Description

Technical Field

[0001] This utility model relates to the field of steel pipe thermal expansion technology, and in particular to a support device for steel pipe thermal expansion that is easy to adjust. Background Technology

[0002] During hot expansion, steel pipes undergo two main steps: heating and diameter expansion. During heating, residual stress is generated inside the steel pipe due to uneven deformation and volume changes in the metal. If these stresses are not relieved promptly, the steel pipe may experience deformation and cracking during use, severely impacting its service life and performance. The main reason for the rapid cooling during hot expansion is to eliminate residual stress and improve mechanical properties.

[0003] The common cooling method is to use cooling water to quickly rinse the surface of the steel pipe during the translation process. However, this method will cause a large amount of water vapor to enter the air, affecting visibility and the monitoring of the surface condition of the steel pipe during the expansion process. Utility Model Content

[0004] This utility model discloses an easily adjustable support device for hot expansion of steel pipes, which aims to solve the technical problem that general cooling methods cause a large amount of water vapor to enter the air, affecting visibility and the monitoring of the surface condition of the steel pipe during the expansion process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easily adjustable support device for hot expansion of steel pipes includes a base and an expansion bracket. The outer wall of the top of the base is simultaneously fixedly connected to a conveying base, a heat dissipation mechanism, and a protective mechanism. The heat dissipation mechanism includes a bidirectional screw track, two sliders symmetrically meshed on the bidirectional screw track, a support frame fixedly connected to the outer wall of the top of each slider, a water tank and a back plate fixedly connected to the support frame, a flexible graphite sealing cover fixedly connected to one side of the outer wall of the back plate, a water delivery channel fixedly embedded in one side of the inner wall of the flexible graphite sealing cover, and multiple nozzles fixedly connected to one side of the inner wall of the water delivery channel.

[0007] The dehumidification mechanism includes two exhaust fans, and each exhaust fan is fixedly connected to a corresponding flexible graphite sealing cover.

[0008] A water pump is fixedly connected to the bottom inner wall of the water tank, and a water pipe is fixedly connected to the output end of the water pump. One end of the water pipe is fixedly connected to the corresponding water delivery channel. The two flexible graphite sealing covers are arranged symmetrically.

[0009] Each of the back plates has multiple extension brackets fixedly connected to its top and bottom outer walls, and the multiple extension brackets are fixedly connected to the top and bottom of the corresponding flexible graphite sealing cover.

[0010] By incorporating a heat dissipation mechanism, two sliders are driven inward by a bidirectional screw track, allowing the distance between the two sliders to adapt to the outer diameter of the steel pipe. Based on the elasticity of the flexible graphite sealing cover, it can accommodate steel pipes of different diameters. When the flexible graphite sealing cover is attached to the outside of the steel pipe, it is in a relatively sealed state. At this time, cooling water is sprayed out through multiple nozzles. The cooling water quickly forms water vapor upon contact with the high-temperature steel pipe surface, and the water vapor is extracted by an exhaust fan. This structure enables continuous cooling of the outer wall of the steel pipe, and the working environment is controllable during the cooling process. The water vapor will not obstruct the position of the steel pipe, facilitating the observation of the steel pipe during the diameter expansion process.

[0011] In a preferred embodiment, each of the exhaust fans is fixedly connected to the top outer wall of the support frame, and the dehumidification mechanism further includes a transition box, a pressure plate that is movably attached to the inner wall of the transition box, a support shaft fixedly connected to the top outer wall of the pressure plate, and a melamine-based composite material filled in the transition box.

[0012] One side of the transition box is fixedly connected to a connecting pipe two, and the opposite side of the transition box is fixedly connected to a connecting pipe one. The connecting pipe two is fixedly connected to a flexible graphite sealing cover, and the connecting pipe one is fixedly connected to an exhaust fan.

[0013] The bottom inner wall of the transition box is provided with multiple water leakage holes, and the top outer wall of the pressure plate is fixedly connected to a support shaft, and the top outer wall of the support shaft is fixedly connected to a pressing handle.

[0014] The exhaust fan has its output end facing upwards, and connecting frames are fixedly connected to the outer walls of the opposite sides of the exhaust fan. An inverted V-shaped baffle is fixedly connected to the top outer wall of the connecting frame.

[0015] By incorporating a dehumidification mechanism, water vapor passing through the melamine-based composite material can reduce light scattering and improve visibility, thereby further preventing a large amount of steam from entering the air and affecting visibility. In addition, the pressure plate allows for manual pressing of the melamine-based composite material to squeeze out the remaining moisture and allow it to leak out through the drainage holes, thus ensuring the melamine-based composite material's ability to intercept steam during long-term use.

