Technical Field
[0001] The present invention relates to the field of rocket launching technology, and in particular to a gas protection door and rocket launching equipment. Background Art
[0002] During the mobile vertical hot launch of a carrier rocket, the general process is that the rocket launch equipment is moved into position, the hatch and gas protection door of the rocket launch equipment are opened, and the carrier rocket is erected from a horizontal state to a vertical state under the drive of the erection equipment and docked with the launch pad. Then, the erection arm of the erection equipment returns to a horizontal state without load, the hatch and gas protection door are closed, and the carrier rocket is ignited and launched.
[0003] During the launch of a carrier rocket, the hatch and gas protection door cover and seal the launch vehicle to prevent the rocket gas flow from impacting and damaging the equipment on the launch vehicle. In order to resist the impact of the rocket gas flow, the gas protection door near the tail of the rocket is generally made of high-strength steel and needs to have good sealing performance and the ability to resist the scouring of the rocket gas flow.
[0004] Since the launch vehicle is erected on the launch pad, due to space limitations, the gas protection door cannot be made into an integral opening and closing door structure, nor can it be sealed with an up-and-down flipping structure. At present, the gas protection doors of existing rocket launch equipment are mostly equipped with left and right doors. The left and right doors are based on a connecting rod mechanism to achieve translational expansion and contraction to both sides to achieve the purpose of opening and closing the door. However, due to the use of a two-door superimposed compression mode, and considering the structural complexity of the connecting rod mechanism, this method has the problems of difficult to ensure the structural strength of the gas baffle, loose closing of the door, and the rocket gas flow easily entering the cabin to damage electronic components, which makes it difficult to meet the high-density and rapid launch requirements of space launch vehicles.

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] Combine the following Figure 1-Figure 13 , the gas protection door and rocket launching equipment provided by the embodiments of the invention are described in detail through specific embodiments and their application scenarios.
[0022] In the first aspect, Figure 1 As shown, an embodiment of the present invention provides a gas protection door, the gas protection door 1 comprises: a flip bracket 11 and a gas damper 12; The flip bracket 11 is configured to be rotatably disposed on one side of the hatch 20 of the rocket capsule 2, and can be switched between a first state and a second state relative to the rocket capsule 2; the gas damper 12 is movably disposed on the flip bracket 11 along the extension direction of the flip bracket 11; When the flip bracket 11 is in the first state, the flip bracket 11 is arranged parallel to the guide rail 201 at the hatch 20, and the gas baffle 12 can move between the flip bracket 11 and the guide rail 201 to control the opening and closing of the hatch 20; when the flip bracket 11 is in the second state, the flip bracket 11 and the gas baffle 12 are arranged close to the side wall of the rocket cabin 2, and the flip bracket 11 can be connected to the side wall of the rocket cabin 2 by using a locking member.
[0023] It can be understood that the gas baffle 12 and the flip bracket 11 are both made of high-strength steel, the gas baffle 12 has a good ability to resist the erosion of rocket gas flow, and one end of the flip bracket 11 is rotatably installed on one side of the hatch 20 of the rocket cabin 2, and can rotate around the vertical axis relative to the rocket cabin 2.
[0024] Optionally, when the flip bracket 11 switches from the first state to the second state, the flip bracket 11 rotates 90° around the first rotation direction relative to the rocket capsule 2; correspondingly, when the flip bracket 11 rotates 90° around the second rotation direction relative to the rocket capsule 2, the flip bracket 11 switches from the second state to the first state. The rotation directions corresponding to the first rotation direction and the second rotation direction are opposite.
[0025] Optionally, the flip bracket 11 can be a rectangular bracket and is configured to be distributed vertically, with the length side of the flip bracket 11 arranged parallel to the horizontal plane; the extension direction of the flip bracket 11 is along the length direction of the flip bracket 11, and the gas baffle 12 can move horizontally relative to the flip bracket 11 along the extension direction of the flip bracket 11.
[0026] Optionally, during the movement of the gas baffle 12 relative to the flip bracket 11, the gas baffle 12 and the flip bracket 11 can be connected by a rolling fit or a sliding fit; the gas baffle 12 and the flip bracket 11 can be connected by a telescopic rod, and the telescopic rod drives the gas baffle 12 to move relative to the flip bracket 11; of course, the gas baffle 12 can also be manually driven to move relative to the flip bracket 11.
