DETAILED DESCRIPTION

[0021] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0022] It will be understood by those skilled in the art that, unless expressly stated, the "said" and "the" used herein may also include plural forms. It should be further understood that the term "including" used in the specification of the present application refers to the existence of the said, integer, step, operation, element and / or component, but does not exclude the implementation of other features, information, data, steps, operations, elements, components and / or their combinations supported by the technical field. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" can be implemented as "A", or as "B", or as "A and B".

[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0024] In the related art, the launch box is an integral welded structure, and during loading, a dedicated loading device is required to deliver the target into the launch box from the port at one end of the launch box, resulting in a high loading cost. Moreover, since the launch box is an integral welded structure, it is difficult to set a limiter in the launch box to axially limit the target. Even if a limiter is provided in advance in the launch box to axially limit the target, it is difficult to fix the limiter to the target. This makes it impossible for the launch box and the target to remain relatively still during transportation, making it difficult for the launch box and the target to be transported together. Therefore, in the related art, two sets of transportation equipment are usually required to transport the target and the launch system to the launch site respectively, and then use dedicated loading equipment to load the target into the launch box, and finally adjust the launch azimuth and pitch angle for launch, resulting in high loading costs, transportation costs and launch costs.

[0025] In order to solve the above technical problems, refer to Figure 1-Figure 9An embodiment of the present application provides a box-type launching device, including a launching base 100, a launching box 200, a first locking assembly 300 and a second locking assembly 400.

[0026] The launch box 200 includes an upper box body 210 and a lower box body 220 that are detachably connected; A first locking assembly 300, a first end of which is disposed on the upper box body 210; The second locking assembly 400 is located in the lower box body 220 and is fixedly connected to the lower box body 220 .

[0027] Before the target is launched, the second end of the first locking assembly 300 abuts against the outer wall of the target to limit the target radially and circumferentially. The second locking assembly 400 is configured to be partially mounted on the target to limit the target axially.

[0028] The present application divides the launch box 200, which was originally welded together, into an upper box body 210 and a lower box body 220 that are detachably connected. When loading, the target is directly hoisted from the through slot of the lower box body 220 into the lower box body 220 using a hoisting device, and then the upper box body 210 is hoisted and positioned and locked with the lower box body 220 to complete the loading. There is no need to use special loading equipment to load from the port of the launch box 200, saving the launch cost. A first locking assembly 300 and a second locking assembly 400 are set in the launch box 200, and the radial displacement and circumferential rotation of the target are limited by the pressure of the first locking assembly 300, and the second locking assembly 400 is fixed to the target to limit the axial position of the target. The combined action of the first locking assembly 300 and the second locking assembly 400 securely positions the target in the launch box 200, thereby enabling the target to be transported and stored together with the launch box 200. When the launch box 200 carrying the target is delivered to the launch site, and the launch orientation and angle are adjusted, the target can be directly ignited and launched, thus realizing the integration of target storage, transportation and launch, and saving loading, transportation and launch costs.

[0029] Optionally, refer to Figure 2-Figure 3 The first locking assembly 300 includes a mounting plate 310, a transmission member 320 and a pressure 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 pressure plate 330 is arranged at one end of the transmission member 320 away from the mounting plate 310. The pressure plate 330 is used to move along with the transmission member 320 in a direction perpendicular to the top plate of the upper box body 210.

[0030] A portion of the transmission member 320 is located outside the upper box 210, and a portion is located inside the upper box 210. The pressing plate 330 is arranged inside the upper box 210 and can move along with the transmission member 320 in a direction perpendicular to the top plate of the upper box 210. When the upper box 210 is covered above the lower box 220 and locked with the lower box 220, the pressing plate 330 is driven to move downward by driving the portion of the transmission member 320 located outside the upper box 210 until the pressing plate 330 abuts against the outer wall of the target, thereby limiting the radial displacement and circumferential rotation of the target by using the radial pressure of the pressing plate 330 on the target.

[0031] Optionally, refer to Figure 3 The transmission member 320 includes a screw rod penetrating the mounting plate 310 , and the screw rod is threadedly connected to the mounting plate 310 .

