Large-load cargo elevator hanging system with traction ratio being 6:1

Abstract

The invention discloses a large-load cargo elevator hanging system with the traction ratio being 6:1. The large-load cargo elevator hanging system with the traction ratio being 6:1 comprises a counter-weight assembly, and is characterized in that a machine room bearing steel beam is designed into a #-shaped structure or a structure of a Chinese character 'tian'; a rope head steel beam and a host steel beam arranged in parallel and a counter-weight steel beam and a guiding steel beam arranged in parallel are included; three bridge frame structures are arranged and comprises a main bridge frameand two front and back auxiliary bridge frames; the lift car load is hung on the front and back auxiliary bridge frames; and a single traction steel wire rope is made to form four hanging strands on one auxiliary bridge frame, and form two hanging strands on another auxiliary bridge frame. The range in which a large-load cargo elevator host adopts a gearless synchronous host is wider; the load requirement of a main shaft is lowered, and the using requirement of a large-load cargo elevator is met; the waste oil environment pollution problem is solved; and stress is balanced and stable, and elevator running is more stable; and the running noise is low.

Description

technical field [0001] The invention relates to elevator manufacturing technology, in particular to a large-load cargo elevator suspension system with a traction ratio of 6:1. Background technique [0002] The elevator traction suspension system in the prior art all uses 2 n : 1 (n=1, 2, 3, 4) structural form design, as the patent publication number is CN104192674A, a kind of elevator traction suspension system, comprises some work wheels and the traction suspension cable that is wound on these work wheels, One type of working wheel is a traction wheel, and the other is a guide wheel that moves with the car and the counterweight. The traction suspension cable cooperates with one type of working wheel with axial limit full restraint, and the other type of working wheel A freely constrained fit that can slide axially is used. Suitable for use in various elevator systems with a winding ratio of 2:1 or 4:1. Another example is that the patent publication number is CN104192675A...

AI Technical Summary

Problems solved by technology

Since the load of the main shaft of the synchronous main engine is much smaller than that of the asynchronous main engine with the same rope-winding suspension ratio, for large-load freight elevators (load > 5000kg), the traction main engine adopts a synchronous main engine, and the rope-winding suspension ratio is usually 2n:1(n=1,2,3,4) cannot fully meet the technical requirements

Rope suspension ratios of 2:1 and 4:1 lead to high cost of traction main engine and low product technical design value; while rope suspension ratios of 8:1 and 16:1 are too complicated for rope suspension, which is not conducive to the overall product structure layout , and the product speed is difficult to improve, the operating efficiency is low, and it is not suitable for product marketing
