Mining Machine Towing Hook With Integrated Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing towing hooks for heavy mining machines are complex and require additional structures in the machine frame, making them difficult to maintain and inefficient in space usage, especially in emergency situations where a simple and space-efficient solution is needed to transmit towing forces effectively underground.
Innovation Solution
A towing hook with a mainly straight construction, featuring a bent portion for connecting towing tools and a cylindrical rod with an intermediate part mounted in the machine frame, allowing for efficient force transmission and minimizing external components, including stopper elements to prevent hook displacement and springs for easy return to neutral position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complex towing hook construction with additional structures in the machine frame is used, then the towing force transmission capability is improved, but the device complexity and maintenance difficulty increase
Solution Approach 1:
The towing hook is divided into distinct functional segments: a hook portion for connecting towing tools, a rod portion for force transmission, and an intermediate portion for mounting. This segmentation allows each part to be optimized independently while simplifying the overall construction and reducing maintenance requirements.
Solution Approach 2:
The towing hook is designed as a multi-functional component that can be mounted in a through-hole of the machine frame while transmitting towing forces effectively. The single integrated structure serves both as a connection point and a force transmission element, eliminating the need for additional separate structures in the frame.
2Ease of operation
If a traditional towing hook with multiple external components is used, then the towing functionality is achieved, but the space efficiency and number of external parts increase
Solution Approach 1:
The hook portion, rod portion, and intermediate portion are merged into a single integrated towing hook component. This consolidation reduces the number of separate external parts while maintaining full towing functionality, thereby improving space efficiency and reducing maintenance needs.
3Reliability
If a towing hook requiring frequent maintenance is used, then the towing capability is maintained, but the loss of time for maintenance increases
Solution Approach 1:
The towing hook design incorporates stopper elements that prevent displacement and springs that enable easy return to neutral position, allowing the component to maintain its functionality automatically without requiring frequent external maintenance or adjustment.

AI summary
A towing hook arranged on a mining machine, with a first end having a bent portion to allow a towing tool to be connected and a second end having a cylindrical rod. An intermediate part is located between the first and the second end. The towing hook is arranged to be mounted in a through hole in a frame of a machine in order for the first and second ends to be positioned on different sides of the machine frame. The intermediate part is mounted partly in the through hole of the frame, and wherein the longitudinal axis of the cylindrical rod is generally parallel with a longitudinal axis defined through the towing hook representing the force transmitting direction when connecting the towing tool to the bent portion.
