Referring to fig. 1-3, an embodiment of the present application provides a GIL pipe flexible supporting device, including a flexible support 100; the flexible stent 100 comprises an outer frame 110 and four restraining cords 120; the outer frame 110 is sleeved on the periphery of the GIL pipe 200; the periphery of the GIL pipe 200 is provided with connecting rings 130 corresponding to the four restraining ropes 120 one to one; the four connection rings 130 are respectively disposed in four different angular directions of the GIL pipe 200; the four restraint ropes 120 are respectively arranged through the corresponding connecting rings 130, and two ends of the four restraint ropes 120 are connected with the outer frame 110; the four restraint ropes 120 are all installed inside the outer frame 110 in an arc shape, and the convex edge of each restraint rope 120 faces the GIL pipe 200; of the four constraining ropes 120, the constraining rope 121 positioned uppermost has the largest radius of curvature, and the constraining rope 123 positioned lowermost has the smallest radius of curvature.
More specifically, the four connection rings 130 are preferably distributed in four directions of the GIL pipe 200 at intervals of 90 °, respectively, so that the connection rings 130 installed have the best vibration isolation effect on the GIL pipe 200; the outer frame 110 is annular, and the arrangement of the four restraint ropes 120 can prevent the whole flexible support 100 from being separated from the GIL pipe 200; the convex edge of each restraining rope 120 faces the GIL pipe 200, that is, the direction of the connection line between the center point of the arc formed by each restraining rope 120 and the center of the circle where the arc is located is the direction far away from the GIL pipe 200. The uppermost constraining rope 121 bears the main vertical load of the GIL pipe 200, so that the uppermost constraining rope 120 has the largest radius of curvature and the largest vertical equivalent stiffness; the curvature radius of the restraining ropes 122 at both sides is smaller than that of the restraining rope 121 at the uppermost side, and the curvature radius of the restraining ropes 122 at both sides is larger than that of the restraining rope 123 at the lowermost side, for preventing the GIL pipe 200 from being excessively displaced in the horizontal direction; the radius of curvature of the lowermost restraint rope 123 is small to provide vertical frictional damping for the GIL pipe 200.
This embodiment is when using, four about ropes 120 can form the vibration isolation protection to the GIL pipeline 200 that is located the centre jointly, and can be to GIL pipeline 200 along vertically, horizontal and vertical three direction play the vibration isolation guard action, have the damping power consumption effect, play the effect that reduces the local settlement influence, be favorable to reducing the influence of external vibration to GIL pipeline 200, solve the technical problem that current GIL pipeline 200 support can't deal with the horizontal deformation and the vertical deformation of GIL pipeline 200 effectively, still have from the reset ability simultaneously, satisfy the installation demand of GIL pipeline 200.
Further, in the present embodiment, the outer frame 110 is specifically a square frame; the four restraint ropes 120 are respectively distributed at positions corresponding to the four sides of the square frame. Compared with a circular frame or other frames, the square frame has a more appropriate empty space inside to allow the four restraint ropes 120 to be connected and fixed with the GIL pipeline 200 in an arc shape, and during installation, the restraint ropes 120 have prestress, so that the whole structure is more stable.
More specifically, the height of the square frame in the vertical direction is smaller than the width of the square frame in the horizontal direction, so that the arrangement is more convenient for distributing four restraint ropes 120 with different curvatures on the square frame.
Further, in the present embodiment, two ends of the uppermost constraining rope 121 of the four constraining ropes 120 are respectively connected to two parallel sides of the square frame, and two ends of the remaining constraining ropes 120 are connected to corresponding sides of the square frame. That is, one end of the constraint rope 121 positioned at the uppermost position is connected with the left side of the square frame, and the other end is connected with the right side of the square frame; two ends of a left restraint rope in the restraint ropes 122 on the two sides are connected with the left side of the square frame, and two ends of a right restraint rope are connected with the right side of the square frame; both ends of the constraint rope 123 positioned at the lowest part are connected with the bottom edge of the square frame, so that the installation requirement that the curvature radius of the constraint rope 121 positioned at the highest part is the largest can be met.
Further, in the present embodiment, two ends of the uppermost constraining rope 121 of the four constraining ropes 120 are respectively abutted against the two constraining ropes 120 located at the two sides of the outer frame 110. This arrangement can suitably improve the bearing capacity of the uppermost restraint cord 121, and does not affect the deformation and vibration isolation of the restraint cords 122 on both sides because there is a gap between the restraint cords 122 on both sides and the lowermost restraint cord 123.
Further, in the present embodiment, the two restraining ropes 122 located at both sides of the outer frame 110 are symmetrically disposed. The restraint ropes 122 disposed at both sides in this way can provide an optimal vibration isolation protection effect to the GIL pipe 200 in the lateral direction.
Further, in the present embodiment, the number of the flexible stents 100 is plural, and the plurality of flexible stents 100 are uniformly distributed along the length direction of the GIL pipe 200. The arrangement can ensure that the whole GIL pipeline 200 has good vibration isolation protection effect at all places, and the influence of external vibration on the GIL pipeline 200 is greatly reduced.
Further, in the present embodiment, the distance between two adjacent flexible supports 100 is 10m to 15 m. By arranging the flexible support 100 on the GIL pipe 200 at an appropriate distance, the cost required for vibration isolation of the GIL pipe 200 can be effectively reduced without affecting the good vibration isolation effect on the GIL pipe 200.
Further, in the present embodiment, both ends of each restraint cord 120 are adjustably connected to the outer frame 110 through the fixing adjusters 140. The length of each restraint rope 120 in the outer frame 110 can be adjusted according to actual requirements through the fixed adjuster 140, so that the four restraint ropes 120 are suitable for vibration isolation protection of GIL pipelines 200 with different sizes, and the application range of the whole device is greatly enlarged.
Further, in the present embodiment, each of the restraining ropes 120 is formed by winding a plurality of steel wire ropes. The restraining rope 120 made of steel wire rope is not only low in cost and convenient to install, but also made of stainless steel and good in durability.
Further, in the present embodiment, the relationship between the stiffness of each connection ring 130 and the curvature radius and arc length angle of the corresponding restraint cord 120 is as follows:
where k is stiffness of the connection ring 130, R is a radius of curvature of the constraining rope 120, θ is an arc length angle of the constraining rope 120, EI is bending stiffness of the steel wire rope, E is steel wire rope elastic modulus strength constituting the constraining rope 120, and d is a total diameter of the multi-strand steel wire rope constituting the constraining rope 120.
Referring to fig. 2, the arc length angle of the constraining rope 120, i.e. the central angle of the arc where it is located, is the stiffness of the connecting ring 130 along the direction a; when the rigidity required by the GIL pipe 200 at the connecting ring 130 is known through multiple tests, the bending rigidity of the steel wire rope can be calculated through measurable values, so that the constraint conditions between the curvature radius of the constraint rope 120 required by the connecting ring 130 and the arc length angle of the constraint rope 120 can be inversely calculated through the formula, and a worker can adjust the length of the constraint rope 120 in the outer frame 110 according to actual conditions.
