Friction Drive Trolley Conveyor Upper-Side Hook Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional friction drive trolley conveyors are limited in their ability to handle heavy loads due to bending forces acting on brackets and lack of reinforcement, leading to potential deformation and inability to convey large objects like vehicle bodies efficiently.
Innovation Solution
The friction drive trolley conveyor design includes traction purpose engaging means with vertically positioned engaged shafts and pivotally supported hook members, eliminating the need for projecting brackets and allowing direct support, which reduces componentry and costs, enabling safe traction drive even with large forces without bending deformation of the load bar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the joining means uses engaged shaft and hook member at lower side of load bar, then the structure is simple, but large bending force acts on brackets causing inability to convey heavy loads
Solution Approach 1:
The patent moves the joining means from the lower side to the upper side of the load bar, changing the spatial dimension of connection. This dimensional shift allows the engaged shaft and hook member to connect at a position that minimizes bending moments on the load bar, enabling heavy load conveyance without requiring complex reinforcement structures.
Solution Approach 2:
The patent employs symmetric engagement structures at both ends of the load bar, with identical engaged shafts and hook members positioned at corresponding upper locations. This symmetric copying ensures balanced force distribution and eliminates the need for asymmetric reinforcement, maintaining structural simplicity while handling heavy loads.
2Strength
If brackets are reinforced to increase bending rigidity, then heavy load capability improves, but weight and size increase
Solution Approach 1:
The patent extracts and removes the unnecessary brackets from the lower side of the load bar that were previously required to support the joining means. By relocating the joining mechanism to the upper side, the design eliminates redundant structural elements, achieving both heavy load capability and reduced weight without requiring additional reinforcement.
3Device complexity
If joining means is positioned at lower end of load bar, then component arrangement is simple, but bending deformation occurs at end region of load bar
Solution Approach 1:
The patent relocates the joining means from the lower end region to the upper side of the load bar, changing the vertical dimension of connection. This positional change moves the connection point away from the vulnerable end region, preventing bending deformation while maintaining simple component arrangement through symmetric upper-side positioning.

AI summary
A friction drive trolley conveyor has a conveying traveling body provided with a friction drive load bar having traction purpose engaging means at both ends thereof and allows traction drive to be easily conducted without fail even at the time of conveying a heavy object. The traction purpose engaging means is composed of an engaged shaft arranged in the horizontal direction within a vertical notched portion formed at one end of the load bar, a hook member vertically swingably pivotally supported at an intermediate position in vertical height of the load bar at the other end of the load bar and a holding means holding the hook member in an engaged posture or a disengaged posture, and on a traveling route side, a first switching means switching the hook member from the engaged posture to the disengaged posture and a second switching means switching the hook member from the disengaged posture to the engaged posture.
