Anti-Falling Device Locking Mechanism for H Beam Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-falling devices can operate unsafely if the controlling members are pressed carelessly, leading to disengagement of the single-direction toothed member from the ratchet teeth, compromising safety.
Innovation Solution
The anti-falling device incorporates a support rod with ratchet teeth, two locking jaws, and inserting bolts, where the controlling member has a lock bolt that engages with ratchet teeth when in the locking position, and is limited by the inserting bolts to prevent accidental disengagement, ensuring safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controlling member is designed to be easily pressed for operation, then the ease of operation is improved, but the safety deteriorates due to accidental disengagement
Solution Approach 1:
The patent applies preliminary anti-action by designing the inserting bolt mechanism that prevents accidental pressing of the controlling member before such pressing can cause unsafe disengagement. The inserting bolt acts as a preliminary protective measure that counteracts the potential harmful action of careless pressing, allowing easy operation while maintaining safety.
Solution Approach 2:
The inserting bolt serves as an intermediary element between the controlling member and the external environment. It mediates the interaction by providing a physical barrier that prevents accidental activation while allowing intentional operation through proper removal of the inserting bolt, thus resolving the contradiction between ease of operation and safety.
2Reliability
If the lock bolt is designed to engage firmly with ratchet teeth, then the reliability is improved, but the ease of operation deteriorates due to difficulty in disengagement
Solution Approach 1:
The patent segments the locking mechanism into distinct functional components: the lock bolt for reliable engagement with ratchet teeth, the controlling member for operation, and the inserting bolt for safety protection. This segmentation allows each component to perform its specific function optimally - the lock bolt provides firm engagement for reliability, while the controlling member and inserting bolt mechanism enable controlled operation.
Solution Approach 2:
The patent applies dynamics by designing the controlling member to swing between locking and unlocking positions, and by using the removable inserting bolt to dynamically change the state of the mechanism between locked and operable states. This dynamic design allows the system to transition between reliable locking and easy operation as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures safe and easy operation by preventing accidental disengagement of the lock bolt from the ratchet teeth, maintaining the locking position and securely clamping the H beam, thereby enhancing worker safety.
Implementation Method 1
the spring is defined between the fixing mount and the controlling member so as to push the controlling member to fix at the locking position
Implementation Method 2
The two inserting bolts are inserted into the two apertures and the receiving orifice so as to limit the controlling member at the locking position
Implementation Method 3
when the controlling member is located at the locking position, the lock bolt engages with one of the plurality of ratchet teeth
