Excavator Antenna Storage Layout With Connected Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing and storing antenna devices on construction machines, such as hydraulic excavators, are complicated due to the need to disconnect and reconnect cables, which complicates the process of removing and attaching the devices for storage and protection.
Innovation Solution
A construction machine design featuring an antenna accommodation room within the vehicle body frame, equipped with an antenna retaining tool and cable protection tools, allows for the secure storage and reattachment of antenna devices while maintaining cable connection, simplifying the process and protecting the devices from damage and theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna device is removed from the vehicle body for storage, then the antenna device can be protected from damage and theft, but the work of removing and reconnecting cables becomes complicated
Solution Approach 1:
The antenna device is segmented from the vehicle body structure, allowing it to be removed and stored independently while maintaining cable connections through the housing cover opening/closing mechanism
Solution Approach 2:
The housing cover acts as an intermediary element that allows the antenna device to be stored within the vehicle body while maintaining cable connections, eliminating the need for repeated cable disconnection and reconnection
2Reliability
If the antenna device is stored in the cab or warehouse, then the antenna device can be protected from damage and theft, but the work of connecting cables to the antenna device becomes necessary
Solution Approach 1:
The storage function and cable connection function are merged into a single integrated system where the antenna device can be stored within the vehicle body while maintaining continuous cable connections through the housing cover mechanism
Solution Approach 2:
The cable connections are established in advance and maintained continuously, eliminating the need for repeated connection and disconnection operations during storage and retrieval

AI summary
An upper revolving structure 3 of a hydraulic excavator 1 includes a heat exchanger room 12 and a pump room 13 that respectively accommodate first and second antenna devices 24, 27 removed from first and second antenna attaching tools 25, 28 in a state where antenna-side cables 26A, 29A are connected to the first and second antenna devices 24, 27, and first and second antenna retaining tools 30, 33 that are arranged inside the heat exchanger room 12 and the pump room 13 to retain the first and second antenna devices 24, 27 removed from the first and second antenna attaching tools 25, 28. A housing cover 11 is configured to cover the heat exchanger room 12 and the pump room 13 in an openable or closable manner and include a left rear side door 16 and a right side door 19 that can be locked in a state where the heat exchanger room 12 and the pump room 13 are closed.
