Description

Technical Field

[0001] This utility model belongs to the field of nuclear fusion device technology, and specifically relates to a support device for stellarator coils. Background Technology

[0002] Superconducting coils are key components of nuclear fusion devices. They generate strong magnetic fields to confine high-temperature plasma, preventing it from contacting the device walls and maintaining a stable plasma state to promote the nuclear fusion reaction. Common nuclear fusion devices include tokamas and stellarators. In nuclear fusion applications, the suitability and performance of the support system for the superconducting coils affect their stability and reliability. Particularly for the irregularly shaped superconducting coils in stellarators, the requirements for the support system are even higher. The precision, stability, adjustability, and versatility of the support system in placing the coils have a crucial impact on subsequent work such as insulation, testing, connector treatment, and accessory installation for the stellarator's superconducting coils.

[0003] However, the existing support devices for stellarator coils have many shortcomings, including: (1) poor adaptability and poor versatility. For example, there are many different shapes of superconducting coils in stellarators, and traditional support devices are difficult to adapt to the installation requirements of superconducting coils of different shapes; (2) insufficient adjustment flexibility. During installation and use, the position of the superconducting coil cannot be adjusted flexibly, and the required position cannot be accurately achieved. In addition, support fixtures need to be configured on-site according to the different shapes of superconducting coils, resulting in poor adaptability. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor adaptability, poor versatility, and insufficient adjustment flexibility of existing support devices for stellarator coils.

[0005] To address the aforementioned technical problems, this utility model discloses a support device for a stellarator coil. The stellarator coil is a non-planar annular coil, and the support device includes a support platform and multiple support columns. The support platform is arranged in an annular structure. Multiple support columns are spaced apart circumferentially on the top surface of the support platform, and each support column extends along the thickness direction of the support platform. The bottom end of each support column is fixedly connected to the top surface of the support platform, and its top end is fixedly connected to a surface of the stellarator coil along its thickness direction. The bottom end of each support column is adjustable relative to the support platform in its circumferential direction, so that the top end of the support column is adjustable relative to the stellarator coil in its circumferential direction. Furthermore, each support column includes a fixed column, a lifting column, and a connecting seat. The lifting column is connected to the fixed column, and its position relative to the fixed column in its length direction is adjustable, so that the distance between the top end of the support column and the top surface of the support platform is adjustable. The bottom end of the fixed column constitutes the bottom end of the support column, the lower end of the connecting seat is rotatably connected to the top end of the lifting column, and the upper end of the connecting seat constitutes the top end of the support column.

[0006] The above-described scheme utilizes multiple support columns working together, combined with a bottom support platform, to ensure the stability of the stellarator coil. Each support column in the support device can be adjusted circumferentially relative to the bottom support platform, and also vertically, providing high flexibility and suitability for mounting irregularly shaped stellarator coils. Furthermore, the stellarator coil can be adaptively adjusted after being mounted on the connector of each support column, allowing for rotational adjustment of the complex contact surface between the top of the support column and the irregularly shaped stellarator coil to achieve a close connection, improving support stability. This also allows for adaptation to the bottom surfaces of stellarator coils of different shapes, enhancing the adaptability of the support device.

[0007] According to another specific embodiment of the present invention, the support device for a stellarator coil disclosed in this embodiment includes a lifting column comprising a guide cylinder and a lifting rod connected to the guide cylinder; the guide cylinder is sleeved inside a fixed column and can pass through the top of the fixed column and gradually rise towards the outside of the fixed column or gradually descend towards the inside of the fixed column; the lifting rod extends along the length direction of the support column and passes through the guide cylinder, and the lifting rod is connected to the fixed column; the support column is provided with an adjustment component, which is drivenly connected to the lifting rod and is used to drive the lifting rod to rise or fall relative to the fixed column, so as to adjust the fixed position of the lifting column relative to the fixed column in its length direction.

[0008] Using the above scheme, the cooperative structure of the guide cylinder and the fixed column plays a role in lifting and guiding, and the lifting column can be fixed in its length direction relative to the fixed column through the lifting rod; the support column structure has strong integrity and is simple and easy to operate.

