Description

Technical Field

[0001] This utility model relates to a target plate detonation testing device, and more particularly to a dual-target plate detonation testing device with controllable operating distance, belonging to the technical field of detonation testing devices. Background Technology

[0002] Detonation resistance is a crucial aspect of evaluating the protective effectiveness of materials. Typically, detonation resistance testing involves using a detonation testing device to establish a fixed distance between the simulated explosive and the test target plate. A counterweight is then used to stabilize the target plate, simulating a fixed load and providing fixation and support. However, traditional detonation testing devices are complex to assemble, can only test one target plate per test, resulting in low efficiency. Furthermore, the fixed distance between the simulated explosive and the target plate cannot be flexibly adjusted based on experimental phenomena, leading to increased testing costs and extended testing cycles. Utility Model Content

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a dual-target plate detonation testing device that can improve the efficiency and flexibility of detonation resistance testing, reduce testing costs, and has a controllable operating distance.

[0004] This utility model is achieved through the following technical solution: a dual-target plate detonation testing device with controllable operating distance, characterized in that: it includes a first target plate support frame, a second target plate support frame, a first target plate, a second target plate, and a connecting and fixing assembly. Both the first and second target plate support frames include square support plates with a square opening in the center. The four sides of the square opening are parallel to the four sides of the support plate. Support plates are fixed to the four sides of one of the support plate surfaces. Multiple bolt holes are provided on the four sides of the support plate. Corresponding bolt holes are also provided on the first and second target plates. The connecting and fixing assembly includes a threaded rod and two sets of nuts at both ends of the threaded rod, each set including two nuts. The first target plate... The first target plate support frame and the second target plate support frame are arranged parallel to each other vertically, with the support plate of the first target plate support frame facing upwards and the support plate of the second target plate support frame facing downwards. The first target plate support frame and the second target plate support frame are connected by multiple connecting and fixing components. The first target plate is located at the lower part of the first target plate support frame and is clamped and fixed to the first target plate support frame by two nuts at the upper end of the threaded rod of the connecting and fixing component. The second target plate is located at the upper part of the second target plate support frame and is clamped and fixed to the second target plate support frame by two nuts at the lower end of the threaded rod of the connecting and fixing component. The end of the threaded rod of the connecting and fixing component does not extend beyond the outer end of the support plate. The space between the first target plate and the second target plate is a detonation test space.

[0005] In use, the first and second target plates to be tested are fixed to the first and second target plate support frames respectively via connecting and fixing components. The positions of the first and second target plates can be adjusted by adjusting the positions of the nuts at both ends of the threaded rod of the connecting and fixing components to meet the required interaction distance between the simulated explosive and the target plate. The simulated explosive is placed at the diagonal intersection of the second target plate support frame. After adjusting the interaction distance between the simulated explosive and the first and second target plates, the detonation resistance test can be conducted. This invention allows for the simultaneous testing of two identical or dissimilar target plates in a single detonation test, significantly improving the efficiency of detonation resistance testing. The supporting plates on the first and second target plate support frames in this invention serve to support the testing device. The four supporting plates support the testing device, ensuring its overall stability.

[0006] Furthermore, to improve the structural strength of the target plate support frame and facilitate its processing and manufacturing, both the first and second target plate support frames are welded together from four angle steels or four channel steels, with the limbs of the angle steels or the wing plates of the channel steels serving as the supporting uprights.

[0007] Furthermore, the side length of the support plate is 300-1000mm.

[0008] Furthermore, the diameter of the threaded rod is 8–16 mm, and the length is 200–1000 mm.

[0009] Furthermore, bolt holes are provided at the four corners of the support plate and at the center of its four sides.

[0010] The beneficial effects of this invention are as follows: This invention connects two target plates simultaneously via a connecting and fixing assembly and two target plate support frames, enabling the simultaneous testing of two identical or dissimilar target plates in a single detonation test, significantly improving the efficiency of detonation testing. The connecting and fixing assembly, composed of a threaded rod and a nut assembly, reliably clamps and fixes the target plate under test, and allows for convenient adjustment of the target plate's position by rotating the nut, thereby adjusting the interaction distance between the simulated explosive and the target plate. This convenient adjustment of the target interaction distance allows test personnel to flexibly adjust the interaction distance based on the on-site testing conditions, improving the flexibility of target interaction distance adjustment. This invention has a simple structure, is reliable in use, easy to assemble, and convenient to transport. It can significantly reduce the difficulty and cost of test preparation for material detonation resistance performance testing. Attached Figure Description

[0024] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0025] As attached Figure 1 As shown, a dual-target plate detonation testing device with controllable operating distance includes a first target plate support frame 1, a second target plate support frame 4, a first target plate 2, a second target plate 5, and a connecting and fixing assembly 3.

[0026] The first target plate support frame 1 and the second target plate support frame 4 have the same structure and dimensions. For example... Figures 2-5As shown, taking the first target plate support frame as an example, it includes a square support plate 101 with a square opening in the middle. The four sides of the square opening are parallel to the four sides of the support plate 101. Each side of the support plate 101 has a certain width. The size of the square opening is determined according to the test design requirements. The support plate 101 can be made by cutting steel plates. Supporting uprights 102 are fixed to the four sides of one of the plate surfaces of the support plate 101. The supporting uprights 102 can also be made of steel plates and welded to the support plate 101. Multiple bolt holes 103 are provided on the four sides of the support plate 101. Preferably, bolt holes 103 are provided at the four corners and the middle of the four sides of the support plate 101. The first target plate 2 and the second target plate 5 also have bolt holes corresponding to the bolt holes 103 on the support plate 101.

