Description
Technical Field
[0001] This invention relates to the field of transfer device technology, specifically a pipe transfer device with anti-shaking function. Background Technology
[0002] Pipe fittings require quenching and cooling processes during production, while the transfer device is mainly used to meet the automated transfer needs of pipe fittings (such as pipes, pipe fittings, etc.) in production, warehousing, and transportation, reducing manual handling losses and safety risks. It is especially suitable for the full-process automated management of pipe fittings with large length-to-diameter ratios and easy to be bumped, and is a key infrastructure connecting the entire pipeline production chain.
[0003] The transfer device is used to transport large pipes and perform quenching processes on them. The quenching process requires heating the pipes first, which requires the internal components to be resistant to high temperatures. If the moving speed is too fast during transportation, its own weight can easily cause shaking or displacement, damaging the fixing components. However, the moving speed cannot be too slow, otherwise it will affect the subsequent cooling process, causing uneven heating of the pipes and damaging them. Summary of the Invention
[0004] The purpose of this invention is to provide a pipe transfer device with anti-shaking function to solve the problems raised in the prior art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: The transfer device includes a transport component, a bottom fixing component, a top fixing component, and a pressure-bearing component. The bottom fixing component is located on the upper surface of the transport component, and the pressure-bearing component is located inside the bottom fixing component. The pressure-bearing component is used to fix the pipe fittings. The bottom of the bottom fixing component is provided with a drive component, which is used to control the rotation of the bottom fixing component. The transport component includes a track and a movable platform. The track is located on a horizontal ground, and the movable platform is located on the track. The movable platform is slidably connected to the track. A groove is opened on the upper surface of the movable platform, and a gear groove is opened in the groove. The two sides of the movable platform are slidably engaged with the track. A rack is provided on one side of the track, and the rack is located on the side of the track close to the movable platform.
[0006] Furthermore, the transfer device is used to transport large pipe fittings and quench them. The pipe fittings are about 12 meters long and weigh 4 to 6 tons. If the movement speed is too fast during transportation, their own weight can easily cause them to shake or shift, damaging the fixing components. The pipe fittings need to be rotated during quenching. Therefore, the base not only needs to fix the bottom end of the pipe fittings, but also needs to drive them to rotate. Moreover, the internal components need to be resistant to high temperatures. Among them, the transport component drives the pipe fittings to move, the bottom fixing component fixes the bottom end, the top fixing component stabilizes the top end, the pressure component fixes the bottom end when the pipe fittings are placed, and the drive component controls the rotation of the bottom fixing component. The two sides of the moving platform are connected to the rails through connectors and slide together. There are two rails in total, and each side is equipped with a rack.
[0007] The bottom fixing assembly includes a rotating cylinder, a limiting post, and a threaded rod. The rotating cylinder is located in a groove and is rotatably connected to the bottom end of the inner wall of the groove. The limiting post is located inside the rotating cylinder and is fixedly connected to the bottom end of the inner wall of the rotating cylinder. A circular groove is opened in the limiting post, and a threaded rod is provided in the circular groove. The threaded rod is rotatably connected to the inner wall of the circular groove. A secondary rotating block is sleeved on the body of the threaded rod and is fixedly connected to the threaded rod. A main rotating block is sleeved on the bottom end of the threaded rod and is threadedly engaged with the threaded rod.
[0008] Furthermore, the limiting post in the bottom fixing assembly matches the inner hole at the bottom of the pipe fitting. The diameter of the limiting post is smaller than the diameter of the pipe fitting. The limiting post is located inside the rotating cylinder. The gap between the inner wall of the rotating cylinder and the limiting post is used to place the pipe. A groove space is opened at the top of the limiting post to place the threaded rod. The upper and lower ends of the threaded rod are rotatably connected to the upper and lower ends of the inner wall of the groove. A secondary rotating block is sleeved in the middle of the threaded rod body. The secondary rotating block is driven to rotate by the threaded rod. A main rotating block is sleeved at the bottom of the threaded rod. The main rotating block is used to control the rotation of the threaded rod. When the main rotating block moves up and down, it will drive the threaded rod to rotate. The rotation of the threaded rod will drive the secondary rotating block to rotate.
