Elevator Rope Storage Unit with Radial Support Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for storing and installing elevator ropes face challenges, particularly with elastically bendable ropes that are prone to unwinding issues due to bending tension, leading to difficulties in controlling the rope end during unwinding and potential escape from the reel.
Innovation Solution
A rope storage unit comprising a spiral-wound rope reel supported by a body with radially compressing support members, which maintains the rope under bending tension, preventing it from straightening and facilitating controlled unwinding by distributing the support force evenly along the rim, allowing for stable storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the rope is wound in a spiral form and stored on a conventional reel, then the rope can be stored in a compact form, but the bending tension causes the rope to straighten and escape from the reel during unwinding
Solution Approach 1:
The support members are pre-installed on the reel to maintain the spiral shape of the wound rope. This preliminary structural preparation prevents the rope from straightening during storage and transport, and ensures controlled unwinding when needed, eliminating the need for auxiliary means to control the rope end.
2Stability of the object's composition
If the rope is tied against the outer rim of the reel to prevent unwinding, then the rope reel remains stable, but the unwinding process becomes difficult and requires auxiliary means
Solution Approach 1:
The invention extracts and eliminates the need for tying the rope end against the reel. Instead, the support members maintain the spiral shape and provide inherent stability, allowing the rope to be unwound freely without tying or auxiliary control means.
3Device complexity
If the rope is stored without support members, then the storage structure is simple, but the rope cannot maintain its spiral form and becomes difficult to control
Solution Approach 1:
The support members are strategically positioned at specific locations where they most effectively maintain the spiral shape of the rope. This localized support provides the necessary structural stability without requiring a completely complex support system, achieving an optimal balance between simplicity and effectiveness.

AI summary
A rope storage unit includes a rope reel, formed by a rope wound in a spiral form and a support body provided with an inner space inside which the rope reel is positioned supported by the support body. The rope is a rod having a straight form when in rest state and elastically bendable away from the straight form, the rope being under substantial bending tension in the spiral form. The support body includes one or more support members delimiting the inner space and surrounding radially the rope reel. The outer rim of the rope reel radially compresses against the one or more support members as an effect of the bending tension. A method is provided for installing an elevator rope implementing the rope storage unit, as well as to a method for fabricating the rope storage unit.