[0027] As can be seen from the above, the gas protection door 1 shown in the present invention is provided with a flip bracket 11 and a gas damper 12. When used for rocket launch and the launch vehicle 6 is erected, the flip bracket 11 can be rotated to the first state, and the gas damper 12 can be controlled to translate from the hatch 20 to the flip bracket 11 (see Figure 4 ), and then rotate the flip bracket 11 from the first state to the second state close to the side wall of the rocket cabin 2 (see Figure 6 ), so as to provide a smooth rotation channel for the erection of the carrier rocket 6; after the erection of the carrier rocket 6 is completed, the flip bracket 11 can be switched to the first state, and then the gas damper 12 can be controlled to move from the flip bracket 11 to the hatch 20 to close and seal the hatch 20 (see Figure 5 ), which can effectively withstand high-temperature, high-speed rocket gas during launch of the carrier rocket 6, and prevent the rocket gas from entering the rocket cabin 2 from the hatch 20.
[0028] Compared with the existing double-opening or flip-up gas protection door 1, the gas protection door 1 shown in the present invention is not only simple in structure, but also can control the opening and closing of the hatch 20 of the rocket cabin 2 in a limited space, and can ensure the sealing effect of the hatch 20 when closing the hatch 20 of the rocket cabin 2, thereby effectively solving the problem that the gas generated during rocket launch can easily enter the rocket cabin 2, thereby causing damage to the electronic components in the rocket cabin 2.
[0029] In some embodiments, Figure 1 and Figure 2 As shown, the flip bracket 11 includes a frame 111 and a first roller set 112; one end of the frame 111 is rotatably disposed on a first vertical side of the hatch 20; the first roller set 112 is rotatably disposed on a side of the frame 111 facing the gas damper 12; A slide rail 123 is disposed on one side of the gas baffle 12 facing the frame 111 . The slide rail 123 is extended along the sliding direction of the gas baffle 12 and is movably disposed on the first roller assembly 112 along the sliding direction.
[0030] It is understandable that the frame 111 can be made of high-strength steel pipes. The frame 111 can be configured to include a rectangular frame and a "M"-shaped bracket. The "M"-shaped bracket is arranged on the inner side of the rectangular frame and connected to the rectangular frame. The rectangular frame and the "M"-shaped bracket are both assembled from high-strength steel pipes.
[0031] A hinge seat 113 is provided at the first end of the frame 111, and the frame 111 is connected to the first vertical side of the hatch 20 via the hinge seat 113, so that the frame 111 can rotate around the vertical axis relative to the rocket cabin 2.
[0032] The slide rail 123 on the gas baffle 12 can be a grooved track, and the groove end of the grooved track is configured to face one side of the frame 111; the first roller group 112 includes multiple rollers, each of which is arranged in the cavity of the grooved track, and the rollers can be polyurethane wheels or ball bearings.
[0033] Among them, one end of the groove track close to the hinge seat 113 is designed to be closed, and one end of the groove track away from the hinge seat 113 is designed to be open.
[0034] Based on the rolling contact between the slide rail 123 and the first roller assembly 112 , the contact friction force when the gas damper 12 translates relative to the flip bracket 11 is reduced, making it easier for operators to manually drive the gas damper 12 to move relative to the flip bracket 11 .
[0035] In some embodiments, Figure 2 and Figure 3 As shown, there are multiple slide rails 123, which are arranged in sequence from top to bottom; the first roller group 112 includes multiple groups of roller units, which are arranged in sequence from top to bottom, and the multiple groups of roller units and the multiple slide rails 123 are matched one by one.
[0036] It can be understood that each group of roller units includes a plurality of rollers, and the rollers of each group are arranged along the sliding direction of the gas baffle 12 .
[0037] By providing a plurality of roller units and a plurality of slide rails 123 that cooperate with each other one by one, the stability and reliability of the translation of the gas baffle 12 relative to the flip bracket 11 are ensured.
[0038] In some embodiments, Figure 1 and Figure 2 As shown, a support leg 114 is provided on a side of the frame 111 facing away from the gas baffle 12 ; when the flip bracket 11 is in the second state, the support leg 114 is configured to be supported on the side wall of the rocket cabin 2 .
[0039] Specifically, the support leg 114 is disposed at one end of the frame 111 away from the hinge seat 113. The support leg 114 may be configured to include a connecting rod and a chassis, one end of the connecting rod is connected to the frame 111, and the other end is connected to a first end surface of the chassis, and the second end surface of the chassis is configured to contact the side wall of the rocket cabin 2.
[0040] Among them, a flexible pad can be set on the second end face of the chassis, for example, the flexible pad is a silicone pad. This design can prevent the flip bracket 11 from rigidly contacting the side wall of the rocket cabin 2 during the process of switching the flip bracket 11 from the first state to the second state.
