Elevator roller pressure adjustment assembly and adjustment method, elevator guide shoe and elevator system

Abstract

An elevator roller pressure adjustment assembly includes: a contact member, fixed relative to at least one roller configured on an elevator car or counterweight, the roller being in rolling contact with an elevator guide rail and defining a running trajectory of the elevator car or counterweight along the elevator guide rail during normal operation of an elevator system; and a cooperating member, mounted at a preset position on the elevator guide rail and arranged outside the running trajectory without contacting the roller, and configured to come into pressure contact with the contact member to generate a force to be exerted to the contact member when the elevator system is in a preset state such that the elevator car or counterweight stops in proximity to the preset position, the force at least reducing a contact pressure between the roller and the elevator guide rail.
