| Abstract:This paper introduces the overall structure of new STC-1000 collocated double-hoister truck mounted drilling rig. With the collocated double hoisters, the drilling rig has compact structure and reasonable layout, the hoisters can be used interchangeably, winding, lifting and braking are convenient and reliable; the pulley centering of double-hoister lifting is solved by movable sheave group; explosion relief valve is used in derrick take-off and landing circuit to optimize the hydraulic system. The working efficiency is improved by the above application, the relocation has become convenient and rapid, and the auxiliary time is greatly shortened. |
