Summary of crane sliding contact fault handling
Troubleshooting Summary of crane sliding contact line1. There are sparks in the guide rail of sliding contact line
Main reason: brush surface and guide rail contact is poor.
Treatment method: test guide joints and properly run in brushes to ensure 60% contact area.
2. Large shaking of sliding contact line during operation
Main reason: fork can not absorb transmission error; Linear difference of guide rail; The hanger is loose.
Treatment method: Modify the tractor so that it can freely absorb the transmission error; Adjust the straightness of the guide rail; Tighten the mounting screws.3. Brush side abrasion
The main reason: brush wear, sliding contact line collector is not correct; The fork side force transfer of the tractor is too large.
Treatment method: replace and correct the spring pressure; Replace the traction fork or correct the traction fork.
4, sliding contact collector walking has a large abnormal noise
Main reason: the current is too large; The joint is uneven.
Treatment method: increase the number of collector; Reinstall the rail connection.5, brush wear fast
Main reasons: uneven joints; Excessive load capacity; High spring pressure.
Treatment method: reconnect the guide rail as required; Increase the number of collector; Replace and correct spring pressure.
6, sliding contact collector shell scratches
Main reason: guide rail deformation; The collector rating is not good.
Treatment method: according to fault 2, add shaping clip; Adjust the collector.
7, sliding contact line power off
Main reason: brush climbing in the catheter; The brush is too worn to reach the conductor; Uneven conductor joints; Single collector use; The rail joint is loose.
Treatment method: Detect whether the collector wear seriously, replace the collector; Replace the brush; Readjust the connection node; Double brush collector; Adjust and tighten the connection screws.8. Guide rail deformation, collector movement blocked
Main reason: the ambient temperature is too high; The distance between lifting racks is large or loose.
Treatment methods: the local use of heat insulation board, outdoor sun shield; Increase the number of sliding contact line hanger, correct the conduit, and tighten the screws.
