The side wall 19 of the test space 11 is provided with a plurality of second adjusting members 23, and the side wall 19 can be the first body 101 and the second body 102 described above. A top pressure plate 22 is arranged in the test space 11, and the top pressure plate 22 is connected to the first adjusting member 21.

[0054] The number of side pressure plates 24 is the same as the number of second adjusting members 23 and corresponds one to one. Multiple side pressure plates 24 are all arranged in the test space 11, and multiple side pressure plates 24 are respectively connected to multiple second adjusting members 23 in a one-to-one correspondence. Multiple side pressure plates 24 are arranged circumferentially along the test space 11, and at least two side pressure plates 24 among the multiple side pressure plates 24 are arranged opposite to each other. For example, there are two side pressure plates 24, and the two side pressure plates 24 are arranged circumferentially along the test space 11 and opposite to each other. Alternatively, there are three side pressure plates 24, and the three side pressure plates 24 are arranged circumferentially along the test space 11, and two of the side pressure plates 24 are arranged opposite to each other.

The height direction of the burst test box 100 is Figure 1 The Z direction shown is perpendicular to the height direction of the burst test box 100. Figure 1 By adjusting the positions of the top pressure plate 22 and the plurality of side pressure plates 24, the confining pressure blasting condition at a certain vertical depth can be simulated.

[0056] The detonating device 40 is arranged in the test space 11, and the monitoring device 61 is arranged on the outside of the blasting test box 100. The detonating control device 50, the detonating device 40, and the monitoring device 61 are all connected to the computer device 60 for communication. The detonating control device 50 is used to control the detonation of the detonating device 40, and the monitoring device 61 is used to monitor the parameter information around the blasting test box 100 during detonation. The computer device 60 is configured to obtain the password information of the detonating device 40 and send the password information to the detonating control device 50. The computer device 60 is also configured to determine the test parameter rules at different positions according to the parameter information.

[0057] When using the indoor blasting test system 200 proposed in the present application, the blasting test box 100 can be assembled first and placed on a flat ground, and the test piece loaded with explosives can be placed in the test space 11, and then the detonating device 40 can be set in the test space 11 and inserted into the explosives. The detonating wire of the detonating device 40 is connected to the detonating control device 50, and the detonating time and delay time of the detonating device 40 are set. The top pressure plate 22 and the side pressure plate 24 are respectively controlled by the first adjusting member 21 and the second adjusting member 23 so that the top pressure plate 22 and the side pressure plate 24 touch the test piece, and the decoding software, blasting software and motor control software of the computer device 60 are opened, the password information of the detonating device 40 is downloaded and sent to the detonating control device 50, and the software recording function is activated at the same time.

[0058] The detonation control device 50 is used to control the detonation of the detonator 40. During the explosion, the monitoring device 61 can monitor the parameter information around the blasting test box 100 during detonation. For example, the monitoring device 61 can monitor the vibration, air pressure and displacement values ​​around the blasting test box 100 during detonation, and the monitoring device 61 can transmit the monitored parameter information around the blasting test box 100 to the computer device 60. The computer device 60 can receive the parameter information transmitted by the monitoring device 61 and determine the vibration law, impact pressure law and displacement law of different positions according to the parameter information.

[0059] Specifically, by allowing the box body 10 to define a test space 11, when the explosives are detonated, the box body 10 can reduce the risk of damage to surrounding objects and personnel caused by fragments and airflow generated during the blasting, so that the blasting test box 100 has an excellent boundary constraint effect, and by driving the top pressure plate 22 to move along the height direction of the blasting test box 100 through the first adjustment member 21, the size of the upper load applied to the specimen can be adjusted, and by driving the multiple side pressure plates 24 to move in a direction perpendicular to the height direction of the blasting test box 100 through the multiple second adjustment members 23, the size of the lateral load applied to the specimen can be adjusted, thereby simulating the confining pressure blasting conditions at a certain vertical depth, so that the blasting test has a higher accuracy. Through the cooperation of the detonating device 40, the detonating control device 50, the computer device 60 and the monitoring device 61, the detonating device 40 can be controlled by the detonating control device 50, and the parameter information around the blasting test box 100 during detonation can be monitored by the monitoring device 61, and the test parameter rules at different positions can be determined by the computer device 60, such as: vibration, impact pressure and displacement rules, so as to reliably control the test and collect test data.

[0060] Therefore, the box body 10 can effectively block the fragments and airflow generated during the blasting to reduce the risk of damage to the surrounding area caused by the test. By adjusting the positions of the top pressure plate 22 and multiple side pressure plates 24, the confining pressure blasting conditions at a certain vertical depth can be simulated, which is beneficial to improving the accuracy of the test results. Through the cooperation of the detonator 40, the detonator control device 50, the computer device 60 and the monitoring device 61, the test can be reliably controlled and the test data can be collected, thereby improving the feasibility of indoor blasting tests.

