A building elevator shaft wall straightness inspection device

Abstract

A device for inspecting the straightness of a building elevator shaft wall comprises a buoyancy lifting device and a wall-climbing detection device. At least two wall-climbing detection devices are supported on the surface of the elevator shaft wall and connected to the buoyancy lifting device, allowing for adjustment of their longitudinal height within the elevator shaft. Each wall-climbing detection device is equipped with a transmission-connected crawling mechanism and a pressure detection mechanism. The crawling mechanism can abut against the shaft wall and roll back and forth relative to it, while the pressure detection mechanism drives the crawling mechanism and senses the lateral pressure generated by uneven shaft walls. This invention can save manpower during the entire shaft wall straightness inspection process, improve the efficiency of shaft wall straightness inspection, and meet the construction requirements of simultaneously inspecting the straightness of multiple layers of shaft walls.
