Description

Technical Field:

[0001] The present invention relates to a winding mold, and more particularly to a winding mold for a reactor. Background Art:

[0002] During the manufacturing process of reactors, inconsistent manufacturing quality will directly lead to unstable subsequent use performance. Due to reasons such as unqualified production quality, frequent failures, damage, and even burning accidents of air-core reactors are common. Especially the burning problem during operation has seriously affected the normal use performance of dry-type air-core reactors. Currently, most production modes of reactors are to produce according to the specific requirements of orders, that is, to manufacture reactors according to the required structural forms. Under such production requirements, different-sized molds need to be matched, and the inner diameters and widths of the corresponding molds often change. Currently, the means used for the molds is to fasten rectangular tubes with bolts on the two end circular surfaces. Since the reactor is large in size, the corresponding bolts are numerous, and the process of disassembling and assembling one by one is very troublesome. When demolding this kind of mold, the operation is very difficult. After removing the bolts, it is necessary to knock the rectangular tube out from one side, which is time-consuming and laborious. A large amount of time and labor are consumed in this link. Once the order requires other changes in diameter, the mold needs to be replaced. In order to ensure the accuracy of manufacturing reactors, it is impossible to use the same mold for radial adjustment, and it is difficult to effectively and stably achieve both manufacturing accuracy and adjustment flexibility. Currently, the compromise operation is to use the form of adding gaskets when the diameter changes slightly to expand the radial size of the mold. As a result, the distance between the rectangular tubes at the outer circumference of the fit becomes larger, affecting the roundness of the mold and thus affecting the product quality. Summary of the Invention:

[0003] To solve the problems mentioned in the above background art, the purpose of the present invention is to provide a winding mold for a reactor.

[0004] A winding mold for a reactor includes a circumferential support assembly and two end-face type support frames. The two end-face type support frames are arranged vertically and side by side. Each end-face type support frame includes a central hub, a plurality of adjusting rods, and a plurality of support seats. The plurality of adjusting rods are arranged around the central hub. One end of each adjusting rod is connected to the central hub, and a support seat is correspondingly arranged at the other end of each adjusting rod. The outer end face of the support seat is an arc surface, and adjacent support seats overlap each other. The outer end faces of the plurality of support seats form an annular support end. The circumferential support assembly includes a plurality of support tubes. The plurality of support tubes are arranged along the circumferential direction of the annular support end between the two annular support ends. There is a gap between adjacent support tubes, and the end of each support tube is tightly attached to the outer wall of the annular support end close to the end.

[0005] As a preferred solution: Two end-face type support frames are provided with two limit frames in cooperation. The limit frame includes a shaft sleeve and several support plates. The shaft sleeve is sleeved on the connecting shaft, and several support plates are arranged on the outer wall of the shaft sleeve. One end of each support plate is arranged on the shaft sleeve, and the other end of each support plate passes through the gap between two adjacent support tubes and is arranged outside the multiple support tubes.

[0006] As a preferred solution: The central hub includes a central shaft sleeve and multiple bottom connecting tubes. Multiple bottom connecting tubes are arranged on the outer circumferential surface of the central shaft sleeve. The length direction of the bottom connecting tube is the same as the radial direction of the central shaft sleeve. One end of the bottom connecting tube is connected to the central shaft sleeve, and a first internal thread is machined inside the other end of the bottom connecting tube. The other end of the bottom connecting tube is detachably connected to one end of the adjusting rod.

[0007] As a preferred solution: The other end of the adjusting rod is detachably connected to its corresponding support seat. Each support seat includes a top connecting tube, an intermediate connecting plate and a variable diameter seat body. A second internal thread matching the adjusting rod is machined at one end of the top connecting tube. The other end of the top connecting tube is arranged on the intermediate connecting plate. The intermediate connecting plate is detachably connected to the variable diameter seat body. The outer end face of the variable diameter seat body is an arc surface.

[0008] As a preferred solution: The adjusting rod includes an intermediate connecting rod and an adjusting handle. The adjusting handle is arranged on the intermediate connecting rod. The two ends of the intermediate connecting rod are respectively an upper adjusting end and a lower adjusting end. A first external thread matching the first internal thread is machined on the outer wall of the lower adjusting end, and a second external thread matching the second internal thread is machined on the outer wall of the upper adjusting end. The rotation directions of the first external thread and the second external thread are opposite.

