Detailed Implementation

[0014] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0015] Please refer to the attached document. Figure 1-2 This application provides a hole reamer installation device to assist in the docking and installation between a drill rod 500 and a hole reamer. The hole reamer includes a hole reamer body and connecting shafts disposed on both sides of the hole reamer body. The end of the drill rod 500 is provided with a threaded connection hole, and the connecting shaft is provided with a threaded connection end. The threaded connection end is used to screw into the threaded connection hole to realize the docking between the drill rod 500 and the connecting shaft.

[0016] The reamer mounting device includes a connecting sleeve 100 and a rotating member 200. The connecting sleeve 100 is fitted onto the outer periphery of a drill rod 500, specifically onto the outer periphery of the end of the drill rod 500 used for connection with the reamer. The rotating member 200 is disposed on one axial side of the connecting sleeve 100, and the rotating member 200 is provided with a clamping structure 300 forming a clamping cavity for clamping the reamer. The clamping structure 300 is movably disposed along the axial direction of the clamping cavity, wherein there are two clamping cavities, each used to accommodate two connecting shafts of the reamer. The rotating member 200 is rotatably disposed to switch between a first position and a second position, wherein the rotating member 200 has a first rotation direction and a second rotation direction. When moving from the first position to the second position, the rotating member 200 rotates along the first rotation direction, and when moving from the second position to the first position, the rotating member 200 rotates along the second rotation direction. The first rotation direction can be clockwise and the second rotation direction can be counterclockwise. In the first position, the moving direction of the clamping structure 300 is parallel to the axial direction of the connecting sleeve 100, and the clamping cavity and the connecting sleeve 100 are coaxially arranged. At this time, the threaded connection end of the reamer installed on the clamping structure 300 is aligned with the threaded connection hole in the drill rod 500 installed in the connecting sleeve 100. In the second position, there is an angle between the axis of the clamping cavity and the axis of the connecting sleeve 100. This angle can be reasonably set according to actual needs, for example, but not limited to, the angle being equal to the tilt angle of the drill rod 500 relative to the ground, so that the axis of the clamping cavity is parallel to the horizontal direction when the rotating member 200 is in the second position, thereby facilitating the convenient installation of the reamer on the clamping structure 300.

[0017] In use, first install the connecting sleeve 100 onto the drill rod 500, then install the reamer onto the clamping structure 300. Next, rotate the rotating component 200 from the second position to the first position. During rotation, the clamping structure 300 is slowly lowered under manual pulling until the threaded connection end aligns with the threaded connection hole. Then, rotate the reamer to achieve a threaded connection between the reamer and the drill rod 500. This installation device eliminates the need for manual lifting of the reamer and alignment with the drill rod 500, reducing the installation difficulty and preventing the reamer from falling during installation, thus improving worker safety.

[0018] In this embodiment, the reamer can be installed on the drill rod 500 with the assistance of the above-mentioned installation device. This not only eliminates the need for manual alignment of the drill rod 500 and the reamer, reducing the installation difficulty of the reamer, but also prevents the reamer from falling off during installation, thus improving the safety of the workers.

[0019] In some embodiments of this application, to facilitate the assembly and disassembly of the connecting sleeve 100 on the drill pipe 500, the connecting sleeve 100 is a split-connection structure. Specifically, the connecting sleeve 100 includes a first half-sleeve 110 and a second half-sleeve 120, which are fixedly connected by a bolt assembly to fix the connecting sleeve 100 to the outer periphery of the drill pipe 500. The second half-sleeve 120 has an extension 130 on the side away from the first half-sleeve 110, and the rotating member 200 is a rotating plate, which is hinged to the extension 130.

[0020] In some embodiments of this application, the connecting sleeve 100 is provided with an anti-rotation surface 131, and the rotating member 200 is provided with an anti-rotation mating surface 201. In the first position, the anti-rotation surface 131 and the anti-rotation mating surface 201 are in anti-rotation engagement to restrict the rotating member 200 from continuing to rotate in the second rotation direction, ensuring that the rotating member 200 accurately rotates to the second position. Optionally, the end face of the rotating plate near the extension 130 forms the anti-rotation mating surface 201, and the end of the extension 130 near the rotating plate is provided with the anti-rotation surface 131.

[0021] In some embodiments of this application, the clamping structure 300 includes a connecting seat 310 and two clamps 320. The two clamps 320 are spaced apart on the connecting seat 310 along the moving direction of the clamping structure 300. The connecting seat 310 and the rotating member 200 are in sliding engagement, and each clamp 320 forms a clamping cavity. By clamping the two connecting shafts with the two clamps 320 respectively, the hole expander is pre-fixed on the clamping structure 300, preventing the hole expander from falling off during installation and improving the safety of the operator.

[0022] In some embodiments of this application, the clamp 320 includes a first clamping block 321 and a second clamping block 322 disposed opposite to each other, wherein the first clamping block 321 and the second clamping block 322 are detachably fixedly connected, and the first clamping block 321 is disposed on the connecting seat 310. The connection between the first clamping block 321 and the second clamping block 322 is preferably screwed.

[0023] Optionally, a sliding assembly (with attachment) is provided between the connecting seat 310 and the rotating member 200. Figure 1-2 (Not shown in the image), the sliding assembly includes a slide rail and a slider, which are respectively disposed on the connecting seat 310 and the rotating part 200.

[0024] In some embodiments of this application, the first position and the second position are arranged along the first rotation direction of the rotating member 200. The hole expander mounting device also includes a connecting rod 410, the two ends of which are movably connected to the connecting sleeve 100 and the rotating member 200, respectively, so as to restrict the rotating member 200 in the second position from rotating along the first rotation direction, so that the rotating member 200 in the second position can better support the hole expander.
