Description

Technical Field

[0001] This utility model relates to the field of blasting engineering technology, and in particular to a digital electronic detonator auxiliary positioning device. Background Technology

[0002] Digital electronic detonators are a new type of detonating device that achieves precise delay and safe detonation through digital control. They can accurately control the blasting time, sequence, and energy, reducing hazards such as blasting vibration and flyrock, improving blasting safety and efficiency. They can also be operated remotely, reducing human risk. They have a wide range of applications, including mining, engineering construction, urban demolition, and water conservancy projects, and are particularly suitable for complex environments with high precision and safety requirements.

[0003] The digital electronic detonator auxiliary positioning device secures the detonator to the blasting hole or the surface of the object to be blasted by mounting it on a fixed-size bracket, ensuring precise positioning and preventing displacement. Its built-in buffer component reduces vibration and impact, adapts to different detonator specifications, and is compatible with the signal transmission of digital control systems. Applications include detonator positioning in deep-hole blasting in mining, precise fixing of contour holes during tunnel excavation, directional blasting of complex structures in building demolition, and rock embankment blasting in water conservancy projects—scenarios requiring strict control of the detonation point—improving blasting accuracy and safety.

[0004] In existing technologies, some electronic detonator auxiliary positioning devices mount the detonator on a fixed-size bracket. However, the fixed-size bracket makes it difficult to accommodate electronic detonators of different sizes, leading to problems such as clamping too loosely or too tightly during installation. If the bracket is too loose, the detonator may shift due to vibration and impact before detonation, affecting detonation accuracy and safety. If the bracket is too tight, it may squeeze the detonator housing, wiring, or interfaces, causing structural damage, signal failure, or even the risk of accidental detonation. To address these issues, a digital electronic detonator auxiliary positioning device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a digital electronic detonator auxiliary positioning device, which aims to improve the existing electronic detonator auxiliary positioning devices by installing the detonator on a fixed-size bracket. However, the fixed-size bracket makes it difficult to adapt to the size of electronic detonators of different sizes, resulting in problems such as clamping too loosely or too tightly during installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A digital electronic detonator auxiliary positioning device includes a mounting shell, a fixing cone fixedly connected to the bottom of the mounting shell, an installation mechanism installed inside the mounting shell, and a fixing component installed inside the installation mechanism.

[0008] The installation mechanism includes a lever, a rotating ring fixedly connected to the outer wall of the lever, a plurality of control grooves opened on the inner wall of the rotating ring, a sliding rod slidably connected to the inner wall of the rotating ring, a connecting block fixedly connected to the top of the sliding rod, a clamping plate fixedly connected to the top of the connecting block, and a buckle assembly installed on the top of the rotating ring.

[0009] As a further description of the above technical solution:

[0010] The buckle assembly includes a limiting post, the bottom of which is slidably connected to the top of the rotating ring one. A return spring is fixedly connected inside the mounting shell, the bottom end of which is fixedly connected to the top of the limiting post. The top of the rotating ring one is rotatably connected inside the mounting shell.

[0011] As a further description of the above technical solution:

[0012] The fixing assembly includes a rotating plate, a control ring is fixedly connected to the outer wall of the rotating plate, the inner wall of the control ring is rotatably connected to the inner wall of the mounting shell, a plurality of connecting rods are fixedly connected to the inner side of the control ring, and a threaded rod is fixedly connected to the other end of the plurality of connecting rods. A grounding assembly is installed on the outer wall of the fixing assembly.

[0013] As a further description of the above technical solution:

[0014] The bottom end of the threaded rod is rotatably connected to the top of the fixed cone, and the outer wall of the threaded rod is threaded with a threaded column.

