The elevator adjusting-type centrifugation speed limiting device has the advantages that the rotating speed can be controlled, and the function of adjusting the limiting speed in locking is achieved.
Description
Technical field
The present invention relates to elevator assemblies, be specifically related to the centrifugal speed-limit device of elevator adjustment type, this device can adjust the terminal speed of locking.
Background technology
Elevator is a kind of instrument of manned or loading, in the process of elevator manned lift, and excessive velocities.People is subject to overweight or weightless.Human body suddenly overweight or weightless time can get a fright, thus lose manned safety performance, and have impact on the comfort level taken.The illusion can fallen to elevator for people when excessive velocities.This is very important by speed-limit device locking.Existing speed-limit device does not mostly possess terminal speed regulatory function.Therefore just need be further improved original speed-limit device thus reach the object of control limit speed.
Summary of the invention
The deficiency that the present invention overcomes background technology provides the centrifugal speed-limit device of elevator adjustment type, terminal speed when this device can regulate elevator to lock.
The invention provides following technical proposals: the centrifugal speed-limit device of elevator adjustment type, comprise rotor wheel, fixing and locking wheel, centrifugal speed limit assembly, base, described rotor wheel, fixing and locking wheel is connected with described base.Described centrifugal speed limit assembly comprises the first latch hook, the second latch hook, pipe link, return bar, pull back spring, the first clump weight, the second clump weight, and described fixing and locking wheel is provided with ratchet circle, and described fixing and locking wheel is concentric with described rotor wheel.Described first clump weight, second clump weight is respectively at described first latch hook, second latch hook is fixedly connected with, one end of described pipe link is flexibly connected with the tail end of described first latch hook, the other end of described pipe link is flexibly connected with described second latch hook, described first latch hook, the wheel sidewall that second latch hook and described fixing and locking are taken turns is flexibly connected, the wheel sidewall that one end and the described fixing and locking of described return bar are taken turns is flexibly connected, the tail end of the second latch hook described in the other end of described return bar is flexibly connected, described pull back spring is connected with described return bar, described return bar has Telescopic, described pull back spring is in free state, described return bar extends.Described pull back spring is in compressive state, and described return bar shrinks.
Further, described centrifugal speed limit assembly also comprises the 3rd clump weight, the 4th clump weight, and described 3rd clump weight, the 4th clump weight are fixedly connected with respectively at described first latch hook, the second latch hook.
Beneficial effect of the present invention is: described in when excessive velocities, the first latch hook 4, second latch hook 5 gets rid of under the influence of centrifugal force to both sides.Produce locking when hook contact to the described fixing and locking of described first latch hook 4, second latch hook 5 takes turns the described ratchet circle 15 of 2, stop elevator.And described first clump weight 9, second clump weight 10, the 3rd clump weight 11, the 4th clump weight 12 control the size reaching the required centnifugal force of locking, thus control rotating speed.Play the effect of terminal speed when regulating locking.
