Dragging steel belt

Abstract

The invention discloses a dragging steel belt which comprises a coating layer and multiple steel wire ropes arranged in the middle of the coating layer in a spaced manner. The multiple steel wire ropes are arranged on the same layer; each two adjacent steel wire ropes are opposite in twisting directions; each steel wire rope is of a two-layer twisting structure formed by a center strand and multiple outer-layer strands; each steel wire rope and the corresponding center strand are the same in twisting directions; the outer-layer strands and the corresponding center stand are opposite in twisting directions; the coating layer is adhered to the surfaces of the steel wire ropes; an elastic material of the coating layer is immersed into gaps of the steel wire ropes; and the coating layer is ofa flat structure. According to the dragging steel belt provided by the invention, the steel wire ropes have better flexibility and elasticity and are connected into a whole through the coating layer,so that the requirements on a breaking force and the ductility can be met, the fatigue life capacity of the product is greatly improved, a leveling effect of the steel belt is ensured, and the dragging steel belt is simple in structure and easy to realize standardization and mass production.

Description

technical field [0001] The invention relates to the technical field of elevator accessories, in particular to a traction steel belt. Background technique [0002] As a vertical transportation tool, traction elevator is closely related to modern social life. With the development of social economy and the acceleration of urbanization, there are more and more high-rise buildings. Elevators are responsible for the transportation of a large number of people and goods. Elevators The role played by buildings has become very important and an integral part of modern social life. [0003] In the elevator traction operation, the components that complete the functions of lifting, pulling, tensioning and carrying include traction steel belts or wire ropes. Steel wire ropes have the disadvantages of large amount of steel, easy wear, uneven force, lubrication, rust, troublesome maintenance, and high installation requirements. With the development of elevator technology, there has been a t...
