Construction Machinery Guy Line Intermediate Support Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching intermediate support lines to guy lines in construction machines face difficulties due to the lack of sufficient workspace between the guy lines and the derricking member, making the process labor-intensive, especially during assembly and disassembly of construction machines.
Innovation Solution
An intermediate support holder is designed to facilitate the attachment of intermediate support lines to guy lines without the need for additional workspace, utilizing a bracket system that includes guy line attachment portions, intermediate support attachment portions, and a transverse member to secure and align the lines, allowing for easy attachment even when the jib is laid down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the intermediate support line is attached to the guy line in a conventional manner requiring workspace between the guy line and derricking member, then the attachment can be performed with simple equipment, but the attachment work becomes difficult and labor-intensive when the derricking member is laid down on the ground
Solution Approach 1:
The patent introduces an intermediate support holder as a mediator device that connects the guy line and the intermediate support line. This holder includes a guy line attachment portion that attaches to the guy line and an intermediate support line attachment portion that attaches to the intermediate support line, enabling attachment work even when workspace is limited
Solution Approach 2:
The intermediate support holder utilizes the radial direction of the guy line as an additional dimension for attachment. By attaching the intermediate support line to the guy line in the radial direction rather than requiring lateral workspace, the device enables attachment in confined spaces
2Strength
If a pair of right and left intermediate support lines are provided as is conventional, then the structural support is adequate, but the attachment work must be performed on both sides which doubles the labor required
Solution Approach 1:
The patent merges the attachment operations for right and left intermediate support lines by providing a single intermediate support holder that can attach both lines. The holder includes right and left intermediate support line attachment portions that simultaneously secure both intermediate support lines, reducing the number of separate attachment operations

AI summary
The intermediate support holder (60) includes right and left guy line retaining units 61, right and left intermediate support line retaining units (63), and a connecting unit (80). The intermediate portions (40m) of the guy lines 40 can be attached to the guy line retaining units (61). The intermediate support line retaining units (63) are disposed so as to be aligned in the right-left direction Y with respect to the guy line retaining units (61), and base end portions of the intermediate support lines (50) can be attached to the intermediate support line retaining units (63). The connecting unit (80) couples and fixes the pair of right and left guy line retaining units 61 and the pair of right and left intermediate support line retaining units (63) to each other.
