Description

Technical Field

[0001] This utility model relates to the technical field of drilling positioning devices, specifically a high-precision drilling positioning device. Background Technology

[0002] Drill-and-blast method is a method of using blasting to excavate areas such as mines and tunnels. It involves drilling a hole at the excavation site, burying explosives in it, and then detonating them. Under the guidance of precise measurements by workers using equipment, multiple holes are drilled within the cross-sectional outline of the mine or tunnel, and then explosives are buried in the holes. This is followed by a cycle of detonation and slag removal. Currently, digital detonators are widely used in China for deep-hole bench blasting, especially for rock structures with complex rock structures.

[0003] In the field of borehole positioning devices, existing technologies for excavation operations in mines, tunnels, and other areas using the drill-and-blast method typically employ drilling equipment. However, in practice, the rigidity of the rock or substrate can lead to tilting or irregularities during drilling. Irregular boreholes result in uneven distribution of explosives within the hole, leading to uneven energy release during blasting. This affects the uniformity of rock fragmentation, potentially causing some areas to be over-fragmented while others are poorly fragmented, thus reducing blasting efficiency. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given the existing solidity of the rock or matrix in the above or existing technologies, tilting and irregularity may occur during drilling. Irregular blast holes will cause uneven distribution of explosives in the hole, resulting in uneven energy release of explosives during blasting. This will affect the uniformity of rock fragmentation, and may lead to over-fracture in some areas and poor fragmentation in others, thus reducing blasting efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-precision drilling positioning device, characterized in that it comprises:

[0008] The base plate has reinforcing nails protruding from its interior, and a fixing rod is fixedly installed on one side of the top of the base plate. A sleeve is fitted on the top of the fixing rod, and a positioning block is fixedly installed on the top of the sleeve. A positioning mechanism is provided inside the positioning block.

[0009] The positioning mechanism includes a hydraulic cylinder, which is fixedly installed on the top of the positioning block. A lower pressure frame is fixedly installed on the power output end of the hydraulic cylinder. The bottom end of the lower pressure frame has two axial inner walls with mounting grooves, and a lower pressure roller is rotatably connected inside the mounting groove.

[0010] As a further embodiment of this utility model: the positioning block has a positioning hole inside, and a support frame is embedded in the bottom of the positioning hole, and a bearing roller is rotatably connected to the top of the support frame.

[0011] As a further improvement of this utility model: the structure of the lower pressure frame is a U-shaped structure, and the lower pressure frame and the lower pressure roller form a rotating structure.

[0012] As a further improvement of this utility model: a reinforcing rod is fixedly installed on the other side of the top of the base plate, and an adjustment mechanism is provided above the reinforcing rod.

[0013] As a further embodiment of this utility model: the adjustment mechanism includes an adjustment sleeve, which is sleeved on the top of the reinforcing rod, and a limit ring is fixedly installed at one end of the adjustment sleeve that passes through the positioning block.

[0014] As a further improvement of this utility model: a threaded post is fixedly installed at one end of the reinforcing rod that passes through the adjusting sleeve, and a through hole is provided on the inner wall of the reinforcing rod.

[0015] As a further embodiment of this utility model: an insertion rod extends through the through hole, and a connecting cap is fitted onto one end of the insertion rod that extends out of the fixing rod; an anti-detachment plate is fixedly installed on one end of the fixing rod that extends into the sleeve.

[0016] As a further improvement of this utility model: the adjusting sleeve forms a rotating structure with the positioning block through a limiting retaining ring, and the adjusting sleeve is threadedly connected to the threaded column.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model achieves a triangular structure by designing a hydraulic cylinder, a lower pressure frame, a lower pressure roller, a support frame, and a bearing roller. This structure clamps and limits the drill rod, ensuring the stability and accuracy of the drilling process and preventing deviation or shaking. This would lead to irregularities in the hole, resulting in uneven distribution of explosives later on and affecting the overall quality of the blasting. At the same time, the lower pressure roller and the bearing roller, in contact with the rotating drill rod, can maintain the positioning while ensuring the smooth rotation of the drill rod.

[0019] 2. This utility model, through the design of an adjusting sleeve, a limiting ring, a threaded post, an insertion rod, a connecting cap, and an anti-detachment plate, allows the positioning block to be adjusted according to the height of the blast hole and drill rod by manual adjustment of the adjusting sleeve, thereby improving the overall applicability. At the same time, the stability of the positioning device is further improved by the cooperation of the insertion rod and the connecting cap. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Please see Figures 1 to 3 This is the first embodiment of the present utility model. This embodiment provides a high-precision drilling positioning device, including: a base plate 1, a reinforcing nail 2 protruding from the inside of the base plate 1, a fixing rod 3 fixedly installed on one side of the top of the base plate 1, a sleeve 4 sleeved on the top of the fixing rod 3, a positioning block 5 fixedly installed on the top of the sleeve 4, and a positioning mechanism 6 provided inside the positioning block 5.

[0031] The positioning mechanism 6 includes a hydraulic cylinder 601, which is fixedly installed on the top of the positioning block 5. A lower pressure frame 602 is fixedly installed on the power output end of the hydraulic cylinder 601. The bottom end of the lower pressure frame 602 has two axial inner walls with mounting grooves 603. A lower pressure roller 604 is rotatably connected inside the mounting grooves 603.

