Abstract
The utility model relates to a rolling trolley bow contactor solving the problems that trolley bows connected with power cords used by various existing electric locomotives of trolleys all have slide contact, quick abrasion and short service life. The rolling trolley bow contactor comprises a trolley wheel, a trolley wheel seat, a mercury box and an electrical conduction wheel which are matched with each other, and the shaft of the trolley wheel is provided with soft metal and a side wheel in static match way. The rolling trolley bow contactor has the advantages that the rolling trolley bow contactor is adopted, the trolley wheel is contacted with the power cord in balanced way under the action of a spring installed on a bracket, and the contactor can also rotate in the horizontal direction in a restricted way in order to adjust the direction conformance of the trolley body and the power cord. The rolling trolley bow contactor has small abrasion and long service life.
Description
One, technical field
The utility model is a kind of rolling electric car bow contact.
Two, background technology
At present, various electric car, car that electric locomotive is employed to be connected with power lead bow all be moving contact, quick abrasion, service life is short.
Three, summary of the invention
The purpose of this utility model is to solve above-mentioned existing problem, and a kind of rolling electric car bow contact of long service life is provided.
The utility model is achieved in that roller is installed on the roller mount by antifriction-bearing box, and roller mount is connected with support by bearing pin.At the axial region close fit of roller soft metal is installed, reached side wheel; Antifriction-bearing box tightens by jump ring.Roller one end passes seal ring and enters in the mercury boxes that is connected and composed by upper cartridge body, lower box body, by nut conductive casters is fixed on roller end portions.Mercury boxes injects mercury, Seal Oil or water by the oil hole on it, and oil hole seals by bolted; Mercury boxes is by being bolted on the roller mount, and with the touch block close-coupled.
Advantage of the present utility model is, adopts above-mentioned rolling electric car bow contact, and its roller contacts with power lead is balanced under the effect of the spring that support is installed, the all right limited rotation of horizontal direction of contact, to adjust the conformability of vehicle body and power lead direction, it is little to wear and tear, long service life.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view with 90 ° of power lead and roller, mercury boxes partial rotation;
Fig. 3 is the structural representation at power lead and roller increase spring chain;
Fig. 4 is the structural representation at power lead and roller increase caterpillar chain;
Five, the specific embodiment
Describe in detail below in conjunction with accompanying drawing: as shown in the figure, whole rolling electric car bow contact is installed in by on the car bow support 3 that pushes away on the spring force, and roller mount 1 is connected with support 3 by bearing pin 2.Roller mount 1 adopts insulating material to make; With the axial region close fit of roller 9 soft metal 7 is installed, reached side wheel 6; Antifriction-bearing box 5 is by jump ring 4 chuckings.Roller 9 is installed on the roller mount 1 by antifriction-bearing box 5, and axial region one end of roller 9 passes seal ring 17 and enters in the mercury boxes that is connected and composed by upper cartridge body 10, lower box body 16, conductive casters 11 is fixed on the shaft end of roller 9 by nut 12.Mercury boxes injects mercury 15, Seal Oil or water 14 by the oil hole on it, and oil hole is by bolt 13 fit sealings; Mercury boxes is by being bolted on the roller mount 1, and with touch block 18 close-coupled.
During use, the cable on touch block and the car is connected.Two rollers are kept in touch with power lead 8 under the effect of the spring force of institute's mounting spring on the support and roller groove all the time, avoid in normal mutual disengaging in service.Soft metal 7 can be protected power lead and strengthen static friction force, and when body movement, roller 9 leans on the static friction force driven rotary with power lead 8; No matter conductive casters 11 is to rotate or when static, always some immerses in mercury, electric current and the mercury boxes conducting from roller.
In order to increase car bow and power lead area of contact, can between roller and power lead, increase a spring chain or a caterpillar chain of making of conductive material.
