Description

Technical Field

[0001] This invention relates to the field of tunnel blasting technology, and in particular to a detonator vibration damping and isolation device for tunnel blasting. Background Technology

[0002] In tunnel blasting, accurate installation of detonators is crucial for ensuring blasting effectiveness. However, a technical problem in traditional tunnel blasting is that detonators may be subjected to significant vibration and impact during installation within the blast hole, leading to instability and affecting the blasting results. This problem mainly stems from the lack of effective vibration damping and isolation mechanisms in traditional detonator installation methods, making the detonators prone to shaking during installation and reducing operational precision and efficiency.

[0003] In existing technologies, the common method for installing detonators is to directly fix them inside the blast hole, which lacks accurate positioning of the detonator and effective vibration reduction measures. Due to the special properties of detonators, their installation not only requires a high degree of precision, but also requires effective control of factors such as shock waves and gas expansion to ensure that the detonator inside the blast hole can function stably and accurately during the blasting process.

[0004] Some existing solutions attempt to reduce shock wave propagation by reinforcing the structure of the blast hole or by adding cushioning materials. However, these solutions have some problems in practical applications, such as complex structures, difficulty in implementation, and poor vibration reduction effects. This solution overcomes the shortcomings of traditional technologies and provides an advanced and practical technical solution for the field of tunnel blasting. Summary of the Invention

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one 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 is mutually exclusive with other embodiments.

[0031] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention. This embodiment provides a vibration reduction and isolation device for detonators used in tunnel blasting, including a wiring mechanism 100 and a positioning mechanism K. The positioning mechanism K fixes the detonator body 102 at a designated position inside the blast hole 101a, and a buffer plate K-1 is installed between the inner contour line of the blast hole 101a and the detonator body 102 at a designated angle, thereby consuming part of the shock wave and the pressure of gas expansion, and playing a role in vibration reduction.

[0032] Specifically, a vibration damping and isolation device for detonators used in tunnel blasting includes a wiring mechanism 100, comprising a working face 101, a detonator body 102 disposed inside the working face 101, a lead wire 103 disposed on the end face of the detonator body 102, a wire reel 104, and a blasting hole 101a disposed on the working face 101; and, The positioning mechanism K includes a buffer plate K-1 disposed on the inner wall of the blast hole 101a, a clamping assembly K-2 sleeved on the outer wall of the detonator body 102, and an anti-loosening mechanism K-3 disposed on the end face of the clamping assembly K-2.

[0033] The clamping assembly K-2 includes a limiting disk K-4 fitted into the inner wall of the blast hole 101a, a rotating cylinder K-5 that rotatably passes through the limiting disk K-4, and a swing arm K-6 rotatably disposed on the end face of the limiting disk K-4.

[0034] Furthermore, a window K-7 is provided through the outer wall of the rotating drum K-5, and a sliding sleeve K-8 is provided rotatably on the inner wall of the window K-7. The swing arm K-6 slides through the sliding sleeve K-8 and extends into the interior of the rotating drum K-5 and is provided with a fixing claw K-9.

[0035] Even better, there are three windows K-7 and three swing arms K-6. The swing arm K-6 is a long rectangular arm, and the sliding sleeve K-8 is a rectangular ring with a hollow inner rectangle. Therefore, the swing arm K-6 slides freely in the sliding sleeve K-8. At the same time, the rotation fulcrum of the swing arm K-6 on the limiting plate K-4 and the rotation fulcrum of the sliding sleeve K-8 are not on the same diameter of the limiting plate K-4. Therefore, the eccentrically set sliding sleeve K-8 can drive the swing arm K-6 to swing.

[0036] Preferably, the inner wall of the fixing claw K-9 is provided with a circular groove K-10, which fits against the outer wall of the detonator body 102. The inner wall of the rotating cylinder K-5 is provided with a cylinder K-12, and a wedge-shaped hole K-11 is opened inside the cylinder K-12. One end of the detonator body 102 fits against the wedge-shaped hole K-11.

[0037] More preferably, the outer wall of the cylinder K-12 is provided with a sliding column K-13, and the inner wall of the rotating cylinder K-5 is provided with a guide rail K-14. The sliding column K-13 is slidably disposed inside the guide rail K-14. The guide rail K-14 is a spiral arc groove, and the sliding column K-13 is a truncated cone-shaped column.

[0038] Among them, the wedge-shaped hole K-11 is a wedge-shaped groove with an inclination angle of 45°, and the diameter of the wedge-shaped hole K-11 becomes smaller and smaller as the cylinder K-12 moves inward. As a result, after the detonator body 102 is inserted into the wedge-shaped hole K-11, it will fit tightly. And because the diameter of the wedge-shaped hole K-11 becomes smaller and smaller, it will lock tighter and tighter, thus preventing the detonator body 102 from shaking after it is laid out, which would affect the set blasting effect.

