Description

Technical Field

[0001] This application relates to the technical field of aircraft launch devices. Specifically, this application relates to a box-type launch device and its target launch method. Background Art

[0002] A box-type launch device is a launch device that can adjust the azimuth angle and elevation angle of the target.

[0003] The launch box is the core component of the box-type launch device. Before launch, it is usually necessary to transport the box-type launch device and the target to the launch site separately. Then, the target is loaded into the launch box from the port at one end of the launch box, and then launched.

[0004] The existing pre-launch preparation method requires additional equipment to store and transport the target. Before launch, it is also necessary to disassemble the target from the additional equipment at the launch site and load the target into the launch box with special loading equipment, resulting in cumbersome pre-launch preparation work. It is necessary to configure additional equipment and special loading equipment, resulting in higher upfront research and development costs. Moreover, the tool equipment at the launch site is relatively lacking, and the function of the special loading equipment is relatively single. Once an accident occurs and the disassembly or loading cannot be completed, it is easy to cause the target and the box-type launch device to be returned to the factory for repair, resulting in launch delays. Summary of the Invention

[0066] The embodiments of the present application will be described below with reference to the accompanying drawings in the present application. It should be understood that the embodiments described below in conjunction with the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions of the embodiments of the present application.

[0067] Those skilled in the art of the present technology can understand that unless specifically stated, the "the" and "this" used herein may also include the plural form. It should be further understood that the term "including" used in the specification of the present application means the presence of the described, integers, steps, operations, elements, and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components, and / or their combinations supported by the art of the present technology. The term "and / or" used herein means at least one of the items defined by the term. For example, "A and / or B" can be implemented as "A", or implemented as "B", or implemented as "A and B".

[0068] To make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0069] In the related art, the launch box is an integrally welded structure. When loading, a special loading device is required to send the target into the launch box from the port at one end of the launch box, resulting in a relatively high loading cost. Moreover, since the launch box is an integrally welded structure, it is difficult to set a limiting member for axially limiting the target inside the launch box. Even if a limiting member for axially limiting the target is provided in advance inside the launch box, it is also difficult to fix the limiting member to the target. This makes it impossible for the launch box and the target to remain relatively stationary during transportation, making it difficult for the launch box and the target to meet the conditions for being transported together. Therefore, in the related art, usually two sets of transportation devices are required to transport the target and the launch system to the launch site separately, then use a special loading device to load the target into the launch box, and finally adjust the launch azimuth and elevation angles for launching, resulting in relatively high loading costs, transportation costs, and launch costs.

[0070] To solve the above technical problems, referring to Figures 1 - 9 , an embodiment of the present application provides a box-type launch device, including a launch base 100, a launch box 200, a first locking assembly 300, and a second locking assembly 400.

[0071] The launch box 200 includes an upper box body 210 and a lower box body 220 that are detachably connected;

[0072] The first locking assembly 300 has a first end disposed on the upper box body 210;

[0073] The second locking assembly 400 is located inside the lower box body 220 and is fixedly connected to the lower box body 220.

[0074] Before the target is launched, the second end of the first locking component 300 abuts against the outer wall of the target, for radially and circumferentially limiting the target. The second locking component 400 is configured to be partially installed on the target, for axially limiting the target.

[0075] In this application, the original launch box 200 welded as a whole is divided into a detachable upper box body 210 and a lower box body 220. During loading, directly use a hoisting device to hoist the target from the through groove of the lower box body 220 into the lower box body 220, and then hoist the upper box body 210 and position and lock it with the lower box body 220 to complete the loading, without using a special loading device to load from the port of the launch box 200, saving the launch cost. The first locking component 300 and the second locking component 400 are arranged in the launch box 200. The pressure of the first locking component 300 is used to limit the radial displacement and circumferential rotation of the target, and the second locking component 400 is fixed to the target to axially limit the target. The combined action of the first locking component 300 and the second locking component 400 firmly limits the target in the launch box 200, so that the target has the conditions for transporting and storing together with the launch box 200; when the launch box 200 carrying the target is transported to the launch site and the launch azimuth and launch angle are adjusted, directly ignite and launch the target, realizing the integration of storage, transportation and launch of the target, saving the loading, transportation and launch costs.

