Description

Technical Field

[0001] The utility model relates to the technical field of engineering blasting, in particular to a multifunctional interval charging control device for blasting operations. Background Art

[0002] Interval charging is a method in which the explosives loaded into the blasthole are divided into several sections, and each section is separated by materials or devices to form a non-continuous column. It is widely used in the field of engineering blasting. The use of interval charging can effectively reduce the peak particle velocity of blasting vibration and minimize the transition damage of the rock mass.

[0003] For example, the public document with application number 202121913869.7 discloses a multifunctional interval charging control device for blasting operations. The adjustment structure of the utility model can adjust the diameter size used, so that the interval charging control device can adapt to blastholes of different apertures, so that the interval charging control device can be more stable when installed in blastholes of different apertures, and avoid errors caused by shaking. However, when adjusting the diameter size, the multifunctional interval charging control device for blasting operations needs to adjust each support rod independently and separately, and then screw and fix them one by one with bolts. The adjustment method is relatively cumbersome. If there are multiple gun barrels that need to be loaded and separated with a large number of blasting parts, this adjustment method is extremely time-consuming and inefficient, affecting the loading efficiency of the blasting parts. At the same time, after adjusting the diameter, the device only uses the left and right end points for inner wall support, so that when supporting, there are still large gaps at the other two ends. The spacing device is easy to tilt in the gaps at both ends, making it difficult to maintain the stability of the support for the blasting parts.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a multifunctional interval charging control device for blasting operations is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a multifunctional interval charging control device for blasting operations to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional interval charging control device for blasting operations, comprising an upper support plate, a first screw rod is rotatably arranged below the surface of the upper support plate through a bearing, a lower support plate is arranged below the upper support plate, a second screw rod is rotatably arranged above the middle part of the surface of the lower support plate through a bearing, the thread directions of the first screw rod and the second screw rod are opposite, the surfaces of the first screw rod and the second screw rod are both threadedly connected with an adjustment plate, four first movable rods are evenly distributed around the surface of the adjustment plate and are rotatably arranged through a rotating shaft seat, the ends of the first movable rods are rotatably arranged with second movable rods through a rotating shaft, and the ends of the second movable rods are rotatably connected to the surfaces of the upper support plate and the lower support plate through the rotating shaft seat.

[0007] Preferably, a groove is provided in the middle of the upper surface of the upper support plate, and positioning screw holes are evenly distributed at the lower edge of the inner surface of the groove.

[0008] Preferably, the upper end of the first screw rod passes through the upper support plate and a rotating plate is fixedly provided inside the groove, and the rotating plate is kept horizontal with the upper support plate.

[0009] Preferably, a through hole is provided on the surface edge of the rotating plate, and the through hole can correspond to the positioning screw hole.

[0010] Preferably, a fixing screw hole is provided on one side below the surface of the first screw rod, and a convergence groove is provided at the bottom end of the first screw rod.

[0011] Preferably, a movable plate is fixedly mounted on the upper end of the second screw rod, and the movable plate slides inside the convergence groove.

[0012] Preferably, the surface of the movable plate is evenly distributed with adjusting screw holes, and the adjusting screw holes and the fixing screw holes can correspond to each other.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with an upper support plate, a first screw rod, a lower support plate, a second screw rod, an adjustment plate, a first movable rod and a second movable rod. By rotating the first screw rod to drive the second screw rod to rotate, the position of the upper support plate is manually fixed, thereby limiting the rotation of the adjustment plate, so that the adjustment plate is pushed by the thread to move in the opposite direction or in the reverse direction. When the adjustment plate moves toward the upper support plate and the lower support plate, as the distance between the adjustment plate and the upper and lower plate bodies becomes smaller, the four groups of the first movable rods and the second movable rods gradually protrude outward, expanding the diameter of the device, thereby being able to flexibly adjust the diameter of the device according to the requirements of gun barrels with different diameters, so that the first movable rod The connecting end of the second movable rod protrudes, stably fits on the inner surface of the gun barrel, avoids shaking of the device, and makes the interval charge control device more stable when installed in gun holes of different apertures, and avoids errors caused by shaking. Four oppositely arranged points are used for common positioning. According to the characteristics of the circular surface, the surrounding fit can be made more stable, and the stability of the device separation is further improved to ensure that no deviation occurs. When the device is not used, the first screw rod is driven by the second screw rod by rotating the first screw rod in the opposite direction, so that the first movable rod and the second movable rod can be converged close to the center, which greatly reduces the volume of the device and is convenient for carrying and storage.

