Maintenance and inspection of the elevator guide shoe

Maintenance and inspection of the elevator guide shoe
1) side of the boot liner of the car elevator guide shoe and the guide rail gap is 0.5 ~ 1mm. Elastic sliding elevator guide shoe boots lining the rail top surface without gaps, elevator guide shoes spring adjustment range does not exceed 5 mm. Fixed sliding elevator guide shoe boots lining the rail top surface gap of 1 to 2 mm. Redirection boots boots lining the rail top surface gap is not more than 2.5 mm. Rolling elevator guide shoes wheel and rail surface gap of 1 to 2 mm.
2) the car and the counterweight run at the same level, check the car and the upper counterweight elevator guide shoe. Back and forth to both sides of the car or counterweight framework, you can check the size of the backlash and wear boots lining, but also to check the hard and soft spring. If the headspace is too large, you can remove the boots lining in the top surface of the gasket adjustment. Backlash is too large, if it is embedded chip Shoe lining, can be screwed into the side of the shoe lining bolt adjustment backlash. Integral boots gasket on the back side of the boots lining lining can be adjusted so that the gap * side is slightly larger, but because of structural reasons, the effect is not as good as the embedded chip, so the best way is to be replaced with new boots lining.
Check the elevator guide shoes and the car frame, re-frame fastening, preferably with spring washers to prevent loosening of the nut.
3) Shoe lining badly worn, the gap is too large or install skew, cause the car with "chew Road" phenomenon. "Bite the Road" phenomenon following signs to determine: a narrow and bright side of the rail traces, traces on with serious glitches; boots lining the side speakers and glitches; car driving, especially at the start of peace layer deviate pendulum. "Bite the Road": rails twisted, crooked or loose; installation of the upper and lower elevator guide shoes is not, and is inconsistent with the guide clearance; deformation of the car frame or shoe seat loose bolts; Dimensions lined boots too small boots head shaking.
4) always pay attention to rail lubrication, timely removal of dirt inside the boots lining. Guide face of the sliding elevator guide shoes required cleaning, refueling once a week, and cleaned once a year. If automatic refueling device with HJ-40 lubricating oil, no automatic refueling device with calcium-based grease. Rolling elevator guide shoes the rail face without lubricants, but its face to be cleaned, the wheels in the operation should not be obvious slippage. Rolling elevator guide shoes bearing monthly Note calcium grease, cleaning once a half year.
