Description

Technical Field

[0001] This utility model relates to the technical field of tunnel blasting, and in particular to an auxiliary positioning mechanism for blasting drilling. Background Technology

[0002] Tunnels are key and critical projects in the construction of transportation infrastructure such as highways and railways, and their construction quality and efficiency directly affect the construction progress and operational safety of the entire transportation line. With the vigorous development of railway construction and the continuous improvement of technology, tunnel excavation technology is also constantly innovating. Among these, drill-and-blast, shield tunneling, and tunneling machine methods are commonly used. Compared with shield tunneling and tunneling machine methods, drill-and-blast, with its strong adaptability to complex geological conditions and lower excavation costs, has stood out in the construction scenarios of hard rock tunnels, fractured rock tunnels, and a large number of short tunnels, becoming the widely used tunnel excavation method both domestically and internationally. When using drill-and-blast for tunnel excavation, scientifically and rationally determining the layout of blast holes in the excavation section is a crucial preliminary step. Tunnel blasting drilling has extremely high requirements for quality and precision; the position, direction, and depth of the blast holes must be accurate. Any deviation may lead to poor blasting results, or even cause a series of problems such as over-excavation and under-excavation, which not only affect the construction progress but also increase project costs and safety risks.

[0003] However, in actual construction, traditional positioning methods often rely on manual experience and simple measuring tools, making them susceptible to human error during operation, resulting in low positioning efficiency and difficulty in guaranteeing accuracy. Furthermore, some existing auxiliary positioning devices are complex in structure and cumbersome to install and debug, failing to meet the urgent need for rapid and accurate positioning in practical engineering projects. Therefore, this application proposes an auxiliary positioning mechanism for blasting drilling. Utility Model Content

[0009] The measuring component includes a plurality of rulers and a plurality of pointers. Each ruler is respectively disposed on the first slide rod and the second slide rod, and each pointer is respectively disposed on the positioning sleeve.

[0032] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0033] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0036] like Figures 1 to 8 As shown, in one embodiment, a blasting drill auxiliary positioning mechanism 1 includes a frame 10, a positioning component, and a measuring component. The positioning component includes a first slide rod 20, a second slide rod 21, a positioning sleeve 22, two locking blocks 23, and two push rods 24. The first slide rod 20 is slidably mounted vertically on the frame 10, and the second slide rod 21 is slidably mounted horizontally on the frame 10. The positioning sleeve 22 is used to fit the drill bit, and its two ends are slidably connected to the first slide rod 20 and the second slide rod 21, respectively. The two locking blocks 23 are slidably mounted on both ends of the positioning sleeve 22, and the two push rods 24 are screwed to both ends of the positioning sleeve 22, and are rotatably connected to the two locking blocks 23, respectively. When the two ends of the positioning sleeve 22 slide to any position on the first slide rod 20 and the second slide rod 21, the two push rods 24 are rotated by external force to push the two locking blocks 23 close to the first slide rod 20 and the second slide rod 21, so that the two locking blocks 23 and the two ends of the positioning sleeve 22 clamp the first slide rod 20 and the second slide rod 21. The measuring component includes several ruler strips 30 and several pointers 31. The ruler strips 30 are strip-shaped measuring tools. Each ruler strip 30 is respectively set on the first slide rod 20 and the second slide rod 21. Each pointer 31 is respectively set on the positioning sleeve 22. When the positioning sleeve 22 slides relative to the first slide rod 20 and the second slide rod 21, each pointer 31 indicates the value on each ruler strip 30.

