External Support Rail for Cleaning Pressurized Paper Machine Drums
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning and maintaining oblong objects, such as paper machine drums, are time-consuming, difficult to assemble, and pose safety risks due to the need for personnel to enter pressurized environments, with existing solutions being cumbersome and hazardous.
Innovation Solution
A fast and safe arrangement for operating devices that includes fixing means, adapters, and an elongated support part adjustable parallel to the oblong object's axis, allowing for assembly outside the object, with telescopic and adjustable components, moving means, and control mechanisms for automated operation, enabling efficient and safe access for cleaning and water cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personnel enter the oblong object for assembly and operation, then direct access and manual operation are enabled, but safety risks increase due to pressurized environments and assembly time increases significantly
Solution Approach 1:
The invention extracts the operator from the hazardous pressurized environment by providing an external operating platform positioned adjacent to the oblong object. The support part with operation device allows cleaning and maintenance operations to be performed from outside the drum, eliminating the need for personnel to enter pressurized spaces while maintaining direct access to the work area through the externally mounted platform
Solution Approach 2:
The support part acts as an intermediary structure between the external operator and the oblong object surface. This mediator provides a safe external platform that bridges the gap between the operator and the work area, enabling operations without direct entry into the hazardous environment while maintaining effective working distance
2Ease of operation
If complex support structures are assembled inside the oblong object, then operational access is achieved, but assembly time increases to several days and device complexity increases
Solution Approach 1:
The support structure is segmented into modular components including the support part, elongated part, and operation device that can be independently assembled and positioned. The fixing means with multiple attachment points allow the structure to be assembled in sections from outside the oblong object, dramatically reducing assembly time from several days to a fraction of that time while maintaining full operational access
Solution Approach 2:
Instead of assembling the support structure from inside the oblong object as in conventional methods, the invention inverts the assembly approach by positioning and assembling the support part from outside the object. The support part is attached to the external surface through fixing means, allowing assembly to be performed from the exterior without requiring entry into the confined internal space
3Adaptability or versatility
If the support structure is made adjustable and versatile for various oblong objects, then adaptability increases, but device complexity increases
Solution Approach 1:
The support part is designed as a universal structure that can be attached to various oblong objects of different sizes and shapes through the fixing means. The elongated part with adjustable positioning and multiple fixing points allows the same basic structure to accommodate different drum diameters and lengths, providing multi-functionality without requiring multiple specialized devices for different object types
Solution Approach 2:
The support structure incorporates dynamic adjustability through movable support parts and repositionable fixing means. The elongated part can be positioned at different locations along the oblong object, and the support part can be adjusted to accommodate varying operational requirements, allowing the structure to adapt to different configurations without increasing fundamental complexity

AI summary
The present invention pertains to an arrangement for facilitating an operation, such as washing or water cutting with an operation device, such as a high-pressure washer, in connection with an oblong object, such as a tube. Specially, maintaining huge washers in the paper industry is time consuming and difficult work to do, which causes costs, because of the maintenance rundown. The arrangement of the present invention comprises at least one adapter arranged to fasten the arrangement to fixing means of the oblong object in question, and an elongated part comprising a support part for an operation device, the elongated part being arrangeable substantially parallel with the longitudinal axis of the oblong object in question by means of the adapter.
