Hydraulic Cylinder Mounting Plate for Fast Frame-Side Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hydraulic cylinder mountings in mining vehicles are cumbersome and time-consuming due to welding of mounting plates to the vehicle frame, requiring replacement of both plates if one is damaged, and remounting is difficult in confined spaces.
Innovation Solution
A hydraulic cylinder mounting arrangement with an opening in the frame for insertion and removal, using a mounting element with a front plate and ears for attachment, and bolts or screws outside the frame for secure attachment, allowing for easy assembly and disassembly without machining the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mounting plates are welded to the vehicle frame, then the mounting structure is strong and stable, but the replacement and removal of mounting plates becomes time-consuming and laborious requiring machining
Solution Approach 1:
The mounting structure is divided into separate components: the frame with opening, the mounting plate with ears, and the cylinder pin. These segmented parts can be independently assembled and disassembled through the opening, allowing the mounting plate to be replaced without machining the frame while maintaining structural strength through proper connection design.
Solution Approach 2:
The mounting plate is extracted as a separate removable component from the frame structure. By taking out the mounting plate as an independent element that can be inserted and removed through the frame opening, the system allows easy replacement without permanent attachment, resolving the contradiction between strength and ease of repair.
2Manufacturing precision
If both mounting plates are machined as a pair, then the mounting precision is high, but the complexity of replacement increases as both plates must be replaced together
Solution Approach 1:
The mounting plate design with ears and opening creates a universal mounting interface that can accommodate different cylinder pins while maintaining precision. The standardized plate geometry allows any plate to work with any cylinder, enabling replacement of single plates rather than requiring paired replacement, thus reducing replacement complexity while preserving manufacturing precision.
3Strength
If the cylinder is heavy and confined space is available, then the mounting structure must be strong, but the remounting of cylinder pin becomes difficult
Solution Approach 1:
The mounting system utilizes the opening dimension to allow insertion and removal of the cylinder pin from the side rather than requiring removal from the bottom or through complex internal maneuvers. This dimensional approach to assembly allows the heavy cylinder to be positioned and secured more easily while maintaining strong mounting structure.
Solution Approach 2:
The mounting plate with ears acts as an intermediary component between the frame opening and the cylinder pin. This intermediate element facilitates the connection of the heavy cylinder by providing attachment points (ears) that can engage with the pin, making the remounting operation easier while ensuring strong structural connection.

AI summary
A mining vehicle and a cylinder mounting arrangement for a mining vehicle have a frame including at least one hydraulic cylinder mounted to the frame. The cylinder has a cylinder pin arranged for the mounting. The frame has an opening through which the cylinder can be inserted inside the frame and also removed. A mounting element is assembled to one end of the cylinder and the mounting element includes a front plate assembled against the outside of the frame covering the opening at least partially and two ears for the attachment to the cylinder pin. The front plate is fixed to the frame by mounting bolts or screws from the outside the frame.
