Elevator protection net

Abstract

The invention discloses an elevator protection net which comprises lifting ropes fixedly arranged in an elevator shaft. The two ends of each lifting rope are connected with a top floor and a bottom floor at the two ends of the elevator shaft correspondingly. Protection net bodies are arranged on the lifting ropes at intervals. Due to the fact that the lifting ropes independent of an elevator car are arranged in the elevator shaft, borne weight is set on the floors, and the bearing amount of the elevator car is not affected. In addition, each protection net body further comprises a left-side protection net body and a right-side protection net body, wherein net collecting mechanisms are arranged above and below the left-side protection net body correspondingly, net collection mechanisms are arranged above and below the right-side protection net body correspondingly, and the net collection mechanisms are arranged on the elevator car. When an elevator runs to corresponding elevator hall openings, the left-side protection net bodies and the right-side protection net bodies can be contained leftwards and rightwards correspondingly to open the elevator hall openings. In addition, when the elevator hall openings fail, the protection net bodies expanded at the corresponding elevator hall openings can prevent people from entering the shaft, people can be prevented from falling into the shaft, and personnel safety is ensured.

Description

technical field [0001] The invention relates to an elevator protective net. Background technique [0002] An elevator is a vertical lift powered by a motor, equipped with a car, and used in multi-storey buildings to take people or carry goods. As a means of transportation in high-rise buildings, elevators bring great convenience to people's lives, but at the same time, taking elevators also contains great risks, and accidents occur that threaten people's lives. There are many factors that make the elevator unsafe, but the most harmful one is the falling accident of the shaft, which directly causes casualties. Most of the reasons are the failure of the elevator door mechanism, or artificial illegal operation, which causes the car to not be on the floor. However, when the elevator door is accidentally opened, passengers or staff fall into the hoistway, causing personal injury accidents. At present, most elevators use mechanical anti-fall protection devices, but the safety fac...

Problems solved by technology

There are many factors that make the elevator unsafe, but the most harmful one is the falling accident of the shaft, which directly causes casualties. Most of the reasons are the failure of the elevator door mechanism, or artificial illegal operation, which causes the car to not be on the floor. However, when the elevator door is accidentally opened, passengers or staff fall into the well, causing personal injury accidents. At present, most elevators use mechanical anti-fall protection devices, but the safety factor of mechanical protection devices is low and requires frequent manual maintenance. Use brings trouble and wastes resources
