The invention provides a swing pulley device and a crane, and relates to the technical field of engineering machines. The swing pulley device comprises a fixed support, a pulley assembly and limitingparts, the pulley assembly is mounted on the fixed support in a swing manner, the limiting parts are mounted at the positions, on the fixed support, of the two sides of the pulley assembly and are used for limiting the swing amplitude of the pulley assembly, and toppling of the pulley assembly is prevented. Due to the fact that the pulley assembly is mounted on the fixed support in a swing manner,the limiting parts are mounted on the fixed support, and are located on the two sides of the pulley assembly, the limiting parts can limit the swing amplitude of the pulley assembly, on one hand, thepulley assembly can carry out swing to a certain degree along with deviating of a steel wire rope, on the other hand, toppling of the pulley assembly due to too large swing amplitude can be avoided,and the use safety of pulleys can be improved.
本发明提供了一种摆动滑轮装置及起重机,涉及工程机械的技术领域,包括固定支座、滑轮组件和限位部;滑轮组件可摆动的安装在固定支座上,在固定支座上且位于滑轮组件的两侧均设置有限位部,限位部用于限制滑轮组件的摆动幅度,以防滑轮组件倾倒。由于滑轮组件可摆动的安装在固定支座上,在固定支座上设置有限位部,限位部位于滑轮组件的两侧,限位部可限制滑轮组件的摆动幅度,一方面滑轮组件可随钢丝绳的偏执进行一定程度的摆动,另一方面又避免了由于滑轮组件的摆动幅度过大而倾倒,提高了滑轮的使用安全性。
