Description

Technical Field

[0001] The invention relates to the technical field of launch tubes, and in particular to a protective isolation device for electrical performance detection of a cruise missile launch tube. Background Art

[0002] The launch tube is a storage, transportation and launching device for individual cruise missiles. When a single soldier is in combat, the internal ignition and launch control module ignites the main charge in the gas generator, and the high-pressure gas does work in the confined space between the piston and the gas generator. The internal energy is converted into mechanical energy to drive the piston to accelerate, so that the cruise missile in contact with the piston in the launch tube body gains enough kinetic energy to break away from the tube mouth and fly out. To ensure reliable launch, the electrical performance of the ignition and launch control module should be tested without assembling the front cover after the launch tube is produced. However, static electricity or improper operation may cause misfires during the detection process, causing the launch tube to fly out axially, burn and explode, or disintegrate, resulting in personal injury or damage to equipment and facilities.

[0003] The existing technical solution is to design a testing work platform, and install a protective isolation baffle of a certain height in the middle of the work platform; the launch tube is placed horizontally on one side of the protective isolation baffle, and the testing equipment and operators are located on the other side of the protective isolation baffle. The detection cable connected to the electrical performance detection interface of the launch tube bypasses the protective isolation baffle and is connected to the special detection equipment, and then the special detection equipment is started to detect the electrical performance of the launch tube.

[0004] The existing technical solution adopts isolation protection baffle for protection, which can only provide simple, partial and positive protection for the inspection personnel and inspection equipment when the electrical performance detection of the launch tube accidentally fires and creates a danger. It cannot provide all-round and effective protection against dangerous sources such as the impact and rebound after the launch tube flies out axially after the launch tube accidentally fires, the high-speed and high-temperature fragments flying out after the launch tube burns and explodes or the structure disintegrates, and the overpressure shock wave generated at the moment of combustion and explosion.

[0011] Furthermore, the device is also provided with a movable baffle 4 for limiting the axial displacement of the launch tube, the movable baffle 4 being fixed on the partition 1.4 and bearing the maximum recoil force when the launch tube misfires.

[0012] Furthermore, the movable baffle 4 and the partition 1.4 are open in the middle, and are designed and used to accommodate the protruding electrical socket and detection cable at the bottom of the launch tube.

[0040] A protective isolation device for electrical performance testing of cruise missile launch tubes is used to achieve all-round isolation protection during electrical performance testing of launch tubes. The device consists of a box body, a movable baffle, a saddle, a hinge, a box cover (with multiple pressure relief holes), a locking plate, a locking pin, a support rod, etc. The partition plate and the front and rear support plates are welded in the box body in sequence, and the front and rear saddles are fixed on them by bolt assemblies; the box cover is shaped like a door leaf and is connected to the box body through a hinge, and the box body and the box cover are locked by locking plates and locking pins.

[0041] When testing the electrical performance, flip up the box cover and fix it with a support rod, place the launching tube horizontally on the front and rear saddles, and insert the movable baffle into the baffle slot of the box body; the bottom of the launching tube contacts the movable baffle, and the raised electrical socket on the bottom of the tube is located in the gap between the movable baffle and the baffle; two sets of detection cables are respectively connected to the electrical sockets on the bottom and muzzle side of the launching tube, and are respectively led out through the corresponding lead holes on the cover to connect with the testing equipment; then lower the support rod, lock the box body and the box cover with the locking plate and locking pin, and start the electrical performance test of the launching tube.

[0042] The above-mentioned device is used to enclose the launch tube in a limited space, which not only limits the axial flight of the launch tube after an accidental firing, but also limits the flying of high-temperature fragments due to combustion, explosion or structural disintegration. At the same time, the pressure relief hole in the box cover plays a pressure relief role, and the reaction force of the pressure relief support acts downward on the work surface where the device is located, and no lateral movement occurs, thereby playing an all-round isolation and protection function for the surrounding inspection personnel, equipment and facilities.

[0043] 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.

[0044] This proposal proposes key design points of the protective isolation device based on a detailed analysis of the sources of danger of accidental ignition of the launch tube and its impact, and forms the structural design scheme of the invention accordingly.

[0045] Analysis of the sources of danger and their impact during the electrical performance test of the launch tube, and the axial flight of the launch tube. The launch tube misfires and flies out in the recoil direction. When there is no boundary restriction, collision, rebound, or even "randomness" may occur, causing personal injury or damage to equipment and facilities. Disintegration of the launch tube structure. The launch tube misfires, and the piston and the barrel disintegrate and separate, causing the launch tube body and the piston to fly out in opposite directions, which may cause casualties or mechanical injury accidents. Combustion and explosion of the launch tube. The launch tube misfires, which may cause combustion and explosion, and fragments fly out axially or radially, causing personal injury or damage to equipment and facilities.

[0046] The key points in the design of electrical performance detection protection isolation device are as follows:

[0047] A pressure relief hole should be set on the top of the device, and the reaction force of the pressure relief support must be vertically downward. Side pressure relief is not allowed to prevent the device from moving laterally. A supporting saddle should be set inside the device to ensure that the axis of the launch tube is horizontal and the recoil force acts in the horizontal direction. A movable baffle should be set inside the device to limit the axial displacement of the launch tube, and the structural strength should meet the maximum thrust load of the launch tube ignition.

[0048] The structural design of the protective isolation device, the box structure is as follows Figure 1As shown, in order to facilitate the removal of the launch tube, the cross-section of the box body 1 is designed to be trapezoidal. The size of the box body 1 is determined according to the size of the launch tube, and the strength of each part of the box body is calculated according to the gas pressure generated after the launch tube explodes and the maximum recoil force after the launch tube misfires. The box body 1 is welded together by the front side plate 1.3, the rear side plate 1.9, the left side plate 1.2, the right side plate 1.6, and the bottom plate 1.8.

The box body 1 and the box body 2 are connected by four hinges 12, and the hinge pieces of the hinge 12 are respectively welded to the cover plate 2.1 and the right side plate 1.6 of the box body 2; the hole at one end of the support rod 3 is embedded in the support ear 1.10 and locked by the retaining ring 11; the box cover 2 is flipped up to a certain angle, and the guide pin 2.9 is pushed into the hole at the other end of the support rod 3, so that the box cover 2 can be supported and fixed; the front saddle 5 and the rear saddle 8 are respectively fixed to the front support plate 1.5 and the rear support plate 1.7 by bolts 6 and nuts 7; the movable baffle 4 is embedded in the card slot of the partition 1.4; two single-ear lock pieces 9 are welded on the left side plate 1.2; when the box cover 2 is locked, the two double-ear lock pieces 2.2 on the box cover 2 are aligned with the positions of the two single-ear lock pieces 9 on the box body, and then two lock pins 10 are inserted. The movable baffle 4 is added to compensate for the reduced strength of the partition 1.4 after accommodating the opening of the protruding electrical socket at the bottom of the launch tube. For easy use, the two locking pins 10 are respectively connected to the two hanging ears 1.11 through soft ropes after being pulled out.

[0051] The detection status of the protective isolation device is as follows: Fig.12 According to the testing requirements of the electrical performance of the launch tube, the testing process is divided into five steps, namely, opening the cover, placing the launch tube, closing the cover, testing, and taking out the launch tube.

[0052] Open the lid. Hold the handle 2.3 to flip up the lid, turn the support rod 3 so that its end hole fits into the guide pin 2.9, and the lid is opened.
