Description

Technical Field

[0001] The invention relates to the technical field of pyrotechnic device testing, and in particular to a pyrotechnic device assembly and testing protection device. Background Art

[0002] Reliable starting of solid rocket engines requires a high-quality ignition device. Ignition devices come in various forms, but ignition cartridges are widely used as important components. As energetic pyrotechnics, ignition cartridges have high energy density, small structural dimensions, and large instantaneous energy release. Because the internal pyrotechnics are relatively sensitive, they can cause chemical reactions such as combustion and explosion under the action of relatively small initial impulse energy from the outside world (such as mechanical energy, thermal energy, or electrostatic energy). At present, the traditional manual operation mode is used in the assembly and testing process of ignition cartridges, and this production mode has great safety hazards.

[0003] Most of the existing safety protection devices for explosives are steel plate structures. The main body is made of steel plate, and organic glass is embedded in the observation hole. The overall structure is relatively large. Although this type of protection device can protect the safety of personnel and equipment, it has the following shortcomings: The existing protection device structure is bulky. Because the main structure of the protection device is mostly made of steel plate, the overall weight is very large, difficult to move and inconvenient to carry. The existing protection device only has organic glass embedded in the observation hole, and the other parts are steel plates and opaque, resulting in a small observation field, which is inconvenient to operate the product. Summary of the invention

[0004] Based on the above technical problems, the present invention proposes a protective device for assembling and testing pyrotechnics to solve the problems that the existing protective devices are inconvenient to carry, have a small observation field of view, and are inconvenient to operate. This reduces the danger to a certain extent, and ensures the personal safety of front-line production test personnel.

[0005] In order to solve the above technical problems, one of the purposes of the present invention is to provide a pyrotechnic assembly and test protection device, comprising: a protection bracket 1, a protection glass fixing bolt assembly 2, a shaft bolt assembly 4, a base fixing bolt assembly 5, a base 6, a shaft 7 and a protection glass 8,

[0006] Through holes are added to the protective bracket 1 and the protective glass 8, and are fixed by the protective glass fixing bolt assembly 2;

[0007] The protective bracket 1 is fixedly connected to the base 6 via a rotating shaft 7 and is locked using a rotating shaft bolt assembly 4;

[0008] Through holes are added on the base 6 and the table top, and are fixed by base fixing bolts 5 .

[0009] Furthermore, the protection device also includes a limiting device 9, which adjusts the inclination locking of the protection bracket 1 and the base 6 through the limiting bolt assembly 3 to achieve a limiting function.

[0010] Furthermore, the protective baffle of the protective device is made of organic glass with a thickness of 10 mm.

[0011] Furthermore, the protective bracket of the device is made of No. 20 steel material, which is convenient for welding processing of the protective bracket.

[0012] Furthermore, the fixed base of the device is made of No. 20 steel material, which facilitates the welding process of the rotating fixed supports on both sides of the fixed base.

[0013] Furthermore, the protective bracket 1 has an observation window at the bottom, which makes it easier for the operator to observe the operation process.

[0014] The above one or more technical solutions of the present invention have at least one or more of the following technical effects:

[0015] The pyrotechnic assembly and testing protection device provided by the present invention effectively solves the problems of the traditional protection device being unable to adjust, having a small observation window and poor field of view;

[0016] The pyrotechnic assembly and testing protection device provided by the present invention optimizes the structure of the traditional protection device and reduces the overall mass of the protection device to a great extent.

[0017] The protective device of the present invention physically isolates people from sensitive pyrotechnics, reduces the danger to a certain extent, and achieves the purpose of ensuring the personal safety of front-line production test personnel. The inclination angle between the protective bracket and the desktop can be adjusted according to the height and sitting posture of different production test personnel, which is convenient for the operator to adjust the field of view.

[0025] The present invention provides a pyrotechnic assembly and testing protection device, which is mainly used to separate people from pyrotechnics during assembly and testing of pyrotechnics. Once the pyrotechnics ignite accidentally, the device can protect the upper torso of the front-line personnel, especially the face. The device can adjust the inclination angle between the protection bracket and the desktop according to the height and sitting posture of different production testers, which is convenient for the operator to adjust the field of vision. At the same time, when the pyrotechnic assembly and testing protection device is idle, it can be unfolded at a large angle and placed flat on the desktop without occupying the operating space of other processes.

