Description

Technical Field

[0001] The invention belongs to the technical field of launch vehicles, and in particular relates to a rocket launch vehicle. Background Art

[0002] At present, rocket launchers are usually required to integrate multiple functions such as storage, transportation, loading, and launching to meet the needs of rapid response in rocket launches and improve launch efficiency; and since no other auxiliary vehicles are required during the launch process, the pressure on logistics support can be greatly reduced.

[0003] In order to provide effective protection and camouflage for the internal equipment of the launch vehicle, the launch vehicle is usually set up as a cabin structure. At the same time, in order to ensure the rapid launch of the rocket, the cabin needs to be able to open quickly and not affect the normal launch of the launch vehicle, which brings great difficulties to the overall design of the launch vehicle. Summary of the invention

[0004] The purpose of the present invention is to provide a rocket launching vehicle to solve the problems existing in the structural design of the launching vehicle.

[0005] The present invention is achieved through the following technical solutions:

[0006] Rocket launcher, including:

[0007] Cabin, set on the chassis;

[0008] Launching unit, used for launching rockets;

[0009] and / or a storage and transportation unit, arranged in the cabin, for storing rockets;

[0010] The cabin comprises a cabin bottom frame, a left hatch cover, a right hatch cover, a front cabin plate and a cabin tail door, wherein the left hatch cover and the right hatch cover are arranged opposite to each other on the cabin bottom frame and are respectively connected to the cabin bottom frame through a set of opening and closing mechanisms;

[0011] The opening and closing mechanism is used to drive the opening and closing of the left hatch cover and the right hatch cover;

[0012] When the left hatch cover and the right hatch cover are closed, they can form a closed space on the cabin bottom frame together with the front cabin plate and the cabin tail door;

[0013] When the left hatch cover and the right hatch cover are fully unfolded, they can be exactly flush with the cabin frame, and at this time, the upper ends of the left hatch cover and the right hatch cover do not exceed the sides of the cabin frame, so that the left hatch cover, the cabin frame and the right hatch cover can form a space under the cabin frame that is isolated from the launching unit.

[0014] In some embodiments of the present invention, the left hatch cover and the right hatch cover are L-shaped folding plate structures. When the left hatch cover and the right hatch cover are fully unfolded, the left hatch cover and the right hatch cover can be respectively covered on both sides of the cabin frame, and the left hatch cover and the right hatch cover form two horizontal platforms on both sides of the cabin frame.

[0015] In some embodiments of the present invention, the opening and closing mechanism includes at least one set of connecting rod driving components;

[0016] The connecting rod driving assembly comprises a mounting bracket, an active connecting rod, a driven connecting rod and a driving member, wherein the driven connecting rod is hinged to the cabin bottom frame above the cabin bottom frame at one end and is hinged to the left hatch cover or the right hatch cover at the other end;

[0017] The mounting bracket is arranged below the cabin bottom frame, one end of the active connecting rod is provided with a first hinge part and a second hinge part, the other end of the active connecting rod is hinged to the left hatch cover or the right hatch cover, and the active connecting rod is hinged to the mounting bracket at the first hinge part;

[0018] The hinge point of the driven connecting rod on the cabin bottom frame is located on the inner side of the cabin bottom frame near its side edge, so that the hinge point of the active connecting rod and the mounting bracket is arranged closer to the side edge of the cabin bottom frame than the hinge point of the driven connecting rod and the cabin bottom frame;

[0019] A four-bar linkage is formed between the active connecting rod, the driven connecting rod, the mounting bracket, the cabin bottom frame and the left hatch cover or the right hatch cover, and the hinge point between the driven connecting rod and the left hatch cover or the right hatch cover is located at a position away from the upper end of the left hatch cover or the right hatch cover;

[0020] One end of the driving member is hinged to the mounting bracket, and the other end is hinged to the second hinged portion.

[0021] In some embodiments of the present invention, when the left hatch cover and the right hatch cover are fully unfolded, the driven connecting rod abuts against the cabin bottom frame, and the active connecting rod abuts against the mounting bracket at the first hinge portion.

[0022] In some embodiments of the present invention, when the left hatch cover and the right hatch cover are closed, the active connecting rod is arranged against the inner wall of the left hatch cover or the right hatch cover.

[0023] In some embodiments of the present invention, the opening and closing mechanism includes two groups of connecting rod driving assemblies, and the two groups of connecting rod driving assemblies are respectively and correspondingly arranged at positions close to two ends of the cabin frame.

