People Transport Hoisting Rope Transfer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing people transportation systems require arranging two consecutive hoisting ropes next to each other and transversely adjustable coupling devices to facilitate vehicle transfer, which complicates the system design and operation.
Innovation Solution
The system arranges two successive hoisting ropes in a straight line, with vehicles equipped with clamping devices at a distance along the longitudinal direction, and a control device, such as a control rail with pivotable and height-adjustable wedge-shaped control ramps, to manage the coupling and uncoupling of vehicles between ropes without needing adjacent end regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two consecutive hoisting ropes are arranged next to each other with transverse adjustable clamping devices, then vehicle transfer between ropes is enabled, but the system complexity increases due to required transverse adjustments and adjacent end region arrangement
Solution Approach 1:
Instead of arranging hoisting ropes side by side and adjusting clamping devices transversely, the invention inverts the arrangement by placing ropes in longitudinal succession. The clamping devices remain fixed in the longitudinal direction, eliminating the need for transverse adjustment mechanisms while maintaining vehicle transfer capability.
Solution Approach 2:
The invention extracts and eliminates the transverse adjustment mechanism from the system. By changing the rope arrangement from lateral to longitudinal, the complex transverse adjustment capability is removed entirely, simplifying the overall system design while preserving the essential function of vehicle transfer.
2Ease of operation
If clamping devices are made transverse adjustable to facilitate vehicle transfer, then coupling between ropes is simplified, but the manufacturing and maintenance difficulty increases
Solution Approach 1:
Rather than making clamping devices adjustable in the transverse direction to accommodate side-by-side rope arrangement, the invention inverts the approach by arranging ropes longitudinally. This allows clamping devices to remain fixed and simple in structure, greatly simplifying manufacturing while maintaining operational ease through the longitudinal transfer mechanism.
3Device complexity
If hoisting ropes are arranged in a straight line with fixed clamping devices, then system design is simplified, but vehicle transfer control becomes more complex
Solution Approach 1:
The control system is pre-programmed with the sequence of uncoupling and recoupling operations. As the vehicle approaches the transfer zone, the control device automatically initiates the uncoupling of the first clamping device from the first rope, followed by coupling to the second rope, and subsequent uncoupling/recoupling of the second clamping device. This preliminary programming of the control sequence manages the complexity of coordinated operations without requiring complex real-time control mechanisms.
Solution Approach 2:
The control device acts as an intermediary that coordinates the timing and sequence of clamping device operations. It manages the complex transfer process by systematically controlling each uncoupling and coupling action in the correct sequence, bridging the simplicity of fixed clamping devices with the requirement for coordinated transfer operations.
