Crane and counter weight thereof
The invention belongs to the field of cranes, and discloses a crane and a heavy hammer thereof, and the crane and the heavy hammer thereof comprise a connecting cover used for being connected to a crane hook; the hammer body is located below the connecting cover, the hammer body is provided with a vertical through hole capable of being arranged on a lifting mechanism of the crane in a sleeving mode, and the hammer body can be automatically connected with the connecting cover in a buckled mode under the lifting effect of the lifting mechanism. A pile pipe containing groove capable of being matched with a pile pipe in an aligned mode is formed in the bottom of the hammer body. The crane comprises a heavy hammer and a lifting mechanism, the lifting mechanism is a telescopic rod, the upper end of the lifting mechanism is connected with the connecting cover, the lower end of the lifting mechanism downwards penetrates through the vertical through hole, a lower end limiting block is arranged at the lower end of the lifting mechanism, and the diameter of the lower end limiting block is larger than that of the vertical through hole. The crane and the heavy hammer thereof are simple in structure, convenient to operate and capable of achieving automatic hooking and piling functions.
本发明属于起重机领域，公开了一种起重机及其重锤，该起重机及其重锤包括：连接盖，用于连接在起重机吊钩上；和锤体，位于连接盖的下方，锤体设有能够套设在起重机的提升机构上的竖向贯通孔，锤体能够在提升机构的提升作用下与连接盖自动卡扣连接。锤体的底部设有能够与桩管对位配合的桩管容置槽。起重机包括重锤和提升机构，提升机构为伸缩杆，提升机构的上端与连接盖连接，提升机构的下端向下穿过竖向贯通孔，提升机构的下端设有下端限位块，下端限位块的直径大于竖向贯通孔的直径。本发明的起重机及其重锤结构简单，操作便捷，能够实现自动挂钩和打桩功能。
