Elevator compensating rope

Abstract

The invention discloses an elevator compensating rope. The elevator compensating rope comprises stress elements, an outer plastic layer and an outsourcing layer, the multiple stress elements are arranged in the outer plastic layer, the outsourcing layer is arranged outside the outer plastic layer, the outer plastic layer is of a flat structure, the two sides of the outer plastic layer are convex semicircles, and grooves are formed in the middle positions of the two sides of the outer plastic layer respectively; the outer plastic layer is formed by filler and plastic in an extrusion mode, and the filler is prepared from, by weight, 40-60 parts of low-density calcium powder, 20-25 parts of blanc fixe, 23-33 parts of silica powder, 10-15 parts of greywacke powder, 11-16 parts of idocrase powder, 20-34 parts of stearic acid, 20-30 parts of plasticizer, 2-5 parts of drying agent, 4-6 parts of anti-aging agent, 3-5 parts of antifreezing agent, 5-10 parts of lubricating agent and 29-59 parts of polyvinyl chloride. The elevator compensating rope has the advantages of being simple in structure, reasonable in design, low in density, high in strength and elasticity and capable of prolonging the service life and reducing the ageing speed of the outer plastic layer.

Description

technical field [0001] The invention relates to an elevator compensation and balance system, in particular to an elevator balance cable. Background technique [0002] At present, most elevator balance cables are filled with talcum powder and asbestos. Both talcum powder and asbestos are harmful substances to the human body. Long-term exposure can easily cause human cells to become cancerous. At the same time, the density of the filler formula in the prior art is too high to meet client needs. Contents of the invention [0003] In order to solve the above problems, the present invention provides an elevator balance cable with low density and harmless to human body. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0005] The present invention is an elevator balance cable, which includes a force-bearing element, an outer plastic layer and an outer cladding layer. Several force-bearing elements are ...
