Description

Technical Field

[0001] This utility model relates to the field of geological exploration drill pipe technology, specifically a drill pipe device for geological exploration in mining. Background Technology

[0002] Geological drill pipe is a core component of geological drilling tools, connecting the drill bit and transmitting power, and is an important part of the drill string. Its body is made of special alloy steel, and the DZ series steel drill pipe body is combined with alloy structural steel joints through friction welding, with heat treatment ensuring material properties [1-3]. Its basic functions include applying drilling pressure, transporting drilling fluid, and handling special downhole operations, and its applications cover geological exploration fields such as core drilling.

[0003] Currently, existing drilling rod devices for geological exploration in mines typically use a connection structure between the power structure and the drill bit to transmit power from the power structure to the drill bit. However, in actual mine geological exploration operations, the drill rod needs to be extended in length through multiple connections to meet the drilling requirements at different depths. The currently commonly used connection structure has poor connection stability, resulting in a problem with the instability of the drill rod connection structure. Furthermore, a single drill bit is difficult to handle diverse strata such as soft soil, fractured zones, and hard rock, requiring frequent replacements. The existing connection between the drill bit and the drill rod is bolted, which is not convenient for quick disassembly, resulting in the problem of not being able to easily assemble and disassemble the drill bit and the drill rod.

The outer side of the threaded sleeve 3 is provided with anti-slip patterns.

[0027] Please refer to Figure 1 to Figure 2 , Figure 4 , Figure 5 A limiting block 17 is fixedly connected to the inner side of the connector 2, and a limiting groove 15 is opened on the outer side of the plug 11. The limiting block 17 is connected to the limiting groove 15, and the limiting block 17 is distributed in a ring array.

[0028] Specifically, the limiting slot 15 fits closely with the limiting block 17.

[0029] Please refer to Figure 1 to Figure 2 , Figure 4 , Figure 5 Another plug 11 is fixedly connected to the upper end of the connecting rod 1. The upper part of the plug 11 is provided with a structure that connects to the connector 2. The limiting block 8 is rectangular.

[0030] Specifically, the two ends of the connecting rod 1 are the plug 11 and the connector 2, respectively, and the limiting block 8 and the limiting groove 16 fit closely together.

[0031] Please see Figures 1 to 3 The buckle structure consists of a plug rod 12, a stop block 13 and a support spring. The lower part of the plug rod 12 is connected to the fixing block 5, the upper end of the plug rod 12 is inserted into the interior of the fixing plate 4, and the lower part of the stop block 13 is fitted with the fixing plate 4.

[0032] Specifically, the upper part of the stop block 13 is provided with an outwardly inclined chamfer, and a supporting spring is provided between the stop block 13 and the insert rod 12. The stop block 13 is made of a metal material with high hardness.

[0033] Please see Figures 1 to 3 The plug 11 is slidably connected to a movable frame 7, which has an opening corresponding to the plug rod 12. The lower part of the movable frame 7 presses against the stop block 13.

[0036] Specifically, the connecting block 10 fits closely with the connecting groove 9.

[0037] When multiple drill rods need to be connected, the connector 2 at the lower end of the connecting rod 1 is connected to the plug 11 at the upper end of another connecting rod 1. The plug 11 is inserted into the interior of the connector 2, and the limiting block 8 inside the connector 2 is inserted into the limiting groove 16 inside the plug 11.
