Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] As shown in the figure, an elevator deceleration wing umbrella is equipped with a wing umbrella box 2 integrated with it on both sides of the elevator passenger box 1. The upper end of the wing umbrella box 2 has an umbrella hole 5, and the lower end is provided with an air inlet 4. Umbrella box 2 is equipped with deceleration wing umbrella 3 and umbrella bolt 6, under the situation of elevator normal lifting, wing umbrella 3 is contained in the wing umbrella box 2 and can not rush out to open, when elevator loses control for some reason, elevator passenger box 1 When the descending speed reaches or exceeds 9.8m / s2, the strong airflow will rush in from the air inlet 4 at the lower end of the wing umbrella box 2, thereby pushing the wing umbrella 3 out of the umbrella outlet hole 5 and opening it, and the umbrella bolt of the wing umbrel...

Abstract

The invention discloses an elevator deceleration wing umbrella. Wing umbrella boxes are arranged on two sides of an elevator passenger box; an umbrella outlet hole is formed on the upper end of the wing umbrella box, and an air inlet is formed on the lower end of the wing umbrella box; and the wing umbrella box is provided with a deceleration wing umbrella and an umbrella bolt. In the elevator deceleration wing umbrella, when the free fall acceleration of the elevator which is out of control due to a fault is equal to or more than 9.8m / s<2>, an elevator deceleration wing umbrella arranged on the external top part of the elevator opens automatically to reduce the falling speed of the fast falling elevator to a maximum degree and conducts a cushioning function when the elevator falls onto the ground, and thus, the injuries to the passengers are reduced.

Description

Technical field [0001] The invention relates to an elevator deceleration wing umbrella when the elevator falls for some reason. Background technique [0002] At present, there are safety hazards in the elevators used in high-rise buildings in use. Once the elevator loses control and falls freely, it will cause casualties to the elevator personnel. How to reduce and eliminate this safety hazard is an important issue today. problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides an elevator deceleration wing umbrella. When the elevator deceleration wing umbrella is out of control for some reason and the acceleration of free fall is equal to or greater than 9.8m / s2, the elevator deceleration wing umbrella arranged on the outer top of the elevator will Automatic opening, when the elevator descends rapidly, the falling speed can be reduced to the greatest extent, and when it touches the ground, the elevator can play a ro...
