Embodiment Construction
[0032] 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.
[0033] Such as Figure 1 to Figure 16 In the shown embodiment of the elevator car braking device of the present invention, the elevator car braking device includes an elevator lower beam 10, and safety gears 20 that cooperate with the elevator guide rails are respectively installed on both sides of the elevator lower beam 10. The lower beam 10 is also equipped with a linkage mechanism for driving the safety gear 20 to move synchronously. The linkage mechanism includes a fixed plate 31, a linkage shaft 32 and a rocker arm 33. On the side, the fixed plate 31 is provided with a mounting hole 311 for installing the linkage shaft 32. The two ends of the linkage shaft 32 protrude from the fixed plate 31 and...

The invention relates to an elevator lift car braking device. The elevator lift car braking device includes an elevator lower beam. The two sides of the elevator lower beam are provided with safety clamps and a linkage mechanism respectively. The linkage mechanism comprises a fixed plate, a linkage shaft and a rocker arm. The two ends of the linkage shaft are fixedly connected with the rocker armrespectively, and the middle of the rocker arm is fixedly connected with the linkage shaft and rotates along with the linkage shaft. One end of the rocker arm is connected with the safety clamps, andthe other end of the rocker arm is provided with a lifting gear shaft used for being connected with a steel wire rope of a speed limiter. The position, close to the fixed plate, of the linkage shaft is sleeved with a torsional spring. A torsional spring positioning plate is also installed on the fixed plate. The torsional spring positioning plate is provided with two clamping slots used for fixingthe torsional spring. Two clamping arms of the torsional spring limit the lifting gear shaft between the two clamping arms. According to the elevator lift car braking device, when an elevator lift car needs emergent braking, two swing arms on the both sides of the elevator lower beam are connected through the linkage shaft, the two swing arms can rotate synchronously to drive the safety clamps onthe both sides of the elevator lower beam to brake synchronously, and in this way, the elevator lift car can be prevented from tilting during emergent braking.
Description
technical field [0001] The invention relates to elevator safety control technology, in particular to an elevator car 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 the s...
