Laying several strip conductors, and elevator of constructing install can be slidably connected strip conductor and take electricity current-collector,
Being slidably matched in this way by current-collector and trolley can be to the construction elevator uninterrupted power supply of lifting moving.
Brush with trolley sliding contact is installed, brush is mostly used graphite and is made, therefore also referred to as carbon brush in current-collector.It is existing
Current-collector in brush be usually all one piece of rectangular configuration block structure, brush one end is mounted in current-collector shell, electricity
The brush other end is exposed at outside current-collector shell, and is equipped with compressed spring between current-collector shell and brush, will by compressed spring
Brush makes to keep certain contact pressure between brush and the contact surface of trolley towards the trolley direction pushing tow outside current-collector shell
Power, to realize the connection power supply between brush and trolley.This structure using compressed spring pushing tow brush, contact pressure
It can change with the flexible stroke of compressed spring and change, and during constructing elevator elevating movement, due to brush, cunning
Touching line is influenced by machining accuracy and installation accuracy, and the distance between brush and the contact surface of trolley are to be difficult to ensure uniform one
Cause, therefore drive brush compressed spring flexible stroke be also it is continually changing, lead to connecing between brush and trolley
Touch pressure is also to fluctuate, and the variation of contact pressure is easy the abrasion of aggravation brush, and is unfavorable for reliable and stable power supply.
In addition, due to while brush is constantly flexible in current-collector current-collector also need whole slide, brush is flexible
The lateral force of trolley guide rail application can be also constantly subjected in motion process, it is therefore desirable to there is reliable guiding just to can guarantee electricity
Brush can be stable flexible, and usually only one guiding holding tank installation brush of setting in existing current-collector, guide effect
Poor, the easy skew of brush is amesiality, is also easy aggravation brush wear, and the brush dust after abrasion can further accumulate in collection
Between electric appliance and brush, the use of brush is further influenced.
For the above problems of the prior art, further progress is needed to improve.
