Description

Technical Field

[0001] This application relates to the technical field of taphole drill connecting devices, and particularly relates to a taphole drill connecting sleeve. Background Art

[0002] The taphole drill is an important machine for opening the taphole during the tapping of the blast furnace. Essentially, the taphole drill is a long rod electric drill that can rotate and move forward and backward and is suspended by a cantilever. The taphole drills adopted at home and abroad mainly include five types: suspended electric taphole drills, fully pneumatic taphole drills, gas-liquid compound drive taphole drills, fully electric taphole drills, and fully hydraulic taphole drills.

[0003] During the process of opening the taphole, a connecting sleeve is required to connect the drill pipe for drilling. During the process of opening the taphole, nitrogen is used to blow out the fine debris of the drilled gun mud in the taphole passage. When the taphole is just opened, the fine slag and iron splashing out from the taphole are likely to enter the gap between the connecting sleeve and the positioning ring, causing the connecting sleeve to get stuck, unable to transmit torque in time, resulting in jamming during the opening of the taphole, or when the taphole is just opened, the drill pipe cannot be pushed out in time, delaying the opening of the taphole, affecting the discharge of slag and iron in the blast furnace, and being unfavorable for the long-term stable operation of the blast furnace. The fine slag and iron debris and the fine debris of the gun mud accumulate in the gap between the connecting sleeve and the positioning ring, causing the connecting sleeve to wear faster, reducing its service life, and the large particles of slag are more likely to jam the connecting sleeve. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a taphole drill connecting sleeve, which is used to solve the problems that during the opening of the taphole by the taphole drill in the prior art, the fine slag and iron debris and the fine debris of the gun mud splash into the gap between the positioning ring and the diameter of the connecting sleeve, resulting in the jamming of the connecting sleeve and the wear of the connecting sleeve.

[0006] A first connecting section;

[0007] A second connecting section, the first connecting section and the second connecting section are fixedly connected or integrally formed;

[0008] A protection part, the protection part is sleeved on the first connecting section or the second connecting section;

[0009] Wherein, the first connecting section is connected to the drill pipe, and the second connecting section is connected to the taphole drill.

[0010] Optionally, the protection part is of a disc-shaped structure, the diameter of the protection part is larger than the diameter of the first connecting section, and the diameter of the protection part is larger than the diameter of the second connecting section.

[0011] Optionally, the protective part is a rectangular plate structure, and the areas of both the first connecting section and the second connecting section are smaller than the area of the protective part.

[0012] Optionally, the protective part includes a protective disc, a collecting ring and a limiting ring. The inner end of the collecting ring is fixedly connected to the protective disc. The outer diameter of the collecting ring is the same as the diameter of the protective disc.

Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components during actual implementation. The type, quantity, and proportion of each component during actual implementation can be arbitrarily changed, and the layout type of its components may also be more complex.

[0026] Please refer to Figure 1 and Figure 2 , the present utility model provides a connecting sleeve for an opening machine, including: a first connecting section 1; a second connecting section 2, the first connecting section 1 and the second connecting section 2 are fixedly connected or integrally formed; a protective part 3, the protective part 3 is sleeved on the first connecting section 1 or the second connecting section 2; wherein, the first connecting section 1 is connected to a drill pipe, and the second connecting section 2 is connected to an opening machine.

[0027] In an embodiment of the present application, specifically, the connecting sleeve includes a first connecting section 1, a second connecting section 2, and a protective part 3. The first connecting section 1 and the second connecting section 2 are connected, and are communicated with each other for transporting gas and liquid. The protective part 3 is sleeved on the first connecting section 1 or the second connecting section 2. After the first connecting section 1 is connected to the drill pipe and drilling work is carried out, nitrogen blows out the fine powder of the drilled gun mud chips in the taphole hole. The fine powder of the drilled gun mud chips is blocked by the protective part 3, preventing it from entering the gap between the connecting sleeve and the positioning ring of the opening machine, ensuring the normal operation of the opening machine, and reducing the wear of the connecting sleeve.

[0028] In an embodiment of the present application, specifically, the protective part 3 is a disc-shaped structure, the diameter of the protective part 3 is greater than the diameter of the first connecting section 1, and the diameter of the protective part 3 is greater than the diameter of the second connecting section 2.

[0029] In an embodiment of the present application, specifically, the protective part 3 is a rectangular plate structure, and the areas of both the first connecting section 1 and the second connecting section 2 are smaller than the area of the protective part 3.

[0030] Please refer to Figure 3 and Figure 4, in an embodiment of the present application, specifically, the protection part 3 includes a protection disc 301, a collection ring 302 and a limit ring 303. The protection disc 301 is fixedly connected to the inner end of the collection ring 302. The outer diameter of the collection ring 302 is the same as the diameter of the protection disc 301. The outer end of the collection ring 302 is rotatably connected to the limit ring 303. The limit ring 303 is located inside the collection ring 302. When the fine powder of the drilled stemming splashes and is blocked by the protection disc 301, the fine powder of the drilled stemming falls into the inside of the collection ring 302, and then the limit ring 303 blocks and limits the fine powder of the drilled stemming to prevent the fine powder of the drilled stemming from splashing everywhere, which saves time for collection and cleaning.

[0031] In an embodiment of the present application, specifically, a discharge groove 304 is provided on the limit ring 303. After the opener stops rotating, the limit ring 303 is rotated to make the discharge groove 304 at the lowest position, and then the fine powder of the drilled stemming is removed from the discharge groove 304 for collection, which makes it more convenient and fast to discharge the fine powder of the drilled stemming.

[0032] In an embodiment of the present application, specifically, the outer circle of the cross-section of the first connection section 1 is a hexagonal tubular structure and the inner circle is a circular tubular structure.

[0033] In an embodiment of the present application, specifically, a first connection thread for connecting a drill pipe is provided inside the first connection section 1.
