Bundle Guiding Device for Compressor Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-sized vertical division type compressors, the narrow clearance between the casing and the bundle requires high skill and prolonged working hours to insert the bundle without contact, as even with angular adjustments, positional shifts can cause contact during insertion.
Innovation Solution
An assembly method and bundle guiding device using internal and external travel devices with position detection and adjustment mechanisms to precisely align and insert the bundle, preventing contact by adjusting the bundle's height, horizontal position, and angle based on real-time measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bundle is inserted into the casing with a clearance of less than 1 mm, then the compressor achieves compact design, but the worker requires high skill and prolonged working hours to prevent contact between the bundle and casing
Solution Approach 1:
The patent introduces a bundle guiding device as an intermediary tool during the insertion process. This guiding device includes a carriage that moves along the inner peripheral surface of the casing and a bundle support that holds the bundle, enabling precise positioning and alignment without requiring the worker to manually skillfully manipulate the bundle insertion, thus resolving the contradiction between small clearance and ease of operation
Solution Approach 2:
The patent applies preliminary action by pre-positioning the bundle and adjusting its position before insertion. The bundle support and carriage system allow the worker to pre-align the bundle with the casing axis and adjust its position, ensuring proper alignment is achieved before the actual insertion occurs, thereby reducing the skill level required during the insertion process itself
2Manufacturing precision
If the bundle is inserted manually with high precision alignment, then contact between bundle and casing is prevented, but the working hours for insertion are prolonged
Solution Approach 1:
The bundle guiding device serves as an intermediary that automates the precise alignment process. The carriage moving along the casing inner peripheral surface and the bundle support system provide mechanical guidance that ensures precise alignment without requiring the worker to spend extensive time on manual adjustment, thus reducing both the skill requirement and insertion time
Solution Approach 2:
The guiding device enables self-service alignment where the system itself provides the precise positioning and alignment functions. The carriage automatically guides the bundle along the correct path, and the bundle support maintains proper alignment, allowing the insertion process to be completed quickly without requiring the worker to perform complex manual alignment operations

AI summary
This compressor assembly method involves: an arrangement step in which a bundle (2) is arranged such that an external travel device (31) can travel on a base surface (25) and an internal travel device can travel on the inner peripheral surface (12) of a casing (3); a vertical position adjustment step in which, while measuring the relative positions in the vertical direction of the inner peripheral surface (12) of the casing (3) and the outer peripheral surface (13) of the bundle (2) at the opening (15) of the casing, the height position of the bundle (2) supported by the outside travel device (31) is adjusted on the basis of the measured relative positions in the vertical direction; and an insertion step in which the bundle (2) is inserted into the casing (3) while the vertical position adjustment step is performed.
