Description
Technical field
The present invention relates to a kind of elevator car safety is and in particular to a kind of elevator governor.
Background technology
Existing elevator speed-limiting protective device is all to drive brake apparatus safety tongs action by limiter of speed, so that elevator is subtracted
Speed stops.Limiter of speed includes rope sheave, around hanging with the steel wire rope being connected with lift car on rope sheave, so that governor sheave is permissible
With speed corresponding with the speed of car rotation.Steel wire rope on rope sheave connects safety tongs.Rotary speed when governor sheave
When exceeding certain speed, the centrifugal block for clutch use on governor sheave is rotated by means of centrifugal force produced by rope sheave rotation, carries running rope
Paw on wheel and pawl action, make the cord-pressing block in the pressure rope part on limiter of speed compress steel wire rope, steel wire rope is braked, limit
Fast device rope sheave stops operating, thus making elevator out of service using the wire rope pulling safety tongs action of tensioning.
It is all that centrifugal-block or centrifugation bar are pulled using spring in existing elevator governor, but spring is being used for multiple times
Or after long placement, elasticity can change, and cause to occur ratchet during accident and do not engage with ratchet, or rope sheave speed
Also do not exceed the speed limit and just released centrifugation bar or centrifugal-block；
Secondly it is sometimes necessary to during elevator emergency brake, people can only press button nearby to stop, and first goes to observe electricity
Ladder display screen display is located floor now, then goes to press floor below button, and when elevator runs, the distance one of Stall is dodged
And mistake, have little time observe display screen on reading go again by floor button.
Content of the invention
Based on this, for the problems referred to above it is necessary to propose a kind of elevator governor, it adopts self-lock mechanism, with self-locking
Hydraulic stem, self-locking hydraulic stem is elongated to just self-locking after certain length, makes the ratchet steadily mesh ratchet gear on centrifugation bar, adopts simultaneously
Hydraulic controller controls self-locking hydraulic stem, can active control hydraulic stem flexible.
The technical scheme is that：
A kind of elevator governor, including rope sheave part, frame and the ratchet being fixedly connected with frame, described rope sheave part bag
Include rope sheave, the mobile jib being arranged on rope sheave center, centrifugation bar and self-locking hydraulic stem, the center two ends of described rope sheave are fixedly welded with flower
Key axle, described rope sheave is arranged in frame by bearing, and described rope sheave is concentric with ratchet, and described mobile jib centre bore is provided with and spline
The corresponding spline of axle, the two ends of described mobile jib are respectively articulated with the centrifugation bar described in, and the mobile jib of rope sheave center both sides
A upper piece self-locking hydraulic stem of connection respectively, the other end of self-locking hydraulic stem connects the middle part of centrifugation bar, and described mobile jib is provided with liquid
Pressure controller, hydraulic controller connects the hydraulic cylinder of self-locking hydraulic stem, and described hydraulic controller input wirelessly connects peripheral hardware control
Button processed, the corresponding ratchet in end of described centrifugation bar is fixedly connected with ratchet.
The operation principle of the present invention is：The steel wire rope connecting elevator is around on rope sheave, and rope sheave rotates with steel wire rope, when
When elevator is declined with abnormal speed, the speed that rope sheave rotates is accelerated, and the centrifugal force suffered by centrifugation bar increases, and orders about self-locking liquid
Depression bar extends self-locking, and now the length of self-locking hydraulic stem will not change again, ratchet just engaging with ratchet steadily, or
When in emergency circumstances, make hydraulic controller control self-locking hydraulic stem to extend self-locking by pressing peripheral hardware control button, cause elevator
Stop.
Wherein in an embodiment, mobile jib is provided with the fastening screw for fixing mobile jib with centrifugation bar hinged place.
Wherein in an embodiment, during described self-locking hydraulic stem self-locking, the active length of mobile jib and centrifugation bar is not shorter than
The internal diameter of ratchet.
Wherein in an embodiment, described self-locking hydraulic stem is inside mobile jib and centrifugation bar.
Wherein in an embodiment, described ratchet is dismountable connection with centrifugation bar.
Preferably, described ratchet is connected by bolt and nut with centrifugation bar or rivets.
Wherein in an embodiment, described centrifugation bar is additionally provided with weight near that one end of ratchet.
Wherein in an embodiment, described weight is bloom or lead.
Preferably, described ratchet adopts chrome molybdenum silico-manganese steel.
Wherein in an embodiment, the pitch diameter of described rope sheave is less than or equal to 220MM.
The invention has the beneficial effects as follows：
1st, adopt self-lock mechanism, connect centrifugation bar and mobile jib with self-locking hydraulic stem, when centrifugation bar throws away, self-locking hydraulic stem
It is elongated to just self-locking after certain length, and when in case of emergency, also the elongation of self-locking hydraulic stem can be controlled by hydraulic controller
Self-locking, makes the ratchet steadily mesh ratchet gear on centrifugation bar, solves spring itself using self-locking hydraulic stem inevitably elastic
Exhaustion problem, makes the work of limiter of speed relatively reliable, stable.
2nd, mobile jib and centrifugation bar hinged place are provided with the fastening screw for fixing mobile jib, make mobile jib will not produce rotation, cause
So that centrifugal force is all acted on centrifugation bar, enhance trigger sensitivity.
3rd, during the self-locking of self-locking hydraulic stem, the active length of mobile jib and centrifugation bar is not shorter than the internal diameter of ratchet it is ensured that ratchet energy
Engage with ratchet.
4th, self-locking hydraulic stem, inside mobile jib and centrifugation bar, simplifies and also strengthens master while limiter of speed internal structure
Bar and the intensity of centrifugation bar.
5th, ratchet and centrifugation bar are dismountable connection, are convenient for changing maintenance when ratchet weares and teares.
6th, ratchet is connected by bolt and nut with centrifugation bar or rivets, and is convenient for changing maintenance when ratchet weares and teares.
7th, it is additionally provided with weight near that one end of ratchet on centrifugation bar, strengthen the centrifugal force on centrifugation bar, enhance tactile
Send out sensitivity.
8th, described weight is bloom or lead, in limited space, using the big bloom of small volume weight or lead
Block is strengthening the centrifugal force of centrifugation bar it is ensured that trigger sensitivity.
9th, ratchet adopts chrome molybdenum silico-manganese steel it is ensured that the wearability of ratchet and corrosion resistance, and effective ratchet avoids ratchet
Surface produces spot corrosion and crackle, enhances the service life of ratchet, ensure that the reliability of elevator governor work simultaneously.
10th, the pitch diameter of described rope sheave is less than or equal to 220MM, is reducing the volume of elevator governor, is reducing into
This while, is it is ensured that rope sheave can have enough centrifugal force to drive the elongation of self-locking hydraulic stem self-locking under identical linear velocity.
