[0002] Mining equipment mainly refers to the general term for various specialized equipment used in the production process of coal, ferrous metals, and non-ferrous metals mines, including mining, screening, transportation, and other equipment. A mine refers to an independent production and operation unit that extracts ore within a certain mining boundary. A mine mainly includes one or more mining workshops (or pitheads, mine shafts, open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants). Drill rods are used to connect the surface equipment of the drilling rig to the drilling equipment or bottom hole device located at the bottom of the well. The purpose of the drill rod is to transport drilling mud to the drill bit and to raise, lower, or rotate the bottom hole device together with the drill bit. Drill rods must be able to withstand huge internal and external pressure, torsion, bending, and vibration.

[0003] Currently available drill pipes for mining equipment cannot control the exposed surface of the drill pipe body during use, causing the cutting teeth of the drill pipe body to come into contact with the mineral prematurely, thereby reducing its service life. Therefore, there is an urgent need for a new type of drill pipe for mining equipment to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a drill rod for mining equipment to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0027] Example 1

[0028] Reference Figures 1 to 4 This utility model discloses a drill rod for mining equipment, including a drill rod body 1, a protective sleeve 2 on the outside of the drill rod body 1, a connecting sleeve 3 on the outside of the protective sleeve 2, an electric push rod 4 inside the connecting sleeve 3, a locking block 5 and a fixing ring 6 on the outside of the connecting sleeve 3, a locking groove 7 and a through hole 8 inside the fixing ring 6, a fixing bolt 9 inside the through hole 8, a positioning cylinder 10 and a positioning rod 11 inside the fixing ring 6, a connecting frame 12 on the outside of the positioning cylinder 10, and a limit hole 13 inside the connecting frame 12. In this embodiment, the drill rod body 1 serves to break minerals, and the protective sleeve 2 serves to protect the drill rod body 1.

[0029] Reference Figure 1 The drill pipe body 1 is slidably connected to the protective sleeve 2, and the protective sleeve 2 is slidably connected to the inside of the connecting cylinder 3. In this embodiment, the connecting cylinder 3 serves to house the protective sleeve 2.

[0030] Reference Figure 2 and Figure 3The locking block 5 is fixedly connected to the bottom of the connecting cylinder 3, the electric push rod 4 is fixedly connected to the inside of the connecting cylinder 3, the locking groove 7 is adapted to the locking block 5. In this embodiment, the locking block 5 plays a limiting role, the locking groove 7 plays a role in locking the locking block 5, and the electric push rod 4 plays a role in driving the protective sleeve 2 to slide.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The fixing ring 6 is snapped onto the outside of the connecting cylinder 3 and the connecting frame 12. The connecting frame 12 is fixedly connected to the drill rod body 1. In this embodiment, the fixing ring 6 serves to fix the connecting frame 12 and the connecting cylinder 3, and the connecting frame 12 serves to facilitate the snapping of the fixing ring 6.

[0032] Reference Figure 3 The fixing bolt 9 is engaged inside the through hole 8. The positioning cylinder 10 and the positioning rod 11 are both fixedly connected to one side of the fixing ring 6. In this embodiment, the through hole 8 serves to install the fixing bolt 9, and the fixing bolt 9 serves to prevent the fixing ring 6 from loosening.

[0033] Reference Figure 4 The positioning rod 11 is slidably connected to the inside of the positioning cylinder 10, and the limiting hole 13 is adapted to the positioning cylinder 10. In this embodiment, the positioning rod 11 serves to connect the positioning cylinder 10, the positioning cylinder 10 serves to engage the connecting frame 12, and the limiting hole 13 serves to engage the positioning cylinder 10.

[0034] The implementation principle of this embodiment is as follows:

[0035] During use, the fixing ring 6 is engaged with the mining equipment. By rotating the fixing ring 6, the drill rod body 1 is rotated.

