What are the common faults in the safety trolley? How to solve it?
First, the main cause of the power failure of the trolley line: The brush is climbing in the conductor; the brush is worn badly and cannot touch the conductor; the conductor connection is not even; the single collector uses; the guide rail connector is loose.
Treatment method: detect whether the collector brush wear is serious, replace the collector brush; replace the brush and re-adjust the connection node; use double brush collector; re-tighten the connection screw.
Second, the rail deformation, the collector is blocked Main reasons: the ambient temperature is too high; lift rack spacing or loose treatment method: local use of insulation board, outdoor sun visor; increase the number of trolley wire lifting rack, correcting conductor And tighten the screw.
Third, the major causes of shaking the touch line during work: the fork can not absorb the transmission error; the straightness of the guide rail is poor; the lifting rack is loose.
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.
Fourth, the brush wears fast mainly causes: The joint is not smooth; The carrying capacity is too big; The spring pressure is big.
Treatment method: Reconnect the guide rails as required; increase the number of current collectors; replace and correct the spring pressure.
5. Main reasons for brush abrasion on the side: Brush wear, improper positioning of the current collector, excessive force transmission on the pull-out side of the retractor.
Treatment method: Replace and correct the spring pressure; replace the traction fork or correct the traction fork.
Sixth, there are sparks in the conductor: brush surface and rail bad contact.
Treatment method: Detect the conductor joints, brush the brushes properly, and ensure 60% contact area.
VII. There are major abnormal noises when the trolley wire is running. The main reason is that the current is too large; the joint is not even.
Treatment method: increase the number of collectors; re-adjust the rail connection.
Eight, sliding wire collector shell scratch main reasons: conductor deformation; collector positioning is not good.
Treatment method: According to the second troubleshooting, increase the hanging rack; adjust the collector.
