Abstract

The utility model relates to a rotary type current-collector of a bow-type collector of an electric trolley. A frame of the existing bow-type collector is provided with a cylindrical current collecting body substituting a sliding plate type current collecting bow head. The utility model can be composed of a plurality of cylindrical current collecting bodies which are connected in parallel to make the current collection of the bow-type collector be converted to a composite current collection mode of slide and rotation combination from a single slide mode. The abrasion between bow nets and the accidents of the bow nets can both be reduced, and meanwhile, the utility model can stop the bow-type collector from leaving the net or pulling an arc during the running, and the interference and the damage to inner electric parts and outer communication of the trolley caused by the bow-type collector can be reduced. The device has boarder prospect as a current collector of a high-speed electric trolley.

Description

Rotary electric motorcycle pantograph current collection device

The utility model relates to a kind of current collection device of block of bow collector of electric locomotive, and especially electric express locomotive is subjected to flow device.

At present, block of bow collector of electric locomotive is to contact with contact line conducting wire with slide plate, moves to slide with locomotive and is flowed.Not only exist serious abrasion between slide plate and contact line conducting wire, and, make slide plate have the trend of upset because of the metal on the contact surface heats up in a steamer or slider groove etc. all will increase mutual friction force.Gently then cause point or line contact between bow net, slide plate occurs beating from the net arcing, produces metal once more to heat up in a steamer, and causes high order harmonic simultaneously in locomotive electric apparatus, influences locomotive operation, disturbs radio station; Heavy then cause and scrape bow and scrape disconnecting net-fault lead, cut off traffic etc. than serious accident.

The purpose of this utility model proposes for addressing the above problem.

The purpose of this utility model is achieved in that on existing pantograph framework, installs by cylinder, hollow rotating shaft, drainage ring, the rotatable cylindrical shape of inducing angle, bearing arrangement, carbon brush configuration and spring installation etc. to be formed to be subjected to fluid to reach the purpose that locomotive is flowed.After contact line conducting wire and cylindrical shape were contacted by the cylinder of fluid, with the locomotive operation, under the effect of contact point resistance, cylinder rotated, and makes the simple slip between bow net become the slip that can roll.Cylinder is delivered to electric energy on the pantograph framework by synchronous drainage ring that rotates and carbon brush, soft line etc. in its two ends hollow rotating shaft as charged body, realizes the compound stream mode that is subjected to of trackslipping and combining.Rolling between bow net can avoid the impact resistance causes between bow net bow to beat disengaging arcing that the net lead produced and the even more serious bow accident of scraping; The drainage ring contacts the motion campaign with bow with carbon brush, can realize the purpose that smooth contact is steadily flowed.The high-power electric locomotive is subjected to stream can adopt the rotary current collection device that composed in parallel by fluid by a plurality of cylindrical shapes.

Since adopted above-mentioned trackslip combine be subjected to the stream scheme, can improve pantograph and be subjected to the stream ability, improve the locomotive electric apparatus working environment, reduce accident between pantograph, realize the purpose that the locomotive high-speed smooth is flowed.

Be described further below in conjunction with accompanying drawing.

Accompanying drawing is that single cylindrical shape is subjected to fluid longitudinal sectional drawing (half of its symmetry of only drawing).

Among the figure 1, cylinder 2, induce angle 3, hollow rotating shaft 4, drainage ring 5, bearing arrangement 6, spring installation 7, upper frame 8, soft braided wire 9, carbon brush configuration 10, dividing plate

As shown in the figure, cylindrical shape is subjected to fluid in the welding hollow rotating shaft (3) of cylinder (1) two ends, and dividing plate (10) and drainage ring (4) are set in the hollow rotating shaft (3).Bearing arrangement (5) and carbon brush configuration (9) with induce angle (2) to be fixed as one, through bearing installation in hollow rotating shaft (3).Cylinder (1) is a conical transition face with inducing the transition at angle (2).Connect carbon brush configuration (9) with soft braided wire (8) and induce angle (2) and upper frame (7).In bearing arrangement (5) below spring installation (6) is set, make its cylindrical shape be subjected to the fluid overall fixed on pantograph upper frame (7) through spring installation (6), and under the action of the spring of spring installation (6), can move up and down, its amount of movement is determined by the stop on the spring installation (6).Spring installation (6) also plays the effect that the restriction cylindrical shape is subjected to fluid degree of freedom on other direction, makes it in 1 to 2 millimeter scope.
