Description
Technical Field
The invention relates to an elevator technology, in particular to a car vibration damping device.
Background
At present, a steel wire rope is mostly adopted for dragging a lift car to realize vertical transportation, and because the steel wire rope is an elastic part, when the lift car is leveled, if people enter and exit, the lift car can cause oscillation in the vertical direction due to load change, so that the riding comfort is influenced; the aforementioned oscillation phenomenon is more pronounced especially when the hoisting height is large and the car is at a low floor.
Chinese patent document CN102530689A discloses a vibration suppression device for an elevator car, which suppresses vibration of the car in a vertical direction by generating a frictional force parallel to a car vibration direction by sandwiching a gate ball with a gate knife of a door system. The gate knife is a group of linkage clamping blades, and the blade gap is narrowed or widened by lifting or lowering a roller fixed on the single-side blade by a guide rail. When the blade gap is narrowed, the linkage clamping blade stably clamps the gate ball, and a friction force for inhibiting the vertical vibration of the car is generated. This kind of mode principle is simple, the realization of being convenient for, but its structure exists not enoughly: first, in order to secure a frictional force (a door ball holding force) for suppressing the vibration of the car, a guide rail having a length of at least one door stroke is provided, and the range of the width of the door to be opened is limited in consideration of the requirements of installation, rigidity, and the like of the guide rail. Secondly, if the linkage clamping device (door knife) is deformed or abraded, the linkage clamping device needs to be integrally replaced, the disassembly is inconvenient, and the maintenance cost is high.
