The Conveyer of Noise-Reduced and Srash-Proof Drill Pipe
Abstract: It is adopted to establish structure of reducing-noise and avoiding-collision in the drilling tools bent, and it can decrease contact force among drilling tools, so it can reduce noise pollution by drilling tools collision, and finally it can improve working environment which is based on noise pollution in the drilling tools producing workplace. According to smart designed unpowered crash-proof structure, drilling tools can achieve automatic resilience depending on self-gravitation, and obtain blocking to the next drilling tool through gravity of the prior drilling tool. Thus, it can reduce noise intensity of drilling tools collision. Through on-site monitoring, the device can make noise low-order peak value decrease 30.6%; the noise is caused by drilling tools collision compared with conventional drill pipe collision. Noise mean value decreased 24.7%. High peak value declined 31.1 %. Obvious effects are gained when noise mean value decreases 32.9 %. Meanwhile the device has simple structure, and can be easily used; moreover, it has high value to be promoted.
