Drilling Machine Anchoring Device With Sliding Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drilling machines for hard soil excavation struggle to maintain a stable drilling path without altering their transverse position, leading to inaccuracies and skewing of the drilling path during anchoring.
Innovation Solution
The drilling machine incorporates a sliding connection between the anchor pads and actuator device, allowing the anchor pads to deploy and adjust relative to the frame and drilling module without changing the transverse position, ensuring the drilling module remains stationary during anchoring, and includes guide devices to enhance force distribution and robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anchor pads are deployed to hold the drilling machine stationary, then anchoring reliability is improved, but the transverse position of the drilling machine changes causing drilling path skew
Solution Approach 1:
The anchoring system is segmented into movable anchor pads that can deploy independently relative to the drilling module. The anchor pads are separated from the main frame through a movable connection, allowing them to be deployed without moving the drilling module position.
Solution Approach 2:
The connection between the anchor pads and the frame is made dynamic and movable rather than fixed. The actuator device can move relative to the frame in a direction parallel to the anchor pad deployment direction, enabling the anchoring system to adapt its configuration without altering the drilling module's transverse position.
2Manufacturing precision
If the drilling machine position is modified to correct the drilling path, then drilling path accuracy is improved, but the machine is no longer centered in the excavation
Solution Approach 1:
The movable connection acts as an intermediary between the anchor pads and the drilling module. This intermediary allows the anchor pads to move and deploy while the drilling module remains stationary, decoupling the anchoring function from the positioning function.
3Reliability
If anchor pads are deployed to recenter the drilling machine, then anchoring reliability is improved, but the drilling path is skewed again
Solution Approach 1:
The dynamic movable connection allows the anchor pads to deploy and adjust their position independently. This dynamic configuration enables the system to achieve reliable anchoring while maintaining the drilling module's original centered position, preventing path skew.

AI summary
A drilling machine for drilling ground in a vertical direction, the machine including: an anchor module having front and rear faces, the anchor module including an anchor device having front and rear anchor pads that are deployable in a deployment direction, to bear against walls of the excavation to hold the anchor module stationary in the ground. The anchor module further includes: a frame carrying the front and rear anchor pads, the frame supporting the drilling module; and an actuator device to which the front and rear anchor pads are fastened, the actuator device being movable relative to the frame in a movement direction that extends transversely to the longitudinal direction; whereby the assembly constituted by the front anchor pad, the rear anchor pad, and the actuator device is movable in the movement direction relative to the frame and the drilling module.