[0009] As a preferred solution: The two ends of the variable diameter seat body are respectively lapping ends. The lapping length of the two adjacent lapping ends of two adjacent variable diameter seat bodies is the maximum circumferential adjustment distance between two adjacent variable diameter seat bodies.

[0010] As a preferred solution: The multiple variable diameter seat bodies include multiple first seat bodies and multiple second seat bodies. The multiple first seat bodies and the multiple second seat bodies are arranged alternately. Upper grooves are machined on the top surfaces of the two lapping ends of each first seat body, and positioning holes are machined at the bottoms of the upper grooves. Lower grooves are machined on the bottom surfaces of the two lapping ends of each second seat body. The first seat body is lapped with the lower groove of the second seat body through the upper groove.

[0011] As a preferred solution: Placement grooves corresponding to the support tubes one by one are machined on the arc surface of the variable diameter seat body.

[0012] As a preferred solution: The support tubes are square tubes. A fastening rope is threaded through the multiple support tubes, and a fastening device is provided in cooperation with the fastening rope.

[0013] As a preferred solution: when the maximum circumferential adjustment distance between two adjacent reduced-diameter seat bodies matches the width of the support pipe, a special-shaped pipe is provided between the two overlapping ends of the two adjacent reduced-diameter seat bodies. The shape of the special-shaped pipe is the same as that of the support pipe. A notch matching the fastening rope is machined along the length direction of the end of the special-shaped pipe. A limiting block is provided on the outer end face of the special-shaped pipe facing the overlapping end of the reduced-diameter seat body. The limiting block and the positioning hole on the overlapping end are detachably connected through a positioning pin shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] First, the structure of the present invention is reasonable. The circumferential support assembly and the two end-face type support frames are combined to be applicable to reactors with different basic diameters, achieving the technical effect that as the basic diameter increases, the adjustment increment correspondingly increases. The self-adjustment process of the mold is simple, simplifying the operation difficulty, being convenient and fast to fix, and quickly and reliably demolding, saving time and reducing the labor amount, so that the manufacturing accuracy and adjustment flexibility of the reactor can be stably obtained at the same time.

[0016] Second, the present invention is particularly applicable to the production and manufacturing of reactors with a basic diameter of more than 1000 mm and an optimal diameter adjustment amount within the range of 360 / π mm.

[0017] Third, the structure design of the end-face type support frame in the present invention is ingenious, and it can achieve its own diameter-changing effect. The basic diameter can be set to 1000 mm or 2000 mm, increasing in increments of 120 mm. The diameter-changing range is that the optimal diameter adjustment amount is within the range of 360 / π mm, which can meet the radial dimension requirements of most reactors currently in use and has a certain universality. At the same time, the diameter-changing effect achieved by the cooperation between the central hub, multiple adjusting rods and multiple support seats is stable, and it can cooperate with the circumferential support assembly to ensure the smoothness of the outer circumferential surface after diameter change, providing a favorable basis for producing high-quality and unified products.

[0018] Fourth, the overlapping connection relationship between two adjacent support seats can achieve the support effect after fine adjustment of the two adjacent support seats, and the adjustment process is simple and easy to operate.

[0019] Fifth, the present invention directly passes the fastening rope through the round hole of the support pipe and winds it around the outer circular surface formed by the support pipe for one or two circles to lock and fix, avoiding the cumbersome operation of bolt disassembly. The whole adjustment process does not require disassembly of parts, and only needs to be changed through the self-adjustment of the overall structure, which is beneficial to saving the workload of manual disassembly and assembly.

[0020] Sixth, the present invention can be realized by corresponding transformation of the existing reactor mold, which is beneficial to the continued use of the existing reactor mold after transformation, saving energy and reducing emissions.

[0021] 7. The connecting shaft is changed from a round shaft with a key connection to a square shaft with screw positioning, which is convenient and fast to connect, can transmit a greater load, and works more stably. Brief Description of the Drawings:

Specific implementation manners:

[0040] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be described below through specific embodiments shown in the drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present invention.

[0041] Here, it should also be noted that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the drawings, while other details less related to the present invention are omitted.