[0039] Furthermore, the anti-loosening mechanism K-3 includes a thin column K-15 located on the end face of the cylinder K-12, a frustum K-16 located on the end face of the thin column K-15, a slide rail K-17 penetrating the inner wall of the rotating cylinder K-5, and a limiting rod K-18 slidably located on the inner wall of the slide rail K-17.

[0040] Among them, the end face of the limiting rod K-18 is provided with a locking block K-19, the outer wall of the locking block K-19 is provided with a slope K-20 and a right angle surface K-21 respectively, and the inner wall of the limiting rod K-18 and the slide K-17 is provided with a third elastic element K-22.

[0041] Preferably, one side of the bottom surface of the frustum K-16 is connected to the thin column K-15, and the end face of the frustum K-16 is provided with a through hole K-23, through which the locking block K-19 slides through the through hole K-23.

[0042] Preferably, the thin cylinder K-15 is a cylinder with a diameter smaller than the bottom diameter of the cylinder K-12 and the frustum K-16, thereby creating a slot between the cylinder K-12 and the frustum K-16, so that the locking block K-19 can be locked inside the slot by the right angle surface K-21 and thus be limited.

[0043] Preferably, the third elastic element K-22 is a spring, and when the third elastic element is in the initial state, it pushes the limiting rod K-18 to move into the inside of the rotating cylinder K-5, and the right angle surface K-21 is close to the inner wall of the bottom surface of the rotating cylinder K-5, while the inclined surface K-20 is away from the inner wall of the bottom surface of the rotating cylinder K-5 and slides against the outer wall of the frustum K-16.

[0044] The rotating drum K-5 is movably positioned on the bottom surface of the inner wall of the blast hole 101a, allowing the detonator body 102 to be installed on the rotating drum K-5 instead of directly on the inner wall of the blast hole 101a. The buffer plate K-1 is made of EVA material, which absorbs some of the pressure from the shock wave and gas expansion. At the same time, the detonator detonation is mainly based on positive shear stress, cutting the surrounding boreholes and forming a flat cutting surface between the two boreholes. This results in a smooth blast contour line, reducing the disturbance of the blast contour surface by the shock wave and gas expansion. Therefore, the installation position of the detonator body 102 and the buffer plate K-1 can be adjusted more easily, and the angle required for vibration reduction and isolation can be freely set.

[0045] In summary, during use, the detonator body 102 is pushed into the blast hole 101a and slid into the rotating drum K-5 until it comes into contact with the wedge hole K-11. As the detonator body 102 goes deeper, it fits more tightly with the wedge hole K-11, which pushes the cylinder K-12 to slide into the blast hole 101a. At this time, the sliding column K-13 on the outer wall of the cylinder K-12 will move relative to the guide rail K-14. Because the friction between the sliding column K-12 and the detonator body 102 is very large, the guide rail K-14 and the rotating drum K-5 will rotate, and the sliding sleeve K-8 will also rotate, which will drive the swing arm K-6 to swing towards the center of the limiting plate K-4, thereby clamping and fixing the outer wall of the detonator body 102 through the circular groove K-10 on the fixing claw K-9. At the same time, cylinder K-12 slides downward, causing thin cylinder K-15 and frustum K-16 to slide down together. When the inclined surface K-20 of the locking block K-19 comes into contact with the outer wall of frustum K-16, relative sliding occurs. Simultaneously, the limiting rod K-18 slides along the slide rail K-17 until the inclined surface K-20 and frustum K-16 disengage. The limiting rod K-18 is reset under the push of the third elastic element K-22, and the right angle surface K-21 of the locking block K-19 is locked. At this time, cylinder K-12 is limited and locked, so the rotating cylinder K-5 is also locked. The detonator body 102 is firmly fixed by the fixing claw K-9. Subsequently, the buffer plate K-1 is installed to fill the angle that needs to be damped. During this process, because the detonator body 102 is fixed, there will be no shaking, making the installation process of buffer plate K-1 faster and speeding up the work efficiency.

[0046] Example 2 Reference Figures 1-9This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but with the difference that it also includes a covering mechanism 200 and a control mechanism 300. The detonator lead is laid through the wiring mechanism 100. At the same time, the protective sleeve 202 fixes the lead 103 to the outer wall of the working face 101. While emitting a light source to indicate the direction of the wiring, it isolates the lead from the possibility of moisture and dust entering the lead and causing failure. In addition, it also makes the lead more firmly fixed in the vertical direction, so that it will not easily loosen or become entangled with other leads.