[0024] In some embodiments of the present invention, the opening and closing mechanism includes an auxiliary connecting rod, one end of which is hinged to the cabin frame, and the other end is hinged to the left hatch cover or the right hatch cover. Along the longitudinal direction of the cabin frame, the auxiliary connecting rod is located near the middle of the cabin frame and is connected to a group of driven connecting rods of a connecting rod driving assembly through a truss.

[0025] In some embodiments of the present invention, a limiting bracket for limiting the position of the connecting rod driving assembly is provided near the front deck, and when the left hatch cover and the right hatch cover are closed, the driven connecting rod abuts against the limiting bracket;

[0026] And / or, limiting members are respectively arranged on both sides of the cabin chassis to limit the position of the left hatch cover or the right hatch cover when the left hatch cover and the right hatch cover are closed.

[0027] In some embodiments of the present invention, the front cabin plate includes a fixed frame plate and two movable frame plates. The fixed frame plate is arranged on the cabin bottom frame and has a trapezoidal structure that is narrow at the top and wide at the bottom. The movable frame plates are respectively connected to the left cabin cover and the right cabin cover. When the left cabin cover and the right cabin cover are closed, a tight fit is formed at the ends between the movable frame plate and the fixed frame plate, and between the movable frame plates.

[0028] In some embodiments of the present invention, a locking assembly for locking the left hatch cover and the right hatch cover in a closed state is disposed at the top of the left hatch cover and the right hatch cover.

[0029] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0030] The present invention provides protection for the launching unit and the storage and transportation unit through the enclosed space formed by the cabin, and through the design of the cabin structure, the left hatch cover and the right hatch cover form a space that can be isolated from the launching unit in the unfolded state, so that the left hatch cover and the right hatch cover can provide protection for the equipment and tires located under the cabin frame on both sides of the cabin frame, avoiding the tail flame of the rocket from burning the equipment on the launching vehicle when the rocket is launched, thereby ensuring the launching of the launching unit at any rotation angle.

[0031] Through the design of the cabin structure, the left hatch cover and the right hatch cover can form two horizontal platforms on both sides of the cabin frame when they are unfolded. These two platforms can form two working platforms on both sides of the launch vehicle, which can provide operators with a larger operating space to facilitate the installation operation of the rocket on the launch unit.

[0032] Through the structural design of the opening and closing mechanism, the position requirements of the left and right hatch covers in the expanded state can be well met, so that the left and right hatch covers can provide effective protection for the launch vehicle, and at the same time, they can provide stable support for the left and right hatch covers in the expanded state, so that they can be used as operating platforms for operators; and based on the design of each hinged position in the connecting rod drive assembly, while realizing the control of the opening and closing state of the left and right hatch covers, the space occupied by the connecting rod drive assembly in the cabin is relatively small, which can avoid the influence of the setting of the opening and closing mechanism in the cabin on other components and units in the cabin.

[0033] Through the structural design of the opening and closing mechanism, after the cabin is unfolded, the left and right hatch covers can move to be flush with the cabin frame, so that the cabin will not have any influence on the rotation and pitch movements of the launch unit when in the unfolded state.

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0051] Generally, a rocket launcher vehicle with an integrated design integrates various functions such as storage, transportation, loading, and launching, which can realize independent launch in the field without support, so that the launcher can have good maneuverability and the ability to be quickly transported by rail and water.

[0052] Based on the needs of camouflage and protection of the launch vehicle, a closed cabin is usually set up on the launch vehicle. The cabin structure needs to respond to the needs of rapid launch of the launch vehicle to improve the launch vehicle's ability to quickly launch and withdraw.

[0053] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the rocket launcher vehicle includes:

[0054] Chassis 10;

[0055] A cabin 20, wherein the cabin 20 is disposed on the chassis 10;

[0056] A launching unit 30 for launching rockets and a storage and transportation unit 40 for storing rockets are arranged in the cabin 20 .

[0057] The cabin 20 includes a cabin bottom frame 21, a left hatch cover 22, a right hatch cover 23, a front cabin plate and a cabin tail door. The left hatch cover 22 and the right hatch cover 23 are arranged opposite to each other on the cabin bottom frame and are connected to the cabin bottom frame 21 through a set of opening and closing mechanisms respectively.

