Detailed description of the invention
This detailed description of the invention provides a kind of ground connection recycling device of city rail vehicle, and the Assembly &Disassembly of its constant force spring has good operability, and can effectively dwindle the volume of ground connection recycling device.This detailed description of the invention also provides a kind of city rail vehicle that comprises above-mentioned ground connection recycling device.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, all other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belong to protection domain of the present utility model.
Please refer to Fig. 1-Fig. 3, the ground connection recycling device of the city rail vehicle that this detailed description of the invention provides, comprise brush holder 11 and be removably fixed on the cover plate 12 of brush holder 11, in brush holder 11, be provided with brush, cover plate 12 is provided with erection column 13, is fixed with elastomeric element 14 on erection column 13, and brush holder 11 is provided with the opening stretching into for erection column 13, erection column 13 is inserted in brush holder 11 by opening, so that elastomeric element 14 compresses brush.
So arrange, the ground connection recycling device that this detailed description of the invention provides, in the time that elastomeric element 14 is installed, only need extend into the erection column of cover plate 12 13 in brush holder 11, and make elastomeric element 14 compress the carbon brush in brush holder 11, then cover plate 12 is fixed.
Therefore, the ground connection recycling device that this detailed description of the invention provides need to not be provided for installing the mounting groove of elastomeric element 14 in brush holder 11, has effectively saved installing space, and the shared space of ground connection recycling device also can be dwindled.
In addition, the ground connection recycling device that this detailed description of the invention provides, installs the process of elastomeric element 14 and in brush holder 11, does not carry out, and elastomeric element 14 can be in brush holder external stability on erection column, more convenient operation.
Because elastomeric element 14 and carbon brush offset, for the problem that prevents that elastomeric element 14 from rotate erection column 13 under the effect of the antagonistic force of carbon brush.In the preferred version of this detailed description of the invention, between opening and erection column 13, be provided with the position limiting structure for preventing that erection column 13 from rotating.By the position-limiting action of position limiting structure, can stop erection column 13 to rotate, and then make elastomeric element 14 and carbon brush keep compressing effect.
