Description
Technical field
The present invention relates to a kind of elevator car safety, and in particular to a kind of elevator governor.
Background technology
Existing elevator speed-limiting protective device is all to drive brake unit safety tongs action by limiter of speed, subtracts elevator
Speed stops.Limiter of speed includes rope sheave, around hanging with the steel wire rope that is connected with lift car on rope sheave, so that governor sheave can be with
With speed corresponding with the speed of car rotation.Steel wire rope attachment security pincers on rope sheave.When the rotary speed of governor sheave
During more than certain speed, the centrifugal block for clutch use on governor sheave is rotated by means of the centrifugal force produced by rope sheave rotation, band running rope
Paw and pawl action on wheel, makes the cord-pressing block in the pressure rope part on limiter of speed compress steel wire rope, and steel wire rope is braked, and limits
Fast device rope sheave stops operating, so as to make elevator out of service using the wire rope pulling safety tongs action 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 elasticity can change after prolonged placement, ratchet is not engaged with ratchet when causing to occur accident, 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 remove observation electricity
Ladder shows that 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.
The 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 after certain length just self-locking, makes ratchet on centrifugation bar steadily mesh ratchet gear, while using
Hydraulic controller controls self-locking hydraulic stem, can active control hydraulic stem it is flexible.
The technical scheme is that：
A kind of elevator governor, including rope sheave part, frame and the ratchet that is fixedly connected with frame, the rope sheave part bag
Mobile jib, centrifugation bar and the self-locking hydraulic stem for include rope sheave, being arranged on rope sheave center, the center two ends of the rope sheave are fixedly welded with flower
Key axle, the rope sheave is arranged in frame by bearing, and the rope sheave is concentric with ratchet, and the mobile jib centre bore is provided with and spline
The corresponding spline of axle, the two ends of the mobile jib are respectively articulated with the centrifugation bar described in, and the mobile jib of rope sheave center both sides
Upper to connect a self-locking hydraulic stem respectively, the middle part of the other end connection centrifugation bar of self-locking hydraulic stem, the mobile jib is provided with liquid
Pressure controller, hydraulic controller connects the hydraulic cylinder of self-locking hydraulic stem, and the hydraulic controller input wirelessly connects peripheral hardware control
Button processed, the end correspondence ratchet of the centrifugation bar is fixedly connected with ratchet.
The present invention operation principle be：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 that rope sheave is rotated is accelerated, and the centrifugal force suffered by bar is centrifuged and 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, Huo Zhe
When in emergency circumstances, make hydraulic controller control the elongation self-locking of self-locking hydraulic stem by pressing peripheral hardware control knob, cause elevator
Stop.
Wherein in one embodiment, mobile jib is provided with the fastening screw for fixing mobile jib with centrifugation bar hinged place.
Wherein in one embodiment, during the 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 one embodiment, the self-locking hydraulic stem is inside mobile jib and centrifugation bar.
Wherein in one embodiment, the ratchet is removably to be connected with centrifugation bar.
Preferably, the ratchet is connected by bolt and nut or is riveted with centrifugation bar.
Wherein in one embodiment, weight is additionally provided near that one end of ratchet on the centrifugation bar.
Wherein in one embodiment, the weight is bloom or lead.
Preferably, the ratchet adopts chrome molybdenum silico-manganese steel.
Wherein in one embodiment, the pitch diameter of the rope sheave is less than or equal to 220MM.
The invention has the beneficial effects as follows：
1st, self-lock mechanism is adopted, with self-locking hydraulic stem connection centrifugation bar and mobile jib, when centrifugation bar throws away, self-locking hydraulic stem
Just self-locking is elongated to 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 ratchet on centrifugation bar steadily mesh ratchet gear, and using self-locking hydraulic stem the inevitable elasticity of spring itself is solved
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 not produce rotation, cause
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 also strengthens master inside mobile jib and centrifugation bar while simplifying limiter of speed internal structure
The intensity of bar and centrifugation bar.
5th, ratchet is convenient for changing maintenance when ratchet weares and teares with centrifugation bar to be removably connected.
6th, ratchet is connected by bolt and nut or is riveted with centrifugation bar, and maintenance is convenient for changing when ratchet weares and teares.
7th, it is centrifuged on bar and is additionally provided with weight near that one end of ratchet, strengthen the centrifugal force on centrifugation bar, enhances tactile
Send out sensitivity.
8th, the weight is bloom or lead, in limited space, using the big bloom of small volume weight or lead
Block is centrifuged the centrifugal force of bar to strengthen, it is ensured that trigger sensitivity.
9th, ratchet adopts chrome molybdenum silico-manganese steel, it is ensured that the wearability and corrosion resistance of ratchet, effective ratchet avoids ratchet
Surface produces spot corrosion and crackle, enhances the service life of ratchet, while ensure that the reliability that elevator governor works.
10th, the pitch diameter of the rope sheave is less than or equal to 220MM, is reducing the volume of elevator governor, reduces into
This while, it is ensured that rope sheave can have enough centrifugal force to drive the elongation of self-locking hydraulic stem and self-locking under identical linear velocity.