[0015] As a further description of the above technical solution:

[0016] The outer wall of each threaded column is rotatably connected to a plurality of rotating rods, and the other end of each of the plurality of rotating rods is rotatably connected to an outer support plate;

[0017] As a further description of the above technical solution:

[0018] The grounding assembly includes a sliding plate, the top of which is fixedly connected to the bottom of the outer support plate, and a control rod is fixedly connected to the inner wall of the sliding plate. The bottom of the control rod is slidably connected to the top of the fixed cone.

[0021] As a further description of the above technical solution:

[0022] The inner wall of the rotating ring is provided with multiple limiting grooves, the bottom of the limiting post is detachably connected to the inner wall of the limiting groove, and the outer wall of the sliding rod is slidably connected to the inner wall of the control groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the movement of the sliding rod causes the top connecting block and clamping plate to retract inward along the shape of the control groove, thereby changing the inner diameter. This allows the clamping plate to hold the electronic detonator, making the electronic detonator more stably fixed inside the mounting shell. By changing the size of the clamping plate opening, different sizes of electronic detonators can be clamped, thereby improving the applicability of the device.

[0025] 2. In this utility model, the control rod slides on the inner wall of the groove through the sliding plate at the bottom of the outer support plate, thereby making the outer support plate move outward more stably. The movement of the outer support plate drives the auxiliary pile to move outward, thereby making the contact area between the device and the underground soil larger, thus better fixing the electronic detonator at the landmark.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a digital electronic detonator auxiliary positioning device, including a mounting shell 1. The mounting shell 1 serves as the mounting carrier for the electronic detonator, providing installation space for subsequent components. A fixing cone 2 is fixedly connected to the bottom of the mounting shell 1. The fixing cone 2 is used to insert the device into the ground to initially connect the device to the ground surface. An installation mechanism 3 is installed inside the mounting shell 1. The installation mechanism 3 is used to clamp and fix the electronic detonator and is one of the core functional components of the device. A fixing component 4 is installed inside the installation mechanism 3. The fixing component 4 is used to stably fix the device and the electronic detonator at the designated ground surface to enhance the installation stability of the device.

[0034] The mounting mechanism 3 includes a lever 31, which acts as an operating component. By rotating the lever 31, it drives the rotating ring 32 to rotate, thereby triggering the clamping action of the clamping plate 36. The rotating ring 32 is fixedly connected to the outer wall of the lever 31. As the rotating ring 32 rotates with the lever 31, the control groove 33 on its inner wall guides the sliding rod 34 to move, providing power for the contraction of the clamping plate 36. The inner wall of the rotating ring 32 has multiple control grooves 33. The shape of the control grooves 33 determines the movement trajectory of the sliding rod 34, causing the sliding rod 34 to drive the clamping plate 36 to contract inward to change its inner diameter. The sliding rod 34 is slidably connected to the inner wall of the rotating ring 32. The sliding rod 34 slides in the control groove 33, converting the rotational motion of the rotating ring 32 into its own linear motion, thereby driving the top connecting block 35 and the clamping plate 36 to move. The top of the sliding rod 34 is fixedly connected to the connecting block 35, which connects the sliding rod 34 and the clamping plate 36, transmitting the movement of the sliding rod 34 to the clamping plate 36 so that the clamping plate 36 moves synchronously.

[0035] A clamping plate 36 is fixedly connected to the top of the connecting block 35. The clamping plate 36 changes the size of the opening by contracting inward, thereby clamping electronic detonators of different sizes and improving the applicability of the device. A latching assembly 37 is installed on the top of the rotating ring 32. After the clamping plate 36 clamps the electronic detonator, the latching assembly 37 fixes the position of the rotating ring 32 to prevent it from loosening and ensure clamping stability. The latching assembly 37 includes a limiting post 371. The limiting post 371 springs into the limiting groove 373 under the action of the return spring 372. The limiting post 371 limits and fixes the rotating ring 32 by cooperating with the limiting groove 373. The bottom of the limiting post 371 is slidably connected to the top of the rotating ring 32. The limiting post 371 slides on the top of the rotating ring 32 so that it can be accurately inserted into the limiting groove 373 when the rotating ring 32 rotates to the appropriate position. A return spring 372 is fixedly connected inside the mounting shell 1. The return spring 372 stores elastic potential energy and releases elastic force when fixation is needed to push the limiting post 371 downward so that it is inserted into the limiting groove 373.

