Description
Technical field
The present invention relates to elevator safety component technology fields, more particularly to a kind of elevator governor.
Background technology
Elevator is widely used in daily life, but not in time or other failures are former due to elevator maintenance
Cause often can cause elevator that some failures occur, and even result in the generation of accident, and elevator car slipping, hypervelocity downlink etc. are then more
The universal elevator accident origin cause of formation, having occurred some at present prevents the detection device of accidental movement of elevator cage, in lift car
When stopping in hoistway, if there is the car slipping that stops, detection device sends out braking electric signal, elevator brake to brake device for elevator
Device is then braked lift car receiving above-mentioned brake signal, wherein elevator governor is exactly main safety control
Component processed.
Household ladder is broadly promoted and is used, in the Retrofit of Elevator in especially old room, due to spatially
Limitation, existing elevator governor have machine room elevator due to more applicable, are difficult to be applied in household ladder, it is therefore desirable to
A kind of new elevator governor is designed, can adapt to the characteristic of machine-roomless lift, while improving the job security of elevator.
Invention content
The invention aims to provide a kind of elevator governor, it can be applicable in machine-roomless lift, while elevator can be improved
Braking reliability.
In order to achieve the above objectives, the technical solution adopted by the present invention is：
The present invention provides a kind of elevator governors, include the babinet of fixed rope sheave, rope has been rotatably fixed in the babinet
Wheel, the rope sheave is fixed on by rotating middle shaft in the babinet, is fixed with ratchet on the transfer axis, the ratchet with
The rope sheave rotates coaxially, and is located in the babinet above the ratchet and is provided with pawl axis, can on the pawl axis
It is rotationally fixed with oscillating rod, one end of the oscillating rod is fixed with runner, pawl is provided in the middle part of the oscillating rod,
In, the ratchet includes cam and multiple ratchets in back of cam is arranged, and the runner is in contact with the cam face；
The runner is improved in the cam effect amplitude of fluctuation when elevator stall, and then the pawl amplitude of fluctuation is driven to improve
And the ratchet of the back of cam is touched, the pawl is clamped with the ratchet.
For above-mentioned technical proposal, inventor also has further Optimized Measures.
Further, contact-making switch, the touching lever phase that the oscillating rod is vertically arranged with one are provided at the top of the babinet
Even, the other end of the touching lever is pierced by the top of the box and close to the setting of the contact of the contact-making switch, and when elevator stall puts
Lever amplitude of fluctuation increases and then drives the touching lever substantially to swing and touch the contact of the contact-making switch, and institute is touched in touching lever
The contact-making switch powers off stop elevator after stating electric shock.
Further, it being fixed with electromagnet in the top of the box, the electromagnet is arranged close to the contact-making switch,
Triggering is powered so that electromagnet absorption touching lever makes pawl be caught at ratchet to electromagnet when elevator does safety tongs linkage test
Ratchet so that limiter of speed is acted, finally so that safety tongs is acted again.
Further, the babinet includes two blocks of side plates disposed in parallel, is fixed by cover board on the top of two blocks of side plates
Connection, is fixedly connected in the lower part of two blocks of side plates by bottom plate, and the contact-making switch is fixed on the cover board top,
Further, governor spring is provided in the babinet, one end of the governor spring is fixed at babinet, the other end
It is fixedly connected with the oscillating rod, for the limit to the oscillating rod.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
The elevator governor of the present invention has in ratchet and turns at oscillating rod by the way that the ratchet rotated coaxially with rope sheave is arranged
The cam of linkage is taken turns, the cam can drive runner to rotate, so that oscillating rod swings, oscillating rod when normal rotation
On pawl will not touch the ratchet at ratchet, when elevator overspeed, cam rotating speed improves, and drives the runner rotation released with it
So that the amplitude of fluctuation of oscillating rod increases, then pawl teeth portion is caught in the ratchet in ratchet Nei so that limiter of speed stops turning
Dynamic, speed limiter wire rope lifting safety tongs makes elevator stopping, can so realize the speed limit stop of domestic inorganic machine room-free elevator, the electricity
Terraced limiter of speed is simple in structure convenient for arrangement, and work safety, reliability are high.
Further, the present invention is also provided with the touching lever being connected with oscillating rod, is set by the structure of touching lever and contact-making switch
Meter, under normal circumstances touching lever will not contact-making switch, when elevator overspeed, the oscillating rod amplitude of oscillation increase, drive the touching lever amplitude of oscillation additional issue,
Enable touching lever touching switch that switch motion, the work of stop elevator is made to further increase the job security of elevator.
