Integrated Conduit Injector for Low-Height Well Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous conduit work equipment is too tall due to the separate guiding gooseneck and injector head configuration, making it unsuitable for environments with limited space height, such as coal mines with heights less than 3 meters.
Innovation Solution
A continuous conduit apparatus with an integrated guiding and injecting mechanism, featuring a straightening apparatus and sprocket and chain clamping assemblies that form an arc-shaped conduit guide channel, allowing the conduit to be pulled downwards or upwards, and a roller straightening apparatus to ensure vertical insertion, reducing device height and minimizing abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate guiding gooseneck and injector head configuration is used, then the guiding function and injecting function are achieved, but the device height becomes too tall for limited space environments
Solution Approach 1:
The patent combines the guiding gooseneck and injector head into an integrated guiding-injecting mechanism. The guiding channel and injecting components are merged into a single structure where the conduit is guided through an arc-shaped path and injected directly, eliminating the need for a separate high gooseneck structure while maintaining both guiding and injecting functions.
2Length of stationary object
If the inlet and outlet of the conduit guide channel are not in a straight line, then the device height is reduced, but the conduit may experience abrasion during insertion
Solution Approach 1:
The patent employs an arc-shaped guiding channel with a specific radius of curvature that matches the conduit's bending capability. This curved path allows the conduit to follow a smooth arc from the inlet to the outlet without sharp angles or kinks, preventing abrasion while accommodating the non-straight line configuration that reduces device height.
3Object-affected harmful factors
If a straightening apparatus is added to ensure vertical conduit insertion, then conduit abrasion is reduced, but the device complexity increases
Solution Approach 1:
The straightening function is merged into the guiding channel structure itself. The arc-shaped channel is designed with specific geometric parameters that inherently straighten the conduit as it passes through, eliminating the need for a separate straightening apparatus. The guiding channel simultaneously performs guiding, straightening, and abrasion prevention functions.

AI summary
Disclosed is a continuous conduit apparatus based on guiding and injecting integrated mechanism, which comprises a straightening apparatus and a pair of sprocket and chain clamping assemblies. The pair of sprocket and chain clamping assemblies are configured to clamp the conduit and pull the conduit to go downwards a well or upwards a lifting direction. Between the pair of sprocket and chain clamping assemblies, a conduit guide channel applied for the conduit to passing through is formed. An inlet and an outlet of the conduit guide channel are not situated in a straight line, and the straightening apparatus are configured to straighten the conduit. Each of the two sprocket and chain clamping assemblies comprises a sprocket set, a chain, a plurality of clamping blocks mounted on the chain, and a pushing plate configured to press the clamping blocks.
