[0002] In the related art, during the docking process of rocket cabins, the two cabins that need to be docked and assembled are placed horizontally on corresponding support structures respectively, and the support structures are driven to bring the two cabins close to complete the docking.

[0003] However, due to the complex structure of the cabin and the large number of parts involved, the docking and assembly process of the cabin is difficult, the assembly workload is large, and the assembly efficiency is low. In addition, when two adjacent cabins are docked, the two cabins cannot be completely aligned, which further increases the difficulty of docking the rocket cabins, reduces the assembly efficiency, and has low assembly accuracy. Summary of the invention

[0005] This application is implemented as follows:

[0006] An embodiment of the present application provides a rocket compartment that can improve assembly accuracy and assembly efficiency, including at least two sub-compartments, wherein two adjacent sub-compartments respectively have a first end face and a second end face corresponding to each other, the first end face is provided with at least two guide protrusions, and the second end face is provided with a guide groove corresponding to the guide protrusions one by one; the guide protrusion has a first guide surface, and the guide groove has a second guide surface, and the first guide surface and the second guide surface are both smooth curved surfaces; during the docking process of two adjacent sub-compartments, the first guide surface can contact the second guide surface to push the guide protrusion to move along its radial direction so that the axis of the guide protrusion overlaps with the axis of the guide groove.

DETAILED DESCRIPTION

[0026] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0027] During the docking process of two adjacent rocket sections, since the two sections cannot be completely aligned, structural errors and deformations need to be repeatedly adjusted, resulting in greater assembly difficulty, low assembly efficiency and low assembly accuracy.

[0028] The inventors have found that when the rocket compartment is placed horizontally on the support structure, the support structure can only contact part of the compartment due to the large overall size of the compartment. Affected by gravity, the compartment will deform during the horizontal placement process. The farther the compartment is from the support structure, the weaker the support effect and the more serious the deformation, resulting in the inability to fully align the two adjacent compartments during docking.

[0029] In view of this, the embodiment of the present application provides a rocket compartment section that can improve assembly accuracy and assembly efficiency, referring to Figures 1 to 8As shown, the rocket compartment includes at least two sub-compartments 10. Between two adjacent sub-compartments 10, the two sub-compartments 10 respectively have a first end face 100 and a second end face 200 corresponding to each other. Mutually corresponding means that after the rocket compartment is docked, the first end face 100 and the second end face 200 are in contact and matched with each other.

[0030] The first end surface 100 is provided with at least two guide protrusions 300, and the second end surface 200 is provided with guide grooves 400 corresponding to the guide protrusions 300. The guide protrusions 300 can be snapped into the corresponding guide grooves 400 to limit the relative position of the first end surface 100 and the second end surface 200, thereby preventing the two adjacent sub-compartments 10 from rotating relative to each other. The guide protrusions 300 have a first guide surface 310, and the guide grooves 400 have a second guide surface 410, and both the first guide surface 310 and the second guide surface 410 are smooth curved surfaces.

[0031] During the docking process of two adjacent sub-compartments 10, as the two sub-compartments 10 approach each other, the guide protrusion 300 first enters the plane where the second end surface 200 is located. When the structure of the sub-compartment 10 is not deformed, the axis of the guide protrusion 300 and the axis of the corresponding guide groove 400 overlap, and as the sub-compartment 10 moves, the guide protrusion 300 is directly inserted into the guide groove 400 along its axial direction. After the guide protrusion 300 is assembled in place in the guide groove 400, the first guide surface 310 will contact the second guide surface 410.

[0032] However, due to the influence of gravity, the sub-compartment 10 will be deformed. Therefore, in the case of deformation of the sub-compartment 10, the axis of the guide protrusion 300 and the axis of the corresponding guide groove 400 are usually staggered with each other, that is, in the docking process of the two sub-compartments 10, before the guide protrusion 300 and the guide groove 400 are assembled in place, the first guide surface 310 of the guide protrusion 300 will contact the second guide surface 410 of the guide groove 400. Since both guide surfaces are smooth curved surfaces, during the contact process between the first guide surface 310 and the second guide surface 410, a force will act on the guide protrusion 300 along its radial direction, so that the guide protrusion 300 has a component of moving along its radial direction, and the relative position of the guide protrusion 300 and the guide groove 400 is adjusted, so that the axis of the guide protrusion 300 overlaps with the axis of the guide groove 400, the deformation of the sub-compartment 10 is corrected, and the docking assembly between the two sub-compartments 10 is completed.

