For the application of drilling rigs, it is not only stipulated to improve its working efficiency, but also the problem of safety factor is more critical in all matters. Then, what problems should be paid attention to in the whole process of engineering construction of drilling rigs? Here is a detailed introduction for everyone.
The drilling machine adopts front and back circulation system, with top drive technology, rotary drilling, full-automatic loading and unloading of drilling tools, compact structure, convenient transportation, easy actual operation and faster footage speed. Up and down 30m per hour. High efficiency, low price, easy to use and other characteristics, is the ideal new punching equipment. It is suitable for the geological structure of plain area, hilly terrain and mountainous area. It is an idealized equipment for deep water well, pile hole of house highway bridge foundation, engineering construction, soil temperature central air conditioning, rainfall of engineering project, and geological structure exploration engineering construction.
In the whole process of drilling engineering construction, it is often encountered that equipment has any problems that must be overhauled and maintained, such as repairing drilling mud pump, connecting transmission chain, repairing gas supply, power supply circuit and diesel engine. During equipment maintenance or overhaul, if the drilling tool is in the mine, the circulating system of the killing fluid should be maintained as much as possible and the drilling tool should be subject to movement. If neither the circulating system nor the drilling tool can be subject to movement, 2/3 of the net weight of the drilling tool should be pressed on the pipe well, resulting in several bending of the drill string to reduce the chance of sticking.
At the automatic switch of the overhauled equipment, the brand of "overhauled and no moving" should be hung up, and personnel should be sent to monitor to avoid operation errors. However, when the pneumatic operation equipment is overhauled, it should be ensured that the air supply is reasonable. When necessary, the main air source pipeline should be removed to ensure safety. After that, after careful investigation and analysis by the safety accident investigation team, it was determined that the internal hydraulic seal of the gas relay, which is the normally closed use method of controlling the clutch of the transmission system, damaged the air blockage. When a certain working pressure is accumulated, the gas relay has its own effect, connecting the air source with the pneumatic tire channel of the clutch of the winch transmission system, and pushing the winch to rotate. Because there is no main air source (the air power switch is not closed), the winch will automatically terminate after only turning the driving force for two turns. After the on-the-spot experiment confirmed, the above reason is beyond doubt.
The whole construction process of the drilling machine of the engineering project is relatively complicated. If you want to carry out the whole drilling process more successfully, you need to pay more attention to the problem of safety factor. I believe that according to the detailed introduction above, everyone has a general understanding of the operation safety of the drilling machine.
