[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0025] like Figure 1 As shown, the outer wall of the flame tube 100 has a plurality of overlap blocks 101, the inner wall of the guide bushing 200 has a plurality of support members 201, the flame tube 100 is installed in the guide bushing 200, and the plurality of overlap blocks 101 are overlapped on the plurality of support members 201 one by one to form an installation assembly. It can be understood that the flame tube 100 is overlapped on the support members 201 one by one through the plurality of overlap blocks 101, so that the guide bushing 200 supports the flame tube 100, so when the support members 201 of the guide bushing 200 are pulled, the flame tube 100 can be driven to move at the same time through the guide bushing 200.

[0026] This embodiment provides an assembly tool for a combustion chamber assembly, which is used to install the above-mentioned installation assembly on the combustion cylinder. Figures 1 to 4As shown, the assembly tool of the combustion assembly includes a frame 1, a drive assembly 2 and a connection assembly 3, wherein the frame 1 has an installation channel 12 for the installation assembly to enter and exit. The drive assembly 2 is arranged on the frame 1. The connection assembly 3 is located in the installation channel 12, and the connection assembly 3 has a first connection part and a second connection part, wherein the first connection part is connected to the drive assembly 2, and the second connection part is used to be connected to the support member 201, so that the drive assembly 2 drives the installation assembly to move along the installation channel 12 through the connection assembly 3.

[0027] Specifically, the shape of the frame 1 can match the shape of the mounting assembly, which is beneficial to reducing the volume. The specific structural composition of the frame 1 can be set according to actual needs and is not limited here.

[0028] When the installation assembly needs to be installed, the second connection part of the connection component 3 is moved out of the installation channel 12 through the driving component 2, and the connection component 3 is connected to the installation assembly. The driving component 2 then moves the installation assembly into the installation channel 12 through the connection component 3, and then the assembly tool and the installation assembly are moved to the installation position and positioned together through the external lifting equipment. Finally, the driving component 2 transports the installation tool into the combustion cylinder through the connection component 3 to complete the assembly of the installation assembly. When the installation assembly needs to be disassembled, the second connection part of the connection component 3 is moved out of the installation channel 12 through the driving component 2, and after the second connection component is connected to the installation assembly, the driving component moves the installation assembly out of the combustion cylinder through the connection component 3 to complete the disassembly of the installation assembly.

[0029] To summarize, when the assembly tool in this embodiment is used to install or disassemble the installation assembly, the driving component 2 drives the connecting component 3 to move, so that the connecting component 3 moves to the position connected with the installation assembly, and the second connecting portion of the connecting component 3 is hooked on the support member 201, so that when the connecting component 3 is driven by the driving component 2 to move along the installation channel 12, the installation assembly can be driven to move by the connecting component 3, and then the installation assembly can be installed or disassembled. This embodiment connects the structure of the installation assembly itself to the connecting component 3, which facilitates the connection between the connecting component 3 and the installation assembly, thereby facilitating the assembly and disassembly of the installation assembly.

[0030] In this embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, the connecting component 3 includes a fixing part 31 and a plurality of first hooks 32. The fixing part 31 forms a first connecting portion, and the fixing part 31 is detachably or rotatably connected to the driving component 2; the plurality of first hooks 32 form a second connecting portion, and the plurality of first hooks 32 are arranged at circumferential intervals along the fixing part 31 and correspond one-to-one to the plurality of support members 201.

[0031] For example, when the number of the overlapping blocks 101 outside the flame tube 100 and the number of the supporting members 201 inside the guide sleeve 200 are both three, the number of hooks is set to three, and the distribution pattern of the three hooks is consistent with the distribution pattern of the overlapping blocks 101 and the supporting members 201. The number of hooks is set according to the number of the overlapping blocks 101 outside the flame tube 100 and the number of the supporting members 201 inside the guide sleeve 200, and the number of hooks is not used to limit the present utility model.