[0009] According to another specific embodiment of the present invention, the support device for stellarator coil disclosed in this embodiment of the present invention has a gap between the outer wall surface of the guide cylinder and the inner wall surface of the fixed column, and a lubricant is provided in the gap, the width of the gap being 0.05mm-0.1mm.

[0010] The above solution improves the sliding ability between the outer wall of the guide cylinder and the inner wall of the fixed column.

[0011] According to another specific embodiment of the present invention, the support device for stellarator coil disclosed in this embodiment of the present invention has a lifting rod as a first lead screw; the adjustment component includes a first turbine and a worm gear; the first turbine is disposed in a fixed column and is rotatably connected to the fixed column; the first lead screw is fixedly connected to the guide cylinder and is drivenly connected to the first turbine; when the worm gear rotates, it drives the first turbine to rotate, and the first lead screw rises or falls relative to the fixed column through the linkage of the first turbine.

[0012] The above scheme uses a worm gear transmission structure to drive the lead screw for lifting, thereby realizing the lifting of the column. It can achieve fine adjustment of the lifting column, with a simple structure and high adjustment accuracy.

[0013] According to another specific embodiment of the present invention, the support device for stellarator coil disclosed in this embodiment of the present invention has a first lead screw extending out of the upper end of the guide cylinder, and the upper end of the first lead screw forms the top of the lifting column and is ball-jointed to the lower end of the connecting seat.

[0014] By adopting the above scheme, the connecting seat can rotate freely in three-dimensional space around the X, Y, and Z axes relative to the lifting column, which provides high adjustment flexibility.

[0015] According to another specific embodiment of the present invention, the support device for stellarator coil disclosed in this embodiment of the present invention further includes a handwheel in the adjustment component. The handwheel is disposed outside the fixed column and is connected to one end of the worm gear for transmission.

[0016] Using the above solution, height adjustment can be driven by a handwheel, making operation simple and efficient.

[0017] According to another specific embodiment of the present invention, the support device for stellarator coil disclosed in this embodiment of the present invention includes a fixed column comprising a base and a fixed cylinder connected sequentially in its length direction. The upper end of the base is fixedly connected to the lower end of the fixed cylinder, and the lower end of the base is fixedly connected to the top surface of the support platform, forming the bottom end of the fixed column. The upper end of the fixed cylinder forms the top end of the fixed column. A guide cylinder is sleeved inside the fixed cylinder. A first worm gear is disposed inside the base and rotatably connected to the base. A first lead screw also extends into the base from the upper end of the base. A worm gear is disposed on the base and can rotate relative to the base.

[0018] The above scheme uses a two-part fixed column, with the upper fixed cylinder slidingly engaging with the guide cylinder, and the lower base housing the first turbine, which improves the support stability of the fixed column.

[0019] According to another specific embodiment of the present invention, the support device for stellarator coil disclosed in this embodiment of the present invention has an adjusting waist hole group provided at the position corresponding to the support column on the top surface of the support platform. The adjusting waist hole group includes at least two adjusting waist holes that are parallel to each other and spaced apart, and each adjusting waist hole extends along the circumference of the support platform. By fixing the bottom end of the fixed column to different positions of the adjusting waist hole, the fixed connection position between the bottom end of the fixed column and the support platform is adjustable in the circumference of the support platform.

[0020] The above solution allows for horizontal adjustment of the support column relative to the support platform by setting adjustment holes. The structure is simple, and the operation is simple and efficient, enabling rapid adjustment.

[0021] According to another specific embodiment of the present invention, the support device for stellarator coils disclosed in this embodiment includes a support column with a movable component. The movable component includes two supports, a second lead screw, and a second turbine. The two supports are fixedly mounted on the top surface of the support platform and are respectively mounted on both sides of the support column. The second turbine is mounted inside a fixed column and is rotatable relative to the fixed column. The second lead screw extends in a direction perpendicular to the length direction of the support column, passes through the fixed column, and is drively connected to the second turbine. Both ends of the second lead screw are fixedly connected to the two supports. When the second turbine rotates, it drives the fixed column to move along the second lead screw. The fixed column includes a base and a fixed cylinder. When the support column is equipped with an adjustment component, the second turbine is mounted inside the base, and the second lead screw passes through the base. In the length direction of the fixed column, the second turbine is located below the first turbine of the adjustment component.

