1. Main reasons of brush side scrape: Brush wear, current collector position is not correct; the pull force of the puller side of the retractor is too large.
Treatment method: Replace and correct the spring pressure; replace the traction fork or correct the traction fork.
2. The major causes of shaking on the trolley line during work are: the fork cannot absorb the transmission error; the straightness of the guide rail is poor; and the hanging rack is loosened.
Treatment method: Correct the tractor so that it can absorb transmission errors freely; adjust the straightness of the guide rails; tighten the lifting rack screws.
3, there are sparks in the conductor: Brush surface and rails bad contact.
Treatment method: Detect the conductor joints, brush the brushes properly, and ensure 60% contact area.
4, brush wear fast reasons: joints are not smooth; carrying capacity is too large; spring pressure.
Treatment method: Reconnect the guide rails as required; increase the number of current collectors; replace and correct the spring pressure.
