DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0047] like Figure 1 As shown, the plate anti-explosion impact performance testing equipment includes: a base 1, a plate 2, a slide 3, and a driving mechanism 4. A platform 7 is installed at the center of the base 1. The platform 7 is composed of a top plate and a main body and is used to place explosives. The top plate is made of a 5cm thick titanium alloy plate with high strength. When the explosive on the top explodes, it can ensure that the damage to itself is small. The top plate of the platform 7 is connected to the main body by a reinforcing rod bolt, which can be easily replaced after damage. There are four slides 3, and the shape of the slides 3 is as follows: Figure 1 As shown, four slideways 3 are equidistantly installed on the upper surface of the base 1 along the circumferential direction, a driving mechanism 4 is installed on the base 1, there are four plates 2, and the four plates 2 are equidistantly installed on the driving mechanism 4 along the circumferential direction. The driving mechanism 4 can be controlled to make the four plates 2 approach or move away from the center of the base 1 synchronously, thereby changing the distance between the plates 2 and the explosion center.

[0048] like Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the driving mechanism 4 includes: a moving seat 41, a slider 42, a connecting rod 43, a fixed seat 44, a first limiting groove 45, a second limiting groove 46 and a limiting block 47. There are four moving seats 41, which are respectively installed on the top of the four slideways 3. There are four sliders 42, which are respectively installed on the lower surface of the four moving seats 41, and the four sliders 42 are respectively slidably installed in the four slideways 3. The sliders 42 slide in the slideways 3 to enable the moving seats 41 to move synchronously. There are four connecting rods 43, which are distributed in a square shape, and two adjacent connecting rods 43 are staggered up and down to avoid mutual interference. The two ends of the connecting rod 43 slide through two adjacent moving seats 41 respectively. When one of the moving seats 41 approaches the platform 7 or moves away from the platform 7, the square surrounded by the four connecting rods 43 will gradually shrink or expand, and the remaining three moving seats 41 can move synchronously. There are four fixed seats 44, which are respectively installed on the base 1 at equal intervals along the circumferential direction. The first limiting groove 45 is provided on the fixed seat 44, and the linkage rod 43 passes through the first limiting groove 45. The linkage rod 43 can move in the first limiting groove 45. The second limiting groove 46 is provided on the fixed seat 44. The limiting block 47 is installed on the linkage rod 43. The limiting block 47 is slidably installed in the second limiting groove 46. The limiting block 47 can move in the second limiting groove 46. The movement of the linkage rod 43 can be limited by the limiting cooperation of the first limiting groove 45 and the second limiting groove 46, so as to ensure that the linkage rod 43 can only move in the direction away from the platform 7 or close to the platform 7. The four plates 2 are respectively installed on the top of the four moving seats 41, so as to ensure that the plates 2 move synchronously.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a power mechanism 5 is installed on the base 1, and the power mechanism 5 can drive one of the moving seats 41 to move. The power mechanism 5 includes: a first screw 51, a rotating seat 52, a blind groove 53 and a protrusion 54. One end of the first screw 51 is installed on one of the sliders 42, and the other end of the first screw 51 passes through the outer wall of the base 1. The rotating seat 52 is rotatably installed on the base 1. The inner cavity of the rotating seat 52 is provided with an internal thread that matches the external thread of the first screw 51, and the rotating seat 52 is threadedly connected with the first screw 51. When the rotating seat 52 is rotated, the first screw 51 can move along its own axial direction. The blind groove 53 is opened on the first screw 51, and the protrusion 54 is installed on the base 1, and the protrusion 54 is slidably embedded in the blind groove 53. The mutual limiting cooperation of the protrusion 54 and the blind groove 53 can prevent the first screw 51 from rotating, thereby ensuring the stable movement of the first screw 51.