[0022] The above scheme uses a worm gear transmission structure to drive the support column to translate along the support platform. With the help of adjusting the waist hole, the translation of the support column can be finely adjusted. The operation is simple and labor-saving, and the adjustment accuracy is high.

[0023] According to another specific embodiment of the present invention, the support device for a stellarator coil disclosed in this embodiment has a strip-shaped hole extending along the length of the fixed column on the side wall of the fixed column; one end of the worm gear passes through the strip-shaped hole, and the worm gear can switch between a first adjustment position and a second adjustment position relative to the strip-shaped hole; when the worm gear is in the first adjustment position, the worm gear is driven to a first worm gear to drive the lifting column to rise or fall relative to the fixed column; when the worm gear is in the second adjustment position, the worm gear is driven to a second worm gear to drive the second worm gear to rotate through the rotation of the worm gear, thereby moving the fixed column along the second lead screw, and driving the support column to move relative to the support platform along the circumference of the support platform.

[0024] The above scheme uses a worm gear to drive the bottom end of the support column to move relative to the support platform in its circumferential direction, and to drive the lifting column to rise and fall relative to the fixed column in its length direction. This simplifies the structure of the support device and allows for quick switching of the drive position through the slotted hole, making the operation simple and efficient.

[0036] To better understand the support device for stellarator coils provided in this application, the specific structure of the support device for stellarator coils will be described in detail below with reference to the accompanying drawings.

[0037] This invention provides a support device for a stellarator coil, wherein the stellarator coil is a non-planar toroidal coil. Specifically, the stellarator uses an external irregularly shaped coil to generate a twisted toroidal magnetic cage to avoid induced current saturation and achieve more stable long-term operation. Stellarator coils can have different shapes, such as... Figures 1-3The shapes of three different stellarator irregular coils are shown, all of which are non-planar toroidal coils.

[0038] like Figure 4 As shown, the support device 1 for a stellarator coil provided by this utility model includes a support platform 11 and multiple support columns 12. The support platform 11 is arranged in a ring structure, and this ring structure corresponds to the ring of the stellarator coil 2. The support platform 11 plays a basic supporting role in the support device 1, and is used to support the multiple support columns 12 and the stellarator coil 2. The support platform 11 also provides an installation base for the multiple support columns 12. The multiple support columns 12 are arranged at intervals along the circumference of the ring structure of the support platform 11 on the top surface of the support platform 11, and each support column 12 extends along the thickness direction of the support platform 11, which is also the height direction when the support device 1 is set on the ground. The bottom end of each support column 12 is fixedly connected to the top surface of the support platform 11, and the top end is used to be fixedly connected to a surface of the stellarator coil 2 along its thickness direction (consistent with the thickness direction of the support platform 11). The specific fixing connection method can be screwing, riveting, etc., with screwing being preferred, which facilitates the disassembly of the stellarator coil 2. Through the above structure, multiple support columns 12 work together to support the stellarator coil 2, combined with the bottom support platform 11, ensuring the stability of the stellarator coil 2. The support device 1 can be made of high-strength steel, and the size and material of the support platform 11 are designed according to the size, weight and other parameters of the stellarator coil 2. The size, material and number of multiple support columns 12 are also designed. The number of support columns 12 can be 4, 5, 6 or more, as long as the final support device 1 can stably support the stellarator coil 2.

