Description

Technical Field

[0001] This utility model relates to the field of launch vehicle technology, specifically to a rocket foot support and windproof clamping device. Background Technology

[0002] With the increasing market demand for rocket launch capacity, rapid launch technology has advanced rapidly. Newer rocket models often adopt a "three-horizontal-one-vertical" launch pattern to achieve rapid launch missions. In this launch pattern, there is a certain gap between the rocket and the launch pad after it is erected, requiring the rocket foot support mechanism to actively catch the rocket feet and complete the catching action. Furthermore, wind loads can cause the rocket to sway in its vertical position, posing significant safety hazards for rocket parking and fueling. Therefore, after catching the rocket, a wind-resistant clamping mechanism is needed to reliably lock and secure the rocket feet.

[0003] However, in existing technologies, after the rocket is erected, there is still a certain spatial distance between the rocket's foot support mechanism and the rocket's feet. At this point, the foot support mechanism needs to actively adjust itself to the correct position while the rocket remains stationary to complete the rocket receiving action. This requires the foot support mechanism to have a certain degree of adjustment capability. Current devices mainly use a fixed support structure with a movable lead screw. This type of device has limited degrees of freedom and requires manual on-site operation, resulting in low efficiency and inability to adapt to rapid launch modes.

[0004] Furthermore, with the increase in the size and height of launch vehicles, the wind load on unpropelled rockets standing vertically on the launch pad becomes increasingly prominent due to their large frontal area and high center of pressure. Therefore, appropriate wind protection devices are required on the launch pad. Common wind protection devices involve securing the rocket body to the launch pad with wind-resistant bolts or using wind-resistant pressure plates to press the rocket body onto the launch pad. This type of wind protection structure requires manual installation of the wind-resistant bolts (pressure plates) after the rocket lands on the launch pad, and manual removal is also necessary after propellant loading. This approach has disadvantages such as high on-site operational difficulty, long processing time, and low safety.

[0005] In traditional rocket launches, the rocket receiving action is mostly completed by manually adjusting the lead screw, and the windproofing of the rocket feet is usually achieved by manually installing windproof bolts or windproof pressure plates. These devices are not only difficult to operate on-site and inefficient, but also have low safety. Therefore, there is an urgent need for a rocket foot support and windproofing device that is structurally sound, easy to operate, and safe and reliable. This is the problem that needs to be solved.

[0042] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this utility model by illustrating examples of it. In the accompanying drawings and the following description, at least some well-known structures and techniques have not been shown to avoid unnecessarily obscuring the utility model; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0043] like Figure 1As shown, this utility model embodiment provides a rocket foot support and windproof clamping device. The device includes a support rocker arm 1, a windproof clamping mechanism 2, a bearing mechanism 3, and a lifting adjustment mechanism 4. The bearing mechanism 3 is installed at the front end of the support rocker arm 1 and is used to support the rocket foot 7. The windproof clamping mechanism 2 is installed at the top of the support rocker arm 1 and is used to lock the rocket foot 7 onto the bearing mechanism 3. The lifting adjustment mechanism 4 is installed at the lower end of the support rocker arm 1 and is used to adjust the lifting of the support rocker arm 1.

[0044] This embodiment employs a supporting rocker arm 1 structure. The supporting rocker arm 1 is the core component and main load-bearing component of the device. Its front end is equipped with a bearing mechanism 3 to support the rocket's foot 7 structure, and its upper end is equipped with a windproof pressing mechanism 2. Using the windproof pressing mechanism 2 as the actuator, in conjunction with the lifting and adjusting mechanism 4, it can automatically achieve forward, backward, left, right, and up / down adjustments. After the rocket is erected, it can actively complete the rocket receiving action and press and lock the rocket's foot 7, improving its wind resistance in a vertical state. The rocket foot support and windproof pressing device provided in this embodiment integrates support and windproof functions. The entire device has a compact structure, can achieve rapid backward swing to avoid interference during rocket takeoff, and has multiple degrees of freedom of adjustment to adapt to different positions of the rocket's foot 7.

[0045] In some embodiments, such as Figure 2 As shown, a mounting platform 12 is provided at the front end of the upper end face of the support rocker arm 1 for mounting the bearing mechanism 3, and a mounting bracket 11 is provided at the rear end of the upper end face for mounting the windproof pressing mechanism 2; a downward first mounting part 13 is provided at the front end of the lower end face of the support rocker arm 1, and a second mounting part 14 is provided at the rear end of the lower end face. The first mounting part 13 and the second mounting part 14 are used to mount the lifting adjustment mechanism 4.

