Nine-strand steel core steel wire rope online tensioning production line equipment and technology for ultra-high-speed elevators

Abstract

An on-line stretch-draw production line equipment and technology of nine-strand steel cored wire ropes for an ultra-high-speed elevator are disclosed, and the equipment is composed of a pay-off device, a rope stranding set, a stranding die base set, a post deformer, a three-dimensional sizing device, a broken wire monitoring device, a pre-tension control system, a second traction system and a spooling device. The rope stranding set is a nine-wheel tubular machine, a single-strand pay-off device is mounted on the tail of the tubular machine, the pay-off mode and the tension control method of the pay-off device are identical to a strand pay-off device in a machine body, metal core paying off is arranged on a first frame of a handpiece, consistency of tension is guaranteed, stranding stress of steel wire ropes is reduced, and the fact that the structure of the steel wire ropes and the structure of metal cores are damaged due to the fact that the metal cores are arranged on the tail is avoided. Through the adoption of the technology, rope combining and pre-tension of the nine-strand metal core steel wire ropes are completed on line at one time, production efficiency is improved, residual stranding stress of the metal core steel wire ropes is distributed evenly, and quality of products is improved.

Description

Technical field [0001] The invention relates to a nine-strand steel core steel wire rope online tensioning production line equipment and process for ultra-high-speed elevators, and belongs to the technical field of metal product production equipment and processes. Background technique [0002] With the acceleration of my country's urbanization process and the rapid increase in the number of high-rise buildings, the domestic demand for high-speed and ultra-high-speed elevators has increased sharply, and the demand for high-speed and ultra-high-speed elevator wire ropes has also increased accordingly. However, the current domestic market for general-grade elevator wire ropes exceeds demand, and the production capacity and technical level of high-speed elevator wire ropes are insufficient. They still need to be imported from Switzerland, South Korea, France, and Germany. Although elevator companies have higher requirements for high-speed and ultra-high-speed elevator wire ropes, due...
