DETAILED DESCRIPTION

[0020] 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.

[0021] Those skilled in the art will appreciate 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 presence of the features, integers, steps, operations, elements and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components and / or combinations thereof 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" may be implemented as "A", or as "B", or as "A and B".

[0022] 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.

[0023] In the related art, the guide rail is located at the top of the guide beam, and the slider of the target is located at the bottom of the target. Since the guide rail is short, when loading, a reserved loading port is often used or the target is hoisted from the front of the guide rail, and then a thrust is applied along the axial direction of the target to push the target in. Therefore, a separate hoist is required to hoist the target onto the rack. After the target is loaded, it is located above the guide beam. When the target is launched, multiple groups of sliders of the target leave the guide rail at the same time, and the target will fall to a certain extent due to its gravity, which will shorten the safe distance between the slider at the bottom of the target and the guide beam, resulting in lower launch safety.

[0024] To solve the above technical problems, refer to Figure 1-Figure 9 The embodiment of the present application provides a zero-length launching device, including a launching base 100 detachably arranged from top to bottom, an erecting and rotating mechanism 400, a supporting frame 200 and a guiding beam 300.

[0025] Reference Figure 1 and Figure 2The guide beam 300 includes a guide beam body 310 extending along the length direction of the support frame 200 and at least two guide rails 320 located below the guide beam body 310, and the guide rails 320 are used to combine with the slider at the top of the target 900. A suspension point 330 is arranged above the guide beam body 310. In the present application, three suspension points 330 are spaced apart along the length direction of the guide beam body 310, including a front suspension point 331, a middle suspension point 332, and a rear suspension point 333 arranged in sequence. Among them, the size of the middle suspension point 332 is larger than the size of the front suspension point 331 and the rear suspension point 333.

[0026] Reference Figure 1 , Figure 3-Figure 4 The support frame 200 has an open space extending along its length. Before launching, the target 900 is mounted below the guide beam body 310 and is located in the space enclosed by the support frame 200.

[0027] In the present application, the guide rail 320 is arranged below the guide beam body 310, and a suspension point 330 is arranged above the guide beam body 310. When the target 900 is loaded, the guide beam 300 is lifted by connecting the lifting device with the suspension point 330, and then the guide rail 320 located below the guide beam 300 is combined and locked with the slider at the top of the target 900, so that the loading of the target 900 is more convenient, and there is no need to use a dedicated loading device, which saves the equipment cost in the early stage of development.

[0028] After the target 900 is loaded, it is mounted below the guide beam body 310 and is located in the space surrounded by the support frame 200. It should be noted that the distance between the target 900 and the bottom surface of the launch frame is set large enough in the present application.

[0029] During launch, the slider on the top of the target 900 slides along the guide rail 320 until it leaves the rail at the same time, and the target 900 falls under the influence of gravity and increases the distance from the guide beam 300. In this way, even if the target 900 falls to a certain extent, it can avoid friction with the guide beam 300 and the support frame 200, thereby improving the launch safety.

[0030] At the same time, the guide beam 300 of the present application not only undertakes mounting, but also undertakes guiding and lifting functions, and has a high degree of integration, which can effectively reduce the volume of the zero-length launch device; the launch base 100, the erecting and rotating mechanism 400, the support frame 200 and the guide beam 300 of the present application are all configured to be detachable for easy assembly and maintenance.

[0031] Reference Figure 2Optionally, the guide beam body 310 is H-shaped, including a skeleton 311 and connecting frames 312 at both ends, the connecting frames 312 are used to be erected on the support frame 200 and connected to the support frame 200, at least two guide rails 320 are arranged at both ends of the skeleton 311, and are constructed to be located below the connecting frames 312.

[0032] The guide beam body 310 is fixed to the support frame 200 through the connecting frames 312 at both ends. The connecting frames 312 extend along the width direction of the support frame 200, so as to facilitate the guide beam body 310 to be stably installed above the support frame 200. In the present application, the two ends of the connecting frame have connecting shafts 3121; the four corners of the top of the support frame are equipped with a lower locking seat 220 and an upper locking seat 210 detachably connected to the lower locking seat 220, and the connecting shaft 3121 is inserted and locked in the fixing hole formed by the lower locking seat 220 and the upper locking seat 210 to achieve the fixing of the guide beam body 310 and the support frame 200. At least two guide rails 320 are located at both ends of the skeleton 311 and below the connecting frame 312 to ensure the stability of the target 900 when it is mounted below the guide beam 300.