[0033] During the docking process of the two sub-compartments 10, the deformation of the sub-compartment 10 can be corrected by the contact between the guide protrusion 300 and the guide groove 400 without additional correction. The docking assembly efficiency is high, and the difficulty of the docking assembly is correspondingly reduced and the assembly accuracy is correspondingly improved.

[0034] The guide protrusion 300 is disposed on the first end surface 100, referring to Figure 6 and Figure 7 As shown, the number of guide protrusions 300 is at least two, and at least two guide protrusions 300 can correct the deformation of the sub-compartment 10. The more the number of guide protrusions 300 is, the better the deformation correction effect of the sub-compartment 10 is. However, the number of guide protrusions 300 cannot be too many. On the one hand, too many will increase the manufacturing cost and difficulty of the sub-compartment 10. At the same time, the number of guide grooves 400 corresponding to the guide protrusions 300 will also increase. Too many guide grooves 400 will affect the structural strength of the sub-compartment 10 provided with the guide grooves 400. In actual implementation, the guide protrusions 300 are generally set to four or six.

[0035] The guide groove 400 is disposed on the second end surface 200, referring to Figure 4 and Figure 5 As shown, the number and positions of the guide grooves 400 are arranged in a one-to-one correspondence with the guide protrusions 300 .

[0036] The first guide surface 310 of the guide protrusion 300 is its outer surface, and the first guide surface 310 is generally arranged around the axis of the guide protrusion 300 to contact the second guide surface 410 in its circumferential direction, thereby providing a radial force or a radial force component to the guide protrusion 300. The second guide surface 410 of the guide groove 400 is its inner wall surface, corresponding to the first guide surface 310, and the second guide surface 410 is also arranged around the axis of the guide groove 400 to facilitate contact and cooperation with the first guide surface 310.

[0037] It can be understood that a smooth curved surface means that there are no edges or corners on the curved surface, each point on the curved surface has a tangent plane, and the direction of the tangent plane changes continuously with the continuous change of the points on the curved surface. When the first guide surface 310 and the second guide surface 410 are in contact, the two guide surfaces can slide relative to each other, and the smooth curved surface will not hinder their sliding.

[0038] In some preferred embodiments, the guide protrusion 300 and the guide groove 400 can be set to a rotationally symmetrical structure. Even if the guide protrusion 300 and the guide groove 400 are offset, the first guide surface 310 and the second guide surface 410 can be stably fitted after contact, which is more conducive to providing a force for the guide protrusion 300 and driving the guide protrusion 300 to move along its radial direction. In some specific embodiments, the outer surface of the guide protrusion 300 and the inner wall surface of the guide groove 400 can be a part of the surface of a spherical structure, or can be the surface of an ellipsoid or other structure that can form a smooth curved surface.

[0039] In some specific embodiments, the two ends of a sub-compartment 10 can be docked with the other two sub-compartments 10, and the two ends of the sub-compartment 10 can be respectively provided with a guide protrusion 300 and a guide groove 400, or both can be provided with a guide protrusion 300 or both can be provided with a guide groove 400. In other specific embodiments, the sub-compartment 10 can be provided with only a guide protrusion 300 or a guide groove 400, which is determined according to the actual position of the sub-compartment 10 in the rocket compartment.

[0040] During the assembly process of the sub-compartment 10, the sub-compartment 10 is horizontally placed on the compartment support structure 30. Fig.11 and Fig.12 As shown, two adjacent cabin support structures 30 are brought close to each other so as to dock and assemble two sub-cabins 10. In addition, during the process of the two cabin support structures 30 approaching each other, the cabin support structure 30 can also drive the sub-cabin 10 to rotate, adjust the circumferential position of the sub-cabin 10, adjust the position and posture of the sub-cabin 10, adjust the structural error and deformation, and make it easier to dock the two sub-cabins 10.

[0041] In some embodiments of the present application, the circumferential side wall of the sub-compartment 10 includes a support segment 500 for contacting the compartment support structure 30. When the sub-compartment 10 is placed on the compartment support structure 30, the support segment 500 of the sub-compartment 10 contacts the compartment support structure 30, which may be point contact or surface contact, or both point contact and surface contact exist at the same time, and the point contact and surface contact parts are both located within the range of the support segment 500.

[0042] When the sub-compartment 10 is placed on the compartment support structure 30, the portion in direct contact with the compartment support structure 30 is supported more strongly and is less likely to deform than other portions of the sub-compartment 10. The portion of the sub-compartment 10 that is not in direct contact with the compartment support structure 30 is suspended in the air and is more affected by gravity and is more likely to deform.

