The invention discloses an automatic rotation locking device of a crane. The automatic rotation locking device comprises a locking rack and a driving device, wherein the driving device comprises at least one group of transverse driving devices and at least one group of radial driving devices; the at least one group of transverse driving devices are arranged on one side or two sides of the side surfaces of two sides of the locking rack; the locking rack is connected with the transverse driving devices and is driven by the transverse driving devices to freely slide along the horizontal transverse direction; the at least one group of radial driving devices are arranged on one side, which is far away from a large gear ring, of the locking rack; the locking rack is connected with the radial driving devices and is driven by the radial driving devices to freely slide along the radial direction of the large gear ring; and the locking rack is connected with the transverse driving devices and the radial driving devices by adopting sliding mechanisms respectively, so that the locking rack is relatively fixed in the driving direction of the driving device and can slide back and forth along thedirection vertical to the driving direction. According to the automatic rotation locking device disclosed by the invention, a rotation locking function can be provided during normal working of the crane, and the working safety of a floating crane is improved.
本发明公开了一种起重机自动回转锁定装置,包含锁定齿条和驱动装置,驱动装置包含至少一组横向驱动装置和至少一组径向驱动装置,至少一组横向驱动装置设置在锁紧齿条两侧侧面的一侧或两侧,锁定齿条与横向驱动装置连接由横向驱动装置驱动沿水平横向自由滑动,至少一组径向驱动装置设置在锁定齿条远离大齿圈的一侧,锁定齿条与径向驱动装置连接由径向驱动装置驱动沿大齿圈径向自由滑动,锁定齿条与横向驱动装置和径向驱动装置分别采用滑动机构连接使锁紧齿条在驱动装置在驱动方向上相对固定并且能够沿着与驱动方向垂直的方向来回滑动。本发明可以在起重机正常工作期间提供回转锁定功能提高浮式起重机工作安全性。
