Description

Technical Field

[0001] The present invention relates to the technical field of drill pipes, specifically rib drill pipes. Background Art

[0002] Rib drill pipes belong to the subdivision of geological spiral drill pipes. Their specific characteristics are: using geological drill pipes as the pipe body, welded with prestressed winding planar spiral blades; they can be divided into single spiral, double spiral, and triple spiral types according to the type of spiral blades. This drill pipe has the characteristics of high strength, good powder discharging ability, and strong ability to handle in-hole accidents. It is clamped by a gripper, with simple operation and low labor intensity for workers.

[0003] However, in the prior art, the joints of rib drill pipes are prone to cracking during the drilling process, and the spiral blades arranged on the outside of the drill pipes are prone to wear, often resulting in the inability of the gripper to clamp, affecting the drilling efficiency and increasing the production cost. Summary of the Invention

[0004] To solve the problems that the joints of the above rib drill pipes are prone to cracking and the spiral blades are prone to wear, the present invention provides a rib drill pipe.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a rib drill pipe, including a drill pipe body and a connecting rod. The connecting rod is arranged at the left end of the drill pipe body. The drill pipe body includes a main rod and spiral fins. A connecting piece is provided on the connecting rod. A connecting groove is provided inside the left end of the drill pipe body. The connecting groove and the connecting piece are correspondingly arranged, and both the connecting groove and the connecting piece are provided with several.

[0006] As an optimization, a first fixing plate is provided at the left end of the main rod, a second fixing plate is provided at the right end of the main rod. Fixing columns are provided on the first fixing plate, fixing grooves are provided on the second fixing plate, and both the fixing columns and the fixing grooves are provided with several. The connecting rod is arranged on the second fixing plate.

[0007] As an optimization, both the connecting groove and the connecting piece are provided with two. The two connecting pieces are centrosymmetric, the two connecting grooves are centrosymmetric, and a buffer block is provided at the bottom of the connecting groove.

[0008] As an optimization, a screw hole is provided at the left end of the fixing column, and a screw is provided on the screw hole.

[0009] As an optimization, the spiral fin includes an upper edge fin, a lower edge fin, and a protruding fin. The protruding fin is arranged between the upper edge fin and the lower edge fin, and the protruding fin, the lower edge fin, and the upper edge fin are integrally formed.

[0010] As an optimization, fixed teeth are evenly arranged on the protruding wing. The bottom of the fixed teeth is fixedly connected to the protruding wing. The top of the fixed teeth is provided with a front narrow surface and a rear arc surface. The front narrow surface is arranged on the front side of the spiral direction of the spiral blade, and the length of the front narrow surface is less than the length of the rear arc surface.

[0011] As an optimization, the height of the upper edge wing and the lower edge wing is greater than the height of the protruding wing, and both the upper edge wing edge and the lower edge wing edge protrude outward to form pointed parts.

[0012] As an optimization, the spiral direction of the connecting piece is the same as the spiral direction of the spiral blade.

[0013] As an optimization, the buffer block is made of rubber material.

[0014] The overall beneficial effect of this solution is as follows: For the rib drill pipe, through the cooperation of the connecting piece on the connecting rod and the connecting groove of the drill pipe body, adjacent drill pipes are assisted in connection, and at the same time, the first fixing plate and the second fixing plate at both ends of the drill pipe body are used for fixed connection, which can strengthen the firmness of the connection between adjacent drill pipes; at the same time, buffer blocks are arranged at the bottom of the two connecting grooves, which can disperse and buffer the rotational force received by the drill pipe when the drill pipe rotates, effectively preventing the connection of the drill pipe from cracking during the drilling process; by setting the spiral blade into the structure of the upper edge wing, the protruding wing and the lower edge wing, and setting fixed teeth on the protruding wing, efficient drilling can be carried out through three layers of blades, and at the same time, the drilling effect of the drill pipe body is greatly improved through the action of the fixed teeth; when the drill pipe body is drilling, even if the fixed teeth are worn, the upper edge wing and the lower edge wing can still carry out efficient drilling. This device not only greatly improves the drilling efficiency of the drill pipe body, but also effectively extends the service time of the drill pipe body and reduces the production cost.