[0076] Optionally, referring to Figures 2 - 3 , the first locking component 300 includes a mounting plate 310, a transmission member 320 and a pressing plate 330. The mounting plate 310 is fixed on the top plate of the upper box body 210. The transmission member 320 passes through and is rotatably connected to the mounting plate 310, and the transmission member 320 passes through the top plate of the upper box body 210 and extends into the launch box 200. The pressing plate 330 is arranged at the end of the transmission member 320 away from the mounting plate 310. The pressing plate 330 is used to move along a direction perpendicular to the top plate of the upper box body 210 with the transmission member 320.

[0077] A part of the transmission member 320 is located outside the upper box body 210, and a part is located inside the upper box body 210. The pressing plate 330 is arranged inside the upper box body 210 and can move along a direction perpendicular to the top plate of the upper box body 210 with the transmission member 320. When the upper box body 210 is covered above the lower box body 220 and locked with the lower box body 220, by driving the part of the transmission member 320 located outside the upper box body 210, the pressing plate 330 is driven to move downward until the pressing plate 330 abuts against the outer wall of the target, so as to use the radial pressure of the pressing plate 330 to limit the radial displacement and circumferential rotation of the target.

[0078] Optionally, referring to Figure 3 , the transmission member 320 includes a screw rod passing through the mounting plate 310, and the screw rod is threadedly connected to the mounting plate 310.

[0079] When rotating the part of the screw rod located outside the upper box body 210, the screw rod rotates and moves downward at the same time, so as to drive the pressing plate 330 to rotate and move downward at the same time until it abuts against the outer side wall of the target. For the convenience of holding, a rotating wheel 340 is installed at one end of the screw rod located outside the upper box body 210. The outer shape of the rotating wheel 340 can be designed into shapes such as square, circular or irregular, which is not limited here. In this application, the rotating wheel 340 is taken as an example of a disc shape for illustration.

[0080] Optionally, the pressing plate 330 is designed as an arc-shaped plate according to the radian of the outer side wall of the target.

[0081] Optionally, a rubber plate 350 can also be arranged on the contact surface of the pressing plate 330 for contacting the target to buffer the hard contact between the pressing plate 330 and the target and avoid generating hard indentations or abrasions on the outer side wall of the target. The rubber plate 350 and the pressing plate 330 can be fixedly connected or detachably connected, which is not limited here.

[0082] Optionally, referring to Figures 4 - 5 , the second locking component 400 includes a holding ring 410 and an adapter 420 connected to the holding ring 410. The holding ring 410 is fixed on the end face of the tail of the target, and the holding ring 410 is fixed at the end of the lower box body 220 through the adapter 420.

[0083] Before loading, first fit the holding ring 410 to the outer side wall of the target to hold the outer side wall of the target, and then use a fixing member, such as a bolt, etc. to fix the holding ring 410 on the target. Then use the adapter 420 to fix the holding ring 410 into the lower box body 220. In order to ensure the stability of the axial limit of the target, the holding ring 410 can be set as an integral ring around the circumference of the target. This integral ring has an opening with adjustable size to facilitate sleeving the holding ring 410 outside the target. The holding ring 410 can also be set as X (X≥2), and X holding rings 410 are arranged at intervals around the circumference of the target. At least two holding rings 410 can be located on the same cross-section of the target, or can be arranged axially staggered along the target. For the consideration of the bonding strength between the target and the lower box body 220, the case where at least two holding rings 410 are located on the same cross-section of the target is taken as an example for illustration.

[0084] Optionally, the adapter 420 includes an adapter shaft 421 that can rotate radially around the holding ring 410, a first adapter seat 422 fixedly connected to the adapter shaft 421, and a second adapter seat 423 fixed to the first adapter seat 422. The second adapter seat 423 is used to be fixed in the lower box body 220.

[0085] In practical applications, the adapter shaft 421 and the first adapter seat 422 of the adapter 420 are integrally formed on the holding ring 410 before the holding ring 410 is fixed. When fixing, it is only necessary to first fix a plane of the second adapter seat 423 to the lower box 220, and then fix the first adapter seat 422 and the second adapter seat 423 to achieve the fixation of the target, the holding ring 410 and the lower box 220. When the first adapter seat 422 and the second adapter seat 423 are fixed, the adapter shaft 421 can be rotated to adjust the appropriate fixing angle of the first adapter seat 422, so as to facilitate the installation of the holding ring 410 at various angles.

