AI Technical Summary
Existing equipment for detecting the deformation of elevator foot guards is bulky and costly, making it difficult for elevator inspection and testing organizations to meet their testing needs quickly and conveniently.
Design a simple testing device including a Z-shaped horizontal base, a push-pull force gauge, a rotating push rod assembly, and a distance measuring assembly. By combining and setting the device, it can be placed parallel and stably on the floor of the station. The deformation value can be obtained by directly reading the value. The distance measuring assembly with mechanical reading and the commonly used push-pull force gauge are used to reduce the configuration cost.
It enables rapid and accurate measurement of the deformation of the foot guard, reduces testing costs, improves testing efficiency, and is suitable for the needs of large-scale elevator inspection.
