Is used for drilling equipment, drill can be used to Tapered Rock Bit drill ground water, geothermal energy and so on. And drilling engineering important is security issues, so in the process of drilling, how to prevention and control of drill derrick collapse? The root cause of drill derrick dumping or fall: according to the drilling rig derrick under various conditions of stress characteristic, if the effect on the frequency of the dynamic load on the derrick and the derrick of a certain natural frequency near or into integer times integer times, will cause the derrick, the layout of the resonance caused by dumping derrick or fall.
Drilling technology staff, said the prevention and treatment of drill derrick collapse is mainly the following four elements:
(1) to strengthen the safety management of the worker, let a worker use mastering skills.
(2) strictly abide by the relevant laws and regulations, the worker needs to show certificates, should make the inspection, inspection of equipment in a timely manner.
(3) pay attention to the rig derrick equipment maintenance maintenance, let the equipment always is in a better position, ensure there is no problem in use process.
(4) the unraveling mining drill bit of frequency of the dynamic load on the derrick and the derrick order natural frequency, avoid drill derrick produce resonance condition.