[0039] like Figures 4-6 As shown, each support column 12 includes a fixed column 121, a lifting column 122, and a connecting seat 123. The bottom end of the fixed column 121 forms the bottom end of the support column 12, and the upper end of the connecting seat 123 forms the top end of the support column 12. Specifically, the lifting column 122 is mounted on the fixed column 121, and its external shape can be cylindrical, cubic, or other shapes, as long as it has sufficient strength and can achieve lifting. The upper end of the connecting seat 123 is used for fixed connection with the stellarator coil 2, and is therefore set as a planar structure to match the bottom surface of the stellarator coil 2 and provide support. The upper end of the connecting seat 123 can specifically be a circular, square, or other polyhedral planar structure. Figure 5 The structure is shown as a circular planar structure, but its specific shape can be set as needed; this embodiment does not impose a specific limitation. The fixed column 121 can be a single cylinder, cube, or other stable structure with sufficient supporting strength; it can also be a structure formed by connecting multiple different shapes together. In one specific embodiment, such as... Figures 4-6As shown, the fixing column 121 includes a base 1211 and a fixing cylinder 1212 connected sequentially along its length (i.e., height). The upper end of the base 1211 is fixedly connected to the lower end of the fixing cylinder 1212, and the lower end of the base 1211 is fixedly connected to the top surface of the support platform 11, forming the bottom end of the fixing column 121. The upper end of the fixing cylinder 1212 forms the top end of the fixing column 121. Further, as... Figure 5 As shown, the base 1211 is a cube structure with six basically closed sides, and the fixing cylinder 1212 is a cylindrical structure with open ends. The diameter of the fixing cylinder 1212 is smaller than the length and width of the base 1211. The bottom end of the fixing cylinder 1212 is fixedly connected to the top end of the base 1211, which can be achieved by welding.

[0040] Furthermore, to improve the adjustment flexibility of the support device 1 to accommodate the installation requirements of the stellarator coil 2, each support column 12 is configured such that its bottom end (i.e., the bottom end of the fixed column 121) is adjustable relative to the support platform 11 in its circumferential direction, so that the top end of the support column 12 is adjustable relative to the stellarator coil 2 in its circumferential direction; and, the lifting column 122 is connected to the fixed column 121, and the lifting column 122 is adjustable relative to the fixed column 121 in its length direction, so that the distance between the top end of the support column 12 and the top surface of the support platform 11 is adjustable; the lower end of the connecting seat 123 is rotatably connected to the top end of the lifting column 122, so that the connecting seat 123 (forming the top end of the support column 12) can also rotate relative to the main body of the support column 12 (fixed column 121 and lifting column 122).

[0041] Using the above scheme, each support column 12 in the support device 1 can be adjusted circumferentially relative to the bottom support platform 11, and the support column 12 itself can also be adjusted in the height direction. The support device 1 has strong adjustment flexibility and adaptability, and is suitable for installing stellarator coils with irregular shapes. Specifically, since the stellarator coil 2 is a non-planar ring coil, when it is set on the support device 1, some parts are relatively smooth relative to the horizontal plane, which is suitable for setting the support column 12, while some parts have a large angle change relative to the horizontal plane, which is not suitable for setting the support column 12. In this case, the relative positions of multiple support columns 12 can be adjusted circumferentially along the support platform 11 so that the support column 12 is set in the relatively smooth part of the coil, so as to stably support the stellarator coil 2. Furthermore, when it is set on the support device 1, the distance between different positions of the bottom of the stellarator coil 2 and the support platform 11 varies. In this case, the distance between the top of the support column 12 and the top surface of the support platform 11 can be adjusted to adjust the height of different support columns 12, thereby adapting to different distances. Furthermore, the top connecting seat 123 of each support column 12 can also rotate relative to the main body of the support column 12 (fixed column 121 and lifting column 122). After the stellarator coil 2 is set on the connecting seat 123, it can be adaptively adjusted to realize the complex contact surface between the top of the support column 12 and the stellarator coil with different shapes to fit and connect, improve the support stability, and can be adapted to the bottom surface of stellarator coil 2 with different shapes, thus improving the adaptability of the support device 1.

[0042] The connection structure of the support device for stellarator coils provided by this utility model will be further described in detail below.

[0043] The position of the lifting column 122 relative to the fixed column 121 along its length is adjustable, so that the distance between the top of the support column 12 and the top surface of the support platform 11 is adjustable. The lifting column 122 can be a structure including a hydraulic rod, a pneumatic rod, or a lead screw. Specifically, the lifting column 122 can be designed as a hydraulic cylinder or pneumatic cylinder structure, including hydraulic cylinders or pneumatic cylinders. Alternatively, a hydraulic cylinder or pneumatic cylinder can be installed in the lifting column 122, which is driven to lift and lower, thereby driving other parts to lift and lower. Alternatively, a liftable lead screw can be installed in the lifting column 122, which is driven to lift and lower, thereby driving other parts to lift and lower.

