DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 and Figure 3As shown, in the present embodiment, a drilling rig hole expansion drill bit device comprises a mounting frame 1, characterized in that: an adjusting assembly 7 is installed outside the mounting frame 1, the adjusting assembly 7 comprises a mounting plate 701 fixedly connected to the bottom of the outer wall on one side of the mounting frame 1, a screw rod 702 is threadedly connected to the middle of the mounting plate 701, a connecting block 704 is rotatably connected to the bottom of the screw rod 702, a plurality of limit rods 703 are fixedly connected to the outer wall at the top of the connecting block 704, the plurality of limit rods 703 are all slidably inserted in the mounting plate 701, and a mounting disk 705 is rotatably connected to the center of the outer wall at the bottom of the connecting block 704.

[0024] A motor 2 is fixedly installed inside the installation frame 1, and an output shaft 3 is coaxially fixed to the rotating shaft of the motor 2. One end of the bottom of the output shaft 3 is set as a diamond-shaped tip. A drill body 6 is installed in each of the multiple holes in the installation disk 705, and the tops of the multiple drill bodies 6 are all provided with a clamping hole that is compatible with the diamond-shaped tip.

[0025] If it is necessary to replace the drill body 6 of other models, rotate the turntable on the top of the screw rod 702, and the connecting block 704 restricted by the limit rod 703 will also be driven downward by the screw rod 702, and then the output shaft 3 will also be disengaged from the clamping hole of the drill body 6. Then, move the mounting plate 705 to make it rotate at the bottom of the connecting block 704, so that the corresponding drill body 6 is under the output shaft 3, and then drive the screw rod 702 to make the drill body 6 enter the clamping hole of the corresponding drill body 6 again, and the replacement work can be completed.

[0026] like Figure 2 As shown, a mounting sleeve 4 is rotatably connected to each of the multiple holes of the mounting disk 705, two vertically arranged limit grooves 5 are provided inside each of the multiple mounting sleeves 4, a plurality of drill bit bodies 6 are respectively slidably connected to two adjacent limit grooves 5, a spring 9 is fixedly connected to the inner wall of the top of the multiple limit grooves 5, and two adjacent springs 9 are respectively fixedly connected to the top of the sliders of the multiple drill bit bodies 6.

[0027] A stabilizing rod 10 is fixedly connected to each of the plurality of limit grooves 5, and the plurality of stabilizing rods 10 are respectively located in the plurality of springs 9, and the slide blocks of the plurality of drill bodies 6 are respectively slidably mounted on the outside of the plurality of stabilizing rods 10, so that the state of the drill body 6 is more stable.

[0028] When the mounting plate 705 moves downward, except for the drill body 6 blocked by the output shaft 3 and unable to move, the other drill bodies 6 will overcome the thrust of the spring 9 and move upward along the limiting groove 5 under the obstruction of the plate, thereby ensuring that these drill bodies 6 will not hinder the progress of the hole expansion work.

[0029] like Figure 1 and Figure 4As shown, a positioning assembly 8 is installed on the outside of the connecting block 704, and the positioning assembly 8 includes an extension plate 801 fixedly connected to the top of the circumferential outer wall of the connecting block 704, a sliding rod 802 is slidably inserted at one end of the extension plate 801, a positioning head 803 is fixedly connected to the bottom end of the sliding rod 802, a spring 805 is sleeved on the outside of the sliding rod 802, and a plurality of positioning holes 804 distributed at equal distances are opened on the top outer wall of the mounting plate 705, and the positioning head 803 can enter into the plurality of positioning holes 804.

[0030] While the mounting disk 705 is rotating, the mounting disk 705 can squeeze the positioning head 803, and then overcome the thrust of the spring 2 805 to detach from the positioning hole 804. When the positioning head 803 moves to the top of the positioning hole 804, the spring 2 805 recovers to drive the positioning head 803 to enter the corresponding positioning hole 804 again, thereby making the adjustment process sufficiently accurate.

[0031] like Figure 1 As shown, the thread lead angle of the thread groove of the screw rod 702 is smaller than the equivalent friction angle, so that it has a self-locking property, thereby ensuring that the position of the connecting block 704 will not change arbitrarily.

[0033] If it is necessary to replace the drill body 6 of another type, the turntable on the top of the screw rod 702 is rotated, and the connecting block 704 restricted by the limit rod 703 will also be driven downward by the screw rod 702, and then the output shaft 3 will also be separated from the clamping hole of the drill body 6, and then the mounting plate 705 is turned to make it rotate at the bottom of the connecting block 704, so that the corresponding drill body 6 is under the output shaft 3, and then the screw rod 702 is driven to make the drill body 6 enter the clamping hole of the corresponding drill body 6 again, and the replacement work is completed. While the mounting plate 705 is rotating, the mounting plate 705 can The positioning head 803 is squeezed, and then overcomes the thrust of spring 2 805 to break away from the positioning hole 804. When the positioning head 803 moves to the top of the positioning hole 804, the spring 2 805 is restored to drive the positioning head 803 to enter the corresponding positioning hole 804 again, so that the adjustment process is accurate enough. When the mounting plate 705 moves downward, except for the drill body 6 blocked by the output shaft 3 and unable to move, the other drill bodies 6 will overcome the thrust of spring 1 9 and move upward along the limit groove 5 under the obstruction of the plate, thereby ensuring that these drill bodies 6 will not hinder the expansion work.
