Description

Technical Field

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

[0002] The launch tube is the storage, transportation, and launch device for individual cruise missiles. During individual combat, the internal ignition and launch control module ignites the main charge in the gas generator. The high-pressure gas performs work in the enclosed space between the piston and the gas generator, converting internal energy into mechanical energy to drive the piston to accelerate, thereby allowing the cruise missile in contact with the piston inside the launch tube to gain sufficient kinetic energy to break free from the tube mouth and fly out. To ensure reliable launch, the ignition and launch control module should be tested for electrical performance after the launch tube is produced, without the front cover installed. However, during the testing process, static electricity or improper operation may cause misfires, 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 test the electrical performance of the launch tube.

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

[0005] In response to the shortcomings of existing technical solutions, the utility model provides a protective isolation device for electrical performance testing of cruise missile launchers, which overcomes the shortcomings of existing technologies and can provide all-round protection for testing personnel, testing equipment, and surrounding equipment and facilities, effectively improving operational safety.

[0006] In order to solve the above technical problems, one of the purposes of this utility model is to provide a protective isolation device for electrical performance testing of a cruise missile launcher. The device consists of a box body 1, a box cover 2, a front saddle 5, a rear saddle 8, a single-ear lock piece 9 and a lock pin 10. The box cover 2 is hinged to the box body 1.

[0007] The box body 1 is welded by a left side panel 1.2, a front side panel 1.3, a right side panel 1.6, a rear side panel 1.9 and a bottom panel 1.8;

[0008] The box cover 2 is composed of a cover plate 2.1, a double-ear lock piece 2.2, a guide sleeve 2.8 and a guide pin 2.9. Two double-ear lock pieces 2.2 are welded on the long side of the cover plate 2.1, and the guide sleeve 2.8 is welded on the short side of the cover plate 2.1. The guide pin 2.9 is inserted into the guide sleeve 2.8, and the end of the guide pin 2.9 is provided with an annular groove.

[0009] The partition plate 1.4, the front support plate 1.5 and the rear support plate 1.7 are welded in sequence in the box body, and the front saddle 5 and the rear saddle 8 are fixed to the front support plate 1.5 and the rear support plate 1.7 respectively by bolt assemblies;

[0010] Two single-ear locking pieces 9 are welded on the left side plate 1.2. The two double-ear locking pieces 2.2 on the box cover 2 are aligned with the two single-ear locking pieces 9 on the box body and then two locking pins 10 are inserted to lock the box body and the box cover.

[0011] Furthermore, the device is also provided with a movable baffle 4 for limiting the axial displacement of the launch tube. The movable baffle is fixed on the partition 1.4 and bears 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, which are designed to accommodate the protruding electrical socket and detection cable at the bottom of the launch tube.

[0013] Furthermore, four pads 1.1 are welded at the four corners of the bottom of the device box.

[0014] Furthermore, the sides of the partition plate 1.4, the front support plate 1.5 and the rear support plate 1.7 are welded to the interior of the box.

[0015] Furthermore, the box cover plate 2.1 is provided with a plurality of pressure relief holes, so that the support reaction force only acts vertically downward.

[0016] Furthermore, the device also includes a support rod 3, one end of which is connected to the guide sleeve 2.8 on the box cover through a guide pin 2.9, and the other end is fixed to the support ear 1.10 on the front side plate 1.3 for flipping up the box cover and fixing it.

[0017] Furthermore, the box body 1 and the box body 2 are connected by a hinge 12, and hinge pieces of the hinge 12 are welded to the cover plate 2.1 and the right side plate 1.6 of the box body 2 respectively.

[0018] Furthermore, I-shaped angle steel bars 2.4, angle steel bars 2.5, angle steel bars 2.6 and angle steel bars 2.7 are welded to the back of the box cover.

[0019] Furthermore, the box cover 2 is provided with a wire outlet hole, and it is ensured that the detection cable is connected to the detection equipment after being led out from the wire outlet hole 1 and the wire outlet hole 2 of the box cover.

[0020] The above one or more technical solutions of the present invention have at least one or more of the following technical effects:

[0021] (1) The box is designed as a closed structure with no lateral pressure relief gaps. The explosion shock wave and fragments cannot fly out laterally, effectively ensuring the safety of the inspection personnel, inspection equipment and facilities.

[0022] (2) The box cover is provided with multiple pressure relief holes, which can not only realize explosion pressure relief, but also filter large particle fragments. At the same time, the pressure relief support has a downward reaction force, ensuring that the protective isolation device will not move horizontally.

[0023] (3) The saddle connection holes are designed to have the same size, and different saddles are interchangeable. By replacing different saddles, the support requirements of various types of launch tubes can be met.

