-state, electromagnet 5 coil is in off state, electromagnet 5 does not produce magnetic force, under the effect of stage clip 4, block 31 is upwards ejected, go out working region, when carbon brush 61 is soon finished under the ejecting of spring, raised line 62 no longer contacts with travel switch 24 haptic element, travel switch 24 closes, electromagnet 5 conducting produces magnetic force, because block 31 material is irony, under the magneticaction of electromagnet 5, block 31 and electromagnet 5 adhesive, now stage clip 4 is in impaction state, as shown in Figure 5, now fixture block 3 spins off from draw-in groove 21, mount pad 2 is pulled away from working region under the effect of extension spring 7, simultaneously, depression bar 312 stretches out dovetail groove 13 part can also play position-limiting action, prevent mount pad 2 under the pulling force effect of extension spring 7, causing collision, after carbon brush 61 is finished, mount pad 2 is pulled out in working region, certain protective effect can be played to collector ring, prevent accident.

Further, in order to the collector ring of applicable different-diameter, mount pad 2 along the circumferential direction can arrange multiple guide vane end stop 21 and draw-in groove 21,3 are chosen in the present embodiment, different draw-in grooves 21 coordinates with fixture block 3, and two mount pads 2 can be made to realize no angle, the convenient collector ring adapting to different-diameter.

As shown in Figure 10, conveniently rotary mounting seat 2 during debugging, the part that fixture block 3 contacts with draw-in groove 21 is arranged to inclined plane 32, now fixture block 3 can play position-limiting action, but when inwardly regulating mount pad 2 angle, directly rotate mount pad 2, without the need to pressing down-pressed pole 312.

In addition, as shown in figure 11, extension spring 7 method to set up is not unique, respectively independent extension spring 7 is set in mount pad 2 both sides, match with spring base 22 in extension spring 7 one end, the other end is welded on base 2 side, a long extension spring 7 can be replaced with two shorter extension springs 7 like this, make to draw brush carrier overall structure compacter.

The above is only preferred implementation of the present utility model; protection range of the present utility model is also not only confined to above-described embodiment; such as; the material of block 31 differs and is decided to be irony; all can be able to be satisfied the demands by the material of electromagnet 5 adhesive; all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model; should be understood that; for those skilled in the art; do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
