Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manoeuvring members for soil drilling machines are costly and time-consuming to adapt to different drilling units, requiring manual intervention for coupling and releasing, which limits their field of use and efficiency.
Innovation Solution
A manoeuvring member with a hydraulically actuated blocking device and detection system that allows for remote operation of coupling pins, eliminating the need for manual intervention and enabling easy adaptation to various drilling units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual intervention is used for coupling and releasing pins, then operational control is achieved, but time consumption and labor costs increase
Solution Approach 1:
The patent replaces the manual mechanical operation system with a hydraulic actuation system. The blocking device is actuated hydraulically through a circuit that distributes fluid to multiple pins simultaneously, eliminating the need for manual intervention and significantly reducing coupling and releasing time while maintaining precise operational control
Solution Approach 2:
The patent implements a hydraulic actuation system where a hydraulic circuit with distributors actuates multiple blocking pins simultaneously. This hydraulic mechanism replaces manual operation, enabling rapid coupling and releasing of the manoeuvring member with the drilling assembly without requiring operator intervention at each pin location
2Ease of manufacture
If non-standardized coupling members are used for different manufacturers, then manufacturing flexibility is achieved, but adaptability and compatibility decrease
Solution Approach 1:
The patent designs the blocking device with universal features that enable compatibility across different manufacturers' drilling units. The standardized interface and modular hydraulic actuation system allow the same manoeuvring member to be adapted to various drilling assemblies, achieving both manufacturing efficiency and broad adaptability without requiring manufacturer-specific customizations
3Reliability
If multiple pins are used for coupling, then connection reliability is improved, but operational complexity increases
Solution Approach 1:
The patent merges the operation of multiple blocking pins into a single hydraulic control system. Instead of operating each pin independently, a unified hydraulic circuit with distributors actuates all pins simultaneously through fluid pressure, maintaining the reliability benefits of multiple pins while dramatically reducing operational complexity to a single control mechanism

AI summary
A maneuvering member for selectively attaching an actuating rotary member to a head portion of a drilling assembly. The maneuvering member includes a frame having an axial-symmetrical tubular portion internally delimited by a cylindrical mantle. The frame includes a first end that selectively interfaces with the actuating rotary member, and a second end provided with an alignment member for interfacing with a corresponding alignment member of the head portion of the drilling assembly. Hydraulically actuated blocking means is positioned at the second end and includes a pin that is actuated by a hydraulic fluid in a radially movable manner with respect to the frame at the second end. The pin is actuated between a back position in which the pin is arranged flush with the cylindrical mantle, and a forward position in which the pin projects inside the cylindrical mantel to selectively release/secure the head portion of the drilling assembly.
