AI Technical Summary

Technical Problem

The prior art is difficult to accurately detect the elastic deformation and permanent deformation of elevator doors, and the operation is cumbersome.

Method used

A pressure-bearing strength detector for elevator doors is designed, which uses the changes in the two phase state of the current-changing liquid to convert the deformation of the elevator door into the liquid level change of the detection liquid in the detection tube, and detects the elasticity and permanent deformation of the elevator doors by detecting the changes in the liquid level in the tube.

Benefits of technology

Accurate detection of elastic deformation and permanent deformation of elevator doors is achieved, the operation process is simplified, and the problem of inaccurate contact between the inspection pressure head and the elevator door is avoided.

Abstract

The present invention belongs to the technical field of elevator door detection, and specifically discloses an elevator door pressure strength tester, including a placement rack, the placement rack is arranged in a U shape, the side wall of the placement rack is provided with a lifting and adjusting component, the lifting and adjusting component is provided with a detection trigger component, the lifting and adjusting component and the detection trigger component are provided with a detection propulsion component, the side wall of the lifting and adjusting component is provided with a bending guide component, and the bending guide component is provided with an automatic straightening component. The present invention does not need to adjust the detection pressure head to be in contact with the elevator door, and through the change of the two-phase state of the electrorheological fluid, the deformation of the elevator door is converted into the liquid level change of the detection liquid in the detection tube, so that the elastic deformation and permanent deformation of the elevator door can be conveniently detected.
