[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides a geological exploration hole expansion device, such as Figure 1 、 Figure 2 and Figure 3 As shown, the reaming device includes a mobile frame 1, a base plate 2 fixedly installed inside the mobile frame 1, a drill rod 16 arranged inside the mobile frame 1 for reaming, a moving mechanism fixedly installed on the top of the base plate 2 for moving the drill rod 16, and an installation mechanism arranged on the drill rod 16 to facilitate the installation of the drill rod 16.

[0026] The installation mechanism includes a connecting block 10, a limit block 12 fixedly installed on the connecting block 10, a bidirectional threaded rod 13 rotatably installed inside the limit block 12, a movable plate 15 sleeved on the bidirectional threaded rod 13, a plug column 14 fixedly installed on the movable plate 15, and a sleeve 11 rotatably installed inside the connecting block 10, and the drill rod 16 is inserted into the sleeve 11.

[0027] When the drill rod 16 is installed, the sleeve 11 can be first contacted with the ground, and then the two-way threaded rod 13 is rotated so that the movable plate 15 can drive the plug post 14 to move and release the sleeve 11, so that the sleeve 11 is in a rotatable state. At this time, the sleeve 11 is laid flat, which can facilitate the staff to insert the drill rod 16 into the sleeve 11. The drill rod 16 is firmly connected to the sleeve 11 through the plug rod. After the drill rod 16 is fixed, the connecting block 10 can be lifted, and the staff manually adjusts it so that the drill rod 16 and the sleeve 11 are gradually in a vertical state. At this time, the two-way threaded rod 13 is rotated so that the plug post 14 is plugged into the internal fixing sleeve 11 of the sleeve 11 to complete the installation of the drill rod 16. When replacing the drill rod 16, the two-way threaded rod 13 must be rotated first to release the fixed sleeve 11. During the process of lowering the connecting block 10 with the sleeve 11, the staff needs to slightly move the drill rod 16 until the drill rod 16 is laid flat on the ground. After the drill rod 16 is disassembled, the above installation steps are repeated to complete the replacement of the drill rod 16.

[0028] Furthermore, in order to enable the drill rod 16 to move vertically, as shown in FIG. Figure 1 and Figure 4 As shown, the moving mechanism includes a limit frame 3 fixedly mounted on the base plate 2, a slider 7 slidably mounted inside the limit frame 3, a first threaded rod 4 rotatably mounted inside the limit frame 3, a mounting frame 5 fixedly mounted on the top of the limit frame 3, and a first motor 6 fixedly mounted inside the mounting frame 5.

[0029] The mounting frame 5 is provided to improve the stability of the first motor 6 during operation. The slider 7 is inserted into the interior of the limit frame 3. The first motor 6 and the first threaded rod 4 are provided to drive the slider 7 to move vertically inside the limit frame 3. The drill rod 16 is indirectly connected to the slider 7, so the slider 7 can drive the drill rod 16 to move vertically for hole expansion.

[0030] Furthermore, in order to improve the stability of the bidirectional threaded rod 13 during operation, as Figure 2 and Figure 3 As shown, a limiting ring 17 is sleeved on the side surface of the bidirectional threaded rod 13 , and adjustment blocks 18 are fixedly connected to both ends of the bidirectional threaded rod 13 .

[0031] The setting of the limiting ring 17 enables the bidirectional threaded rod 13 to rotate stably on the two limiting blocks 12 without deviation. The setting of the adjusting block 18 is to facilitate the staff to rotate the bidirectional threaded rod 13.

[0032] In order to enable the movable plate 15 to move, Figure 2 and Figure 3 As shown, a thread groove adapted to the bidirectional threaded rod 13 is provided inside the movable plate 15 , the plug post 14 is inserted into the interior of the connecting block 10 , and a circular groove adapted to the plug post 14 is provided on the sleeve 11 .

[0033] During the rotation of the bidirectional threaded rod 13 , the engagement of the threads can force the moving plate 15 to move with the plug post 14 .

[0034] It should be noted that, in order to enable the slider 7 to move, Figure 1 and Figure 4 As shown, the first threaded rod 4 passes through the slider 7 , a threaded groove adapted to the first threaded rod 4 is provided inside the slider 7 , and the output end of the first motor 6 is fixedly connected to one end of the first threaded rod 4 .

[0035] The first motor 6 directly drives the first threaded rod 4 to rotate. When the first threaded rod 4 rotates, the slider 7 is forced to move vertically inside the limiting frame 3 through the influence of thread engagement.

[0036] Furthermore, in order to enable the drill rod 16 to rotate, as shown in FIG. Figure 1 、 Figure 2 and Figure 4 As shown, one side of the slider 7 is fixedly connected to a mounting platform 8 , and a second motor 9 is fixedly connected to the mounting platform 8 . The output end of the second motor 9 passes through the mounting platform 8 and is fixedly connected to the top of the connecting block 10 .

[0037] When reaming the hole, the drill rod 16 needs to be rotated. The drill rod 16 is inserted into the inside of the sleeve 11. The sleeve 11 is connected to the connecting block 10 and is connected to the connecting block 10 through the output end of the second motor 9. After starting the second motor 9, the second motor 9 can transmit the rotational force to the drill rod 16 through the sleeve 11 and the connecting block 10, so that the drill rod 16 can drill the ground and reame the hole.

[0038] The setting of the slider 7 is not only used to drive the drill rod 16 to move vertically for hole expansion, but also provides certain convenience for the movement of the connecting block 10, sleeve 11 and drill rod 16 when replacing and installing the drill rod 16.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
