Problems solved by technology

However, in an explosive environment, the elevator cannot rely on the action of the speed limiter and the safety gear to stop the elevator, so that the explosion-proof elevator cannot be equipped with a safety device like an ordinary elevator.
It is also infeasible to realize this function on explosion-proof elevators in other ways.

Abstract

The invention discloses an anti-explosion speed limiter. A mechanical triggering centrifugal speed limiter is composed of two systems including a mechanical triggering system and an electromagnetic triggering system. Mechanical triggering is of the centrifugal type. When the wheel speed of the speed limiter exceeds the rated speed, the speed limiter acts, a safety clamp matched with the speed limiter is triggered to act, and equipment such as an elevator or a lifter is shut down. When an emergency triggering system detects that the elevator moves accidentally, the speed limiter is triggered through the power failure of an anti-explosion magnet. The speed limiter is suitable for explosive environments and is an anti-explosion speed limiter which has a function of preventing an elevator carfrom moving accidentally and can be both triggered mechanically and electromagnetically.

Description

technical field [0001] The invention relates to a speed governor, in particular to an explosion-proof speed governor. Background technique [0002] The overspeed governor protection device widely used at present all is to adopt to drive safety gear by overspeed governor, makes hoisting machinery such as elevator, hoist decelerate and stop. Most speed governors use mechanical triggering, that is, when the rotation speed of the speed governor sheave exceeds a certain limit, the centrifugal block on the speed governor sheave rotates under the action of centrifugal force, driving the pawl mechanism on the sheave Action, so that the pressure rope block on the speed governor presses the wire rope of the speed governor, so that the tensioned wire rope is used to pull the safety gear to stop the elevator or its machinery from running. [0003] At present, all the speed governors used in explosive environments are made of non-flammable materials for the speed governor sheave, that i...
