Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, a safety catch system for an elevator includes a car 1 and guide rails 2, which are installed in a hoistway, and the guide rails 2 are installed at both sides of the hoistway, and the car 1 is installed between the two guide rails 2.

Install telescopic link 3 at car 1's bilateral symmetry, one on the other set up promptly, and the tip of every telescopic link 3 all is fixed with first voussoir 4, in this implementation, telescopic link 3 can adopt electric putter, arbitrary one among pneumatic putter or the hydraulic putter, and telescopic link 3's switch needs to install in car 1's inboard, make the passenger touch, set up position maximum point, can avoid children to miss effectively touch, then be provided with cavity 7 in car 1's both sides simultaneously, and telescopic link 3 then installs in cavity 7, can avoid telescopic link 3 direct and well internal environment direct contact like this, can have certain guard action to telescopic link 3, guarantee telescopic link 3's life.

All the butt has two second voussoirs 5 at 4 tip of every first voussoir, and the setting of two second voussoir 5 mirror images, the inclined plane all contacts with the inclined plane of first voussoir 4, and the another side then is fixed with speed reduction plate 6, and with integrated into one piece between the speed reduction plate 6, and then flexible setting between two speed reduction plate 6, it is concrete, be provided with between two speed reduction plate 6 and adjust pole 8, and the both ends of adjusting pole 8 all are fixed with stopper 9, there is sleeve 10 simultaneously in the both sides slidable mounting of adjusting pole 8, and the other end of sleeve 10 is then fixed on the speed reduction plate 6 that corresponds, and still be fixed with connecting rod 11 on adjusting pole 8, speed reduction plate 6 is fixed on car 1 through connecting rod 11 on adjusting pole 8.

The two speed-reducing plates 6 can slide on the adjusting rod 8 through the sleeve 10, and the limiting block 9 can limit the over-limit between the adjusting rod 8 and the sleeve 10.

Through the technical scheme, when the elevator appears falling, the falling speed of elevator can increase, general elevator speed is generally one to three meters per second, when the speed of the elevator that the passenger felt appears unusually, can directly press the switch of the interior telescopic link 3 of car 1, on-off control telescopic link 3 is flexible and drive first voussoir 4 and the extrusion of second voussoir 5, make and keep away from each other between two second voussoir 5, and drive the inner wall contact of air brake 6 and guide rail 2, and continuously exert pressure to the inner wall of guide rail 2, in order to increase frictional force between the two, and the area of contact between air brake 6 itself and guide rail 2 is also bigger for prior art, can further improve frictional force between the two, can effectual reduction braking distance, realize the speed reduction of elevator until stopping.

Therefore, when the speed of the elevator changes abnormally, the elevator can be operated to decelerate and stop in time by operating the system without waiting for the triggering condition of the safety gear, such as insufficient speed, no rope breakage and the like, so that the danger can be effectively prevented from further expanding.

When using, elevator normal operating's process car 1 drives the air brake 6 and removes in guide rail 2, and has certain limiting displacement between air brake 6 and the guide rail 2, can avoid jolting of car 1 when the motion, when the elevator falls suddenly, the passenger can in time press the button of telescopic link 3 in the car 1, in time order about the motion of telescopic link 3, make the first voussoir 4 and the contact extrusion of second voussoir 5 of 3 tip of telescopic link, and drive air brake 6 and the contact of guide rail 2 in the guide rail 2, slow down and stop the elevator.
