Abstract

The application relates to an elevator car floor structure, which includes an underframe and a bottom plate. The upper surface of the underframe corresponds to the bottom of the middle part of the bottom plate, and a rotating column is rotatably connected with it. There is a ring sleeve that can be set on the outside of the rotating column. The lower end of the inner peripheral surface of the ring sleeve is rotatably connected with a roller that can roll along the spiral groove; An adjustment disc is arranged horizontally on the side, and one end of the adjustment disc corresponding to each arc-shaped groove is fixedly connected with a fixed plate, and the arc-shaped groove is fixedly connected with a handle that can push the end of the arc-shaped groove away from the fixed plate to move away from the fixed plate under normal conditions. push spring. The application has the effect of realizing the cushioning of the car bottom in the car.

Description

technical field [0001] The present application relates to the field of elevators, in particular to an elevator car bottom structure. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. Modern elevators are mainly composed of traction machines (winches), guide rails, counterweight devices, safety devices (such as speed limiters, safety gears and buffers, etc.), signal control systems, cars and hall doors. These parts are respectively installed in the hoistway and machine room of the building. Steel wire rope friction transmission is usually used. The wire rope goes around the traction sheave, and the two ends are respectively connected to the car and the counterweight. The motor drives the traction sheave to lift the car up and down....
