[0022] Exemplary embodiments of the present disclosure will be described herein below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0023] Embodiment of the inner support plate:

[0024] Referring to Figures 1 to 4 , the preferred structure of the inner support plate in the embodiment is shown in the figure. As shown in the figure, the inner support plate comprises a plate body 1, a plug-in mechanism and a guide mechanism 3. Among them, the plate body 1 is arc-shaped, and the plate body 1 has a predetermined elasticity, which can be determined according to actual conditions, and the present embodiment does not make any limitation on this.

[0025] Preferably, the plate body 1 comprises a plurality of arc-shaped bodies 12. Among them, each arc-shaped body 12 is sequentially stacked and connected together to form the plate body 1. Each arc-shaped body 12 has a predetermined elasticity.

[0026] More preferably, the material of each arc-shaped body 12 is stainless steel spring material, and each arc-shaped body 12 can be a stainless steel spring plate.

[0027] In practice, the outermost arc-shaped body 12 can have a thickness of 1 mm, and the thickness of the remaining arc-shaped bodies 12 can be 2 mm.

[0028] The plate 1 is detachably connected to the drive device 4. Specifically, a recessed portion 11 is provided in the middle of the plate 1, extending into the arc shape, and the recessed portion 11 is detachably connected to the drive device 4. More specifically, the recessed portion 11 extends from the outside of the arc shape into the inside. The recessed portion 11 and the drive device 4 can be connected by bolts 5 to fix the recessed portion 11 relative to the drive device 4.

[0029] The insertion mechanism is located at the first end of plate 1. Figure 2 The left end shown), the second end of plate 1 ( Figure 2 The right end shown is used for insertion into the insertion mechanism of adjacent inner support plates. Specifically, when two adjacent inner support plates are connected, the second end of the plate body 1 of one inner support plate is inserted into the insertion structure of the first end of the plate body 1 of the other inner support plate. The connection between the two adjacent inner support plates is achieved through the insertion of the second end of the plate body 1 into the insertion mechanism.

[0030] The insertion mechanism has a preset insertion space, which refers to the size of the insertion space. This preset space can be determined according to actual conditions, and this embodiment does not impose any restrictions on it. This allows the second end of the plate 1 of adjacent inner support plates to have a certain amount of movement space within the insertion space. When the driving device 4 drives the plate 1 to move, the end of the plate 1 is restricted by the insertion space, allowing adjustment of the bending degree of the plate 1. Furthermore, the first end of one of the two adjacent inner support plates overlaps with the second end of the other plate 1 within the insertion space. When the diameter of the cylindrical section is large, the overlap area is short; when the diameter of the cylindrical section is small, the overlap area is long.

[0031] The guide mechanism 3 is provided in the insertion mechanism. The guide mechanism 3 is used to guide the second end of the plate 1 in the adjacent inner support plate so that the second end of the plate 1 is inserted into the insertion mechanism.

[0032] In practice, the outer arc of plate 1 contacts the inner wall of the first cylindrical section, and the driving device 4 drives plate 1 to move to adjust the degree of curvature of plate 1 so that the arc of plate 1 is in close contact with the inner wall of the first cylindrical section. Then, the second cylindrical section is aligned and connected with the first cylindrical section.

[0033] It can be seen that in the embodiment, the second end of the plate body 1 is inserted into the insertion mechanism of the adjacent inner support plate. When the plurality of inner support plates are connected in sequence, the two end portions of the plate body 1 are limited by the plate body 1 of the adjacent inner support plate. The driving device 4 drives the plate body 1 to move, so as to adjust the bending degree of the plate body 1, so that the plate body 1 is tightly attached to the cylinder segment, thereby facilitating the installation of the two cylinder segments. The guide mechanism 3 can guide the second end of the plate body 1 in the adjacent inner support plate, so as to ensure that the plate body 1 in the adjacent inner support plate is stably inserted into the insertion mechanism. In addition, the driving device 4 is detachably connected with the plate body 1, and the adjacent two inner support plates are inserted, which can be repeatedly used, improves the utilization rate, reduces the tooling, reduces the cost, and solves the problem that one inner support device is easily caused by too many toolings in the prior art.

[0034] Referring to Figures 1 to 4 , the insertion mechanism comprises a plurality of insertion assemblies 2. Each insertion assembly 2 is arranged at the first end of the plate body 1 at intervals. Specifically, each insertion assembly 2 is arranged at intervals along the length direction of the plate body 1 (the arc direction shown). Figure 2

[0035] Each insertion assembly 2 can comprise a limiting structure 21 and two baffle plates 22. The two baffle plates 22 are arranged side by side and have a certain distance therebetween. The first end of each baffle plate 22 is connected with the plate body 1, and the two baffle plates 22 are arranged on both sides of the plate body 1 in the width direction.

[0036] The limiting structure 21 is arranged at the second end of the two baffle plates 22, and the limiting structure 21 is arranged opposite to the plate body 1, and has a certain distance therebetween. The limiting structure 21, the plate body 1 and the two baffle plates 22 surround the insertion space, and the insertion space accommodates the second end of the plate body 1 in the adjacent inner support plate.

[0037] It can be seen that in the embodiment, the structure of the insertion mechanism is simple and easy to implement.

[0038] Referring to Figures 1 to 4 , the guide mechanism 3 comprises at least one guide plate 31. Each guide plate 31 is arc-shaped. The arc center of the guide plate 31 and the arc center of the plate body 1 are arranged on the same side, and the guide plate 31 is arranged on the limiting structure 21 of the insertion assembly 2. In this way, the arrangement of the guide plate 31 can guide the second end of the plate body 1, so as to ensure that the plate body 1 is accurately inserted into the insertion mechanism.