[0050] The actual use method of the above structure is as follows: place the device in an open field, and place explosives on the upper surface of the platform 7. Rotate the rotating seat 52 to move the first screw 51 toward the platform 7 along its axial direction, and then push the slider 42 connected to it to move together, and use the cooperation of the four connecting rods 43 to move the other three sliders 42 together. At this time, the four moving seats 41 drive the plate to move toward the platform 7 together. When the distance between the plate 2 and the platform 7 is the planned distance, stop rotating the rotating seat 52. Then the personnel evacuate the scene and remotely start the explosives.

[0051] The device can freely adjust the distance between the plate and the explosion center, is easy to operate, and can ensure that the plates 2 in all directions move synchronously, so that the distance between each plate and the explosion center remains equal. The first limiting groove 45 cooperates with the limiting action of the linkage rod 43 and the second limiting groove 46 cooperates with the limiting block 47 to ensure the stable sliding of the linkage rod 43; the slideway 3 limits the position of the slider 42 to ensure the stable directional movement of the moving seat 41 to avoid deviation from the direction.

[0052] like Figure 1 , Figure 8 , Fig. 9 , Fig.10 and Fig.12As shown, the plate 2 is mounted on the top of the moving seat 41 through the clamping mechanism 6, and the clamping mechanism 6 is controlled to automatically clamp the plate 2 in the center relative to the moving seat 41. The clamping mechanism 6 includes: a bracket 61, a through slot 62, a clamping plate 63, a slide bar 64, a driving slot 65, a second screw 66 and a limit rod 67. The bracket 61 is fixedly mounted on the top of the moving seat 41, and there are four through slots 62, and the four through slots 62 are evenly divided into two groups. The two groups of through slots 62 are symmetrically mounted on the bracket 61, and there are two clamping plates 63, and the two clamping plates 63 are symmetrically mounted on the bracket 61. The plate 2 is located between the bracket 61 and the clamping plates 63. When the clamping plates 63 move toward the direction of the bracket 61, the plate 2 can be clamped. There are four slide bars 64, which are evenly divided into two groups. The two groups of slide bars 64 are respectively installed at the bottom ends of the two clamping plates 63. The four slide bars 64 are respectively slidably installed in the four through slots 62, wherein the two groups of through slots 62 are respectively tilted outwardly from the bracket 61 in the direction away from the bracket 61. When the clamping plates 63 move toward the bracket 61, the two clamping plates 63 can move toward the bracket 61 and approach each other at the same time by the cooperation of the slide bars 64 and the through slots 62. In addition, the clamping plates 63 are L-shaped when viewed from above, which can synchronously limit the side wall of the plate 2. The second screw rod 66 is rotatably installed on the bracket 61, and the driving slot 65 is threadedly connected to the second screw rod 66. When the second screw rod 66 rotates, the driving slot 65 can move along the axial direction of the second screw rod 66, wherein the bottom end of the slide bar 64 passes through the driving slot 65. When the driving slot 65 moves, the slide bar 64 and the clamping plates 63 can move along the through slot 62. There are two limit rods 67, which are respectively installed on the bracket 61. The driving groove 65 is slidably connected with the limit rods 67. The limit rods 67 and the second screw rod 66 are arranged in parallel. The limit rods 67 can be used to limit the driving groove 65 to ensure that the driving groove 65 can only move stably along the axial direction of the limit rods 67 and the second screw rod 66 to prevent the driving groove 65 from rotating.

[0053] It is worth noting that the plates 2 used in this embodiment are all cut into the same size according to the size of the bracket 61 to ensure that they can be stably clamped in the center.

[0054] The actual use method of the above structure is as follows: place the plate 2 between the clamp 63 and the bracket 61, rotate the second screw 66 to move the drive slot 65 toward the bracket 61, and use the through slot 62 to limit the slide rod 64 to make the two clamps 63 move synchronously toward the bracket 61. At the same time, the two clamps 63 approach each other so that the plate 2 is clamped in the center.

[0055] This structure can realize the rapid centering clamping of the plate 2, and by fixing the bottom of the plate 2, ensure that the upper half of the plate 2 is completely exposed, and prevent the situation of affecting other parts of the equipment when receiving the explosion impact. The limit rod 67 is used to limit the driving groove 65 to ensure that the driving groove 65 moves stably and avoids deviation.

