Anti-Shaking Lifting Apparatus for Highly-Mounted Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting apparatuses for highly-mounted devices, such as lights and CCTV cameras, are prone to shaking and falling due to external forces like wind, leading to performance deterioration and safety risks, especially when installed at heights requiring complex and time-consuming maintenance operations.
Innovation Solution
A lifting apparatus with a drum and driving motor system, featuring a fixing instrument with a screw bolt and second driving motor to securely fasten the lifting body to a stopper, preventing shaking and ensuring stable installation, and including guide rolls and contact points for reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lifting body is caught by a stopper to keep its fixed state, then the lifting body can be positioned at the desired height, but the lifting body is vulnerable to shaking by external forces such as wind and vibration
Solution Approach 1:
The fixing instrument applies a preliminary fixing force to the lifting body through the fixing rod and screw mechanism, creating a stabilizing effect before external forces like wind or vibration can cause shaking. This preliminary anti-action counteracts the potential instability caused by the stopper-only fixation method.
2Device complexity
If a simple stopper structure is used to fix the lifting body, then the device complexity is reduced, but the lifting body may be easily shaken by external forces
Solution Approach 1:
The fixing function is divided into two independent components: the stopper for basic positioning and the fixing instrument with screw mechanism for additional stabilization. This segmentation allows each component to perform its specific function effectively, with the stopper providing position limitation and the fixing instrument providing anti-shaking capability.
3Ease of manufacture
If the lifting body is caught by the stopper, then the installation is simple, but the highly-mounted device may fall under strong wind conditions
Solution Approach 1:
The fixing instrument with screw mechanism provides beforehand cushioning by applying continuous fixing force to the lifting body, preparing it to resist strong wind conditions before they occur. This prior stabilization prevents the device from falling under extreme weather conditions.

Function Achieved in This Case
The apparatus effectively stabilizes the lifting body, reducing the risk of device failure and improving contact reliability, allowing for safer and more efficient maintenance of highly-mounted devices by preventing shaking and potential falls.
Implementation Method 1
a drum for winding a wire rope and a first driving motor for giving a rotating force to the drum
Implementation Method 2
a fixing instrument configured to apply a force to any one of the upper contact point and the lifting body... so that the lifting body comes into close contact with the stopper

AI summary
A lifting apparatus for a highly-mounted device includes a main body installed at a predetermined height so that a drum for winding a wire rope and a first driving motor for giving a rotating force to the drum are installed thereto; a lifting body suspended from the wire rope and having a device coupling portion provided at a lower end thereof; an accommodation structure located at a lower portion of the main body and having an open lower portion so as to be coupled with the lifting body; a stopper installed at the accommodation structure and caught by a suspending protrusion provided to the lifting body to give an anti-falling function for the lifting body; and an upper contact point and a lower contact point respectively installed at the main body and the lifting body to make contact with each other when the lifting body is moved up.
