Shaker Positioning Device for Automatic Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaker assemblies for dewatering slurries in hydro excavation and drilling fluid reclaimer systems require substantial time to secure and unlock, leading to potential damage and instability during transit due to manual locking processes, which can be forgotten, causing inefficiency and safety issues.
Innovation Solution
A shaker assembly with a vibratory frame and subframe, equipped with an isolation device for vibration damping and a positioning device that guides the frame between raised and lowered positions, combined with an actuator for automatic locking of the vibratory frame to the subframe, ensuring secure positioning during transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual locking mechanism is used to secure the vibratory frame to the subframe, then the locking function is achieved, but the operation time is excessive and operator error may occur
Solution Approach 1:
The system uses the isolation device's own motion (lowering the vibratory frame) to automatically trigger the locking mechanism. The positioning device detects when the frame reaches the lowered position and automatically engages the locking mechanism, eliminating the need for separate manual locking operations.
Solution Approach 2:
The locking mechanism is pre-positioned and ready to engage. The positioning device is pre-configured to detect the lowered position of the vibratory frame. When the isolation device lowers the frame, the locking mechanism automatically engages at the predetermined position without requiring additional manual intervention.
2Reliability
If manual locking mechanism is used, then the locking function is achieved, but operator forgetfulness may cause damage or instability during transport
Solution Approach 1:
The locking system serves itself by automatically detecting when the vibratory frame is in the lowered position and engaging the locking mechanism without requiring operator attention or memory. The system ensures locking occurs automatically, eliminating forgetfulness-related safety issues.
Solution Approach 2:
The positioning device provides feedback about the vibratory frame's position to the locking mechanism. When the frame reaches the lowered position, the positioning device signals the locking mechanism to engage, creating a closed-loop system that ensures proper locking without operator intervention.
3Adaptability or versatility
If the vibratory frame is not securely locked during transport, then mobility is maintained, but damage to the shaker assembly may occur
Solution Approach 1:
The system dynamically adjusts between operational mode (isolation device raised, frame movable) and transport mode (isolation device lowered, frame locked). The automatic locking mechanism engages only when needed during transport, maintaining operational flexibility while preventing damage during transit.

AI summary
Shaker assemblies for dewatering slurries are disclosed. The shaker assemblies may include a positioning device which limits movement of the vibratory frame of the shaker assembly relative to a subframe when the vibratory frame is moved from a raised operating position to a lowered position. The positioning device may guide the vibratory frame as it is lowered from the raised position to the lowered position. In some embodiments, the shaker assembly includes a locking device for locking the vibratory frame to the subframe when the vibratory frame is in the lowered position.