[0033] Optionally, the four columns at the four corners of the support frame 200 are all provided with handrails 240, and a plurality of handrails 240 are arranged at intervals along the height direction of the columns to facilitate the hoisting and disassembly of the support frame 200. The support frame 200 is also provided with an ignition cable hook fixing hole 250, and the ignition cable can be connected to the ignition cable hook fixing hole 250 according to the situation when the target 900 is launched.

[0034] Optionally, refer to Figure 2 The frame 311 is arched and includes a main body 3111 and connecting parts 3112 at both ends of the main body 3111. The height of the main body 3111 is higher than that of the connecting parts 3112 and the connecting frame 312.

[0035] The present application takes two guide rails 320 as an example for explanation, and the two guide rails 320 are located below the connecting portion 3112. When the target 900 is mounted below the guide beam body 310, the height of the main body 3111 of the frame 311 is designed to be higher than the height of the connecting portion 3112, thereby increasing the distance between the target 900 and the guide beam body 310, avoiding friction between the target 900 and the guide beam body 310 when launching, and improving the launch safety.

[0036] Reference Figure 1 and Figure 2 Optionally, a positioning antenna 500 is provided at the connection point between the skeleton 311 and each connecting frame 312 .

[0037] By arranging the positioning antennas 500 at the front and rear ends of the target 900, when the target 900 is mounted below the guide beam 300, the connection line of the two positioning antennas 500 coincides with the axis of the target 900. When the launch azimuth of the target 900 is adjusted by the erection and rotation mechanism 400, the two positioning antennas 500 are used to detect the azimuth of the target 900, so as to facilitate adjusting the target 900 to a predetermined azimuth.

[0038] Reference Figure 4 Optionally, the zero-length launch device of the present application further includes a disengagement detection mechanism 600 disposed at the front end of the support frame 200. The disengagement detection mechanism 600 is located on one side of the support frame 200, and includes a support rod 610 and a laser sensor 620 movably disposed on the support rod 610. The support rod 610 extends along the length direction of the support frame 200. The position of the laser sensor 620 on the support rod 610 is adjustable, and is electrically connected to the control system of the zero-length launch device. The laser sensor 620 is movably disposed on the support rod 610, so that the position of the laser sensor 620 can be flexibly adjusted after the target 900 is loaded, so that the laser sensor 620 can be aligned with the detached plug 910 of the target 900, so as to detect whether the detached plug 910 falls off from the target 900 after the target 900 is launched. In practical applications, the laser sensor 620 can be slidably disposed on the support rod 610, or magnetically disposed on the support rod 610, which is not limited in the present application.

[0039] In the present application, the laser sensor 620 is a diffuse reflection laser sensor. After adjusting the laser sensor 620 to align with the detached plug 910 on the target 900, when the laser beam emitted by the laser sensor 620 is irradiated onto the detached plug 910, the laser beam will be reflected by the surface of the detached plug 910. The reflected laser beam is received by the receiver in the laser sensor 620 and transmitted to the control system. When the target 900 emits but the detached plug 910 does not fall off smoothly from the target 900, that is, the detached plug 910 leaves the initial position together with the target 900, the laser beam emitted by the laser sensor 620 cannot be irradiated onto the detached plug 910, and the laser sensor 620 cannot receive the signal reflected by the detached plug 910, thereby judging whether the detached plug 910 has fallen off smoothly from the target 900.

[0040] Reference Figure 4 Optionally, the zero-length launch device of the present application further includes an auxiliary plug-out mechanism 700 disposed at the front end of the support frame 200. The auxiliary plug-out mechanism 700 includes a fixed pulley 710 rotatably disposed at the front end of the support frame 200, a traction rope 720 having one end passing around the fixed pulley 710 and used to connect to the drop plug 910 of the target 900, and a counterweight 730 connected to the other end of the traction rope 720.

[0041] When the drop-off plug 910 is controlled to bounce away from the target 900, the gravity of the counterweight 730 is used to separate the drop-off plug 910 from the target 900, thereby ensuring that the drop-off plug 910 smoothly drops off the target 900 when the target 900 is launched.

[0042] Reference Figure 1 and Figure 4-Figure 7 Optionally, the erecting and rotating mechanism 400 includes a rotating component 410 for adjusting the azimuth angle of the support frame 200 and an erecting component 420 for adjusting the pitch angle of the launch frame.

[0043] The rotating assembly 410 includes a rotating table 411 rotatably disposed on the launching base 100 and a crank slider structure (not shown in the figure) for driving the rotating table 411 to rotate.

[0044] A crank slider structure is used as a structure for adjusting the launch azimuth angle of the support frame 200 and the target 900. The staff can manually or the system can automatically control the slider in the crank slider structure to drive the slewing bearing 120, the turntable 411, the erection assembly 420, the support frame 200 and the target 900 to rotate in the vertical direction together, and adjust the target 900 to rotate to the predetermined launch azimuth angle according to the real-time detection of the positioning antenna 500.