[0009] The upper surface of the auxiliary rotating block is provided with a rotating rod. One end of the rotating rod is rotatably connected to the upper surface of the auxiliary rotating block, and the other end of the rotating rod is rotatably connected to the limiting block. A sliding groove is provided in the limiting column, and the sliding groove is connected to the circular groove. The limiting block is slidably connected to the sliding groove.
[0010] Furthermore, when the main rotating block moves downward, the rotation of the threaded rod will drive the secondary rotating block to rotate. The secondary rotating block will drive one end of the rotating rod to move, thereby pushing the limit block to move at the other end of the rotating rod. Since the limit block is slidably connected to the slide groove, the limit block will only move axially along the slide groove. As a result, when the rotating rod pushes the limit block, the limit block will move away from the central axis of the limit post. Conversely, when the main rotating block moves upward, the rotating rod will drive the limit block to move towards the central axis of the limit post. The final effect is that when the pipe is placed in the rotating drum, the main rotating block moves downward, and the limit block moves outward to contact the inner wall of the pipe, fixing the inner wall of the pipe and thus fixing the bottom of the pipe. When the pipe is transferred, the main rotating block moves upward, and the limit block moves inward, releasing the fixation on the inner wall of the pipe.
[0011] The pressure-bearing component includes a sliding block and a bottom block. The sliding block is slidably connected to the limiting post. A first connecting rod is provided on one side of the sliding block. One end of the first connecting rod is fixedly connected to the sliding block, and the other end of the first connecting rod is fixedly connected to the main rotating block. The bottom block is located at the bottom of the limiting post and is fixedly connected to the limiting post. A through groove is provided in the sliding block, and a first spring is provided between the sliding block and the bottom block.
[0012] Furthermore, the pressure-bearing component contacts the bottom surface of the pipe fitting and moves under the pressure of the pipe fitting's weight. The sliding block is located between the limiting post and the rotating cylinder, and the sliding block is slidably connected to the outer wall of the limiting post. The sliding block is also connected to the main rotating block through the first connecting rod. When the top of the sliding block moves downward under the pressure of the pipe fitting, it will drive the first connecting rod to move downward. The first connecting rod will drive the main rotating block to move. However, due to the restriction of the first connecting rod, the main rotating block will not rotate, and only the threaded rod will rotate. Finally, the bottom of the downward-moving sliding block will contact the top of the bottom block. The first spring between the sliding block and the bottom block is used to keep the sliding block and the bottom block in a normally separated state.
[0013] The drive assembly includes a bin, a top cover, a gear ring, and a rotating motor. A cavity is opened inside the limiting post, and the bin is located inside the cavity. The bottom end of the bin is fixedly connected to the cavity. The top cover is slidably connected to the bin. A second connecting rod is provided on one side of the top cover. One end of the second connecting rod is fixedly connected to the top cover, and the other end of the second connecting rod is fixedly connected to the gear ring. The gear ring meshes with the edge of the rack. The bin is used to store iron blocks. The fixed end of the rotating motor is fixedly connected to the bottom end of the moving platform, and the output end of the rotating motor is fixedly connected to the bottom end of the rotating drum.
[0014] Furthermore, its drive assembly is used to control the movement of the transport assembly. The cavity is used to house the bin and the top cover, and provides space for the top cover to move. The bin is used to hold iron blocks. The rotating motor serves as the power source to control the rotation of the drum. The rotation of the drum drives the bin to rotate, which in turn drives the top cover to rotate. The rotation of the top cover drives the second connecting rod to rotate, which in turn drives the gear ring to rotate. Because the gear ring meshes with the rack teeth, the rotation of the gear ring causes the moving platform to move axially on the slide rail. At this time, the drum rotates, which in turn causes the pipe to rotate, and thus the pipe rotates. The pipe itself generates a precession torque, which resists the external torque, keeping the object stable. When the pipe moves to the quenching area, due to the high temperature, the iron block inside the chamber will expand and contract due to thermal expansion, and the overall volume will begin to increase, squeezing the top cover and causing it to move upward. The movement of the top cover drives the second connecting rod to move, and the movement of the second connecting rod drives the gear ring to move. Finally, the gear ring teeth disengage from the rack, and the moving platform stops moving. The pipe is still rotating under the drive of the rotating drum, thus quenching the pipe in conjunction with the high ambient temperature, without the need for an additional rotating motor to control the pipe.
