Description

Technical Field

[0001] The invention relates to the technical field of vacuum chamber upper neck tube hoisting equipment, in particular to a hoisting and adjusting tool used for assembling the upper neck tube of a fusion reactor host vacuum chamber. Background Art

[0002] Energy is one of the important issues that must be solved in the process of human development, and it is also the root cause of competition and conflict between countries at this stage. Nuclear fusion, as a new type of efficient and clean energy, is widely regarded as the ultimate solution to human energy problems. Therefore, controlled nuclear fusion is an important field that countries around the world are actively researching and exploring. Controlled nuclear fusion uses a fusion device called tokamak to magnetically confine high-temperature plasma, so that the plasma undergoes fusion reactions in a vacuum chamber, releasing huge amounts of energy, which is then converted into energy for human use. The entire tokamak device contains tens of thousands of parts, among which the double-layer shell structure of the vacuum chamber provides a high-quality vacuum environment for the plasma. A series of windows are arranged on the outside to correspond to different host equipment functions. The vacuum chamber windows are connected to external equipment through a neck tube. Therefore, the vacuum chamber neck tube is one of the important components of the tokamak device. The accurate installation of the neck tube is also an important part of the completion of the construction of the fusion device.

[0003] The upper neck tube of the vacuum chamber is located between the main vacuum chamber of the fusion reactor and the dewar cylinder. The axis of the neck tube is tilted downward and points to the geometric center of the vacuum chamber. The installation space is relatively compact. At the same time, the installation and positioning accuracy of the neck tube is required to be high to ensure the normal operation of the main equipment outside the window. In addition, after the upper neck tube of the vacuum chamber is transported and adjusted in place, it is necessary to ensure long-term stable fixed support to meet the welding requirements. Therefore, how to transport and adjust the upper neck tube of the vacuum chamber to the installation and welding position is a key step in the assembly of the neck tube.

[0004] Some existing technical solutions use lifting mechanisms to achieve the transportation, position adjustment and long-term support of the neck tube components, but the internal space of the fusion reactor host is compact and small, and the predetermined installation position of the neck tube on the vacuum chamber is far away from the support plane of the lifting mechanism, which makes it difficult to meet the technical requirements of the support stability, position adjustment accuracy and operation space for the installation of the large-mass and large-size neck tube on the vacuum chamber. In addition, some technical solutions use horizontal linear tracks to transport the neck tube of the vacuum chamber from the inside of the building along the radial direction of the host to the predetermined installation position, but this technical solution is only applicable to the installation of the neck tube in the middle of the host vacuum chamber, and it is impossible to build a transfer track for the neck tube on the host vacuum chamber with the axis tilted downward.

[0005] In traditional technology, technicians also use lifting equipment and hoists to transfer the middle neck tube into place, but the positioning accuracy of conventional lifting equipment is poor. At the same time, the steel wire ropes used by cranes and conventional hoists are all flexible connections, which cannot meet the position adjustment accuracy requirements and fixed support of the neck tube in the vacuum chamber. In addition, the neck tube in the vacuum chamber needs to be fixed and supported for a long time for welding operations. The long-term occupation of lifting equipment on site will significantly reduce the installation efficiency of the fusion reactor host. Summary of the invention

DETAILED DESCRIPTION

[0020] This specification will clearly and completely express the technical solutions in the following examples based on the drawings of the embodiments of the present invention. The implementation methods described in this specification are only some of the embodiments of the present invention, not all of them. All other embodiments extended and inspired by those skilled in the art based on these embodiments in this application without creative work should fall within the scope of protection of the present invention.

