Safety protection system for flat floor of elevator

Abstract

The invention discloses a safety protection system for a flat floor of an elevator. The safety protection system comprises a flat floor buffer, a trigger device and a stop device, wherein the flat floor buffer is fixed to the outer side of an elevator car; the flat floor buffer has two position states of an original position and a trigger position through rotating along a fixed shaft; the triggerdevice triggers the flat floor buffer and changes cover the flat floor buffer to the trigger position from the original position in the case that a running speed of the elevator car exceeds a set speed threshold value; and the stop device is fixed into an elevator shaft, and arranged at a position that the trigger state of the flat floor buffer can be interfered. In the case of safety accidents offalling, sliding and the like in the elevator, the trigger device triggers the flat floor buffer and changes cover the flat floor buffer to the trigger position from the original position in the casethat the running speed of the elevator car exceeds the set speed threshold value, the flat floor buffer makes contact with the stop device, and the speed of the elevator car is gradually lowered until the elevator car stops. Because the installation position of the stop device is a flat floor position, personnel taking the elevator can realize self-rescue by opening a door of the elevator car.

Description

technical field [0001] The invention belongs to the technical field of elevator safety operation equipment, in particular to an elevator leveling safety protection system. Background technique [0002] Modern people rely more and more on elevators, and people's travel safety hazards are also safety issues that need to be considered. For people living in high-rise buildings, the first and last means of transportation for daily travel is to take the elevator; because the elevator itself is used as a A kind of mechatronics equipment, it is unavoidable that there will be failures during its long-term operation and lifting process. [0003] In the existing elevator, if safety accidents such as falling and rolling occur, the safety of the elevator can only be guaranteed by the existing traction machine, safety gear and speed limiter. When the car falls or stalls downward, the traction machine brakes first, and if the traction machine brakes cannot stop the car, the speed limiter ...
