Utility model content
The purpose of this utility model is the current collector providing a kind of hollow type, and the problem of hydraulic oil pipe can not be walked in the center in order to solve current-collector of the prior art.
The utility model discloses a kind of current collector of hollow type, comprising: there is the rotor module 1 of hollow via-hole, stator modules 2, central drum 3 and several copper rings 4, wherein,
Rotor module 1 is positioned at the top of stator modules 2, and central drum 3 is interted in the hollow via-hole of rotor module 1 and stator modules 2;
The diameter of the hollow via-hole of several copper rings 4 is greater than the diameter of central drum 3, several copper rings 4 be socketed in be positioned at stator modules 2 central drum on;
The inside of rotor module 1 is provided with several binding posts 5, and several binding posts 5 are connected with several copper rings 4 through central drum 3 respectively by wire;
Several copper rings 4 are respectively arranged with multiple carbon brush 6, and the multiple carbon brush 6 on each copper ring 4 are connected by wire.
Further, the hollow via-hole of central drum 3 is used for hydraulic oil pipe and walks, and the diameter of its hollow via-hole is 100 ~ 200mm.
Further, carbon brush 6 adopts graphite Cu alloy material to make.Further, rotor module 1 and stator modules 2 are respectively arranged with maintenance window 7.
The beneficial effect of above-mentioned technical solutions of the utility model is adopted to be: the utility model is by carrying out hollow design to current-collector, hydraulic oil pipe need not be detoured from the outside of current-collector, thus directly walk from the hollow via-hole of current-collector, therefore, be not wound around with other component interference, cable is not easy to wear, frangibility, electric conductor do not expose, there is not electricity consumption danger etc.