[0047] Specifically, the covering mechanism 200 includes a bracket 201, a protective sleeve 202 disposed on the outer wall of the lead wire 103 and the working face 101, and a rotatable sleeve 203 disposed on the outer wall of the bracket 201; and a control mechanism 300 includes a limiting cylinder 301 disposed on the end face of the bracket 201 and a rotating shaft 302 disposed on the end face of the wire feeding reel 104; the rotating shaft 302 slides through into the interior of the limiting cylinder 301.

[0048] The face of the working face 101 is provided with a blasting hole 101a. The detonator body 102 is located inside the blasting hole 101a. One end of the lead wire 103 is located on the face of the detonator body 102, and the other end passes through the cavity formed by the protective sleeve 202 and the outer wall of the working face 101 and is wound around the outer wall of the wire reel 104.

[0049] More preferably, the protective cover 202 consists of two layers: a leather cover 202a and an adhesive cover 202b. The adhesive surface of the adhesive cover 202b is connected to the leather cover 202a. The outer walls at both ends of the adhesive cover 202b are respectively provided with an adhesive layer 202b-1 and a symbol 202b-2.

[0050] More preferably, the marker 202b-2 consists of multiple parallel arrows at a 45° angle, used to indicate the direction of the lead 103, with the arrows pointing towards the orientation of the detonator body 102. This facilitates the operator's assessment of the wiring method, prevents entanglement and collision between the leads, and also helps in the subsequent assessment of the opening position of the blasting hole 101a.

[0051] Furthermore, the leather sleeve 202a and the adhesive sleeve 202b are normally glued together and wrapped and stored inside the sleeve 203. When in use, after separating the two, the adhesive sleeve 202b can be used to attach the lead wire 103 to the outer wall of the working face 101. The marker 202b-2 is a fluorescent marker when the lighting is poor, and a reflective strip marker when the lighting is adequate, making it easier to observe.

[0052] Preferably, the outer wall of the bracket 201 is provided with a guide wheel 201a, the guide wheel 201a, the wire feeding reel 104 and the sleeve wheel 203 are located in the same plane, and the outer wall of the bracket 201 is also provided with a sliding groove 201b.

[0053] Furthermore, a slide rod 201b-1 is slidably provided inside the slide groove 201b, a first elastic element 201b-2 is slidably sleeved on the outer wall of the slide rod 201b-1, and a connecting rod 201b-3 is provided on the outer wall of the slide rod 201b-1. The two ends of the first elastic element 201b-2 are respectively provided on the end face of the connecting rod 201b-3 and the inner wall of the slide groove 201b.

[0054] More preferably, the end face of the connecting rod 201b-3 is provided with a winding wheel 201b-4, which is located in the same plane as the sleeve wheel 203, and the sleeve 202a is wound around the outer wall of the winding wheel 201b-4.

[0055] The sliding rod 201b-1 slides in the groove 201b-2 in the radial direction of the sleeve 203 and points to the center of the sleeve 203. As a result, when the take-up roller 201b-4 moves, it can always be in contact with the sleeve 203 and make the leather sleeve 202a wind onto the take-up roller 201b-4, thereby realizing the separation of the leather sleeve 202a and the adhesive sleeve 202b.

[0056] Preferably, the lead wire 103 is normally wound around the outer wall of the wire release reel 104. The pressure roller 201b-4 is driven by a motor and is in contact with the sleeve roller 203. The lead wire 103 passes through the cavity between the pressure roller 201b-4 and the sleeve roller 203 and is in contact with the adhesive layer 202b-1 of the adhesive sleeve 202b in the cavity. Then the lead wire 103 is attached and fixed to the outer wall of the working face 101 by the adhesive sleeve 202b.

[0057] In summary, during use, the motor is first started to drive the pressure wheel 201b-4 to rotate, which causes the sleeve wheel 203 to rotate as well. When the sleeve wheel 203 rotates, the take-up wheel 201b-4 that is in contact with it also rotates, causing the leather sleeve 202a on the protective sleeve 202 to separate from the adhesive sleeve 202b. The leather sleeve 202a is driven and wound onto the outer wall of the take-up wheel 201b-4. As the number of layers wound by the take-up wheel 201b-4 increases, it can always be in contact with the sleeve 203 through the sliding of the slide rod 201b-1 and the push of the first elastic element 201b-2, that is, the spring, so as to continuously perform the function of separating the adhesive sleeve 202b and the leather sleeve 202a. Subsequently, the adhesive sleeve 202b contacts the lead wire 103 wound on the outer wall of the wire reel 104 and, under the pressure of the clamping rollers 201b-4 and the pressure plate 203, the lead wire 103 is bonded together with the adhesive layer 202b-1. Since the other end of the lead wire 103 is connected to the detonator body 102, with the appearance of tension and the pressure of the sleeve 203 on the outer wall of the face 101, the adhesive sleeve 202b adheres and fixes the lead wire 103 to the surface of the face 101. This not only indicates the arrangement of the lead wire 103, but also prevents moisture and dust from entering the interior of the lead wire 103 and causing failure, while also improving the wiring efficiency of the detonator lead wire.

