Abstract
A triangular drill rod comprises a rod body with a section in a regular triangle shape. Chip grooves are formed in the three side faces of the rod body in the length direction of the rod body, a connector is arranged at one end of the rod body, a connecting hole is formed in the other end of the rod body, the connector is composed of a fastening head with external threads and a locating head fixedly arranged at the front end of the fastening head, the fastening head and the locating head are both cylindrical, the diameter of the fastening head is larger than that of the locating head, the length of the locating head is larger than that of the fastening head, the connecting hole is composed of a fastening hole with internal threads and a locating hole formed in the rear end of the fastening hole, and the connector is matched with the connecting hole. The triangular drill rod is simple in structure, reasonable in design and low in cost, and is provided with a locating structure, the drill rod can be accurately mounted, mounting errors are reduced, and the service life of the drill rod is prolonged; the chip grooves are formed, and therefore chip discharging is more smooth; a cooling hole is formed, a cooling water pipe can be connected into the cooling hole, and therefore the triangular drill rod is convenient and fast to use.
Description
Technical field
The utility model relates to a kind of mining drilling device, especially relates to a kind of triangle drilling rod.
Background technology
In engineering geology and mineral reserve probing, be widely used triangular drill rod, but what adopt due to the connected mode of tool joint place is that male and female is threaded, due to when mounted, owing to there is no positioner or locating in rundown process, cause like this location not good, often cause drilling rod to have certain alignment error, make the drilling rod after installing, occur that minute angle tilts, when drilling rod is worked, affect drilling life of drill pipe, and three faces are plane, chip removal is not smooth, affect operating efficiency, and the boring effect.
