Screw Pile Loading Assembly for Safer Automated Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual mounting of screw piles onto drilling equipment is labor-intensive, time-consuming, and poses safety risks, especially in remote work sites where multiple piles need to be installed, such as in solar energy installations, incurring significant labor costs.
Innovation Solution
A pile installation apparatus with a mast, carriage and drive assembly, and clamping mechanism that allows for automated loading and installation of screw piles, eliminating the need for manual labor, featuring a vehicle mount, rotational drive, and clamping assembly to secure the pile during rotation and insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual mounting of screw piles is used, then labor flexibility is maintained, but productivity is low and safety risks increase
Solution Approach 1:
The apparatus enables self-service operation where the automated mounting mechanism performs pile loading and positioning without requiring manual handling. The system serves itself by using the vehicle's own hydraulic system to actuate the mounting mechanism, eliminating the need for external labor while maintaining operational capability.
Solution Approach 2:
The patent replaces the manual mechanical handling system with an automated hydraulic mounting mechanism. The hydraulic actuator substitutes for human physical effort in gripping, lifting, and positioning the screw piles, thereby increasing productivity while reducing manual labor requirements.
2Loss of time
If manual mounting process is used, then equipment simplicity is maintained, but time consumption increases
Solution Approach 1:
The mounting apparatus is segmented into distinct functional components: a carriage assembly for movement along the mast, a gripping mechanism for securing piles, and a hydraulic actuation system. This segmentation allows each component to perform its specific function efficiently, reducing overall mounting time while keeping the added complexity manageable through modular design.
Solution Approach 2:
The carriage and drive assembly serves multiple functions: it transports piles vertically along the mast, positions them for insertion, and provides the gripping force for secure mounting. This multi-functionality reduces the need for separate devices for each operation, thereby reducing time loss without proportionally increasing device complexity.
3Ease of operation
If manual labor team is deployed, then safety risks are managed, but operational costs increase
Solution Approach 1:
The patent replaces manual handling operations with an automated hydraulic mounting mechanism that securely grips and positions screw piles. This substitution eliminates the safety risks associated with manual labor while reducing operational costs by requiring only one operator to control the automated system, rather than a team of laborers.
4Extent of automation
If automated mounting is implemented, then labor requirements are reduced, but device complexity increases
Solution Approach 1:
The automated mounting mechanism is designed to be self-contained, using the vehicle's existing hydraulic system to actuate the mounting operations. The system serves itself by leveraging available onboard resources rather than requiring external complex support systems, thereby achieving high automation while limiting the increase in overall device complexity.

AI summary
A pile installation apparatus and method of use thereof is provided for loading and installing a pile into an underlying ground surface. In one form, the pile installation includes: a mast; a vehicle mount for mounting the mast to a support vehicle; a carriage and drive assembly rotatably coupled to the mast and configured for vertical movement along the mast, said assembly including a rotational drive and drive shaft for mounting of a drive end of the pile thereon. The carriage and drive assembly configured to be rotatable relative to the mast between a loading position for loading a non-vertically oriented pile onto the drive shaft and an operable position for driving the pile into the underlying ground surface.