[0037] It should be noted that the frame 10 consists of four support rods connected end-to-end in a frame-like structure. The structures of the first slide rod 20 and the second slide rod 21 are identical to those of the support rods. The two ends of the first slide rod 20 are slidably connected to the upper and lower ends of the frame structure, allowing the first slide rod 20 to move left and right relative to the frame structure. The two ends of the second slide rod 21 are slidably connected to the left and right ends of the frame structure, allowing the second slide rod 21 to move up and down relative to the frame structure. The first slide rod 20 and the second slide rod 21 are located on opposite sides of the frame structure, forming a cross shape relative to the frame 10. Furthermore, the outer surfaces of the two ends of the positioning sleeve 22 are slidably connected to the first slide rod 20 and the second slide rod 21, respectively. When the first slide rod 20 moves left and right relative to the frame 10, it drives the positioning sleeve 22 to slide left and right relative to the second slide rod 21. When the second slide rod 21 moves up and down relative to the frame 10, it drives the positioning sleeve 22 to slide up and down relative to the first slide rod 20. In this way, the first slide rod 20 and the second slide rod 21 together drive the positioning sleeve 22 to slide to any position relative to the frame 10. Further, two locking blocks 23 are slidably disposed at the ends of the positioning sleeve 22, respectively, where they are slidably connected to the first slide rod 20 and the second slide rod 21. Two push rods 24 are screwed onto the ends of the positioning sleeve 22, and one end of each push rod 24 is rotatably connected to the two locking blocks 23. Further, the side surfaces at both ends of the positioning sleeve 22 are slidably connected to the first slide rod 20 and the second slide rod 21, such that the two end faces of the positioning sleeve 22 are respectively close to the side surfaces of the first slide rod 20 and the second slide rod 21 that are far apart from each other. Each ruler strip 30 is respectively disposed on the side surface of the first slide rod 20 and the second slide rod 21 that is far apart from each other, and each pointer 31 is respectively disposed on the two end faces of the positioning sleeve 22, with each pointer 31 located on the side of the positioning sleeve 22 close to the first slide rod 20 and the second slide rod 21. Thus, when the two ends of the positioning sleeve 22 slide relative to the first slide bar 20 and the second slide bar 21 respectively, the pointers 31 located at both ends of the positioning sleeve 22 indicate the readings of the ruler strips 30 on the first slide bar 20 and the second slide bar 21 respectively. When the two ends of the positioning sleeve 22 slide to any position on the first slide bar 20 and the second slide bar 21, the distance that the positioning sleeve 22 moves up, down, left, and right can be accurately read.

[0038] It should be noted that when the operator moves the positioning sleeve 22, they simultaneously move it to the desired position according to the readings displayed on each pointer 31. Then, they manually rotate the two push rods 24 relative to the positioning sleeve 22. This causes the two push rods 24 to push the two locking blocks 23, which in turn slide relative to the positioning sleeve 22, approaching the first slide rod 20 and the second slide rod 21. This allows the positioning sleeve 22 and the two locking blocks 23 to clamp the first slide rod 20 and the second slide rod 21, preventing the positioning sleeve 22 from sliding relative to them. This allows the operator to quickly and accurately locate the drilling position and fix the positioning sleeve 22 at the drilling location, enabling the drilling equipment to perform drilling work quickly and improving construction efficiency.

[0039] like Figures 2 to 5 As shown, in one embodiment, the first sliding rod 20 includes a rod body 201 and two rod sleeves 202. One end of each of the two rod sleeves 202 is sleeved on the rod body 201, and the other end of each of the two rod sleeves 202 is slidably connected to the frame 10.

[0040] It should be noted that the sleeve 202 has a through hole along its axial direction, making it tend to be a tubular structure. The length of the two sleeves 202 joined together is greater than the length of the rod 201, so that when the two sleeves 202 are fitted onto the rod 201, they together enclose the rod 201. Furthermore, the outer surfaces of the two sleeves 202 are slidably connected to the upper and lower ends of the frame 10, respectively, so that the two sleeves 202 can simultaneously drive the rod 201 to move relative to the frame 10.

[0041] like Figures 1 to 5 As shown, in one embodiment, a locking post 2010 is provided on the rod body 201, and a sliding hole 2020 is provided on the rod sleeve 202. The locking post 2010 and the sliding hole 2020 are slidably engaged.

[0042] It should be noted that a locking post 2010 is provided on each of the two opposing sides of the rod body 201, and a sliding hole 2020 is provided on each of the two opposing sides of the rod sleeve 202. The two sliding holes 2020 are aligned coaxially, and both sliding holes 2020 are opened along the axial direction of the rod sleeve 202.

