Detailed Description

The present invention will be described in further detail with reference to examples and embodiments.

As shown in fig. 1-4, the tubular pile clamp mechanism of the pile driver comprises a clamping nozzle base body 1, an engagement structure, a clamping mechanism and a limiting structure, wherein the engagement structure comprises a movable tooth 5-1 and a fixed tooth 1-1 which are oppositely arranged, the fixed tooth 1-1 is connected with the clamping nozzle base body 1, the movable tooth 5-1 is connected with a movable plate 5, the movable tooth 5-1 and the fixed tooth 1-1 are fitted with a tubular pile 7 in the shape of an inner side surface, the clamping mechanism comprises an oil cylinder 2 and a swing rod 3 which are mutually connected, the oil cylinder 2 comprises a cylinder body 2-1 and a piston rod 2-2, the swing rod 3 is connected with the movable plate 5, the limiting structure comprises an upper end limiting plate 6 and a lower end limiting block 4 which are oppositely arranged, and the movable plate 5 is positioned between the upper end limiting plate 6 and the lower end limiting block 4.

The middle pin hole of the swing rod 3 is rotatably connected with the pin hole shaft, the lower end hole of the swing rod 3 is connected with the top of a piston rod 2-2 of the oil cylinder 2 through a connecting piece, and the upper end hole of the swing rod 3 is connected with the movable plate 5 through a connecting piece. When the oil cylinder 2 is clamped, the piston rod 2-2 extends forwards to drive the swing rod 3 to rotate around the middle pin hole shaft, and the upper end of the swing rod 3 pushes the moving teeth 5-1 to clamp forwards through the moving plate 5.
