AI Technical Summary
The hydraulic test rack for oil drilling tools has a large impact force when testing drilling tools. Internal defects of the tools may not be detected, which may lead to the risk of cylinder explosion. When the internal pressure of the cylinder is high, the plug may fly out, which poses a safety hazard.
A safety protection device for a hydraulic test rack for oil drilling tools was designed, including a top plate and side baffles forming a protective zone, with rolling components and anti-collision pads inside. It utilizes transparent, high-impact-resistant materials, making it easy to observe and move, and reducing the risk of cylinder explosion.
It effectively reduces safety hazards during hydraulic testing, prevents the plug from flying out when the internal pressure of the cylinder is high, and improves the safety and observability of the testing process.
