Roller Crusher Handling Apparatus for Roller Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for dismounting and mounting rollers from roller crushers are complex, time-consuming, and costly due to the need to remove and reassemble the entire shaft, crushing shell, and bearing housings, which are heavy and require special care.
Innovation Solution
A handling apparatus with a movable base, pivotally attached carrier, and extendable pivoting devices that allow for safe and simple mounting and dismounting of rollers, enabling automatic and efficient handling, including transport for replacement or conditioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire assembly (shaft, crushing shell, end bearings, and bearing housings) is removed for roller replacement, then the roller can be adequately reconditioned or replaced, but the operation becomes complex, time-consuming, and expensive
Solution Approach 1:
The invention separates the roller handling function from the entire crusher assembly. A dedicated handling apparatus with modular components (base, carrier, pivoting devices) is introduced to isolate and manipulate only the roller, allowing replacement without removing the shaft, crushing shell, or bearing housings.
Solution Approach 2:
The handling apparatus acts as an intermediary device between the roller and the crusher assembly. It provides a mechanical interface that engages the roller and bearing housing, enabling controlled removal and installation without direct manual handling of the heavy components.
2Ease of repair
If the entire assembly is removed and transported for roller reconditioning, then proper maintenance can be performed, but the operation requires special care and becomes expensive
Solution Approach 1:
The invention extracts only the necessary components (roller and bearing housing) from the crusher assembly using the handling apparatus, leaving the shaft and crushing shell in place. This selective extraction eliminates the need to transport the entire heavy assembly for maintenance.
Solution Approach 2:
The handling apparatus is positioned and prepared in advance at the installation location, with its carrier and pivoting devices ready to engage the roller. This preliminary positioning enables immediate removal when needed, eliminating transportation delays.
3Ease of operation
If manual handling methods are used for roller assembly, then flexibility is maintained, but the operation is time-consuming and requires special care
Solution Approach 1:
The handling apparatus is designed to automatically engage and disengage from the roller and bearing housing through its pivoting mechanisms. The carrier automatically positions itself, and the pivoting devices self-adjust during the removal and installation process, reducing the need for complex manual operations.
Solution Approach 2:
The handling apparatus incorporates dynamic pivoting movements in its carrier and engagement devices, allowing flexible adaptation to the roller's position and orientation. This dynamic capability enables quick engagement and disengagement without rigid, time-consuming alignment procedures.