[0026] The pyrotechnic assembly and testing protection device uses manpower to flip the protection bracket to open and adjust the protection device to achieve better protection and vision. At the same time, the device can be locked in the folded and extended position and has a limit function to prevent or reduce the damage caused by accidental ignition of pyrotechnics.

[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in combination with the embodiments of the present invention and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the obtained embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0028] The invention discloses a protective device structure for assembling and testing explosives. Figure 1 As shown, the protective device is composed of a protective bracket 1, a protective glass fixing bolt assembly 2, a limiting bolt assembly 3, a rotating shaft bolt assembly 4, a base fixing bolt assembly 5, a base 6, a rotating shaft 7, a protective glass 8 and a limiting device 9. Through holes are added on the protective bracket 1 and the protective glass 8, and are fixed by the protective glass fixing bolt assembly 2; the protective bracket 1 and the base 6 are fixedly connected by the rotating shaft 7 and locked by the rotating shaft bolt assembly 4; a through hole is added on the base 6 and the desktop, and is fixed by the base fixing bolt 5. Through holes are added on the limiting part of the protective bracket 1 and the base 6, and are fixed by the limiting bolt assembly 3.

[0029] The protective bracket solution is used to replace the protective cover to avoid forming a closed space as much as possible, dissipate the explosion energy caused by accidental ignition, and reduce the danger. At the same time, the openings on both sides of the protective device are enlarged, making it easier for operators to evacuate the dangerous area in time when they find danger, ensuring personal safety.

[0030] The bottom observation window of the protective device is as follows Figure 3 As shown, an observation window is added to the bottom of the protective device. The protective bracket has an observation window at the bottom, which makes it easier for operators to observe the operation process. It can also adapt to the operation observation of operators of different heights in different sitting postures.

[0031] The protective device can adjust the inclination angle. Figure 4 As shown in the figure, the inclination angle of the protective device can be adjusted according to the operation and observation habits of different operators, and then fixed by tightening bolts. The protective bracket and the fixed base are fixed by a rotating shaft to meet the rigidity requirements. After use, the protective device can be unfolded and laid flat at a large angle to avoid taking up too much space and save operating space on the desktop.

[0032] Schematic diagram of protective device limit device Figure 5 As shown in the figure, the inclination adjustment of the protective device is fixed by the fastening bolts. Once the pyrotechnics ignite, the protective baffle will be subjected to a certain force and the limit bolts will be subjected to shear force. The limit function of the protective device is mainly to prevent the limit bolts from accidentally falling off or the protective bracket from being not fully fixed due to insufficient rigidity, resulting in extreme rotation and accidental injury to the operator.

[0033] The inclination locking and installation form of the protective bracket, base, and protective glass baffle of the pyrotechnic assembly and test protection device follow the principle of simplicity and reliability, ensuring the feasibility of the overall plan of the pyrotechnic assembly and test protection device.

[0034] The protective bracket is connected to the base by a rotating shaft, the fixed base is fixed to the desktop by bolts, and the inclination of the protective bracket is secured by fastening bolts. Figure 6 shown.

[0035] The protective baffle of the protective device is made of 10mm thick organic glass. After analysis, the use of organic glass plate as a protective baffle has good light transmittance and can ensure a good field of vision during operation. The thickness of the organic glass is 10mm, which can effectively reduce the damage to the operator caused by accidental ignition of pyrotechnics. The protective bracket of this device is made of No. 20 steel material for welding and processing. This material is a high-quality low-carbon carbon steel with good toughness, plasticity and weldability, which is convenient for the welding of the protective bracket. The fixed base of this device is made of No. 20 steel material for welding and processing. The material has good toughness, plasticity and welding properties, which is convenient for the welding of the rotating fixed supports on both sides of the fixed base.

[0036] The rotation limit function of the protective bracket and the base of the protective device is realized by using a ratchet mechanism instead of a limit bolt to achieve one-way rotation locking. This structure has been manufactured into actual products and verified by the pill box ignition impact test.

[0037] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