[0032] When the screw rod is rotated outside the upper box 210, the screw rod moves downward while rotating, thereby driving the pressure plate 330 to rotate and move downward until it contacts the outer wall of the target. In order to facilitate holding, a rotating wheel 340 is installed at one end of the screw rod outside the upper box 210. The shape of the rotating wheel 340 can be designed to be square, round, or special-shaped, which is not limited here. This application takes the rotating wheel 340 as a disc as an example for explanation.

[0033] Optionally, the pressing plate 330 is designed as a curved plate according to the curvature of the outer side wall of the target.

[0034] Optionally, a rubber plate 350 may be provided on the contact surface of the pressure plate 330 for contacting the target to buffer the hard contact between the pressure plate 330 and the target and avoid hard indentations or wear on the outer wall of the target. The rubber plate 350 and the pressure plate 330 may be fixedly connected or detachably connected, which is not limited here.

[0035] Optionally, refer to Figure 4-Figure 5 The second locking assembly 400 includes a ring 410 and an adapter 420 connected to the ring 410 . The ring 410 is fixed to the tail end face of the target, and the ring 410 is fixed to the tail end of the lower box 220 through the adapter 420 .

[0036] Before loading, the holding ring 410 is first fitted to the outer wall of the target to hold the outer wall of the target, and then the holding ring 410 is fixed to the target using a fixing member, such as a bolt. Then the holding ring 410 is fixed to the lower box 220 using the adapter 420. 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, and the integral ring has an opening of adjustable size, so that the holding ring 410 can be set outside the target. The holding ring 410 can also be set to X (X≥2), and the 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 they can be staggered along the axial direction of the target. Considering the bonding strength between the target and the lower box 220, at least two holding rings 410 are located on the same cross section of the target as an example for explanation.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Optionally, refer to Figure 5A 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.

[0042] 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.

[0043] 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.

[0044] Optionally, refer to Figure 6 The lower box 220 is provided with guide rails 500 on the opposite sides of the end surface, and the guide rails 500 extend along the length direction of the lower box 220. The guide rails 500 are used to cooperate with the slider on the target. The lower box 220 is provided with a bullet stopper 600 at the tail end, and the bullet stopper 600 is used to limit the axial position of the target in the erected state.

[0045] During loading, the slider of the target is coupled to 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 220 , and then the adapter 420 is used to fix the ring 410 to the lower box 220 , thereby fixing the target to the lower box 220 .

[0046] After the target is loaded, the upper box 210 is hoisted so that the upper box 210 and the lower box 220 are locked. The upper box 210 and the lower box 220 are both provided with matching positioning members 240 to facilitate the guidance and positioning of the upper box 210 and the lower box 220. The positioning members 240 of the upper box 210 are located on both sides of the upper box 210, and positioning holes are provided on the positioning members 240. The positioning members 240 of the lower box 220 include guide columns for cooperating with the positioning holes. When the upper box 210 is hoisted, the positioning columns are inserted into the positioning holes one by one, and then fixed with fixing members to achieve the positioning and locking between the upper box 210 and the lower box 220, and ensure that the two end faces of the upper box 210 and the lower box 220 are located in the same plane.

[0047] Optionally, refer to Figure 1The launch box 200 also includes box covers 230 at both ends, and the box covers 230 are detachably connected to the upper box body 210 and the lower box body 220. After the target is fixed to the lower box body 220 and the upper box body 210 and the lower box body 220 are locked, the front and rear box covers 230 are installed to make the launch box 200 ready for long-distance transportation. Before launching, the box cover 230 at the front end of the target is removed to make the target ready for launching.

[0048] After the target and the launch box 200 are transported to the launch site together, the first locking assembly 300, the second locking assembly 400 and the box cover 230 at the front end of the target need to be removed before launching. By providing a bullet stop block 600 at the tail end of the lower box body 220, when the launch box 200 is erected to the set launch angle so that the target is in a launching state, the slider on the target abuts against the bullet stop block 600, thereby limiting the target axially and preventing the tail end of the target from contacting the box cover 230 and causing damage to the target.

