DETAILED DESCRIPTION

[0046] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0047] The embodiments of the present application will be described below in combination with Figures 1 to 7 .

[0048] ​According to embodiments of this application, in one aspect, an engine compartment section is provided, such as... Figure 1 As shown, it includes a mounting bracket 1, a support bracket 2, a first cylindrical body 3, and a second cylindrical body 4. The bottom of the mounting bracket 1 is provided with a mounting part, which is used to connect the engine.

[0049] The support frame 2 is connected to the top of the mounting frame 1 and is also connected inside the first cylinder 3. The mounting frame 1 is located at the bottom of the first cylinder 3 and is connected to the first cylinder 3.

[0050] The second cylinder 4 is detachably connected to the bottom of the first cylinder 3. After the top of the engine is connected to the mounting part, the engine is hoisted onto the mounting bracket 1, at which time the engine is located inside the second cylinder 4.

[0051] During engine installation, the first cylinder 3 can be hoisted, and then the second cylinder 4 can be detached from the bottom of the first cylinder 3. At this point, the bottom of the first cylinder 3 is completely open, allowing the engine to be transported to the bottom of the first cylinder 3 and installed from any angle to connect the engine to the mounting portion on the mounting bracket 1. The first cylinder 3 is then hoisted to lift the engine. The second cylinder 4 is then rotated to be underneath the engine, and the first cylinder 3 is lowered to allow the engine to descend into the second cylinder 4. The top of the second cylinder 4 aligns with the bottom of the first cylinder 3. Finally, the top of the second cylinder 4 is connected to the bottom of the first cylinder 3 to complete the installation.

[0052] This design allows the second cylinder 4 to be detached before engine installation, completely opening the lower part of the first cylinder 3. When the engine is installed at the bottom of the first cylinder 3, the second cylinder 4 will not interfere with the engine installation, providing the user with greater operating space. This allows the user to install the engine from any angle, making operation more convenient.

[0053] The top of the second cylinder 4 and the bottom of the first cylinder 3 can be fixed with bolts; that is, bolt holes are provided at both the top of the second cylinder 4 and the bottom of the first cylinder 3. After aligning the second cylinder 4 and the first cylinder 3, and aligning the bolt holes at the top and bottom of the second cylinder 4, the bolts are passed through the bolt holes at the top of the second cylinder 4 and the bottom of the first cylinder 3 in sequence, and then secured with nuts. To disassemble the second cylinder 4 and the first cylinder 3, the nuts are unscrewed, and the bolts are pulled out of the bolt holes at the top of the second cylinder 4 and the bottom of the first cylinder 3 in sequence, thus separating the second cylinder 4 and the first cylinder 3.

[0054] The first cylinder 3 may include a conical section and a cylindrical section, with the conical section located above the cylindrical section and the bottom of the cylindrical section being detachably connected to the top of the second cylinder 4.

[0055] In one embodiment, as shown in Figures 2 to 4 The mounting rack 1 includes a middle beam, a connecting beam 15, a first mounting member 11 and a plurality of second mounting members 12. The bottom of the first mounting member 11 and the second mounting member 12 is provided with a mounting portion. Each second mounting member 12 is uniformly arranged along the circumference of the first mounting member 11.

[0056] The middle beam is provided with a plurality of middle beams, and each second mounting member 12 is connected to the first mounting member 11 by a middle beam. Thus, each middle beam plays a connecting and reinforcing role between the second mounting member 12 and the first mounting member 11.

[0057] The connecting beam 15 is provided with a plurality of connecting beams, and each second mounting member 12 is connected to the first cylinder 3 by a connecting beam 15.

[0058] In this way, for each second mounting member 12, one side is connected to the first cylinder 3 by the connecting beam 15, and the other side is connected to the first mounting member 11 by the middle beam, so that each second mounting member 12 is arranged around the first mounting member 11, and the first mounting member 11 is fixed at the middle position by the middle beam. For the first mounting member 11 and the second mounting member 12, the mounting portion provided at the bottom can mount the engine, thereby realizing the loading of multiple engines. At the same time, the mounting rack 1 has a disc-shaped structure, and the radial bearing capacity and the circumferential bearing capacity are stronger.

[0059] The mounting portion can be a flange plate, which is used to butt joint the connecting flange provided on the engine.

[0060] Specifically, the second mounting member 12 is provided with eight second mounting members, the connecting beam 15 is provided with eight connecting beams, and the middle beam is provided with eight middle beams. The eight second mounting members 12 are arranged around the first mounting member 11, so that a total of nine engines can be mounted, and the mounting rack 1 has a symmetrical shape, which ensures the overall stability.