[0036] The bottom end of the return spring 372 is fixedly connected to the top of the limiting post 371. The direct connection between the return spring 372 and the limiting post 371 ensures effective transmission of the elastic force, allowing the limiting post 371 to reliably engage with the limiting groove 373. The top of the rotating ring 32 is rotatably connected to the inside of the mounting housing 1. The rotating ring 32 rotates inside the mounting housing 1, providing stable rotational support and ensuring smooth operation when the lever 31 drives it to rotate. The inner wall of the rotating ring 32 has multiple limiting grooves 373, which correspond to different rotational positions of the rotating ring 32 and are connected to the limiting grooves 373. The column 371 works together to achieve multi-position fixation of the rotating ring 32 to meet the clamping requirements of electronic detonators of different sizes. The bottom of the limiting column 371 is detachably connected to the inner wall of the limiting groove 373. The detachable connection between the limiting column 371 and the limiting groove 373 ensures the stability during fixation and facilitates the subsequent rotation of the lever 31 to adjust the opening of the clamping plate 36. The outer wall of the sliding rod 34 is slidably connected to the inner wall of the control groove 33. The sliding connection between the sliding rod 34 and the control groove 33 ensures that the sliding rod 34 can move strictly according to the trajectory of the control groove 33, so that the contraction action of the clamping plate 36 is precise and controllable.

[0037] Reference Figure 1 , Figure 2 and Figure 4The fixing component 4 includes a rotating plate 41. The rotating plate 41 serves as the operating component of the fixing component 4. By rotating, it drives the control ring 42 to rotate, thereby triggering the expansion action of the outer support plate 45. The outer wall of the rotating plate 41 is fixedly connected to the control ring 42. The control ring 42 rotates with the rotating plate 41 and transmits the rotational motion to the threaded rod 48 through the inner connecting rod 43 to provide power for the expansion of the outer support plate 45. The inner rotatable connection of the control ring 42 is to the inner wall of the mounting shell 1. The control ring 42 rotates on the inner wall of the mounting shell 1, and the mounting shell 1 provides rotational support for it to ensure that the rotation process is smooth and reliable. Multiple connecting rods 43 are fixedly connected to the inner side of the control ring 42. The multiple connecting rods 43 are evenly distributed to ensure that the rotational force of the control ring 42 can be evenly transmitted to the threaded rod 48 to make the threaded rod 48 rotate.

[0038] The other end of multiple connecting rods 43 is fixedly connected to a threaded rod 48. The threaded rod 48 rotates under the drive of the connecting rods 43, and the thread on its outer wall cooperates with the threaded column 46 to convert the rotational motion into the up and down movement of the threaded column 46. The outer wall of the fixing component 4 is equipped with a ground insertion component 47. The ground insertion component 47 expands the contact area with the underground soil through the outer support plate 45 and the auxiliary pile 474 to improve the fixing strength of the device underground. The bottom end of the threaded rod 48 is rotatably connected to the top of the fixing cone 2. The fixing cone 2 provides a rotation fulcrum for the bottom end of the threaded rod 48 to ensure the bottom of the threaded rod 48 is stable and avoids shaking when it rotates. The outer wall of the threaded rod 48 is threadedly connected to the threaded column 46. The threaded column 46 moves up and down with the rotation of the threaded rod 48 and drives the outer support plate 45 to expand or contract through the rotating rod 44 on its outer wall.

