Description

Technical Field

[0001] The utility model relates to the technical field of rotary drilling rigs, in particular to a rotary drilling rig for infrastructure construction. Background Art

[0002] A rotary drilling rig, also known as a pile driver, is a comprehensive drilling rig. The construction technology of a rotary drilling rig is a relatively advanced pile foundation construction technology in my country in recent years. It is known as the "green construction technology" and is characterized by automatic positioning, vertical hole drilling, fast hole-making speed, less pollution, and strong maneuverability. A rotary drilling rig is generally suitable for clay, silt, sand, artificial backfill soil, and some pebble and gravel strata, and is widely used in the construction of various foundation infrastructure such as bored piles, continuous walls, and foundation reinforcement.

[0003] After searching, the Chinese patent announcement number CN219431768U discloses a new type of rotary drilling rig. This patent adopts the cooperation between the limit connection unit and the driving drilling unit to solve the problems of the prior art such as complicated operation, increased manual labor and affected work efficiency. Through the driving setting of the driving motor, the threaded rod can be driven to rotate. Under the limiting action of the limit groove, the limit sleeve can drive the height of the drill rod to be raised and lowered, and it can be adapted and adjusted according to the construction land conditions to ensure stable connection with the ground, thereby preventing the rotary drilling rig from being unstable in the center and easily tipping over during rotary drilling operations.

[0004] The above patent fixes the equipment by inserting the drill rod into the ground to prevent tipping over. However, after the drill rod is extended from the ground, some soil will adhere to the outer wall. When the soil has a certain humidity, the drill rod will be corroded faster, which will affect its service life. Utility Model Content
