Description

Technical Field

[0001] The utility model relates to the technical field of initiating explosive device safety, in particular to a disassembly tooling and a disassembly system for misfired initiating explosive devices. Background Technique

[0002] An initiating explosive device is a general term for disposable components, devices, and systems that, after receiving a firing instruction, use a small amount of energy to stimulate the sensitive agent contained therein to generate combustion or explosion, and use its combustion flame, explosion shock wave, and high-pressure gas to achieve predetermined functions such as ignition, initiation, and work. Initiating explosive devices are widely used in the fields of weapons and ammunition, aerospace, and petroleum and civil explosives, and are often used as the initial energy source.

[0003] When an initiating explosive device is stimulated by an external stimulus source and fails to fire, at this time, the initiating explosive device is in an extremely unstable state, and disassembly at this time may cause the initiating explosive device to accidentally fire. Therefore, disassembly cannot be carried out without a special disassembly tooling. For safety reasons, the current practice is mostly to destroy it on the spot. However, this approach means losing the opportunity to analyze product defects and further improve quality. Especially for those initiating explosive devices or weapons and ammunition with higher value, if the misfired initiating explosive device can be safely removed, its warhead and other components may be recycled. For this reason, we propose a disassembly tooling and a disassembly system for misfired initiating explosive devices. Content of the Utility Model

[0004] The utility model aims to provide a disassembly tooling and a disassembly system for misfired initiating explosive devices, which can disassemble misfired initiating explosive devices at a safe distance and analyze the reasons for misfiring of the initiating explosive devices, providing a basis for subsequent improvement and quality control of the products.

[0005] For this reason, the technical solution adopted by the utility model is as follows:

[0006] A disassembly tooling for misfired initiating explosive devices includes:

[0007] An explosion-proof plug, an internal disassembly handle is installed in the explosion-proof plug, a disassembly part is detachably installed at the central position of one end of the disassembly handle, and a protrusion is fixedly connected to the side wall of the disassembly part;

[0008] A slide rail is detachably installed on the side wall of the explosion-proof plug, a front positioning plate is slidably connected to the slide rail, a planetary reducer is installed on the front positioning plate, a motor is installed on one side of the planetary reducer, and a three-jaw chuck is installed on the other side of the planetary reducer. The disassembly handle passes through the central position of the explosion-proof plug and is coaxially connected to the three-jaw chuck;

[0009] A rear positioning plate is installed on the side wall of the motor and is also slidably connected to the slide rail.

[0010] Based on the above technical solution, its working principle and the resulting technical effects are as follows:

[0011] During actual use, first assemble the part to be disassembled with the disassembly handle by tightening the compression cap, then assemble the disassembly handle with the explosion-proof plug, so that the rotary handle on the disassembly handle passes through the second bearing installed in the stepped hole. Then insert the part of the initiator to be disassembled into the explosion-proof plug through the opening, rotate the positioning bolt to clamp and fix the initiator and position it at the middle position. Then, snap the protrusion on the disassembled part into the assembly hole of the initiator to be disassembled, and ensure that the spring is in a compressed state at this time. Pass the slide rail through the first guiding hole of the front motor positioning plate and the second guiding hole of the rear motor positioning plate in sequence to realize the support and guidance of the motor and the planetary reducer. Then, use a three-jaw chuck to clamp the rotary handle at an appropriate position to ensure the coaxial connection between the planetary reducer and the disassembly handle. Then connect the driver to the battery, turn on the safety switch, and you can start the remote control disassembly of the misfired initiator. After the disassembly is completed, you can observe through the observation window whether the initiator has been safely removed, so as to facilitate the realization of the entire process of remotely controlling the safe disassembly of the misfired initiator. Then analyze the cause of misfire of the initiator based on the disassembled misfired initiator.

[0012] In a preferred embodiment of the present utility model, it can be further configured that: the cross-sectional shape of the explosion-proof plug is circular, one side of which is provided with an opening, and a positioning component is installed at one end of the explosion-proof plug close to the opening.

