Axial lifting driving structure for drill rods of pile driver for cement mixing piles
The invention belongs to the technical field of building equipment, and particularly relates to an axial lifting driving structure for drill rods of a pile driver for cement mixing piles. The problem that an existing pile driver for cement mixing piles cannot achieve drilling properly is solved. The axial lifting driving structure comprises a driving box body with an inner cavity. The driving box body is provided with at least one drill rod body which is arranged in the vertical direction and can rotate circumferentially. One end of the drill rod body penetrates in the driving box body. An axial driving mechanism is arranged between the drill rod body and the driving box body, wherein the axial driving mechanism can drive the drill rod body to vertically slide in a reciprocating mode when the drill rod body is in a circumferentially-rotary state or in a circumferentially-stationary state. The axial lifting driving structure for the drill rods of the pile driver for the cement mixing piles has the advantages that the drill rod body can be stretched in the axial direction and also can slide in the axial direction during circumferential rotation, and the phenomenon that drilling cannot be achieved tends not to happen; drilling efficiency is improved, the perimeter of the cross section of each cement mixing pile is increased after construction, the pull-out capacity of the cement mixing piles is improved, and the mixing homogeneity is improved as well.
