Solution Overview

Problem

Existing shaft drilling apparatuses experience significant shaking during operation, leading to deviations in hole position and orientation, affecting the efficiency and precision of drilling and bolt insertion, which compromises the stability and safety of lifting apparatuses.

Innovation Solution

A suspended drilling and bolt mounting system with supporting mechanisms, a wall supporting mechanism, and a driving mechanism that stabilize the main frame during drilling and bolt mounting, ensuring precise hole positioning and bolt insertion by reducing shaking amplitude and maintaining perpendicularity to the shaft walls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a winch works with a sling to drive the drilling apparatus to move in the shaft, then the lifting operation can be performed, but the shaking amplitude of the sling during descending process is large, affecting drilling efficiency and hole position precision

Engineering Contradiction:
Improvelifting operation capabilityVSAvoidhole position precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces a counterweight mechanism as an intermediary element between the winch and the drilling apparatus. The counterweight compensates for the shaking amplitude of the sling during descending process, thereby maintaining hole position precision while preserving lifting operation capability. This mediator absorbs the harmful vibrations and stabilizes the drilling apparatus position.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs damping elements and shock-absorbing mechanisms in advance to cushion the shaking amplitude before it affects the drilling operation. By pre-installing these cushioning elements, the system prepares to mitigate vibrations beforehand, ensuring that hole position precision is maintained even during dynamic lifting and descending operations.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Adaptability or versatility

If the drilling apparatus moves with large shaking amplitude, then the lifting apparatus can operate freely, but the orientation and position of the subsequently inserted bolt deviate, affecting bracket fixation stability

Engineering Contradiction:
Improvelifting apparatus operation freedomVSAvoidbracket fixation stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent incorporates feedback mechanisms that monitor the position and orientation of the drilling apparatus in real-time. This feedback information is used to adjust the drilling parameters and counterweight positioning dynamically, ensuring that even with operation freedom, the bolt insertion position and orientation remain accurate, thereby maintaining bracket fixation stability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent employs dynamic adjustment mechanisms that allow the drilling apparatus to adapt its position and orientation during operation. By making the system dynamic rather than rigid, the apparatus can maintain stability and precision while preserving the freedom of operation for the lifting apparatus.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the main frame is not stabilized during drilling, then the lifting operation can proceed without restrictions, but the shaking amplitude affects drilling efficiency and operational safety

Engineering Contradiction:
Improvelifting operation efficiencyVSAvoidoperational safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent segments the stabilization function from the lifting function by introducing separate counterweight and damping mechanisms. This segmentation allows the lifting operation to proceed efficiently while the dedicated stabilization components work independently to reduce shaking amplitude, thereby maintaining both productivity and operational safety.

Inventive Principle:
Principle #1Segmentation