[0061] The middle beam can be connected to the connecting beam 15 as a whole, so that the overall bearing capacity is stronger.

[0062] In some embodiments, the mounting rack 1 further includes a reinforcing beam 16, and one reinforcing beam 16 is connected between each adjacent two second mounting members 12, thereby enhancing the bearing capacity of the second mounting member 12 and making the overall structure of the mounting rack 1 have stronger bearing capacity.

[0063] The reinforcing beam 16 can be C-shaped.

[0064] In one embodiment, as shown in Figure 2 and Figure 3 The plurality of middle beams includes a plurality of first middle beams 13 and a plurality of second middle beams 14.

[0065] The first intermediate beams 13 are evenly and spacedly arranged along the circumference of the first mounting member 11, and one second intermediate beam 14 is arranged between every two adjacent first intermediate beams 13. The first intermediate beam 13 has two connecting ends, one of which is connected with the first mounting member 11, and the other of which is connected with a second mounting member 12.

[0066] The second intermediate beams 14 are evenly and spacedly arranged along the circumference of the first mounting member 11, and one first intermediate beam 13 is arranged between every two adjacent second intermediate beams 14. The second intermediate beam 14 has three connecting ends, the first connecting end of which is connected with the second mounting member 12, the second connecting end of which is connected with one first intermediate beam 13 adjacent thereto, so as to be connected with the first mounting member 11 through the first intermediate beam 13, and the third connecting end of which is connected with another first intermediate beam 13 adjacent thereto, so as to be connected with the first mounting member 11 through the first intermediate beam 13.

[0067] In this way, the connection relationship is established between the first intermediate beams 13 and the second intermediate beams 14, so that the overall bearing capacity of the mounting rack 1 is stronger. Moreover, the second intermediate beam 14 has the connection relationship with the two first intermediate beams 13 adjacent thereto, further enhancing the bearing capacity.

[0068] Specifically, the first mounting member 11 and the second mounting member 12 are arranged in a cross shape, and have four connecting ends evenly arranged along the circumference of the mounting member. The eight intermediate beams include four first intermediate beams 13 and four second intermediate beams 14.

[0069] The first intermediate beam 13 is a straight-through type, and the two ends thereof are the two connecting ends. The four connecting ends of the first mounting member 11 are connected with the four first intermediate beams 13 respectively, and the ends of the four first intermediate beams 13 away from the first mounting member 11 are connected with the connecting ends of one second mounting member 12 respectively. The connecting ends of the four second mounting members 12 away from the first intermediate beams 13 are connected with the first cylinder 3 through the connecting beams 15.

[0070] The connecting end of the first mounting member 11 is fixed with the connecting end of the first intermediate beam 13 by a bolt. The connecting end of the first intermediate beam 13 is fixed with the connecting end of the second mounting member 12 by a bolt, and the connecting end of the second mounting member 12 is fixed with the connecting beam 15 by a bolt.

[0071] The second intermediate beam 14 is a tee type, and has three connecting ends, i.e. a Y shape. For the four second intermediate beams 14, the first connecting end of each second intermediate beam 14 is connected with the connecting end of one second mounting member 12, and the connecting ends of the four second mounting members 12 away from the second intermediate beams 14 are connected with the first cylinder 3 through the connecting beams 15.

[0072] The second connecting end of each second intermediate beam 14 is connected with an adjacent first intermediate beam 13, and the third connecting end of each second intermediate beam 14 is connected with another adjacent first intermediate beam 13.

[0073] The connecting end of the second intermediate beam 14 is fixed with the first intermediate beam 13 by a bolt, and the connecting end of the second intermediate beam 14 is fixed with the connecting end of the second mounting member 12 by a bolt.

[0074] For the remaining two connecting ends of the second mounting member 12, one connecting end of the second mounting member 12 is connected with the other connecting end of the second mounting member 12 through the reinforcing beam 16, so that the second mounting members 12 are sequentially connected into a ring shape through the reinforcing beam 16.

[0075] The two ends of the reinforcing beam 16 are fixed with the connecting ends of the second mounting members 12 by bolts.

[0076] In an embodiment, as shown in Figure 5 The support frame 2 comprises a ring-shaped beam 22 and a plurality of rib frames 21. Each rib frame 21 is uniformly arranged along the circumference of the first cylinder 3 and uniformly arranged along the circumference of the ring-shaped beam 22, and the ring-shaped beam 22 is coaxially arranged with the first cylinder 3.