[0016] In a preferred embodiment, the protective mechanism includes multiple protective frames and an inner protective layer fixedly attached to the inner wall of the multiple protective frames, and a base frame is fixedly connected to both sides of the multiple protective frames.

[0017] The base frame is fixedly connected to the top outer wall of the base, and the inner protective layer includes aerogel felt;

[0018] The inner wall of the aerogel felt is fixedly bonded with an aluminum foil composite film, and the outer wall of the aerogel felt is fixedly bonded with a rock wool board.

[0019] By incorporating protective mechanisms, which primarily cover high-temperature areas to protect workers, the inner protective layer isolates the high-temperature zone from the external space, providing protection while also reducing the temperature of the surrounding environment and creating a more comfortable working environment.

[0020] As described above, an easily adjustable support device for hot expansion of steel pipes includes a base and an expansion bracket. The outer wall of the top of the base is simultaneously fixedly connected to a conveying frame, a heat dissipation mechanism, and a protective mechanism. The heat dissipation mechanism includes a bidirectional screw track, two sliders symmetrically meshed on the bidirectional screw track, a support frame fixedly connected to the outer wall of the top of each slider, a water tank and a back plate fixedly connected to the support frame, a flexible graphite sealing cover fixedly connected to one side of the outer wall of the back plate, a water supply channel fixedly embedded in one side of the inner wall of the flexible graphite sealing cover, and multiple nozzles fixedly connected to one side of the inner wall of the water supply channel. The dehumidification mechanism includes two exhaust fans, each of which is fixedly connected to its corresponding flexible graphite sealing cover. The easily adjustable support device for hot expansion of steel pipes provided by this utility model has the technical effect of achieving continuous cooling of the outer wall of the steel pipe, and the water vapor will not obstruct the position of the steel pipe during the cooling process, facilitating the observation of the steel pipe during the expansion process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The present invention discloses an easily adjustable support device for hot expansion of steel pipes, which is mainly used in the scenario of hot expansion of steel pipes.

[0028] Reference Figures 1-3 An adjustable support device for hot expansion of steel pipe includes a base 1 and an expansion bracket 6. The outer wall of the top of the base 1 is simultaneously fixedly connected to a conveying base 5, a heat dissipation mechanism 2 and a protective mechanism 4. The heat dissipation mechanism 2 includes a bidirectional screw track 201, two sliders 202 symmetrically meshed on the bidirectional screw track 201, a support frame 204 fixedly connected to the outer wall of the top of each slider 202, a water tank 203 and a back plate 205 fixedly connected to the support frame 204, a flexible graphite sealing cover 208 fixedly connected to one side of the outer wall of the back plate 205, a water delivery channel 209 fixedly embedded in one side of the inner wall of the flexible graphite sealing cover 208, and multiple nozzles 207 fixedly connected to one side of the inner wall of the water delivery channel 209.

[0029] The dehumidification mechanism 3 includes two exhaust fans 303, each of which is fixedly connected to a corresponding flexible graphite sealing cover 208. The conveying base 5 supports the steel pipe, and during the expansion process, the steel pipe is moved forward by the front guide mechanism. Before the movement, the two sliders 202 are moved inward by the bidirectional screw track 201, so that the distance between the two sliders 202 is adapted to the outer diameter of the steel pipe. Based on the elasticity of the flexible graphite sealing cover 208, it can fit the outer surface of steel pipes of different diameters to cooperate with the bidirectional screw track 208. The screw track 201 is driven to adapt to steel pipes of different diameters. When the flexible graphite sealing cover 208 is attached to the outside of the steel pipe, it is in a relatively sealed state. At this time, cooling water is supplied through the water tank 203 and sprayed out through multiple nozzles 207. The cooling water comes into contact with the high temperature surface of the steel pipe and quickly forms water vapor. The water vapor is then extracted by the exhaust fan 303. Under this structure, the outer wall of the steel pipe can be continuously cooled, and the working environment is controllable during the cooling process. The water vapor will not obstruct the position of the steel pipe, making it convenient to observe the steel pipe during the diameter expansion process.

[0030] Reference Figure 2 In a preferred embodiment, a water pump is fixedly connected to the inner wall of the bottom end of the water tank 203, and the output end of the water pump is fixedly connected to a water pipe 210. One end of the water pipe 210 is fixedly connected to a corresponding water delivery channel 209, and two flexible graphite sealing covers 208 are symmetrically arranged.

[0031] Reference Figure 2 In a preferred embodiment, each backplate 205 has a plurality of extension brackets 206 fixedly connected to the top and bottom outer walls, and the plurality of extension brackets 206 are fixedly connected to the top and bottom of the corresponding flexible graphite sealing cover 208.

