Top Drive Load Frame Module for Rapid Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current well drilling machines require extensive and time-consuming maintenance due to complex mechanical components, leading to prolonged downtime and increased repair times, especially when drilling deeper wells.
Innovation Solution
The introduction of a load frame module that serves as a maintenance-free structural element, relieving the drive shaft and power transmission, and allowing for quick release coupling of main components, enabling rapid disassembly and assembly of the drilling machine into modular units for efficient maintenance and repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex mechanical components are used in prior art drilling machines, then the drilling function is achieved, but the repair time increases and maintenance becomes time-consuming
Solution Approach 1:
The drilling machine is divided into modular components (drive shaft, power transmission, load frame, torque arresting device) that can be independently maintained and replaced. This segmentation allows rapid disassembly and repair without affecting the entire system, directly reducing repair time while maintaining drilling functionality.
Solution Approach 2:
The patent introduces quick release coupling means that enable dynamic reconfiguration of the modular components. This allows the system to transition from a static, fixed mechanical assembly to a dynamic, easily reassembled structure, significantly reducing maintenance time and downtime.
2Reliability
If complex mechanical components are used in prior art drilling machines, then the drilling function is achieved, but the maintenance interval decreases
Solution Approach 1:
The modular design with quick release couplings enables the drilling machine to be easily serviced and reconfigured by the maintenance team without requiring complex disassembly procedures. This self-service capability allows for more frequent maintenance intervals while maintaining reliable drilling function, as components can be rapidly replaced or serviced as needed.
3Loss of time
If modular components with quick release coupling are used, then the repair time is reduced, but the device complexity increases
Solution Approach 1:
While segmentation increases the number of components, it organizes them into functional modules that are easier to manage and maintain. The standardized interfaces and quick release couplings simplify the overall system architecture despite the increased modularity, making maintenance faster and more predictable.

AI summary
A well drilling apparatus (10′) (top drive) designed to be suspended from a travelling block (6′) in a drawworks and laterally supported by a dolly (9′) running together with the well drilling apparatus along tracks or rails fixed to a derrick. The drilling apparatus (10′) comprises at least one driving motor (5′), one power transmission (4′) powered by the at least one driving motor (5′), a drive shaft (70) driven from the power transmission (4′) and designed to be connected to a drill string, load transferring means, and a torque arresting device (3′) fixed to and depending from the power transmission (4′). The load transferring means is in the form of a load frame module (1′) that relieves the drive shaft (70) and the power transmission (4′) at the same time as the load frame module (1′) forms a central component module that the other main components of the well drilling apparatus are releasable connected to.
