Excavator Position Fixture for Rod Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional excavators face difficulties in aligning and connecting new rods with previously inserted rods due to severe vibration, making the assembly process inconvenient and challenging, especially when dealing with long rods used for deep hole excavation.
Innovation Solution
An excavator design incorporating a position fixture with a base member, support plate, and locking unit that slidably attaches to the leader, allowing the first rod to be fixed without vibration, ensuring accurate alignment and connection with the second rod, using a support groove and locking mechanism to stabilize the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a new rod is assembled with the head for deep hole excavation, then the rod length is extended to reach deeper depths, but severe vibration occurs making alignment and connection difficult
Solution Approach 1:
A position fixture is introduced as an intermediary device between the head and the rod assembly process. The position fixture includes a base member that slides along the leader and a support plate that supports the rod, acting as a mediator to stabilize the rod during connection operations and eliminate vibration-induced alignment difficulties
Solution Approach 2:
The position fixture is positioned and activated before the rod connection operation begins. The base member slides to the appropriate position on the leader, and the support plate is prepared to support the rod, ensuring the rod is stabilized in advance before alignment and connection tasks are performed

AI summary
An excavator is provided, in which the excavator includes a head that is slidably mounted on a leader, and a position fixture assembly slidable along the leader via the head. The position fixture includes a support plate including a groove in it top surface, with a first rod slidable within the groove. The position fixture also including a locking unit that serves to engage a base member, allowing the base member to be elevated when the head is elevated.
