Preventive detection and maintenance method for elevator

Abstract

The invention provides a preventive maintenance method for an elevator. The preventive maintenance method for the elevator comprises the following steps of firstly, aiming at the load capacity detection of the elevator, installing a bottom plate with a pressure sensor on an inner bottom plate of the elevator, and enabling persons to slowly stand on the bottom plate; displaying the load capacity bythe pressure sensor every time when one person stands on the bottom plate, and until the elevator gives an alarm, recording pressure reading; and carrying an acceleration sensor onto the elevator, testing the acceleration between ascending and floor stopping as well as descending and floor stopping, and completing the acceleration detection. According to the preventive maintenance method for theelevator provided by the invention, load capacity detection, acceleration detection, levelness detection and steel wire rope detection of the elevator can be completed by using a simple method, so that the internal condition of the elevator can be known easily; if an abnormality occurs, the abnormality can be handled quickly, so that major faults in the elevator are avoided; and meanwhile, some common faults of an elevator door are effectively detected and processed through different methods, so that the comprehensive preventive detection is conducted on the elevator.

Description

technical field [0001] The invention relates to the technical field of elevator preventive detection, in particular to an elevator preventive detection and maintenance method. Background technique [0002] The elevator is a lifting structure that can drive goods and people to a certain height. The appearance of the elevator can save people the time to climb the stairs, save the time to reach the floor, and also make people save energy to reach the floor. floor, which greatly facilitates people's life. [0003] When the elevator is running, there will be various failures. In order to avoid the bad influence of the failure on people's life and work, it is necessary to regularly carry out preventive inspections on the elevator. [0004] However, the existing elevator detection methods are generally too simple. Generally, the elevator is detected by inspection. This method can only detect and troubleshoot the external faults of the elevator, and cannot quickly check and deal wi...