[0032] Specifically, the positioning block 5 has a positioning hole 605 inside, and a support frame 606 is embedded in the bottom of the positioning hole 605. The top of the support frame 606 is rotatably connected to a bearing roller 607.

[0033] Furthermore, the drill rod is supported from below by the bearing roller 607, which rotates with the drill rod to avoid increasing friction and affecting the torque rate of the drill rod.

[0034] Specifically, the lower pressure frame 602 has a U-shaped structure, and the lower pressure frame 602 and the lower pressure roller 604 form a rotating structure.

[0035] Furthermore, the drill rod is rotated and pressed against it from above by two lower pressure rollers 604, which can achieve a certain positioning effect and avoid deviation and shaking during high-precision drilling.

[0036] In use, the base plate 1 is fixed between the drill hole and the drilling machine by the reinforcing nails 2. The drill rod is inserted into the positioning hole 605 of the positioning block 5. Through the operation of the hydraulic cylinder 601, the lower pressure frame 602 drives the lower pressure roller 604 inside the placement groove 603 to abut against the bearing roller 607 rotatably connected inside the support frame 606, and limit and clamp the drill rod in a triangular shape.

[0037] In summary, the hydraulic cylinder 601 powers the two lower pressure rollers 604 to rotate and contact the drill rod on the support roller 607, which allows the drill rod to be positioned during drilling, improving the accuracy of the drilling process and preventing deviation that could result in irregular blast holes and affect the blasting effect. At the same time, the lower pressure rollers 604 and the support roller 607 are made of high-strength metal and can rotate with the drill rod, avoiding affecting the drill rod's rotation speed. The rotation method also reduces wear between the rollers and the drill rod.

[0038] Example 2

[0039] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for a high-precision drilling positioning device.

[0040] Specifically, a reinforcing rod 8 is fixedly installed on the other side of the top of the base plate 1, and an adjustment mechanism 9 is provided above the reinforcing rod 8.

[0041] Furthermore, the height of the positioning block 5 can be adjusted by setting the adjustment mechanism 9, which is suitable for drilling blast holes at different heights.

[0042] Specifically, the adjustment mechanism 9 includes an adjustment sleeve 901, which is sleeved on the top of the reinforcing rod 8, and a limit ring 902 is fixedly installed at one end of the adjustment sleeve 901 that passes through the positioning block 5.

[0043] Furthermore, the limiting ring 902 prevents the adjusting sleeve 901 from being limited by the positioning block 5 when rotating, thus preventing the adjusting sleeve 901 from being unable to rotate.

[0044] Specifically, a threaded post 903 is fixedly installed at one end of the reinforcing rod 8 that passes through the adjusting sleeve 901, and a through hole 904 is provided on the inner wall of the reinforcing rod 8.

[0045] Furthermore, the reinforcing rod 8 is threadedly connected to the adjusting sleeve 901 via the threaded post 903, so that when the adjusting sleeve 901 is rotated, the positioning block 5 can be adjusted up and down to adjust the height according to the position of the blast hole, thereby improving the overall applicability.

[0046] Specifically, an insertion rod 905 extends through the through hole 904, and a connecting cap 906 is fitted onto one end of the insertion rod 905 that extends out of the fixing rod 3. An anti-detachment plate 907 is fixedly installed on one end of the fixing rod 3 that extends into the sleeve 4.

[0047] Furthermore, the insertion rod 905 passes through the through hole 904 and simultaneously penetrates the fixing rod 3 and the reinforcing rod 8, with both ends threadedly connected by the connecting cap 906, thereby further improving the stability and firmness of the entire positioning device.

[0048] Specifically, the adjusting sleeve 901 forms a rotating structure with the positioning block 5 through the limiting ring 902, and the adjusting sleeve 901 is threadedly connected to the threaded column 903.

[0049] Furthermore, during the adjustment process, operators only need to adjust the adjusting sleeve 901 to adjust the height of the positioning device, making it suitable for processing boreholes of different heights, thereby improving the convenience and flexibility of the entire positioning device operation.

[0050] In use, the reinforcing rod 8 is threadedly connected to the adjusting sleeve 901 via the threaded post 903. The adjusting sleeve 901 is rotatably connected to the positioning block 5 via the limiting retaining ring 902. By rotating the adjusting sleeve 901, the positioning block 5 is prevented from rotating under the limitation of the fixing rod 3 and the sleeve 4, thereby adjusting the position of the positioning block 5 according to the position of the blast hole. The insertion rod 905 is inserted into the fixing rod 3 and the reinforcing rod 8 through the through hole 904 and fixed by the threaded connection of the connecting cap 906, which improves the overall stability. In conjunction with the anti-detachment plate 907, it prevents the fixing rod 3 and the sleeve 4 from detaching when sliding.

[0051] In summary, by rotating the adjusting sleeve 901, the positioning block 5 can be adjusted to follow the height of the blast hole, improving the comprehensiveness and applicability of the entire positioning device. At the same time, in conjunction with the insertion rod 905 and the connecting cap 906, the fixing rod 3 and the reinforcing rod 8 are fixed, which can resist the positioning sleeve 4 and the adjusting sleeve 901, further improving the stability and firmness of the support.
