AI Technical Summary
The safety devices of existing bridge maintenance truss vehicles have problems such as structural corrosion and mechanical damage, which lead to sudden high-altitude fall accidents during use, causing safety risks for maintenance personnel.
A personnel safety device including rollers, connecting steel pipes, roller gear adjustment device, seat belt retracting and seat belts are designed. The roller is in a rolling contact with the I-shaped steel rail, the roller is rotatably connected to the connecting steel pipe, the connecting steel pipe is fixedly connected to the roller wheel pitch adjustment device, the wheel pitch adjustment device is connected to the seat belt retracting device, and the seat belt retracting device is wound on the seat belt retracting device. The device ensures use on different I-ray rail models through roller pitch adjustment and seat belt retraction and retracting devices, and provides emergency braking in emergencies.
This device can ensure the safety of maintenance personnel during the bridge maintenance process, prevent fall accidents, and is suitable for different models of I-shaped rails, expanding the scope of application.