[0061] In some embodiments of the present invention, Fig.11 As shown, the detonation control device 50 includes: a display module 51, a delay setting module 52, an information collection module 53, a safety detection module 54 and a blasting control module 55.

[0062] Among them, the display module 51, the delay setting module 52, the information collection module 53, the safety detection module 54 and the blasting control module 55 can be integrated, wherein the display module 51 can be used to display various information of the detonation control device 50. The delay setting module 52 can set the detonation delay time of the detonation device 40 according to the designed blasting scheme. The information collection module 53 can collect and verify the password file of the detonation device 40, and the password file is obtained by the computer device 60 and transmitted to the information collection module 53 of the detonation control device 50 for collection by the information collection module 53. The safety detection module 54 can be used to check whether the detonation device 40 can work normally. For example, the detonation device 40 can be constructed as an electronic detonator, and the safety detection module 54 can be used to monitor whether the electronic control module 42 of the electronic detonator can work normally. The blasting control module 55 can be used to issue a blasting start command to the detonation device 40.

[0063] Such a configuration enables the detonation control device 50 to integrate multiple functions such as display, delay setting, information collection, safety monitoring, and blasting control, thereby ensuring the smooth progress of the test and being conducive to improving the reliability of the indoor blasting test system 200.

[0064] In some embodiments of the present invention, the monitoring device 61 includes: a vibration monitoring component, an air pressure monitoring component, and a displacement monitoring component. Among them, the vibration monitoring component is used to monitor the vibration around the blasting test box 100 during detonation, the air pressure monitoring component is used to monitor the air pressure around the blasting test box 100 during detonation, and the displacement monitoring component is used to monitor the displacement around the blasting test box 100 during detonation. Such a setting enables the monitoring device 61 to monitor the vibration, air pressure and displacement values ​​around the blasting test box 100 during detonation, so that the computer device 60 can determine the vibration law, impact pressure law and displacement law of different positions according to the parameter information monitored by the monitoring device 61, so as to accurately obtain the test results.

[0065] In some embodiments of the present invention, Fig.10 As shown, the detonator 40 is constructed as an electronic detonator, wherein the electronic detonator may include a pipe plug 41, an electronic control module 42, an ignition powder part 43 and a main charge part 44. The pipe plug 41 is used to prevent the internal components from falling out, and the electronic control module 42 is used to receive the command of the detonation control device 50 and discharge to ignite the ignition powder of the ignition powder part 43. The ignition powder is used to ignite the main charge of the main charge part 44, and the main charge is used to detonate the low-sensitivity explosive in the test piece. By constructing the detonator 40 as an electronic detonator, it is possible to reliably receive the command of the detonation control device 50 and detonate the explosive in the test piece, so as to reliably perform the blasting test, reduce the risk of failing to detonate the explosive, and help improve the reliability of the indoor blasting test system 200.

[0066] In some embodiments of the present invention, Figure 2 As shown, a buffer pad 25 is fixedly disposed on the surface of the top pressure plate 22 facing away from the top wall 18 and / or on the surface of the side pressure plate 24 facing away from the side wall 19 .

[0067] Among them, a buffer pad 25 is fixedly provided on the surface of the top pressure plate 22 away from the top wall 18, or a plurality of side pressure plates 24 are fixedly provided with buffer pads 25 on their surfaces away from the side walls 19, or a buffer pad 25 is fixedly provided on the surface of the top pressure plate 22 away from the top wall 18, and a plurality of side pressure plates 24 are fixedly provided with buffer pads 25 on their surfaces away from the side walls 19. The buffer pad 25 may be, but is not limited to, a rubber pad, a resin pad, etc. By fixing the buffer pad 25 on the surface of the top pressure plate 22 away from the top wall 18, the wear between the top pressure plate 22 and the specimen can be reduced, and by fixing the buffer pad 25 on the surface of the side pressure plate 24 away from the side wall 19, the wear between the side pressure plate 24 and the specimen can be reduced, and the probability of punching when the explosive explodes can be reduced.

[0068] As some embodiments of the present application, Figure 3 and Figure 4 As shown, the side pressure plate 24 is a flat plate structure or an arc-shaped structure.

[0069] Among them, if the side pressure plate 24 is a flat plate structure, the surface of the side pressure plate 24 away from the top wall 18 is a plane; if the side pressure plate 24 is an arc-shaped structure, the surface of the side pressure plate 24 away from the top wall 18 is an arc-shaped surface. The side pressure plate 24 with a flat plate structure or the side pressure plate 24 with an arc-shaped structure can be selected according to the outer contour of the specimen so that the side pressure plate 24 is adapted to the specimen to reliably apply lateral load to the specimen.

[0070] In some embodiments of the present invention, Figure 2 and Figure 6As shown, a first threaded hole is formed on the top wall 18 of the test space 11, and the first threaded hole is connected to the test space 11.

