Description
Technical field
The present invention relates to a kind of current-collector, particularly relate to a kind of Novel double-trolley conductor current collector.
Background technology
It is a kind of to the mode of mobile power supply equipment that wiping is powered.Be made up of trolley and current-collector, the brush on current-collector is close to trolley by elastic mechanism, thus the equipment realized in movement is from trolley power taking.This technology is used for driving, crane etc.Because traditional trolley is used for high voltage supply, insulation protection is its overriding concern.But at low-voltage power supply, require that equipment is turned flexibly in situation, it is larger that traditional scheme implements difficulty.
Traditional current-collector adopts parallelogram lifting mechanism, this mechanism rises under the action of the spring, the brush on its top embeds in trolley groove, under the elastic force effect of spring, realize flexible laminating trolley, thus complete from trolley power taking, offset about the mobile device direction of motion can be compensated or realize turning motion.Multi-thread current-collector is combinationally used by multiple single line current-collector.
There is following shortcoming in existing current-collector: 1, radius of turn is generally all comparatively large, and when radius of turn is less, brush can jump out trolley; 2, due to the frictional resistance of brush and plastic insulation shell, or the out-of-flatness of joint plastic housing, occasional causes loose contact.3, higher to construction requirement, difficulty of construction is large, and the cycle is long, and cost is high.Cause the reason of above-mentioned shortcoming as follows: the gap 1, between brush and trolley groove is less, when radius of turn is little, can trolley be gone out.2, be spliced because trolley is generally many.Again because the gap between brush and trolley groove is less, a point out-of-flatness of seam crossing all can cause brush to be beated, even because joint out-of-flatness makes brush pass through thus to break brush.3, for above-mentioned reasons, considerable time is needed just can to complete to the adjustment of trolley.
Summary of the invention
The object of the invention is to provide to solve the problem that a kind of brush contacts with trolley well, reliability is high, by more tight-turning Novel double-trolley conductor current collector.
The present invention is achieved by the following technical solutions:
A kind of Novel double-trolley conductor current collector, comprise holder, brush electricity-fetching mechanism and current-collector supporting mechanism, described brush electricity-fetching mechanism comprises brush and brush mount pad, described current-collector supporting mechanism comprises the first current-collector supporting mechanism and the second current-collector supporting mechanism, described holder comprises the first holder and the second holder, the lower end of described first current-collector supporting mechanism and described second current-collector supporting mechanism is rotationally connected with described first holder and described second holder respectively by fixed axis, described first current-collector supporting mechanism is connected with described first current-collector rotating shaft and described second current-collector axis of rotation respectively with the upper end of described second current-collector supporting mechanism, the top of described first current-collector rotating shaft is all connected with described brush mount pad lower rotation with the top of described second current-collector rotating shaft.
Particularly, the top of described first current-collector rotating shaft is connected with described brush mount pad lower rotation respectively by straight pin with the top of described second current-collector rotating shaft.
Particularly, described current-collector supporting mechanism comprises adjustment pull bar, extension spring and steering base, the upper end of described adjustment pull bar is connected with described current-collector rotating shaft by straight pin, the lower end of described adjustment pull bar is connected with described steering base by straight pin, and the two ends of described extension spring are connected with described adjustment pull bar.
Particularly, described holder comprises the first hold-fast ring and the second hold-fast ring, and described first hold-fast ring is fixedly connected with described second hold-fast ring by screw, spring shim and plain cushion successively.
Further, the both sides of described first hold-fast ring are provided with the jump ring for fixing fixed axis.
Further, the central authorities that described brush mount pad arranges the end face of brush are provided with guide ledges.
As preferably, described brush is copper alloy brush.
The invention has the beneficial effects as follows:
By adopting technique scheme, the present invention is by less radius of turn, exposed owing to adopting bottom trolley, and current-collector brush upper surface contact electricity getting, therefore when larger skew, still can normally work; Brush and trolley can be good contact, owing to there are not other barriers around brush, therefore good contact can be remained; Reduce difficulty of construction and production cost simultaneously, improve efficiency of construction.
