Plugging Device Sliding Wheel Actuation for Hoist Drum
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hiding devices for hoisting machines experience wear and maintenance issues due to relative movements between components during normal operation, leading to increased costs and potential imperfections, especially in shaft and inclined conveyor operations where precise level adjustments are required.
Innovation Solution
A hiding device with a form-fitting, detachable connection using a slide wheel guided on a shaft wheel, actuated by distributed, punctual, and directly acting mechanisms, eliminating the need for a separate adjustment collar and reducing moving masses, with axially adjustable claws and electric adjustment devices for low-maintenance and economical operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sliding collar or adjusting ring is used to engage and disengage the clutch, then the device can be operated, but wear and maintenance costs increase due to constant relative movement between the collar and rotating coupling wheel
Solution Approach 1:
Instead of having a stationary collar move a rotating wheel (conventional approach), the invention inverts the relationship by having rotating actuation elements move with the wheel while acting on a stationary or minimally moving clutch mechanism. This reversal eliminates the sliding friction between moving parts during operation.
Solution Approach 2:
The invention extracts the problematic sliding collar component from the system and replaces it with direct actuation elements that are integrated into the rotating assembly, thereby removing the source of wear and maintenance issues.
2Ease of operation
If a sliding collar guided on the machine frame is used, then engagement and disengagement is enabled, but heating and deformation of components occur due to friction
Solution Approach 1:
The invention replaces the mechanical sliding friction system with a direct actuation mechanism that eliminates continuous contact and friction between moving parts, thereby preventing heat generation and thermal deformation.
3Ease of operation
If a separate adjusting collar or ring is used, then the clutch can be actuated, but the moving mass increases and complexity rises
Solution Approach 1:
The invention merges the actuation function directly into the rotating clutch assembly, eliminating the need for a separate adjusting collar or ring. This integration reduces the number of components and simplifies the overall mechanism.
Solution Approach 2:
The actuation elements serve multiple functions: they engage and disengage the clutch while simultaneously rotating with the wheel, eliminating the need for dedicated separate components for each function.

AI summary
The invention relates to a plugging device for releasably connecting the drum wheel (2) of the at least one loose drum rotatably mounted on the main shaft of a winding engine, said drum wheel being rigidly connected to the loose drum, to the shaft wheel (4) which is rigidly connected to the main shaft. The releasable connection of the drum wheel (2) to the shaft wheel (4) is carried out in a formfitting manner by means of an engageable and disengageable sliding wheel (6) which is guided on a shaft wheel (4). Actuations (10) are carried out in points in a distributed manner over the circumference of the sliding wheel, said actuations acting directly on the sliding wheel (6), in order to engage and disengage the sliding wheel (6).
