The invention relates to a novel elevator safety guarantee system, and belongs to the technical field of elevators. The novel elevator safety guarantee system is connected with a control system and comprises a buffering mechanism, a speed reduction mechanism and an automatic speed detection mechanism. The buffering mechanism is arranged on an elevator car and the bottom of an elevator shaft and used for buffering the elevator car. The speed reduction mechanism is mounted on the elevator car and connected with the control system; and when the system detects abnormal falling of the elevator car,the speed reduction mechanism automatically slows down the elevator car and fixes the elevator car in the elevator shaft. The automatic speed detection mechanism detects the operating speed of the elevator car in real time and feeds the operating speed to the control system. According to the novel elevator safety guarantee system, through the cooperation of the buffering mechanism, the speed reduction mechanism and the automatic speed detection mechanism, the safety of an elevator in the operating process is greatly improved; and meanwhile, the size and weight of the elevator are not excessively increased by the safety guarantee system, and manufacturing and installation are very convenient.
Description
technical field [0001] The invention relates to a novel elevator safety guarantee system, which belongs to the technical field of elevators. Background technique [0002] During the use of the elevator, the accident of the elevator box falling due to the failure of the hoisting device of the elevator occurs occasionally, so once the elevator box falls, the casualties of personnel are just more serious. [0003] Elevators in the prior art are composed of elevator passages, cars, hoisting devices and buffer mechanisms. The setting of the buffer mechanisms takes up a large part of the volume of the car, and the deceleration of the car is unreliable during the use of these buffer mechanisms. [0004] The stroke length of the energy consumption of the existing hydraulic buffer is not enough, so that it cannot effectively absorb and digest the impact force generated when the car falls, and the safety factor of the people in the car is low. Therefore, a novel solution needs to be ...
