Drill rod rotation driving mechanism of cement soil mixing pile driver
The invention belongs to the technical field of construction equipment, and particularly relates to a drill rod rotation driving mechanism of a cement soil mixing pile driver. The drill rod rotation driving mechanism of the cement soil mixing pile driver solves the problem that stirring is uneven when an existing cement soil mixing pile driver is used for drilling. The drill rod rotation driving mechanism of the cement soil mixing pile mixer comprises a drive box with an inner cavity; the drive box is provided with at least one main drill rod arranged in the vertical direction; at least two auxiliary drill rods are arranged on the outer side of the circumference of the main drill rod; the main drill rod is connected with a main drill rod driving structure capable of driving the main drill rod to rotate in the circumferential direction; an auxiliary drill rod transmission structure is arranged between the main drill rod and the auxiliary drill rods. The drill rod rotation driving mechanism of the cement soil mixing pile driver has the advantages that a single driver can achieve homodromous and reverse-direction movement of the main drill rod and the auxiliary drill rods, so that stirring uniformity is improved; drill rod bodies can axially stretch out and draw back and can axially slide while rotating circumferentially, the phenomenon of being unable to drill is not prone to happening, the perimeter of the cross section of a cement soil mixing pile after construction is increased, and the anti-pulling capacity of the cement soil mixing pile is improved.