[0086] Optionally, the adapter 420 can be set on the side of the holding ring 410 away from the arc groove, or on the front or rear side of the holding ring 410. In the present application, the adapter 420 is set on the side of the holding ring 410 away from the arc groove.

[0087] Optionally, refer to Figure 5 , the adapter 420 is fixed on the upper end surfaces of the two opposite sides of the lower box body 220, so as to ensure the uniform weight in the launch box 200, and facilitate the fixation of the second adapter seat 423 to the lower box body 220 and the fixation of the first adapter seat 422 to the second adapter seat 423. At the same time, in order to facilitate the fixation of the second adapter seat 423 to the lower box body 220, the bottom surface of the second adapter seat 423 is a plane. In the present application, the second adapter seat 423 is an L-shaped plate, and ribs are installed on both sides to ensure the strength of the second adapter seat 423.

[0088] Optionally, refer to Figure 5 A rudder surface fixing seat 430 for limiting the rudder surface on the target is provided on the holding ring 410. The rudder surface fixing seat 430 extends along the axial direction of the target, and the rudder surface fixing seat 430 is provided with a clamping groove 431 extending along the radial direction of the holding ring 410 for clamping both sides of the rudder surface.

[0089] When the holding ring 410 is installed, the rudder surfaces of the target are aligned one by one with the clamping grooves 431 of the rudder surface fixing seat 430, so that the rudder surfaces are restricted in the clamping grooves 431 of the rudder surface fixing seat 430. By fixing the holding ring 410 on the tail end face of the target, the rudder surface of the target is clamped while the target is axially limited, so as to further reduce the probability of axial rotation of the target and improve the limiting effect of the target.

[0090] Optionally, the position of the rudder surface fixing seat 430 on the holding ring 410 is specifically set according to the actual position of the target rudder surface. In the present application, the rudder surface fixing seat 430 is respectively provided with one at each end of each holding ring 410.

[0091] Optionally, refer to Figure 6, guide rails 500 are provided on the end faces of opposite sides of the lower box body 220, and the guide rails 500 extend along the length direction of the lower box body 220. The guide rails 500 are used to cooperate with the sliders on the target. A bullet blocking block 600 is provided at the tail end of the lower box body 220, and the bullet blocking block 600 is used to axially limit the target in the erected state.

[0092] During loading, the slider of the target is combined with one end of the guide rail 500, and then the target is pushed so that the slider slides along the guide rail 500 to initially place the target on the lower box body 220. After that, the holding ring 410 and the lower box body 220 are fixed by using the adapter 420 to realize the fixation of the target and the lower box body 220.

[0093] After the target is loaded, the upper box body 210 is hoisted so that the upper box body 210 is locked with the lower box body 220. Matching positioning parts 240 are provided on both the upper box body 210 and the lower box body 220 to facilitate the guiding and positioning of the upper box body 210 and the lower box body 220. The positioning parts 240 of the upper box body 210 are located on both sides of the upper box body 210, and positioning holes are provided in the positioning parts 240. The positioning parts 240 of the lower box body 220 include guide posts for cooperating with the positioning holes. When the upper box body 210 is hoisted, the positioning posts are inserted into the positioning holes one by one, and then fixed by using fixing parts to realize the positioning and locking between the upper box body 210 and the lower box body 220, ensuring that the two end faces of the upper box body 210 and the lower box body 220 are both in the same plane.

[0094] Optionally, referring to Figure 1 , the launch box 200 further includes box covers 230 at both ends. The box covers 230 are detachably connected to both the upper box body 210 and the lower box body 220. After the target is fixed in the lower box body 220 and the upper box body 210 is locked with the lower box body 220, the front and rear box covers 230 are installed so that the launch box 200 meets the conditions for long-distance transportation. Before launch, the box cover 230 at the front end of the target is removed so that the target meets the launch conditions.

[0095] When the target and the launch box 200 are transported to the launch site together, the first locking component 300, the second locking component 400, and the box cover 230 at the front end of the target need to be removed before launch. By providing a bullet blocking block 600 at the tail end of the lower box body 220, when the launch box 200 is erected to the set launch angle and the target is in the launch state, the slider on the target abuts against the bullet blocking block 600, so as to be able to axially limit the target and prevent the tail end of the target from contacting the box cover 230, causing damage to the target.

