Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a drilling device. Background Art

[0002] In underground drilling construction in coal mines, in the absence of measurement technology to control the drilling trajectory offset, when the construction drilling trajectory deviates from the drilling design trajectory, the drilling trajectory deviation becomes larger and larger due to the inability to correct it in time.

[0003] When vertical drilling is performed on the ground, the drill bit will tilt and deviate in the vertical direction during the drilling process, causing the offset to gradually increase during the subsequent drilling process. This causes the drilling trajectory of the drill bit to not coincide with the preset trajectory, and therefore cannot meet the construction requirements. Secondary drilling is often required, which seriously affects the construction progress.

[0004] Therefore, there is a need for a drilling device that can solve the problem of the trajectory deviating from the preset trajectory during the drilling process. Utility Model Content

[0005] The utility model provides a drilling device to solve the problem of trajectory deviation of drilling holes in the prior art.

The steering unit adjusts the forward direction of the drill bit according to the detection result of the detection unit. With this solution, the drill bit is used for drilling holes, and the drill rod is connected to the drill bit by driving. During the drilling process, the detection unit detects the drilling trajectory of the drill bit. When the drilling trajectory of the drill bit deviates from the preset trajectory, the steering unit adjusts the drilling direction of the drill bit according to the detection result of the detection unit, and corrects the trajectory of the drill bit to solve the problem of trajectory deviation during the drilling process.

In this way, the plurality of telescopic rods are arranged along the circumference of the drill bit, and when the drill bit needs to be turned, the plurality of telescopic rods are extended or shortened respectively, so that the drill bit turns under the action of the telescopic rods and returns to the predetermined trajectory of the drill bit, thereby solving the problem of deviation of the drill bit during drilling. The universal joint is arranged between the drill bit and the telescopic rod, so that the telescopic rod can rotate relative to the drill bit during the process of extension and shortening.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, an embodiment of the utility model provides a drilling equipment, including: a drill rod 10, a drill bit 20, a detection unit 30 and a steering unit 40, wherein the detection unit 30 is arranged on the drill bit 20, and the detection unit 30 is used to detect the forward trajectory of the drill bit 20; one end of the steering unit 40 is connected to the drill rod 10, and the other end of the steering unit 40 is connected to the drill bit 20, and the steering unit 40 adjusts the forward direction of the drill bit 20 according to the detection result of the detection unit 30.

[0029] With this solution, the drill bit 20 is used for drilling, and the drill rod 10 is drivingly connected to the drill bit 20. During the drilling process, the detection unit 30 detects the drilling trajectory of the drill bit 20. When the drilling trajectory of the drill bit 20 deviates from the preset trajectory, the steering unit 40 adjusts the drilling direction of the drill bit 20 according to the detection result of the detection unit 30, and corrects the trajectory of the drill bit 20 to solve the problem of trajectory deviation during drilling.

[0030] like Figure 1 As shown, the steering part 40 includes a plurality of telescopic rods 41 and a plurality of universal joints 42, one end of the telescopic rod 41 is connected to the universal joint 42, the other end of the telescopic rod 41 is connected to the drill rod 10, and the end of the universal joint 42 facing away from the drill rod 10 is connected to the drill bit 20, and the plurality of telescopic rods 41 are arranged along the circumference of the drill bit 20, and the plurality of telescopic rods 41 can be extended and retracted respectively to control the direction of the drill bit 20.

[0031] In this configuration, multiple telescopic rods 41 are arranged along the circumference of the drill bit 20. When the drill bit 20 needs to turn, the multiple telescopic rods 41 are extended or shortened respectively, so that the drill bit 20 turns under the force of the telescopic rods 41 and returns to the predetermined track of the drill bit 20, thereby solving the problem of deviation of the drill bit 20 during drilling. The universal joint 42 is arranged between the drill bit 20 and the telescopic rod 41, so that the telescopic rod 41 can rotate relative to the drill bit 20 during the process of extension and shortening. In a specific embodiment of the utility model, the telescopic rod 41 is an electric telescopic rod.

The side of the connecting plate 43 facing away from the connecting shaft 44 is connected to the universal joint 42 . The other end of the connecting shaft 44 is connected to the drill bit 20 .

[0033] In this arrangement, the connecting plate 43 is fixedly connected to the connecting shaft 44, and the other end of the connecting shaft 44 is fixedly connected to the drill bit 20. When controlling the steering of the drill bit 20, the telescopic rod 41 pushes the connecting plate 43, causing the connecting plate 43 to deflect at an angle, and the connecting plate 43 drives the drill bit 20 to deflect through the connecting shaft 44.

[0037] In this way, a plurality of elastic structures 46 are arranged between the protective shell 45 and the drill bit 20, and the elastic structures 46 make the travel directions of the drill rod 10 and the drill bit 20 consistent. When the drill bit 20 turns, the elastic structure 46 stretches or compresses, and when the turning is completed, the elastic structure 46 rebounds, so that the drill rod 10 and the drill bit 20 return to the same travel direction.

[0038] like Figure 1 As shown, the elastic structure 46 includes a first connecting member 461, a second connecting member 462 and an elastic pressure ring 463.

One end of the second connecting member 462 is connected to the drill bit 20, and the other end of the second connecting member 462 is connected to the elastic pressure ring 463.

[0039] In this way, the first connecting member 461 is arranged between the protective shell 45 and the elastic pressure ring 463, and the second connecting member 462 is arranged between the drill bit 20 and the elastic pressure ring 463. The first connecting member 461 and the second connecting member 462 transmit external tension and pressure to the elastic pressure ring 463, so that the elastic pressure ring 463 undergoes elastic deformation.

[0040] like Figure 1 As shown, the drilling equipment further includes a bellows 50 , one end of the bellows 50 is connected to the protective shell 45 , and the other end of the bellows 50 is connected to the drill bit 20 . The bellows 50 is used to protect the elastic structure 46 .

The bellows 50 is elastic and can be deformed adaptively with the movement of the drill bit 20 during the turning process of the drill bit 20, and is not easily damaged.

[0042] In a specific embodiment of the present invention, the detection unit 30 includes a three-axis gyroscope, which is disposed in the drill bit 20 and is used to detect the forward trajectory of the drill bit 20 .

[0043] With such arrangement, the three-axis gyroscope detects the travel trajectory of the drill bit 20 , which is convenient for comparison with a preset trajectory, thereby correcting the travel direction of the drill bit 20 .
