Elevator Installation Guide Devices for Shaft Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing elevators in buildings during construction require precise manual alignment of heavy elevator units, leading to a risk of damage and accidents, and are time-consuming and costly due to the need for manual fitting of guide rails and guide shoes.
Innovation Solution
A method for installing elevator systems that uses pre-assembled elevator units and guide devices cooperating with stationarily fixed alignment elements to align and fit guide shoes with car guide rails, reducing manual alignment risks and costs by using guide devices that align the elevator units before lowering, allowing for easier and safer fitting of guide shoes and car guide rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual alignment of heavy elevator units is performed during lowering, then precise positioning can be achieved, but the risk of damage and accidents increases and installation time is extended
Solution Approach 1:
Alignment elements are introduced as intermediary components between the elevator unit and the guide rails. These alignment elements automatically guide the elevator unit into the correct position during lowering, eliminating the need for manual alignment while preventing damage and accidents.
Solution Approach 2:
The alignment elements are designed to automatically perform the alignment function without requiring manual intervention. The elevator unit self-aligns with the guide rails through the alignment elements, reducing both the risk of damage and the time required for positioning.
2Manufacturing precision
If manual alignment of heavy elevator units is performed during lowering, then positioning can be controlled, but installation time and costs increase
Solution Approach 1:
Alignment elements serve as mediators that automatically guide the elevator unit into the correct position during lowering, eliminating the time-consuming manual alignment process while maintaining positioning precision.
Solution Approach 2:
The alignment elements enable the elevator unit to self-align with the guide rails without requiring manual intervention, significantly reducing installation time while maintaining the necessary positioning accuracy.
3Manufacturing precision
If guide rails and guide shoes are fitted manually, then precise engagement can be achieved, but the risk of damage to components increases
Solution Approach 1:
Alignment elements act as protective intermediaries during the fitting process. They guide the guide rails and guide shoes into correct engagement without requiring manual force, thereby preventing damage to the components while achieving precise engagement.
Solution Approach 2:
The alignment elements are positioned beforehand to prevent direct contact and potential damage between the guide rails and guide shoes during the fitting process, cushioning against impact and misalignment forces.

AI summary
A method for installing an elevator system in an elevator shaft of a building in its construction phase uses a machine platform displaceable in the shaft along car guide rails and having a drive machine for moving a suspended elevator car to adapt a usable lifting height of the elevator car to an increasing height of the building by lifting the machine platform to a higher level. The method includes lowering a pre-assembled elevator unit into the shaft by a lifting device, using guide devices that are either mounted on the elevator unit and cooperate with stationarily fixed alignment elements in the shaft, or are fixed in the shaft and cooperate with alignment elements on the elevator unit, to align the unit in a position suitable for fitting guide shoes on the elevator unit and the car guide rails into one another.
