Shaft Mounting Frame With Retractable Support for More Working Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting frames for shafts, such as elevator shafts, restrict the working region when fixed due to their design, which results in limited space for work operations.
Innovation Solution
A mounting frame design where the support component can be partially movable relative to the main frame during displacement and the secondary fixing component's contact part can assume different positions, allowing minimal spacing from the shaft wall when fixed, thus maximizing the working region.

1Area of stationary object
If the mounting frame is designed with fixed support components and immovable fixing components, then the structure is simple and reliable, but the working region is restricted when fixed in the shaft
Solution Approach 1:
The support component is designed to be movable relative to the main frame in the fixing direction, allowing it to transition between a displacement position (protruding outward for easy movement) and a fixing position (retracted for minimal space occupation). This dynamic configuration enables the mounting frame to maximize working region when fixed while maintaining structural simplicity during displacement.
Solution Approach 2:
The mounting frame is divided into distinct functional segments: the main frame, the movable support component, and the fixing components. The support component can be independently positioned relative to the main frame, allowing the working region to be optimized when fixed without complicating the overall structure during displacement operations.
2Ease of operation
If the support component protrudes outward during displacement, then easy displacement is achieved, but large spacing from shaft wall results when fixed
Solution Approach 1:
The support component is designed with movable capability relative to the main frame, allowing it to dynamically adjust its position. During displacement, it protrudes outward to facilitate easy movement and contact with the shaft wall. During fixing, it retracts to minimize the distance from the shaft wall, thereby maximizing the working region.
Solution Approach 2:
The support component is preliminarily positioned in a protruding state during displacement to ensure easy movement and proper contact with the shaft wall. Before fixing occurs, the component is then retracted to achieve minimal spacing from the shaft wall, preparing the system for the next phase of operation.

AI summary
A mounting frame for displacing and fixing in a shaft includes a support component for support against a first shaft wall during displacement in the shaft and is arranged on a main frame so as to be at least partially movable in a fixing direction relative to the main frame. The support component can assume a fixing position and a displacement position, with no part of a support surface being spaced further outward in the fixing direction, i.e. toward the first shaft wall, from the main frame in the fixing position than a fixing surface of a primary fixing component that is used to fix the mounting frame in the shaft, and the support surface is spaced further outward from the main frame in the fixing direction in the displacement position than the fixing surface.
