Description

Technical Field

[0001] This utility model relates to the field of roller cone drill bit technology, specifically a roller cone micro-reamer. Background Technology

[0002] Single-cone drill bits are used for oil well exploration and logging. They feature diamond composite teeth at the tip. As a tool for drilling rock formations, single-cone drill bits have been widely used. Significant improvements in drill bit performance have directly reduced drilling costs, especially in the last decade. Service life and drilling speed are two key performance indicators that ultimately determine the extent to which a drill bit affects drilling costs. However, existing single-cone drill bits still encounter some problems in practical use.

[0003] For example, application number CN201820004425.3 discloses a single roller cone drill bit, including a drill body and a spherical roller cone. The drill body is connected to the roller cone through a journal at its lower end. The tooth surface of the spherical roller cone includes a first tooth surface and a second tooth surface from top to bottom. Both the first tooth surface and the second tooth surface are provided with cutting teeth. The cutting teeth include wedge-shaped cutting teeth and conical spherical cutting teeth. The wedge-shaped cutting teeth and the conical spherical cutting teeth are respectively embedded in the first tooth surface and the second tooth surface. This has the characteristic of improving the stability of the drill bit during the drilling process. Existing roller cone drill bits are often installed by bolts and nuts. When the roller cone drill bit malfunctions and needs to be repaired or replaced, it is often inconvenient to operate, which greatly affects the use effect.

[0004] To address the aforementioned problems, a roller cone micro-reamer bit is proposed. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0030] Combination Figures 1-3 A roller cone micro-reamer includes a connecting cylinder 1, a connecting plate 11 detachably mounted on the bottom of the connecting cylinder 1, multiple sets of connecting plates 11, and a disassembly mechanism for replacing damaged connecting plates 11. The disassembly mechanism includes an installation groove 12 formed at the bottom of the connecting cylinder 1, a connecting block 13 fixedly connected to one side of the connecting plate 11, a knob 131 mounted on one side of the connecting block 13, a water tank 14 fixedly connected inside the connecting cylinder 1, and an installation block 15 also fixedly connected inside the connecting cylinder 1.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the problem that existing roller cone drill bits are typically installed using bolts and nuts, which is inconvenient for repair or replacement when the bit malfunctions, significantly impacting performance, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, a drill bit body 111 is rotatably connected to one side of the connecting plate 11. A fixing groove 121 is provided inside the mounting groove 12. A locking block assembly 132 is fixedly connected to one side of the knob 131. The locking block assembly 132 is slidably engaged with the connecting block 13. A spring rod 133 is rotatably connected inside the connecting plate 11. One end of the spring rod 133 is fixedly connected to the knob 131. A threaded rod 134 is rotatably connected inside the connecting plate 11. The threaded rod 134 is fixedly connected to the spring rod 133. A sliding block 135 is threadedly connected to the threaded rod 134. The sliding block 135 is slidably connected inside the connecting plate 11. A fixing block 136 is fixedly connected to the bottom of the sliding block 135. The fixing block 136 is slidably engaged with the fixing groove 121. During use, the connecting cylinder 1 can be installed in a designated position and put into operation. The drill bit body 111 allows the connecting cylinder 1 to drill holes in the ground. When the drill bit body 111 on a set of connecting plates 11 is damaged, it can be... Pulling knob 131 causes the locking block assembly 132 to move out of the connecting block 13. Knob 131 can then be rotated normally. Knob 131, via spring rod 133, drives threaded rod 134 to rotate, causing sliding block 135 to move. Sliding block 135 then drives fixed block 136 to move, causing fixed block 136 to disengage from the fixing groove 121. Connecting plate 11 can then be removed from the mounting groove 12. When connecting plate 11 needs to be installed, align it with the mounting groove 12 and insert it. Then pull knob 131 and rotate it in the opposite direction to install the connecting plate 11. In normal operation, spring rod 133 can reset knob 131, causing the locking block assembly 132 to move into the connecting block 13. This prevents the connecting plate 11 from falling off during use due to knob 131 rotation, enabling workers to quickly replace damaged drill bit bodies 111 and improving work efficiency.

[0034] Example 2:

[0035] To address the problem that existing roller cone drill bits often lack dust suppression equipment, leading to excessive dust accumulation during use and hindering normal work, this embodiment discloses the following technical solution, specifically as follows: Figure 1 and Figure 5As shown, a water inlet pipe 141 is fixedly connected to the top of the connecting cylinder 1, and the water inlet pipe 141 is fixedly connected to the water storage tank 14. A solenoid valve 142 is fixedly connected to the bottom of the water storage tank 14, and a water outlet pipe 143 is fixedly connected to one end of the solenoid valve 142. Multiple sets of the mounting block 15 and the water outlet pipe 143 are provided. The water outlet pipe 143 is located inside the mounting block 15. When the connecting cylinder 1 is needed, water can be injected into the water storage tank 14 through the water inlet pipe 141. When the work starts, the solenoid valve 142 is activated, and the solenoid valve 142 sprays the water inside the water storage tank 14 out through the water outlet pipe 143. Thus, water spraying can be performed during the operation of the connecting cylinder 1 to prevent dust from flying, thereby achieving the function of dust suppression on the ground during the operation and improving the efficiency of use.
