Problems solved by technology

Extrusion deformation is the process in which the wires at the far sheave point of the same cross-section gradually extrude toward the near sheave point through adjacent wires, resulting in the deformation of the traction rope. At this time, the mutual displacement between the wires inside the traction rope will produce The friction force wears the rope, which leads to the breakage of the rope. The larger the cross-sectional diameter of the traction rope, the greater the extrusion deformation, the greater the abrasion of the rope inside the traction rope, the more serious the breakage of the rope, and the shorter the service life of the traction rope

Abstract

The invention relates to a traction rope for a dumbbell-shaped elevator. The traction rope comprises at least two traction bodies and is characterized in that the two adjacent traction bodies are connected through a connector, and the outer surface of the connector is in smooth transition with the outer surfaces of the traction bodies. The traction rope has the advantages that the contact area between the traction rope and a traction groove is greatly increased, and the friction is increased, so that the work efficiency is improved and the service life of the traction rope and the traction groove is prolonged.

Description

technical field [0001] The invention relates to a traction rope, in particular to a traction rope for an elevator. Background technique [0002] Elevators have penetrated into many corners of people's lives. Elevator traction ropes are an important part of the elevator system. The quality and performance of elevator traction ropes directly affect the safety factor of elevators. The existing elevator traction ropes are single-strand ropes, even multi-strand ropes They are also independent of each other. [0003] When the single-strand traction rope used in the elevator enters the traction groove of the traction wheel, the rope will roll in the traction groove due to the friction of the groove edge, and the resulting shear force will cause the rope to be sheared and damaged , wire breakage occurs, and the life of the traction rope is affected. [0004] At the same time, the relative friction between the traction rope and the traction groove makes the traction rope and the tr...