[0096] Optionally, referring to Figure 4 , a plug-in and unplugging baffle 700 is further fixed on the bottom surface at the tail end of the lower box body 220. The plug-in and unplugging baffle 700 extends in a direction perpendicular to the bottom surface of the lower box body 220 for fixing the plug-in and unplugging cable of the target before launch and unplugging the plug-in and unplugging cable after the engine is ignited.

[0097] Optionally, referring to Figure 1 and Figures 7 - 9 , the box-type launching device of the present application further includes an azimuth angle adjustment assembly 800 and an elevation angle adjustment assembly 900.

[0098] The azimuth angle adjustment assembly 800 includes a slewing bearing 810 rotatably arranged on the launching base 100, a turntable 820 arranged on the slewing bearing 810, and a crank-slider mechanism 830 for driving the turntable 820 to rotate. The tail end of the lower box body 220 is hinged to the turntable 820, and the azimuth angle adjustment assembly 800 is used to drive the launching box 200 to rotate around the vertical direction.

[0099] The elevation angle adjustment assembly 900 is arranged on the turntable 820 and includes an erection frame 910 hinged at one end to the turntable 820 and an erection member 920. The launching box 200 is locked on the erection frame 910, and the end of the erection frame 910 away from the turntable 820 is hinged to the erection member 920. The erection member 920 is telescopic, and the end of the erection member 920 away from the turntable 820 is hinged to the erection frame 910, and is used to drive the launching box 200 to rotate around the hinge point between its first end and the turntable 820.

[0100] After the target is loaded into the launching box 200 and the launching box 200 is sealed, the erection frame 910 is laid flat, then the launching box 200 with the target is hoisted onto the erection frame 910 and locked, and finally they are transported to the launching site together. Before launching, the launching azimuth of the target is adjusted by using the azimuth angle adjustment assembly 800, and the launching elevation angle of the target is adjusted by using the elevation angle adjustment assembly 900.

[0101] During adjustment, the crank-slider mechanism 830 is used to drive the turntable 820 to rotate, and the slewing bearing 810 is arranged to ensure the smooth rotation of the turntable 820. The rotation of the turntable 820 drives the elevation angle adjustment assembly 900 and the launching box 200 to rotate around the vertical direction, thereby adjusting the launching direction of the launching box 200. After the launching direction is adjusted, the turntable 820 and the launching base 100 are locked to ensure that the turntable 820 no longer rotates, and then the launching elevation angle of the launching box 200 is adjusted. During adjustment, the erection member 920 is controlled to extend. As the erection member 920 extends, the included angle between the launching box 200 and the turntable 820 continuously increases. When the launching box 200 rotates to the appropriate launching elevation angle, the erection member 920 is stopped. Then the target can be launched.

[0102] The erection member 920 can be any structure with sufficient supporting force and telescopic performance. In the present application, only the case where the erection member 920 uses a hydraulic erection cylinder is taken as an example for illustration. The structure of the hydraulic erection cylinder is simple, the output force is large, and the performance is stable and reliable, ensuring the smooth rotation of the launching box 200 around the hinge point between it and the turntable 820.

[0126] The beneficial technical effects brought by the technical solution provided by the embodiment of the present application include: The launch box 200 is designed as a split type. During loading, only basic lifting equipment is required to lift the target into the lower box body 220. After fixing the second locking assembly 400 in the lower box body 220, then use the lifting equipment to lift the upper box body 210 to form the launch box 200 with the lower box body 220. There is no need to use special loading equipment to load the target from the port of the launch box 200, saving the research and development cost in terms of loading equipment.

[0127] In addition, designing the launch box 200 as a split type not only reduces the difficulty of target loading but also reduces the difficulty of production, processing, and subsequent maintenance of the launch box. At the same time, it also provides sufficient operating space for the fixation of the second locking assembly 400 in the lower box body 220, facilitating the axial limit of the target. The first locking assembly 300 and the second locking assembly 400 are used to respectively perform reliable radial and axial limits on the target, enabling the target to be transported and stored together with the launch box 200. When the target and the launch device are transported to the launch site together, the target can be directly launched, saving transportation costs and launch costs, realizing the integration of storage, transportation, and launch of the target and the box-type launch device of the present application, and shortening the preparation time before launch.
