Split Sub-Basement Drill Rig Lifting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable land drill rigs require complex and high-tension cabling systems to raise the rig floor during assembly, which is cumbersome and inefficient.
Innovation Solution
A sub-basement assembly using a hydraulic cylinder to raise the drill rig floor in multiple stages, with a linkage structure that locks in place to support the rig floor, eliminating the need for high-tension wire ropes and allowing for a more compact and easily controlled lifting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire rope system with pulleys is used to raise the rig floor, then the rig can be assembled, but the system becomes complex and requires high-tension cabling
Solution Approach 1:
The patent removes the complex wire rope and pulley system from the rig assembly process. Instead, it extracts only the essential lifting function and implements it through a simpler hydraulic cylinder mechanism that directly raises the rig floor without requiring high-tension cabling or multiple pulleys.
Solution Approach 2:
The patent replaces the mechanical wire rope and pulley system with a hydraulic system. The hydraulic cylinder uses fluid pressure to generate lifting force, substituting the mechanical advantage of pulleys with hydraulic force multiplication, thereby eliminating the need for complex cabling systems.
2Device complexity
If a hydraulic cylinder is used to raise the rig floor, then the lifting system becomes simpler and more controllable, but the structural height increases
Solution Approach 1:
The patent designs the sub-basement structure with nested components where the hydraulic cylinder and linkage mechanism are integrated within the existing structural space. The linkage structure folds or retracts into the sub-basement when not in use, allowing the system to achieve full lifting capability while maintaining a compact overall height suitable for transport.
Solution Approach 2:
The patent employs a dynamic linkage structure that changes configuration during operation. The linkage can extend and lock at various positions during the lifting process, allowing the rig floor to be raised to the required height while the sub-basement maintains a compact form factor for transport when the linkage is retracted.

AI summary
A substructure of a drill rig includes, among other things, a base and an intermediate section that is adapted to be raised above the base, wherein the intermediate section is further adapted to be laterally moved in a first lateral direction relative to the base and maintained substantially parallel to the base during the raising of the intermediate section above the base. The substructure further includes a rig floor section that is adapted to be raised above the intermediate section, wherein the rig floor section is further adapted to be laterally moved in a second lateral direction relative to the base and maintained substantially parallel to the base during the raising of the rig floor section above the intermediate section, the second lateral direction being opposite to the first lateral direction.