[0036] When it is necessary to change the exposed length of the drill pipe body 1, the electric actuator 4 starts working and drives the protective sleeve 2 to slide on the outside of the drill pipe body 1. When the output shaft of the electric actuator 4 retracts, the electric actuator 4 will drive the protective sleeve 2 to slide into the connecting cylinder 3 to increase the exposed length of the drill pipe body 1. When it is necessary to reduce the exposed length of the drill pipe body 1, the output shaft of the electric actuator 4 starts to extend outward and pushes the protective sleeve 2 out of the connecting cylinder 3. As the protective sleeve 2 slides out of the connecting cylinder 3, the exposed length of the drill pipe body 1 will gradually shorten until the required length is reached. Then the electric actuator 4 will stop working, so that the protective sleeve 2 stays in the current position to wrap the drill pipe body 1 and prevent the cutting teeth of the drill pipe body 1 from having too much contact with the mineral or premature contact.

[0037] The electric actuator 4 is a mature existing structure that can enable multiple electric actuators 4 to operate synchronously, and the hovering function is one of the basic functions of the electric actuator 4;

[0038] When the drill rod body 1 reaches the end of its service life and needs to be replaced, it needs to be removed from the mining equipment along with the fixing ring 6. After removing the drill rod body 1 and the fixing ring 6, the fixing bolt 9 needs to be removed from the inside of the through hole 8, and then the fixing ring 6 (the fixing ring 6 is made of semi-circular rings spliced ​​together, which facilitates disassembly and assembly) needs to be pulled to both sides. During the process of pulling the fixing ring 6 to both sides, the positioning rod 11 will slide inside the positioning cylinder 10, and the positioning cylinder 10 will slide inside the limiting hole 13. At the same time, the slot 7 will slide outside the locking block 5. When the positioning rod 11 is pulled out from the inside of the positioning cylinder 10, and the positioning cylinder 10 is also pulled out from the inside of the limiting hole 13, the slot 7 and the locking block 5 are separated. Then, the drill rod body 1 that needs to be replaced can be pulled out from the inside of the connecting cylinder 3 and the protective sleeve 2, and the unused drill rod body 1 can be inserted into the inside of the connecting cylinder 3 and the protective sleeve 2.

[0039] After replacing the drill rod body 1, during the splicing of the fixing ring 6, the top of the connecting cylinder 3 needs to be in contact with the connecting frame 12, and the positioning cylinder 10 and the limiting hole 13 need to be concentric. Then, push the fixing ring 6 so that the positioning cylinder 10 is inserted into the limiting hole 13. At the same time, it is necessary to ensure that the slot 7 is parallel to the edge of the block 5. After the positioning cylinder 10 is fully inserted into the limiting hole 13, the slot 7 will engage with the outside of the block 5. Then, install the other half of the fixing ring 6. During the splicing of the fixing rings 6, the positioning cylinder 10 and the positioning rod 11 need to be concentric to quickly complete the splicing of the fixing ring 6. After the fixing ring 6 is spliced, install the fixing bolt 9 into the through hole 8 and use a tool to tighten the fixing bolt 9. At this point, the replacement of the drill rod body 1 is complete.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] The connecting sleeve 3 and the electric push rod 4 work together to drive the protective sleeve 2 to slide. The protective sleeve 2 wraps around the drill rod body 1. The through hole 8 and the fixing bolt 9 work together to connect the fixing ring 6. The positioning sleeve 10 and the positioning rod 11 work together to facilitate the connection of the fixing ring 6. The positioning sleeve 10 and the limiting hole 13 work together to engage the connecting frame 12. The slot 7 and the locking block 5 work together to engage the connecting sleeve 3. The fixing ring 6 connects the drill rod body 1 and the connecting frame 12. By using the above structure, the protective sleeve 2 can wrap around the electric push rod 4, thereby preventing its cutting teeth from contacting the mineral prematurely and ensuring its service life.

[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
