The mechanical condition of the elevator steel structure beam directly affects the operation safety of the elevator. Nowadays, some elevators without machine rooms are also widely applied to various occasions, and the installation of parts such as a machine room on the top layer of a hoistway, a main machine, a rope head and the like of the elevators is generally carried out by adopting a steel structure machine placing beam or a main rail, so that the stress of a steel structure in the hoistway is much larger than that of the elevator with the machine room. With the gradual popularization of elevator without machine room, the monitoring of the mechanical condition of the elevator steel structure beam is more and more important.
The most important mechanical condition of the elevator steel structure beam is the deformation. The conventional detection device for the deformation of the elevator steel structure beam is used for directly detecting the deformation amount, the deformation of the elevator steel structure beam is difficult to identify and detect accurately in real time only when the deformation amount is large enough, and in order to ensure that the elevator steel structure beam can safely load, the conventional detection device usually adopts a method of reserving enough strength allowance and performing preventive destructive tests and the like, but the methods are high in cost and long in period.
