Well Pipe Removal Spool with Foldable Crane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing well pipe removal systems require extensive space for laying out pipes, leading to damage, contamination, and clogging issues, and are limited by the height of mobile cranes and the need for multiple personnel and power sources.
Innovation Solution
A well pipe pulling and storage device comprising a pipe spool, wire spool, hydraulic power supply, and a foldable crane mounted on a skid steer vehicle, allowing for simultaneous coiling and uncoiling of pipes and wires with controlled speed and direction, eliminating the need for extensive space and reducing manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pipe is manually pulled or dragged across the ground, then the pipe can be removed from the well, but the pipe suffers damage and contamination
Solution Approach 1:
The patent introduces a spool as an intermediary device between the pipe and the ground. The pipe is coiled around the spool which is mounted on a vehicle, eliminating direct contact between the pipe and ground surface. This mediator prevents contamination from mud, grass, mulch, pesticides, herbicides, animal feces, mold and other harmful substances while maintaining pipe integrity during removal operations
Solution Approach 2:
The patent replaces the traditional manual dragging or ground-laying mechanical system with a vehicle-mounted spool system. The spool rotates to pay out or wind in the pipe as the vehicle moves, substituting the harmful mechanical action of dragging across ground with a controlled rotational mechanism that keeps the pipe elevated and protected
2Object-affected harmful factors
If a mobile crane is used to hoist the pipe, then the pipe can be pulled upward without laying on ground, but the crane height is limited and requires open spaces
Solution Approach 1:
The patent creates a universal pipe removal system that can operate in multiple environments including wooded areas, developed residential or commercial areas, and locations with overhanging structures or foliage. The vehicle-mounted spool system combines the ground-contact avoidance benefit of cranes with the mobility and adaptability of ground vehicles, making it universally applicable where traditional cranes cannot operate
Solution Approach 2:
The patent introduces dynamic adaptability through a vehicle-mounted system that can move to different positions and adjust to various terrain conditions. Unlike fixed or height-limited cranes, the vehicle can navigate to optimal positions and the spool system can accommodate different pipe lengths and removal scenarios, providing dynamic adaptability to changing operational environments
3Ease of operation
If the pipe is extended to full length on the ground, then the pipe can be accessed for pump removal, but significant space is required and ground surface is disturbed
Solution Approach 1:
The patent transitions the pipe storage from a two-dimensional ground-laid configuration to a three-dimensional coiled configuration around the spool. This vertical stacking of pipe length around the spool circumference eliminates the need for extensive horizontal space while maintaining full pipe accessibility for pump removal operations
Solution Approach 2:
The patent implements nesting by coiling the pipe around the spool, with each section of pipe nested within the spatial envelope of the spool structure. This nested configuration compactly stores the full pipe length in a confined space while keeping the pipe accessible and organized for maintenance operations
