The quality of borehole blasting directly impacts the overall production of the open-pit mine. The layout of the borehole locations is the first step before drilling, and the accuracy of the borehole location is a major factor in whether the drilling rig can carry out construction according to the design. Therefore, the layout of the borehole locations is particularly important in open-pit mines.

[0004] In the prior art, Chinese utility model patent application number CN201020554848.6 discloses a drilling locator, including a sleeve, limiting blocks, support legs, and a hole position indicator rod. At least three downward-facing support legs are provided on the outer edge of the sleeve. The middle part of the hole position indicator rod is fitted inside the sleeve. Limiting blocks are provided at intervals at the upper and lower ends of the sleeve containing the hole position indicator rod, and the sleeve and the hole position indicator rod are in clearance fit. However, the above technology suffers from unreliable support, especially during drilling when the drill rod vibrates at a high frequency, making it difficult for the support legs to provide effective support and stability, and the device is prone to tipping over. Therefore, there is an urgent need for a stabilizing device for drilling locators. Utility Model Content

[0026] Please refer to Figures 1 to 5 , Figure 1 , Figure 5 This application provides a schematic diagram of the overall structure of a borehole locator stabilization device according to some embodiments. Figure 2 for Figure 1 The stabilizing device is shown in a bottom view. Figure 3 for Figure 1 A top view of the stabilizing device shown; Figure 4 for Figure 3 Sectional view at point AA.

[0027] This application discloses a drilling locator stabilization device, comprising a fixed cover 1, a drilling unit, a stabilization unit 4, and a power source. The fixed cover 1 comprises an upper cover 11 and a lower cover 12, which are slidably connected. The drilling unit comprises a drilling motor 2, a drill rod 3, and a drill bit. The drilling motor 2 is fixedly connected to the top of the upper cover 11, and its output shaft is fixedly connected to the drill rod 3. A drill bit is provided at the bottom of the drill rod 3. The stabilization unit 4 comprises a first stabilizing element 41 and a second stabilizing element. 42. The first stabilizing member 41 includes a first ring body 411 and a first connecting rod 412. The first ring body 411 is rotatably engaged with the drill rod 3. The two ends of the first connecting rod 412 are respectively fixedly connected to the first ring body 411 and the upper cover 11. The second stabilizing member 42 is located below the first stabilizing member 41. The second stabilizing member 42 includes a second ring body 421 and a second connecting rod 422. The two ends of the second connecting rod 422 are respectively fixedly connected to the second ring body 421 and the lower cover 12. The power source is a hydraulic cylinder 5, which is used to drive the upper cover 11 to move up and down.

[0028] The upper cover 11 and the lower cover 12 are slidably connected. The hydraulic cylinder 5 drives the upper cover 11 to move, thereby controlling the working state of the drilling unit. The first ring 411 is sleeved on the drill rod 3 to minimize the shaking of the drill rod 3. Furthermore, the first connecting rod 412 is a shock-absorbing spring, which can better reduce vibration. The second connecting rod 422 is fixed to the lower cover 12, which improves the overall stability of the lower cover 12.

[0029] The upper cover 11 and the lower cover 12 are hollow cylindrical structures with open bottoms. The diameter of the lower cover 12 is larger than that of the upper cover 11. The larger diameter of the lower cover 12 can improve the overall stability of the device.

[0030] The upper cover 11 is provided with a fixing plate 6 on its outer wall, and the hydraulic cylinder 5 is fixed to the upper wall of the lower cover 12. The output shaft of the hydraulic cylinder 5 is fixed to the bottom of the fixing plate 6. The working status of the drilling unit can be controlled in a timely manner through the movement of the hydraulic cylinder 5, which improves safety.

[0031] Furthermore, the upper cover 11 has a protrusion 111 on its outer wall and the lower cover 12 has a groove. The protrusion 111 cooperates with the groove. After the hydraulic cylinder 5 works, it drives the fixing plate 6 to move up and down. The protrusion 111 of the upper cover 11 moves up and down along the groove. The upper cover 11 and the lower cover 12 can be a sliding guide rail to enable relative movement between the upper cover 11 and the lower cover 12.

[0032] The lower cover 12 has a gap 7, which allows staff to easily observe the working status of the drilling unit. Furthermore, the gap 7 has a certain width, which facilitates the replacement and maintenance of the drill rod 3 and the drill bit.

[0033] The diameter of the second ring 421 is larger than the diameter of the drill rod 3. The function of the second ring 421 is to improve the overall stability of the lower cover 12. The stability of the lower cover 12 can be better achieved by the fixed connection between the second connecting rod 422 and the second ring 421. The second stabilizing member 42 is located in the lower part of the lower cover 12 as much as possible.

[0034] The bottom of the lower cover 12 is provided with a sturdy ground nail 8 to increase the overall fixation of the device, prevent the device from moving laterally, and improve the positioning effect. Multiple ground nails are provided.

[0035] The number of first links 412 is 5, and the number of second links 422 is 6. The first links 412 and the second links 422 will not obstruct the operation of the laser positioner. As a further improvement of this application, the number of first links 412 and second links 422 is the same, and they overlap in the vertical direction to avoid affecting the laser positioner.

[0036] The upper cover 11 is equipped with a laser locator on its inner wall. The laser locator can perform laser positioning, thereby achieving a good positioning and drilling effect. Combined with the stabilizing effect of the lower cover 12 and the stable ground nail 8, the overall drilling positioning of the device is more accurate.

[0037] As a further improvement of this utility model, the lower cover 12 is a hollow frustum structure. The increased bottom area of ​​the frustum structure can better prevent the lower cover 12 from shaking and improve its stability.

[0038] In use, this application first uses a laser locator to determine the drilling position. The laser locator can perform laser positioning, thereby achieving a good positioning and drilling effect. The lower cover 12 is fixed to the ground using a stabilizing ground nail 8. The lower cover 12 is fixed to the drilling unit. The lower cover 12 has a cylindrical structure, which provides better stability. Then, the hydraulic cylinder 5 is controlled to move the upper cover 11 downward. After moving to the appropriate position, the drilling motor 2 is turned on. The drilling motor 2 drives the drill rod 3 and the drill bit to perform the drilling operation. After the drilling is completed, the drilling motor 2 stops working, and the hydraulic cylinder 5 controls the upper cover 11 to move upward, thus loosening the fixing ground nail.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
