Problems solved by technology

[0004] The object of the present invention is to provide a method that can slow down the speed of the elevator car to a stop when the elevator car rises too fast, can buffer the elevator car when the elevator car rises to a high-level out of control, and can protect the elevator car. The emergency buffer device that can prevent the elevator car from rushing to the top and the elevator that selects the device can solve the problem that the contact point of the elevator brake in the above-mentioned background technology will be caused by excessive use time or long service life. The friction between the block and the brake wheel will cause wear or corrosion, and the braking effect of the brake will decrease or fail.

Abstract

The invention discloses an emergency buffer device capable of preventing a lift car from rushing to the top and an elevator using the emergency buffer device. The emergency buffer device comprises an elevator derrick, a mounting seat, a servo motor, a power shaft and the like. The mounting seat is fixedly mounted on the right side of the top face of the elevator derrick, the servo motor is fixedly mounted on the mounting seat, and the power shaft is welded to the left end of an output shaft of the servo motor. Speed reduction calipers make contact with the power shaft, the speed reduction calipers exert resistance on the power shaft, so that the rotating speed of the power shaft and the rotating speed of devices on the power shaft are gradually decreased, meanwhile, through the effect of a first compression spring, a shifting clamping rod limits a movable limiting wheel, the rotating speed of the movable limiting wheel is decreased, the lifting speed of the lift car is decreased, then the lift car can stop in the gradual deceleration process, and the phenomenon that the lift car ascends too fast and rushes to the top when the braking effect of a brake is insufficient is prevented.

Description

technical field [0001] The invention relates to the field of elevator safety, in particular to an emergency buffer device capable of preventing a car from rushing to the roof and an elevator using the device. Background technique [0002] Along with the continuous growth of elevator utilization rate, followed by the high number of elevator accidents, the safety of elevators has become a new hidden danger for urban public safety. In moving occasions, the elevator brake is an important safety device for the elevator. The safety and reliability of the elevator brake is one of the important factors to ensure the safe operation of the elevator. Next, it forms a friction brake for power-off braking, thus ensuring the safety of the elevator. [0003] With the long-term use of the elevator, the contact point of the elevator brake will have problems due to long-term use or long-term use, resulting in poor contact or adhesion of the elevator brake contact point, and the contact effec...
