Abstract
The utility model discloses an accidental movement protective system of an elevator car. The accidental movement protective system comprises a bidirectional safety gear and a bidirectional speed governor, wherein a governor rope of the bidirectional speed governor is moved to drive the speed governor to rotate when the elevator car moves; and the safety gear is lifted by the governor rope to brake the elevator car. The accidental movement protective system of the elevator car further comprises a clamping device, wherein the clamping device comprises a swinging arm, a swinging wheel and a spring; a ratchet wheel is arranged on the speed governor; the swinging arm and the swinging wheel respectively press the two sides of the ratchet wheel; the swinging arm and the swinging wheel can clamp the ratchet wheel under the action of elastic force of the spring; when the elevator car has accidental movement, the clamping device is used for clamping the ratchet wheel by the swinging arm and the swinging wheel, so that the speed governor stops rotating and further the accidental movement of the elevator bar is braked. The ratchet wheel is clamped by the clamping device so as to clamp the speed governor, so that the elevator car cannot move in two directions. Meanwhile, when the door of the elevator is open, an electromagnetic control circuit is used for controlling the clamping device by virtue of the magnet action so as to brake the bidirectional accidental movement of the elevator car; therefore, the realtime performance is strong, the brake speed is high and the reliability is high.
Description
Technical field
The utility model relates to the elevator field, particularly a kind of car accidental movement protection system.
Background technology
Along with the development of urbanization, the quantity of elevator sharply increases, and the safety of elevator becomes the focus that people pay close attention to.Some elevator accident is lift car mobile the causing that meet accident under the state of door-opened elevator.The elevator majority of prior art is by wire holder, governor rope to be clamped and made the lift car braking, but, in the elevator that period of service is grown, becomes smooth because governor rope is subject to clamping friction for a long time, and brake efficiency is poor, and the braking reliability reduces.
The utility model content
The utility model is in order to overcome defect in above-mentioned prior art, by ratchet and gripping mechanism thereof are set on velocity limiter, and control by electromagnetic control circuit, by velocity limiter-safety tongs linked system, as actuating unit, improved the braking reliability of accidental movement of elevator cage.
For achieving the above object, the utility model provides a kind of accidental movement of elevator cage protection system, comprise bidirectional safety tongs and bidirectional speed limiter, the movement of lift car causes the movement of the governor rope on velocity limiter, and then the drive velocity limiter rotates, governor rope lifts safety tongs and makes the lift car braking, also comprises: gripping mechanism, and it comprises swing arm, wabble wheel and spring; Velocity limiter is provided with ratchet, and swing arm and wabble wheel are pressed on respectively the both sides of ratchet, and swing arm and wabble wheel are subjected to the elastic force of spring and keep the chucking to ratchet; At lift car, meet accident when mobile, gripping mechanism stops the rotation velocity limiter by swing arm and wabble wheel chucking ratchet, and then the accidental movement of braking lift car.By gripping mechanism, the ratchet on velocity limiter is compressed and blocks velocity limiter, make car braking by velocity limiter-safety tongs link gear, for the reliable braking of accidental movement of elevator cage provides another kind of guarantee.
In technique scheme, a side of wabble wheel is provided with action magnet, and action magnet obtains electric under elevator parking and door opening state, and controls swing arm and wabble wheel chucking ratchet, makes system in running order.The control of magnet makes the reliability of velocity limiter monitoring accidental movement of elevator cage under the door-opened elevator state improve.
In technique scheme, action magnet is subjected to the control of electromagnetic control circuit.Electromagnetic control circuit makes whole protection system reach the effect of real-time reliably monitoring, has improved the reliability of system.
The accompanying drawing explanation
Fig. 1 is velocity limiter schematic diagram of the present utility model;
Fig. 2 is the electromagnetic control circuit schematic diagram.
Mark the following drawings mark thereon by reference to the accompanying drawings:
1-bidirectional speed limiter, 11-ratchet, 2-gripping mechanism, 21-swing arm, 22-wabble wheel, 23-spring, 3-move magnet.
The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
As shown in Figure 1, the body of bidirectional speed limiter 1 of the present utility model is provided with the ratchet 11 with four protrusions.The body of bidirectional speed limiter 1 is provided with the race that governor rope is installed, the mobile movement that drives governor rope of car, and then the rotation of drive bidirectional speed limiter, governor rope is connected with the bidirectional safety tongs (not shown), and governor rope makes the lift car braking by lifting bidirectional safety tongs.
A side at wabble wheel 22 is provided with action magnet 3, and action magnet 3 is subjected to the control of electromagnetic control circuit and moves.Under elevator parking door opening state, electromagnetic control circuit is by the accidental movement (way moving up or down) of the swing monitoring lift car of swing arm 21.The way moving of lift car causes the bidirectional rotation of bidirectional speed limiter and the way moving of safety tongs.
As shown in Figure 2, elevator is under parking door opening state, door lock closes the contacting of monitoring contactless switch (KDL), and the closing of contact of two band-type brake contactless switch KBK1 and KBK2, circuit is connected, and now car accidental movement monitoring magnet obtains electric, action magnet 3 obtains electric, make wabble wheel 22 be clamped on the ratchet 11 of bidirectional speed limiter 1, thereby block bidirectional speed limiter 1, prevent bidirectional speed limiter 1 rotation.
When lift car meets accident when mobile, the swing arm 21 of gripping mechanism 2 and 22 pairs of ratchets of wabble wheel 11 form clamping force on the one hand, on the other hand, the friction force of governor rope and bidirectional speed limiter lifts the safety tongs that moves or move down, make the lift car that moves or move down on the safety tongs forced brake, the braking reliability while having improved the two-way accidental movement of lift car.
The gripping mechanism formed by swing arm and wabble wheel compresses and blocks bidirectional speed limiter the ratchet on bidirectional speed limiter, plays the effect that prevents the lift car way moving.Simultaneously, under the door-opened elevator state, electromagnetic control circuit is by the swing monitoring accidental movement of elevator cage of swing arm, and by the accidental movement of magnet action control gripping mechanism braking lift car, real-time, retro-speed is fast, and reliability is high.
Above disclosed be only a specific embodiment of the present utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
