Torsion Holder Locking Mechanism for Conveyor Scraper Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor belt scrapers lack an easy and effective method for aligning the torsion holder with the base, leading to potential misalignment and inefficiencies in belt scraping.
Innovation Solution
A conveyor belt scraper design featuring a base with retention formations, a torsion holder with a belt scraping edge that is rotatable relative to a mounting member, and a locking member that restricts rotational movement, allowing for resilient deformation to maintain alignment under force, using a resiliently deformable material like rubber or polyurethane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the torsion holder is made rigid to maintain stable alignment with the base, then alignment stability is improved, but the ability to deflect under force is reduced
Solution Approach 1:
The torsion holder is designed with a resiliently deformable locking member that allows dynamic adjustment between a locked aligned state and a deflected state under force, enabling the holder to adapt its rigidity based on operational conditions
Solution Approach 2:
The locking member's material properties are selected to provide resilient deformation, allowing it to change its effective rigidity parameter - remaining rigid when locked for alignment stability, but allowing controlled deflection when force is applied to the scraper edge
2Reliability
If the locking member is made rigid to prevent rotational movement, then alignment restriction is improved, but the ability to absorb force is reduced
Solution Approach 1:
The locking member is designed with resilient material properties that allow it to change its mechanical behavior - providing rigid alignment restriction under normal conditions, but allowing elastic deformation to absorb excessive forces applied to the scraper edge
3Strength
If the torsion holder allows free rotation to accommodate force, then force absorption is improved, but alignment precision is reduced
Solution Approach 1:
The system transitions from a static locked state with high alignment precision to a dynamic deflected state under force, where the resilient locking member allows controlled rotation while maintaining functional alignment
Solution Approach 2:
The resilient locking member acts as a pre-designed cushion that absorbs and redistributes forces applied to the scraper edge, preventing sudden misalignment while allowing controlled deflection
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 continuous and efficient belt scraping by allowing the scraper edge to deflect slightly under force, maintaining effective contact with the conveyor belt surface while preventing damage, thus optimizing scraping performance.
Implementation Method 1
The locking member is operable to deform and allow a limited degree of rotational movement of the torsion holder arm, relative to the base, to take account of forces exerted on the scraping edge by material on a conveyor belt which is being cleaned and, thereafter, as the deforming force is released to act on the torsion holder arm and thereby restore the arm to a correct belt scraping position.