[0015] 2. The utility model sets the groove, the positioning screw hole, the rotating plate, the through hole and the fixing screw hole. The groove makes the rotating plate sink, so that the rotating plate and the upper support plate form the same horizontal plane, ensuring the flatness of the upper support plate and avoiding the explosion piece from tilting when placed. The rotating plate can rotate synchronously with the first screw rod. After the first screw rod stops rotating, the bolt is inserted through the through hole and screwed into the positioning screw hole at the nearest corresponding point, so that the rotating plate can be fixed, so that the rotation position of the first screw rod is fixed, avoiding the influence of vibration force or other external force factors to cause the first screw rod to rotate twice, affecting the support stability of the first movable rod and the second movable rod;

[0016] 3. The utility model ensures that the first screw rod can drive the second screw rod to rotate synchronously by setting the fixing screw hole, the convergence groove, the movable plate and the adjusting screw hole, and the convergence groove and the movable plate are all set in the same straight line matching. By sliding the movable plate inside the convergence groove, the distance between the second screw rod and the first screw rod can be adjusted to change the overall spacing height of the device. The height of the device can be fixed by screwing the bolt into the fixing screw hole and continuing to screw it into the adjusting screw hole corresponding to the nearest position, so that the loading interval length of each interval blasting component can be flexibly adjusted in the interval charging of blasting operations.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2 As shown, a multifunctional interval charging control device for blasting operation comprises an upper support plate 1, a first screw rod 2 is rotatably arranged below the surface of the upper support plate 1 through a bearing, a lower support plate 3 is arranged below the upper support plate 1, a second screw rod 4 is rotatably arranged above the middle part of the surface of the lower support plate 3 through a bearing, the thread directions of the first screw rod 2 and the second screw rod 4 are opposite, the surfaces of the first screw rod 2 and the second screw rod 4 are both threadedly connected with an adjusting plate 5, four first movable rods 6 are evenly distributed around the surface of the adjusting plate 5 and are rotatably arranged through a rotating shaft seat, the ends of the first movable rods 6 are rotatably arranged with second movable rods 7 through a rotating shaft, and the ends of the second movable rods 7 are rotatably connected to the surfaces of the upper support plate 1 and the lower support plate 3 through a rotating shaft seat.

[0024] Furthermore, the four sides of the adjustment plate 5 are fixed in position with the upper support plate 1 and the lower support plate 3 by the first movable rod 6 and the second movable rod 7. When the first screw rod 2 and the second screw rod 4 rotate, the upper support plate 1 only needs to be positioned manually, so that the adjustment plate 5 can be pushed by the threads and move up and down.

[0025] Furthermore, the thread directions of the first screw rod 2 and the second screw rod 4 are opposite, so that the movement directions of the upper and lower adjustment plates 5 are opposite.

[0026] Furthermore, during the movement of the adjustment plate 5, they move in opposite directions to each other, thereby pushing the first movable rod 6 and the second movable rod 7 to extend outward, and flexibly and adaptively adjust the diameter of the entire supporting device according to the diameter of the gun barrel. By moving in opposite directions to each other, the first movable rod 6 and the second movable rod 7 can be converged in the middle of the box, thereby reducing the size of the device and facilitating carrying and storage of the device.

