Anti-falling protection device of elevator

Abstract

The invention discloses an anti-falling protection device of an elevator. The device comprises a vertical acceleration sensor, a controller, a storage battery, fixed rails, fixing rods and retractable motors, wherein the vertical acceleration sensor is disposed on the top of an elevator car, the fixed rails are arranged on the two sides of an elevator shaft, the fixing rods and the retractable motors are arranged on the side walls of the elevator car, and the fixed rails are evenly provided with multiple fixing holes. The controller is connected with the vertical acceleration sensor, the storage battery and the retractable motors, each retractable motor is connected with one end of the corresponding fixing rod, and the other end of each fixing rod corresponds to the corresponding fixing hole in the corresponding fixed rail in position. The two sides of the elevator shaft are provided with the fixed rails and the fixing rods, so that falling of the elevator can be prevented to some extent when the elevator is overweight and descends. Meanwhile, the vertical acceleration sensor is arranged so as to precisely detect the descending speed and the ascending speed of the elevator, operation of the elevator is better detected, operation safety of the elevator is increased, and the anti-falling protection device is worth popularization.

Description

technical field [0001] The invention discloses an elevator anti-fall protection device, which relates to the technical field of elevator safety. Background technique [0002] With the increase of high-rise buildings, the use of elevators is also increasing, and with the increase of elevator use, the frequency of elevator falling accidents is getting higher and higher. The quality of the existing elevator itself is not a problem. Whether the elevator can operate normally, A lot depends on the installation technique. Some elevator companies hire non-professional installers. They do not handle the elevator shaft and tracks carefully during the elevator installation process, which makes the balance of the elevator running poor, and even causes problems such as vibration and noise that are difficult to repair. These problems are It is solved by the installers. If the installation is not careful enough, the installed elevators will be very prone to problems. However, the existing...

Problems solved by technology

Some elevator companies employ non-professional installers. They do not handle the elevator shaft and tracks carefully during the elevator installation process, which makes the balance of the elevator during operation poor, and even causes problems such as vibration and noise that are difficult to repair. These problems are It is solved by the installer. If the installation is not careful enough, the installed elevator will be very prone to problems. However, the existing installation workers have different technical levels, and the installed elevator will have different performance.
