BRAKING SYSTEM RESETTING MECHANISM FOR A HOISTED STRUCTURE

摘要

A braking system resetting mechanism for a hoisted structure includes a guide rail (14) and a brake member (10). Also included is a brake member actuation mechanism (12) operatively coupled to the brake member and configured to magnetically engage the guide rail to actuate the brake member from a non-braking position to a braking position. Further included is an outer structure having a slot (64) configured to guide the brake member actuation mechanism, wherein the slot includes a first angled region and a second angled region that intersect at an outer location. Also included is a spring loaded lever (202) operatively coupled to the outer structure and configured to engage the brake member actuation mechanism during a resetting operation, wherein the spring loaded lever biases the brake member actuation mechanism toward the outer location of the slot of the outer structure to disengage the brake member actuation mechanism from the guide rail.

1. A braking system resetting mechanism for a hoisted structure comprising:
a guide rail configured to guide movement of the hoisted structure; a brake member operatively coupled to the hoisted structure and having a brake surface configured to frictionally engage the guide rail, the brake member moveable between a braking position and a non-braking position; a brake member actuation mechanism operatively coupled to the brake member and configured to magnetically engage the guide rail to actuate the brake member from the non-braking position to the braking position; an outer structure having a slot configured to guide the brake member actuation mechanism, wherein the slot includes a first angled region and a second angled region that intersect at an outer location; and a spring loaded lever operatively coupled to the outer structure and configured to engage the brake member actuation mechanism during a resetting operation, wherein the spring loaded lever biases the brake member actuation mechanism toward the outer location of the slot of the outer structure to disengage the brake member actuation mechanism from the guide rail.