[0043] In this regard, in some embodiments of the present application, when the sub-compartment 10 is horizontally placed on the compartment support structure 30, that is, when the compartment support structure 30 supports the sub-compartment 10, on the cross section of the sub-compartment 10, the distance between the guide protrusion 300 and the support section 500 in the gravity direction is set as a first distance, and along the growth direction of the first distance, the protrusion height of the guide protrusion 300 gradually decreases. The farther away from the support section 500, the lower the protrusion height of the guide protrusion 300, and the closer to the support section 500, the higher the protrusion height of the guide protrusion 300, refer to Fig.11 and Fig.12 shown.

[0044] The sub-compartment 10 close to the compartment support structure 30 has less deformation or almost no deformation. When the two sub-compartments 10 are docked with each other, the guide protrusion 300 provided in this part first enters into the guide groove 400 to correct the deformation of the sub-compartment 10, and then the guide protrusion 300 gradually away from the compartment support structure 30 gradually enters into the corresponding guide groove 400 to gradually correct the deformation of the sub-compartment 10.

[0045] In some embodiments provided by the present application, the deformation of the sub-compartment 10 is corrected gradually from the part with the smallest deformation to the part with the largest deformation. The part with a smaller deformation is less difficult to correct and is easier to correct. In addition, in the process of correcting the part with a smaller deformation, the sub-compartment 10 will be gradually straightened to reduce the overall deformation of the sub-compartment 10. Correspondingly, the deformation of the part with a larger deformation of the sub-compartment 10 will also be reduced, making it easier for the guide protrusion 300 of this part to be snapped into the guide groove 400, thereby further correcting the deformation of the sub-compartment 10 and reducing the difficulty of correcting the deformed part of the sub-compartment 10.

[0046] The deformation of the sub-compartment 10 far from the compartment support structure 30 is relatively large. If the protrusion height of the corresponding guide protrusion 300 is relatively high, the guide protrusion 300 will first enter the range of the corresponding second end surface 200. However, due to the large deformation of the sub-compartment 10 at this position, the misalignment distance between the guide protrusion 300 and the guide groove 400 may be relatively large, and the guide protrusion 300 may not enter the range of the corresponding guide groove 400, resulting in the guide protrusion 300 being unable to dock with the corresponding guide groove 400. Therefore, the greater the deformation of the sub-compartment 10, the lower the protrusion height of the corresponding guide protrusion 300.

[0047] In some preferred embodiments, when the sub-compartment 10 is placed on the compartment support structure 30, the part of the sub-compartment 10 with a larger deformation, that is, the part with a larger first distance, has a larger radial dimension of the corresponding guide protrusion 300. Since the deformation of the sub-compartment 10 is large, the corresponding offset distance between the guide protrusion 300 and the guide groove 400 is large, but since the radial dimension of the guide protrusion 300 is also large, the guide protrusion 300 is also easy to enter into the range corresponding to the guide groove 400, thereby correcting the deformation of the sub-compartment 10.

[0048] In some preferred embodiments, at least part of the guide protrusions 300 are located outside the part of the first end surface 100 corresponding to the support section 500. It can be understood that the support section 500 is a part of the peripheral wall of the sub-compartment 10, and the end surface corresponding to the peripheral wall is a part of the first end surface 100. The first end surface 100 corresponding to the support section 500 is not easy to deform due to the support of the compartment support structure 30, and this part can be provided with fewer guide protrusions 300, or no guide protrusions 300. However, on the first end surface 100 not corresponding to the support section 500, it is necessary to set the guide protrusion 300 to correct the deformation of the sub-compartment 10. The part of the sub-compartment 10 that is not in direct contact with the compartment support structure 30, that is, the peripheral wall of the sub-compartment 10 except the support section 500, is greatly affected by gravity and has a large deformation. Setting the guide protrusion 300 on the first end surface 100 corresponding to this part is conducive to correcting the deformation of the sub-compartment 10 and facilitating the assembly and docking of the sub-compartment 10.

