Description
Technical field
The present invention relates to a kind of elevator car safeties, and in particular to a kind of elevator governor.
Background technology
Existing elevator speed-limiting protective device is all brake apparatus safety tongs to be driven to act by limiter of speed, subtracts elevator
Speed stops.Limiter of speed includes rope sheave, around hanging with the steel wire rope that is connect with lift car on rope sheave, so as to make governor sheave can be with
It is rotated with speed corresponding with the speed of car.Steel wire rope connection safety tongs on rope sheave.When the rotary speed of governor sheave
During more than certain speed, centrifugal block for clutch use on governor sheave by means of rope sheave rotate caused by centrifugal force rotate, band running rope
Claw and pawl action on wheel make the cord-pressing block in the pressure rope component on limiter of speed compress steel wire rope, and steel wire rope is braked, and is limited
Fast device rope sheave stops operating, so as to make elevator out of service using the action of the wire rope pulling safety tongs of tensioning.
All it is that centrifugal-block or centrifugation bar are pulled using spring in existing elevator governor, but spring is being used for multiple times
Or it is prolonged place after elasticity can change, ratchet does not engage or rope sheave speed with ratchet when causing to occur accident
It does not exceed the speed limit also and has just released centrifugation bar or centrifugal-block.
Invention content
Based on this, in view of the above-mentioned problems, it is necessary to propose a kind of elevator governor, self-lock mechanism is used, with self-locking
Hydraulic stem connection centrifugation bar and mobile jib, when centrifugation bar is thrown away, self-locking hydraulic stem is elongated to just self-locking after certain length, makes centrifugation bar
On ratchet steadily mesh ratchet gear, solve the problems, such as spring itself inevitably elastic failure.
The technical scheme is that:
A kind of elevator governor, including rope sheave component, rack and the ratchet being fixedly connected with rack, the rope sheave component packet
Rope sheave, centrifugation bar and mobile jib are included, the center of rope sheave is fixedly mounted in the middle part of the mobile jib, the rope sheave is mounted on by bearing
In rack, the rope sheave and ratchet are concentric;The both ends of the mobile jib are respectively articulated with the centrifugation bar described in one, and rope sheave center two
A self-locking hydraulic stem, the middle part of the other end connection centrifugation bar of self-locking hydraulic stem, the centrifugation are connected on the mobile jib of side respectively
End of the bar far from mobile jib corresponds to ratchet and is fixedly connected with ratchet.
The operation principle of the present invention is:The steel wire rope of connection elevator is around on rope sheave, and rope sheave is rotated with steel wire rope, when
When elevator is declined with abnormal speed, the speed of rope sheave rotation is accelerated, and centrifuges the centrifugal force suffered by bar and increases, drives self-locking liquid
Compression bar extends self-locking, and the length of self-locking hydraulic stem will not change again at this time, ratchet just being engaged with ratchet, then coordinate steadily
Safety tongs action makes elevator out of service.
Mobile jib is equipped with the fastening screw for fixing mobile jib with centrifugation bar hinged place in one of the embodiments,.
The ratchet is removably to connect with centrifugation bar in one of the embodiments,.
Preferably, the ratchet is connect or is riveted by bolt and nut with centrifugation bar.
Preferably, the setting angle of the ratchet and centrifugation bar are in 30-75 degree.
In one of the embodiments, weight is additionally provided with close to that one end of ratchet on the centrifugation bar.
The weight is bloom or lead in one of the embodiments,.
Preferably, the weight at least sets two pieces.
Preferably, the ratchet uses chrome molybdenum silico-manganese steel.
Key, the mobile jib are machined on the sheave shaft that the center both sides of rope sheave are fixedly connected in one of the embodiments,
Middle through-hole in be machined with corresponding keyway.
The beneficial effects of the invention are as follows:
1st, using self-lock mechanism, centrifugation bar and mobile jib are connected with self-locking hydraulic stem, is thrown away when centrifuging bar, self-locking hydraulic stem
Just self-locking after certain length is elongated to, makes ratchet on centrifugation bar steadily mesh ratchet gear, it is inevitable to solve spring itself
Elastic failure problem, the work for making limiter of speed is relatively reliable, stablizes.
2nd, mobile jib makes mobile jib not generate rotation, causes with centrifugation bar hinged place equipped with the fastening screw for fixing mobile jib
Centrifugal force is made all to act on centrifugation bar, enhances trigger sensitivity.
3rd, ratchet is convenient for changing maintenance when ratchet is worn with centrifugation bar removably to connect.
4th, ratchet is connect or is riveted by bolt and nut with centrifugation bar, and maintenance is convenient for changing when ratchet is worn.
5th, the setting angle of ratchet makes ratchet more be consolidated when being engaged with ratchet firm with centrifugation bar in 30-75 degree.
6th, it centrifuges and is additionally provided with weight close to that one end of ratchet on bar, enhancing centrifuges the centrifugal force on bar, enhances tactile
Send out sensitivity.
7th, the weight be bloom or lead, it is interior in a limited space, use small weight big bloom or lead
Block centrifuges the centrifugal force of bar to enhance, and ensures trigger sensitivity.
8th, the weight at least sets two pieces, ensures that centrifugation bar by enough centrifugal force, makes trigger sensitivity higher.
9th, ratchet uses chrome molybdenum silico-manganese steel, ensure that the wearability and corrosion resistance of ratchet, effective ratchet avoids ratchet
Surface generates spot corrosion and crackle, enhances the service life of ratchet, while ensure that the reliability of elevator governor work.
10th, key is machined on the sheave shaft that the center both sides of rope sheave are fixedly connected, is processed in the middle through-hole of the mobile jib
There is corresponding keyway, when ratchet is engaged with ratchet, enhance the brake force to rope sheave, the performance for making limiter of speed is relatively reliable.