[0032] Specifically, the fixing component 31 is detachably connected or rotatably connected to the driving component, which means that the fixing component 31 can be detachably connected to the driving assembly 2, and the fixing component 31 can also be rotatably connected to the driving assembly 2. Since the first hook 32 needs to be extended into the gap between the flame tube 100 and the guide bushing 200 and then the hook is hung on the support 201 of the guide bushing 200 when the first hook 32 is connected to the installation assembly, therefore, after the first hook 32 is extended into the annular gap between the flame tube 100 and the guide bushing 200, the hook needs to be rotated to hook the hook on the support 201. When the fixing component 31 is detachably connected to the driving assembly 2, when the first hook 32 is connected to the installation assembly, the fixing component 31 needs to be separated from the driving assembly 2, and after the first hook 32 is connected to the installation assembly, the fixing component 31 is connected to the driving assembly 2. Similarly, when it is necessary to separate the first hook 32 from the installation assembly, it is necessary to separate the fixing component 31 from the driving component 2, and then rotate the fixing component 31 so that multiple first hooks 32 can be separated from the installation assembly at the same time. When the fixing component 31 is rotationally connected to the driving component 2, the driving component 2 drives the connecting component 3 to move, so that multiple first hooks 32 extend into the annular gap between the flame tube 100 and the guide bushing 200, and then rotate the fixing component 31 to make the first hook 32 hang on the support 201, so as to achieve the connection between the connecting component 3 and the installation assembly. Similarly, when it is necessary to separate the connecting component 3 from the installation assembly, rotate the fixing component 31, and drive the multiple first hooks 32 to rotate through the fixing component 31, so that the first hook 32 and the support 201 are separated, and then drive the connecting component 3 away from the installation assembly through the driving component 2, so as to achieve the separation of the connecting component 3 from the installation assembly.

[0033] It is understandable that by providing the fixing component 31 and the driving assembly 2, it is possible to facilitate the connection between the connecting assembly 3 and the driving assembly 2. By providing the second connecting portion as the first hook 32, it is possible to facilitate the connection or separation of the connecting assembly 3 and the mounting assembly, which is beneficial to improving the installation or removal efficiency of the mounting assembly.

[0034] In this embodiment, if Figure 2 and Figure 3As shown, the fixing component 31 includes a fixing plate 311 and a mounting member 312 . The fixing plate 311 is connected to the driving assembly 2 ; the mounting member 312 is connected to the fixing plate 311 , and a plurality of first hooks 32 are disposed on the mounting member 312 .

[0035] Specifically, when the fixing plate 311 and the driving assembly 2 are detachably connected, a connection hole can be set on the fixing plate 311 and the driving assembly 2, and the fixing plate 311 and the driving assembly 2 are connected by bolts. The specific connection method of the bolt hole can be set according to actual needs and will not be described in detail here. When the fixing plate 311 and the driving assembly 2 are rotationally connected, a connecting shaft can be set on the driving plate, and the connecting shaft is rotationally connected to the driving assembly 2. The specific connection method of the connecting shaft can be adjusted by technicians in this field according to actual needs and will not be described in detail here.

[0036] In this embodiment, by setting a fixing plate 311 connected to the driving assembly 2, the connection between the fixing component 31 and the driving assembly 2 can be facilitated, and by setting a mounting member 312 connected to the first hook 32, the installation of the first hook 32 can be facilitated.

[0037] In this embodiment, the mounting member 312 includes a plurality of mounting rods, one end of each of which is connected to the fixing plate 311 , and a plurality of first hooks 32 are connected to the plurality of mounting rods one by one and are located at one end of the mounting rods away from the fixing plate 311 .

[0038] For example, multiple mounting rods can be arranged at intervals along the circumference of the fixing plate 311 and connected to the fixing plate 311, or multiple mounting rods can be connected to the middle plate together, and connected to the fixing plate 311 through the middle plate. The installation method of the mounting rods can be selected as needed and is not limited here.

[0039] It can be understood that the mounting member 312 includes a plurality of mounting rods, and gaps can be formed between the plurality of mounting rods. By forming gaps between the mounting rods, when the first hook 32 is connected to the mounting assembly, the connection between the first hook 32 and the support member 201 can be easily observed through the gap, which helps to ensure that the first hook 32 and the support member 201 are reliably connected.

[0040] In this embodiment, if Figure 2 As shown, the connecting assembly 3 further includes a second hook 33 , and the second hook 33 is disposed on the fixing plate 311 .

[0041] For example, the second hook 33 includes a hooking portion and a connecting portion. The hooking portion may be annular and the connecting portion may be a screw. The second hook 33 is threadedly connected to the fixing plate 311 through the connecting portion. The screw can be provided to facilitate the connection between the second hook 33 and the fixing plate 311. The annular hooking portion can be provided to facilitate the connection with other driving components 21 through the hooking portion.

