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 includes an elevator lower beam and a safety gear. A linkage mechanism is installed on the elevator lower beam. The linkage mechanism includes a fixing plate, a linkage shaft and a rocker arm. One end of the rocker arm is connected with the safety gear. The other end is installed with a lifting retaining shaft connected with the wire rope of the speed limiter; a reset plate is arranged on the lifting retaining shaft, and a reset through hole is arranged on the reset plate, and a spring fixing seat is also installed on the fixing plate, and the spring fixing seat There is a mandrel passing through the reset through hole, and two return springs respectively located on both sides of the reset plate are set on the mandrel. One end of the return spring is in contact with the reset plate, and the other end of the return spring is in contact with the spring fixing seat. superior. The linkage mechanism in the present invention can ensure that the two swing arms rotate synchronously to drive the safety tongs on both sides of the lower beam of the elevator to brake synchronously, preventing the elevator car from tilting during emergency braking; The spring can drive the swing arm to reset so that the safety gear releases the guide rail.

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...