[0044] In one specific implementation, such as Figures 5-6 As shown, the lifting column 122 includes a guide cylinder 1221 and a lifting rod connected to the guide cylinder 1221 (in... Figures 5-6(The first lead screw 1222 is shown in the image). The guide cylinder 1221 is sleeved inside the fixed column 121 and can pass through the top of the fixed column 121 and gradually rise towards the outside of the fixed column 121 or gradually descend towards the inside of the fixed column 121. The cooperative structure of the guide cylinder 1221 and the fixed column 121 plays a guiding role in lifting and lowering, and the overall structure of the support column 121 is strong. Specifically, the shape of the guide cylinder 1221 matches the shape of the upper end of the fixed column 121. For example, if the upper end of the fixed column 121 is cubic or cylindrical, the guide cylinder 1221 is a matching structure of the same shape but slightly smaller in size. When the fixed column 121 includes a base 1211 and a fixed cylinder 1212 connected sequentially in its length direction, the guide cylinder 1221 is located inside the fixed cylinder 1212, and its shape and size match those of the fixed cylinder 1212. When the fixed cylinder 1212 is as follows... Figures 4-6 When the cylinder shown is cylindrical, the guide cylinder 1221 is also cylindrical.

[0045] The lifting rod extends along the length of the support column 12 and passes through the guide cylinder 1221, and is connected to the fixed column 121; the lifting rod can be a hydraulic cylinder, a pneumatic cylinder, or a lead screw. Figures 5-6 (shown as a lead screw); the support column 12 is provided with an adjustment component 124, which is connected to the lifting rod for driving the lifting rod to rise or fall relative to the fixed column 121, so as to adjust the fixed position of the lifting column 122 relative to the fixed column 121 in its length direction; and, for hydraulic cylinders or pneumatic cylinders, the adjustment component 124 may specifically include a hydraulic pump or a pneumatic pump, etc.; for lead screws, the adjustment component 124 may include a worm gear, etc.

[0046] Furthermore, in one specific embodiment, there is a gap between the outer wall surface of the guide cylinder 1221 and the inner wall surface of the fixing column 121, and a lubricant is provided in the gap to improve the sliding ability. The width of the gap is 0.05mm-0.1mm.

[0047] Furthermore, in one specific implementation, such as Figures 5-6 As shown, the lifting rod is a first lead screw 1222; the adjusting assembly 124 includes a first turbine 1241 and a worm gear 1242; the first turbine 1241 is disposed inside the fixed column 121 and is rotatably connected to the fixed column 121; the first lead screw 1222 is fixedly connected to the guide cylinder 1221 and is drively connected to the first turbine 1241; when the worm gear 1242 rotates, it drives the first turbine 1241 to rotate, and the first lead screw 1222 rises or falls relative to the fixed column 121 through the first turbine 1241. Wherein, as... Figures 5-6As shown, when the fixed column 121 includes a base 1211 and a fixed cylinder 1212 connected sequentially in its length direction, the first worm gear 1241 is disposed in the base 1211 and rotatably connected to the base 1211, the first lead screw 1222 extends into the base 1211 from the upper end of the base 1211, and the worm gear 1242 is disposed in the base 1211 and can rotate relative to the base 1211.

[0048] Specifically, such as Figures 5-6 As shown, a first turbine connecting seat 1243 can be provided inside the fixed column 121, and the first turbine connecting seat 1243 is fixedly connected to the inner wall of the fixed column 121, specifically by bolts. The first turbine 1241 is then rotatably connected to the first turbine connecting seat 1243 via bearings. The upper end of the first lead screw 1222 is fixedly connected to the guide cylinder 1221, and the lower end of the first lead screw 1222 passes through the central hole of the first turbine 1241 and is connected to the central hole of the first turbine 1241 via a matching threaded structure. Wherein, for example... Figures 5-6 As shown, when the fixed column 121 includes a base 1211 and a fixed cylinder 1212 connected sequentially along its length, the first turbine connecting seat 1243 can be disposed at the upper end of the base 1211 and fixedly connected to the inner wall of the upper end of the base 1211. The lower end of the first lead screw 1222 passes through the upper end of the base 1211 and enters the central hole of the first turbine 1241. The outer periphery of the first turbine 1241 is connected by meshing with the worm gear 1242. At least one end of the worm gear 1242 can be supported by a connecting shaft seat 1244 disposed on the side wall of the fixed column 121. The worm gear 1242 and the connecting shaft seat 1244 are connected by a bearing. One end of the worm gear 1242 can be disposed outside the fixed column 121 through the side wall of the fixed column 121. The worm gear 1242 can be driven to rotate manually, or one end of the worm gear 1242 can be connected to a motor, and the worm gear 1242 can be driven to rotate by the rotation of the motor.