[0041] When the flip bracket 11 is in the second state, since the support legs 114 are supported between the frame 111 and the side walls of the rocket capsule 2, the frame 111 and the side walls of the rocket capsule 2 can be set in parallel. This design not only ensures the aesthetic layout of the frame 111, but also facilitates the alignment of the locking structure of the frame 111 and the locking structure on the side wall of the rocket capsule 2, so that the frame 111 can be locked to the side wall of the rocket capsule 2 using a locking piece.
[0042] In some embodiments, Figure 1 and Figure 3 As shown, the gas baffle 12 includes a baffle body 121 and a second roller assembly 122; the baffle body 121 is movably disposed on the flip bracket 11 along the extension direction of the flip bracket 11; The second roller set 122 is disposed on a side of the baffle body 121 facing the flip bracket 11 and close to the lower edge of the baffle body 121 . The second roller set 122 is used to support the baffle body 121 to move along the guide rail 201 .
[0043] It is understandable that the second roller group 122 includes a plurality of rollers, and the plurality of rollers are arranged along the extension direction of the flip bracket 11 , and each roller can be a polyurethane wheel or a ball bearing.
[0044] Based on the rolling contact between the second roller set 122 and the guide rail 201 , it can be ensured that the baffle body 121 can move relative to the hatch 20 along the extension direction of the flip bracket 11 , so that the baffle body 121 can close or open the hatch 20 .
[0045] At the same time, since the second roller group 122 is arranged on the side of the baffle body 121 facing the flip bracket 11, and the setting height of the second roller group 122 is higher than the lower edge of the baffle body 121, when the baffle body 121 closes the hatch 20, it can be ensured that there is no gap between the lower edge of the baffle body 121 and the lower edge of the hatch 20. This design is beneficial to ensuring the sealing effect of the baffle body 121 on the hatch 20 when the baffle body 121 closes the hatch 20.
[0046] In some embodiments, Figure 1 and Figure 3 As shown, the gas baffle 12 further includes an operating handle 124 , and the operating handle 124 is disposed on at least one side of the baffle body 121 along the moving direction of the baffle body 121 .
[0047] Specifically, Figure 1 As shown, the operating handle 124 is disposed on a side of the baffle body 121 away from the hinge seat 113. In actual application, the operator can hold the operating handle 124 to drive the baffle body 121 to move toward the side close to the hatch 20, thereby controlling the gas baffle 12 to move from the flip bracket 11 to the guide rail 201, and then use the baffle body 121 to close the hatch 20; the operator can hold the operating handle 124 to drive the baffle body 121 to move toward the side away from the hatch 20, thereby controlling the hatch 20 to be opened, and then controlling the gas baffle 12 to move from the guide rail 201 to the flip bracket 11.
[0048] When the baffle body 121 closes the hatch 20 , a locking member may be used to connect the baffle body 121 with the locking structure at the hatch 20 .
[0049] In some embodiments, Figure 3 As shown, in order to ensure the sealing of the gas baffle 12 and improve the impact resistance to the rocket gas flow, the baffle body 121 includes a high-strength steel plate 1211 and a steel frame 1212; the steel frame 1212 is mesh-shaped and is arranged on a side of the high-strength steel plate 1211 facing the flip bracket 11; The second roller set 122 is disposed at the bottom of the steel frame 1212 , and a height difference is formed between the second roller set 122 and the bottom edge of the high-strength steel plate 1211 .
[0050] In some embodiments, Figure 1As shown, in order to control the movement of the gas baffle 12 relative to the flip bracket 11, the gas baffle 12 is provided with a first limit member 1201, and the flip bracket 11 is provided with a second limit member 1101; in the process of the gas baffle 12 moving along the guide rail 201 and closing the hatch 20, the first limit member 1201 can abut against the second limit member 1101 to prevent the gas baffle 12 from continuing to move toward the side away from the flip bracket 11.
[0051] Specifically, the first limit member 1201 can be arranged on a side of the baffle body 121 facing the flip bracket 11, the first limit member 1201 can be a limit pin, and the second limit member 1101 can be a slot; when the gas baffle 12 closes the hatch 20, the limit pin is locked in the slot; when the gas baffle 12 opens the hatch 20, the limit pin can be disengaged from the slot.
[0052] In the second aspect, Figures 7 to 13 As shown, an embodiment of the present invention further provides a rocket launching device, which includes: a rocket cabin 2, an erecting device 3, a launching platform 4 and the gas protection door 1 as described above; The rocket capsule 2 includes a base 21 and a hatch 22, and the hatch 22 is rotatably arranged on the upper side of the base 21; the erection device 3 is arranged on the base 21 and is located in the corresponding accommodation space of the rocket capsule 2; The rear end of the base 21 is open to form a hatch 20 ; the launching platform 4 is disposed on one side of the hatch 20 , and the flip bracket 11 of the gas protection door 1 is rotatably disposed on one side of the hatch 20 .