[0049] refer to Fig.11 As shown, the first end face 100 may be provided with six guide protrusions 300, and the guide protrusions 300 may be evenly distributed along the circumference of the sub-compartment 10, or may be provided according to the matching relationship between the sub-compartment 10 and the compartment support structure 30. Exemplarily, the six guide protrusions 300 are symmetrically distributed, wherein two guide protrusions 300 are respectively located at the top and bottom of the first end face 100, and the remaining four guide protrusions 300 are respectively located at the left and right sides of the first end face 100. There is only one guide protrusion 300 corresponding to the support section 500, and five guide protrusions 300 are located outside the first end face 100 corresponding to the support section 500, thereby improving the correction effect on the deformation of the sub-compartment 10. Preferably, a coordinate axis is established with the axis center line of the sub-compartment 10, and the four guide protrusions 300 located at the left and right sides of the first end face 100 are respectively located on the angular bisector of each quadrant of the coordinate axis, which is more conducive to the assembly and connection of the two sub-compartments 10.

[0050] refer to Fig.12 As shown, the first end face 100 may be provided with four guide protrusions 300, and the four guide protrusions 300 are evenly distributed along the circumference of the sub-compartment 10. The four guide protrusions 300 can also have a good corrective effect on the deformation of the sub-compartment 10. At the same time, they have almost no effect or little effect on the structural strength of the sub-compartment 10.

[0051] After the two adjacent sub-compartments 10 are docked, the connecting member 20 and the locking member 40 are used to connect the two adjacent sub-compartments 10. Fig.10As shown, the guide protrusion 300 is provided with a first through hole 610 along its axial direction, and the guide groove 400 is provided with a second through hole 620 penetrating the bottom thereof, the first through hole 610 and the second through hole 620 are coaxially arranged, and the connecting member 20 is sequentially penetrated through the first through hole 610 and the second through hole 620 to fix the relative positions of the two sub-compartments 10. The second through hole 620 penetrating the bottom of the guide groove 400 means that the guide groove 400 is arranged on the end face of the sub-compartment 10, and a part of the sub-compartment 10 corresponding to the bottom of the guide groove 400 is penetrated by the second through hole 620.

[0052] refer to Figure 2 and Figure 3 As shown, in order to facilitate the installation of the connecting member 20 and the locking member 40, in some embodiments, the peripheral wall of the sub-compartment section 10 is provided with an inwardly recessed installation groove, and the installation groove is connected to the corresponding first through hole 610 or the second through hole 620. The connecting member 20 can be directly moved from the outside to the installation groove, and then inserted into the first through hole 610 and the second through hole 620 in sequence. Subsequently, the shielding plate 910 can be directly set to cover the notch of the installation groove, refer to Figure 1 As shown, the outer tube of the sub-compartment 10 is kept clean. The locking member 40 is also sleeved on the portion of the connector 20 passing through the second through hole 620 through the mounting groove. In other embodiments, a mounting groove may be provided inside the sub-compartment 10 to correspond to the first through hole 610 or the second through hole 620, so as to facilitate the assembly of the connector 20.

[0053] When the connector 20 is inserted into the first through hole 610 and the second through hole 620, there is an assembly gap between the connector 20 and the inner wall of the first through hole 610 and the inner wall of the second through hole 620, and the position of the connector 20 in the first through hole 610 and the second through hole 620 is not uniquely determined. Fig.10 As shown, a positioning groove 611 is provided at the entrance end of the first through hole 610, and the axis of the positioning groove 611 overlaps with the axis of the guide protrusion 300. A positioning protrusion 21 is provided on the connecting member 20, and the positioning protrusion 21 can be inserted into the positioning groove 611, and the axis of the positioning groove 611 overlaps with the axis of the positioning protrusion 21, thereby fixing the position of the connecting member 20 in the first through hole 610 and the second through hole 620, so that the axis of the connecting member 20 overlaps with the first through hole 610 and the second through hole 620.

[0054] In the process of assembling the connector 20, refer to Figure 8 and Fig. 9As shown, during the process of the connecting member 20 passing through the first through hole 610 and the second through hole 620, the positioning protrusion 21 of the connecting member 20 can also gradually move toward the positioning groove 611 of the first through hole 610. Part of the connecting member 20 passes through the second through hole 620, and the locking member 40 is sleeved outside the part of the connecting member 20. By rotating the locking member 40, the positioning protrusion 21 and the positioning groove 611 are driven to gradually approach each other until the outer wall of the positioning protrusion 21 gradually contacts the inner wall of the positioning groove 611, and the outer wall and the inner wall are in contact and fit. Moreover, as the inner wall and the outer wall gradually contact each other, the relative position of the positioning protrusion 21 and the positioning groove 611 can also be adjusted, and the axial position of the positioning protrusion 21 can be adjusted so that the axis of the positioning protrusion 21 and the axis of the positioning groove 611 gradually approach each other until they overlap.

