[0002] In the construction of pipeline projects in the fields of water conservancy projects, water supply systems, and petrochemicals, steel pipes, as an important medium transportation material, their stability and durability are of vital significance to ensuring the safe and efficient operation of the system.

[0003] Steel pipes are prone to deformation due to their own weight. The larger the diameter and the greater the weight of the steel pipe, the lower the rigidity of the steel pipe. The steel pipe is more likely to deform during manufacturing, storage, transportation, installation and use. The traditional method of preventing deformation is to weld a cross or M-shaped angle steel support frame inside the steel pipe to prevent deformation of the steel pipe.

[0004] However, the support frame in this method is difficult to install, time-consuming and labor-intensive, and is cumbersome to use and disassemble. After dismantling, it will cause waste of materials and cannot be reused. A set of anti-deformation devices can only be used for steel pipes of one specification, and the scope of application is small. A large number of anti-deformation devices not only consume a large amount of materials, but also occupy more space. Utility Model Content

[0048] See also Figure 1 , Figure 2 An anti-deformation internal support device for a steel pipe provided in an embodiment of the present application includes a center rod 1 and at least two support assemblies 2 arranged at axial intervals along the center rod 1; the support assembly 2 includes a support seat 21 connected to the center rod 1 and at least two length-adjustable support rods 22 evenly distributed along the circumference of the center rod 1, one end of the support rod 22 is detachably connected to the support seat 21, and the other end of the support rod 22 extends outward radially along the center rod 1.

[0049] See also Figure 1 , Figure 2 The anti-deformation inner support device for steel pipes provided in the embodiment of the present application is used to support the steel pipe to prevent the steel pipe from deforming during manufacturing, storage, transportation, installation and use. The installation process of the device is: first adjust the length of all support rods 22 to the shortest, then place the entire device in the steel pipe, and then control all support rods 22 to extend until the ends of the support rods 22 are tightly against the inner surface of the steel pipe. The removal process of the device is: first adjust the length of all support rods 22 to the shortest, and then take the entire device out of the steel pipe.

[0050] The anti-deformation internal support device for steel pipes provided in the embodiment of the present application is used to support different positions inside the steel pipe to prevent deformation of the steel pipe by setting at least two support components 2; by setting a central rod 1 for connecting at least two support components 2 together, the stability and rigidity of the entire device can be improved, thereby more effectively bearing and dispersing the force; compared with the prior art, the installation difficulty of the present application is small, it can be used for steel pipes of various specifications, has a wide range of applications, strong versatility, can be reused after dismantling, and occupies little space.

[0051] In some embodiments, see Figure 1 , Figure 2 The end of the support rod 22 away from the center rod 1 is connected to a buffer assembly 23. When in use, after the support rod 22 is extended, the support rod 22 can be pressed against the inner surface of the steel pipe through the buffer assembly 23, thereby reducing direct damage to the inner surface of the steel pipe. In particular, for steel pipes with anti-corrosion structures on the inner surface, when the above device is used to support the steel pipe, damage to the anti-corrosion structure on the inner surface of the steel pipe can be prevented.

[0052] The buffer assembly 23 can be a rubber pad connected to the end of the support rod 22. In some embodiments, see Figure 3 The buffer assembly 23 includes a steel pad 231, a wooden pad 232 and a rubber pad 233 which are sequentially connected from the inside to the outside along the radial direction of the center rod 1, and the steel pad 231 is connected to the support rod 22. Exemplarily, the steel pad 231 is perpendicular to the support rod 22 and the two are welded together; the steel pad 231, the wooden pad 232 and the rubber pad 233 can be bonded together or connected by fasteners such as bolts. The buffer assembly 23 can increase its contact area with the inner surface of the steel pipe and reduce the pressure per unit area.

[0053] The support base 21 can be connected to the central rod 1 by bolts or welding. Figure 1 The support seat 21 is movably connected to the central rod 1 and can move along the central rod 1. This structure can adjust the position of each support assembly 2 on the central rod 1, and then support the steel pipe at different positions in the steel pipe as needed, thereby improving flexibility during use.