[0042] Specific implementation manner one: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16As shown in the figure, the present specific implementation adopts the following technical solutions: This implementation includes a circumferential support assembly and two end-face type support frames 2. The two end-face type support frames 2 are arranged vertically and side by side. Each end-face type support frame 2 includes a central hub 2-1, a plurality of adjusting rods 2-2, and a plurality of support seats 2-3. The plurality of adjusting rods 2-2 are arranged around the central hub 2-1. One end of each adjusting rod 2-2 is connected to the central hub 2-1, and a support seat 2-3 is correspondingly arranged at the other end of each adjusting rod 2-2. The outer end face of the support seat 2-3 is an arc surface, and the adjacent two support seats 2-3 are lap-connected. The outer end faces of the plurality of support seats 2-3 form an annular support end. The circumferential support assembly includes a plurality of support tubes 1. The plurality of support tubes 1 are arranged between the two annular support ends along the circumferential direction of the annular support end. There is a gap between adjacent two support tubes 1, and the end of each support tube 1 is tightly attached to the outer wall of the annular support end close to this end.

[0043] Specific implementation method two: This implementation method is a further limitation of the first implementation method. The two central hubs 2-1 are coaxially connected by a connecting shaft 3. The connecting shaft 3 is a square shaft body or a circular shaft body. The connecting shaft 3 can ensure the coaxial connection of the two central hubs 2-1, ensuring the stability of the overall structure and the accuracy of positioning.

[0044] Specific implementation method three: This implementation method is a further limitation of the first or second implementation method. Two limiting frames 4 are arranged in cooperation between the two end-face type support frames 2. The limiting frame 4 includes a shaft sleeve 4-1 and several support plates 4-2. The shaft sleeve 4-1 is sleeved on the connecting shaft 3, and several support plates 4-2 are arranged on the outer wall of the shaft sleeve 4-1. One end of each support plate 4-2 is arranged on the shaft sleeve 4-1, and the other end of each support plate 4-2 passes through the gap between adjacent two support tubes 1 and is arranged outside the plurality of support tubes 1.

[0045] In this implementation method, the support plate 4-2 is a strip-shaped plate body, and the shaft sleeve 4-1 and several support plates 4-2 are integrally formed structures. The thickness direction of the support plate 4-2 is the same as the axial direction of the shaft sleeve 4-1.

[0046] Furthermore, half of the number of the several support plates 4-2 are respectively provided with limiting lugs 13 for assembling with the reactor. The limiting lugs 13 are arranged outside the plurality of support tubes 1. The limiting lugs 13 are connecting members for installing the reactor, enhancing the connection relationship between the present invention and the reactor and making their connection stable.

[0047] Embodiment 4: This embodiment is a further limitation of Embodiment 1, 2 or 3. The central hub 2-1 includes a central shaft sleeve 2-1-1 and a plurality of bottom connecting pipes 2-1-2. A plurality of bottom connecting pipes 2-1-2 are arranged on the outer circumferential surface of the central shaft sleeve 2-1-1. The length direction of the bottom connecting pipe 2-1-2 is the same as the radial direction of the central shaft sleeve 2-1-1. One end of the bottom connecting pipe 2-1-2 is connected to the central shaft sleeve 2-1-1. The other end of the bottom connecting pipe 2-1-2 is internally processed with a first internal thread, and the other end of the bottom connecting pipe 2-1-2 is connected to the adjusting rod 2-2.

[0048] Further, when the connecting shaft 3 is a circular shaft body, the outer diameter of the connecting shaft 3 is not less than half of the outer diameter of the central shaft sleeve 2-1-1. Such a dimensional relationship can ensure that the overall structural support strength remains unchanged and does not deform.

[0049] Further, a first reinforcing plate is provided between two adjacent bottom connecting pipes 2-1-2. The shape of the first reinforcing plate is fan-shaped, which is used to strengthen the relative position between each bottom connecting pipe 2-1-2 and the central shaft sleeve 2-1-1 to be permanently stable, thereby ensuring the accuracy of manufacturing the reactor of the present invention.

