Telescopic Connection Component for Aerial Work Platform Horizontal Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerial work platforms with parallelogram construction have limited horizontal reach and flexibility, restricting their working area and safety due to the length of connection arms.
Innovation Solution
A telescopic connection component with an outer arm, inner arm, and forearm telescopic cylinder, along with levelling and luffing cylinders, allows for increased horizontal reach and stability by enabling the inner arm to slide out of the outer arm, and providing a triangle luffing mechanism and additional levelling systems for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a parallelogram construction is used for the forearm connecting the operation platform and main arm, then the structure is simple and easy to manufacture, but the horizontal reach is seriously restricted by the length of the connection arm
Solution Approach 1:
The patent applies nesting by placing the inner arm inside the outer arm, allowing the inner arm to slide telescopically within the outer arm. This nested configuration enables the connection component to achieve greater horizontal reach without proportionally increasing overall structural complexity, as the arms are contained within each other's volume when retracted.
Solution Approach 2:
The patent transforms the static parallelogram connection into a dynamic telescopic structure where the inner arm can slide in and out of the outer arm. This dynamic mechanism allows the horizontal reach to be variable rather than fixed, enabling extended working range while maintaining a compact stored configuration.
2Adaptability or versatility
If a parallelogram construction is used for the forearm, then the manufacturing is easier, but the flexibility in the working area is reduced
Solution Approach 1:
The nested telescopic arm structure provides flexibility by allowing the inner arm to extend and retract within the outer arm, enabling the platform to reach various positions and angles. This nested design maintains adaptability while keeping the structure relatively simple compared to multiple separate linkage mechanisms.
Solution Approach 2:
The dynamic telescopic mechanism allows the connection component to adapt to different working positions and angles by varying the extension of the inner arm, providing greater flexibility in the working area compared to a fixed-length parallelogram construction.
3Length of moving object
If the connection arm length is increased to improve horizontal reach, then the working area is expanded, but the structural strength and stability are reduced
Solution Approach 1:
The nested telescopic structure allows the connection component to achieve extended horizontal reach when needed, while maintaining compact, structurally strong configuration during storage or transport. The outer arm provides structural support, and the inner arm can extend only when required for working, preserving overall structural integrity.
Solution Approach 2:
The dynamic telescopic mechanism enables the structure to adapt its length based on operational requirements, extending to achieve greater horizontal reach during work operations while retracting to maintain structural strength and stability during non-operational phases.
4Area of stationary object
If the connection arm length is increased to expand working area, then the horizontal reach is improved, but the structural stability is reduced
Solution Approach 1:
The nested telescopic arms provide structural stability through the outer arm's rigid structure that contains and supports the inner arm. When the inner arm extends to expand working area, the outer arm maintains overall structural stability, and the nested configuration prevents lateral instability that would occur with a simple long arm extension.

AI summary
The present invention relates to field of engineering mechanics and more particularly, relates to an engineering work vehicle, and most particularly, relates to a telescopic connection component (5) and aerial work platform (3). A telescopic connection component for telescopically connecting a telescopic transmission component (2) and an operation platform of an aerial work platform together includes: an outer arm (51), an inner arm (52) slidably disposed inside the outer arm and capable of being moved out from one end of the outer arm, and a forearm telescopic cylinder (53) disposed between the outer arm and inner arm. The telescopic connection component has longer horizontal reach so that the operation platform is capable of moving to a further region in a horizontal direction, thus increasing working range of the aerial work platform. In addition, the telescopic connection component has higher structural strength and stability and accordingly, it also improves safety of the aerial work platform.
