Embodiment Construction

[0022] The overspeed governor is suspended from the support structure by means of a jig 1 . In Fig. 1 the jig is suspended, in this case the fixing point 1a to the support structure is at the top of the jig. Fixing points to the support structure may be formed otherwise, for example at the bottom of the assembly frame. On the assembly frame 1 is a fixed shaft 2 on which is a load-bearing mounted free-rotating rope wheel 3 mounted via a ball bearing. A brake 5 is fixed to the shaft 2 adjacent to the rope wheel 3 , the braking force of which can be set appropriately, and includes a brake disc 6 . The overspeed governor provided as an example can be considered as a device in which most of the parts rotate around said axis 2 , or as a device in which most of the parts are equipped to rotate about said axis 2 .

[0023] The rope pulley 3 supports two diametrically opposed axle columns 14 on the side on which the brake 5 is located, above the brake disc 6 (ie outside the diameter ...

Abstract

A method for tripping safety gear of an elevator, at a speed lower than a gripping speed of the elevator may include: slowing a rope sheave of an overspeed governor of the elevator using a device adapted to slow the rope sheave; disconnecting an actuator connected to the overspeed governor from movement of the rope sheave when the device slows the rope sheave; and tripping the safety gear in an overspeed situation using a rope driving the overspeed governor via the rope sheave. An appliance for tripping safety gear of an elevator may include: an overspeed governor; a rope sheave of the overspeed governor; a device adapted to slow the rope sheave; and an actuator connected to the overspeed governor that is arranged to disconnect from movement of the rope sheave when the device adapted to slow the rope sheave acts to slow the movement of the rope sheave.

Description

technical field [0001] The invention relates to a method for releasing said safety device in an elevator at a speed lower than the gripping speed of said elevator, wherein in an overspeed situation, by driving said overspeed governor via a rope sheave rope to take place for the release of said safety device; and to a device for releasing said safety device in an elevator at a speed lower than the gripping speed of said elevator, wherein in an overspeed situation, The release of the safety device occurs by driving the rope of the overspeed governor via a rope pulley, wherein the device is used in an elevator to release the safety device at a speed lower than the clamping speed of the elevator, wherein in The release of the safety device in an overspeed situation takes place via a rope pulley by driving the rope of the overspeed governor. A specific object of the invention is to achieve clamping when the elevator leaves a floor in unintended motion. Background technique [0...
