Dynamic compaction machine and winding device thereof
The invention discloses a winding device used for a dynamic compaction machine. The winding device comprises a winch and further comprises a detecting device connected to the top end of a cantilever crane and a control system connected to the detecting device. The detecting device is used for measuring the distance between the top end of the cantilever crane and the top end of a rammer and the distance between the top end of the cantilever crane and the position of an adjacent reference point of a ground rammer falling point and sending the distances to the control system. The control system is used for receiving measuring information sent by the detecting device and calculating the ramming volume according to the formula: Hs=Hc+L1-L2cosalpha , wherein Hc is the height of the rammer, L1 is the distance between the top of the rammer after ramming is conducted and the detecting device at the top end of the cantilever crane, L2 is the distance between the detecting device and the adjacent reference point of the ground hammer falling point, alpha is the included angle between the connecting line formed by the detecting device and the reference point and the vertically-downward plane, and Hs is the ramming volume. According to the winding device, due to the fact that the distance between the rammer and the top end of the cantilever crane is directly measured, the ramming volume calculated accordingly is more accurate. The invention further provides the dynamic compaction machine comprising the winding device, and the dynamic compaction machine can be used for accurately measuring the ramming volume of the rammer.
