Abstract

The invention relates to the technical field of oil and gas drilling and geological exploration, in particular to a hydraulic winch and a drilling machine. The hydraulic winch comprises a support and two braking assemblies; the support comprises a box assembly and two end cover assemblies; the box assembly comprises a hollow-inside box and two gear case shells symmetrically connected to the two ends of the box; the two braking assemblies are symmetrically arranged at the two ends of the box; each braking assembly comprises a driving mechanism, a speed reducing mechanism and a braking mechanism; the driving mechanisms are arranged on the end cover assemblies; the speed reducing mechanisms are arranged on the gear case shells; the driving mechanisms are connected with the speed reducing mechanisms; and the braking mechanisms are connected between the driving mechanisms and the speed reducing mechanisms. According to the hydraulic winch, when the hydraulic winch needs to be braked, the braking mechanisms can directly brake the driving mechanisms, because the torque generated by the driving mechanisms is small before being transmitted to the speed reducing mechanisms, braking is easy, braking is flexible, reliable and high in safety, and the hydraulic winch is suitable for being used in large hydraulic winches.

Description

technical field [0001] The invention relates to the technical field of oil and gas drilling and geological exploration, in particular to a hydraulic drawworks and a drilling rig. Background technique [0002] Drilling rig is a mechanical device that drives drilling tools to drill underground to obtain petroleum and physical geological data in oil and gas drilling and geological exploration. Drilling rigs generally include hoisting systems, rotating systems, drilling fluid circulation systems, transmission systems, control systems and monitoring and display instruments, power drive systems, drilling rig bases, and drilling rig auxiliary equipment systems. Wherein, the hoisting system includes a winch, and the winch is used for hoisting and lowering the drilling tool. [0003] A traditional winch includes a drive mechanism, a deceleration mechanism, an actuator, a brake mechanism, and a bracket. When hoisting, the drum of the actuator is wrapped around the steel wire rope, a...