[0024] (4) The launch tube is placed horizontally on the saddle, and the movable baffle limits the recoil force of accidental firing. The rapid movement of the piston in the barrel mouth compresses the gas pressure to act on the box wall. The two forces constitute an internal force, which is transmitted without external force, further improving operational safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] A protective isolation device for testing the electrical performance of cruise missile launchers provides comprehensive isolation and protection during testing. The device consists of a housing, a movable baffle, a saddle, hinges, a lid (equipped with multiple pressure relief holes), locking plates, locking pins, and support rods. The housing is welded with a partition and front and rear support plates, to which the front and rear saddles are bolted. The lid, shaped like a door, is connected to the housing via hinges and locked with a locking plate and locking pin.

[0041] When testing the electrical performance, flip up the box cover and fix it with a support rod, place the launch 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 launch 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 launch tube, and are respectively led out through the corresponding lead holes on the cover to connect to the testing equipment; then lower the support rod, lock the box body and box cover with the locking plate and locking pin, and you can start the electrical performance test of the launch 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 flight of high-temperature fragments caused by 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 providing all-round isolation and protection 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 conjunction with the embodiments and drawings of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments obtained. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within 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 and impact of accidental ignition of the launch tube, and forms the structural design scheme of the utility model 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. If the launch tube misfires and flies out in the recoil direction, without boundary restrictions, collisions, rebounds, or even "random movements" may occur, causing personal injury or damage to equipment and facilities. Disintegration of the launch tube structure. If the launch tube misfires, the piston and the tube body disintegrate and separate, causing the launch tube body and piston to fly out in opposite directions, which may cause personal injury or mechanical injury accidents. Combustion and explosion of the launch tube. If the launch tube misfires, combustion and explosion may occur, and fragments may 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 support 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. 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, to facilitate access to the launch tube, the cross-section of the housing 1 is designed to be trapezoidal. The size of the housing 1 is determined by the dimensions of the launch tube, and the strength of each component is calculated based on the gas pressure generated by the launch tube explosion and the maximum recoil force in the event of an accidental launch. The housing 1 is welded together from the front side panel 1.3, rear side panel 1.9, left side panel 1.2, right side panel 1.6, and bottom panel 1.8.

The center of the partition 1.4 is open to accommodate the protruding electrical socket and detection cable on the bottom of the launch tube.

[0049] The box cover structure is as follows Figure 3 、 Figure 4 As shown, the structural strength of the cover is calculated based on the gas pressure generated by the launch tube explosion. The cover 2 is welded together from a cover plate 2.1, angle steels 2.4, 2.5, 2.6, and 2.7. Two double-ear lock plates 2.2 are welded to the long sides of the cover plate 2.1, and a handle 2.3 is welded in the middle. A guide sleeve 2.8 is welded to the short side of the cover plate 2.1, and a guide pin 2.9 is inserted into the sleeve 2.8. The end of the guide pin 2.9 is provided with a circumferential groove.

[0050] The overall structure of the protective isolation device is as follows Figure 5-11 As shown. The housing 1 and 2 are connected by four hinges 12, the hinges of which are welded to the cover plate 2.1 and the right side panel 1.6 of the housing 2. One end of the support rod 3 fits into the support ear 1.10 and is locked by a retaining ring 11. The housing 2 is tilted to a certain angle, and the guide pin 2.9 is pushed into the hole at the other end of the support rod 3 to lift and secure the housing 2. The front saddle 5 and rear saddle 8 are fixed to the front support plate 1.5 and rear support plate 1.7, respectively, with bolts 6 and nuts 7. The movable baffle 4 fits into the slots of the bulkhead 1.4. Two single-ear locking tabs 9 are welded to the left side panel 1.2. When locking the housing 2, the two double-ear locking tabs 2.2 on the housing 2 align with the two single-ear locking tabs 9 on the housing, and then two locking pins 10 are inserted. The movable baffle 4 is added to compensate for the reduced strength of the bulkhead 1.4 after accommodating the opening for the electrical socket protruding from the bottom of the launch tube. For ease of use, the two locking pins 10 are pulled out and then connected to the two hanging ears 1, 11 via soft ropes.

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

[0052] Open the lid. Grip the handle 2.3 to flip up the lid, and rotate the support rod 3 so that its end hole fits into the guide pin 2.9 to complete the lid opening.

[0053] Place the launch tube. Place the launch tube horizontally on the front saddle 5 and rear saddle 8. Insert the raised electrical socket on the bottom of the launch tube into the opening of the movable baffle 4 and the partition 1.4. Insert the detection cable into the electrical socket on the bottom of the launch tube and the electrical socket inside the tube mouth.
