Elevator emergency self-rescue system and vertical type elevator

Abstract

The invention discloses an elevator emergency self-rescue system and a vertical type elevator. The vertical type elevator is provided with a portal crane and a holding brake. The elevator emergency self-rescue system comprises a standby power supply, an emergency operator, an elevator state detection device, a levelling signal detection device, a portal crane power supply switching device and a holding brake power supply control device. The emergency operator can be operated by people in a lift car; when passengers get trapped in the lift car due to the failure of the elevator, the elevator can automatically run to a leveling position through operating the emergency operator, and an elevator door is opened, so that the self-rescue is realized, the passengers can get out of the elevator forthe first time without the need for contacting other people, the safety performance of the elevator is improved, and the secondary accident rate is reduced; and in addition, the holding brake power supply control device and the portal crane power supply switching device act according to the outputs of the elevator state detection device, the levelling signal detection device and the emergency operator, so that the elevator emergency self-rescue system provided by the invention cannot influence the running of an existing system of the elevator.

Description

technical field [0001] The invention relates to the technical field of elevator escape, in particular to an elevator emergency self-rescue system and an upright elevator in which trapped persons can escape by themselves. Background technique [0002] Elevators bring comfort and convenience to people's lives, reflecting the continuous improvement of people's living standards. Elevators have become an indispensable part in high-rise apartments, buildings, airports, stations, etc., and are closely related to people's lives and travel. However While elevators bring convenience to people's lives, they also bring many hidden dangers to people. [0003] When the elevator is in operation due to a sudden power failure or the failure of the elevator itself, the elevator pod will stop suddenly, resulting in the accident of elevator trapping. Elevator trapping is the most common type of elevator accident. If it cannot be solved quickly, the state of the trapped personnel in the elevato...

Problems solved by technology

[0005] The above two methods, the first one, if the elevator itself is faulty, the rescue cannot be realized automatically; the second one must wait for external personnel to rescue, and the trapped people cannot be rescued in time
