Swing-Type Operation Machine Operator Station Mounting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swing-type operation machines face challenges in mounting an operator station with sufficient rigidity and strength on a swing table without increasing the table's size or utilizing a counter weight, due to limited space and variability in counter weight installation.
Innovation Solution
A swing-type operation machine design featuring a heat exchanger-mounting body with a double housing structure supporting a heat exchanger and the operator station, along with a support body and coupling plate that provides elastic mounts for the seat and equipment, eliminating the need for additional support legs and counter weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a pair of right and left legs is provided to support the operator station, then the mounting structure gains sufficient strength, but the installation space increases resulting in an increase in the outer circumferential edge of the swing table
Solution Approach 1:
The patent combines the support function with the heat exchanger mounting structure. The heat exchanger mounting body serves dual purposes: it mounts the heat exchanger for engine cooling and simultaneously supports the operator station. This merging eliminates the need for separate support legs, thereby maintaining mounting strength while avoiding an increase in the swing table's outer circumferential edge.
Solution Approach 2:
The heat exchanger mounting body is designed as a multi-functional component. It performs the heat dissipation function by mounting the heat exchanger, and simultaneously provides structural support for the operator station. This multi-functionality resolves the contradiction by eliminating the need for additional support structures that would increase the swing table size.
2Device complexity
If the counter weight is provided with support poles to mount the operator station, then the mounting structure is simplified, but this solution is not universally applicable as counter weights are not always provided or positioned appropriately
Solution Approach 1:
The heat exchanger mounting body serves itself by providing both its primary function (mounting the heat exchanger) and the additional function of supporting the operator station. This self-service approach creates a universal solution that does not depend on the presence or position of a counter weight, making it applicable across different machine configurations.
Solution Approach 2:
The mounting structure is segmented into independent functional components. The heat exchanger mounting body is a separate, self-contained structure that provides support functionality independent of the counter weight system. This segmentation allows the solution to be universally applied regardless of whether a counter weight is present or its position.

Function Achieved in This Case
This design allows for a simple, robust mounting of the operator station with enhanced strength and stability without enlarging the swing table, ensuring effective support and comfort for the operator while maintaining a compact profile.
Implementation Method 1
a floor portion mounted on a swing frame of the swing table via an elastic mount and a back-of-the-seat portion mounted on the coupling plate via an elastic mount

AI summary
To realize a mounting structure on the rear side of the seat of the operator station on which the seat and equipment for operation are installed in the swing table of a swing-type operation machine, the mounting structure being simple in construction yet imparted with a sufficiently large strength without increasing the size of the swing table or without utilizing the counter weight. The swing-type operation machine comprises an under carriage, a swing table mounted on the under carriage so as to freely swing thereon, an operator station mounted on the swing table and on which a seat and equipment for operation are installed, and a heat exchanger-mounting body supporting a heat exchanger for cooling the engine that is positioned at the back of the seat of the operator station and supporting the rear part of the seat of the operator station.
