Particularly, the top of the top of the described first current-collector rotating shaft and the described second current-collector rotating shaft is rotationally connected by straight pin and described brush mount pad bottom respectively.
Particularly, described current-collector supporting mechanism comprises adjusts pull bar, extension spring and steering base, the upper end of described adjustment pull bar is connected with described current-collector rotating shaft by straight pin, the lower end of described adjustment pull bar is connected with described steering base by straight pin, and the two ends of described extension spring are connected with described adjustment pull bar.
Particularly, described holder comprises first hold-fast ring and second hold-fast ring, and described first hold-fast ring is fixedlyed connected with described second hold-fast ring with plain cushion by screw, spring shim successively.
Further, the both sides of described first hold-fast ring are provided with for the fixing jump ring of fixed axis.
Further, described brush mount pad central authorities that the end face of brush is set are provided with guide ledges.
As preferably, described brush is the copper alloy brush.
The beneficial effects of the utility model are:
By adopting technique scheme, the utility model can be by less radius of turn, exposes bottom the trolley owing to adopt, and contact power taking with current-collector brush upper surface, so under the situation of bigger skew, still can operate as normal; Brush and trolley can excellent contact, owing to do not have other barriers around the brush, so can remain excellent contact; Reduce difficulty of construction and production cost simultaneously, improved efficiency of construction.