[0046] In this embodiment, the support rocker arm 1 is made of forged steel, which has a strong load-bearing capacity and can support medium and large rockets. The rear end face of its upper end is provided with a mounting bracket 11 for installing the windproof pressing mechanism 2, the front end face of its upper end is provided with a mounting platform 12 for installing the bearing mechanism 3, the entire lower end face is provided with a downward first mounting part 13, and the rear end face of its lower end is provided with a second mounting part 14. The second mounting part 14 and the first mounting part 13 are used to install the lifting and adjusting mechanism 4. Its unique structure can not only adapt to the structure of the rocket foot 7, but also achieve rapid backward swing at the moment of rocket ignition and takeoff, avoiding the swing envelope surface during rocket takeoff, thus increasing the safety of the foot and the windproof device.

[0047] In some embodiments, such as Figure 1As shown, the windproof pressing mechanism 2 includes a drive component 21, a pressing arm 22, and a pressing screw 23; one end of the pressing screw 23 is connected to the drive component 21, and the other end is connected to the pressing arm 22; the drive component 21 drives the pressing arm 22 to extend and retract through the pressing screw 23 to lock or unlock the rocket foot 7.

[0048] In this embodiment, after the rocket lands on the platform, the supporting mechanism 3 catches the rocket's arrow foot 7. The drive component 21 rotates clockwise, which drives the clamping screw 23 to extend, thereby pushing the pressure arm 22 forward to mechanically lock the rocket's arrow foot 7. After the rocket has finished fueling, the drive component 21 rotates counterclockwise, which drives the clamping screw 23 to retract, thereby pulling the pressure arm 22 backward to unlock the rocket's arrow foot 7.

[0049] In some embodiments, such as Figure 3 As shown, the bearing mechanism 3 includes an upper pressure block 31 and a lower pressure block 32; the lower pressure block 32 is fixedly installed at the front end of the supporting rocker arm 1, and a transverse sliding groove is provided at the upper end of the lower pressure block 32; the upper pressure block 31 is located at the upper end of the lower pressure block 32 and slides relative to the transverse sliding groove; the rocket foot 7 is located on the upper pressure block 31.

[0050] Specifically, the lower pressure block 32 is installed at the front end of the support rocker arm 1 by the positioning pin at the bottom and is fixed and locked by the second locking screw 34. The upper end face of the lower pressure block 32 is designed with a transverse sliding groove (the direction of the sliding groove is parallel to the axis of the first locking screw 33 and perpendicular to the movement direction of the clamping screw 23). The upper pressure block 31 is set at the upper end of the lower pressure block 32 and is fixed by the first locking screw 33. When the first locking screw 33 is not tightened, the upper pressure block 31 can slide laterally in the sliding groove on the lower pressure block 32 to adapt to the position of the rocket foot 7. After adjusting the lifting adjustment mechanism 4 to make the upper pressure block 31 fit tightly with the rocket foot 7, the first locking screw 33 is tightened to fix the position of the upper pressure block 31.

[0051] In some embodiments, such as Figure 1 As shown, the lifting adjustment mechanism 4 includes a lifting unit 41 and a rear swing adjustment unit 42. The lifting unit 41 is located at the front end of the bottom of the supporting rocker arm 1, and the rear swing adjustment unit 42 is located at the rear end of the bottom of the supporting rocker arm 1. Through the cooperation of the lifting unit 41 and the rear swing adjustment unit 42, the supporting rocker arm 1 can be raised and lowered in a horizontal state.

[0052] like Figure 1 and Figure 5 As shown, in this embodiment, by alternately controlling the lifting unit 41 and the rear swing adjustment unit 42, the support rocker arm 1 can be raised in a horizontal state until its tail is in contact with the limiting top rod 6 on the launch pad 5.

[0053] In some embodiments, the lifting unit 41 includes a lifting hydraulic cylinder 411 and a first mounting base 412; one end of the lifting hydraulic cylinder 411 is connected to the support rocker arm 1, and the other end is mounted on the mounting plane inside the rocket launch pad 5 via the first mounting base 412. The lifting hydraulic cylinder 411 can be replaced by an electric lead screw or other actuator.