[0055] The position of the connector 20 is determined by the cooperation between the positioning protrusion 21 and the positioning groove 611, so that the connector 20 is in a preset installation position and stably connected between the guide protrusion 300 and the guide groove 400. The connector 20 generally selects a screw bolt structure, and the locking member 40 generally selects a nut structure. After the screw passes through the first through hole 610 and the second through hole 620, the nut is locked on the screw to complete the fixation. In some specific embodiments, the circumferential side wall of the positioning protrusion 21 can be set to a conical surface structure.

[0056] In some preferred embodiments, a third guide surface 420 may be provided at the inlet end of the guide groove 400. Figure 4 and Figure 5 As shown, the third guide surface 420 is arranged around the axis of the guide groove 400, and the radial dimension corresponding to the third guide surface 420 gradually decreases along the direction in which the guide protrusion 300 is inserted into the guide groove 400, until the inner diameter of the third guide surface 420 is equal to the inner diameter of the inlet end of the second guide surface 410. The third guide surface 420 expands the inlet range of the guide groove 400, and the guide protrusion 300 is more likely to enter the range of the guide groove 400, cooperate with the guide groove 400, correct the deformation of the sub-compartment 10, and can correspondingly improve the docking efficiency and accuracy of the two sub-compartments 10.

[0057] The two sub-compartments 10 are also connected by a plurality of bolt connectors. A plurality of threaded holes are provided on the first end face 100 and the second end face 200 of the sub-compartment 10. The bolt connectors pass through the threaded holes to connect the two adjacent sub-compartments 10. The arrangement positions of the threaded holes can be referred to in Figure 5 and Figure 7 As shown, in other figures, in order to more clearly show the structure of the sub-compartment 10, the threaded holes are not drawn.

[0058] The sub-tank segment 10 generally includes a support frame 700 and a protective layer 900. The protective layer 900 covers the support frame 700 along the circumference of the support frame 700. Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 In actual use, the protective layer 900 is generally a metal skin, and the support frame 700 is generally called a middle frame. The support frame 700 plays a major supporting role.

[0059] In some embodiments of the present application, reference Figure 8 and Fig.13 As shown, the sub-compartment 10 further includes a first mounting frame 800, which is directly mounted on the inner side of the support frame 700 and is used to provide a mounting platform for various instruments and equipment. The support frame 700 is generally annular, and the space formed inside it is the inner space of the sub-compartment 10. The first mounting frame 800 is mounted on the inner side of the support frame 700, so that the first mounting frame 800 can be used to mount various instruments and equipment.

[0060] Exemplarily, the first mounting frame 800 includes two sub-frames 810 parallel to each other and a plurality of mounting plates 820. The sub-frame 810 is fixed to the support frame 700, and the mounting plate 820 is detachably connected between the two bracket bodies. The operator can adjust the position of the mounting plate 820 according to the size and installation position of the equipment to be installed. The mounting plate 820 can be provided with a variety of specifications, which is more convenient for the operator to adjust flexibly. In a specific implementation, a plurality of threaded holes can be provided on the sub-frame 810 and the mounting plate 820, and the mounting plate 820 is detachably connected to the sub-frame 810 through a connection structure such as screws.

[0061] In addition, it should be noted that in order to facilitate the assembly of the overall structure of the sub-compartment 10, a plurality of threaded holes are also provided on the support frame 700. In order to more clearly show the structure of the first mounting frame 800 and the support frame 700, the threaded holes are not drawn in the accompanying drawings.

[0062] Further preferably, two first mounting frames 800 are provided, and the two first mounting frames 800 are vertically arranged inside the support frame 700. The two first mounting frames 800 are in contact with each other, and the first mounting frame 800 located below the gravity direction can support the first mounting frame 800 located above the gravity direction. The two first mounting frames 800 can be connected by using structural members such as screws, or they can be unconnected.

