[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0029] like Figures 1 to 4 As shown, this utility model embodiment provides a self-locking fixing device for a focusing tube. The self-locking fixing device for a focusing tube includes a base 10, a connecting rod 20, and a top plate 30. The base 10 is used to connect the tube body 100 of the focusing tube. The two ends of the connecting rod 20 are connected to the base 10 and the top plate 30 respectively. A slide rail 40 is provided on the connecting rod 20, and a slider 50 is provided on the slide rail 40. The slide rail 40 extends from the base 10 to the top plate 30 and is inclined in a direction away from the connecting rod 20. The slider 50 has a first position and a second position on the slide rail 40. When the slider 50 moves from the first position to the second position, the distance between the slider 50 and the connecting rod 20 gradually increases, so that the slider 50 can gradually abut against the inner wall of the blast hole, thereby fixing the focusing tube into the blast hole.
[0030] Specifically, the base 10 is tightly connected to the tube body 100 of the shaped charge tube, ensuring that the shaped charge tube can be securely installed into the blast hole. The two ends of the connecting rod 20 are connected to the base 10 and the top plate 30 respectively, forming a stable frame structure. This not only enhances the stability of the entire device but also allows for adjustments to the length or tilt angle of the connecting rod 20 to accommodate blast holes of different depths and diameters. The slide rail 40 extends along the length of the connecting rod 20, and its tilt direction is away from the axis of the connecting rod 20, allowing the slider 50 to gradually expand outwards as it moves along the slide rail 40, effectively increasing the contact area with the inner wall of the blast hole.
[0031] In other words, as the slider 50 moves from the first position to the second position, the distance between the slider 50 and the connecting rod 20 gradually increases due to the inclined design of the slide rail 40. This change allows the slider 50 to gradually approach and abut against the inner wall of the blast hole, thereby firmly fixing the energy-concentrating tube inside the blast hole through friction and pressure. This makes the fixing device adaptable to blast holes of various shapes and sizes, providing greater installation flexibility and accuracy.
[0032] In summary, the self-locking fixing device for shaped charge tubes provided in this embodiment of the present invention achieves a stable and flexible fixing method through the ingenious combination of the base 10, connecting rod 20 and top plate 30, as well as the innovative design of slide rail 40 and slider 50. This not only improves the installation efficiency and safety of shaped charge tubes in blasting holes, but also provides a more reliable and efficient solution for various blasting projects.
[0033] like Figure 1 and Figure 2 As shown, in some embodiments, multiple slide rails 40 are provided, and these multiple slide rails 40 are arranged at equal angles along the outer periphery of the connecting rod 20. The slider 50 is arranged in a one-to-one correspondence with each slide rail 40. This not only improves the overall stability of the self-locking fixing device for the shaped charge tube, but also allows the device to distribute the pressure on the inner wall of the blast hole more evenly. This helps reduce the risk of deformation or damage to the blast hole caused by pressure concentration, thereby improving the safety and efficiency of blasting operations. In this embodiment, four slide rails 40 are provided.
[0034] Furthermore, the slide rail 40 includes a trapezoidal guide plate 41, with the small end 411 of the trapezoidal guide plate 41 located near the base 10 and the large end 412 of the trapezoidal guide plate 41 located near the top plate 30. The slider 50 is provided with a guide groove 51 that matches the trapezoidal guide plate 41.
[0035] Specifically, the smaller end 411 of the trapezoidal guide plate 41 is positioned near the base 10, while the larger end 412 is positioned near the top plate 30. This design allows the slide rail 40 to extend along the length of the connecting rod 20 while also having a certain tilt angle. When the slider 50 moves on the trapezoidal guide plate 41, due to the tilt design of the guide plate, the slider 50 can gradually expand outward, forming a closer contact with the inner wall of the blast hole.
