Remote reset elevator overspeed governor

Abstract

The invention relates to a remote reset elevator overspeed governor. The elevator overspeed governor comprises an overspeed governor support plate, a rope wheel fixed to the overspeed governor supportplate through a main shaft, a centrifugal mechanism arranged on the rope wheel and moving along with the rope wheel, a switch striking plate rotatably arranged on the overspeed governor support plate, and a switch mechanism in linkage with the switch striking plate; the switch striking plate is fixedly connected with one reset rod, a limiting plate is fixed to the overspeed governor support plate, and a limiting hole is formed in the limiting plate; the reset rod penetrates through the limiting hole and can rotate around the limiting hole, and a long-strip-shaped through groove is formed in the lower portion of the reset rod in the length direction of the reset rod; and a steel wire rope is vertically arranged in the through groove in a penetrating mode, and the steel wire rope is drivenby a rotating motor to drive the switch striking plate to rotate and reset. The remote reset elevator overspeed governor is simple in overall structure, accurate in resetting and accurate in resettingof the switch striking plate, and reliable resetting of the elevator overspeed governor when an electric appliance switch needs to be reset can be guaranteed.

Description

technical field [0001] The invention relates to an elevator safety component, in particular to the field of elevator speed governors, in particular to a remote reset type elevator speed governor. Background technique [0002] Elevators are widely used in people's daily life. In order to ensure people's safety and prevent elevator overspeed from causing harm to people, elevator overspeed governors are used as safety components for monitoring elevator overspeed. When the elevator has an overspeed fault or when the elevator linkage function is tested, the speed limiter completes the trigger action. When it is necessary to reset the speed limiter, for the machine room-less speed limiter, the maintenance personnel need to perform remote operation to reset the speed limiter. In addition to resetting the mechanical part of the speed limiter, it is also necessary to The electrical switch is remotely reset. The existing mechanisms for resetting the electrical switch mostly use the m...

When it is necessary to reset the speed limiter, for the machine room-less speed limiter, the maintenance personnel need to perform remote operation to reset the speed limiter. In addition to resetting the mechanical part of the speed limiter, it is also necessary to The electrical switch is remotely reset. The existing mechanisms for resetting the electrical switch mostly use the motor to drive the connecting rod to rotate, and then drive the switch connected to the connecting rod to return to the original position. The structure of the connecting rod reset will lead to a larger volume of the elevator speed limiter. Large, and the connecting rod is prone to jamming and other failures
