Plate-type eddy current elevator buffer

The invention relates to the technical field of elevators, and discloses a plate-type eddy current elevator buffer, which comprises a mounting base fixed at the bottom of an elevator shaft, an outer pipe fixed on the mounting base, and a piston rod movably inserted in the outer pipe up and down, a non-magnetic magnetic sleeve is fixedly arranged at the lower end of the piston rod, a fixed magnetic cylinder is fixedly arranged in the outer pipe, U-shaped magnetic poles are annularly arranged in the fixed magnetic cylinder, and the protruding side edges of the non-magnetic magnetic sleeve are matched with the interiors of the U-shaped magnetic poles in a one-to-one mode. Therefore, the non-magnetic conductive sleeve slides up and down in the groove in the middle of the U-shaped magnetic pole under the condition that the non-magnetic conductive sleeve is not in contact with the U-shaped magnetic pole. The damping device is suitable for elevators at any speed, the damping force is increased along with increase of
