AI Technical Summary

Technical Problem

The maximum lifting height of the existing 4-host drive structure design is usually 55 meters, which cannot meet the demand for lifting height of 65m in some new escalators projects, resulting in insufficient driving force of the original handrail and unable to meet the high lifting escalator system.

Method used

A double handrail drive structure of an ultra-large height escalator is designed. By setting a handrail drive shaft in the truss and fixing the power connection sprocket symmetrically thereon, the belt bearing is rotatably connected to the handrail drive shaft, the first driving sprocket is fixedly connected to the first handrail friction wheel, and the chain tension structure and the handrail tension structure are used to adjust and drive the handrail belt to realize the synchronous driving of the double handrail.

Benefits of technology

Through the dual handrail drive structure, the lifting height of the escalator can be effectively improved, meet the lifting needs of 65m and above, ensure the stable driving and appropriate tension of the handrail belt, and improve the operating reliability and safety of the escalator.

Abstract

The utility model discloses an upper double-handrail driving structure of an ultra-high escalator, which belongs to the technical field of escalators and comprises a handrail driving shaft arranged in a truss, power connecting chain wheels are symmetrically and fixedly connected onto the handrail driving shaft, and the power connecting chain wheels are connected with the power connecting chain wheels. Mounted bearings are arranged on the sides, away from each other, of the power connecting chain wheels, the mounted bearings are rotationally connected with a handrail driving shaft, and first driving chain wheels are fixedly connected to the two ends of the handrail driving shaft. The chain tensioning structure and the handrail belt tensioning structure are arranged, the chain tensioning structure is designed by reasonably utilizing the space in the truss, the transition transmission requirement and the double-chain tensioning requirement in the double-handrail driving design can be met, and the tensioning degree of the handrail belt can be rapidly adjusted by using the handrail belt tensioning structure; and the requirement for tensioning the handrail belt in a double-handrail driving design is met.
