Mobile Concrete Pump Prefabricated Liquid Tank Structural Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile concrete pumps face challenges in handling and leak testing of the large and heavy support structure, which includes a hydraulic tank, due to its size and weight, making it difficult to perform reliable leak tests and repair any leaks that may occur during the process.
Innovation Solution
A prefabricated liquid tank is integrated into the support structure, geometrically adapted to fit within the existing design, allowing for easy handling and leak testing, with load-bearing walls that reinforce the structure and facilitate easy accessibility for repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the support structure is designed as a large welded construction integrating the hydraulic tank, then structural strength and stability are improved, but ease of handling for leak testing and repair deteriorates
Solution Approach 1:
The support structure is divided into modular components: the main support structure (46) and the separate liquid tank (70). This segmentation allows the tank to be handled, tested, and repaired independently while the support structure maintains its structural integrity. The tank can be removed from the support structure for leak testing without dismantling the entire welded construction.
2Area of stationary object
If the liquid tank is integrated as part of the large support structure, then space utilization is improved, but ease of repair deteriorates due to difficult accessibility
Solution Approach 1:
The liquid tank (70) is extracted as a separate component from the support structure (46). It can be taken out for repair or replacement without affecting the support structure. The tank is designed to be accessible within the support structure, allowing repair personnel to easily reach and service it while maintaining efficient space utilization.
3Reliability
If the support structure is designed as a heavy welded construction, then reliability and stability are improved, but ease of manufacture deteriorates due to handling difficulties
Solution Approach 1:
The system is segmented into the support structure (46) and the liquid tank (70) as separate manufacturable components. The support structure can be manufactured as a reliable welded construction, while the tank can be manufactured separately using appropriate fabrication methods. This segmentation makes both components easier to manufacture and assemble while maintaining the reliability of the overall structure.

AI summary
The invention relates to a mobile concrete pump comprising a supporting structure (46) that can be placed directly or indirectly by means of an assembly frame (22) on the running gear (12) of an HGV chassis (10), for receiving functional units that form a support device (38) and a placing boom (36). The placing boom (36) is rotatably mounted on a boom pedestal (44) that is integrated into the supporting structure (46), while the support device (38) comprises two telescopic tubes (54, 56) which are integrated into the supporting structure (46), cross over one another at different heights and have diagonal passages that are open at the front. A respective open space (60, 62) in the supporting structure (46) lies below the upper and above the lower telescopic tube (54, 56), each open space being separated from the neighbouring telescopic tube by an intermediate base (58). A feature of the invention is that a pre-fabricated liquid tank (70) is inserted into at least one of the open spaces (60), the outer contour of said tank being geometrically adapted to the supporting structure (46) and said tank supplementing and reinforcing the supporting structure (46).
