Difficulty in moving them can reduce work efficiency and affect the progress of inspection and maintenance. Unstable escalators can easily damage the engineering structure being inspected. Therefore, in order to address the above shortcomings, a dedicated escalator for engineering inspection is proposed. Utility Model Content

[0033] Working Principle: After starting motor 3, it drives the rotating rod 4 to rotate a certain distance, which in turn drives the elliptical plate 5 to rotate. This causes the elliptical plate 5 to move the sliding block 9 up and down, which in turn moves the support plate 10 up and down. After the support plate 10 compresses the return spring 8, motor 3 drives the rotating rod 4 to rotate again. Under the force of the return spring 8, the escalator is supported and moved, thus reducing the risk of falls or tilting, ensuring the safety of workers, and allowing them to quickly reach different work areas, reducing wasted time. Starting motor 12 enables motor 12 to... 2. This drives the rotating shaft 13 to rotate, which in turn drives the drive sprocket 14 to rotate. The drive sprocket 14 then drives the chain 15 to move, which in turn drives the driven sprocket 17 to rotate. The driven sprocket 17 then drives the rotating shaft 16 to rotate, which in turn drives the fixed rod 18 to rotate. The rotating shaft 16 then drives the fixed rod 18 to rotate, which in turn drives the connecting rod 19 to rotate. This allows the connecting rod 19 to slide the support platform 20 up and down, thus enabling the escalator to be folded and raised / lowered. This allows the folded escalator to occupy less space and be easily stored when not in use.