[0049] In one specific implementation, such as Figures 4-6 As shown, the adjustment assembly 124 also includes a handwheel 1245, which is located outside the fixed column 121 and is connected to one end of the worm gear 1242 via a spline connection. The worm gear 1242 can be driven to rotate by manually turning the handwheel 1245.

[0050] Traditional support devices are structurally rigid, making it difficult to adjust for minute positional deviations after supporting a superconducting coil, thus hindering high-precision and stable adjustment. The aforementioned setup utilizes a worm gear transmission structure to drive the first lead screw 1222 to rise and fall, thereby raising and lowering the lifting column 122. Combined with the sliding guide between the guide cylinder 1221 and the fixed column 121, fine-tuning of the lifting column 122's rise and fall can be achieved, resulting in a simple structure and high adjustment precision. Furthermore, height adjustment can be driven via the handwheel 1245, making operation simple and efficient.

[0051] The lower end of the connecting seat 123 is rotatably connected to the top end of the lifting column 122. Specifically, it can be configured such that the lower end of the connecting seat 123 is hinged to the top end of the lifting column 122. Further, in a specific embodiment, such as... Figure 5 and Figure 7 As shown, the lower end of the connecting seat 123 is connected to the top end of the lifting column 122 via a ball joint. Furthermore, the first lead screw 1222 extends through the upper end of the guide cylinder 1221 and is fixedly connected to the upper end of the guide cylinder 1221, specifically through welding. The upper end of the first lead screw 1222 forms the top end of the lifting column 122 and is ball joint connected to the lower end of the connecting seat 123. Furthermore, a ball head structure can be provided at the upper end of the first lead screw 1222, and a matching ball socket structure can be provided at the lower end of the connecting seat 123 to achieve a ball joint connection. And, as... Figure 7 As shown, the top of the connector 123 is detachably connected to the connector block 21 of the stellarator coil 2 via a bolt assembly.

[0052] The ball joint connection described above enables a rotatable connection, allowing the connecting seat 123 to rotate freely around the X, Y, and Z axes in three-dimensional space relative to the lifting column 122, resulting in high adjustment flexibility.

[0053] The bottom end of each support column 12 is adjustable relative to the support platform 11 in its circumferential fixed position. The bottom end of the support column 12 can be connected to the top surface of the support platform 11 via a matching slide rail and slider to achieve adjustment, and a corresponding locking structure can be provided to achieve a fixed connection between the support column 12 and the support platform 11. Alternatively, multiple fixed connection positions can be provided on the top surface of the support platform 11, and the position of the support column 12 can be adjusted by connecting the bottom end of the support column 12 to different fixed connection positions. More specifically, multiple sets of screw holes can be provided circumferentially at intervals on the top surface of the support platform 11, each set containing 2, 4, 6, etc., and matching screw structures can be provided on the outer periphery of the bottom end of the support column 12, allowing the bottom end of the support column 12 to be fixedly connected to different sets of screw holes via bolts to adjust the fixed position of the support column 12 relative to the support platform 11 in its circumferential direction.

