Dynamic Energy Flow Regulation in Pile Foundation Carrier Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for power management in pile foundation processes, such as grab drilling with a casing machine/pipe lathe, suffer from quasi-static energy flow regulation, leading to inefficient energy consumption and delayed work processes due to inconsistent energy distribution between the carrier machine and the attachment.
Innovation Solution
Implementing a dynamic control system that regulates energy flow between the carrier machine and the attachment based on current and future power requirements, optimizing energy utilization by adjusting energy supply according to the specific power needs of each machine during different work steps, and synchronizing the casing process with borehole excavation.

Engineering Contradiction Analysis
1Ease of operation
If quasi-static energy flow regulation is used, then the system is simple to operate, but energy consumption increases and work process is delayed
Solution Approach 1:
The patent implements dynamic energy flow regulation that continuously adapts the energy distribution between carrier machine and attachment based on real-time power requirements. The control system dynamically adjusts energy allocation during different work steps (digging, lifting, casing insertion) rather than using fixed quasi-static regulation, thereby optimizing energy utilization and reducing overall consumption.
Solution Approach 2:
The control system incorporates feedback mechanisms that monitor the power requirements of both the carrier machine and attachment. Based on this feedback, the system automatically adjusts the energy flow distribution to match actual demand, preventing both energy shortages that cause delays and excess energy provision that increases consumption.
2Device complexity
If quasi-static energy flow regulation is used, then the control system is simple, but work process efficiency decreases
Solution Approach 1:
The control system transitions from static to dynamic regulation, continuously adapting energy distribution based on the varying power requirements during different phases of the pile foundation process. This dynamic approach optimizes the coordination between digging and casing insertion operations, thereby improving overall productivity despite increased control complexity.
Solution Approach 2:
The system changes the energy flow parameters dynamically based on detected work conditions. By adjusting energy allocation parameters in response to varying power demands of the carrier machine and attachment, the system optimizes work process efficiency without requiring overly complex control architecture.
3Speed
If excess energy is provided to the attachment, then the attachment can perform work faster, but overall energy consumption increases
Solution Approach 1:
The control system dynamically adjusts the energy flow parameters to the attachment based on real-time assessment of power requirements. During phases where the attachment benefits from higher power (such as during active casing insertion), the system increases energy allocation to improve work speed. During phases where the carrier machine requires more power or the attachment is idle, the system reduces energy allocation, thereby optimizing the balance between attachment speed and overall energy consumption.
