Compensating Wire Bundle Storage for Jump Lifts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jump lifts are limited to a maximum lifting height of 300 meters and operation speed of 3 m/s, which is insufficient for super high-rise building construction due to constraints in compensating chain design and safety regulations.
Innovation Solution
A compensating wire bundle storage device for jump lifts, comprising wire drums and a clamping device, allows for selective storage and release of a compensating rope or chain, enabling increased lifting height and speed by attaching the device to the car and counterweight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compensating chain is used to suspend the car and counterweight, then the lift can operate safely within existing regulations, but the maximum lifting height is limited to 300 meters and maximum speed to 3 m/s
Solution Approach 1:
The compensating device is divided into multiple wire bundles, each wound on separate wire drums. The wire bundles can be independently managed and released, allowing the system to achieve greater lifting heights by progressively releasing multiple bundles rather than relying on a single long compensating chain.
Solution Approach 2:
The wire drums are designed to rotate and release wire bundles dynamically during the lifting process. The compensating wire bundle clamping device can releasably clamp the wire bundles, allowing the system to adapt the compensating length as the building height increases, enabling lifting heights exceeding 300 meters.
2Reliability
If a compensating chain is used to suspend the car and counterweight, then the lift structure is simple and reliable, but the maximum operation speed is limited to 3 m/s
Solution Approach 1:
The invention changes the physical parameters of the compensating element from a traditional compensating chain to compensating wire bundles. Wire bundles have different mechanical properties including higher strength-to-weight ratio and better flexibility, which allow for higher operation speeds while maintaining structural reliability and safety.
3Length of moving object
If the lifting height is increased to construct super high-rise buildings over 300 meters, then the construction capability is improved, but the existing compensating chain design becomes insufficient
Solution Approach 1:
The wire bundles are pre-wound on wire drums in a compact, organized manner before use. This preliminary arrangement allows for controlled release and deployment as the building height increases, managing the complexity of handling long compensating elements through pre-organized storage and systematic deployment.
Solution Approach 2:
The wire drums act as intermediary devices between the compensating wire bundles and the lift car. They provide a mechanism for controlled release, storage, and management of the wire bundles, simplifying the overall system by mediating the interaction between the long compensating elements and the moving car.
4Length of moving object
If a compensating wire bundle storage device is added to increase lifting height, then the lifting height capability is improved, but the device complexity increases
Solution Approach 1:
The wire drums serve multiple functions: they store the compensating wire bundles in a compact form, control the release of wire during lifting, and can be repositioned or adjusted as needed. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing device complexity while achieving increased lifting height capability.