[0021] In this embodiment, a lifting and adjusting tool for assembling the upper neck tube of the vacuum chamber of a fusion reactor host is mainly used to Fig. 9 The neck tube on the vacuum chamber shown is clamped and moved, as shown Figure 1-4 As shown, its main structure includes a clamping assembly 4 for clamping the neck tube, and also includes a radial moving platform 5 and a normal moving platform 2 whose moving directions are perpendicular to each other. Specifically, the normal moving platform 2 is linearly slidably mounted on the radial moving platform 5, and the radial moving platform 5 is mounted on the ground through a number of support columns 1, thereby achieving support and force transmission for hoisting the neck tube. Figure 2 The normal moving platform 2 includes a moving plate 11 installed with linear sliding. The upper surface of the moving plate 11 is specially provided with four guide wheels in an annular array. A circular mounting plate 13 is provided in the center of the array. The cylindrical side of the mounting plate 13 needs to be in contact and cooperate with the four guide wheels in a rolling manner so as to realize the rotational installation. That is, the mounting plate 13 is located on the upper surface of the moving plate 11 in a rotationally cooperative manner. When in use, the mounting plate 13 directly serves as a bearing base component for the lifting neck pipe and the rotating neck pipe. In order to drive the mounting plate 13 to rotate, as shown in FIG. Figure 2As shown, a transmission block is provided on the upper surface near the edge thereof, and the transmission block is connected to the first hydraulic telescopic rod 15 installed on the moving plate 11, so that when the first hydraulic telescopic rod 15 is extended or retracted, the mounting plate 13 rotates counterclockwise or clockwise around its center. A vertical adjustment component 3 capable of vertical telescopic movement is also provided on the upper surface of the mounting plate 13, and the telescopic end of the vertical adjustment component 3 is connected to the top of the clamping assembly 4, thereby lifting the neck tube and moving it to the corresponding installation height position.

[0022] like Figure 3 As shown, in this embodiment, a plurality of guide rods 17 are vertically fixed to the upper surface of the mounting plate 13, and the top ends of the guide rods 17 are connected as a whole through a connecting frame 19, and a connecting arm 18 is simultaneously sleeved between two adjacent guide rods 17, and the connecting arm 18 can be a strip-shaped structure, and the two ends of the connecting arm 18 are respectively vertically slidably sleeved on the two guide rods 17 to realize sliding installation, and the middle of the connecting arm 18 and the end of the hinge column 23 fixed on the top of the clamping assembly 4 are installed in a rotationally matched structural form, so that not only can the hinge column 23 be pushed, it can be moved vertically smoothly, and the clamping assembly 4 can be pushed back and forth to rotate in the form of swinging back and forth around the hinge column 23; specifically, in practice, a pushing component 16 can be respectively provided at the front and rear ends in the length direction of the connecting arm 18, and this pushing component 16 is installed on the upper surface of the mounting plate 13 to push the clamping assembly 4 to rotate an angle around the axis of the hinge column 23, that is, to realize forward and backward swinging. In a specific implementation, the above-mentioned pushing component 16 can be directly a hydraulic rod, or it can be Figure 3 As shown, the mounting seat 20 and the adjusting screw 21 are directly used in a matching form, that is, the mounting seat 20 is fixed on the upper surface of the mounting plate 13, and the adjusting screw 21 passes through one side of the mounting seat 20 in a threaded manner and contacts with the clamping assembly 4, so that when the adjusting screw 21 is turned, the clamping assembly 4 is pushed in the corresponding direction to adjust the posture of the neck tube clamped by the clamping assembly 4.

[0023] like Figure 2As shown, the radial mobile platform 5 includes a pair of radial beams 8 arranged in parallel, as well as a slider 7, a ram 6, and a bearing plate 9, wherein the ends of the radial beams 8 are fixedly connected to the support column 1 so as to be supported, and the bearing plate 9 is arranged across the two radial beams 8. The bearing plate 9 can be a rectangular plate-like structure with a number of evenly arranged rectangular through holes inside, which can improve the bearing capacity, and each side of the bearing plate 9 is respectively installed by sliding cooperation between the slider 7 and the ram 6 to achieve linear movement. In addition, two rows of guide blocks 10 arranged opposite to each other are provided on the bearing plate 9, and the guide blocks 10 are rectangular blocks. The moving plate 11 is installed on the bearing plate 9 between the two rows of guide blocks 10, through side sliding cooperation, and in the moving direction guided by the guide blocks 10, the two sides of the moving plate 11 are respectively connected to a second hydraulic telescopic rod 12 through a fixed block to drive the moving plate 11 to move and adjust the position of the neck tube.