[0054] In some embodiments, a limit block 413 is provided on the outside of the cylinder body of the lifting hydraulic cylinder 411, and the limit block 413 provides mechanical support for the retraction of the lifting hydraulic cylinder 411.

[0055] In this embodiment, the limiting block 413 provides mechanical restraint after the support rocker arm 1 is adjusted to the correct position. Since the lifting hydraulic cylinder 411 exhibits a certain degree of elastic recoil under load, two limiting blocks 413 are installed on the outer side of the cylinder body of the lifting hydraulic cylinder 411 before the support rocker arm 1 supports the rocket's foot 7. These blocks are then assembled with screws to provide mechanical support for the recoil of the lifting hydraulic cylinder 411, preventing it from retracting after bearing the rocket's weight and improving the safety of the device.

[0056] In some embodiments, the rear swing adjustment unit 42 includes a traction hydraulic cylinder 421 and a second mounting base 422; one end of the traction hydraulic cylinder 421 is connected to the support rocker arm 1, and the other end is mounted on the mounting plane inside the rocket launch pad 5 through the second mounting base 422.

[0057] In this embodiment, the rear swing adjustment unit 42 can not only cooperate with the lifting unit 41 to control the horizontal lifting and lowering of the support rocker arm 1, but also control the pull hydraulic cylinder 421 to quickly retract at the moment of rocket ignition and takeoff, so as to pull the support rocker arm 1 to swing backward quickly, thereby making its front end avoid the swing envelope of the rocket.

[0058] In some embodiments, the drive component 21 is a hydraulic motor, and there are two sets of hydraulic motors. In this embodiment, there are two sets of hydraulic motors, which serve as backups for each other, thus achieving redundancy in the power drive device.

[0059] The method of using the rocket support and windproof clamping device provided in this embodiment of the utility model is as follows:

[0060] The installation location of this device is as follows: Figure 5As shown, the pulling hydraulic cylinder 421 is semi-embedded in the launch pad 5 via the second mounting base 422, and the lifting hydraulic cylinder 411 is mounted in the launch pad 5 via the first mounting base 412. Before the rocket launches, the lifting hydraulic cylinder 411 and the pulling hydraulic cylinder 421 are alternately extended to keep the support rocker arm 1 horizontal and raise it until its tail is in contact with the limiting rod 6 on the launch pad 5. The limiting block 413 is fitted onto the outside of the lifting hydraulic cylinder 411 and fixed with screws. The lifting hydraulic cylinder 411 is then adjusted to retract until it presses against the limiting block 413 and then stops. The hydraulic motor is controlled to reverse, driving the clamping screw 23 to pull the rocket pressing block backward to the lowest position.

[0061] During rocket launch, the lower pressure block 32 is installed on the front end of the support rocker arm 1 via the bottom positioning pin and secured with the second locking screw 34. The upper pressure block 31 is installed on the lower pressure block 32, and the first locking screw 33 is loosened to allow it to slide. After the rocket is erected, the position of the upper pressure block 31 is adjusted according to the rocket foot 7 to ensure it is fully engaged with the rocket foot 7. Then, the first locking screw 33 is tightened to secure the upper pressure block 31. The hydraulic motor is controlled to rotate forward, driving the clamping screw 23 to extend, which in turn pushes the rocket pressure arm 22 forward to lock the rocket foot 7. After the rocket fuel is loaded, the hydraulic motor is controlled to rotate in the reverse direction, driving the clamping screw to retract and pulling the rocket pressure arm 22 backward to unlock the rocket foot 7. At the moment of rocket ignition and takeoff, the pulling hydraulic cylinder 421 is controlled to retract quickly, which can pull the support rocker arm 1 to swing rapidly backward, thus allowing its front end to avoid the rocket's swing envelope.

[0062] This embodiment has the following beneficial effects:

[0063] In this embodiment, the support rocker arm 1 is a forged part with strong load-bearing capacity, which can support medium and large rockets;

[0064] This embodiment combines the rocket foot support 7 and the windproof clamping device into one design, making the entire device more compact in structure.

[0065] This embodiment can achieve rapid backward swing and avoid interference during rocket takeoff;

[0066] This embodiment provides a new solution for supporting and windproofing the rocket's foot 7. It adds hydraulic cylinders and hydraulic motors as power devices to achieve automated adjustment, which can adapt to different positions of the rocket's foot 7 and greatly improve the efficiency when the rocket lands on the platform.
