Technical Field

The invention relates to the technical field of safety measures of elevators, in particular to an emergency danger avoiding device for elevator out of control.

Background

An elevator is a vertical elevator powered by an electric motor and equipped with a box-like car for carrying people or cargo in a multi-story building. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. A vertical lift elevator has a car that travels between at least two vertical rows of rigid guide rails. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. According to the speed, the elevator can be divided into a low-speed elevator (less than 1 m/s), a high-speed elevator (1-2 m/s) and a high-speed elevator (more than 2 m/s). The hydraulic elevator begins to appear in the middle of the 19 th century and is still applied to low-rise buildings until now. In 1852, e.g. austs in the united states developed a safety hoist for wire rope hoisting. In the 80 s, further improvements were made to the drive means, such as motors driving the winding drum via a worm drive, the use of counterweights, etc. At the end of the 19 th century, friction wheel transmission is adopted, and the lifting height of the elevator is greatly increased.

The conventional emergency danger avoiding device of the elevator can only buffer the lift car, and can be forcibly stopped in a material resource mode at the same time, so that safety measures cannot be implemented on passengers in the lift car.

Disclosure of Invention

The invention aims to solve the following problems of the device: the emergency danger avoiding device of the elevator can only buffer the lift car, and meanwhile or forcibly stops in a material resource mode, so that safety measures cannot be implemented on passengers in the lift car.

The passenger protection coffin comprises a protection coffin body, an outer coffin sealing door, a damping cotton core layer, a gas expansion cavity, a damping spring and a stabilizing plate, wherein the outer coffin sealing door, the damping cotton core layer and the gas expansion cavity are arranged on the protection coffin body, and the damping spring and the stabilizing plate are arranged below the protection coffin body.

Coffin sealing door is installed respectively through articulated mode in protection coffin body both sides, is provided with self-lock device on the coffin sealing door, and the shock attenuation cotton sandwich layer is the inner liner of the protection coffin body, and the shock attenuation cotton sandwich layer is the same with vehicle airbag's material, and the inside of shock attenuation cotton sandwich layer is provided with the gas expansion chamber, and the gas expansion intracavity portion has gas, and damping spring's upper end links to each other with protection coffin body below surface, and damping spring's lower extreme links to each other with steadying plate top surface, and the below surface of steadying plate is provided with one deck non-slip rubber layer.

Compared with the prior art, the invention has the advantages that:

(1) when this scheme was used, when this elevator appeared out of control and dropped down by a wide margin, opened the resistance and supported the ware, the resistance props the ware and carries out the mode through the parachute and reduce the whereabouts of this elevator, and its beneficial effect is: the falling speed of the elevator is increased by opening the resistance falling cover on the resistance supporting device, and the impact force of the elevator is greatly buffered.

(2) The design of the passenger protection coffin is used for ensuring the safety measures of passengers, and has the advantages that: the passenger enters into the inside of the passenger protection coffin, and the lining inside the passenger protection coffin can completely wrap the passenger in an air bag mode, so that the injury of the passenger is reduced.

(3) The damping spring and the stabilizing plate are designed to damp when contacting with the car, and have the beneficial effects that: the shock absorption springs and the stabilizing plates further reduce the impact force between the protective coffin and the rider, and the safety performance of the rider is ensured.
