Elevator Traction Belt Cleaning Assembly With Adaptive Brush Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator traction belt cleaning devices face challenges in maintaining a consistent cleaning distance due to varying belt positions, leading to poor cleaning efficacy, noise, and reduced brush lifespan.
Innovation Solution
A slidable cleaning assembly with adjustable sand removing members and guide components that maintain a consistent gap with the traction belt, ensuring effective sand removal while reducing noise and extending the service life of cleaning components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed brush is used to scrape off sand particles on the traction belt, then the cleaning device structure is simple, but the cleaning effect becomes poor when the belt position varies
Solution Approach 1:
The cleaning brush is designed to be movable rather than fixed, allowing it to dynamically adjust its position relative to the traction belt. The brush can slide along the belt's movement direction and automatically positions itself to maintain optimal contact, ensuring reliable cleaning performance even when belt position varies during operation.
2Reliability
If the cleaning brush is positioned closer to the traction belt to improve cleaning effect, then cleaning performance improves, but noise increases and brush wear accelerates
Solution Approach 1:
The cleaning brush is designed with movable mounting that allows automatic adjustment of the contact pressure and distance from the traction belt. During operation, the brush dynamically positions itself to maintain optimal cleaning contact without excessive pressure, thereby reducing noise and wear while preserving cleaning effectiveness.
3Object-generated harmful factors
If the cleaning brush is positioned farther from the traction belt to reduce noise and wear, then harmful factors decrease, but cleaning effect deteriorates
Solution Approach 1:
The cleaning brush employs a dynamic mounting mechanism that enables automatic adjustment during operation. The brush can move closer to the traction belt when needed for effective cleaning and maintain appropriate distance when not in contact, thus achieving both good cleaning effect and reduced noise and wear through adaptive positioning.
4Device complexity
If a fixed cleaning device is used, then the device structure is simple, but the service life of the brush is reduced due to inconsistent contact distance
Solution Approach 1:
The cleaning brush is designed with a dynamic mounting system that allows it to automatically adjust its position and maintain consistent contact distance with the traction belt during operation. This dynamic adjustment prevents excessive wear from inconsistent contact, thereby extending brush service life while keeping the overall device structure relatively simple.
