Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically a pier support structure that can release the temperature stress of steel pipes. Background Technology

[0002] In long-distance pipeline projects, the anchor block, as the core component for constraining the displacement of the steel pipe, directly affects the release effect of temperature stress through its connection method with the pipeline and the design of its auxiliary structures.

[0003] In terms of sealing and sliding compensation, traditional designs have significant shortcomings: sealing components are mostly single rubber rings, which are prone to aging and failure under high temperature and pressure and lack axial compensation capabilities; the lateral constraint inner wall and the steel pipe are mostly in direct metal-to-metal contact, resulting in high friction and easy corrosion, which restricts the free expansion and contraction of the steel pipe; the material selection is unreasonable, carbon steel lateral constraint components are prone to corrosion, and nitrile rubber seals have a narrow temperature resistance range, making them difficult to adapt to actual use environments.

[0004] Therefore, this utility model provides a pier support structure that can release the temperature stress of steel pipes. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a pier support structure that can release the temperature stress of steel pipes is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A pier support structure for releasing temperature stress in steel pipes, comprising a base plate; a pier is fixedly installed on the top of the base plate, and support mechanisms are provided on both sides of the pier; a sealing component is provided on the inner wall of the support mechanism; a movable component is provided on the inner wall of the pier; a telescopic component is provided on the side of the connecting pipe near the movable component; the support mechanism includes a fixed long plate, a connecting plate, a nut, and a bracket; the fixed long plate is fixedly installed on both sides of the pier, and the connecting plate is threadedly installed on the top of the fixed long plate by a nut; the top of the connecting plate is fixedly installed with the bracket; the cooperation of the fixed long plate, connecting plate, nut, and bracket enables the bracket to have a detachable function, thus making maintenance more convenient and reducing maintenance difficulty after use.

[0007] Preferably, the sealing assembly includes a sealing ring and a connecting pipe. The sealing ring is fixedly installed on the inner wall of the bracket, and the inner wall of the sealing ring is slidably installed with the connecting pipe. In this scheme, the cooperation between the sealing ring and the connecting pipe can facilitate the user to connect the steel pipe. At the same time, the sliding connection between the sealing ring and the connecting pipe can also enable the steel pipe to have a movable function.

[0008] Preferably, the movable component includes a bearing and a connecting pipe. The bearing is fixedly installed in the middle of the inner wall of the pier, and the inner ring of the bearing is fixedly installed with the connecting pipe. In this scheme, the cooperation between the bearing and the connecting pipe allows the connecting pipe to rotate freely within the bearing, so as to achieve flexible adjustment to cope with different usage environments.

[0009] Preferably, the telescopic component includes a flexible tube and a connecting ring. The flexible tube is fixedly installed at both ends of the connecting tube, and the side of the flexible tube away from the connecting tube is fixedly installed with the connecting ring. The connecting ring is threadedly connected to the connecting tube. In this solution, the flexible tube and the connecting ring work together to connect the connecting tube and the connecting tube, and at the same time, the connecting tube can have a telescopic function through its own deformation, so as to achieve the effect of stress relief.

[0010] Preferably, the flexible tube is made of fluororubber. In this design, fluororubber has extremely strong chemical corrosion resistance (resistant to strong acids, strong alkalis, organic solvents, etc.) and a wide temperature range of -20℃ to over 200℃, which can better accommodate the connecting tube and the connecting pipe.

[0011] Preferably, the docking plate and the bracket are made of fiberglass. In this design, fiberglass is a composite of glass fiber and resin, which is lightweight (about 1 / 4 the weight of steel), corrosion resistant (resistant to acids, alkalis, and salt spray), and has good insulation properties.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The pier support structure of this utility model that can release the temperature stress of steel pipes, through the setting of fixed long plates, butt plates, nuts, brackets, sealing rings and connecting pipes, enables the bracket to be detachable by the cooperation of fixed long plates, butt plates, nuts and brackets, so that maintenance is more convenient after use and the maintenance difficulty is reduced. The cooperation of sealing rings and connecting pipes makes it easy for users to connect steel pipes. At the same time, the sliding connection between sealing rings and connecting pipes also enables the steel pipes to move.

[0014] 2. The pier support structure of this utility model that can release the temperature stress of steel pipes, through the arrangement of bearings, connecting pipes, flexible pipes and connecting rings, allows the connecting pipes to rotate freely within the bearings, so as to achieve flexible adjustment to cope with different usage environments. The flexible pipes and connecting rings can connect the connecting pipes to the connecting pipes, and at the same time, the connecting pipes can have the function of expansion and contraction through their own deformation, so as to achieve the effect of releasing stress.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a pier support structure capable of releasing temperature stress in steel pipes includes a base plate 1; a pier 2 is fixedly installed on the top of the base plate 1, and support mechanisms 3 are provided on both sides of the pier 2.

The fixed long plate 31 is fixedly installed on both sides of the pier 2, and the connecting plate 32 is threadedly installed on the top of the fixed long plate 31 by the nut 33. The top of the connecting plate 32 is fixedly installed with the bracket 34; The sealing component 4 includes a sealing ring 41 and a connecting pipe 42. The sealing ring 41 is fixedly installed on the inner wall of the bracket 34, and the inner wall of the sealing ring 41 is slidably installed with the connecting pipe 42. The movable component 5 includes a bearing 51 and a connecting pipe 52. The bearing 51 is fixedly installed in the middle of the inner wall of the pier 2, and the inner ring of the bearing 51 is fixedly installed with the connecting pipe 52. The telescopic component 6 includes a flexible pipe 61 and a connecting ring 62. The flexible pipe 61 is fixedly installed at both ends of the connecting pipe 52, and the side of the flexible pipe 61 away from the connecting pipe 52 is fixedly installed with the connecting ring 62. The connecting ring 62 is threadedly connected to the connecting pipe 42. The flexible pipe 61 is made of fluororubber, and the docking plate 32 and the bracket 34 are made of fiberglass.

[0026] like Figures 1 to 5 As shown, the cooperation of the fixed plate 31, the mating plate 32, the nut 33, and the bracket 34 enables the bracket 34 to be detachable, making maintenance more convenient and reducing maintenance difficulty after use. The cooperation of the sealing ring 41 and the connecting pipe 42 allows the user to easily connect the steel pipe. At the same time, the sliding connection between the sealing ring 41 and the connecting pipe 42 also enables the steel pipe to move. The cooperation of the bearing 51 and the connecting pipe 52 allows the connecting pipe 52 to rotate freely within the bearing 51, achieving flexible adjustment to cope with different... In the same usage environment, the flexible tube 61 and the connecting ring 62 can be used together to connect the connecting tube 42 and the connecting tube 52.

Meanwhile, the bearing 51 allows the connecting pipe 52 to rotate freely during use, thereby improving the flexibility and lightness of the steel pipe. During use, high temperature will accumulate on the inner wall of the pier 2. Due to the opening of the vent hole 70, the high temperature inside the pier 2 can be smoothly discharged to achieve temperature release.
