[0024] As shown in Figures 1-4 A mining anchor rod mounting device, comprising a hole 1, an anchor rod body 2, an annular base 3, a threaded column 4, an adjusting assembly 5, an adjusting ring 6, a ball 7, a connecting column 8, a positioning assembly 9, a handle 10 and an I-shaped moving wheel 11 and the like. The device realizes accurate adjustment of the height and angle of the adjusting ring 6 through the adjusting assembly 5, so as to ensure that the anchor rod body 2 can be accurately inserted into the hole 1, effectively improving the efficiency and quality of anchor rod installation.

[0025] Specifically, the upper surface of the annular base 3 is connected with the threaded column 4, the threaded column 4 is provided with the adjusting assembly 5, one side of the adjusting assembly 5 is connected with the adjusting ring 6, the adjusting assembly 5 is used for adjusting the height and angle of the adjusting ring 6, the inside of the adjusting ring 6 is connected with the connecting column 8, the bottom end of the connecting column 8 is connected with the positioning assembly 9, the positioning assembly 9 comprises a positioning barrel 91, the positioning barrel 91 comprises an upper barrel body 911 and a lower barrel body 912, the outer diameter of the lower barrel body 912 matches the diameter of the hole 1, so that the lower barrel body 912 can be accurately inserted into the hole 1, playing a role of calibration positioning. The lower surface of the upper barrel body 911 is provided with a threaded groove one 913 and a threaded groove two 914 from inside to outside, the top end of the lower barrel body 912 is connected with an annular threaded head 915, the annular threaded head 915 is threadedly connected with the threaded groove two 914, and the threaded groove one 913 is used for threadedly connecting with the top end of the anchor rod body 2.

[0026] In use, first, the lower cylinder 912 is aligned and inserted into the hole 1 by vertical downward movement, and the position of the alignment cylinder 91 is calibrated through the hole 1, so that the alignment cylinder 91 is on the same axis as the hole 1. Then, the lower cylinder 912 that has been aligned with the hole 1 is moved out of the hole 1 by vertical upward movement, and the lower cylinder 912 is disassembled. Subsequently, the upper cylinder 911 is offset from the hole 1 by angle adjustment, facilitating the rotation of the top end of the anchor rod body 2 into the threaded groove one 913 at the bottom of the upper cylinder 911. Then, the upper cylinder 911 is rotated to align with the hole 1, and the anchor rod body 2 is inserted into the hole 1 to the appropriate position by vertical downward movement. In this way, the anchor rod body 2 is positioned by the upper cylinder 911, and the anchor rod body 2 is coaxially distributed with the alignment cylinder 91, ensuring that the anchor rod body 2 is at the center of the hole 1, avoiding the influence of anchor rod insertion position deviation on anchoring effect. At the same time, the length of the anchor rod body 2 inserted into the hole 1 is controlled by the lifting of the upper cylinder 911, facilitating the accurate control of the anchor rod insertion depth.

[0027] In addition, the anchor rod body 2 and the upper cylinder 911 are connected in a threaded manner, which not only simplifies the installation process, but also reduces the limitation on the diameter of the anchor rod, enabling the device to be applicable to the positioning and installation of anchor rods of different diameters, greatly enhancing the universality and applicability of the device.

[0028] As shown in Figure 5 The adjustment assembly 5 includes a sleeve 51 that is slidingly sleeved on the vertical limiting groove 41 on the surface of the threaded column 4, and the outer surface of the sleeve 51 is rotatably sleeved with a connecting sleeve 52. One side of the connecting sleeve 52 is connected with the adjusting ring 6 through a connecting rod, and corresponding threaded holes 55 are formed in the connecting sleeve 52 and the sleeve 51. A locking screw 58 is screwed into the threaded hole 55 to connect and position the connecting sleeve 52 and the sleeve 51 on the threaded column 4.

[0029] In use, the locking screw 58 is loosened to move the connecting sleeve 52 and the sleeve 51 vertically up and down along the limiting groove 41, and the vertical height of the alignment cylinder 91 is adjusted. If further adjustment of the angle of the alignment cylinder 91 is needed, the locking screw 58 is further loosened to move away from the threaded hole 55 in the sleeve 51, and the connecting sleeve 52 is rotated to adjust the angle of the alignment cylinder 91. When the alignment cylinder 91 is reset, the locking screw 58 is screwed into the threaded hole 55 again until it tightly abuts against the threaded groove on the surface of the threaded column 4, and the alignment cylinder 91 is limited at the appropriate position.

[0030] As a preferred scheme of the embodiment, in order to improve the stability of the limiting function of the adjusting assembly 5, the adjusting assembly 5 further comprises a threaded ring 57 and a limiting ring 59 arranged at the upper and lower ends of the sleeve 51 respectively, and the threaded ring 57 and the limiting ring 59 are threadedly connected with the threaded column 4. When the connecting sleeve 52 and the sleeve 51 slide vertically up and down, the threaded ring 57 and the limiting ring 59 can move up and down by rotating to abut against the top end and the bottom end of the connecting sleeve 52 and the sleeve 51, thereby playing a good limiting effect on the connecting sleeve 52 and the sleeve 51 and improving the stability of the adjusting assembly 5. Furthermore, in order to facilitate the rotation operation of the threaded ring 57, at least two handles 571 are arranged on the side wall of the threaded ring 57.