[0056] When using the above structure in this embodiment to conduct an explosion test, the explosive is placed on the upper surface of the platform 7. It should be ensured that in the above structure of this embodiment, except for the plate 2, it is completely located below the platform 7, so that when conducting the explosion impact test, only the surface of the plate 2 is affected, and other components are not affected. However, in practice, the explosion center is far away from the plate. In addition to affecting the plate 2, the explosion is also likely to impact the clamping mechanism 6 and other components in the lower part of the plate. If the height of the platform 7 is insufficient, it is still easy to affect the subsequent use of the equipment. In order to be able to adjust the height of the platform 7 in a targeted manner, the following solution is proposed: Reference Figure 1 , Figure 4 , Figure 5 and Fig.11 As shown, a linkage mechanism is also installed on the base 1, and the linkage mechanism can be controlled to drive the platform 7 to rise and fall. The linkage mechanism includes: a cavity 101, a rotating table 10, a rotating drum 12, a rod groove 13, a rod body 14, a first gear 8 and a second gear 902. The cavity 101 is opened on the lower surface of the base 1, and the rotating table 10 is rotatably installed on the lower surface of the base 1, and the rotating table 10 is located in the cavity 101, ensuring that the base 1 is placed on the ground and the rotating table 10 does not protrude from the lower surface of the base 1. The rotating drum 12 is installed on the rotating table 10, and the two can rotate synchronously. The rotating drum 12 is provided with an external thread, and the inner cavity of the platform 7 is provided with an internal thread adapted to the external thread of the rotating drum 12. The rotating drum 12 passes through the base 1 and is connected to the inner cavity thread of the platform 7. There are several rod grooves 13, which are equidistantly arranged on the lower surface of the platform 7 along the circumferential direction. There are several rod bodies 14, which are respectively installed on the base 1 along the circumferential direction, and the top of the rod body 14 is slidably installed in the rod groove 13. When the platform 7 moves up and down, relative sliding will occur between the rod groove 13 and the rod body 14. By using the cooperation of the two, it can be ensured that the platform 7 is only lifted and lowered without self-rotation. A first gear 8 is installed on the rotating seat 52, and a second gear 902 is rotatably installed on the base 1. The second gear 902 is meshed and connected with the first gear 8 to ensure that when the rotating seat 52 is rotated, the first gear 8 and the second gear 902 can rotate synchronously. One end of the rotating shaft 901 is installed on the second gear 902, and the rotating shaft 901 is installed in the cavity 101 through a bearing seat. The other end of the rotating shaft 901 is installed with a first bevel gear 9. A second bevel gear 11 is installed on the rotating table 10, and the second bevel gear 11 is meshed and connected with the first bevel gear 9. When the first bevel gear 9 rotates, it can drive the second bevel gear 11 to rotate synchronously.

[0057] The actual usage method of the above structure is as follows: while rotating the rotating seat 52 to drive each plate 2 to move toward the platform 7, the first gear 8 will rotate synchronously, and the second gear 902, the rotating shaft 901 and the first bevel gear 9 will also rotate synchronously, thereby driving the second bevel gear 11 and the rotating table 10 to rotate, and at the same time utilizing the action of the rotating drum 12 to move the platform 7 downward; conversely, when the reverse rotation 52 is used to move each plate 2 away from the platform 7, the platform 7 can be raised to raise the height of the explosion center, thereby preventing the explosion point from being too low to impact the rest of the equipment.

[0058] In use, the structure can flexibly adjust the height of the explosion center according to actual conditions to protect the equipment components other than the plate 2. At the same time, the platform 7 can be automatically adjusted when the distance of the plate 2 is adjusted, without additional operation, saving operation steps and easy operation. In addition, the platform 7 is prevented from rotating by itself by the cooperation of the rod groove 13 and the rod body 14. The arrangement of multiple rod bodies 14 and rod grooves 13 makes the force on the platform 7 more stable.

[0059] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
