Facilitate worker that suitable tools is selected to dismantle.When bolt rotation is drawn high, to ensure driving gear and driven tooth
Wheel keeps horizontal effectively contact.By adjustable spring as the size that bolt extracts traction sheave goes up and down lifting pressing plate.Raising is draged
The convenience of running wheel replacement mechanism.
Preferably, the bolt is hexagonal full-thread bolt, the bolt length is 140mm~200mm.
Guarantee that the effective of bolt uses length.
The utility model can reach following effect:
The utility model provides a kind of traction sheave replacement mechanism for slim traction type elevator, with prior art phase
Compare, has compact-sized, convenient for disassembly and assembly and service life long.It solves the problems, such as that traction sheave extraction is replaced, is replaced with
Originally it can substantially reduce, and the service life of traction machine can be extended.
