Abstract

The embodiment of the invention discloses a winch transmission mechanism for petroleum drilling and a winch. The winch transmission mechanism comprises a rotary drum provided with a rotary drum shaft,wherein the rotary drum is provided with a first side and a second side opposite to each other along the rotary drum shaft; emergency power is arranged on the first side of the rotary drum; a gearboxand a main motor are arranged on the second side of the rotary drum; an output shaft of the gearbox is in transmission connection with the second side of the rotary drum shaft; an output shaft of themain motor is in transmission connection with an input shaft of the gearbox; and the rotary drum shaft, an output shaft of the emergency power, the input shaft of the gearbox, the output shaft of thegearbox and the output shaft of the main motor are positioned on the same straight line. According to the winch provided by the invention, the two-gear planetary gear gearbox is adopted, the winch transmission mechanism has the advantages of small size, light weight and convenience in transportation, and moreover, automatic gear shift of the winch can be realized; and in addition, due to the design of the two-gear speed changing, the maximum load capability of the winch is ensured, and a requirement on the efficiency of the winch also can be met.

Description

technical field [0001] The present application relates to the technical field of oil drilling equipment, in particular, to a winch transmission mechanism and a winch for oil drilling. Background technique [0002] As the core equipment of the drilling rig, the drawworks used for oil drilling can be used as the power source of the lifting mechanism for tripping, tripping, and casing running. The drawworks used in oil drilling are mainly composed of main motor, gearbox, drum, brake, automatic drilling system and so on. The gearbox of the existing oil drilling drawworks usually adopts a two-speed cylindrical external gear gearbox or a one-speed planetary gearbox. [0003] For the cylindrical external meshing gearbox, its volume is large, its quality is heavy, and it is inconvenient to transport. [0004] For the first-speed planetary gearbox, its quality and volume are reduced, but if the winch needs to achieve the same lifting capacity as the cylindrical external mesh gearbo...