[0042] It should be noted that, by providing the second hook 33, when the drive assembly 2 drives the installation assembly to lift through the connection assembly 3, the second hook 33 can be connected to other drive devices to provide external auxiliary lifting force, which can reduce the load of the drive assembly 2 and improve the lifting efficiency. For example, the drive device can be an electric hoist.

[0043] In this embodiment, if Figures 2 to 4 As shown, the connection assembly 3 further includes a first connection member 34 , which is disposed on the fixing component 31 , and is used to connect the fixing component 31 to the flange of the guide bushing 200 .

[0044] Specifically, a threaded hole is provided on the flange of the guide bushing 200, and the first connecting member 34 can be a bolt. The first connecting member 34 is threadedly connected to the guide bushing 200. The structure of the guide bushing 200 itself is utilized to connect the connecting component 3 to the guide bushing 200, which can simplify the connection structure between the connecting component 3 and the guide bushing 200 and facilitate operation.

[0045] It can be understood that after the second connecting component is connected to the installation assembly, it is then connected to the installation assembly through the first connecting member 34, so that the connection reliability between the connecting component 3 and the installation assembly can be improved.

[0046] In this embodiment, if Figure 2 and Figure 3 As shown, the driving assembly 2 includes a driving member 21, a screw rod 22 and a connecting seat 23. The driving member 21 is arranged on the frame 1; the screw rod 22 is rotatably arranged on the frame 1 and is arranged along the extension direction of the installation channel 12. The screw rod 22 is connected to the driving member 21, and the connecting seat 23 is threadedly connected to the outside of the screw rod 22. The connecting assembly 3 is connected to the connecting seat 23.

[0047] For example, the driving member 21 includes a motor, which is connected to the screw rod 22 through a transmission component to drive the screw rod 22 to rotate. The specific structure of the transmission component can be set according to actual installation requirements and is not limited here.

[0048] Since the flame tube 100 is provided with a hula seal ring, a large external force is required to force the hula seal ring of the flame tube 100 through the transition section of the combustion cylinder. In this embodiment, the screw rod 22 is driven to rotate by the driving member 21, and the screw rod 22 converts the rotational motion into the axial movement of the connecting seat 23 along the screw rod 22, so that the thrust can be transmitted through the connecting seat 23 to drive the connecting assembly 3 to move along the axial direction of the screw rod 22, and then the connecting assembly 3 drives the installation assembly to move along the axial direction of the screw rod 22, which can facilitate the flame tube 100 to be pressed into the transition section or pulled out from the transition section, which is conducive to improving the installation or disassembly efficiency.

[0049] In this embodiment, two screw rods 22 are provided, and a connecting seat 23 is provided on each of the two screw rods 22. The driving component 2 also includes a connecting beam 24, and the two ends of the connecting beam 24 are connected to the connecting seats 23 on the two screw rods one by one. The connecting component 3 is connected to the connecting beam 24.

[0050] Specifically, the connecting assembly 3 is connected to the middle of the cross beam 24 so that the cross beam 24 is subjected to balanced force.

[0051] It is understandable that by providing two screw rods 22 , gravity is evenly applied to the two screw rods 22 through the cross beam 24 , which is beneficial to improving the overall stability and reducing the distortion or wear of the screw rods 22 due to uneven force.

[0052] In this embodiment, Figure 2 and Figure 3 As shown, in the assembly direction, a flange 11 is provided at the end of the frame 1 , and a positioning hole 111 is provided on the flange 11 .

[0053] It should be noted that when the installation assembly needs to be installed on the combustion cylinder, the assembly tooling of the combustion chamber assembly connected to the installation assembly is moved to the installation position through external lifting equipment, so that the positioning hole 111 on the flange 11 corresponds to the hole position on the combustion cylinder, and the frame 1 is positioned through the positioning hole 111, so that the installation assembly can be positioned through the frame 1, which is conducive to accurate installation of the installation assembly and convenient positioning, which is conducive to improving the installation efficiency of the installation assembly.

[0054] In this embodiment, the cross section of the installation channel 12 is circular.

[0055] It can be understood that setting the cross-section of the installation channel to a circle so that the shape of the installation channel matches the shape of the installation assembly can save space in the installation channel to the maximum extent, which is beneficial to reducing the volume of the frame 1, thereby helping to reduce the risk of collision of the frame 1 when moving.
