Hinged Arch Locking Mechanism for Concrete Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thick matter conveying devices, such as concrete pumps, have complex structures with separate locking mechanisms for folding and rotating movements of the folding arch, leading to economic disadvantages and safety risks due to quick wear and potential injury.
Innovation Solution
A folding arch mechanism that integrates both rotational and pivoting movements into a single locking component, reducing the number of components and complexity, and utilizing a frictional connection and toggle lock for secure self-locking, allowing for easier access and reduced costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate locking mechanisms are used for folding and rotating movements, then each movement can be securely locked, but the device complexity increases and manufacturing costs rise
Solution Approach 1:
The patent combines two separate locking mechanisms into a single integrated locking device that simultaneously locks both the folding movement (about the pivot axis) and the rotating movement (about the rotation axis). The locking device includes a locking element that can engage with locking surfaces on both the folding arch and the holder, achieving dual locking function with one mechanism.
Solution Approach 2:
The locking device is designed as a multi-functional component that performs multiple locking functions. It can lock the folding arch in its folded position and also lock the holder in its rotated position, making a single device serve multiple purposes and eliminating the need for separate locking mechanisms.
2Ease of operation
If separate locking mechanisms are used for folding and rotating movements, then each movement can be independently controlled, but the manufacturing costs increase
Solution Approach 1:
The patent merges two separate locking mechanisms into one integrated device, reducing the total number of components that need to be manufactured, assembled, and maintained. This single locking device controls both folding and rotating movements, lowering manufacturing costs while maintaining operational independence through its design that allows sequential or independent engagement of the two locking functions.
3Reliability
If multiple locking mechanisms are used, then each movement can be securely locked, but the wear and potential injury risk increase
Solution Approach 1:
The patent combines multiple locking mechanisms into a single locking device with fewer moving parts and locking elements. By reducing the number of separate locking mechanisms from two to one, the patent minimizes the number of contact surfaces subject to wear and the number of potential failure points, thereby reducing both wear and injury risk while maintaining secure locking of both movements.
4Device complexity
If a common locking mechanism is used for both movements, then the device complexity is reduced, but the ability to independently control each movement may be compromised
Solution Approach 1:
The integrated locking device is designed with separate locking elements or engagement points for the folding arch and the holder, allowing each movement to be locked independently. The device can engage the folding arch first, then engage the holder, or vice versa, providing independent control while maintaining a single unified locking mechanism that reduces overall device complexity.

AI summary
The invention relates to a viscous material conveying device (10), in particular for conveying concrete, comprising at least one conveying cylinder by means of which viscous material can be conveyed from a viscous material collection container (12) into a conveying line (14). The conveying line includes a pivotable hinged arch (20) which is mounted externally on a rear wall (16) of the viscous material collection container and, in the folded or closed state, covers a conveying opening formed in the rear wall. According to the invention, the hinged arch is rotatable about a horizontal axis of rotation (18) and pivotable about a pivot axis (19) spaced apart from the axis of rotation and can be locked against both rotational and pivotal movements simultaneously by means of a common locking mechanism. The invention further relates to a hinged arch for a viscous material conveying device according to the invention.
