Elevator steel wire rope end combination device capable of automatically adjusting angle

Abstract

The invention relates to an elevator steel wire rope end combination device capable of automatically adjusting the angle. The elevator steel wire rope end combination device mainly comprises a taper sleeve, a rope hitch plate, a protruding block, a base gasket, spring gaskets, a pull rod and a spring, wherein an inward concave cambered surface is arranged at a hole of the rope hitch plate, an outward convex cambered surface is arranged on one surface of the protruding block, and the inward concave cambered surface of the rope hitch plate can be completely attached to the outward convex cambered surface of the protruding block; the protruding block can slide left and right around the inward concave cambered surface of the rope hitch plate; the pull rod penetrates through a through hole of the rope hitch plate and a through hole of the protruding block; the lower end of the pull rod is connected with one end of the taper sleeve; the engineering plastic base gasket, one metal spring gasket, the spring, the other metal spring gasket and a nut are sequentially installed at the upper end of the pull rod from bottom to top; and a cotter pin is installed on the uppermost portion of the pull rod. The steel wire rope end combination device can completely eliminate horizontal force generated when a steel wire rope is not perpendicular to the horizontal plane in the vertical running process of an elevator, the steel wire rope end is only pulled, the horizontal force of a rope end device is eliminated, external action damage of the steel wire rope is reduced, the reliability of a rope end suspension device is guaranteed, and the service life of the steel wire rope is prolonged.

Description

technical field [0001] The invention relates to an elevator steel wire rope end combination device for automatically adjusting the angle, and at the same time relates to the manufacture of elevator steel wire rope end parts. Background technique [0002] The wire rope end structure of the elevator is an important part of the elevator suspension device. The standard stipulates that the combined joint of the steel wire rope and its end joint should be able to bear at least 80% of the minimum breaking load of the wire rope. The connection structure of the rope end directly affects the safety and reliability of the elevator. When the elevator runs up and down, the angle between the steel wire rope and the horizontal plane is constantly changing, and the angle of the steel wire rope near the rope end changes the most. For example, the rope end combination device is directly fixed on the load-bearing plate. The horizontal force generated not perpendicular to the horizontal plane ...
