Description
Technical field
The present invention relates to a kind of limiter of speed safety tongs shift mechanism for saving ele-vator shaft spaces, this kind of shift mechanism structures
Simply, space is saved, is particularly suitable for hoistway space limited elevator and oblique elevator.
Background technology
Limiter of speed, safety tongs are one of important safety components of elevator, play overspeed protection in elevator operation.It is existing
In technology, limiter of speed plays supervisory function bit to the speed of car, plays tensioner to speed limiter wire rope by weight swelling device,
Speed limiter wire rope is connected with the fag end knob in safety tongs shift mechanism, and safety tongs shift mechanism is installed on elevator car rack
It is moved with car, when elevator runs and exceeds the speed limit, limiter of speed clamping speed limiter wire rope, speed limiter wire rope stop motion, safety
Pincers shift mechanism is moved with car, and speed limiter wire rope pulls the fag end knob in safety tongs shift mechanism, and lifting safety tongs moves
Make, make car stop.Therefore, in the case where hoistway space is very limited, particularly when the pit space of hoistway is very narrow
When or in oblique elevator hoistway, speed limiter wire rope around when there may be the risk interfered between speed limiter wire rope, and
The weight of conventional swelling device is mostly swing arm, occupies pit space and plane is larger, the lifting of this type limiter of speed safety tongs
Mechanism will be very restricted, and can greatly increase the difficulty of elevator structure arrangement, in some instances it may even be possible to can be rational because that can not carry out
Structure arranges and cannot install elevator.
Invention content
To overcome above-mentioned the shortcomings of the prior art, the technical problem to be solved by the present invention is to by limiter of speed and weight
Swelling device is arranged with a kind of new way, is achieved the purpose that reliable speed limit and is fully saved ele-vator shaft spaces.
The technical solution for solving present invention problem is as described below：
A kind of limiter of speed safety tongs shift mechanism for saving ele-vator shaft spaces, the shift mechanism include limiter of speed, limit
Fast device steel wire rope, safety tongs, safety tongs pull rod, safety tongs linkage mechanism connecting rod, it is characterised in that：The limiter of speed is arranged on
In car assembly, limiter of speed bottom connection limiter of speed mounting base, shaft is fixed on car frame upper beam, the limiter of speed mounting base
Pivot pair is formed with shaft, limiter of speed can rotate around the axis；Safety tongs pull rod one end is connect with limiter of speed, the other end and peace
Full pincers linkage mechanism connecting rod connection, safety tongs linkage mechanism connecting rod and safe clipper joint, described speed limiter wire rope one end is consolidated
Due to well headroom, which is directed to elevator shaft bottom through guider, with being arranged on elevator
The swelling device of road bottom connects and by the swelling device tensioner.When elevator runs hypervelocity downwards, limiter of speed action, limiter of speed
Rope sheave card resistance does not rotate, and speed limiter wire rope is static with respect to governor sheave, and limiter of speed entirety is in speed limiter wire rope to rope sheave
Under frictional force effect, be rotated up lifting around the shaft, the rotating torque that when action generates lifts safety tongs, safety tongs voussoir to
Guide rail, car assembly stop are blocked in upper action, self-locking；Limiter of speed triggers safety switch, safety switch while being rotated up
Action, the power supply of cut-out driving host, driving host shut down.
Elevator governor safety tongs shift mechanism provided by the invention is further characterized in that：The guider
Including directive wheel I, directive wheel II, directive wheel III, directive wheel IV, directive wheel I on car frame upper beam, install by directive wheel II
In car frame vertical beam, I-directive wheel of directive wheel IV can be freely rotated in itself；The rope of the directive wheel I and the rope sheave of directive wheel II
Slot is in same vertical guide, and speed limiter wire rope is around directive wheel I, governor sheave and directive wheel II, speed limiter wire rope
Cornerite during around governor sheave is more than cornerite as defined in the limiter of speed, during ensureing limiter of speed action, speed limiter wire rope
It is non-slip on limiter of speed；The directive wheel III, directive wheel IV are respectively arranged in elevator shaft bottom, and the lower edge of the directive wheel IV must
Pit ground must be higher by, which need to be higher by the shaft height of directive wheel IV and ensure that swelling device is not born；Limit
Fast device steel wire rope from directive wheel II around rope outlet groove when with directive wheel IV around entering grooving in same vertical guide, speed limiter wire rope from
When directive wheel IV is around rope outlet groove with around entering III grooving of directive wheel in same vertical guide.The limiter of speed being fixed at the top of elevator shaft
Steel wire rope is directed to elevator shaft bottom through directive wheel I, governor sheave, directive wheel II and directive wheel IV, directive wheel III,
It is connect with the swelling device for being arranged on elevator shaft bottom and by the swelling device tensioner.
The swelling device uses counterweight tensioner.
Limiting plate is installed in I mounting seat of directive wheel, and microswitch is mounted on limiting plate, circuit series connection access peace
Full loop, resetting spring both ends are separately fixed on limiting plate and limiter of speed.For conventional structure, this programme, which increases limiting plate, to be prevented
Only safety tongs operation time limit speed device rotational angle is excessive, locked to reset；Increase resetting spring, brake and unlock in safety tongs
Afterwards, spring compression force can make limiter of speed return to normal operation position, and can also prevent because of elevator in normal course of operation
The reasons such as operation vibrations cause elevator safety gear to malfunction.
The limiter of speed safety tongs shift mechanism provided by the invention for saving ele-vator shaft spaces is after installation is complete, limiter of speed with
Directive wheel I, directive wheel II are run up and down with car, an only speed limiter wire rope by swelling device tensioner, around
Governor sheave is crossed, for monitoring the speed of car.When car speed overrate, limiter of speed is blocked in limiter of speed action
Steel wire rope, car continue to move, and drive limiter of speed rotation, and limiter of speed rotation drives safety tongs shift mechanism to act, stop car,
Limiter of speed rotation acts on electric switch simultaneously, and traction machine is made to stop operating, plays the role of overspeed protection.
Limiter of speed safety tongs shift mechanism provided by the invention, simple in structure, function is reliable, limiter of speed is transported mounted on car
It is moved on kinetoplast with car, the rotating torque generated when being acted by limiter of speed lifts safety tongs, single limiter of speed steel
Cord one is fixed on well headroom, and one is fixed on well pit bottom, and using weight tensioner, steel wire rope is for hoistway without phase
To movement.It is rotated relative to traditional speed limiter wire rope around governor sheave and expansion tightening wheel, hoistway space can be greatlyd save.
In diagonal hoistway, single speed limiter wire rope can effectively avoid the interference risk generated when surrounding between speed limiter wire rope.It should
Mechanism application range is very extensive, available for various types of elevators, cannot be only used for the elevator with general hoistway space, especially
It can be used for the elevator with narrow hoistway space or even originally because the hoistway that space limitation can not install elevator can install electricity
Ladder.
