WIPO Patent Application WO/2019/090864

A1

A hydraulic telescopic rod structure of a floor plate, pertaining to the technical field of escalators. The structure has a floor plate (1). A truss (3) used for fixing the floor plate is disposed below the floor plate. Mounting supports (4) are disposed on the truss. A rotating shaft (5) is disposed on each mounting support. A hydraulic telescopic rod (6) is connected to the mounting support. A fixing support (8) connected to the hydraulic telescopic rod is provided on the floor plate. Fixing bolts (31) are detachably connected to the floor plate. A fixing plate (2) is fixedly connected to the truss via a hinge connection at one side of the floor plate. A limit switch (10) is disposed between the fixing bolts. The hydraulic telescopic rod has a hydraulic cylinder (11) connected to a control system (12). The hydraulic telescopic rod will slowly push the floor plate upwards automatically after screws on the floor plate are removed, such that a worker can directly enter a machine room to perform maintenance without needing to move a heavy floor plate. The limit switch prevents the telescopic rod from being activated when the floor plate is closed.