[0013] In a preferred embodiment of the present utility model, it can be further configured that: the positioning component includes a mounting hole opened on the side wall of the explosion-proof plug and a positioning bolt threadedly connected in the mounting hole;

[0014] Or the positioning component includes a three-jaw chuck or a four-jaw chuck fixed at one end of the explosion-proof plug.

[0015] In a preferred embodiment of the present utility model, it can be further configured that: a stepped groove is clamped on the outer side wall of the disassembly handle, and a first bearing is installed at the stepped groove, and the disassembly handle is rotatably connected to the explosion-proof plug through the first bearing.

[0023] Explanations for the nouns, connecting words or adjectives involved in the above technical solutions are as follows:

[0024] Fixed connection means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0025] (1) Detachable connection uses screws, splines, wedge pins, etc. to fix the parts together. This connection method can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be tightened properly.

[0026] (2) Non-detachable connection mainly refers to welding, riveting and mortise fitting, etc. Since it needs to be forged, sawed or oxy-cut to be disassembled during maintenance or replacement, the spare parts generally cannot be used twice. At the same time, during connection, attention should be paid to process quality, technical inspection and remedial measures (such as correction, polishing, etc.);

[0027] Movable connection means that after the parts or components are fixed, there is a relative movement connection.

[0028] The above technical solutions of the present utility model have the following beneficial technical effects:

[0029] 1. Through the mutual cooperation of the explosion-proof plug, disassembly handle, and disassembly part structure provided by the present utility model, it is possible to disassemble misfired pyrotechnics at a safe distance and analyze the reasons for misfiring of pyrotechnics, providing a basis for the subsequent improvement and quality control of products.

[0030] 2. The present utility model adopts a remote control method for operation to maximize the safety of operators and avoid explosion during disassembly, causing harm to the human body.

[0031] 3. The whole of the present utility model can be self-powered by a storage battery, is convenient to carry, can provide power support in sparsely populated test sites, avoids unnecessary transportation and storage, and reduces the risks existing in this process. Description of the Drawings

Detailed implementation manners

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without making creative efforts belong to the scope of protection of the present disclosure. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0043] According to the concept of the present application, an embodiment of a disassembly tool for a misfired explosive device for safely disassembling a misfired explosive 18 will be described herein in combination with Figures 1 to 8 Specifically, the disassembly tool for the misfired explosive device is configured as an integral structure, which has three components: an explosion-proof plug 1, a slide rail 10, and a rear positioning plate 9. Through the mutual cooperation of the structures such as the explosion-proof plug 1, the disassembly handle 2, and the disassembly part 12, the misfired explosive 18 can be disassembled at a safe distance, and the cause of misfire of the explosive can be analyzed, providing a basis for the subsequent improvement and quality control of the product. Moreover, the operation is carried out in a remote control manner to maximize the protection of the safety of the operator. At the same time, it can be self-powered by a storage battery 15, which is convenient to carry and can provide power support in sparsely populated test sites, avoiding unnecessary transportation and storage and reducing the risks existing in this process.

[0044] Combined with Figures 1-6 As shown, a disassembly tool for a misfired explosive device provided by the present invention includes: an explosion-proof plug 1, a disassembly handle 2 is installed inside the explosion-proof plug 1, a disassembly part 12 is detachably installed at the central position of one end of the disassembly handle 2, and a protrusion 106 is fixedly connected to the side wall of the disassembly part 12;

[0045] A slide rail 10, the slide rail 10 is detachably installed on the side wall of the explosion-proof plug 1, a front positioning plate 11 is slidably connected to the slide rail 10, a planetary reducer 7 is installed on the front positioning plate 11, a motor 8 is installed on one side of the planetary reducer 7, and a three-jaw chuck 6 is installed on the other side of the planetary reducer 7. The disassembly handle 2 passes through the central position of the explosion-proof plug 1 and is coaxially connected to the three-jaw chuck 6;

[0046] A rear positioning plate 9, the rear positioning plate 9 is installed on the side wall of the motor 8 and is also slidably connected to the slide rail 10.