[0054] The support seat 21 can be a slider that is slidably connected to the center rod 1. Figure 4The support seat 21 includes a sliding ring 211 slidably mounted on the center rod 1, and a coaxially arranged support ring 212 is provided outside the sliding ring 211. A plurality of connecting plates 213 are connected between the sliding ring 211 and the support ring 212, and one end of the support rod 22 is detachably connected to the support ring 212. Exemplarily, the inner diameter of the sliding ring 211 is adapted to the outer diameter of the center rod 1. When the sliding ring 211 is mounted on the center rod 1, the sliding ring 211 can slide along the center rod 1; the inner diameter of the support ring 212 is larger than the outer diameter of the sliding ring 211, and the support ring 212 is coaxially arranged with the sliding ring 211, and the two are fixedly connected by a plurality of connecting plates 213. For example, the connecting plates 213 include eight evenly distributed along the circumference of the support ring 212. By detachably connecting the support rod 22 and the support ring 212, it is convenient to disassemble the two after use, thereby reducing the floor space occupied by the entire device when stored.

[0055] The support rod 22 can be detachably connected to the support ring 212 by a threaded structure or a bolt. Figure 4 The support seat 21 further includes at least two fixing rods 214 evenly distributed along the circumference of the support ring 212, one end of the fixing rod 214 is connected to the outer surface of the support ring 212, and the other end of the fixing rod 214 extends radially outwardly along the support ring 212, and the support rods 22 are detachably connected to the fixing rods 214. Exemplarily, the number of the fixing rods 214 is consistent with the number of the support rods 22 and corresponds one to one, and the support rods 22 can be detachably connected to the fixing rods 214 through a threaded structure or a bolt.

[0056] The support rod 22 can adopt an existing multi-stage telescopic structure, which can be an electric structure or a manual structure. Figure 5 The support rod 22 includes an adjustment tube 221 and an adjustment screw rod 222. One end of the adjustment tube 221 is sleeved on the fixed rod 214, and the other end of the adjustment tube 221 is threadedly connected to the adjustment screw rod 222. For example, see Figure 5 The inner diameter of the adjusting tube 221 is slightly larger than the outer diameter of the fixing rod 214, so that the adjusting tube 221 can be easily sleeved on the fixing rod 214. The inner hole at the lower end of the adjusting tube 221 has an inner thread section, and the outer surface of the adjusting screw rod 222 is provided with an outer thread section. The upper end of the adjusting screw rod 222 is threadedly connected to the inner hole at the lower end of the adjusting tube 221, and the lower end of the adjusting screw rod 222 is fixedly connected to the steel pad 231 in the buffer assembly 23. When in use, refer to Figure 2 , Figure 6 After the entire device is placed in the steel pipe, one end of the control tube 221 is controlled to contact the support ring 212, and the adjusting screw 222 is first rotated to drive the buffer assembly 23 to contact the inner surface of the steel pipe, and then the adjusting tube 221 is rotated to drive the adjusting screw 222 to move toward the inner surface of the steel pipe, thereby pressing the buffer assembly 23 against the inner surface of the steel pipe.

[0057] In some embodiments, see Figure 4 , Figure 5 The fixing rod 214 is connected with a thrust bearing 215, and the end of the adjusting tube 221 abuts against the dynamic thrust assembly of the thrust bearing 215. The thrust bearing 215 is provided to bear the axial load from the adjusting tube 221, and at the same time, during the rotation of the adjusting tube 221, the friction resistance can be reduced, and the adjusting tube 221 is prevented from directly contacting with the supporting ring 212 and causing wear, thereby increasing the service life of each component.

[0058] In some embodiments, see Figure 5 An operating rod 223 is connected to the outer surface of the adjusting tube 221. When in use, a worker can directly hold the operating rod 223 to control the rotation of the adjusting tube 221, thereby improving the convenience of operation.

[0059] The center rod 1 can be a unitary structure. Figure 6 The center rod 1 includes at least two coaxially arranged standard sections 11, and two adjacent standard sections 11 are detachably connected. By arranging the center rod 1 to be spliced ​​by at least two standard sections 11, the center rod 1 can be manufactured and assembled in sections in a factory or on site, which is convenient for transportation and installation; the center rod 1 can be spliced ​​into different lengths according to actual needs to meet the requirements of steel pipes of different lengths.

[0060] Two adjacent standard segments 11 can be detachably connected by fasteners such as threaded structures and bolts. Figure 6 The standard section 11 is made of steel pipe, and two adjacent standard sections 11 are connected by a connecting rod 12, wherein the connecting rod 12 includes a cylindrical limiting portion and connecting portions fixed at both ends of the limiting portion, the outer diameter of the limiting portion is equal to the outer diameter of the standard section 11, and the connecting portion is threadedly connected to the inner hole of the standard section 11.

[0061] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiments shall still fall within the protection scope of the technical solution of the present application.
