Abstract

The invention discloses an installation tool of a gear drill tooth. The installation tool comprises a clamping base, the clamping base comprises a body and backing plates used for limiting the installation angle of the gear drill tooth, the body is of a hollow structure used for containing the gear drill tooth, the body comprises side walls and top walls used for limiting the installation angle of the gear drill tooth, clamping grooves used for being connected with a drill bit cylinder in a clamped mode are formed in bottom ends of the side walls of the body, the backing plate are connected with the body, and the inclination angles of the backing plates are identical with the installation angle of the gear drill tooth. According to the installation tool of the gear drill tooth, the top walls of the clamping base and the backing plates can be utilized to limit the installation height and the installation angle of the drill tooth so that the angle and height for tooth distribution are unified, and gear teeth are high in arrangement and installation efficiency and unified in position.

Description

technical field [0001] The invention relates to the technical field of drill bits, in particular to a roller cone bit installation tool. Background technique [0002] In the design and construction of construction projects at home and abroad, most of the foundation treatment adopts cast-in-situ pile foundation. With the increase of the requirements for the foundation load of buildings, such as: high-rise buildings, bridges, ports, foundations of large equipment, etc., pile holes are required to be inserted into hard piles. The rock layer has a certain depth. Affected by rock strength, common drilling tools have low rock entry efficiency and large wear of drill teeth. In hard rock formations, cone drills are often used for pile hole construction. The cone is an easy-to-wear part. When drilling in hard rock formations, one cone is lost per rock meter, and a large number of cone teeth are consumed in the entire pile hole construction. Affected by the shape of the teeth of the...
