Grading Machine Stand for Drawbar and Moldboard Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling and maintenance of heavy, complexly shaped drawbars and moldboards on grading machines are challenging due to their size and weight, leading to safety concerns and extended downtime for maintenance and transportation.
Innovation Solution
A stand system comprising a base frame and component support units is designed to securely hold and align drawbars and moldboards, allowing for efficient removal, installation, and transportation using forklifts and cranes, balancing the load to minimize torque and enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drawbar and moldboard are made from strong metal and large size to provide desired contour control, then the grading machine can perform its function effectively, but the components become difficult to handle, transport and service
Solution Approach 1:
A stand is introduced as an intermediary device to support and hold the drawbar and moldboard during handling, transportation, and servicing. The stand provides a stable platform that eliminates the need for direct manual handling of the heavy components, thereby resolving the contradiction between functional performance and handling ease.
2Reliability
If the drawbar is made large and complex shaped to provide desired contour control, then the grading machine can achieve its operational goals, but the center of gravity is not centrally located making it difficult to handle
Solution Approach 1:
The stand serves as a mediator that supports the complex-shaped drawbar, distributing its weight and providing a stable base. This intermediary structure compensates for the non-central center of gravity, making the component easier to handle and position during servicing.
3Reliability
If the drawbar and moldboard are removed and serviced periodically, then the grading machine can maintain operational reliability, but the grading machine is out of service for a considerable period of time
Solution Approach 1:
The stand enables efficient removal and installation of the drawbar and moldboard by providing a stable support platform that facilitates quick transfer of components. This intermediary device reduces the time required for servicing operations, thereby minimizing the downtime the grading machine is out of service.
4Adaptability or versatility
If the drawbar and moldboard are transported separately during servicing, then the components can be serviced at different locations, but the transportation becomes complex and time-consuming
Solution Approach 1:
The stand allows the drawbar and moldboard to be transported together as a single unit rather than separately. By combining these components on one support structure, the transportation process becomes simpler and faster, reducing the overall time loss while maintaining the flexibility to service at different locations.

AI summary
A stand is disclosed for supporting a moldboard and a drawbar of a grading machine. The stand may comprise a base frame and a component support unit. The said stand may be configured to support the moldboard, and the component support unit may be configured to support at least a portion of the drawbar. The base frame and the component support unit may be configured to: (a) support a substantial portion of the moldboard above the base frame; and (b) support a substantial portion of the drawbar above the base frame and the moldboard when the moldboard is supported on the stand.