[0043] It should be noted that when the sleeve 202 is fitted onto the rod body 201, allowing the two locking pins 2010 to slide and engage with the two sliding holes 2020 respectively, the two sleeves 202 can extend or retract relative to the two ends of the rod body 201, and the two sleeves 202 cannot detach from the two ends of the rod body 201, thereby increasing or decreasing the distance between the two ends of the first sliding rod 20. Furthermore, the structures of the first sliding rod 20 and the second sliding rod 21 are identical to those of the supporting rods, allowing the distance between the two ends of each supporting rod to also increase or decrease. For ease of description, the four supporting rods are defined as the first supporting rod 11, the second supporting rod 12, the third supporting rod 13, and the fourth supporting rod 14, which are connected end-to-end in a frame-like structure. The two sleeves 202 on the first slide rod 20 are slidably connected to the first support rod 11 and the third support rod 13, respectively, and the two sleeves 202 on the second slide rod 21 are slidably connected to the second support rod 12 and the fourth support rod 14, respectively. As the distance between the two ends of each of the second support rods 12 and the fourth support rod 14 gradually increases, the first support rod 11 and the third support rod 13 move away from each other, so that the projected area of ​​the frame structure formed by the support rods gradually extends vertically. Since the two ends of the first slide rod 20 are slidably connected to the first support rod 11 and the third support rod 13, the first support rod 11 and the third support rod 13 respectively drive the two sleeves 202 on the first slide rod 20 to move away from each other, thereby increasing the distance between the two ends of the first slide rod 20. Furthermore, as the distance between the two ends of the first support rod 11 and the third support rod 13 gradually increases, the second support rod 12 and the fourth support rod 14 move further apart, causing the projected area of ​​the frame structure formed by the support rods to gradually extend laterally. Since the two ends of the second slide rod 21 are slidably connected to the second support rod 12 and the fourth support rod 14 respectively, the second support rod 12 and the fourth support rod 14 respectively drive the two sleeves 202 on the second slide rod 21 to move further apart, thus increasing the distance between the two ends of the second slide rod 21. Furthermore, the two ends of the positioning sleeve 22 are slidably connected to the first slide rod 20 and the second slide rod 21 respectively. As the distance between the two ends of the first slide rod 20 and the second slide rod 21 gradually increases, the sliding distance of the positioning sleeve 22 relative to the first slide rod 20 and the second slide rod 21 also increases. When the distance between the two ends of each support rod increases or decreases simultaneously, the projected area of ​​the frame structure formed by the support rods will also increase or decrease. In this way, the blasting drilling auxiliary positioning mechanism 1 of this application can adjust the size of the projected area of ​​the frame structure according to the actual blasting area on site, so that the positioning sleeve 22 has a larger range of movement, thereby meeting the needs of various blasting areas on site.

[0044] It should be noted that the first rod body 201 also includes a cylinder 203. The cylinder 203 is mounted on one of the rod sleeves 202, and the output shaft of the cylinder 203 is mounted on the other rod sleeve 202. In this way, the cylinder 203 can drive the two rod sleeves 202 to move closer to each other or further away from each other.

[0045] like Figures 3 to 5 As shown, in one embodiment, the rod sleeve 202 is provided with a clearance groove 2021, and the rod body 201 is provided with a slide rail 2011. The slide rail 2011 extends through the clearance groove 2021 relative to the rod sleeve 202, and the slide rail 2011 is slidably engaged with the positioning sleeve 22.

[0046] It should be noted that a clearance groove 2021 is provided on one side of the rod sleeve 202. The clearance groove 2021 is opened along the axial direction of the rod sleeve 202, and one end and the inner bottom wall of the clearance groove 2021 are respectively connected to the end of the rod sleeve 202 away from the frame 10 and the through hole. In this way, when two rod sleeves 202 are fitted onto the rod body 201 and are close to each other, the clearance grooves 2021 on the two rod sleeves 202 can be connected to each other. Furthermore, a slide rail 2011 is provided on one side of the rod body 201. The slide rail 2011 is opened along the axial direction of the rod body 201. When two rod sleeves 202 are fitted onto the rod body 201, the slide rail 2011 on the rod body 201 extends through the clearance groove 2021 relative to the rod sleeve 202 and slides and engages with the positioning sleeve 22.

[0047] like Figures 3 to 5 As shown, in one embodiment, a hook-shaped rail 2012 is provided on the rod sleeve 202, and the hook-shaped rail 2012 is parallel to the clearance groove 2021.

