| description | The utility model discloses a standard knot top increasing and reducing device for an elevator, and relates to the technical field of disassembly and assembly of special equipment. A seat plate rotating horizontally around a vertical pin shaft is arranged on each of four corners of the lower plane of a top beam sleeve frame, the upper parts of the seat plates support the top beam sleeve frame, and the lower part of each seat plate is provided with a seat port aligned with a main limb of a standard knot; after the seat plates rotate horizontally, the standard knot passes through a guide rail rack, so that the standard knot is increased or reduced from the top under the condition that the top beam sleeve frame is not assembled or disassembled, and the operating efficiency is improved; in normal work, hoisting weight is transferred to the seat plates through the top beam sleeve frame and then transferred to the main limbs of the standard knot by the seat plates, so that the whole structure is well stressed; when |