[0039] ​In specific implementation, the number of the guide plates 31 can be the same as the number of the limiting structures 21, and each guide plate 31 corresponds to each limiting structure 21, and each guide plate 31 is arranged on the corresponding limiting structure 21. Of course, the number of the guide plates 31 can be different from the number of the limiting structures 21, and the number of the guide plates 31 is less than the number of the limiting structures 21, and each guide plate 31 is arranged on one limiting structure 21, and each guide plate 31 can be arranged at intervals or adjacent to each other.

[0040] The limiting structure 21 can include a pressing plate 211, a ring 212, and a connecting piece 213. The ring 212 is in a U shape, and has two ends and a middle section connecting the two ends. The two ends of the ring 212 correspond to the two stop plates 22, and each end of the ring 212 is connected to the second end of the corresponding stop plate 22.

[0041] The pressing plate 211 is arranged in the insertion space, and the pressing plate 211 is arranged opposite to the middle section of the ring 212. The guide plate 31 is arranged between the middle section of the ring 212 and the pressing plate 211, and the ring 212, the guide plate 31, and the pressing plate 211 are connected together by the connecting piece 213. Specifically, the pressing plate 211 is arranged inside the ring 212, that is, two side walls of the pressing plate 211 are in contact with the two ends of the ring 212, and the guide plate 31 is arranged between the pressing plate 211 and the middle section of the ring 212.

[0042] Preferably, the middle section of the ring 212 and the guide plate 31 are both provided with through holes, and the pressing plate 211 is provided with a threaded hole. The connecting piece 213 is a bolt, which is sequentially arranged in the through holes of the ring 212 and the guide plate 31 and is screwed with the threaded hole of the pressing plate 211, so as to connect the ring 212, the guide plate 31, and the pressing plate 211 together.

[0043] Preferably, the two opposite side walls of the pressing plate 211 are provided with guide portions 214 outwardly protruding along the length direction of the plate body 1. Specifically, the pressing plate 211 is in a cuboid shape, two side walls of the pressing plate 211 are in contact with the two ends of the ring 212, the other two side walls of the pressing plate 211 are located in the length direction of the plate body 1, and the other two side walls of the pressing plate 211 are respectively provided with a guide portion 214 extending away from the pressing plate 211, so that there are two guide portions 214. Each guide portion 214 is in a right triangle shape in cross section, one right angle face of each guide portion 214 is connected to the side wall of the pressing plate 211, and the other right angle face of each guide portion 214 is parallel to the middle section of the ring 212. In the length direction of the plate body 1, the cross section shape of the pressing plate 211 and the two guide portions 214 is isosceles trapezoidal.

[0044] It can be seen that, in the embodiment, the guide mechanism 3 guides the second end of the plate body 1 of the adjacent inner support plate through the plurality of guide plates 31, ensuring that the second end of the plate body 1 of the adjacent inner support plate is stably inserted into the insertion space. The limiting structure 21 can limit the insertion space, thereby effectively limiting the second end of the plate body 1.

[0045] In summary, in the embodiment, the second end of the plate body 1 is inserted into the insertion mechanism of the adjacent inner support plate, and when a plurality of inner support plates are connected in sequence, both ends of the plate body 1 are limited by the plate body 1 of the adjacent inner support plate. The driving device 4 drives the plate body 1 to move, which can adjust the bending degree of the plate body 1, so that the plate body 1 is tightly attached to the cylinder segment, thereby facilitating the installation of the two cylinder segments. The guide mechanism 3 can guide the second end of the plate body 1 in the adjacent inner support plate, ensuring that the plate body 1 is stably inserted into the insertion mechanism. In addition, the driving device 4 is detachably connected with the plate body 1, and the adjacent two inner support plates are inserted, which can be reused, improving the utilization rate, reducing the tooling, and reducing the cost.

[0046] Inner support device embodiment:

[0047] The embodiment also provides an inner support device, which is described below with reference to Figure 5 The inner support device comprises a plurality of driving devices 4 and a plurality of any of the above-mentioned inner support plates. Each inner support plate is connected in sequence to form an annular structure 6, which is used to be placed inside the cylinder segment. Specifically, the second end of the plate body 1 in one of any two adjacent inner support plates is inserted into the insertion mechanism in the other inner support plate. In this way, each inner support plate is connected in sequence to form an annular structure 6. The arc-shaped outer part of the plate body 1 in each inner support plate is in contact with the inner wall of the cylinder segment. The specific implementation process of the inner support plate is described above and will not be repeated here.

[0048] Each driving device 4 corresponds to the plate body 1 in each inner support plate, and each driving device 4 is connected to the plate body 1 in the corresponding inner support plate. Each driving device 4 is used to drive the plate body 1 in the corresponding inner support plate to move, so as to adjust the bending degree of the inner support plate, and then make the arc-shaped plate body 1 tightly contact with the inner wall of the cylinder segment.

[0049] In specific implementation, each driving device 4 can be supported and fixed by a support device, and each driving device 4 is arranged in a circumferential manner. In addition, each driving device 4 and the support device are placed inside the annular structure 6. In the initial state, each driving device 4 is shortened to the minimum, thereby driving each plate body 1 to shrink towards the inside of the annular structure, and the cylinder segment is sleeved on the outside of the annular structure. Then, each driving device 4 drives each plate body 1 to move towards the outside of the annular structure until each plate body 1 is in contact with the cylinder segment. After the two cylinder segments are adjusted and aligned, they are spot welded.

[0050] In the implementation, the driving device 4 can be a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, a rolled thread screw, a spring plus a screw rod, etc., and the present embodiment does not make any limitation.

[0051] Since the inner support plate has the above effects, the inner support device with the inner support plate also has corresponding technical effects.
