Problems solved by technology

The maintenance space for the installation of the speed limiter of the elevator with machine room is generally narrow, while the speed limiter of the elevator without machine room is installed in the elevator shaft, and the maintenance and inspection (inspection) activities can only be carried out on the top of the elevator car. Inconvenient and prone to personal injury
For example, according to the requirements of elevator safety standards (such as "Elevator Manufacture and Installation Safety Code" (GB7588), "Elevator Supervision Inspection and Periodic Inspection Rules - Traction and Forced Drive Elevators" (TSG T7001) When conducting regular on-site and online inspections (calibrations) of the speed of the gearbox, the inspection (calibration) operation is inconvenient, the operation process is likely to cause personal injury and damage to the inspected equipment, the inspection (calibration) results are inaccurate, and the efficiency is low. Not advanced question
When there is damage or failure inside the elevator speed limiter, the use of the elevator must be stopped, and online maintenance is also inconvenient and unsafe

Abstract

The invention discloses a separable elevator speed limiter which comprises a machine seat, a speed limiter rope wheel mechanism and a speed monitoring mechanism. The speed limiter rope wheel mechanism is mounted in the machine seat, and the speed monitoring mechanism and the speed limiter rope wheel mechanism are arranged separately and coaxially. The separable elevator speed limiter can effectively limit speed of an elevator car and can meet requirements on convenience in demounting, inspection and repairing; offline operation can be realized during inspection (checking) or repairing, so that more convenience is realized, and potential safety hazards can be eliminated.

Description

technical field [0001] The invention discloses an elevator speed limiter, in particular to a detachable elevator speed limiter. Background technique [0002] With the increasing use of elevators in people's lives, the safety of elevators has also attracted more and more attention. The elevator speed limiter is a safety device to prevent the elevator car from overspeeding, especially when the elevator car stalls and falls. The action principle of the protection device is to trigger the action of the mechanism through the action of centrifugal force, and stop the elevator car on the elevator guide rail through the linkage of the speed limiter, that is, the safety gear. At present, the commonly used elevator speed limiter device adopts the structure of a speed limiter sheave, please refer to the attached figure 1 to attach Figure 4 The internal structure of the conventional elevator speed governor is that the centrifugal hammer of the speed governor, the centrifugal hamm...