[0027] Furthermore, the first movable rod 6 and the second movable rod 7 are arranged in four groups of eight in pairs, distributed in a cross shape. In the circular surface, after supporting the four end points that are perpendicular to each other along the axis, it can be ensured that no tilting occurs in the circular surface, and the plane diameter can be stably adjusted for support and blocking.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, a groove 8 is opened in the middle part of the upper surface of the upper support plate 1, and positioning screw holes 9 are evenly distributed at the lower edge of the inner surface of the groove 8. The upper end of the first screw rod 2 passes through the upper support plate 1 and a rotating plate 10 is fixedly arranged inside the groove 8, and the rotating plate 10 is kept horizontal with the upper support plate 1. A through hole 11 is opened on the surface edge of the rotating plate 10, and the through hole 11 can correspond to the positioning screw hole 9, a fixing screw hole 12 is opened on one side below the surface of the first screw rod 2, and a convergence groove 13 is opened at the bottom end of the first screw rod 2, a movable plate 14 is fixedly installed on the upper end of the second screw rod 4, and the movable plate 14 is located in the convergence groove 13 and slides, and the surface of the movable plate 14 is evenly distributed with adjusting screw holes 15, and the adjusting screw holes 15 and the fixing screw holes 12 can correspond to each other.

[0029] Furthermore, the groove 8 allows the rotating plate 10 to be installed downward, so that the rotating plate 10 and the upper support plate 1 form the same horizontal plane, ensuring the flatness of the upper support plate 1 and preventing the blasting parts from tilting when placed.

[0030] Furthermore, the rotating plate 10 is fixedly connected to the first screw rod 2 , and the first screw rod 2 can be driven to rotate by rotating the rotating plate 10 .

[0031] Furthermore, the bolt passes through the through hole 11 and is screwed into the positioning screw hole 9, so as to fix the position of the rotating plate 10, and then position the first screw rod 2, thereby preventing the first screw rod 2 from rotating twice due to external force factors, affecting the size of the unfolded surface of the first movable rod 6 and the second movable rod 7.

[0032] Furthermore, the movable plate 14 is slidably disposed inside the convergence groove 13 , and the movable plate 14 and the convergence groove 13 are in a straight line shape, and the movable plate 14 and the convergence groove 13 are mutually interlocked to realize the mutual transmission of the first screw rod 2 and the second screw rod 4 .

[0033] Furthermore, by sliding between the converging groove 13 and the movable plate 14 , the movable plate 14 can be pulled to extend the height of the entire device, thereby adjusting the interval height of the explosive installation.

[0034] Furthermore, the fixing screw hole 12 and the adjusting screw hole 15 can correspond to each other, and the height of the device can be fixed by screwing the bolts.

[0035] Working principle: When using the multifunctional interval charging control device for blasting operations, first, according to the different interval heights of the explosive assembly, outside the barrel, the movable plate 14 is stretched outward through the convergence groove 13, and then the bolt is passed through the fixing screw hole 12 and screwed into the corresponding adjusting screw hole 15 on the movable plate 14, so that the height of the device after adjustment can be fixed, and then according to the change in the diameter of the barrel, the upper support plate 1 is manually pressed, and then the rotating plate 10 is rotated to rotate the first screw rod 2, and the mutual restriction between the convergence groove 13 and the movable plate 14 is utilized to drive the second screw rod 4 to rotate synchronously. At this time, the adjusting plate 5 will move in the opposite direction close to the upper support plate 1 and the lower support plate 3 respectively. As the distance between the adjusting plate 5 and the plate body becomes smaller, the first movable The lengths of the rod 6 and the second movable rod 7 remain unchanged, so they will bulge outward. The smaller the spacing between the adjustment plate 5 and the plate body, the greater the bulging length of the first movable rod 6 and the second movable rod 7, so that the diameter of the device is adjusted to match the diameter of the barrel, so that the device can be stably contacted and supported with the barrel. After the adjustment is completed, the bolt is inserted through the through hole 11, and the bolt is screwed into the positioning screw hole 9 at the nearest corresponding point, so that the rotating plate 10 can be fixed, thereby fixing the rotation position of the first screw rod 2 to avoid vibration force or other external force factors causing the first screw rod 2 to rotate twice. After all adjustments are completed, the blasting parts and the spacing devices can be cross-loaded into the barrel in batches. This is the working principle of the multifunctional interval charging control device for blasting operations.