[0077] Each rib frame 21 is connected with the first cylinder 3 on the side close to the first cylinder 3, and each rib frame 21 is connected with the ring-shaped beam 22 on the side away from the first cylinder 3. Each rib frame 21 is connected with a part of the intermediate beams one by one, or each rib frame 21 is connected with a part of the connecting beams 15 one by one, or each rib frame 21 is connected with a part of the intermediate beams one by one and a part of the connecting beams 15 one by one.

[0078] In this way, each rib frame 21 establishes a connection reinforcement between the top of the mounting frame 1 and the first cylinder 3, so that the connection between the mounting frame 1 and the first cylinder 3 is more stable, and the axial bearing capacity of the mounting frame 1 is enhanced.

[0079] Moreover, each rib frame 21 is arranged along the circumference of the ring-shaped beam 22 and connected with the ring-shaped beam 22, so that the ring-shaped beam 22 establishes a connection relationship between the rib frames 21. Each rib frame 21 is supported by the ring-shaped beam 22, so that the structure of each rib frame 21 is more stable.

[0080] The rib frame 21 is fixed with the first cylinder 3 by a bolt, the rib frame 21 is fixed with the intermediate beam by a bolt, the rib frame 21 is fixed with the connecting beam 15 by a bolt, and the rib frame 21 is fixed with the ring-shaped beam 22 by a bolt.

[0081] A plurality of reinforcing ribs are arranged in the rib frame 21 to increase the strength of the rib frame 21.

[0082] Since the ribs 21 are uniformly arranged along the circumference of the first cylinder 3, spaces for the engine pipelines to pass through are formed between the ribs 21. Since the intermediate beams are uniformly arranged along the circumference of the first cylinder 3, spaces for the engine pipelines to pass through are formed between the intermediate beams.

[0083] In one embodiment, as shown in FIG. 2, the support frame 2 further comprises a plurality of support arms 23. The top ends of the support arms 23 are connected to the bottom of the annular beam 22, and the ends of the support arms 23 away from the annular beam 22 are connected to the mounting frame 1. Thus, the support arms 23 establish a connection relationship between the annular beam 22 and the mounting frame 1, further supporting the mounting frame 1 and enhancing the load-bearing capacity of the mounting frame 1. Figure 5

[0084] The support arms 23 are fixed to the annular beam 22 by bolts, and the support arms 23 are fixed to the mounting frame 1 by bolts.

[0085] In one embodiment, as shown in FIG. 2, the mounting frame 1 further comprises a connecting piece 17 and a reinforcing piece 18. The ends of the intermediate beams away from the second mounting piece 12 are respectively connected to the connecting piece 17, so that the connecting piece 17 establishes a connection relationship between the intermediate beams, further enhancing the load-bearing capacity of the mounting frame 1. Figure 4 Moreover, the reinforcing piece 18 is connected between the first mounting piece 11 and the connecting piece 17, so that the reinforcing piece 18 establishes a connection relationship between the first mounting piece 11 and the connecting piece 17, further enhancing the load-bearing capacity of the first mounting piece 11.

[0086] The ends of the support arms 23 away from the annular beam 22 are connected to the connecting piece 17, realizing the connection of the support arms 23 and the mounting frame 1.

[0087] The connecting piece 17 can be a cylinder, the top of the cylinder is connected to the connecting piece 17, and the bottom of the cylinder is connected to the first mounting piece 11.

[0088] Specifically, the connecting piece 17 is arranged in a cross shape, and has four connection ends uniformly arranged along the circumference of the connecting piece 17. The four connection ends of the connecting piece 17 are respectively connected to the four first intermediate beams 13.

[0089] The connection ends of the connecting piece 17 and the connection ends of the first intermediate beams 13 are fixed by bolts.

[0090] The support arms 23 are arranged in four, the top portions of the four support arms 23 are respectively connected to the top portions of the annular beam 22, and the four support arms 23 are uniformly arranged along the circumference of the annular beam 22. The bottom portions of the four support arms 23 are respectively connected to the top portions of the four connection ends of the connecting piece 17. While realizing the connection of the support arms 23 and the mounting frame 1, the load-bearing capacity of the first mounting piece 11 is increased.

