Description
Technical field
This utility model relates to a kind of limiter of speed safety tongs shift mechanism saving ele-vator shaft spaces, this kind of shift mechanism
Simple in construction, saving space, be particularly suited for the limited elevator of hoistway space and oblique elevator.
Background technology
Limiter of speed, safety tongs are one of important safety parts of elevator, play overspeed protection effect in elevator runs.Existing
In technology, the speed of car is played supervisory function bit by limiter of speed, by weight swelling device, speed limiter wire rope plays tensioner effect,
Speed limiter wire rope shakes hands to be connected with the fag end in safety tongs shift mechanism, and safety tongs shift mechanism is installed on elevator car rack
Move with car, when elevator runs hypervelocity, limiter of speed clamping speed limiter wire rope, speed limiter wire rope stop motion, safety
Pincers shift mechanism moves with car, and speed limiter wire rope pulls the fag end in safety tongs shift mechanism to shake hands, and lifting safety tongs moves
Make, make car stop.Therefore, in the case of hoistway space is very limited, particularly the narrowest and small when the pit space of hoistway
Time or in oblique elevator hoistway, there may be during speed limiter wire rope cincture between speed limiter wire rope interfere risk, and
The weight of conventional swelling device mostly is swing arm, takies pit space and plane is relatively big, and this type limiter of speed safety tongs lifts
Mechanism will be very restricted, and can be greatly increased the difficulty that elevator structure is arranged, in some instances it may even be possible to can be because cannot be carried out reasonably
Structure is arranged and can not be installed elevator.
Summary of the invention
For the deficiency overcoming above-mentioned prior art to exist, the technical problems to be solved in the utility model is, by limiter of speed and
Weight swelling device is arranged with a kind of new way, reaches reliable speed limit and fully saves the purpose of ele-vator shaft spaces.
The technical scheme solving this utility model technical problem is as described below:
A kind of limiter of speed safety tongs shift mechanism saving ele-vator shaft spaces, described shift mechanism includes limiter of speed, limit
Speed device steel wire rope, safety tongs, safety tongs pull bar, safety tongs link gear connecting rod, it is characterised in that: described limiter of speed is arranged on
In car assembly, connecting limiter of speed mounting seat bottom this limiter of speed, rotating shaft is fixed on car frame upper beam, this limiter of speed mounting seat
Constituting pivot pair with rotating shaft, limiter of speed can rotate around the axis；Safety tongs pull bar one end is connected with limiter of speed, the other end and peace
Full pincers link gear connecting rod connects, and safety tongs link gear connecting rod is connected with safety tongs, and described speed limiter wire rope one end is solid
Due to well headroom, this speed limiter wire rope other end is directed to bottom elevator hoistways through guider, and is arranged on elevator
Swelling device bottom road connects and by this swelling device tensioner.When elevator runs hypervelocity downwards, limiter of speed action, limiter of speed
Rope sheave jam does not rotates, and speed limiter wire rope is static relative to governor sheave, limiter of speed overall at speed limiter wire rope to rope sheave
Under frictional force effect, around the shaft be rotated up lifting, during action produce rotating torque lift safety tongs, safety tongs voussoir to
Upper action, guide rail, car assembly stop are blocked in self-locking；Limiter of speed, while being rotated up, triggers safety switch, safety switch
Action, cuts off the power supply of driving host, and driving host shuts down.
This utility model provide elevator governor safety tongs shift mechanism be further characterized in that described guiding
Device includes directive wheel I, directive wheel II, directive wheel III, directive wheel IV, and directive wheel I is arranged on car frame upper beam, directive wheel
II is arranged in car frame vertical beam, and directive wheel I-directive wheel IV itself can be freely rotatable；This directive wheel I and the rope of directive wheel II
The grooving of wheel is in same vertical guide, and speed limiter wire rope walks around directive wheel I, governor sheave and directive wheel II, limiter of speed
The cornerite that cornerite when governor sheave walked around by steel wire rope specifies more than this limiter of speed, during to ensure limiter of speed action, limiter of speed
Steel wire rope is non-slip on limiter of speed；This directive wheel III, directive wheel IV are respectively arranged in bottom elevator hoistways, this directive wheel IV
Lower edge must exceed pit ground, and this directive wheel III lower edge need to exceed the rotating shaft height of directive wheel IV and ensure that swelling device does not falls
Ground；Speed limiter wire rope from directive wheel II around rope outlet groove time with directive wheel IV around entering grooving in same vertical guide, limiter of speed steel
Cord from directive wheel IV around rope outlet groove time with around entering directive wheel III grooving in same vertical guide.It is fixed on elevator hoistways top
Speed limiter wire rope is directed to elevator through this directive wheel I, governor sheave, directive wheel II and directive wheel IV, directive wheel III
Bottom road, it is connected with the described swelling device being arranged on bottom elevator hoistways and by this swelling device tensioner.
Described swelling device uses counterweight tensioner.
Limiting plate is installed in directive wheel I mounting seat, and microswitch is arranged on limiting plate, and its circuit connected in series accesses peace
Full loop, back-moving spring two ends are separately fixed on limiting plate and limiter of speed.For conventional structure, this programme increases limiting plate to be prevented
Only safety tongs operation time limit speed device rotational angle is excessive, locked cannot reset；Increase back-moving spring, unlock in safety tongs brake
After, spring compression force can make limiter of speed return to normal operation position, and also can prevent because of elevator in normal course of operation
Run the reasons such as vibrations and cause elevator safety gear misoperation.
After the limiter of speed safety tongs shift mechanism installation saving ele-vator shaft spaces that this utility model provides, speed limit
Device runs with car up and down with directive wheel I, directive wheel II, and an only speed limiter wire rope is risen by swelling device
Tightly, walk around governor sheave, for monitoring the speed of car.When car speed overrate, limiter of speed action, block limit
Speed device steel wire rope, car continues motion, drives limiter of speed to rotate, and limiter of speed rotates and drives safety tongs shift mechanism action, stop
Car, limiter of speed rotates and simultaneously acts on electric switch, makes traction machine stop operating, play the effect of overspeed protection.
The limiter of speed safety tongs shift mechanism that this utility model provides, simple in construction, function are reliable, and limiter of speed is arranged on sedan-chair
Move with car on the movable body of railway carriage or compartment, lift safety tongs, single speed limit by the rotating torque produced during limiter of speed action
One, device steel wire rope is fixed on well headroom, and one is fixed on bottom well pit, uses weight tensioner, and steel wire rope is for hoistway
Without relative motion.Rotate around governor sheave and expansion tightening wheel relative to tradition speed limiter wire rope, hoistway can be greatly saved empty
Between.In diagonal hoistway, single speed limiter wire rope produces the interference wind between speed limiter wire rope when can be prevented effectively from cincture
Danger.This mechanism's range of application widely, can be used for various types of elevator, cannot be only used for the electricity with general hoistway space
Ladder, is used especially for the elevator with narrow and small hoistway space, and because space limits, cannot to install the hoistway of elevator permissible even originally
Elevator is installed.