[0031] As a further preferred scheme of the embodiment, in order to facilitate the rotation and resetting of the connecting sleeve 52, a slot 53 is arranged on the surface of the connecting sleeve 52, the center of the slot 53 is connected with a connecting hole seat 54, and a threaded hole 55 is arranged on the connecting hole seat 54; a limiting block 56 corresponding to the slot 53 is arranged on the outer surface of the sleeve 51, and the limiting block 56 is used for limiting the rotation of the connecting sleeve 52. When the connecting sleeve 52 rotates relative to the sleeve 51, the cooperation of the slot 53 and the limiting block 56 can make the connecting sleeve 52 rotate around the circumferential surface formed by the limiting block 56, so that the alignment cylinder 91 changes the angle in the horizontal direction and is offset from the hole 1, and meanwhile, the connecting sleeve 52 can also be prevented from being separated from the sleeve 51 during the rotation. The reasonable design of the positions of the limiting block 56 and the threaded hole 55 can make the connecting sleeve 52 just return to the original position when the leftmost side of the slot 53 just abuts against the limiting block 56, at this time, the alignment cylinder 91 is re-aligned with the hole 1, and the connecting sleeve 52 can be limited by rotating the locking screw 58 into the threaded hole 55, thereby preventing the rotation of the connecting sleeve 52.

[0032] As a further preferred scheme of the embodiment, the ball 7 is further connected between the adjusting ring 6 and the connecting column 8, the ball 7 is rotatably arranged in the adjusting ring 6, the bottom end of the ball 7 is connected with the connecting column 8, a threaded channel is arranged on the side wall of the adjusting ring 6, a threaded rotating rod 92 is threadedly connected in the threaded channel, and the ball 7 can be limited by rotating the threaded rotating rod 92 into the threaded channel to abut against the surface of the ball 7. Specifically, the ball 7 can be multi-angle rotated in the adjusting ring 6, so as to drive the connecting column 8 and the alignment cylinder 91 connected with the bottom end of the ball 7 to change the angle in the vertical direction, and meanwhile, the cooperation of the threaded channel and the threaded rotating rod 92 can limit the angle change. Such a design can make the device adapt to the hole anchor rod arrangement with an inclined angle, so that the anchor rod can be as much as possible in the central position of the hole.

[0033] In addition, in order to facilitate the replacement of the alignment cylinder 91 or the connecting column 8, the top end of the alignment cylinder 91 is connected with the connecting column 8 through a bolt.

[0034] In order to facilitate the movement of the device, a handle 10 is connected to the upper side wall of the threaded column 4, and an I-shaped moving wheel 11 is installed on the bottom side wall. When the device needs to be moved, the threaded column 4 is tilted, so that the moving wheel 11 is pressed against the ground. By pulling the handle 10 in cooperation with the moving wheel 11, the device can be conveniently moved.

[0035] Working principle:

[0036] When installing the anchor rod body 2 in the mining operation, first drill a hole to form a hole 1 by a drilling machine, and then place the base 3 above the hole 1. Rotate the limiting ring 59 to make it move downward along the threaded column 4, and at the same time, loosen the locking screw 58. The sleeve 51 and the connecting sleeve 52 will slide downward along the limiting groove 41 with the downward movement of the limiting ring 59, thereby driving the adjusting ring 6 to move downward, and further driving the alignment cylinder 91 to move downward. When the lower cylinder body 912 is aligned and inserted into the hole 1 for a distance, stop rotating the limiting ring 59. At this time, the position of the alignment cylinder 91 is calibrated through the hole 1, so that the alignment cylinder 91 is on the same axis as the hole 1.

[0037] Then, reverse rotate the limiting ring 59 to make it push the sleeve 51 and the connecting sleeve 52 to slide upward along the limiting groove 41, thereby driving the lower cylinder body 912 which has been aligned with the hole 1 to move upward and away from the hole 1. When the upward movement height meets the required height for the installation of the anchor rod body 2, stop rotating the limiting ring 59. Then, disassemble the lower cylinder body 912, and then rotate the top end of the anchor rod body 2 into the threaded groove 1 913 at the bottom of the upper cylinder body 911, to complete the connection of the anchor rod body 2. In order to prevent the anchor rod body 2 from being installed and falling into the hole 1 by mistake, the locking screw 58 can be rotated out during the installation of the anchor rod body 2. By rotating the connecting sleeve 52 to drive the upper cylinder body 911 to rotate, the upper cylinder body 911 is misaligned with the hole 1, and then the connection of the anchor rod body 2 is performed. After the connection of the anchor rod body 2 is completed, the connecting sleeve 52 is reversed to rotate until the slot 53 of the connecting sleeve 52 is just in contact with the limiting block 56, and then the connecting sleeve 52 is just restored to its original position. At this time, the upper cylinder body 911 is just re-aligned above the hole 1, and then the locking screw 58 is rotated into the threaded hole 55 to connect the connecting sleeve 52 with the sleeve 51.

[0038] Then, rotate the limiting ring 59 again to make it move downward along the threaded column 4. The sleeve 51 and the connecting sleeve 52 will slide downward along the limiting groove 41 with the downward movement of the limiting ring 59, thereby driving the upper cylinder body 911 and the anchor rod body 2 to move downward. The anchor rod body 2 continues to penetrate into the hole 1, and when it reaches the appropriate position, stop rotating the limiting ring 59.

[0039] Finally, rotate the threaded ring 57 to make it move downward and abut against the top of the sleeve 51 and the connecting sleeve 52, and at the same time, tighten the locking screw 58 to limit the sleeve 51 and the connecting sleeve 52, thereby ensuring the position of the upper cylinder body 911 and the anchor rod body 2 to be stable and unchanged. Then, the cement mortar can be poured.