[0047] The explosion-proof plug 1 is mainly used to prevent accidental ignition of the pyrotechnic device during the disassembly process, causing casualties. In some embodiments, the cross-sectional shape of the explosion-proof plug 1 can be set to circular, square or polygonal. For the technical solution of this application, the cross-sectional shape of the explosion-proof plug 1 is set to circular, and a long strip-shaped window 104 with safety protection is opened on the side wall of the explosion-proof plug 1 to observe whether the tooling assembly is in place and the disassembly situation of the pyrotechnic device. And this window 104 is sealed with plexiglass to facilitate observation on the premise of ensuring safety.

[0048] Furthermore, an opening is provided on one side of the explosion-proof plug 1, and a positioning component is installed at one end of the explosion-proof plug 1 close to the opening. In some embodiments, the positioning component includes an installation hole 103 opened on the side wall of the explosion-proof plug 1 and a positioning bolt 14 threadedly connected in the installation hole 103, or includes a three-jaw chuck or a four-jaw chuck fixed at one end of the explosion-proof plug 1. For the technical solution of this application, the positioning component specifically includes an installation hole 103 opened on the side wall of the explosion-proof plug 1 and a positioning bolt 14 threadedly connected in the installation hole 103. In actual use, by rotating the positioning bolt 14 to make it rotate in the installation hole 103, it can be moved to an appropriate position to clamp and fix the pyrotechnic equipment, and make the disassembled pyrotechnic equipment arranged in the center. It should be noted that for the technical solution of this application, the number of the positioning bolts 14 and the installation holes 103 are both set to four.

[0049] For the technical solution of this application, a step groove is clamped on the outer side wall of the disassembly handle 2, and a first bearing 3 is installed at the step groove. The disassembly handle 2 is rotatably connected to the explosion-proof plug 1 through the first bearing 3, so as to facilitate reducing the friction between the disassembly handle 2 and the explosion-proof plug 1 during the disassembly process.

[0050] Furthermore, a turning handle is fixedly connected to the side of the disassembly handle 2 away from the opening of the explosion-proof plug 1. The turning handle and the explosion-proof plug 1 are coaxially arranged, and a step hole 101 adapted to the turning handle is opened at the central position of the explosion-proof plug 1. A second bearing 5 is installed between the step hole 101 and the turning handle to reduce the friction between the turning handle and the step hole 101. One end of the turning handle is treated with a texture. The turning handle provided can connect the disassembly handle 2 to the three-jaw chuck 6, and is connected to the output shaft of the planetary reducer 7 through the three-jaw chuck 6. When the planetary reducer 7 rotates, it will drive the turning handle to rotate, thereby driving the disassembly handle 2 to rotate coaxially.

[0051] It should be noted that the reason why the planetary reducer 7 and the disassembly handle 2 are connected through the three-jaw chuck 6 instead of using the keyway and blind hole combination is because when the disassembly tooling is assembled, it is necessary to first connect the disassembly handle 2 and the disassembled pyrotechnic product through the disassembly part 12, and then connect the output shaft of the planetary reducer 7 to the disassembly handle 2. At this time, neither the planetary reducer 7 nor the disassembly handle 2 can rotate freely, so the three-jaw chuck 6 is used for connection.

[0052] Furthermore, an elastic member 4 is sleeved between the turning handle and the explosion-proof plug 1. The elastic member 4 can ensure that the disassembly handle 2 always presses against the pyrotechnic to be disassembled during operation, thereby preventing the disassembly member 12 from being separated from the pyrotechnic to be disassembled during the disassembly process.

[0053] Furthermore, a step blind hole compatible with the disassembly part 12 is opened on the side wall of one end of the disassembly handle 2, and the disassembly part 12 is detachably installed in the step blind hole through the pressure cap 13, so that different disassembly parts 12 can be selected according to actual needs to be installed in the step blind hole, which is convenient for adapting to different pyrotechnics and their installation environments, which not only improves the practicality, but also ensures the stability and reliability of the disassembly operation.