[0050] Embodiment 5: This embodiment is a further limitation of Embodiment 1, 2, 3 or 4. The other end of the adjusting rod 2-2 is detachably connected to the support seat 2-3. The support seat 2-3 includes a top connecting pipe 2-3-1, an intermediate connecting plate 2-3-2 and a reduced-diameter seat body 2-3-3. One end of the top connecting pipe 2-3-1 is processed with a second internal thread that matches the adjusting rod 2-2. The other end of the top connecting pipe 2-3-1 is detachably connected to the reduced-diameter seat body 2-3-3 through the intermediate connecting plate 2-3-2. The outer end face of the reduced-diameter seat body 2-3-3 is an arc surface.

[0051] In this embodiment, two second reinforcing plates are respectively provided between the two sides of the top connecting pipe 2-3-1 and the intermediate connecting plate 2-3-2, which are used to increase the support strength of the support seat 2-3.

[0052] In this embodiment, the reduced-diameter seat body 2-3-3 has the effect of expanding or reducing the diameter of the end-face support frame 2, enhancing the versatility during the use of the present invention, being applicable to the assembly of reactors with different diameters, avoiding the complex operations caused by the diameter change of the current assembly mold, and the problem that the change ranges of each ring segment are difficult to unify.

[0053] One end of the intermediate connecting plate 2-3-2 facing the reduced-diameter seat body 2-3-3 is matched with the inner wall of the reduced-diameter seat body 2-3-3.

[0054] Further, one end of the intermediate connecting plate 2-3-2 facing the diameter-changing seat body 2-3-3 is matched with the inner wall of the diameter-changing seat body 2-3-3 through a plurality of connecting screws on the diameter-changing seat body 2-3-3, and the preferred number of connecting screws is two.

[0055] Specific Embodiment Six: This embodiment is a further limitation of Embodiment One, Two, Three, Four or Five. The adjusting rod 2-2 includes an intermediate connecting rod and an adjusting handle 2-2-3. The adjusting handle 2-2-3 is arranged on the intermediate connecting rod. The two ends of the intermediate connecting rod are respectively an upper adjusting end 2-2-1 and a lower adjusting end 2-2-2. An external thread matching the first internal thread is machined on the outer wall of the lower adjusting end 2-2-2, and an external thread matching the second internal thread is machined on the outer wall of the upper adjusting end 2-2-1. The rotation directions of the first external thread and the second external thread are opposite.

[0056] In this embodiment, the rotation directions of the first external thread and the second external thread are opposite to ensure that when the adjusting handle 2-2-3 is screwed, the adjusting handle 2-2-3 drives the intermediate connecting rod to rotate, and synchronously realizes the adjustment process of the upper adjusting end 2-2-1 and the top connecting pipe 2-3-1 and the adjustment process of the lower adjusting end 2-2-2 and the bottom connecting pipe 2-1-2. The adjustment process is synchronous and unified, and can realize the adjustment of increasing or decreasing the radial dimension of the mold at the same time, providing a stable change basis for the diameter-changing adjustment process of the overall structure.

[0057] Further, for anti-loosening load-bearing, the first internal thread, the first external thread, the second internal thread and the second external thread all adopt square thread.

[0058] Further, the preferred structure of the adjusting handle 2-2-3 is a regular hexagonal prism, which is integrally fixed and connected with the intermediate connecting rod.

[0059] Specific Embodiment Seven: This embodiment is a further limitation of Embodiment Six. A placement groove 5 corresponding to and matching with the support pipe 1 is machined on the arc surface of the diameter-changing seat body 2-3-3.

[0060] Further, the placement groove 5 is used to place the support pipe 1. The shape of the inner part of the placement groove 5 is matched with the outer shape of the support pipe 1, and the preferred shape of the placement groove 5 is a square groove.

[0061] Further, the distance between two adjacent placement grooves 5 determines the distance between two adjacent support pipes 1. In order to ensure the smoothness of the present invention and that the support plate 4-2 passes through the gap between the support pipes, the thickness of the support plate 4-2 ranges from 5 mm to 15 mm, and the optimal value is 10 mm. Considering the processing error and quick assembly, the distance between two adjacent placement grooves 5 is preferably set at 20 mm to ensure the rapid and smooth assembly process, facilitate the quick loading and unloading of the present invention, and thus contribute to the effect of quick demolding of the present invention.