[0063] In some preferred embodiments, reference Fig.13As shown, expansion parts 811 are provided at both ends of the sub-frame 810, and the expansion parts 811 are expanded in the width direction of the sub-frame 810 to increase the end size of the sub-frame 810. The expansion parts 811 are used to be fixedly connected with the support frame 700. Since the expansion parts 811 are large in size, the contact area with the support frame 700 is large, and the connection stability is higher. Further, threaded holes can be provided at the end surface position of the expansion part 811, and the connecting parts 20 such as bolts and screws can directly pass through the mounting holes on the support frame 700 along the radial direction of the support frame 700 and be inserted into the threaded holes of the expansion parts 811 to complete the fixing of the expansion parts 811. At the same time, before the bolts and screws pass through the mounting holes on the support frame 700, they can first pass through the protective layer 900. In this way, the protective layer 900 can be fixed to the support frame 700 while fixing the sub-frame 810 and the support frame 700, thereby improving the assembly efficiency of the sub-compartment 10. In other embodiments, the protective layer 900, the support frame 700 and the expansion portion 811 may be fixed simultaneously by riveting.

[0064] In some embodiments provided in the present application, the support frame 700 includes a plurality of annular support frames 710 and a second mounting frame 720, wherein the plurality of annular support frames 710 are arranged along the axial direction of the support frame 700. Figure 8 As shown, a vertical fixing member is also provided between two adjacent annular support frames 710. In order to more clearly observe the structure of the annular support frame 710, the vertical fixing member is not drawn in the figure, and the annular support frame 710 has a variety of structures. Figure 8 The cross section of the annular support frame 710 is a T-shaped structure, referring to Fig.14 As shown, the annular support frame 710 includes a rib plate 712 and a wing plate 711. The wing plate 711 is located outside the rib plate 712 to cover the protective layer 900. The two ends of the second mounting frame 720 are respectively fixed to the rib plates 712 of the two adjacent annular support frames 710. Fig.15 As shown, the second mounting frame 720 is fixed to the rib plate 712, and will not affect the coverage of the protective layer 900. The second mounting frame 720 connects two adjacent annular support frames 710, which can improve the structural stability and strength of the two adjacent annular support frames 710. The second mounting frame 720 is used to provide a mounting platform for the equipment, and the equipment is directly mounted on the second mounting frame 720. The equipment can be a gas tank or other equipment.

[0065] In the axial direction of the support frame 700, the rib plate 712 fixed to the second mounting frame 720 is located between the two ends of the second mounting frame 720, and the second mounting frame 720 is used to install the equipment. The two ends of the second mounting frame 720 are located outside the rib plates 712 of the two adjacent annular support frames 710. The two ends of the second mounting frame 720 are bent so that they can be directly connected and fixed to the rib plates 712 of the annular support frame 710. In addition, the two ends of the second mounting frame 720 are located outside the rib plates 712, and are fixed to the rib plates 712 more stably.

[0066] refer to Fig.15 As shown, the support frame 700 also includes a plurality of third mounting frames 730, which are fixed between two adjacent annular support frames 710, and are used to fix signal lines and / or pipelines. The signal lines are used to transmit signals, and the pipelines are connected to containers such as gas tanks to transport liquid / gas media. The third mounting frames 730 can also be used to fix wire clamps, which are used to bind multiple signal lines and / or pipelines, so that the interior of the sub-compartment 10 remains tidy.

[0067] The third mounting frame 730 is provided with a plurality of fixing through holes, and the signal line and / or pipeline can be fixed on the third mounting frame 730 by the cooperation of the connecting piece 20 and the fixing through hole. The third mounting frame 730 and the annular support frame 710 can also be fixed by passing the connecting piece 20 such as bolts and screws through the fixing through hole. At the same time, the fixing through hole on the third mounting frame 730 can also be used to fix the corresponding device to the third mounting frame 730. The wire clamp can be fixed to the third mounting frame 730 by the fixing through hole in cooperation with other fixing members. For example, the wire clamp can be fixed to the third mounting frame 730 by the fixing through hole in cooperation with the fixing through hole by structures such as bolts and screws.

[0068] In some embodiments, along the circumference of the support frame 700, a fourth mounting frame 740 is fixed between two adjacent third mounting frames 730. Fig.15 As shown, a wiring device can be fixed on the fourth mounting frame 740, and the wiring device is used to connect with the signal line and / or pipeline. The signal lines and / or pipelines etc. passed through the third mounting frames 730 on both sides of the fourth mounting frame 740 can be connected with the wiring device, so as to improve the convenience of wiring the signal lines and / or pipelines etc. At the same time, since the wiring device is located between the two third mounting frames 730, during the wiring process of the signal lines and / or pipelines, their extension direction will be changed to connect with the wiring device, which is convenient for the operator to connect, and also avoids the pipelines and / or signal lines being directly gathered on the third mounting frames 730, which affects the operation and the appearance.
