Dynamic compactor and hydraulic rotating head locking structure thereof
The invention discloses a dynamic compactor and a hydraulic rotating head locking structure thereof. The hydraulic rotating head locking structure comprises a rotating shaft, a locking plate, a hydraulic rotating joint and a fastener, wherein the rotating shaft is provided with a center positioning hole and a radial positioning hole; the locking plate is located on the shaft end surface of the rotating shaft and is provided with a positioning hole and a fastening hole; the hydraulic rotating joint comprises a middle body which is axially provided with a first column segment and a second columnsegment, the diameter of the first column segment is smaller than that of the second column segment, the first column segment penetrating the positioning hole is locked to the center positioning hole, and the second column segment is matched with the positioning hole; and the fastener is used for locking the coaxial fastening hole to the radial positioning hole, so that the rotating shaft, the locking plate and the middle body are fixedly connected. The hydraulic rotating head locking structure can make sure that the hydraulic rotating joint will not loosen and fall off when the rotating shaft is started and stopped emergently, vibrates at a high frequency and switches between forward and backward rotation frequently.
本发明公开了一种强夯机及其液压旋转头防松结构，液压旋转头防松结构包括：旋转轴，旋转轴设有中心定位孔和径向定位孔；锁片，锁片位于旋转轴的轴端面，锁片设有定位孔和紧固孔；液压旋转接头，液压旋转接头包括中间体，中间体沿轴向设置有第一柱段和第二柱段，第一柱段的直径小于第二柱段的直径；第一柱段用以穿设定位孔后和中心定位孔锁紧，第二柱段用以和定位孔配合；紧固件，紧固件用以将同轴的紧固孔和径向定位孔锁紧，以使旋转轴、锁片和中间体三者固定连接。上述液压旋转头防松结构，可以确保旋转轴在急起急停、高频率振动以及频繁正反转切换时，液压旋转接头不会松动脱落。