[0048] It should be noted that the hook-shaped rail 2012 tends to have a figure-7 shape. Two hook-shaped rails 2012 are provided, each located on one side of the rod 201, with the shorter ends of the hook-shaped rails 2012 close to each other. One end of each hook-shaped rail 2012 is connected to the end face of the rod sleeve 202. When the two rod sleeves 202 are close to each other, the hook-shaped rails 2012 on the two rod sleeves 202 can be aligned. Since both hook-shaped rails 2012 are parallel to the clearance groove 2021, when the slide rail 2011 extends relative to the rod sleeve 202, the slide rail 2011 is positioned between the two hook-shaped rails 2012. Furthermore, when the ends of the sliding holes 2020 on the two sleeves approach each other and abut against the two locking pins 2010, the two sleeves disengage from both ends of the rod body 201, while also leaving a portion of the structure at both ends of the slide rail 2011 between the two hook-shaped rails 2012. Specifically, there is a distance between the two ends of the sliding holes 2020 and the two end faces of the sleeves 202, and there is also a distance between the locking pins 2010 and the end faces of the rod body 201. When the sleeves 202 slide away from the rod body 201 so that the locking pins 2010 abut against one end of the sliding holes 2020, a portion of the structure on the sleeves 202 is still fitted onto the rod body 201, thus leaving a portion of the structure at both ends of the slide rail 2011 between the two hook-shaped rails 2012.

[0049] like Figures 6 to 8 As shown, in one embodiment, the positioning sleeve 22 includes a sleeve 220 and a slider 221. The slider 221 is disposed on the sleeve 220, and the hook-shaped rail 2012 and the slide rail 2011 are both slidably engaged with the slider 221.

[0050] It should be noted that the sleeve 220 is a tubular structure with both ends connected. When the drilling equipment needs to drill, the drill bit of the drilling equipment can pass through the sleeve 220 so that the sleeve 220 is fitted onto the drill bit, thereby fixing the position of the drill bit during drilling. Two sliders 221 are provided. Since the first slide rod 20 and the second slide rod 21 form a cross shape relative to the frame 10, the two sliders 221 are perpendicularly arranged on the outer wall of the sleeve 220. Furthermore, the hook-shaped rail 2012 and slide rail 2011 on the first slide rod 20 are slidably engaged with one slider 221, and the hook-shaped rail 2012 and slide rail 2011 on the second slide rod 21 are slidably engaged with the other slider 221. This allows the positioning sleeve 22 to slide relative to the first slide rod 20 and the second slide rod 21.

[0051] like Figure 6 , Figure 8 As shown, in one embodiment, the slider 221 has a side groove 2210, which is slidably engaged with the hook-shaped rail 2012.

[0052] It should be noted that side grooves 2210 are provided on both sides of the slider 221 facing each other. The side grooves 2210 connect the two ends of the slider 221 facing each other, and the two side grooves 2210 are adapted to slide and engage with the two hook-shaped rails 2012.

[0053] It should be noted that there are several sliders 221, and each slider 221 is respectively disposed at both ends of the first slider 20, the second slider 21 and the positioning sleeve 22, so that the two ends of the first slider 20 are slidably engaged with the first support rod 11 and the third support rod 13, the two ends of the second slider 21 are slidably engaged with the second support rod 12 and the fourth support rod 14, and the two ends of the positioning sleeve 22 are slidably engaged with the first slider 20 and the second slider 21.

[0054] like Figure 6 , Figure 8 As shown, in one embodiment, the slider 221 is further provided with an inner groove 2211, which is slidably engaged with the slide rail 2011.

