Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation construction, and specifically to a drilling device for pile foundation construction. Background Technique

[0002] Pile foundation construction refers to the construction process of building foundations. A pile foundation consists of piles and a pile cap. In geological exploration work, a relatively small-diameter and relatively deep cylindrical circular hole drilled underground using drilling equipment is also called a borehole. The boreholes for drilling oil, natural gas, and groundwater are relatively larger in diameter. The size of the borehole diameter and depth depends on the burial depth of geological minerals and the purpose of the borehole.

[0003] The patent application with the application number CN202021111461.3 discloses a drilling device for pile foundation construction, including: a base, two sliding rods vertically fixed to the base, a lifting platform sleeved on the two sliding rods, and a top plate fixed to the tops of the two sliding rods; a vertical hydraulic cylinder is fixed to the top plate, the output shaft of the vertical hydraulic cylinder is fixed to the lifting platform, and the lifting platform is of a C-shaped structure.

[0004] In summary, the depth during drilling of this device is limited by the length of the rod itself.

The center of the rotating block 203 slides along the first fixed rod 102, thereby ensuring that the drill rod 2043 can always remain vertical to the ground. The arc rod 2051 fits the outer wall of the drill rod 2043, so that when the drill rod 2043 is recovered after the drilling operation is completed, the soil on the outer surface of the drill rod 2043 is cleaned by the arc rod 2051, thereby ensuring that the drill rod 2043 will not be unable to be recovered by the second hydraulic rod 2041 due to the large amount of soil attached to it.
