Speed reduction falling preventing elevator

Abstract

The invention discloses a speed reduction falling preventing elevator. The elevator comprises an elevator shaft and a car platform sill located in the elevator shaft and is characterized in that an embedded guide rail is arranged on the wall of the elevator shaft, the car platform sill is installed on the embedded guide rail in a matched mode through a guide shoe, and a flexible side wing matched with the cross section of the elevator shaft in shape and a rolling mechanism are installed at the bottom of the car platform sill. When the car platform sill operates normally, the rolling mechanism controls the flexible side wing to roll so that the car platform sill can operate normally, and when the car platform sill falls, the rolling mechanism controls the flexible side wing to be unfolded to form motive seal with the wall of the elevator shaft so that the car platform sill can slow down under the action of bottom air pressure. The speed reduction falling preventing elevator has the advantages that when the car platform sill falls, the flexible side wing is unfolded to form motive seal with the wall of the elevator shaft, so that the car platform sill becomes a structure similar to a piston to extrude air below, and high pressure is generated to offset gravity of the car platform sill to reduce speed.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a deceleration and anti-falling elevator. Background technique [0002] The emergence of high-rise buildings has greatly improved the land utilization rate and brought better sightseeing opportunities for people. At the same time, it has enhanced the charm of the city's image and become a display window for urban development. As one of the essential components in high-rise buildings, elevators play an important role. According to incomplete statistics, as of 2015, there are more than one million elevators in service across the country. It can be seen that elevators have become one of the indispensable tools in daily life. The number of elevators is not only increasing day by day, but people's research on elevators is also deepening day by day. In the long-term research and use, people have found that the safety of elevators has become the most important concern, a...
