Problem
Existing climbing robots for electric power operations have limited avoidance range and functionality, struggling to efficiently climb and retighten bolts on angle steel towers due to obstacles like long foot nails and connecting plates.
Innovation Solution
A multifunctional climbing operation platform equipped with a clamping device having claw bars that open beyond 180 degrees, a bolt retightening device capable of replacing different sleeves, and an auxiliary sleeve replacement box, allowing for wider avoidance and simultaneous climbing, bolt retightening, and sleeve replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the clamping jaws have a limited opening angle to clamp the angle steel firmly, then the clamping force is sufficient, but the avoidance range for obstacles like long foot nails and connecting plates is small
Solution Approach 1:
The clamping device is divided into multiple independent clamping units, each with its own adjustable clamping jaws. This segmentation allows different parts of the clamping device to perform different functions: some units maintain firm clamping while others open to avoid obstacles, resolving the contradiction between clamping stability and avoidance range
Solution Approach 2:
The clamping jaws are designed with dynamic adjustment capability, allowing the opening angle to be changed from a fixed limited angle to an adjustable range that can exceed 180 degrees. This dynamic adjustment enables the system to switch between firm clamping mode and obstacle avoidance mode, simultaneously achieving both clamping stability and wide avoidance range
2Adaptability or versatility
If the V-shaped portion is fixed to press against the angle steel edge, then the climbing structure is simple, but it cannot avoid connecting plates and requires complicated posture adjustments
Solution Approach 1:
The fixed V-shaped portion is replaced with movable clamping jaws that can dynamically adjust their position and opening angle. This dynamic design allows the clamping device to automatically adapt to different obstacles like connecting plates without requiring complex posture adjustments of the entire climbing robot
Solution Approach 2:
The movable clamping jaws serve multiple functions: they can clamp firmly on angle steel surfaces, open wide to avoid obstacles like connecting plates and foot nails, and adjust to different positions. This multi-functionality replaces the need for separate avoidance mechanisms, maintaining structural simplicity while enhancing adaptability
3Productivity
If manual retightening of connecting bolts is performed, then the operation can be completed, but the danger coefficient is high, labor intensity is high, and efficiency is low
Solution Approach 1:
The climbing robot is equipped with an automatic bolt retightening device that performs the retightening operation autonomously without human intervention. The device includes a bolt tightening mechanism with adjustable torque parameters, enabling the robot to self-service the retightening task while eliminating the high safety risks and labor intensity associated with manual operations
Solution Approach 2:
The manual mechanical retightening operation is replaced with an automated mechanical system integrated into the climbing robot. This system uses motor-driven bolt tightening mechanisms with controllable torque, substituting human physical effort and improving both safety and efficiency
4Adaptability or versatility
If the fastening tool is fixed for one bolt specification, then the structure is simple, but it cannot fasten bolts of different specifications and requires returning to ground for sleeve replacement
Solution Approach 1:
The fastening tool is designed with universal adaptability to handle multiple bolt specifications. The tool includes interchangeable sleeves or adjustable components that can be quickly replaced on-site, enabling the climbing robot to fasten different bolt sizes without returning to the ground, thus reducing time loss while maintaining operational simplicity
Solution Approach 2:
Multiple sleeves for different bolt specifications are pre-loaded into the fastening tool before climbing. This preliminary preparation allows the robot to immediately switch between different bolt sizes during operation without returning to the ground for replacement, significantly reducing time loss while maintaining structural simplicity