[0015] A timing component is provided at the bottom of the compartment, and a movable plate is provided at the bottom of the compartment. The movable plate is slidably connected to the inner wall of the cavity. The timing component includes a support plate, a bimetallic strip, and a connecting rod. The support plate is located at the bottom of the movable plate, and the top of the support plate is rotatably connected to the bottom of the movable plate. The bimetallic strip is located at the bottom of the movable plate, and one end of the bimetallic strip is fixedly connected to the cavity. The other end of the bimetallic strip is provided with a connecting rod. One end of the connecting rod is fixedly connected to the bimetallic strip, and the other end of the connecting rod is fixedly connected to the bottom of the support plate. A second spring is provided between the top cover and the movable plate.
[0016] Furthermore, the timing component at the bottom of the chamber calculates the quenching time of the device. When the set time is reached, the chamber moves downward, causing the gear ring to contact the tooth edge, thus enabling the device to continue transporting. When the device is in a high-temperature environment, the external temperature affects the cavity, causing the bimetallic strip inside to heat up. The bimetallic strip bends towards the side with the lowest coefficient of expansion. Since one end of the bimetallic strip is connected to the bottom of the support plate via a connecting rod, and the support plate supports the moving plate, the bending of the bimetallic strip causes the bottom of the support plate to move towards the bimetallic strip. The support plate rotates and loses its supporting function, causing the moving plate to move downward. As the gear ring rotates, it meshes with the tooth edge, allowing the device to remain in the high-temperature environment for a certain period before moving. When the device leaves the high-temperature environment, the iron block inside the chamber first contracts, and the second spring causes the moving plate to move towards the top cover, i.e., the moving plate moves upward. Then, the support plate and bimetallic strip slowly return to their original positions, facilitating the next transport.
[0017] An electrical contact is provided between the bimetallic strip and the moving plate, with the side of the bimetallic strip with a low coefficient of expansion close to the moving plate.
[0018] Furthermore, there are two electrical contacts, located at the bottom end of the bimetallic strip and the bottom end surface of the moving plate, respectively. When the bimetallic strip bends, the distance between the two electrical contacts will change. At high temperatures, the higher the temperature, the closer the distance between them, and the smaller the resistance between them, thus indirectly determining the temperature inside the cavity. Then, due to the low coefficient of expansion being close to the moving plate, the bimetallic strip will only move towards the moving plate at high temperatures.
[0019] The top fixed assembly includes a column, a sliding platform, a drive motor, a telescopic column, and a turntable. The column is located on both sides of the track and on a horizontal ground. The top of the column is equipped with a slide rail, and the sliding platform is located on the slide rail. The fixed end of the drive motor is fixedly connected to the sliding platform, and the output end of the drive motor is equipped with a telescopic column. The bottom end of the telescopic column is equipped with a turntable.
[0020] Furthermore, the top fixing component is used to stabilize the top of the pipe and prevent it from shifting. The telescopic column is used to cooperate with the thermal expansion of the iron block inside the chamber to prevent it from squeezing the drive motor. The cooperation between the telescopic column and the drive motor can accommodate pipes of different heights. The column is used to support the sliding platform in the air. The sliding platform will move together with the moving platform during operation. The drive motor is used as a power source to control the movement of the telescopic column. The bottom of the turntable cooperates with the top of the pipe, and the top of the turntable is rotatably connected to the bottom of the telescopic column.
[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. When the bottom end of the pipe is placed inside the rotating drum, the top end of the sliding block moves downward under the pressure of the pipe. The threaded rod rotates, causing the auxiliary rotating block to rotate. The auxiliary rotating block causes one end of the rotating rod to move, thereby pushing the limiting block to move at the other end of the rotating rod. Since the limiting block is slidably connected to the sliding groove, the limiting block will only move axially along the sliding groove. As a result, when the rotating rod pushes the limiting block, the limiting block will move away from the central axis of the limiting post, thus fixing the inner wall of the pipe.