[0053] It is understandable that the rocket capsule 2 and the launch pad 4 are usually configured to be disposed on a movable vehicle body 5, that is, the rocket capsule 2 and the launch pad 4 are both vehicle-mounted equipment.
[0054] The rocket cabin 2 forms a storage space for accommodating the carrier rocket 6. The storage space is a heat-insulating space. The hatch 22 can be rotated relative to the base 21 under the drive of the hydraulic system to open or close the storage space. The erection device 3 has an erection arm. The erection device 3 drives the carrier rocket 6 to switch from a horizontal state to a vertical state through the erection arm, thereby completing the erection operation of the carrier rocket 6.
[0055] Since the rocket launching equipment includes the gas protection door 1, and the specific structure of the gas protection door 1 refers to the above-mentioned embodiment, the rocket launching equipment of this embodiment includes all the technical solutions of the above-mentioned embodiment, and therefore has at least all the beneficial effects achieved by all the technical solutions of the above-mentioned embodiment, which will not be described one by one here.
[0056] The scheme shown in this embodiment is described below in conjunction with the operational process of launching a carrier rocket 6 based on a rocket launching device.
[0057] like Figure 7 As shown, after the carrier rocket 6 completes the final assembly test in the technical final assembly plant, the carrier rocket 6 is placed in the rocket cabin 2 and transported to the launch site by the rocket launch equipment. At this time, the flip bracket 11 of the gas protection door 1 can be unlocked to ensure that the flip bracket 11 and the side wall of the rocket cabin 2 are separated, so as to prepare for the opening operation of the gas protection door 1.
[0058] like Figure 8 As shown, at the launch site, the hatch 22 of the rocket cabin 2 is controlled to open, and at the same time, the flip bracket 11 is rotated 90° in the clockwise direction until the flip bracket 11 is switched to the first state, so that the flip bracket 11 is arranged parallel to the guide rail 201 at the hatch 20.
[0059] like Fig. 9 As shown, the operator manually drives the gas damper 12 to move from the hatch 20 to the flip bracket 11 to open the hatch 20 of the rocket cabin 2.
[0060] like Fig.10 and Fig.11 As shown, the flip bracket 11 is rotated 90° in the counterclockwise direction, so that the flip bracket 11 drives the gas baffle 12 to switch to the second state, and the flip bracket 11 is connected to the side wall of the rocket cabin 2; at the same time, the erection arm of the erection device 3 is controlled to flip upward, and the erection device 3 drives the carrier rocket 6 to switch from a horizontal state to a vertical state through the erection arm until the carrier rocket 6 stands vertically on the launch pad 4, thereby completing the erection operation of the carrier rocket 6.
[0061] like Fig.12 As shown, after the erection operation of the carrier rocket 6 is completed, the erection arm of the erection device 3 is controlled to return to the horizontal position without load, and the hatch 22 of the rocket cabin 2 is controlled to close.
[0062] like Fig.13 As shown, the flip bracket 11 is rotated 90° in the clockwise direction, and the flip bracket 11 is switched to the first state, so that the flip bracket 11 is arranged parallel to the guide rail 201 at the hatch 20; then, the gas damper 12 is manually driven to translate from the flip bracket 11 to the hatch 20 to close the hatch 20 of the rocket cabin 2, and when the gas damper 12 is closed in place, the gas damper 12 is locked to the hatch 20 of the rocket cabin 2 by a locking member; finally, the flip bracket 11 is rotated 90° in the counterclockwise direction, so that the flip bracket 11 is switched to the second state, and the flip bracket 11 is connected to the side wall of the rocket cabin 2. At this time, the hatch cover 22 and the gas damper 12 enclose the erection device 3 in the closed rocket cabin 2, and the tail flame generated during the rocket launch will not directly wash the erection device 3, thereby avoiding the tail flame generated during the rocket launch from damaging the erection device 3.
[0063] Furthermore, if Figure 4 and Figure 6 As shown, the hatch 20 has a first vertical side and a second vertical side, and the guide rail 201 is arranged on the lower side edge of the hatch 20; the flip bracket 11 is rotatably arranged on the first vertical side, and the second vertical side is provided with a limit slot 202, and the limit slot 202 is clamped with the vertical side of the gas baffle 12; At the same time, a first slide groove 203 is provided at the top of the first vertical side, and a second slide groove 204 is provided at the top of the second vertical side. The lateral side of the upper side of the gas damper 12 can be movably inserted into the first slide groove 203 and the second slide groove 204.
