Concrete Bucket Washing Tower Guide Pads Centering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing structures for concrete skips are unsuitable for heavy loads, posing safety risks and making it difficult to wash due to their design, which includes protruding bars that increase space requirements and pose hazards, and are not compatible with standard skips without modification.
Innovation Solution
A washing tower with a support structure formed by metal tubes, featuring two floors with horizontal lateral support tubes and guide pads with rollers for centering and supporting the skip, reducing bulk and hazards, and allowing for precise positioning without external bars, along with a chute for water management and recycling, and a compact one-piece assembly for easy transport and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If protruding horizontal bars are added to standard skips to enable positioning on washing towers, then skipping adaptability is improved, but device complexity and safety hazards increase
Solution Approach 1:
Instead of modifying the skip with protruding bars to achieve positioning, the invention inverts the approach by providing recessed cradles in the washing tower that receive the skip's existing features. This reverses who needs to be modified - the washing tower adapts to the skip rather than the skip adapting to the tower.
Solution Approach 2:
The cradle structure serves multiple functions: it centers the skip horizontally, provides vertical support, and accommodates various skip types without modification. The universal design allows different skip configurations to be processed on the same washing tower.
2Measurement precision
If protruding bars are used for skip centering, then positioning precision is improved, but safety hazards and space requirements increase
Solution Approach 1:
The skip nests into the cradle structure during positioning, with the cradle's horizontal tubes receiving the skip's body. This nested arrangement achieves precise centering while keeping all components contained within the washing tower footprint, eliminating protruding hazards.
3Ease of manufacture
If a support structure is designed for light loads, then ease of manufacture is improved, but load bearing capacity deteriorates
Solution Approach 1:
The support tubes are pre-assembled with cradle components before final installation on the washing tower. This preliminary assembly allows for quality control and proper fit-up while maintaining manufacturing simplicity, ensuring the structure can handle heavy loads without requiring complex post-installation adjustments.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient washing of concrete skips without modifying existing skips, reducing space requirements, and ensuring operator safety by stabilizing the skip with rollers, while minimizing external water usage through internal recycling.
Implementation Method 1
each receiving guide pads provided to surround the bucket by constituting the support of two of the inclined faces and by providing support and wedging of this bucket
Implementation Method 2
the inclined lower faces of this bucket sliding on the skids to effect its centering

AI summary
A washing tower designed to receive a concrete skip (2) for washing, the skip body having lower faces (6) inclined downwards towards the center and terminating below in a concrete discharge opening closed by a trapdoor operated by a lever (8), said washing tower comprising a load-bearing structure formed by metal tubes and having, at its upper part, means for supporting the skip. The tower is characterized in that it comprises two levels (38, 42) and in that the floor of the second level (42) has an opening (58) framed by horizontal lateral support tubes (46) which receive guide pads (48) designed to surround the skip (2), forming the support for two of the inclined faces (6) and providing support and stabilization for the skip. Applicable particularly on construction sites for washing such skips.
