[0023] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] Embodiment:

[0025] As Figure 1 and Figure 2 shown, a pipe drilling device includes:

[0026] Working box 19;

[0027] Backing plate 29, which is fixedly arranged at one end of the working box 19;

[0028] Load-carrying plate 22, which is arranged to lift and slide at one end of the working box 19, and the load-carrying plate 22 is opposite to the backing plate 29 up and down;

[0029] Working motor 23, which is fixedly arranged at one end of the load-carrying plate 22 close to the backing plate 29;

[0030] Drill bit 24, which is fixedly installed at the output end of the working motor 23;

[0031] First connecting rod 36, which is arranged to be adjustable in lifting and sliding at one end of the working box 19;

[0032] Limit block 11, which is fixedly arranged at one end of the first connecting rod 36, and the limit block 11 is arranged under the load-carrying plate 22;

[0033] Place the pipe to be drilled on the backing plate 29, fix the pipe, and according to the depth of the hole to be drilled, drive the limit block 11 to move through the first connecting rod 36, so that the limit block 11 moves to a certain position. Start the working motor 23, the working motor 23 drives the drill bit 24 to rotate, move the carrier plate 22, and the carrier plate 22 drives the drill bit 24 to move closer to the pipe through the working motor 23. The drill bit 24 drills the pipe. When the carrier plate 22 abuts against the limit block 11, the drill bit 24 cannot move further. By using the method of abutting the limit block 11 against the carrier plate 22, the stroke of the drill bit 24 is restricted, so that the drill bit 24 will not move too far and damage the pipe.

[0034] As Figure 1 shown, the backing plate 29 is provided with a drilling groove 30 that penetrates up and down, and the drilling groove 30 is opposite to the drill bit 24 up and down. When it is necessary to drill through the pipe, the drill bit 24 can extend into the drilling groove 30.

[0035] As Figure 1 shown, two pressing plates 27 are placed on the backing plate 29. Each pressing plate 27 is provided with two first screws 26 with nuts. The first screw 26 passes through the pressing plate 27 and is threadedly connected to the backing plate 29. A gasket 28 is placed between the nut of the first screw 26 and the pressing plate 27. When it is necessary to drill the pipe, screw out the first screw 26, place the pipe between the backing plate 29 and the two pressing plates 27, and then screw in the first screw 26 so that the half point 29 and the pressing plate 27 fix the pipe. By setting the number of gaskets 28 between the nut of the first screw 26 and the pressing plate 27, the first screw 26 can better fix the pressing plate 27.

[0036] As Figure 1 shown, a vertical sliding groove 20 is opened in the inner wall on one side of the working box 19. A transmission block 16 is slidably arranged in the sliding groove 20 along the length direction of the sliding groove 20. A second connecting rod 21 is fixedly arranged between the transmission block 16 and the carrier plate 22. A hydraulic rod 10 is connected between the transmission block 16 and the sliding groove 20. When the transmission block 16 is not affected by an external force, the hydraulic rod 10 pushes the transmission block 16 to move upward.

[0037] As Figure 1 、 Figure 2 and Figure 3As shown, a working cavity 18 is formed in the inner wall of one side of the sliding groove 20. A transmission rack 17 is fixedly arranged at one end of the transmission block 16 close to the working cavity 18. A first stress shaft 14 is rotatably arranged in the working cavity 18. A first transmission gear 15 and a second transmission gear 39 are fixedly arranged on the first stress shaft 14. The first transmission gear 15 meshes with the transmission rack 17. A second stress shaft 13 is rotatably arranged in the working cavity 18. A third transmission gear 12 is fixedly arranged on a section of the second stress shaft 13 in the working cavity 18. The third transmission gear 12 meshes with the second transmission gear 39. The diameter of the third transmission gear 12 is larger than that of the second transmission gear 39. An annular block 32 is fixedly arranged at one end of the second stress shaft 13 extending out of the working cavity 18. Stress rods 31 are evenly arranged in a circumferential manner on the outer periphery of the annular block 32. The user drives the annular block 32 to rotate through the stress rods 31, and the annular block 32 drives the second stress shaft 13 to rotate.

[0038] As Figure 2 shown, a vertical adjustment groove 33 is formed at one end of the working box 19. A load-carrying block 37 is slidably arranged in the adjustment groove 33 along the length direction of the adjustment groove 33. A first connecting rod 36 is fixedly arranged at one end of the load-carrying block 37 facing away from the working box 19. A second screw rod 34 with a nut passes through the first connecting rod 36 and abuts against the load-carrying block 37 and the inner wall of the adjustment groove 33. By screwing out the second screw rod 34, the position of the load-carrying block 37 in the adjustment groove 33 can be adjusted.

[0039] As Figure 2 shown, a scale 35 is arranged at one end of the working box 19. The scale 35 is arranged on one side of the adjustment groove 33. When the upper end surface of the load-carrying block 37 is aligned with the zero scale line of the scale 35, the bottom end of the drill bit 14 and the top end of the backing plate 29 are at the same horizontal plane. The zero scale line is at the middle position of the scale 35.

[0040] Working principle:

[0041] When it is necessary to drill the pipe, screw out the first screw rod 26. After placing the pipe between the backing plate 29 and the pressing plate 27, screw in the first screw rod 26 so that the pressing plate 27 and the backing plate 29 fix the pipe. Adjust the number of gaskets 28 according to actual requirements. Screw out the second screw rod 34. According to the depth of the hole to be drilled, adjust the position of the load-carrying block 37 in the adjustment groove 33. After the adjustment is completed, screw in the second screw rod 34. The load-carrying block 37 drives the limit block 11 to move through the first connecting rod 36. Start the working motor 23. The working motor 23 drives the drill bit 24 to rotate, drives the through-ring block 32 to rotate through the force-bearing rod 31. The through-ring block 32 drives the second force-bearing shaft 13 to rotate. The second force-bearing shaft 13 drives the third transmission gear 12 to rotate. The third transmission gear 12 meshes with and drives the second transmission gear 39 to rotate. The second transmission gear 39 drives the first transmission gear 15 to rotate through the first force-bearing shaft 14. The first transmission gear 15 meshes with and drives the transmission rack 17 to move. The transmission rack 17 drives the load-carrying plate 22 to move through the second connecting rod 21. The load-carrying plate 22 drives the drill bit 24 to move through the working motor 23. The drill bit 24 moves to drill the pipe. After the load-carrying plate 22 moves a certain distance and abuts against the limit block 11, loosen the force-bearing rod 31, and the hydraulic rod 10 pushes the transmission block 16 to move upward.
