End Hose Holder Assembly for Longer Concrete Pump Hose Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concrete pumps without fixed mounting of pipe bends in the joint region between boom arms cannot accommodate an end hose attachment point other than the boom tip, limiting flexibility and length of the end hose.
Innovation Solution
An end hose holder with a foot shell coupling and flange that replaces a concrete line segment and shell coupling in the joint region, allowing for selective attachment of an end hose without altering the kinematics of the delivery line segments, and is designed to match the geometry of standard concrete line segments for easy integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the end hose is attached at the tip of the boom, then the delivery line geometry is simple, but the maximum length of the end hose is limited to 4m due to weight constraints
Solution Approach 1:
The delivery line is divided into multiple segments (first concrete line segment, second concrete line segment) connected by a shell coupling, allowing the end hose to be attached at intermediate points rather than only at the boom tip. This segmentation enables longer end hoses to be used while distributing the weight load along the boom structure.
Solution Approach 2:
A foot shell coupling is introduced as an intermediary component between the two concrete line segments. This foot shell coupling provides an attachment point for the end hose at an intermediate position, acting as a mediator that enables longer hose deployment without requiring the hose to be supported entirely from the boom tip.
2Adaptability or versatility
If the pipe bend is fixedly mounted to enable pivoting for end hose connection, then end hose attachment at joint regions is possible, but the boom cannot be folded compactly for transport
Solution Approach 1:
The foot shell coupling is designed with dynamic characteristics, allowing it to pivot relative to the concrete line segments during operation to enable end hose attachment at joint regions. During transport, the coupling can be positioned in a compact configuration that allows the boom to be folded tightly, thus adapting between operational and transport states.
Solution Approach 2:
The delivery line is segmented into multiple concrete line segments connected by shell couplings, allowing independent positioning and pivoting of each segment. This segmentation enables the pipe bend to pivot for end hose connection while maintaining the overall boom structure's ability to fold compactly during transport.
3Length of moving object
If the second end hose is attached at the joint between last and penultimate boom arm, then the end hose can be longer without overloading the boom, but the delivery line geometry becomes complex
Solution Approach 1:
The foot shell coupling is designed as a universal component that serves multiple functions: it connects two concrete line segments, provides an attachment point for the end hose, and maintains the necessary geometric relationships. This multi-functionality simplifies the overall system compared to designing separate specialized components for each function.
Solution Approach 2:
The foot shell coupling replicates the geometric configuration and connection characteristics of a standard concrete line segment. By copying the established geometry and interface standards, the system maintains simplicity and compatibility while enabling extended end hose attachment at joint regions.
