Problems solved by technology

However, in practice, there are accidental falling incidents of high-altitude elevator cars, which shows that the above two safety protection systems still have loopholes and cannot completely prevent high-altitude free falls. Free fall motion, will bring fatal injury to passengers

Embodiment Construction

[0011] First of all, the automatic measuring instrument device (10) continuously transmits the relevant data information of measuring the running speed of the car and the height of the car from the bottom of the elevator shaft to the central integrated control device (15) when the elevator is running, and the central integrated control device (15) receives the signal Afterwards, judge whether other devices need to be started according to the situation. If it needs to be started, the central integrated control device will send a signal to the car top umbrella-shaped deceleration device (5), and the car top umbrella-shaped deceleration device (5) will start. The height and speed information transmitted by the central integrated control device activates the corresponding level of deceleration device. Here it means that if the car descends at a low speed, the first-level deceleration device is activated to pop up a small umbrella-shaped deceleration parachute. If the speed is high,...

Abstract

The invention discloses a vertical elevator fall saving device adopting umbrella shape, speed reducing baffle and spring buffer technology. The saving device consists of an automatic measurement instrument device, a cage bottom plate buffer device, a cage roof buffer device, a cage top umbrella-shaped speed reducing device, a voice and human-machine interaction device, a shaft well speed reducing baffle plate device, a shaft bottom spring buffer device and a central integrated control device. The saving device can effectively overcome the defects of the conventional elevator safety protection system; and the cage can be decelerated under the combined action of the automatic measurement instrument device, the cage top umbrella-shaped speed reducing device, the shaft well speed reducing baffle plate device and the like, and soft landing is finally realized so as to fulfill the purpose of protecting passengers' lives. The saving device is particularly suitable for vertical elevator cage fall of medium and low-layer buildings, and furthest protect the passengers' lives.

Description

technical field [0001] The invention relates to an umbrella-shaped, decelerating baffle, and spring buffer technology, in particular to a device for rescuing passengers when a car in a vertical elevator shaft falls unexpectedly from a high altitude, and belongs to the technical field of mechanical equipment safety design. Background technique [0002] At present, known elevator safety protection systems are generally composed of two major parts, a mechanical safety protection device and an electrical safety protection device. Mechanical safety protection devices are mainly speed limiters and safety gears, buffers, brakes, landing door locks and car door electrical interlocking devices, door safety protection devices, car top safety windows, car top protective railings, toe guards, etc.; Safety protection includes direct electric shock protection, indirect electric shock protection, electrical fault protection, electrical safety devices, etc. However, in practice, there are ...
