The invention discloses a buffer device, a crane boom and a crane. The buffer device comprises a first base, a first spring, a swing rod and a rolling wheel; the first base is used for being fixedly arranged on a first base part; one end of the swing rod is hinged to the first base, and the other end of the swing rod is connected with the rolling wheel; the two ends of the first spring are connected with the first base and the swing rod respectively; and the swing rod is configured to enable the rolling wheel to move along the surface of a second base part, and the first spring is configured to change from a natural state to a stretching state when the rolling wheel moves along the surface of the second base part. By means of the buffer device, collision impact between a supporting rod and the boom can be effectively reduced, and safety of equipment and personnel is protected.
本发明公开了一种缓冲装置、起重机臂架以及起重机,所述缓冲装置包括第一底座、第一弹簧、摆杆以及滚轮;所述第一底座用于固定设置在所述第一基件上;所述摆杆的一端铰接于所述第一底座,另一端连接所述滚轮;所述第一弹簧的两端分别连接所述第一底座以及所述摆杆;其中,所述摆杆配置为能够使所述滚轮沿所述第二基件的表面移动,所述第一弹簧配置为能够在所述滚轮沿所述第二基件的表面移动时由自然状态变化为拉伸状态。本发明的缓冲装置能够有效地减小撑杆与臂架之间的碰撞冲击,保护设备及人员的安全。