[0039] Multiple rotating rods 44 are rotatably connected to the outer wall of the threaded column 46. The multiple rotating rods 44 are symmetrically distributed, which converts the movement of the threaded column 46 into the lateral expansion force of the outer support plate 45, so that the outer support plate 45 is evenly stressed. The other end of the multiple rotating rods 44 is rotatably connected to the outer support plate 45. The outer support plate 45 expands outward under the drive of the rotating rods 44 to increase the contact area between the device and the underground soil and enhance the fixing effect. The ground insertion component 47 includes a sliding plate 471. The sliding plate 471 moves with the outer support plate 45 and slides in the slide groove 473 through the control rod 472 to provide guidance and support for the movement of the outer support plate 45. The top of the sliding plate 471 is fixedly connected to the bottom of the outer support plate 45. The fixed connection between the sliding plate 471 and the outer support plate 45 ensures that the two move synchronously and makes the expansion action of the outer support plate 45 more stable.

[0040] A control rod 472 is fixedly connected to the inner wall of the sliding plate 471. The control rod 472 is fixed to the sliding plate 471 and moves with the sliding plate 471. It slides within the groove 473 to limit the movement trajectory of the sliding plate 471 and prevent the outer support plate 45 from shifting. The bottom of the control rod 472 is slidably connected to the top of the fixed cone 2. The top of the fixed cone 2 provides a sliding surface for the control rod 472 to ensure smooth sliding of the control rod 472 and thus ensure stable movement of the outer support plate 45. The top of the fixed cone 2 has a groove 473. The shape of the groove 473 is related to the control rod 472. The movement trajectory matching of rod 472 provides precise guidance for control rod 472, causing the outer support plate 45 to expand in a predetermined direction. The outer wall of control rod 472 is slidably connected to the inner wall of slide groove 473. The sliding connection between control rod 472 and slide groove 473 ensures that the outer support plate 45 will not tilt during expansion, improving the stability and reliability of the action. An auxiliary pile 474 is fixedly connected to the outer wall of the outer support plate 45. The auxiliary pile 474 is inserted into the soil as the outer support plate 45 expands, further increasing the friction and interlocking force between the device and the ground, making the fixation more secure.

[0041] Working principle: When it is necessary to fix the electronic detonator, the detonator is inserted into the inner side of multiple clamping plates 36. Then, the lever 31 is rotated. The rotation of the lever 31 drives the rotating ring 32 to rotate. The rotation of the rotating ring 32 causes the sliding rod 34 inside the control groove 33 to move along the shape of the control groove 33. At this time, the movement of the sliding rod 34 causes the top connecting block 35 and the clamping plate 36 to contract inward along the shape of the control groove 33, thereby changing the inner diameter. This allows the clamping plate 36 to hold the electronic detonator. When the clamping plate 36 holds the electronic detonator, the rotation of the lever 31 can be stopped. At this time, the return spring 372 will release elastic potential energy and push the limiting post 371 into the inner wall of the limiting groove 373, thereby fixing the position of the rotating ring 32. This makes the electronic detonator more stably fixed inside the mounting shell 1. By changing the size of the clamping plate 36, different sizes of electronic detonators can be clamped, thereby improving the applicability of the device.

[0042] When it is necessary to fix the device along with the electronic detonator to a designated landmark, the mounting shell 1 is inserted into the ground where it needs to be fixed. When the mounting shell 1 drives the fixing cone 2 to be inserted into the ground, the rotating plate 41 is rotated. The rotation of the rotating plate 41 drives the control ring 42 to rotate. The rotation of the control ring 42 drives the threaded rod 48 to rotate through the connecting rod 43. The rotation of the threaded rod 48 realizes the rotation of the rotating rod 44. The rotation of the rotating rod 44 expands the outer support plate 45 to the outside. At this time, the sliding plate 471 at the bottom of the outer support plate 45 drives the control rod 472 to slide on the inner wall of the groove 473, so that the outer support plate 45 moves more stably to the outside. The movement of the outer support plate 45 drives the auxiliary pile 474 to move to the outside, thereby increasing the contact area between the device and the ground soil, and thus better fixing the electronic detonator to the landmark.