Such a setting can reduce the risk of the side pressure plate 24 rotating with the second adjusting member 23 during the movement, and can reduce the risk of the side pressure plate 24 colliding with the explosive due to the rotation, which is conducive to improving the safety of the indoor explosion test system 200.

As some embodiments of the present application, the telescopic folding rod assembly 33 includes a plurality of telescopic folding rods 331, and the plurality of telescopic folding rods 331 are connected in sequence. Taking the telescopic folding rod assembly 33 as an example, which includes three telescopic folding rods 331, one end of the first telescopic folding rod 331 is connected to the side wall 19 of the test space 11, and the other end of the first telescopic folding rod 331 is rotatably connected to one end of the second telescopic folding rod 331 (for example, through but not limited to rivets or pivot shafts), and the other end of the second telescopic folding rod 331 is rotatably connected to one end of the third telescopic folding rod 331 (for example, through but not limited to rivets or pivot shafts), and the other end of the third telescopic folding rod 331 is rotatably provided on the connecting seat 32 (for example, through but not limited to bolts, rivets, pivot shafts, etc., rotatably provided on the connecting seat 32).

The through hole 15 is used to accommodate the detonating wire, that is, the detonating wire can pass through the through hole 15 to extend out of the test space 11. By forming the through hole 15 in the box body 10, the detonating wire can be led out of the test space 11, so that part of the structure of the detonating wire is located outside the box body 10, thereby igniting the detonating wire is convenient and the difficulty of the test can be reduced.

[0089] As some embodiments of the present application, Figure 1 and Figure 2 As shown, the top wall 18 of the test space 11 is formed with a through hole 15 .

Specifically, the fixed bottom plate 70 is arranged at the lower end of the box body 10 and is connected to the box body 10. The fixed bottom plate 70 covers the open end of the test space 11. As some embodiments of the present application, a positioning groove 13 is formed on the inner side of the bottom of the box body 10, and the fixed bottom plate 70 has a protruding positioning buckle 72, and the positioning buckle 72 can be used to cooperate with the positioning slot 13 to firmly install the fixed bottom plate 70 on the box body 10.

[0093] The clamping structure 80 is disposed in the test space 11, and the clamping structure 80 is fixed to the fixed bottom plate 70, that is, the fixed bottom plate 70 provides an installation position for the clamping structure 80. The clamping structure 80 is located on the side of the top pressure plate 22 away from the top wall 18 of the test space 11. In short, the clamping structure 80 is located below the top pressure plate 22. The clamping structure 80 is used to fix the test piece, for example, the clamping structure 80 can clamp and fix the test piece.

[0094] By providing the fixed bottom plate 70, the open end of the test space 11 can be covered to make the test space 11 a closed space, which can reduce the risk of damage to surrounding objects and personnel caused by fragments and airflow generated during explosion, and can also provide an installation position for the clamping structure 80. By providing the clamping structure 80, the test piece can be fixed, thereby reducing the probability of the test piece moving, so that the test piece is accurately located at a preset position, which is conducive to improving the test accuracy and the reliability of the explosion test box 100.

The second plug posts 83 of each sub-clamping part 81 are suitable for being inserted into the corresponding mounting holes 71 so that the clamping structure 80 is fixed to the fixed base plate 70.

[0097] The driving structure 84 is arranged on the limit clamping seat 82, and the driving structure 84 is connected to the push plate 85. The driving structure 84 is used to drive the push plate 85 to move. By making the driving structures 84 of the multiple sub-clamping parts 81 drive the corresponding push plates 85 to move toward the test piece, the push plates 85 of the multiple sub-clamping parts 81 can contact the test piece to fix the test piece. As some embodiments of the present application, the driving structure 84 may include a driving member 841 and a movable push rod 842. The movable push rod 842 is connected between the driving member 841 and the push plate 85. The driving member 841 can drive the movable push rod 842 to move so that the movable push rod 842 drives the push plate 85 to move. The driving member 841 includes a push rod knob 8411.

By driving the push plate 85 to move through the driving structure 84, the position of the push plate 85 can be easily controlled, so that the test piece can be stably fixed by multiple push plates 85, reducing the probability of movement of the test piece, so that the test piece can be accurately placed in the preset position, which is beneficial to improving the test accuracy. Moreover, this can be applicable to test pieces with different structures and has a wide range of applications.

[0099] In some embodiments of the present invention, Fig. 9 As shown, the limiting clamping seat 82 is formed with a guide groove 821 , a portion of the push plate 85 is installed in the guide groove 821 , and the driving structure 84 is used to drive the push plate 85 to move along the guide groove 821 .

[0101] By forming a guide groove 821 on the limit clamp 82 and partially installing the push plate 85 in the guide groove 821, the movement of the push plate 85 can be guided by the guide groove 821, thereby reducing the risk of the push plate 85 being displaced in the moving direction, thereby reducing the probability of the push plate 85 getting stuck, allowing the push plate 85 to accurately contact the specimen and stably fix the specimen, which is conducive to the smooth completion of the test.
