Modular Vibratory Conveyor Assembly Using Bolted Subassemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibratory conveyors in hazardous and confined installations face significant challenges due to the time and expense required for repair, as conventional welding and cutting methods are hazardous and disruptive, and the large size of the equipment makes on-site servicing difficult.
Innovation Solution
A modular vibratory apparatus is fabricated into individual subassemblies that are transported to the installation site and assembled using bolting techniques, eliminating the need for welding and allowing for easier disassembly and replacement, thus facilitating safer and more efficient maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional welding and cutting methods are used to repair vibratory conveyors, then structural strength is maintained, but repair time and expense increase significantly
Solution Approach 1:
The vibratory conveyor is divided into modular subassemblies that can be independently removed and replaced. This segmentation allows the failed module to be quickly swapped out without time-consuming welding or cutting operations, directly reducing repair time while maintaining structural integrity through standardized connection interfaces.
Solution Approach 2:
The connection method transitions from permanent welding to dynamic, reversible bolting. This allows the system to be quickly reconfigured and repaired by removing and replacing bolted subassemblies, eliminating the time loss associated with welding operations while maintaining adequate structural strength for the application.
2Strength
If conventional welding and cutting methods are used for repair, then structural integrity is maintained, but hazardous conditions and expense increase
Solution Approach 1:
By segmenting the conveyor into replaceable subassemblies connected by bolts, the design eliminates the need for hot work (welding and cutting) in hazardous environments. This removes the source of ignition hazards while maintaining structural integrity through the bolted modular construction.
Solution Approach 2:
The invention replaces thermal processing methods (welding and cutting) with mechanical fastening (bolting). This substitution eliminates the harmful thermal effects and ignition risks associated with welding, particularly in explosive or hazardous duty environments, while maintaining adequate structural strength.
3Strength
If the conveyor is designed as a single integrated unit, then structural strength is maximized, but ease of repair deteriorates
Solution Approach 1:
The conveyor is divided into functional subassemblies (hopper, feeder, conveyor sections) that are connected through standardized bolting interfaces. This segmentation enables individual subassemblies to be removed and replaced without affecting the entire structure, greatly improving ease of repair while maintaining overall structural strength through the modular design.
4Strength
If welding is used to attach subassemblies, then structural strength is improved, but adaptability and ease of disassembly deteriorate
Solution Approach 1:
The connection system transitions from static, permanent welding to dynamic, reversible bolting. This allows subassemblies to be easily assembled and disassembled as needed, providing adaptability for maintenance, reconfiguration, or relocation, while the bolted joints maintain sufficient structural strength for the conveyor's operational requirements.

AI summary
A method of installing a vibratory conveyor into a confined space includes fabricating a modular vibratory apparatus as individual subassemblies, comprising at least first and second side wall subassemblies, first and second end wall subassemblies, at least one cross-member subassembly, a mounting bracket subassembly, a drive subassembly, and a liner subassembly. The method also includes transporting the individual subassemblies to an installation site as separate subassemblies, and attaching the individual subassemblies to each other to define an assembled modular vibratory apparatus using a bolting technique at the installation site.