[0045] Reference Figure 5 Optionally, the launching base 100 includes a base body 110 and a slewing bearing 120 disposed on the base body 100 , and the turntable 411 is installed on the slewing bearing 120 , so that the turntable 411 can slew in a vertical direction.

[0046] A locking member 412 for locking with the launch base 100 is installed on the turntable 411. In the present application, the locking member 412 is a fixed leg arranged around the turntable 411.

[0047] Optionally, refer to Figure 4 or Figure 6 The erecting assembly 420 includes an erecting frame 421 which is arranged obliquely and hinged at one end to the turntable 411, a driving member 422 for driving the erecting frame 421 to rotate in a vertical plane, and a transmission member 423 arranged therebetween.

[0048] One end of the erection frame 421 is hingedly arranged on the turntable 411 through the mounting frame 424, and the other end is mounted on the support seat 425 installed on the turntable 411 and extending in the height direction and locked with the top of the support seat 425 through the movable bolt 426. The height of the support seat 425 is higher than the height of the mounting frame 424, so that the erection frame 421 is in an inclined state with one end higher and the other end lower. The transmission member 423 and the driving member 422 are both arranged in the space between the erection frame 421 and the turntable 411. The support frame 200 is detachably arranged on the top of the erection frame 421 through the movable bolt 426, and the top of the erection frame 421 is also fixed with a guide column 4211 extending in the vertical direction, and the bottom of the support frame is provided with a guide seat 230 with a socket for matching with the guide column 4211, so that the support frame 200 is aligned and locked with the erection frame 421.

[0049] Optionally, refer to Figure 6 or Figure 7 The transmission member 423 includes a horizontally extending slide rail 4231, a slide seat 4232 slidably disposed on the slide rail 4231, and a supporting link 4233 hinged between the slide seat 4232 and the erecting frame 421. The driving member 422 is drivingly connected to the driving slide seat 4232.

[0050] The supporting link 4233 is used to obliquely support the erection frame 42. When the driving member 422 drives the sliding seat 4232 to slide along the slide rail 4231, the inclination angle between the supporting link 4233 and the horizontal plane gradually increases, so that the supporting link 4233 gradually stands upright, thereby driving the erection frame 421, the supporting frame 200 and the target 900 to gradually stand upright to a predetermined pitch angle.

[0051] Optionally, refer to Figure 6 and Figure 7 The driving member 422 includes a spiral lifting structure 4220, which is mounted on the turntable 411 through two front and rear mounting seats 427. The lead screw 4221 of the spiral lifting structure 4220 is rotatably connected with the sliding seat 4232 and drives the sliding seat 4232 to slide along the length direction of the lead screw 4221. A rotating wheel 4223 is mounted on one end of the worm 4222 of the spiral lifting structure 4220.

[0052] When adjusting the pitch angle of the target 900 , the staff can rotate the rotating wheel 4223 manually or with an electric wrench, thereby driving the lead screw 4221 to slide forward, thereby driving the sliding seat 4232 to slide along the slide rail 4231 .

[0053] The rotation of the support frame 200 and the target 900 is achieved by a crank slider mechanism, and the erection is achieved by a screw elevator. The azimuth and pitch angles can be adjusted manually or automatically, without the need for off-site power supply guarantee, and can flexibly cope with off-site power supply failures.

[0054] Reference Figure 8-Figure 9 Optionally, the zero-length launch device further includes an inclinometer fixing fine-tuning mechanism 800 disposed on the support frame 200. The inclinometer fixing fine-tuning mechanism 800 includes a base plate 810 mounted on the bottom of the support frame 200, a flip plate 820 whose first end is hinged on the base plate 810, an adjustment bolt 830 connected between the base plate 810 and the second end of the flip plate 820, and an inclinometer sensor (not shown in the figure) mounted on the flip plate 820 on the side away from the base plate 810. The flip plate 820 rotates with a pin 840 parallel to the width direction of the support frame 200 as the central axis.

[0055] By turning the adjustment bolt 830 and utilizing the real-time feedback of the inclination sensor, the initial inclination angle of the launch can be finely adjusted to ensure that the initial inclination angle of the launch of the front support frame 200 is at zero position.

[0056] The present application also provides a method for launching a target 900 based on the zero-length launch device in the above embodiment. Fig.10 , a method for launching a target 900 includes steps S101-S106.

