Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rock mechanics testers require manual effort and external tools for unloading and cleaning rock fragments, making the process laborious and time-consuming.
Innovation Solution
A multi-shaft pressurized rock mechanics tester with two gear racks for power transmission, allowing the fence frame to slide downward and engage driven gears to overturn and unload the bracket plate, reducing the need for manual effort and simplifying the unloading process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual effort and external tools are used for unloading and cleaning rock fragments, then the unloading process can be completed, but the operation becomes laborious and time-consuming
Solution Approach 1:
The fence frame is designed to automatically drive the bracket plate to overturn and unload rock fragments through its own downward sliding motion, eliminating the need for external tools and manual labor. The system uses itself as the driving force for unloading, transforming from a manual operation to an automated self-service process.
Solution Approach 2:
The gear rack and driven gear mechanism serves as an intermediary that converts the downward sliding motion of the fence frame into rotational motion of the bracket plate. This mechanical intermediary enables the automatic overturning and unloading function, bridging the gap between the fence frame's linear motion and the bracket plate's rotational motion.
2Extent of automation
If additional manual labor is required for overturning the bracket plate, then the unloading can be achieved, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The fence frame's downward sliding motion automatically drives the bracket plate to overturn through the gear rack and driven gear mechanism, achieving full automation of the unloading process without requiring additional manual labor or complex external mechanisms.
Solution Approach 2:
The fence frame serves multiple functions: it provides structural support during testing, contains rock fragments during compression, and automatically drives the overturning mechanism for unloading. This multi-functionality reduces the need for separate dedicated unloading mechanisms, simplifying the overall device structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables convenient and quick unloading and cleaning of rock fragments by automating the overturning of the bracket plate, saving time and labor, and facilitating the operation through a double-crank sliding bar mechanism for easy access.
Implementation Method 1
two gear racks are symmetrically welded in both sides on the top of the rear panel of fence frame and will get engaged and contacted with the two driven gears while the fence frame slides down with interference
Implementation Method 2
four hydraulic cylinders are locked, fixed and hoisted on the bottom of the I-shaped installation plate with screws, a square press plate is locked, fixed and hoisted at the bottom of four piston shafts on the four hydraulic cylinders with screws, and a jacking pillar is welded and fixed at the bottom center of the square press plate and slides down to contact the rock block to be tested
Implementation Method 3
two L-shaped inserts are installed on the two six-edge positioning shafts by pushing and sliding a first set of spring on the top
