Tower Frame Pumping Unit Without Guiding Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tower frame pumping units face challenges in providing sufficient space for drilling and extending the duration of steel wires, as they require either time-consuming and energy-intensive movement of the tower frame or use of small guiding wheels that lead to rapid wire damage due to bending fatigue.
Innovation Solution
A tower frame transmitting pumping unit without guiding wheels, featuring a large-diameter rope wheel and a movable operation platform, uses a platform moving device with sliding tracks and jackscrews to create a safe and simple method for giving space to drill, while the rope wheel's increased diameter and optimized weight distribution enhance steel wire durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a guiding wheel is provided to extend the distance between the tower frame and well mouth, then drilling space is improved, but the steel wire duration deteriorates due to small bending diameter
Solution Approach 1:
The invention removes the guiding wheel component entirely from the system. Instead of using a guiding wheel to extend drilling space, the tower frame itself is made movable through a moving device, allowing the entire frame to be repositioned away from the well mouth during drilling operations, thereby eliminating the bending fatigue issue caused by guiding wheels
Solution Approach 2:
The tower frame is transformed from a static structure to a dynamic one by introducing a moving device that enables the frame to move horizontally away from the well mouth. This dynamic capability allows the system to adapt to different operational phases: positioned during pumping and repositioned during drilling, eliminating the need for guiding wheels
2Volume of moving object
If the whole tower frame is moved to give space for drilling, then drilling space is improved, but energy consumption and time increase
Solution Approach 1:
The system is divided into movable and stationary components. The operation platform with drilling equipment can be moved independently relative to the tower frame through the moving device, rather than moving the entire heavy tower frame structure. This segmentation reduces the mass that needs to be moved and consequently reduces energy consumption
Solution Approach 2:
Instead of moving the entire tower frame structure, only the necessary components (operation platform with drilling equipment) are moved to the extent required to provide drilling space. This partial action approach minimizes energy consumption while achieving the drilling space requirement
3Ease of manufacture
If a small diameter guiding wheel is used, then costs and stability are improved, but steel wire duration deteriorates due to bending fatigue
Solution Approach 1:
The guiding wheel component is completely removed from the system. The invention replaces the guiding wheel function with a different mechanism (movable tower frame) that eliminates the source of steel wire damage, thereby solving the contradiction between cost-effective simple design and steel wire durability
Solution Approach 2:
The invention converts the potential harm of steel wire bending fatigue into a benefit by redesigning the system to eliminate bending entirely. The movable tower frame approach allows steel wires to remain straight during both pumping and drilling operations, transforming what would have been a harmful bending situation into a beneficial straight-line configuration