[0032] Reference Figure 3 In a preferred embodiment, each exhaust fan 303 is fixedly connected to the top outer wall of the support frame 204. The dehumidification mechanism 3 also includes a transition box 308, a pressure plate 309 that is movably attached to the inner wall of the transition box 308, a support shaft 310 fixedly connected to the top outer wall of the pressure plate 309, and a melamine-based composite material 305 filled in the transition box 308.

[0033] Reference Figure 3 In a preferred embodiment, a second connecting pipe 307 is fixedly connected to one inner wall of the transition box 308, and a first connecting pipe 304 is fixedly connected to the opposite inner wall of the transition box 308. The second connecting pipe 307 is fixedly connected to the flexible graphite sealing cover 208, and the first connecting pipe 304 is fixedly connected to the exhaust fan 303.

[0034] Reference Figure 3In a preferred embodiment, the bottom inner wall of the transition box 308 is provided with a plurality of drainage holes 306, the top outer wall of the pressure plate 309 is fixedly connected to a support shaft 310, and the top outer wall of the support shaft 310 is fixedly connected to a pressing handle 311.

[0035] Reference Figure 3 In a preferred embodiment, the output end of the exhaust fan 303 faces upward, and connecting frames 302 are fixedly connected to the outer walls of the opposite sides of the exhaust fan 303. An inverted V-shaped baffle 301 is fixedly connected to the top outer wall of the connecting frame 302. When water vapor is drawn out by the exhaust fan 303, the water vapor passes through the melamine-based composite material 305. By combining the hydrophilic gel and the high specific surface area skeleton, the water vapor is effectively intercepted from entering the air, thereby reducing the light scattering of the water vapor and improving visibility. This further prevents a large amount of steam from entering the air and affecting visibility. In addition, by setting the pressure plate 309, the pressure plate 309 can be pressed by manually pressing the pressing handle 311 to squeeze out the water stored in the melamine-based composite material 305 and let it leak out through the drain hole 306. This ensures the interception of steam by the melamine-based composite material 305 during long-term use. At the same time, by setting the inverted V-shaped baffle 301, some of the discharged steam is prevented from shining directly upward, and visibility is further ensured by dispersing the steam.

[0036] Reference Figure 1 In a preferred embodiment, the protective mechanism 4 includes a plurality of protective frames 401 and an inner protective layer 402 fixedly attached to the inner wall of the plurality of protective frames 401. A base frame 403 is fixedly connected to both sides of the plurality of protective frames 401.

[0037] Reference Figure 1 and Figure 4 In a preferred embodiment, the base frame 403 is fixedly connected to the top outer wall of the base 1, and the inner protective layer 402 includes an aerogel felt 405.

[0038] Reference Figure 4 In a preferred embodiment, an aluminum foil composite film 406 is fixedly attached to the inner wall of the aerogel felt 405, and a rock wool board 404 is fixedly attached to the outer wall of the aerogel felt 405. The protective mechanism 4 mainly covers the high-temperature position to protect the workers from touching the high-temperature outer wall of the steel pipe. The inner protective layer 402 reflects radiant heat through the aluminum foil composite film 406 on the inner side and establishes a heat barrier based on the excellent heat insulation effect of the aerogel felt 405. The stability of the inner protective layer 402 is maintained by the stability of the rock wool board 404, while providing a certain heat insulation effect. This isolates the high-temperature area from the external space, reduces the temperature of the surrounding environment while providing protection, and provides a more comfortable working environment.

[0039] Working principle: The conveyor base 5 supports the steel pipe, and during the expansion process, the steel pipe is moved forward by the front guide mechanism. Before moving, the two sliders 202 are driven inward by the bidirectional screw track 201, so that the distance between the two sliders 202 is adapted to the outer diameter of the steel pipe. Based on the elasticity of the flexible graphite sealing cover 208, it can fit the outer surface of steel pipes of different diameters to cooperate with the drive of the bidirectional screw track 201 and adapt to the use of steel pipes of different diameters. When the flexible graphite sealing cover 208 is fitted to the outside of the steel pipe, it is in a relatively sealed state. At this time, cooling water is supplied by the water tank 203 and sprayed out through multiple nozzles 207. The cooling water comes into contact with the high temperature steel pipe surface and quickly forms water vapor, which is then extracted by the exhaust fan 303. Under this structure, the outer wall of the steel pipe can be continuously cooled, and the working environment is controllable during the cooling process. The water vapor will not obstruct the position of the steel pipe, which is convenient for observing the steel pipe during the expansion process.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