[0091] The connection ends of the connecting piece 17 and the connection ends of the first intermediate beams 13 are fixed by bolts.​

[0092] In one embodiment, as shown in Figure 1 and Figure 6 The first cylinder body 3 comprises a first cylindrical frame 31 and a first skin 32 surrounding the first cylindrical frame 31. The first cylindrical frame 31 comprises a first lower annular frame 311, a first upper annular frame 312 and a plurality of first vertical beams 313.

[0093] The first vertical beams 313 have top ends and bottom ends. The top ends of the first vertical beams 313 are connected to the first upper annular frame 312 respectively, and the bottom ends of the first vertical beams 313 are connected to the first lower annular frame 311 respectively. The first skin 32 surrounds the first cylindrical frame 31, thereby forming the first cylinder body 3.

[0094] The second cylinder body 4 is detachably connected to the bottom of the first lower annular frame 311, and the first upper annular frame 312 is used to connect with other cabin sections of the rocket.

[0095] Some of the first vertical beams 313 are connected to the ribbed frame 21 one by one to form an integral whole, so that the connection between the ribbed frame 21 and the first cylinder body 3 is more stable.

[0096] The second cylinder body 4 is detachably connected to the bottom of the first lower annular frame 311 by bolts.

[0097] In some embodiments, the mounting frame 1 comprises a connecting beam 15 connected to the first lower annular frame 311, so as to realize the connection between the connecting beam 15 and the first cylinder body 3.

[0098] The connecting beam 15 is fixed to the first lower annular frame 311 by bolts.

[0099] In one embodiment, as shown in Figure 6 The first cylindrical frame 31 further comprises a plurality of cross beams 314. For two adjacent first vertical beams 313, one end of a cross beam 314 is connected to one first vertical beam 313, and the other end of the cross beam 314 is connected to the other first vertical beam 313. In this way, one cross beam 314 is connected between each two adjacent first vertical beams 313, and the cross beam 314 plays a connecting and reinforcing role between the two adjacent first vertical beams 313, so that the overall strength of the first cylindrical frame 31 is higher.

[0100] The cross beams 314 and the first vertical beams 313 are fixed by bolts.

[0101] In one embodiment, as shown in Figure 6As shown, each of the adjacent two first vertical beams 313 forms an opening 3131, so that the user can enter the first cylinder 3 through the opening 3131. Wherein the opening 3131 has a plurality of openings, and each group of adjacent two first vertical beams 313 forms an opening 3131.

[0102] In this way, when the engine is installed on the mounting portion of the mounting frame 1, and the pipeline is connected to the engine, the pipeline is inserted from the top of the first cylinder 3, passes through the inside of the first cylinder 3, and then passes through the mounting frame 1 and is connected to the engine. In this process, the user can enter the first cylinder 3 through the opening 3131 to support the inserted pipeline to assist the pipeline connection to the engine.

[0103] Moreover, when the engine needs to be maintained or the air pressure needs to be detected, the user can also enter the first cylinder 3 through the opening 3131, which makes the operation more convenient.

[0104] The top of the first skin 32 is detachably connected with the first upper annular frame 312, and the bottom of the first skin 32 is detachably connected with the first lower annular frame 311. At this time, the first skin 32 will seal each opening 3131. When the first skin 32 is removed, each opening 3131 will be exposed.

[0105] In this way, under normal circumstances, the first skin 32 will seal each opening 3131, and when it is necessary to enter the first cylinder 3, the first skin 32 can be removed to expose each opening 3131. After the operation is completed, the first skin 32 can be connected with the first upper annular frame 312 and the first lower annular frame 311 again.

[0106] The bottom of the first skin 32 is detachably connected with the first lower annular frame 311 by bolts, and the top of the first skin 32 is detachably connected with the first upper annular frame 312 by bolts.

[0107] Wherein the opening 3131 is provided with eight openings, and the first skin 32 can include eight skin members, each of which is detachably connected with the first upper annular frame 312 and the first lower annular frame 311. And each skin member corresponds to seal one opening 3131.

The second cylindrical frame 41 includes a second lower annular frame 411, a second upper annular frame 412, and a plurality of second vertical beams 413.

[0109] The second vertical beam 413 has a top end and a bottom end. The top end of each second vertical beam 413 is connected with the second upper annular frame 412 respectively, and the bottom end of each second vertical beam 413 is connected with the second lower annular frame 411 respectively. The second vertical beam 413 is connected between the second upper annular frame 412 and the second lower annular frame 411 to form the whole second cylindrical frame 41. The second skin 42 is arranged around the periphery of the second cylindrical frame 41 to form the whole second cylinder 4. The second upper annular frame 412 is detachably connected with the first lower annular frame 311.