[0036] The slider 50 is provided with a guide groove 51 that matches the trapezoidal guide plate 41. The shape and size of the guide groove 51 are closely matched with the trapezoidal guide plate 41, ensuring the stability and controllability of the slider 50 during movement. When the slider 50 moves along the trapezoidal guide plate 41, the guide groove 51 can guide the slider 50 to move along a predetermined path, thereby preventing the slider 50 from deviating or falling off during movement.
[0037] In addition, the trapezoidal guide plate 41 also has a certain self-locking function. When the slider 50 moves to the large end 412 of the trapezoidal guide plate 41, due to the inclination angle of the guide plate and the weight of the slider 50, the slider 50 will naturally move towards the inner wall of the blast hole and tightly abut against the hole wall. This self-locking function not only improves the stability of the shaped charge tube self-locking fixing device, but also helps to reduce the risk of the slider 50 moving or falling off due to external factors such as wind, vibration, etc.
[0038] As shown in Figure 2 , Figure 3 and Figure 4 , in the present embodiment, the guide groove 51 is arranged in an inclined manner. When the slider 50 moves from the small end 411 to the large end 412 of the trapezoidal guide plate 41, the inclined design of the guide groove 51 enables the slider 50 to gradually expand outward and form a tighter contact with the inner wall of the blast hole. This design not only improves the fit of the slider 50 with the inner wall of the blast hole, but also helps to reduce the friction and resistance generated by the movement of the slider 50.
[0039] Further, the slider 50 is provided with anti-skid pads or anti-skid textures, which not only improve the anti-skid performance of the shaped charge tube self-locking fixing device, but also enhance the stability and safety of the entire device.
[0040] As shown in Figure 1 and Figure 2 , in some embodiments, the shaped charge tube self-locking fixing device also includes a resilient member 60, one end of which is connected to the base 10 and the other end of which is connected to the slider 50, so that the slider 50 can receive a continuous pushing or pulling force from the resilient member 60 during movement, thereby ensuring that the slider 50 can tightly fit against the inner wall of the blast hole. In the present embodiment, the resilient member 60 is arranged as a spring, which is sleeved outside the connecting rod 20. The base 10 is provided with a positioning groove 11 for accommodating the spring, so as to avoid the spring from deviating.
[0041] In some embodiments, the edge of the top plate 30 is provided with an inclined guide surface 31, so that the top plate 30 can more smoothly slide into the hole when it contacts the blast hole, avoiding jamming or damage due to shape mismatch or improper angle.
[0042] As shown in Figure 2As shown, in some embodiments, the shaped charge tube self-locking fixing device further comprises a plug-in tube 70 connected with the base, the plug-in tube 70 can be movably inserted into the tube body 100 of the shaped charge tube, and a plurality of through holes 71 are provided on the plug-in tube 70, which are arranged one by one corresponding to the shaped charge holes 110 on the tube body 100. Not only can it ensure that the shaped charge tube is accurately placed at the predetermined position in the blasting hole, but also when the plug-in tube 70 is inserted into the shaped charge tube, these through holes 71 can ensure that the shaped charge holes 110 are kept unobstructed, thereby ensuring the effective transmission and release of energy when the explosive explodes, so as to realize the fine control of the blasting effect and range.
[0043] Further, the shaped charge tube self-locking fixing device further comprises a shock-absorbing pad or a shock-absorbing coating provided on the outside of the plug-in tube 70, so as to absorb and disperse the vibration energy from the explosion shock. That is, when the explosive explodes in the shaped charge tube, a huge impact force and vibration will be generated, and the shock-absorbing pad or the shock-absorbing coating can effectively absorb and disperse these energies, thereby protecting the plug-in tube 70 and the fixing device from damage.
[0044] In addition, as shown, Figure 1 An embodiment of the utility model further provides a shaped charge tube, the shaped charge tube comprises a tube body 100 and the shaped charge tube self-locking fixing device of the above-embodied shaped charge tube self-locking fixing device, and the shaped charge tube self-locking fixing device is connected with the tube body 100 through the base 10.