[0054] In one specific implementation, such as Figure 4 and Figure 8As shown, each support column 12 has an adjustable waist hole group on its top surface corresponding to an adjustable waist hole group. Each support column 12 has one adjustable waist hole group, and multiple groups are distributed along the support column 12, with the holes spaced apart circumferentially along the support platform 11. Each adjustable waist hole group includes at least two parallel and spaced adjustable waist holes 111, and each adjustable waist hole 111 extends circumferentially along the support platform 11. It should be noted that each adjustable waist hole 111 is an elongated waist hole. The bottom end of the fixed column 121 is provided with a corresponding threaded connection structure, as shown in the figure. Figures 4-6 as well as Figure 8 As shown, a connecting plate extending outward and perpendicular to the height direction of the fixing post 121 is provided on the outer periphery of the bottom end of the fixing post 121. Multiple threaded connection holes are provided on the connecting plate. Furthermore, it can be configured as follows: Figures 5-6 and Figure 8 As shown, each threaded connection hole is also configured as a short waist hole with an extension direction consistent with that of the adjusting waist hole 111, to facilitate adjustment of the fixed connection position. By fixing the bottom end of the fixed column 121 to different positions of the adjusting waist hole 111, the fixed connection position between the bottom end of the fixed column 121 and the support platform 11 is adjustable in the circumferential direction of the support platform 11. Adjustment is achieved by setting the adjusting waist hole 111, resulting in a simple structure, easy and efficient operation, and rapid adjustment. It should be noted that, as needed, adjusting waist hole groups can also be set only on the top surface of the support platform 11 corresponding to some of the support columns 12; or more adjusting waist hole groups can be set on the top surface of the support platform 11 than on the support columns 12, allowing the support columns 12 to be adjusted to a wider range on the top surface of the support platform 11.

[0055] Furthermore, to facilitate adjustment of the fixed connection position of the support column 12, such as... Figure 4 and Figure 8 As shown, the support platform 11 can be made of standard I-beams, with one side surface of the I-beam forming the top surface.

[0056] Furthermore, in another specific implementation, such as Figure 4 , Figure 6 and Figure 9 As shown, the support column 12 is equipped with a movable component 13, which includes two supports 131, a second lead screw 132, and a second turbine 133. The two supports 131 are fixedly mounted on the top surface of the support platform 11 and are respectively located on both sides of the support column 12. Specifically, the two supports 131 can be fixedly connected to the top surface of the support platform 11 by welding, screwing, riveting, etc. Figure 6 and Figure 9As shown, the second turbine 133 is disposed within the fixed column 121 and is rotatable relative to the fixed column 121. It should be noted that the second turbine 133 is disposed at the bottom end of the fixed column 121. Specifically, similar to the arrangement of the first turbine 1241, a second turbine connecting seat 134 can also be disposed within the fixed column 121, and the second turbine connecting seat 134 is fixedly connected to the inner wall of the fixed column 121. When the fixed column 121 includes a base 1211 and a fixed cylinder 1212 connected in sequence, the second turbine connecting seat 134 is disposed at the bottom end of the base 1211 and is fixedly connected to the side wall of the base 1211. The second turbine 133 is rotatably connected to the second turbine connecting seat 134 through a bearing.

[0057] The second lead screw 132 extends perpendicular to the length of the support column 12, passes through the fixed column 121, and is connected to the second worm gear 133 via a drive mechanism. Specifically, the second lead screw 132 passes through the central hole of the second worm gear 133 and is connected to the central hole of the second worm gear 133 via a matching threaded structure. Both ends of the second lead screw 132 are fixedly connected to two supports 131 respectively. When the second worm gear 133 rotates, it drives the fixed column 121 to move along the second lead screw 132. Furthermore, the support device 1 also has a worm gear that drives the second worm gear 133 to rotate. The outer periphery of the second worm gear 133 meshes with the worm gear, and one end of the worm gear can be configured to pass through the side wall of the fixed column 121 and be located on the outside of the fixed column 121. The worm gear can be driven to rotate manually or by a motor.

[0058] Using the above scheme, when adjusting the position of the bottom end of the support column 12 relative to the support platform 11 in its circumferential direction, the fixed connection between the bottom end of the support column 12 (i.e., the bottom end of the fixed column 121) and the top surface of the support platform 11 is disassembled (specifically, by loosening the bolts). The second worm gear 133 is driven to rotate, causing the fixed column 121 to move along the extension direction of the second lead screw 132 and the adjusting waist hole 111 to the predetermined position. Then, the fixed connection between the bottom end of the fixed column 121 and the top surface of the support platform 11 is achieved by tightening the bolts. This embodiment uses a worm gear transmission structure to drive the support column 12 to translate along the support platform 11, and the translational fine adjustment of the support column 12 is achieved in conjunction with the adjusting waist hole 111. The operation is simple and labor-saving, and the adjustment accuracy is high.