[0049] Optionally, refer to Figure 4 A disconnecting baffle plate 700 is also fixed on the bottom surface of the tail end of the lower box body 220. The disconnecting baffle plate 700 extends in a direction perpendicular to the bottom surface of the lower box body 220 to fix the target disconnecting cable before launching and to disconnect the disconnecting cable after the engine is ignited.

[0050] Optionally, refer to Figure 1 and Figure 7-Figure 9 The box-type launching device of the present application also includes an azimuth angle adjustment component 800 and a pitch angle adjustment component 900.

[0051] The azimuth angle adjustment assembly 800 includes a slewing bearing 810 rotatably mounted on the launch base 100, a turntable 820 mounted 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 launch box 200 to rotate in the vertical direction.

[0052] The pitch angle adjustment assembly 900 is disposed on the turntable 820, and includes a vertical frame 910 hinged at one end on the turntable 820 and a vertical member 920. The launch box 200 is locked on the vertical frame 910, and one end of the vertical frame 910 away from the turntable 820 is hinged to the vertical member 920. The vertical member 920 is retractable, and one end of the vertical member 920 away from the turntable 820 is hinged to the vertical frame 910, and is used to drive the launch box 200 to rotate around the hinge point between its first end and the turntable 820.

[0053] After the target is loaded into the launch box 200 and the launch box 200 is sealed, the erection frame 910 is laid flat, and then the launch box 200 with the target is hoisted onto the erection frame 910, locked, and finally transported to the launch site. Before launching, the azimuth adjustment component 800 is used to adjust the launch azimuth of the target, and the pitch adjustment component 900 is used to adjust the launch pitch angle of the target.

[0054] During adjustment, the crank slider mechanism 830 is used to drive the turntable 820 to rotate, and the slewing bearing 810 is provided to ensure the smooth rotation of the turntable 820. The rotation of the turntable 820 drives the pitch angle adjustment assembly 900 and the launch box 200 to rotate in the vertical direction, thereby adjusting the launch direction of the launch box 200. After the launch direction is adjusted, the turntable 820 and the launch base 100 are locked to ensure that the turntable 820 no longer rotates, and then the launch pitch angle of the launch box 200 is adjusted. During adjustment, the erecting piece 920 is controlled to extend, and as the erecting piece 920 extends, the angle between the launch box 200 and the turntable 820 continues to increase. When the launch box 200 rotates to a suitable launch pitch angle, the erecting piece 920 is stopped. The target can then be launched.

[0055] The erecting member 920 can be any structure with sufficient supporting force and telescopic performance. This application only uses the hydraulic erecting cylinder as an example for explanation. The hydraulic erecting cylinder has a simple structure, large output force, and stable and reliable performance, ensuring that the launch box 200 rotates smoothly around the hinge point between it and the turntable 820.

[0056] Optionally, the bottom of the lower box 220 is provided with a wedge block (not shown in the figure) for guiding when docking with the erection frame 910 and a locking seat 221 for docking with the erection frame 910 to complete locking, and the erection frame 910 is provided with a wedge groove (not shown in the figure) for cooperating with the wedge block over the inclined surface. The wedge block is fixed to the rear end of the launch box 200, and the wedge groove extends along the length direction of the erection frame 910.

[0057] During hoisting, align the wedge block at the bottom of the lower box 220 with the wedge groove of the erection frame 910, and then push the launch box 200 to slide the wedge block along the wedge groove until the launch box 200 is slid to the designated position on the erection frame 910. The cooperation between the wedge block and the inclined surface of the wedge groove facilitates the installation and positioning of the launch box 200 and the erection frame 910. After the launch box 200 slides into place, the locking piece 911 on the erection frame 910 is locked with the locking seat 221 at the bottom of the lower box 220, so that the erection piece 920 drives the erection frame 910 and the launch box 200 to be erected together.

[0058] Optionally, refer to Figure 7-Figure 9A locking block 930 is provided at one end of the erecting frame 910 away from the rotating platform 820, and a limiting groove 931 is provided on the locking block 930. A limiting column 150 is provided on the launching base 100 for inserting into the limiting groove 931.
