A car frame is arranged outside the elevator car, the steel wire rope is arranged at the top of the car frame, the tractor is arrangedat the upper end of an elevator shaft, the steel wire rope is wound on a rotating wheel of the tractor, one end of the steel wire rope is connected with the counter weight, the guide shoes are arranged on two sides of the elevator car, the guide rails are fixed onto elevator shaft walls on two sides of the elevator car, the broken rope fastening device is arranged between the top of the elevatorcar and the steel wire rope, the powder spraying device is arranged at the bottom of the elevator car, the safety airbag device is arranged at the bottom of the elevator car, a buffer air cushion is arranged at the bottom of the elevator car, and the buffer device is arranged at the bottom of the elevator shaft. Safety of the elevator is improved, and life safety of passengers is improved.

Description

technical field [0001] The invention belongs to the technical field of elevator safety, in particular to a passenger elevator with high safety performance. Background technique [0002] With the continuous increase of high-rise buildings, elevators have become an indispensable tool in people's lives. Elevators are convenient, fast, and energy-saving. Although the elevator technology is relatively mature and its performance is relatively perfect, potential safety hazards still exist, and various elevator accidents emerge in an endless stream, causing great injuries and economic losses. In elevator accidents, especially the sudden fall of the elevator, the damage to personnel is the greatest. The bottom of the existing elevator car is equipped with a buffer device, and the elevator shaft is also installed with a hard limit between each floor, which can provide protection when the elevator car falls. Certain buffering effect, but the buffering effect of the above-mentioned dev...

Problems solved by technology

Although the elevator technology is relatively mature and its performance is relatively perfect, hidden safety hazards still exist, and various elevator accidents emerge in endlessly, causing great injuries and economic losses.

In elevator accidents, especially the sudden fall of the elevator, the damage to personnel is the greatest. The bottom of the existing elevator car is equipped with a buffer device, and the elevator shaft is also installed with a hard limit between each floor, which can provide protection when the elevator car falls. A certain buffering effect, but the buffering effect of the above-mentioned devices is limited, and in many cases the acceleration of the elevator car falling cannot be reduced to a safe level, and residents still have certain risks when taking the elevator

When the existing elevator falls, the life safety of personnel cannot be guaranteed, which seriously threatens people's right to life