[0027] like Figure 10 As shown, the connecting and fixing assembly 3 includes a threaded rod 301 and two sets of nuts. One end of the threaded rod 301 is threadedly connected to a set of nuts: a first nut 302 and a second nut 303. The other end of the threaded rod 301 is also threadedly connected to a set of nuts: a third nut 304 and a fourth nut 305.

[0028] As attached Figure 1 As shown, the first target plate support frame 1 and the second target plate support frame 4 are arranged parallel to each other vertically, with the support plate of the first target plate support frame 1 facing upwards and the support plate of the second target plate support frame 4 facing downwards. The first target plate 2 is located at the lower part of the first target plate support frame 1, and the second target plate 5 is located at the upper part of the second target plate support frame 4. The first target plate support frame 1 and the second target plate support frame 4 are connected by multiple connecting and fixing components 3. Specifically, the first target plate support frame 1 and the first target plate 2 are respectively bolted through their bolt holes to the upper end of the threaded rod of each connecting and fixing component 3 and located between the first nut 302 and the second nut 303, and the first target plate 2 is clamped and fixed to the first target plate support frame 1 by the first nut 302 and the second nut 303; the second target plate support frame 4 and the second target plate 5 are respectively bolted through their bolt holes to the lower end of the threaded rod of each connecting and fixing component 3 and located between the third nut 304 and the fourth nut 305, and the second target plate 5 is clamped and fixed to the second target plate support frame 4 by the third nut 304 and the fourth nut 305. The space between the first target plate 2 and the second target plate 5 is the detonation test space. The positions of the first target plate 2 and the second target plate 5 can be adjusted by adjusting the position of the nut on the threaded rod of the connecting and fixing assembly 3 to meet the target test distance requirements. In this invention, the length of the threaded rod of the connecting and fixing assembly 3 and the height of the support plate of the target plate support frame should be compatible. After the connecting and fixing assembly 3 is connected and fixed to the target plate and the target plate support frame, the end of the threaded rod of the connecting and fixing assembly 3 should not extend beyond the outer end of the support plate to ensure that the support plate of the lower second target plate support frame 4 can support the device and ensure the overall stability of the device.

[0029] like Figures 6-7 As shown, to improve the structural strength of the target plate support frame and facilitate its fabrication, the target plate support frame in this utility model can also be constructed by welding four angle steels together. One leg of each angle steel is welded together to form a square frame, with corresponding bolt holes on the frame side. The other leg of each angle steel serves as a support plate. Angle steel, as a standard profile, has high structural strength, meeting testing requirements, and its use in fabricating the target plate support frame is simple and convenient. Figures 8-9 As shown, the target plate support frame in this utility model can also be made by welding four channel steels. During welding, the webs of the four channel steels are located on the same plane and welded together to form a square frame. Corresponding bolt holes are set on the webs of the channel steels, and the two flanges of the channel steels serve as supporting uprights. As a standard profile, channel steel has high structural strength and large load-bearing capacity, which can meet the testing requirements, especially suitable for heavy loads. At the same time, it is simple and convenient to use it to make the target plate support frame.

[0030] This utility model can be used to manufacture testing devices of different specifications according to different testing conditions. For specific manufacturing methods, please refer to the following embodiments:

[0031] Example 1

The angle steel used is equilateral angle steel, with a side length of 30mm and a thickness of 6mm. The threaded rod of the connecting and fixing component 3 has a diameter of 8mm and a length of 200mm. The diameter of the bolt holes on the target plate support frame is 9mm. The first and second target plates are adapted to the target plate support frames.

[0033] Example 2

[0034] Both the first target plate support frame 2 and the second target plate support frame 4 are square, with a side length of 1000mm, and are made of welded angle steel, with a certain number of bolt holes. The angle steel used is equilateral angle steel, with a side length of 60mm and a thickness of 2mm. The threaded rod of the connecting and fixing component 3 has a diameter of 16mm and a length of 1000mm. The diameter of the bolt holes on the target plate support frame is 17mm. The first and second target plates are adapted to the target plate support frames.

[0035] When using this utility model:

[0036] (1) The first target plate support frame 1, the second target plate support frame 4, the first target plate 2, and the second target plate 5 are assembled using the connecting and fixing assembly 3 to obtain the following: Figure 1 The device shown is a dual-target plate detonation test device with controllable operating distance.

[0037] (2) Place the simulated explosive 7 at the intersection of the diagonals of the second target plate support frame 4, place plastic supports of different heights under it, and adjust the nuts of the corresponding connecting and fixing components 3 to control the action distance between the simulated explosive 7 and the first target plate 2 and the second target plate 5. After the adjustment is completed, the anti-detonation performance test can be carried out.

[0038] When using this invention for detonation resistance testing, the first target plate 2 and the second target plate 5 can be the same type or different types of target plates. This invention allows for the simultaneous testing of two target plates of the same or different types in a single detonation test, significantly improving the efficiency of detonation resistance testing. Test personnel can assemble and adjust the distance between the simulated explosive 7 and the target plate under test based on the on-site test results. The target test distance adjustment is highly flexible, further improving test efficiency.
