Powerful tamping automatic hook and unhook device

Abstract

The invention discloses a dynamic compaction automatic hook unhooking device which comprises a main body (1), a hook clamp (2), a connecting plate (3), a guide opening (4), a triangular clamping plate (6), an unhooking spring (7), a guide rod (10) and a hydraulic cylinder (11). One end of the hook clamp (2) is installed on the main body (1) through a lug clamping plate (5), the other end of the hook clamp (2) is connected with the triangular clamping plate (6) through the connecting plate (3), and the guide opening (4) is arranged at the bottom of the main body (1). The triangular clamping plate (6), the guide rod (10) and the hydraulic cylinder (11) are installed in the main body (1), the triangular clamping plate (6) is installed at the lower end of the guide rod (10), the upper end of the guide rod (10) is connected with a piston rod of the hydraulic cylinder (11), and the unhooking spring (7) is installed on the guide rod (10). The dynamic compaction automatic hook unhooking device has the advantages of being free of a power source, a pipeline and a hanging rope, performing automatic hooking and unhooking and needing no manual assistance.

Description

technical field [0001] The invention relates to a dynamic ram automatic hook unhook device. Background technique [0002] In the prior art, the dynamic compaction operation requires frequent repetition of the rammer hook. At present, the hook form of an ordinary crane is used. During the operation, the lever is manually operated to make the hook in the swing lock position, and the hook lifts the rammer. The outer end of the lever is tied with a wire rope, and the other end of the wire rope is fixed on the body of the dynamic ram. After reaching the set height, the wire rope is tightened, the lever is pulled to leave the set position, the hook swings, and the rammer falls freely. This method exists The problem is that the swing is large, and it is easy to collide with the boom frame, causing danger; it is necessary to manually reset the hook on the lever, which is labor-intensive, dangerous, and low in work efficiency; it is time-consuming and inconvenient to adjust the heigh...