[0024] Specifically, if Figure 4 As a preferred design structure, the clamping assembly 4 includes a vertical beam 22 and a horizontal beam 25, both of which can be reinforced with a reinforcing rib plate 39 to strengthen the structural stability. In particular, a hinge column 23 is fixed horizontally through the top of the vertical beam 22, and the vertical beam 22 vertically passes through the corresponding through holes on the moving plate 11 and the mounting plate 13, so that the hinge column 23 is connected to the push component 16 to move vertically with the hinge column 23 and the clamping assembly 4 connected thereto, that is, to drive the hinge column 23 and the vertical beam 22 to move vertically. When installing, refer to Figure 5 The vertical beam 22 is vertically fixed on the central upper surface of the horizontal beam 25. A clamp arm 24 is installed on both sides of the lower part of the horizontal beam 25. The top ends of the two clamp arms 24 are respectively threadedly sleeved on two bevel gear shafts 26 that are rotatably installed in the horizontal beam 25. The opposite ends of the two bevel gear shafts 26 are each installed with a driven bevel gear 27. The clamp arm 24 can be a rectangular columnar structure with a horizontal threaded hole in the center of the top. The center of the two bevel gear shafts 26 is provided with a driving bevel gear 28 that meshes with them at the same time, so that when the driving bevel gear 28 rotates, the two clamp arms 24 can move closer to or away from each other along the length direction of the horizontal beam 25, so as to achieve the effect of the above-mentioned embodiment. Figure 8 The neck tube is clamped as shown and moved into position.

[0025] In addition, if Figure 5As shown, a rotating shaft 29 is rotatably installed in the vertical beam 22, and a gear column 30 is fixed at the upper end of the rotating shaft 29. The gear column 30 is a special gear structure with involute gear teeth processed along the surface of a cylindrical shaft, and a driving bevel gear 28 is fixed at the lower end of the gear column 30. A driving gear plate 31 is provided on the upper surface of the mounting plate 13. The driving gear plate 31 can rotate while moving axially, thereby driving the hinge column 23 to move vertically and always keep meshing with the gear column 30. This is why this special gear structure is adopted, and when the hinge column 23 and the vertical beam 22 reach the set height, the two clamping arms 24 just clamp the neck tube, and the clamping and positioning efficiency is higher.

[0026] like Figure 5-6 The driving gear plate 31 is fixed on a lead screw 32 which is vertically fixed on the main shaft of the driving motor 35. The driving motor 35 is installed in the base 33 through a guide block 34 in a vertical sliding manner. That is, the inner wall of the base 33 is provided with a vertical slide groove. The guide block 34 is vertically slidably installed in the slide groove, and the lead screw 32 extends upward from the base 33 in a threaded manner. When the driving motor 35 is started, the main shaft rotates with the lead screw 32. Since the lead screw 32 is threaded with the top of the base 33, the driving motor 35 will move vertically, and then the lead screw 32 will move vertically, pushing the hinged column 23 to lift the clamping assembly 4, thereby achieving the purpose of lifting the neck tube. More specifically, as Figure 6-7 As shown, a connecting column 38 is coaxially fixed to the center of the top of the driving gear plate 31, and the end of the connecting column 38 is rotatably mounted on the bottom of an outer ring sleeve 36, and the outer ring sleeve 36 is rotatably sleeved on the end of the hinge column 23, so that when the hinge column 23 can be pushed, the vertical beam 22 will not be affected from swinging back and forth around the hinge column 23. More specifically, as Figure 7 A friction ring 37 is coaxially sleeved between the outer ring sleeve 36 and the hinge column 23. The friction ring 37 contacts and cooperates with the outer ring sleeve 36 and the hinge column 23 in the form of rotational friction to prevent the outer ring sleeve 36 from easily rotating relative to the hinge column 23. In addition, the axis of the connecting column 38 passes through the center of the hinge column 23, so that the vertical lifting of the hinge column 23 is more stable and reliable.