[0062] Embodiment 8 of specific implementation manners: This embodiment is a further limitation of Embodiment 7. The two ends of the adjacent variable-diameter seat body 2-3-3 in the circumferential direction are respectively lapping ends, and the lapping length of the two adjacent lapping ends of the two adjacent variable-diameter seat bodies 2-3-3 is the maximum circumferential adjustment distance between the two adjacent variable-diameter seat bodies 2-3-3, that is, the maximum circumferential adjustment distance at the connection of the two adjacent variable-diameter seat bodies 2-3-3.

[0063] Further, as Figure 10 and Figure 11 shown, the multiple variable-diameter seat bodies 2-3-3 include multiple first seat bodies and multiple second seat bodies. The multiple first seat bodies and the multiple second seat bodies are alternately arranged. Upper grooves 6 are machined on the top surfaces of the two lapping ends of each first seat body, positioning holes 7 are machined at the bottoms of each upper groove 6, lower grooves 8 are machined on the bottom surfaces of the two lapping ends of each second seat body, and the first seat body is lapped with the lower groove 8 of the second seat body through the upper groove 6. The multiple first seat bodies and the multiple second seat bodies are alternately arranged along the circumferential direction of the central hub 2-1. Such a setting can avoid the clamping and collision of the first seat body and the second seat body during the loading and unloading process, ensure the rapid assembly of the first seat body and the second seat body, without the harsh requirement of simultaneous assembly at multiple places at the same time. It can be loaded and unloaded in sequence along the circumferential direction of the arrangement of the multiple first seat bodies and the multiple second seat bodies, saving manpower, reducing the assembly difficulty, and providing a favorable structural condition for realizing rapid demolding.

[0064] Further, the number of the first seat bodies is the same as that of the second seat bodies.

[0065] Further, upper grooves 6 are arranged at both ends of the first seat body, and lower grooves 8 are arranged at both ends of the second seat body adjacent thereto to realize the lapping fit between the first seat body and the other two adjacent second seat bodies. The machining position of the upper groove 6 is along the top surface of the lapping end. The upper groove 6 is provided with a positioning hole 7 for adding an auxiliary component to provide an installation and connection position when the gap between two adjacent support pipes 1 is too large during variable diameter, without the need to disassemble and reassemble the support pipe 1 again, which is beneficial to ensuring that the overall structure can still ensure sufficient smoothness while upgrading and expanding the diameter.

[0066] Further, the lower groove 8 is machined along the bottom surface of the lapping end, and is only used to extend the arc structure form of the support seat 2-3 during the variable diameter process in combination with the upper groove 6.

[0067] Further, through the mutual cooperation of the upper groove 6 and the lower groove 8, the support effect after variable diameter between the multiple support seats 2-3 is effectively improved, and the manufacturing accuracy and smoothness are ensured.

[0068] Further, the preferred connection method when connecting the adjacent variable-diameter seat bodies 2-3-3 is lapping.

[0069] Specific Embodiment IX: This embodiment is a further limitation of Embodiment I, II, III, IV, V, VI, VII or VIII. The support pipe 1 is a square pipe, and a fastening rope 9 is threaded through between multiple support pipes 1, and a fastening device 10 is provided in cooperation with the fastening rope 9.

[0070] In this embodiment, through holes for cooperating with the fastening rope 9 are respectively machined on both side surfaces of the support pipe 1, and the two through holes are arranged in the same direction.

[0071] In this embodiment, the fastening rope 9 is an existing inelastic rope body with stable toughness. The fastening method of the fastening rope 9 is that one end of the fastening rope 9 is arranged on the fastening device 10, and the other end of the fastening rope 9 sequentially passes through multiple support pipes 1 and then winds around the outer walls of the multiple support pipes 1 at least one circle again and is connected to the fastening device 10.

[0072] Further, the fastening device 10 is an existing fastening product for extending or shortening the rope loop, which can be obtained by market purchase.

[0073] Further, the number of fastening loops of the fastening rope 9 is at least two, and the setting positions of the number of fastening loops are respectively arranged in an inner-passing setting and an outer-wrapping setting.