[0054] A threaded hole 102 is provided on the side wall of the explosion-proof plug 1, and the slide rail 10 is threadedly connected to the explosion-proof plug 1 through the threaded hole 102. In some embodiments, the slide rail 10 and the front positioning plate 11 and the rear positioning plate 9 can be slidably connected through pulleys. Specifically, pulleys are installed at the bottom of the front positioning plate 11 and the rear positioning plate 9, and a slide groove adapted to the pulley is provided above the slide rail 10. The pulley rolls in the slide groove to realize the sliding of the front positioning plate 11 and the rear positioning plate 9 on the slide rail 10;

[0055] Alternatively, the slide rail 10 and the front positioning plate 11 and the rear positioning plate 9 may be slidably connected through guide holes. Specifically, the side walls of the front positioning plate 11 and the rear positioning plate 9 are respectively provided with a first guide hole 105 and a second guide hole 108 adapted to the slide rail 10, and the front positioning plate 11 and the rear positioning plate 9 are sleeved on the slide rail 10 through the first guide hole 105 and the second guide hole 108, so that the front positioning plate 11 and the rear positioning plate 9 can slide on the slide rail 10;

[0056] When the pyrotechnic product is screwed out, it will push the disassembly handle 2, and then push the motor 8 to slide on the slide rail 10. The front positioning plate 11 and the rear positioning plate 9 can not only fix the motor 8 and the planetary reducer 7, but also ensure that the motor 8 can still drive the disassembly handle 2 to rotate when sliding.

[0057] The motor 8 is set as a stepper motor 8 or a servo motor 8. A driver 17 is electrically connected to the motor 8 through a wire. The driver 17 is electrically connected to a remote controller 16 through a wire. And a storage battery 15 is also installed on the remote controller 16. Regarding the technical solution of this application, the remote controller 16 is set as a permanent magnet brushless frequency conversion controller, with the model number QW-HV-01BL, and the driver 17 is set as a Tuoyanda intelligent remote control switch, with the model number TAD-T90P-220V. The storage battery 15 can ensure that the demolition of detonators can also be carried out in areas without power supply, reducing the dependence of the demolition tooling on the environment. A remote control module is provided between the storage battery 15 and the driver 17. The circuit on-off is controlled through the remote control module to drive the motor 8 remotely, achieving the purpose of remote control demolition. And a safety switch is provided on the remote control module. After the operator installs the equipment, the safety switch needs to be turned off before leaving, and then the remote control operation can be carried out to avoid accidentally touching the remote control switch, resulting in the motor 8 starting to work when the personnel have not evacuated.

[0058] It should be noted that the combination of the motor 8 and the planetary reducer 7 constitutes an efficient and precise power transmission system. After the motor 8 starts, the planetary reducer 7 reduces the speed and correspondingly amplifies the output torque. This deceleration effect enables the motor 8 to drive the disassembly handle 2 with a greater torque, providing sufficient power guarantee for the disassembly of misfired detonators 18.

[0059] Specifically, during actual use, first, the part to be disassembled 12 is assembled with the disassembly handle 2 by tightening the compression nut 13. Then, the disassembly handle 2 is assembled with the explosion-proof plug 1, so that the turning handle on the disassembly handle 2 passes through the second bearing 5 installed in the stepped hole 101. Then, the detonator to be disassembled is inserted into the explosion-proof plug 1 through the opening. The positioning bolt 14 is rotated to clamp and fix the detonator and position it at the middle position. Then, the protrusion 106 on the disassembled part 12 is clamped into the assembly hole of the detonator to be disassembled, and it is ensured that the spring is in a compressed state at this time. The slide rail 10 passes through the first guiding hole 105 of the front motor 8 positioning plate and the second guiding hole 108 of the rear motor 8 positioning plate in sequence, realizing the support and guiding of the motor 8 and the planetary reducer 7. Then, the three-jaw chuck 6 is used to clamp the turning handle at a suitable position to ensure the coaxial connection between the planetary reducer 7 and the disassembly handle 2. Then, the driver 17 is connected to the storage battery 15, and the safety switch is turned on, and then the remote control disassembly of misfired detonators can be started. After the disassembly is completed, it can be observed through the observation window whether the detonator is safely removed, so as to facilitate the realization of the whole process of remotely controlling the safe disassembly of misfired detonators 18. Then, the misfire reason of the detonator can be analyzed according to the disassembled misfired detonator 18.