[0066] Reference Figure 2 Optionally, the combination of the guide beam 300, the support frame 200 and the target 900 is lifted by the front lifting point 330, the middle lifting point 330 and the rear lifting point 330 above the guide beam 300, and then the length of the lifting chain of the front lifting point 330 is shortened by a hand winch to raise the front of the support frame 200 to the initial elevation angle, and finally the combination is lifted onto the erecting and rotating mechanism 400 and fixed by the movable bolt 426.

[0067] S106: Adjust the pitch angle and azimuth angle of the support frame 200 and ignite and launch the target 900.

[0068] After the engine is ignited, the front slider on the target 900 moves in the front rail 320 of the guide beam 300, and the rear slider moves in the rear rail 320 of the guide beam 300. After moving a short distance, the front slider and the rear slider simultaneously leave the front and rear rails 320 of the launcher, realizing the inclined thermal launch of the target 900.

[0069] Reference Figure 4 , Figure 6 and Figure 7 Optionally, in the above step S106, adjusting the pitch angle and azimuth angle of the support frame 200 includes: The crank slider structure is pushed to rotate the turntable 411 and the support frame 200 , the guide beam 300 and the target 900 thereon in a vertical direction, so that the support frame 200 , the guide beam 300 and the target 900 rotate to a predetermined azimuth angle.

[0070] The erecting and rotating mechanism 400 includes a rotating assembly 410 and an erecting assembly 420 . The rotating assembly 410 includes a crank slider structure and a rotating table 411 . The erecting assembly 420 includes a screw elevator 4220 and a transmission member 423 .

[0071] The spiral lift 4220 is manually adjusted by the rotating wheel 4223, and the transmission member 423 is used to erect the support frame 200, the guide beam 300 and the target 900 to a predetermined pitch angle.

[0072] Optionally, after the adjustment is completed, the turntable 411 and the base body 110 are quickly locked using the locking member 412 .

[0073] The front end of the support frame 200 is also equipped with a disconnection detection mechanism 600 and an auxiliary disconnection mechanism 700. Optionally, after the combination of the guide beam 300, the target 900 and the support frame 200 is hoisted onto the erection and rotation mechanism 400, and before the pitch angle and azimuth angle of the support frame 200 are adjusted, it also includes: The laser sensor 620 of the disconnection detection mechanism 600 is adjusted so that the light spot of the laser sensor 620 is aligned with the center position of the disconnected plug 910 .

[0074] The auxiliary plug-in and detachment mechanism 700 is installed, and one end of the traction rope 720 of the auxiliary plug-in and detachment mechanism 700 is connected to the counterweight 730 , and the other end is connected to the detachment plug 910 of the target 900 .

[0075] The beneficial technical effects brought about by the technical solution provided by the embodiment of the present application include: the present application sets the guide rail 320 below the guide beam body 310, and after loading, the target 900 is mounted below the guide beam body 310 and is located in the space surrounded by the support frame 200. When the slider of the target 900 separates from the guide rail 320 and falls under the influence of gravity, the distance from the guide beam 300 will be increased, thereby avoiding friction between the target 900 and the guide beam 300 and the support frame 200 during the launch process, thereby improving the launch safety.

[0076] A lifting point 330 is provided above the guide beam body 310. When the target 900 is loaded, the guide beam 300 is lifted by connecting the lifting equipment to the lifting point 330, and then the guide rail 320 located below the guide beam 300 is combined and locked with the slider at the top of the target 900, so that the target 900 is mounted below the guide beam body 310. The guide beam 300 of the present application not only bears the functions of mounting, but also bears the functions of guiding and lifting, and has a high degree of integration, which can effectively reduce the volume of the zero-length launch device.

[0077] The launching base 100, the erecting and rotating mechanism 400, the supporting frame 200 and the guide beam 300 of the present application are all configured to be detachable for easy assembly and maintenance.

[0078] The present application sets a disconnection detection mechanism 600, which emits a laser beam through a laser sensor 620 to generate diffuse reflection with the disconnected plug 910 on the target 900, and generates a feedback signal with the receiver of the laser sensor 620, so as to judge whether the disconnected plug 910 is successfully disconnected after the target 900 is launched. An auxiliary disconnection mechanism 700 is set to assist the disconnected plug 910 to disconnect from the target 900, so as to ensure the smooth launch of the target 900.

[0079] The rotation of the support frame 200 and the target 900 is achieved by a crank slider mechanism, and the erection is achieved by a screw elevator. The azimuth and pitch angles can be adjusted manually without external power supply guarantee, and the situation of external power supply failure can be flexibly dealt with.

[0080] By arranging an inclinometer fixing fine-tuning mechanism 800 on the support frame 200, the initial inclination angle of the support frame 200 can be fine-tuned by screwing the adjusting bolt 830, thereby ensuring that the launch inclination angle before erection is at zero position.
