Embodiment Construction

[0033] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0034] like Figure 1 to Figure 17In one embodiment of the elevator emergency braking device of the present invention shown, the elevator emergency braking device includes an elevator lower beam 10, and the two sides of the elevator lower beam 10 are respectively equipped with safety gears 20 that cooperate with the elevator guide rails. The beam 10 is also equipped with a linkage mechanism for driving the safety gear 20 on both sides of the lower beam 10 of the elevator to move synchronously. The linkage mechanism includes a fixed plate 31, a linkage shaft 32 and a rocker arm 33. On both sides of the lower beam 10 of the elevator, the fixing plate 31 is provided with mounting holes 311 for installing...

Abstract

The invention relates to an elevator emergency braking device, which comprises an elevator underbeam and safety tongs. A linkage mechanism is further arranged on the elevator underbeam and comprises fixing plates, a linkage shaft and a rocker arm; one end of the rocker arm is connected with the safety tongs; a lifting stopping shaft connected with a steel wire rope of a speed governor is arrangedon the other end of the rocker arm; a reset plate is arranged on the lifting stopping shaft; a reset through hole is formed in the reset plate; spring fixing seats are further arranged on the fixing plates; a core shaft penetrating through the reset through hole is arranged on the spring fixing seats; two reset springs located on two sides of the reset plate sleeve the core shaft; one ends of thereset springs press against the reset plate; and the other ends of the reset springs press against the spring fixing seats. According to the elevator emergency braking device provided by the invention, with the linkage mechanism, two swing arms can be ensured to rotate synchronously so as to drive the safety tongs on two sides of the elevator underbeam to brake synchronously, so that an elevator car is prevented from inclining during an emergency braking process; and after the braking is relieved, the reset springs on the core shaft can drive the swing arms to reset, so that the safety tongs loosens guide rails.

Description

technical field [0001] The invention relates to elevator safety control technology, in particular to an elevator emergency braking device. Background technique [0002] The safety gear is an important safety component of the elevator equipment. It can play a role in safety protection when the elevator overspeeds or stalls. The action of the safety gear device is to make the rope clamp clamp the speed limiter rope through the action of the speed limiter, and then go down with the car. Running, the speed limiter rope pulls the safety gear linkage mechanism, and the safety gear linkage mechanism moves to drive the safety gear braking element to contact the guide rail, so that the safety gear on both sides of the guide rail is tightened on the guide rail at the same time, so that the car is stopped. In order to ensure the synchronous action of the safety gear on both sides of the elevator car, a safety gear linkage device is usually provided to realize the synchronous braking of...