[0074] Specific Embodiment X: This embodiment is a further limitation of Embodiment VIII or IX. When the circumferential adjustment distance matches the diameter of the support pipe 1, a special-shaped pipe 11 is arranged between the two lapping ends of two adjacent variable-diameter seat bodies 2-3-3. The shape of the special-shaped pipe 11 is the same as that of the support pipe 1, and a notch 12 for cooperating with the fastening rope 9 is machined at the end of the special-shaped pipe 11 along its length direction.

[0075] Further, the first seat body is lapped with the lower groove 8 of the second seat body through the upper groove 6, and a spatial position for cooperating with the special-shaped pipe 11 is formed therebetween. The positioning hole 7 is used to fix the position of the special-shaped pipe 11 to ensure the smoothness of the overall structure.

[0076] Further, a limiting block 15 is arranged on the outer end surface of the special-shaped pipe 11 facing the lapping end of the variable-diameter seat body 2-3-3, and the limiting block 15 and the positioning hole 7 on the upper groove 6 are detachably connected through a positioning pin 14.

[0077] Further, the notch 12 is used to provide a threading position for the fastening rope 9, the positioning pin 14 is used to fix the circumferential position of the special-shaped pipe 11, and the limiting block 15 is used to fix the radial position of the special-shaped pipe 11, which is beneficial to ensuring the smooth arrangement process of the fastening rope 9 without changing other support pipes 1. The mutual cooperation of the limiting block 15 and the positioning pin 14 can also ensure that the special-shaped pipe 11 and the support pipe 1 are on the same height cylindrical surface.

[0078] Embodiment XI: This embodiment is a further limitation of Embodiment I, II, III, IV, V, VI, VII, VIII or IX. In the present invention, the structure of the end-face type support frame 2 is ingeniously designed, which can achieve its own diameter-changing effect. The basic diameter can be set to 1000 mm or 2000 mm, increasing in increments of 120 mm. The diameter-changing range is that the optimal diameter adjustment amount is within the range of 360 / π mm, which can meet the radial dimension requirements of most current reactors, has universality, greatly saves costs, and solves the single drawback that one reactor corresponds to one mold. At the same time, the diameter-changing effect achieved by the mutual cooperation between the central hub 2-1, multiple adjusting rods 2-2 and multiple support seats 2-3 is stable, and it can cooperate with the circumferential support assembly to ensure the smoothness of the outer circumferential surface after diameter change, providing a favorable basis for producing high-quality and unified products. The relevant design parameters of the present invention are as follows:

[0079] Determination of the dimensions of the end-face type support frame 2:

[0080] Fixed dimension X: including the shaft radius X1 of the connecting shaft 3 = 50 mm, the hub thickness X2 of the central hub 2-1 = 20 mm, the thickness X3 of the diameter-changing seat body 2-3-3 = 70 mm, the length X4 of the adjusting handle 2-2-3 = 60 mm, and the demoulding clearance dimension X5 = 10 mm. Therefore, X = X1 + X2 + X3 + X4 + 2*X5 = 220 mm.

[0081] To ensure a certain connection strength, the minimum dimension y of the internal and external thread connection = 50 mm.

[0082] Calculate other structural dimensions according to the basic diameter dimension d.

[0083] The lengths a of the first internal thread and the second internal thread are equal, a = (d / 2 - X) / 2 = (d / 2 - 220) / 2 = d / 4 - 110;

[0084] The lengths b of the first external thread and the second external thread are equal, b = a - X5 = d / 4 - 110 - 10 = d / 4 - 120;

[0085] The length of the adjusting rod 2-2: c = 2(b + X5) + X4 = 2(d / 4 - 120 + 10) + 60 = d / 2 - 160.

[0086] Specifically, there are several ways:

[0087] The adjustable radius increment of one type of size adjusting rod 2-2: R = d / 2 - X - 2y = d / 2 - 220 - 100 = d / 2 - 320;

[0088] The fine-tuning radius increment of each diameter-changing seat body 2-3-3: t = (s + k)*n / (2π),

[0089] In the above formula, s is the width of the support tube 1, and through calculation and sample testing, it is determined that the optimal value of s is 40 mm; k is the gap between two adjacent support tubes 2, and through calculation and sample testing, it is determined that the optimal value of k is 20 mm; n is the number of end - face type support frames 2, and through calculation and sample testing, it is determined that the optimal value of n is 6. Therefore, t = 360 / (2π) = 57.32 mm.