[0055] It should be noted that the inner groove 2211 is located between the two side grooves 2210, and the inner groove 2211 is parallel to the side grooves 2210. Further, the two side grooves 2210 are slidably engaged with the two hook-shaped rails 2012, and the inner groove 2211 is slidably engaged with the slide rail 2011. Further, when the cylinder 203 drives the two rod sleeves 202 to move closer together so that the hook-shaped rails 2012 on the two rod sleeves 202 are aligned with each other, the length of the two connected hook-shaped rails 2012 is the same as the length of the slide rail 2011 and their ends are aligned. Because the side grooves 2210 on the slider 221 are slidably engaged with the hook-shaped rails 2012, and the inner groove 2211 is slidably engaged with the slide rail 2011, when the slider 221 drives the sleeve 220 to slide relative to the first slide rod 20 / second slide rod 21, the slider 221 can simultaneously slide on both the hook-shaped rails 2012 and the slide rail 2011. When the distance between the two sleeves 202 increases so that part of the slide rail 2011 is located between the two hook rails 2012, and the slider 221 is located on the sleeve 202, the slider 221 is slidably engaged with the two hook rails 2012 respectively. When the slider 221 is located at the junction of the sleeve 202 and the rod body 201, the slider 221 is slidably engaged with both the slide rail 2011 and the two hook rails 2012. When the slider 221 is located on the rod body 201, the slider 221 is slidably engaged with the slide rail 2011. In this way, when the distance between the two ends of the first slide rod 20 increases or decreases, the slider 221 can slide from one end of the first slide rod 20 to the other end with the positioning sleeve 22.

[0056] like Figures 6 to 7As shown, in one embodiment, a groove 2201 is provided on the sleeve 220, the locking block 23 slides in the groove 2201, and the push rod 24 is screwed onto the sleeve 220, with one end of the push rod 24 extending into the groove 2201 and rotatably connected to the locking block 23.

[0057] It should be noted that a groove 2201 is formed on the side of the sleeve 220 facing the first slide rod 20 and the second slide rod 21, and the locking block 23 slides within the groove 2201. The push rod 24 is a screw structure, screwed onto the positioning sleeve 22, with one end of the push rod 24 extending from the outer side of the positioning sleeve 22 into the groove 2201, and rotatably connected to the side of the locking block 23 away from the first slide rod 20 and the second slide rod 21. In this way, the operator can rotate the push rod 24 to push the locking block 23 closer to or away from the first slide rod 20 and the second slide rod 21.

[0058] like Figures 6 to 7 As shown, in one embodiment, the locking block 23 includes a push block 230 and a plurality of insert pins 231. The slider 221 has a plurality of round holes 2212, and each insert pin 231 passes through the round hole 2212 and abuts against the rod body 201 / rod sleeve 202.

[0059] It should be noted that the slider 221 has several round holes 2212, each of which passes through both sides of the slider 221. When the slider 221 slides and engages with the slide rail 2011 and the two hook-shaped rails 2012, the round holes 2212 are aligned with the slide rail 2011 and the two hook-shaped rails 2012 respectively. Furthermore, each of the insert pins 231 is located on the side of the locking block 23 away from the push rod 24. When the push rod 24 is rotated to push the locking block 23 closer to the first slide rod 20 / second slide rod 21, the locking block 23 causes each insert pin 231 to extend into the circular hole 2212 one by one, and extend out from the side of the slider 221 closer to the first slide rod 20 / second slide rod 21, so that each insert pin 231 abuts against the slide rail 2011 and the two hook-shaped rails 2012 respectively, thereby causing the slider 221 and each insert pin 231 to clamp the slide rail 2011 and the two hook-shaped rails 2012 together, so that the slider 221 cannot slide relative to the first slide rod 20 / second slide rod 21.

[0060] like Figures 1 to 2 As shown, in one embodiment, the positioning component preferably includes a corner gauge 40, which is disposed on the frame 10 and is rotatably connected to the positioning sleeve 22.

[0061] It should be noted that the angle measuring component 40 is an angle gauge structure. The angle measuring component 40 is mounted on the second support rod 12 and is located at the center of the second support rod 12. Furthermore, the positioning sleeve 22 also includes a collar 25, which is fitted onto the sleeve 220 and located between the two ends of the sleeve 220. Further, the positioning assembly also includes a wire box 50, which is mounted on the second support rod 12. The wire box 50 is a wire collector with a wire winding function; for example, the wire box 50 tends to have an automatic winding function, similar to a steel tape measure structure. One end of the wire is fixedly connected to the collar 25, and the other end of the wire is wound into the wire box 50 through the axis of the angle measuring component 40. Thus, when the positioning sleeve 22 slides relative to the frame 10, the value on the angle measuring component 40 can be read based on the wire, ensuring the accuracy of the positioning angle.

[0062] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