[0058] The opening and closing mechanism is used to drive the opening and closing of the left hatch cover and the right hatch cover;

[0059] When the left hatch cover and the right hatch cover are closed, they can form a closed space on the cabin bottom frame together with the front cabin plate and the cabin tail door;

[0060] When the left hatch cover and the right hatch cover are fully unfolded, they can be exactly flush with the cabin frame, and at this time, the upper ends of the left hatch cover and the right hatch cover do not exceed the sides of the cabin frame, so that the left hatch cover, the cabin frame and the right hatch cover can form a space under the cabin frame that is isolated from the launching unit.

[0061] In this embodiment, the upper ends of the left hatch cover and the right hatch cover refer to the ends that contact each other when the left hatch cover and the right hatch cover are in a closed state, and the lower ends thereof correspond to the ends that contact the cabin bottom frame.

[0062] In this embodiment, when the cabin is in the unfolded state, the left hatch cover and the right hatch cover can cooperate with the cabin base frame in position, and the left hatch cover and the right hatch cover can provide effective protection for the launch vehicle on both sides of the launch vehicle, so that the left hatch cover and the right hatch cover can play different functions in the closed and unfolded states respectively.

[0063] Usually, the launch unit 30 includes a rotary machine 31 arranged on the cabin chassis and a launcher 32 arranged on the rotary machine. The rotary machine can rotate on the cabin chassis. A pitch drive mechanism 33 for driving the launcher to pitch is arranged between the rotary machine and the launcher. At this time, the launch unit can realize the launch of the rocket at any rotation angle and pitch angle. The pitch drive mechanism can use a pitch cylinder to adjust the pitch angle of the launcher.

[0064] The tail flame produced by a rocket during launch will cause ablation to the launch vehicle. In order to reduce the impact of ablation, a protective structure that can prevent ablation needs to be set up in the area covered by the tail flame.

[0065] When the rotation angle of the rocket launch is relatively fixed, the area covered by its tail flame is also relatively easy to determine. At this time, it is only necessary to set up a protective structure at the corresponding position. However, this limits the direction of the rocket launch and makes it difficult to meet the demand for launching the rocket in any direction.

[0066] In this embodiment, the protective structure formed by the left and right hatch covers in the unfolded state can form an effective isolation between the launch vehicle parts, equipment, etc. located under the cabin and the launch unit, thereby providing protection for the launch vehicle at any rotation angle, so that the launch vehicle can meet the requirements of launching rockets at any shooting direction.

[0067] In some embodiments, the left hatch cover 22 and the right hatch cover 23 are L-shaped folding plate structures. When the left hatch cover and the right hatch cover are fully unfolded, the left hatch cover and the right hatch cover can be respectively covered on both sides of the cabin frame, and the left hatch cover and the right hatch cover form two horizontal platforms on both sides of the cabin frame.

[0068] When the left hatch cover and the right hatch cover are in the unfolded state, they can form a groove-shaped protective cover structure facing the bottom of the launch vehicle together with the cabin frame; and the upper end surfaces of the left hatch cover and the right hatch cover can form platforms on both sides of the cabin frame for operators to work, greatly expanding the operating space required for installing rockets on the launcher during launch.

[0069] In some embodiments, reference Figure 5 , Figure 6 , Figure 7 As shown, the opening and closing mechanism includes at least one set of connecting rod driving components 50;

[0070] The connecting rod driving assembly includes a mounting bracket 51, an active connecting rod 52, a driven connecting rod 53 and a driving member 54. The driven connecting rod 53 is hinged to the cabin bottom frame 21 above the cabin bottom frame at one end, and is hinged to the left hatch cover or the right hatch cover at the other end;

[0071] The mounting bracket 51 is arranged below the cabin bottom frame 21, and the active connecting rod 52 is provided with a first hinge portion 521 and a second hinge portion 522 at one end, and the other end thereof is hinged to the left hatch cover or the right hatch cover, and the active connecting rod 52 is hinged to the mounting bracket 51 at the first hinge portion 521;

[0072] The hinge point of the driven connecting rod 52 on the cabin bottom frame is located on the inner side of the cabin bottom frame near its side edge, so that the hinge point of the active connecting rod and the mounting bracket is arranged closer to the side edge of the cabin bottom frame than the hinge point of the driven connecting rod and the cabin bottom frame;

[0073] A four-bar linkage is formed between the active link 52, the driven link 53, the mounting bracket 51, the cabin bottom frame 21 and the left hatch cover 22 or the right hatch cover 23, and the hinge point between the driven link 53 and the left hatch cover 22 or the right hatch cover 23 is located at a position far away from the upper end of the left hatch cover or the right hatch cover;

[0074] One end of the driving member 51 is hinged to the mounting bracket 51, and the other end is hinged to the second hinged portion 522. In this embodiment, the driving member 51 can be a cylinder, and the cylinder drives the active connecting rod to rotate, so that the left hatch cover and the right hatch cover can be unfolded and retracted.

