Adjustable Split Elevator Guide Rail Bracket Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing guide rail installation process for elevator systems is cumbersome and requires high operational effort due to the large size and weight of guide rails, making precise alignment challenging and labor-intensive.
Innovation Solution
A split-type elevator guide rail installation bracket with adjustable components, including a guide rail bracket and a hoistway bracket, along with positioning and adjustment tooling, allows for precise positioning and alignment by adjusting the relative position between the guide rail and hoistway brackets, reducing the need for extensive manual adjustment of the heavy guide rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guide rails are adjusted for precise alignment, then manufacturing precision is improved, but device complexity increases due to the need for extensive adjustment mechanisms
Solution Approach 1:
The installation bracket is divided into multiple adjustable components including a bracket body, adjustable support legs with threaded rods, and positioning plates. Each segment can be independently adjusted to achieve precise alignment without requiring complex overall adjustment mechanisms.
Solution Approach 2:
The bracket incorporates dynamic adjustment capabilities through threaded rods that allow the support legs to be extended or retracted. This enables the bracket to adapt its position and orientation during installation to achieve precise guide rail alignment.
2Manufacturing precision
If guide rails are manually adjusted for alignment, then manufacturing precision is improved, but loss of time increases due to labor-intensive adjustment processes
Solution Approach 1:
The bracket is pre-assembled with adjustable support legs and positioning plates in specific configurations before installation. This preliminary preparation reduces on-site adjustment time and enables faster achievement of precise alignment during installation.
Solution Approach 2:
The manual adjustment process is supplemented by mechanical adjustment mechanisms built into the bracket, such as threaded rods and locking nuts, which allow for more efficient and precise positioning compared to purely manual methods.
3Manufacturing precision
If heavy guide rails are adjusted for alignment, then manufacturing precision is improved, but force requirements increase making the process more difficult
Solution Approach 1:
The adjustable bracket serves as an intermediary between the heavy guide rails and the installation structure. It provides a stable, adjustable platform that supports the guide rails during alignment, reducing the force needed to position and align them precisely.
Solution Approach 2:
The bracket's adjustable support legs and positioning plates are designed to self-adjust under the weight of the guide rails, allowing the system to find its own equilibrium position with minimal external force applied during the alignment process.