[0059] Furthermore, two different worm gears can be used to drive the first turbine 1241 and the second turbine 133 respectively, or the same worm gear can be used to drive the first turbine 1241 and the second turbine 133. Specifically, positioning holes corresponding to the positions of the first turbine 1241 and the second turbine 133 can be provided on the side wall of the fixed column 121. As needed, the worm gear can be passed through a positioning hole to mesh with one of the first turbine 1241 and the second turbine 133, or it can be taken out of the positioning hole to mesh with the other of the first turbine 1241 and the second turbine 133.

[0060] In another specific implementation, such as Figure 4 , Figure 6 and Figure 9 As shown, a strip-shaped hole 12111 extending along the length of the fixed post 121 is provided on the side wall of the fixed post 121; one end of the worm gear 1242 passes through the strip-shaped hole 12111, and the worm gear 1242 can switch between a first adjustment position and a second adjustment position relative to the strip-shaped hole 12111; as shown Figure 6 As shown, when the worm gear 1242 is in the first adjustment position, the worm gear 1242 is connected to the first turbine 1241 for driving the lifting column 122 to rise or fall relative to the fixed column 121; as Figure 9 As shown, when the worm 1242 is in the second adjustment position, the worm 1242 is connected to the second turbine 133 for transmission, so that the rotation of the worm 1242 drives the second turbine 133 to rotate, and the linkage fixed column 121 moves along the second lead screw 132, which is used to drive the support column 12 to move relative to the support platform 11 in the circumferential direction of the support platform 11.

[0061] Specifically, the strip-shaped hole 12111 is used to guide the movement of the worm gear 1242 between the first adjustment position and the second adjustment position, specifically, as shown in the example. Figure 6 and Figure 9 As shown, the upper end of the strip hole 12111 can be set to correspond to the first turbine 1241, which is the first adjustment position; the lower end of the strip hole 12111 can be set to correspond to the second turbine 133, which is the second adjustment position; and when the worm 1242 moves to the first adjustment position or the second adjustment position, the connecting shaft seat 1244, which supports one end of the worm 1242 located outside the fixed column 121, also moves to the first adjustment position or the second adjustment position accordingly, so that one end of the worm 1242 passes through the bearing in the connecting shaft seat 1244, and the connecting shaft seat 1244 is fixedly connected to the outer wall of the fixed column 121; more specifically, as Figure 6 As shown, it can be at the upper and lower ends of the strip hole 12111 ( Figure 6 Connecting holes are provided on the side walls of the fixing posts 121 on both sides (shown at the lower end) for fixing the connecting shaft seat 1244 to the fixing posts 121 with bolts. Furthermore, the upper end of the strip-shaped hole 12111 can extend perpendicularly to the extending direction of the strip-shaped hole 12111, making the strip-shaped hole 12111 inverted L-shape, so that the worm gear 1242 can disengage from the worm gear 1242 through movement within this extended section. And, as shown... Figure 6 and Figure 9As shown, when the handwheel 1245 drives the worm gear 1242, the handwheel 1245 is also configured to move with the worm gear 1242 to the first adjustment position or the second adjustment position and be connected to one end of the worm gear 1242 for transmission. Specifically, the handwheel 1245 and one end of the worm gear 1242 can be connected by a spline, so that the handwheel 1245 and one end of the worm gear 1242 are slidably connected axially and connected for transmission in the circumferential direction. By sliding, the handwheel 1245 can be connected and separated from one end of the worm gear 1242. After the handwheel 1245 is connected to the worm gear 1242, the worm gear 1242 can be driven to rotate by rotating the handwheel 1245.

[0062] Using the above scheme, a worm gear 1242 is used to drive the bottom end of the support column 12 to move relative to the support platform 11 in its circumferential direction, and to drive the lifting column 122 to rise and fall relative to the fixed column 121 in its length direction. This makes the support device 1 simple in structure, and the drive position can be quickly switched through the strip hole 12111, making the operation simple and efficient.
