Description
Technical Field
[0001] The utility model belongs to the technical field of elevator detection, and particularly relates to an elevator track detection system. Background Art
[0002] With the rapid development of the economy, car elevators have become standard equipment in many high-rise buildings, and elevator guide rails, as an important part of the car elevator transportation system, are directly related to the stability and safety of the car elevator operation. The elevator guide rails play a guiding role when the car elevator is running. During the design, installation and verification of the elevator guide rails, the coplanarity and verticality of the elevator guide rails need to be tested. The gauge deviation and verticality deviation of the elevator guide rails are important data indicators for measuring the quality of elevator installation, affecting the safe operation of the elevator.
[0003] At present, the detection methods of existing guide rail detection equipment are mainly divided into laser measurement method, inclination sensor method and machine vision method. Among them, the machine vision method uses laser network projection technology to identify the characteristics of the guide rail. This method is mainly suitable for the use of elevator guide rail manufacturing process, and the effect is not good in on-site detection. The inclination sensor method and laser measurement method can measure the parameters of elevator guide rails on-site, and have the characteristics of accurate measurement results and fast measurement speed. However, when these two measurement methods are applied on-site, the guide rails will vibrate when the elevator car is running, due to the wear of the guide shoes, the large gap between the guide shoes and the guide rails, and the uneven tension of the wire rope, which will cause the elevator to shake, and the detection equipment installed on the guide rails will vibrate, which will have a great impact on the measurement accuracy. Therefore, the guide rail detection equipment of these two methods can usually only be used for guide rail detection when the elevator is stopped, and cannot reflect the dynamic situation of the guide rails when the elevator is running.