[0060] The following Figure 7 Combined with the attached drawings

[0061] As Figure 7 shown, it is a schematic diagram of disassembling the misfired initiator 18 in a pyrotechnic device 20 of an oil and gas well using the disassembly tooling described in the present application. When the initiator in the pyrotechnic device 20 misfires, the firing pin 19 is still inserted inside the misfired initiator 18. During disassembly, it will inevitably cause friction between the firing pin 19 and the sensitive agent inside the misfired initiator 18, posing a risk of accidental ignition;

[0062] The following is an explanation of the disassembly process after the pyrotechnic device 20 misfires:

[0063] First, install the disassembly part 12 corresponding to the misfired initiator 18 on the disassembly handle 2. Pass the rotating handle of the disassembly handle 2 through the second bearing 5 installed in the stepped hole 101. Then, clamp and fix the pyrotechnic device 20 using the positioning bolt 14 and position it to the middle position of the explosion-proof plug 1. Then, insert the two protrusions 106 of the disassembly part 12 into the assembly hole of the misfired initiator 18 to be disassembled. At this time, it is necessary to ensure that the spring is in a compressed state. Then, connect the motor 8 to the planetary reducer 7, connect the front positioning plate 11 to the planetary reducer 7 through bolts, connect the rear positioning plate 9 to the motor 8, connect the slide rail 10 to the explosion-proof plug 1, and then pass the slide rail 10 through the first guiding hole 105 of the front motor 8 positioning plate and the second guiding hole 108 of the rear motor 8 positioning plate in sequence. Then, clamp the rotating handle at an appropriate position using the three-jaw chuck 6 to ensure that the planetary reducer 7 is coaxially connected to the disassembly handle 2. Then, connect the stepping motor 8, the driver 17, the remote controller 16 and the battery 15 in sequence. Turn on the safety switch on the remote controller 16, evacuate the personnel from the scene, and remotely control to start the motor 8 to perform disassembly. After disassembly, it is possible to observe through the long strip-shaped window 104 on the explosion-proof plug 1 whether the misfired initiator 18 has been safely removed.

[0064] Working principle and usage process of the present utility model: First, assemble the part to be disassembled 12 with the disassembly handle 2 by tightening the compression cap 13. Then, assemble the disassembly handle 2 with the explosion-proof plug 1, so that the turning handle on the disassembly handle 2 passes through the second bearing 5 installed in the stepped hole 101. Then, insert the explosive device to be disassembled into the explosion-proof plug 1 through the opening, rotate the positioning bolt 14 to clamp and fix the explosive device and position it at the middle position. Then, snap the protrusion 106 on the disassembling part 12 into the assembly hole of the explosive device to be disassembled, and ensure that the spring is in a compressed state at this time. Pass the slide rail 10 through the first guiding hole 105 of the positioning plate of the front motor 8 and the second guiding hole 108 of the positioning plate of the rear motor 8 in sequence to realize the support and guidance of the motor 8 and the planetary reducer 7. Then, use a three-jaw chuck 6 to clamp the turning handle at an appropriate position to ensure the coaxial connection between the planetary reducer 7 and the disassembly handle 2. Then, connect the driver 17 to the storage battery 15, turn on the safety switch, and then it is possible to remotely control the disassembly of the unexploded explosive device. After the disassembly is completed, it is possible to observe through the observation window whether the explosive device has been safely removed.