[0075] Reference Figure 6 Taking the connecting rod drive assembly connected to the left hatch cover as an example, the mounting bracket, active connecting rod, driven connecting rod, cabin base frame and left hatch cover in the connecting rod drive assembly form a four-bar mechanism. When the active connecting rod is driven to rotate by the driving member, the four-bar mechanism can drive the left hatch cover to move, thereby realizing the expansion and closure of the left hatch cover.

[0076] The present invention not only needs to realize the deployment and folding of the left and right hatch covers, but also hopes that they can cooperate with the cabin chassis to form a protective structure in the deployed state, and that there should be no interference with the cabin chassis during the deployment and folding processes, and that there should be no interference with the movement of the launcher after deployment, and that a good closed fit should be formed between the left and right hatch covers and the cabin chassis after folding. These put forward very high requirements on the structure of the connecting rod drive assembly and the design of the connection position between the connecting rod drive assembly and the cabin chassis.

[0077] Taking the driving structure of the left hatch cover as an example, in this embodiment, a mounting bracket is arranged under the cabin frame, the active connecting rod is hinged to the mounting bracket, the driven connecting rod is hinged to the cabin frame, and the hinge point between the driven connecting rod and the cabin frame is arranged on the inner side of the hinge point between the active connecting rod and the mounting bracket; and the hinge point between the driven connecting rod and the left hatch cover is arranged at a position away from the upper end of the left hatch cover. Taking the L-shaped left hatch cover structure as an example, at this time, the hinge points of the driven connecting rod, the active connecting rod and the left hatch cover are respectively located at the corner positions close to the L-shaped structure of the left hatch cover, so that when the left hatch cover is in a fully expanded state, the driven connecting rod and the active connecting rod are basically stored in the left hatch cover, so that the upper end of the left hatch cover can be located on the inner side of the side of the cabin frame.

[0078] Based on the above optimization of the structure of the connecting rod drive assembly, the requirements for realizing the above functions are well met during the process of unfolding and closing the right hatch cover.

[0079] In some embodiments, when the left hatch cover and the right hatch cover are fully unfolded, the driven connecting rod 53 abuts against the cabin bottom frame 21, and the active connecting rod 52 abuts against the mounting bracket 51 at the first hinge portion 521. At this time, it can not only provide a limit for the action of the connecting rod driving assembly in the unfolded state, but also provide strong support for the driven connecting rod and the active connecting rod, thereby ensuring the stability of the left hatch cover and the right hatch cover when used as a working platform.

[0080] In some embodiments, when the left hatch cover and the right hatch cover are closed, the active connecting rod 52 is arranged against the inner wall of the left hatch cover 22 or the right hatch cover 23, so that when the left hatch cover and the right hatch cover are in the closed state, the active connecting rod 52 can be stored in the cabin, and the space occupied by the connecting rod drive assembly in the cabin is reduced.

[0081] In some embodiments, the opening and closing mechanism includes two sets of connecting rod drive assemblies 50, and the two sets of connecting rod drive assemblies 50 are respectively arranged at positions close to the two ends of the cabin chassis. The left hatch cover and the right hatch cover are respectively connected to the cabin chassis through the two sets of connecting rod drive assemblies, and the opening and closing of the left hatch cover and the right hatch cover are controlled, which can ensure the overall structural strength of the cabin and the structural strength when used as a platform.

[0082] In some embodiments, the opening and closing mechanism includes an auxiliary link 55, one end of the auxiliary link 55 is hinged to the cabin frame 21, and the other end is hinged to the left hatch cover 22 or the right hatch cover 23. Along the longitudinal direction of the cabin frame 21, the auxiliary link 55 is located near the middle of the cabin frame and is connected to a set of driven links 53 in a link drive assembly through a truss 56.

[0083] By providing multiple sets of connecting rod drive assemblies and auxiliary connecting rods, the ability of the opening and closing mechanism to drive and control the left and right hatch covers can be increased, thereby ensuring the stability of the opening and closing action of a large cabin.

