Intelligent control winch type long-stroke non-beam pumping unit

An intelligent control winch type long-stroke non-beam pumping unit belongs to the technical field of oil and gas development and comprises a winch roller assembly, a roller body axial movement traction system, a numerical control and driving system, a rack assembly and an oil extraction wellhead system. According to the utility model, the service life of the steel wire rope is effectively prolonged, transmission parts are reduced, power is directly taken from the roller body, the hollow traction nut is directly arranged on the roller body, and the roller shaft not only transmits torque, but also serves as a slideway for axial movement of the roller body, so that the whole structure is greatly simplified; therefore, the manufacturing cost and the later maintenance cost are greatly reduced, and the operation reliability and the mechanical efficiency are improved. 一种智能控制绞车式长冲程无游梁抽油机，属于油气开发技术领域，包括绞车滚筒总成，滚筒体轴向移动牵引系统，数控和驱动系统，机架总成以及采油井口系统。本实用新型有效地提高了钢丝绳的使用寿命，减少了传动部件，从滚筒体上直接取力，空心牵引螺母直接设置在滚筒体上，滚筒轴不但传递扭矩，还做为滚筒体轴向运动的滑道
