Description
Technical field
The present invention 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.In prior art, the speed of car is played supervisory function bit by limiter of speed, by weight swelling device, speed limiter wire rope played tensioner effect, speed limiter wire rope shakes hands to be connected with the fag end in safety tongs shift mechanism, safety tongs shift mechanism is installed on elevator car rack and moves with car, when elevator runs hypervelocity, limiter of speed clamping speed limiter wire rope, speed limiter wire rope stop motion, safety tongs shift mechanism moves with car, speed limiter wire rope pulls the fag end in safety tongs shift mechanism to shake hands, and lifts safety tongs action, makes car stop.Therefore, in the case of hoistway space is very limited, particularly when the pit space of hoistway is the narrowest and small or in oblique elevator hoistway, the risk interfered between speed limiter wire rope is there may be during speed limiter wire rope cincture, and the weight of routine swelling device mostly is swing arm, take pit space and plane is bigger, this type limiter of speed safety tongs shift mechanism will be very restricted, the difficulty that elevator structure is arranged can be greatly increased, in some instances it may even be possible to can arrange because cannot be carried out rational structure and elevator can not be installed.
Summary of the invention
For the deficiency overcoming above-mentioned prior art to exist, the technical problem to be solved in the present invention is, limiter of speed and weight swelling device is arranged with a kind of new way, reaches reliable speed limit and fully save the purpose of ele-vator shaft spaces.
The technical scheme solving the technology of the present invention 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, speed limiter wire rope, safety tongs, safety tongs pull bar, safety tongs link gear connecting rod, it is characterized in that: described limiter of speed is arranged in car assembly, limiter of speed mounting seat is connected bottom this limiter of speed, rotating shaft is fixed on car frame upper beam, it is secondary that this limiter of speed mounting seat and rotating shaft constitute pivot, and limiter of speed can rotate around the axis；Safety tongs pull bar one end is connected with limiter of speed, the other end is connected with safety tongs link gear connecting rod, safety tongs link gear connecting rod is connected with safety tongs, well headroom is fixed in described speed limiter wire rope one end, this speed limiter wire rope other end is directed to bottom elevator hoistways through guider, is connected with the swelling device being arranged on bottom elevator hoistways and by this swelling device tensioner.When elevator runs hypervelocity downwards, limiter of speed action, governor sheave jam does not rotates, speed limiter wire rope is static relative to governor sheave, and limiter of speed entirety under rope sheave frictional force effect, is rotated up lifting at speed limiter wire rope around the shaft, the rotating torque produced during action lifts safety tongs, the upwards action of safety tongs voussoir, 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.
The present invention provide elevator governor safety tongs shift mechanism be further characterized in that described guider includes directive wheel I, directive wheel II, directive wheel III, directive wheel IV, 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；The grooving of the rope sheave of this directive wheel I and directive wheel II is in same vertical guide, and speed limiter wire rope walks around directive wheel I, governor sheave and directive wheel II, the cornerite that cornerite when speed limiter wire rope walks around governor sheave specifies more than this limiter of speed, during to ensure limiter of speed action, speed limiter wire rope is non-slip on limiter of speed；This directive wheel III, directive wheel IV are respectively arranged in bottom elevator hoistways, and the lower edge of this directive wheel IV 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 is the most born；Speed limiter wire rope from directive wheel II around rope outlet groove time with directive wheel IV around entering grooving in same vertical guide, speed limiter wire rope from directive wheel IV around rope outlet groove time with around entering directive wheel III grooving in same vertical guide.It is fixed on the speed limiter wire rope at elevator hoistways top through this directive wheel I, governor sheave, directive wheel II and directive wheel IV, directive wheel III are directed to bottom elevator hoistways, are 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 safety return circuit, and back-moving spring two ends are separately fixed on limiting plate and limiter of speed.For conventional structure, this programme increases limiting plate and prevents safety tongs operation time limit speed device rotational angle excessive, locked cannot reset；Increasing back-moving spring, after safety tongs brake unlocks, spring compression force can make limiter of speed return to normal operation position, and also can prevent to run the reasons such as vibrations because of elevator in normal course of operation and cause elevator safety gear misoperation.
After the limiter of speed safety tongs shift mechanism installation saving ele-vator shaft spaces that the present invention provides, limiter of speed runs with car up and down with directive wheel I, directive wheel II, an only speed limiter wire rope passes through swelling device tensioner, walks around governor sheave, for monitoring the speed of car.When car speed overrate; limiter of speed action; block speed limiter 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, plays the effect of overspeed protection.
The limiter of speed safety tongs shift mechanism that the present invention provides, simple in construction, function are reliable, limiter of speed is arranged on car movable body and moves with car, safety tongs is lifted by the rotating torque produced during limiter of speed action, single speed limiter wire rope one is fixed on well headroom, one is fixed on bottom well pit, use weight tensioner, steel wire rope for hoistway without relative motion.Rotate around governor sheave and expansion tightening wheel relative to tradition speed limiter wire rope, hoistway space can be greatly saved.In diagonal hoistway, single speed limiter wire rope produces the interference risk between speed limiter wire rope when can be prevented effectively from cincture.This mechanism's range of application widely, can be used for various types of elevator, cannot be only used for the elevator with general hoistway space, is used especially for the elevator with narrow and small hoistway space, even originally cannot install the hoistway of elevator can install elevator because space limits.
