Speed limiter and safety gear linkage system based on elevator

Abstract

The invention discloses a speed limiter and safety gear linkage system based on an elevator. The speed limiter and safety gear linkage system based on the elevator mainly solves the problems that in the prior art, a speed limiter and safety gear linkage system is complex in structure and high in cost, and especially a speed limiter of an elevator without a machine room is inconvenient to install, maintain, inspect and check. The speed limiter and safety gear linkage system based on the elevator comprises a speed limiter, a speed limiter rope, a guiding adjusting mechanism, a lifting winding drum, a linkage mechanism, a lifting steel rope and safety gears, wherein the speed limiter is arranged on the car roof of a lift car of the elevator, the speed limiter rope is wound around the speed limiter, the upper end of the speed limiter rope is fixedly connected with the top of a shaft of the elevator, the lower end of the speed limiter rope is fixedly connected with the bottom of the shaft of the elevator, the guiding adjusting mechanism is used for detecting whether the speed limiter rope is tensioned or not at any time, the lifting winding drum and the speed limiter are arranged in a coaxial mode, the speed limiter drives the lifting winding drum to rotate through the linkage mechanism, and the lifting steel rope is wound around the lifting winding drum. According to the speed limiter and safety gear linkage system based on the elevator, the speed limiter is arranged on the car roof of the lift car of the elevator, one longitudinal speed limiter rope is adopted, the existing speed limiter and safety gear linkage system of a lift car of the elevator is simplified, and the speed limiter and safety gear linkage system of the elevator are optimized and upgraded comprehensively.

Description

technical field [0001] The invention belongs to special equipment elevators, and relates to an elevator safety protection device, specifically, an elevator-based speed governor and safety gear linkage system. Background technique [0002] The elevator speed limiter and safety gear linkage system is a safety protection device to prevent the elevator from overspeeding and rope breaking, and is an important safety line of defense to protect the safety of passengers. Whether it is in the supervision and inspection of elevator installation or in the annual periodic inspection of elevators, the inspection of the overspeed governor and safety gear linkage system is a very critical item. And according to the "Elevator Supervision Inspection and Periodic Inspection Rules", if the service life of the elevator speed limiter reaches 2 years, or the action of the speed limiter is abnormal, or the seal of each adjustment part of the speed limiter is damaged, the action speed of the speed ...

AI Technical Summary

Problems solved by technology

[0010] When the elevator speed limiter needs to be calibrated, the speed limiter rope must be taken off first. Even for machine-room elevators, it is difficult to take off the speed limiter rope in the elevator machine room; The speed limiter is installed on the top of the elevator shaft, and it is even more difficult to take off the speed limiter rope on the speed limiter
