Embodiment 1

[0018] An elevator equipped with a safety protection device is provided, comprising an elevator car 1, an elevator shaft 5 and a fall sensing device, the wall 2 of the elevator shaft 5 is provided with a hole belt 3, and the hole belt 3 is formed by the wall 2 A plurality of holes 7 are arranged in a straight line. The bottom of the hole 7 is fixed with a spring 9, the spring 9 is connected to the steel bar 8, and a switchable closing device 10 is arranged outside the hole 7. When the closing device 10 is closed When the closing device 10 blocks the hole 7, the steel bar 8 is blocked in the hole 7. When the closing device 10 is opened, the closing device 10 is removed from the hole 7, so that the steel bar 8 is stretched by the action of the spring 9. It can be seen that the opening of the closing device 10 is controlled by the drop sensing device, and when the drop sensing device senses that the elevator car 1 falls, the closing device 10 is opened; the bottom of the elevator ...

Abstract

The invention discloses an elevator equipped with a safety protection device, which includes an elevator car, an elevator shaft and a fall sensing device. The wall of the elevator shaft is provided with a hole belt, and the hole belt is composed of a plurality of holes on the wall. The holes are arranged in a straight line, the bottom of the hole is fixed with a spring, the spring is connected to the steel bar, and a switchable closing device is arranged outside the hole. When the closing device is closed, the closing device blocks the hole to seal the steel bar. Blocked in the hole, when the closing device is opened, the closing device is removed from the hole, so that the steel bar protrudes through the action of the spring, the opening of the closing device is controlled by the drop sensing device, when the drop sensing device When the fall of the elevator car is sensed, the closing device opens. When the elevator car falls, the speed sensor will open the closing device, the steel bar will stretch out through the spring, and the steel bar will be cut off by the cutter, thereby reducing the falling speed.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator equipped with a safety protection device. Background technique [0002] With the improvement of people's living standards and the acceleration of the pace of life, modern people pay more and more attention to the quality of life. For this reason, high-rise buildings are without exception equipped with one or more elevators. Elevators have been widely used in modern social life for a long time. [0003] Elevators are essential as a means of vertical transportation. The safety of elevators has attracted more and more attention, and accidents that have occurred have threatened people's lives. There are many factors that constitute unsafe elevators, but the most harmful one is the falling accident of the shaft, which directly causes casualties. [0004] How to prevent the elevator that can be controlled in time to fall when the elevator falls, is one of problems to be solved ...
