Abstract

The invention discloses a deformation tester for an elevator landing door, which comprises a supporting horizontal bar, two front chutes are arranged at intervals above and below the front surface of the supporting horizontal bar; two rear chutes are arranged at intervals above and below the rear surface of the supporting horizontal bar; The rear chute is slidingly connected with a rear positioning sliding connection mechanism; the rear positioning sliding connection mechanism is fixedly connected with a load plate upward, the load plate is connected with an electric push rod, the electric push rod is connected with a displacement sensor, and the extension rod of the electric push rod is connected with a connecting rod. Column, the connecting column is connected with a load cell; two front chutes are slidably connected to the left side of the bearing plate with a left front positioning sliding connection mechanism; two front chutes are slidably connected to the right side of the bearing plate with a right front positioning sliding connection mechanism. The invention can test the surface deformation of any position of the elevator landing door without using multiple tools, and the detection process can be operated by a single person, which not only improves the detection efficiency, but also improves the accuracy of the detection, and can adapt to various widths elevator landing doors.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a testing device for elevator landing doors. Background technique [0002] With the rapid increase in the number of elevators and the gradual increase in the service life of elevators, elevator safety issues have become increasingly prominent. The safety of elevator use is related to our daily life. The landing door and car door of the elevator are the most direct protective barrier for the users. [0003] The landing door car door is mainly to isolate each floor from the elevator shaft, protect the user from contact with the inner parts of the shaft, and prevent the occurrence of elevator shearing, impact, personnel falling and other casualties. During the use of the elevator, the landing door car door is a mechanism with high frequency of use. Due to reasons such as maintenance, users, management, and quality, accidents caused by elevator landing door car door problems occur...
