Abstract
The utility model relates to a bow type current collector for an electric locomotive. In the utility model, a lever is arranged. The upper end of the lever is provided with a touch roll, and the lower end is provided with counterweight; the center part of the lever is supported on a rotating shaft, and the touch roll and the lever are separated by insulating material. Under the action of the counterweight of the lower end of the lever, the touch roll is always butted with electric wire above an electric locomotive. Compared with the existing spring type current collector, the utility model has the advantages of strong adaptability for altitude variation, no easy damage, and easy maintenance.
Description
The utility model belongs to electric locomotive current-collecting device field.
Existing trolley locomotive at random all adopts the spring loaded collector bow, has three problems on its structure, and the one, between contact bar and the electric wire cliding friction, contact bar is easily frayed; The 2nd, collector bow employing spring is regulated the height of contact bar, and setting range is limited, and the height that can not adapt to stringing changes, often occur owing to stringing height vary within wide limits, and the phenomenon of drawing askew collector bow; The 3rd, spring is stretched and is bent frequently fatigue damage easily.
The utility model provides a kind of electric locomotive novel collector bow, has solved the problems referred to above that existing collector bow exists.
The utility model provides a kind of electric locomotive novel collector bow, it comprises the collector bow base, it is characterized in that: the rotating shaft that is parallel to base of pair of brackets supporting on the base, shaft support is in a middle part perpendicular to the lever of base, counterweight is equipped with in the lever lower end, a touch roll that is parallel to rotating shaft is equipped with in the lever upper end, has insulating material to be separated by between touch roll and the lever.This collector bow is installed in the electric locomotive top, and electric wire is positioned at the touch roll top of collector bow, and touch roll is upwards held electric wire all the time under the effect of the counterweight of lever lower end.When driving, along with the variation of electric wire height, the leaning angle respective change of lever makes touch roll hold electric wire all the time.
The utility model utilizes lever principle, has saved spring, makes touch roll under the counterweight effect of lever lower end, holds electric wire all the time; Owing to replaced contact bar with touch roll, wear resisting property improves greatly again; The height adjustment range of touch roll is far longer than the height adjustment range of the contact bar of spring loaded collector bow by the residing brachium decision of touch roll.
Below in conjunction with accompanying drawing the utility model is further described.
Figure one is the utility model constructional drawing.
Wherein, 1-base, 2-support, 3-rotating shaft, 4-counterweight
5-lever middle part, 6-lever bottom, 7-dielectric pin
8-touch roll support, 9-touch roll, 10-roll shaft
Among the figure, support 2 is welded on the base 1, rotating shaft 3 that is parallel to base 1 of support 2 upper support, rotating shaft 3 is supported on lever middle part 5, and the bottom of touch roll support 8 is connected with lever middle part 5 by a pair of dielectric pin 7, roll shaft 11 of touch roll support 8 supportings, be with a touch roll 10 on the roll shaft 11, lever bottom 6 is provided with a counterweight 4, be not subjected under the external force effect, and lever is perpendicular to base.
