Rotacijski bušili rig kr150a

Maksimalni izlazni moment je 150kN.m, maksimalna dubina bušenja može doseći 52m, a promjer bušenja strojeva također može doseći 1300 mm. The single-cylinder luffing mechanism of this machine has stable operation and is very easy to maintain and repair. The two-segment masts have also been optimized to achieve automatic butt joints and folds, improving efficiency, and helping customers to worry less.In addition, the drilling depth measurement system has been innovated, which has higher accuracy than that of ordinary rigs. The main hoist bottoming protection device (a device that will alarm if the inverted mast is close to the ground) effectively reduces the difficulty of operation and makes the machine Handy when operating machines. The keys of the power head can be used in both directions, and they can continue to be used while they are worn and the other side, which doubles their service life.Very high safety performance, in strict accordance with EU safety standards, meet dynamic and static stability requirements, and ensure safety during construction.Low emissions, environmental protection and energy saving, meet the requirements of most developing and developed countries.The following is an introduction to an engineering case.
Ovaj projekt „Projekt podzemnog koridora elektroenergetske cijevi“ nalazi se u Nanjingu. Projekt je potreban konstrukcija ispod linije visokog napona, tako da postoji visoki ograničeni zahtjev. Prilagođena je rotacijska bušaća. Zbog kupca relativno visokih zahtjeva za mehaničkom opremom i suočavanja sa složenim geološkim uvjetima. Geologija ovog projekta uglavnom je sloj tla, iscrpljena stijena, promjer bušenja 800 mm, dubina bušenja 15m, vrijeme formiranja rupe je oko 25 minuta, općenito, 10 sati konstrukcija tvori 21 rupe, također s visećim čeličnim kavezom u sredini. Formiranje učinkovitosti rupe kao i performanse strojeva za dobivanje prepoznavanja kupaca.