[0058] Example 3 Reference Figures 1-10 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the control mechanism 300 can limit the wire feeding speed of the wire feeding reel 104 and switch the brake lock through the cooperation of the rotating shaft 302 and the limiting cylinder 301. At the same time, it can also record the length of the laid lead wire 103 through the meter counting reel 303.

[0059] Specifically, the limiting cylinder 301 has a cavity 301a inside, and a limiting ratchet 301a-1 and a speed limiting ratchet 301a-2 are respectively arranged in parallel inside the cavity 301a. The rotating shaft 302 passes through the cavity 301a and has a turntable 302a at one end.

[0060] The turntable 302a has a pawl 302a-1 on its end face for rotation. The pawl 302a-1 and the inner wall of the turntable 302a have a second elastic element 302a-2. The turntable 302a and the rotating shaft 302 can slide inside the cavity 301a but are limited and cannot leave the cavity 301a.

[0061] More preferably, there are four pawls 302a-1 and two elastic elements 302a-2, which are arranged in a circular array on the end face of the turntable 302a. The pawls 302a-1 can engage with the limiting ratchet 301a-1 and the speed limiting ratchet 301a-2 respectively.

[0062] Preferably, the limiting ratchet 301a-1 and the speed limiting ratchet 301a-2 have the same tooth shape but different number of teeth. Therefore, the outer diameter of the speed limiting ratchet 301a-2 is larger than that of the limiting ratchet 301a-1. The rotating shaft 302 slides inside the cavity 301a and coincides with the planes of the limiting ratchet 301a-1 and the speed limiting ratchet 301a-2 respectively.

[0063] Furthermore, when the turntable 302a slides, causing the pawl 301a-1 to come into contact with the plane of the limiting ratchet 301a-1, the turntable 302a and the rotating shaft 302 are limited and can only rotate in the opposite direction. The direction of rotation is opposite to the direction of rotation of the pay-off reel 104 when it is working. Therefore, in this position, the pay-off reel 104 is limited and locked.

[0064] Furthermore, when the turntable 302a slides, causing the pawl 301a-1 to come into contact with the plane of the speed-limiting ratchet 301a-2, the pawl 301a-1 and the speed-limiting ratchet 301a-2 do not contact each other when the turntable 302a rotates at low speed. However, when the speed of the pay-off reel 104 increases to the set value, the pawl 301a-1 rotates outward due to centrifugal force and comes into contact with the speed-limiting ratchet 301a-2 again. As a result, the turntable 302a and the shaft 302 are limited and can only rotate in the opposite direction. The pay-off reel 104 is limited and slowed down. Ultimately, this ensures that the workers can only lay the lead wire 103 evenly and slowly according to the set speed during the laying process, preventing violations of operating procedures.

[0065] Preferably, the sleeve 203 rotates through the inside of the bracket 201 and is connected to a transmission gear 303. The gear 303 consists of a pair of meshing gears. The other end face of the transmission gear 303 is provided with a metering disk 303, so that the length of the laid lead wire 103 can be displayed in real time, which is convenient for statistical recording.

[0066] In summary, during use, the operator first pushes the rotating shaft 302 to slide the turntable 302a to the speed-limiting ratchet 301a-2 position. When the laying device is working normally, it will drive the sleeve wheel 203 to rotate. At the same time, the transmission gear 303 connected to the sleeve wheel 203 transmits the rotation signal to the metering disc 303 through the set transmission ratio, so that the reading on the metering disc 303 matches the number of rotations of the sleeve wheel 203, that is, the length of the protective sleeve 202 and the lead wire 103 laid, thus intuitively displaying the laying length, which is convenient for the operator to record and observe. At the same time, for chemical leads, the detonation triggering time of the detonator body 102 in each blasting hole 101a can be set by the lead wire length to achieve timed blasting. Meanwhile, the operator must lay the lead wire 103 at a constant speed according to the operating specifications. When the speed exceeds the set value, it will automatically decelerate. When the laying needs to be paused to check the lead wire direction, simply slide the rotating shaft 302 in the opposite direction to lock and fix the pay-off reel 104, preventing the pay-off reel 104 from rotating on its own and causing errors. This makes it convenient to read the data from the meter counter 303, thus avoiding errors in mileage statistics.