[0090] The number of a kind of size - adjusting rod 2 - 2 that can cooperate with the variable - diameter seat body 2 - 3 - 3: w = R / t

[0091] Taking the basic diameter size d = 1000 mm as an example, the dimensions of the structural parts are as follows:

[0092] The lengths of the first internal thread and the second internal thread a are equal, a = 1000 / 4 - 110 = 140 mm;

[0093] The lengths of the first external thread and the second external thread b are equal, b = 1000 / 4 - 120 = 130 mm;

[0094] The length of the adjusting rod 2 - 2: c = 1000 / 2 - 160 = 340 mm;

[0095] The adjustable radius increment of the adjusting rod 2 - 2: R = 1000 / 2 - 320 = 180 mm;

[0096] Each variable - diameter seat body 2 - 3 - 3 can finely adjust the radius increment t = 57.32 mm. Therefore, w = 180 / 57.32 = 3.14, and taking the integer w = 3. The number of variable - diameter seat bodies 2 - 3 - 3 is 3. When forming a series, taking t = 60 mm, the diameters of the adjusting rod 2 - 2 corresponding to the basic diameter size d = 1000 mm for the variable - diameter seat bodies 2 - 3 - 3 are 1000 mm, 1120 mm, and 1240 mm respectively, and the corresponding adjustment ranges are 1000 - 1120 mm, 1120 - 1240 mm, and 1240 - 1360 mm respectively.

[0097] To further increase the adjustable diameter, the dimension of the length of the adjusting rod 2 - 2 needs to be changed. The length of the adjusting rod 2 - 2 c = 340 mm, with an increment of R = 180 mm, and each increment can still correspond to the diameters of 3 variable - diameter seat bodies 2 - 3 - 3. Since the variable - diameter seat body 2 - 3 - 3 is an arc - shaped seat body, the diameter of the variable - diameter seat body 2 - 3 - 3 refers to the diameter corresponding to the outer - circle surface where the variable - diameter seat body 2 - 3 - 3 is located.

[0098] Therefore, the diameter series of the variable - diameter seat body 2 - 3 - 3 is based on 1000 mm and increases by 120 mm; the length of the adjusting rod 2 - 2 c = 340 mm is the base and increases by 180 mm; one length of the adjusting rod 2 - 2 can correspond to the diameters of 3 variable - diameter seat bodies 2 - 3 - 3.

[0099] Specific Embodiment Twelve: This embodiment further limits Embodiment Eleven. The component dimensions are redesigned according to the formula mentioned in Embodiment Eleven, so as to correspond to more diameter series of the variable-diameter seat body 2-3-3.

[0100] Taking the basic diameter dimension d = 2000mm as an example,

[0101] The lengths a of the first internal thread and the second internal thread are equal, a = 2000 / 4 - 110 = 390mm;

[0102] The lengths b of the first external thread and the second external thread are equal, b = 2000 / 4 - 120 = 380mm;

[0103] The length of the adjusting rod 2-2: c = 2000 / 2 - 160 = 840mm;

[0104] The adjustable radius increment of the adjusting rod 2-2: R = 2000 / 2 - 320 = 680mm.

[0105] The adjustable radius increment t of each variable-diameter seat body 2-3-3 is 60mm, w = R / t = 11.33. To ensure load-bearing safety and accuracy, take w = 10. The number of variable-diameter seat bodies 2-3-3 is 10. Therefore, the diameter ranges of the variable-diameter seat bodies 2-3-3 are 2000~2120mm, 2120~1240mm, 1240~1360mm,..., 3080~3200mm respectively. Since the variable-diameter seat body 2-3-3 is an arc-shaped seat body, the diameter of the variable-diameter seat body 2-3-3 refers to the diameter corresponding to the outer circular surface where the variable-diameter seat body 2-3-3 is located.

[0106] The variable-diameter seat body 2-3-3 series is based on 2000mm and increases by 120mm, so 10 series can be formed.

[0107] Thus, it shows that the end-face type support frame 2 of the present invention can form multiple structural forms through the deformation effect to cooperate with different types of reactors, quickly demold, and greatly save the processing cost of manufacturing reactors.