[0084] In some embodiments, a limit bracket 28 for limiting the position of the connecting rod driving assembly is provided near the front deck. When the left hatch cover and the right hatch cover are closed, the driven connecting rod abuts against the limit bracket 28.

[0085] Limiting members 29 are respectively arranged on both sides of the cabin bottom frame 21, so as to limit the position of the left hatch cover or the right hatch cover when the left hatch cover and the right hatch cover are closed.

[0086] In some embodiments, the front cabin plate includes a fixed frame plate 24 and two movable frame plates 25. The fixed frame plate 24 is set on the cabin base frame 21 and has an isosceles trapezoidal structure that is narrow at the top and wide at the bottom. The movable frame plates 25 are respectively connected to the front ends of the left cabin cover and the right cabin cover.

[0087] When the left hatch cover and the right hatch cover are closed, a tight fit is formed between the movable frame plate and the fixed frame plate, and between the movable frame plates at the end portions. At this time, the movable frame plate and the fixed frame plate jointly form the front hatch plate.

[0088] The cabin tail door comprises a left tail door 26 hinged with the left hatch cover and a right tail door 27 hinged with the right hatch cover, so as to facilitate the opening and closing of the left hatch cover and the right hatch cover. A lock catch is arranged on the left tail door and the right tail door for locking the cabin tail door.

[0089] In some embodiments, a locking assembly 60 is disposed at the top of the left hatch cover and the right hatch cover for locking the left hatch cover and the right hatch cover in a closed state.

[0090] Reference Figure 8 The locking assembly 60 includes two lock heads 61 arranged on the left hatch cover and a lock seat 62 arranged on the right hatch cover. A lock rod 63 is rotatably connected to the right hatch cover through the lock seat 62. The lock rod 63 is provided with a lock tongue 64 that can form a locking match with the lock head. When the lock rod is rotated to form a clamping connection between the lock tongue and the lock head, the locking assembly can limit the movement of the left hatch cover and the right hatch cover in the deployment direction, and realize the locking between the left hatch cover and the right hatch cover; when the lock rod is rotated in the opposite direction, the connection between the lock tongue and the lock head is released, and the left hatch cover and the right hatch cover can be unlocked at this time.

[0091] The launch vehicle in this embodiment integrates functions such as storage, loading, and launching. The length of the entire vehicle is within 11m, the width is within 2.6m, and the height is within 3.5m, which can facilitate independent transportation of the launch vehicle and has good transfer capabilities.

[0092] The launch vehicle integrates functions such as positioning and orientation, manual / automatic leveling, automatic aiming, rocket hoisting / loading, constant temperature storage and transportation of rockets, vibration monitoring and alarm, etc. It can achieve large shooting angle and high-precision launch, and has excellent camouflage and protection functions.

[0093] After the launch vehicle arrives at the launch site, the launch vehicle support is leveled, the cabin is unlocked and unfolded, and the launcher is rotated 180° by the rotary machine;

[0094] The operator opens the storage and transportation unit on the unfolded left and right hatch covers, and hoists the rockets in the storage and transportation unit onto the launcher through the lifting equipment 11 on the launch vehicle and locks and installs them;

[0095] Control the rotary machine and the pitch drive mechanism to adjust the launcher to the set launch angle and enter the launch state.

[0096] The expansion process of the cabin is:

[0097] Unlock the cabin tailgate;

[0098] Unlock the left and right hatch covers;

[0099] The actions of the driving parts in each group of connecting rod driving assemblies are controlled to fully unfold the left hatch cover and the right hatch cover.

[0100] The unfolded left and right hatch covers can provide a working platform for the operator, while also providing protection for the launch vehicle, allowing the rocket to be launched from different angles.

[0101] Similarly, by driving the connecting rod drive components through the driving parts, the cabin can be quickly closed. At the same time, the positions of the left and right hatch covers in the closed state are limited by the limiting brackets and limiting parts to ensure that the left and right hatch covers have good centering in the closed state and the overall rigidity of the cabin is guaranteed.

[0102] Based on the mechanical design of the opening and closing mechanism, while the cabin meets the above-mentioned storage, transportation, launching, opening and closing, protection and other performances, the overall size of the cabin is small and does not exceed the size of the wheeled chassis, which can well meet the requirements of road, rail and sea transportation.

[0103] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. used to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship commonly placed when the product of the invention is used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0104] In addition, if the terms "horizontal" or "vertical" appear in the description of the present invention, it does not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0105] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0106] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
