Stabilizer Device With Telescopic Beam For Operating Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilizer devices for self-propelled operating machines, such as those used in the building and agriculture industries, have a limited transverse distance, which restricts the machine's stability and maximum load capacity, especially when the lifter arm and load are oriented crosswise, leading to reduced operational characteristics and increased costs.
Innovation Solution
The proposed stabilizer device features interconnected modules with linear and compass elongation means, operated by hydraulic jacks, allowing the resting feet to adjust from a retracted position to an extended position, thereby increasing the resting base width to be at least equal to its length, enhancing stability and load capacity while maintaining mobility within maximum size limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the transverse distance between stabilizer devices is increased to improve stability and load capacity, then the machine's resting base width increases, but the machine exceeds maximum size limits during transport
Solution Approach 1:
The stabilizer device employs a telescopic beam that can dynamically change its transverse dimension. During operation, the beam extends to maximize the resting base width for stability. During transport, the beam retracts to minimize the transverse dimension and comply with size limits. This dynamic adjustment resolves the contradiction between needing large transverse dimension for stability and small transverse dimension for transport.
Solution Approach 2:
The telescopic beam structure implements a nesting principle where the extendable sections are housed within the main beam structure. When retracted, the stabilizer device fits within maximum size limits. When extended, it provides the necessary transverse distance for stability without permanently increasing the machine's footprint.
2Strength
If the transverse distance between stabilizer devices is increased to improve stability, then the maximum load capacity increases, but the device complexity increases
Solution Approach 1:
The stabilizer device is segmented into modular components: a main beam, extendable telescopic sections, and resting feet. Each segment serves a specific function and can be independently controlled. This segmentation allows the device to achieve large transverse distance when needed while keeping the retracted profile compact, resolving the contradiction between load capacity and device complexity.
Solution Approach 2:
The patent employs hydraulic cylinders to actuate the telescopic beam and resting feet. This hydraulic system provides powerful, controlled extension and retraction movements with relatively simple actuation mechanisms. The hydraulic principle enables the complex motion required for large load capacity without proportionally increasing device complexity.
3Reliability
If the stabilizer device is designed to provide exact horizontal arrangement, then the operational safety improves, but the ease of operation decreases
Solution Approach 1:
The stabilizer device incorporates self-leveling functionality through sensors and automated control systems. The device automatically adjusts its position and orientation to achieve exact horizontal arrangement without requiring manual intervention or complex operator actions. This self-service capability improves operational safety while maintaining ease of operation.
Solution Approach 2:
The patent implements feedback mechanisms including sensors that monitor the horizontal arrangement and stability of the machine. This feedback information is used by the control system to automatically adjust the stabilizer device position, ensuring exact horizontal arrangement for safety while eliminating the need for complex manual operations.

AI summary
A first front pair (6A) and a second rear pair (6P) of stabilizer devices are associated to the frame (3) of an operating machine (M), to define, in operative position, a resting base, whose length (X) is equal to the longitudinal distance between the same pairs (6A, 6P) and whose width (Y) is equal to the transversal distance between the resting feet of each of the latter. Each of the above mentioned stabilizer devices (161, 162, 261, 262, 361, 362) includes at least a first and a second module (10, 11 ), interconnected with each other, one of which is provided with linear elongation means (12) and the other is provided with compass elongation means (13), with said linear elongation means (12) and compass elongation means (13) being aimed at being operated in phase relation to define a retracted inactive position (R), in which the corresponding resting foot (19, 25) is raised from the ground and the bulk of said stabilizer device (161, 162, 261, 262, 361, 362) is within the above mentioned machine (M) maximum size limits, and a withdrawn operation position (L), in which said resting foot (19, 25) contacts the ground, at a predetermined distance from the longitudinal midline, such that in this resting base the width (Y) distance is at least near to that of the relative length (X).
