The invention provides a swing guide pulley yoke and a rotary drilling rig, and relates to the technical field of engineering machinery. The swing guide pulley yoke comprises a swing arm, a pulley yoke body, a large pulley assembly and a rotating device; and the large pulley assembly is rotatably connected to the swing arm, and the swing arm is rotationally connected with the pulley yoke body through the rotating device so that the swing arm can rotate relative to the pulley yoke body. During use, the swing arm and the pulley yoke body are connected through the rotating device so that the swing arm can rotate relative to the pulley yoke body; the large pulley assembly is rotatably connected to the swing arm, and the rope inlet angle of a steel wire rope is reduced through rotation of the swing arm relative to the pulley yoke body while the steel wire rope is guided through the large pulley assembly, so that wear of the steel wire rope is alleviated, and the service life is prolonged; and compared with the prior art, the structure is simple, the weight of the swinging guide pulley yoke can be effectively reduced, and the manufacturing cost is reduced.
本发明提供了一种摆动导向滑轮架和旋挖钻机,涉及工程机械技术领域,包括摆臂、滑轮架架体、大滑轮总成和转动装置;大滑轮总成可转动的连接在摆臂上,摆臂与滑轮架架体通过转动装置转动连接,以使摆臂能够相对于滑轮架架体旋转。使用时,摆臂和滑轮架架体通过转动装置连接,以使摆臂能够相对于滑轮架架体转动,因大滑轮总成可转动地连接在摆臂上,在通过大滑轮总成对钢丝绳进行导向的同时,利用摆臂相对于滑轮架架体的旋转减小钢丝绳的入绳角,进而减缓钢丝绳的磨损,提高使用寿命,与现有技术相比,结构相对简单,且能够有效地减少摆动导向滑轮架的重量,降低制造成本。