[0022] 2. In this invention, the rotating motor is used as a power source to control the rotation of the drum. The rotation of the drum will drive the gear ring to rotate. Since the gear ring meshes with the tooth edge of the rack, the rotation of the gear ring will drive the moving platform to move axially on the slide rail. The rotation of the drum will drive the pipe to rotate, and then the pipe will rotate. The pipe itself will generate a precession torque, which will resist the external torque and keep the object stable.
[0023] 3. When the pipe moves to the quenching area, due to the high temperature, the iron block inside the chamber will expand and contract due to thermal expansion and contraction, and the overall volume will begin to increase, squeezing the top cover and causing it to move upward. The movement of the top cover drives the second connecting rod to move, and the movement of the second connecting rod drives the gear ring to move. Finally, the gear ring teeth disengage from the rack, and the moving table stops moving. The pipe is still rotating under the drive of the rotating drum, thus quenching the pipe in conjunction with the high ambient temperature, without the need for an additional rotating motor to control the pipe.
[0024] 4. When the device is in a high-temperature environment, the external temperature will affect the cavity. The bimetallic strip inside the cavity will be heated and will bend towards the side with the lower coefficient of expansion. When the bimetallic strip bends, it will drive the bottom end of the support plate to move towards the bimetallic strip. The support plate will rotate and lose its supporting function. The moving plate will move downward. The gear ring will mesh with the tooth edge as it rotates, so that it can move after a certain period of time in a high-temperature environment, thus realizing automatic control.
[0025] 5. When the device of this invention leaves the high-temperature environment, the iron block inside its chamber will first contract, and the second spring will drive the moving plate to move towards the top cover, that is, the moving plate moves upward. Then the support plate and the bimetallic sheet will slowly return to their original positions, ready for the next transport. Attached Figure Description

[0028] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example: Figures 1-9 As shown, the present invention provides a pipe fitting transfer device with anti-sway function. The transfer device includes a transport component 1, a bottom fixing component 2, a top fixing component 3, and a pressure-bearing component 4. The bottom fixing component 2 is provided on the upper surface of the transport component 1, and the pressure-bearing component 4 is provided inside the bottom fixing component 2. The pressure-bearing component 4 is used to fix the pipe fitting. The bottom end of the bottom fixing component 2 is provided with a driving component 5, which is used to control the rotation of the bottom fixing component 2. The transport component 1 includes a track 11 and a movable platform 12. The track 11 is located on a horizontal ground, and the movable platform 12 is located on the track 11. The movable platform 12 is slidably connected to the track 11. A groove 121 is opened on the upper surface of the movable platform 12, and a gear groove 122 is opened in the groove 121. The two sides of the movable platform 12 are slidably engaged with the track 11. A rack 13 is provided on one side of the track 11, and the rack 13 is located on the side of the track 11 close to the movable platform 12.
[0030] Specifically, the transfer device is used to transport large pipe fittings. Since the pipe fittings are about 12 meters long and weigh about 4 to 6 tons, if the movement speed is too fast during transport, they will shake or shift due to their own weight, which will damage the fixing components. Since the pipe fittings need to be quenched later, they need to be rotated. Therefore, the base not only needs to fix the bottom end of the pipe fitting, but also needs to rotate the pipe fitting. In addition, the internal components must be resistant to high temperature. The transport component 1 is used to drive the pipe fitting to move, the bottom fixing component 2 is used to fix the bottom end of the pipe fitting, the top fixing component 3 is used to fix the top end of the pipe fitting, the pressure component 4 is used to fix the bottom end of the pipe fitting when it is placed on the bottom fixing component 2, and the drive component 5 is used to control the rotation of the bottom fixing component 2. The moving platform 12 is provided with connecting parts corresponding to the rails 11 on both sides, which are used to make the moving platform 12 move axially based on the rails 11. There are two rails 11, and each rail 11 is provided with a rack 13 on one side.
[0031] like Figures 3-5 As shown, the bottom fixing assembly 2 includes a rotating cylinder 21, a limiting post 22, and a threaded rod 23. The rotating cylinder 21 is located inside the groove 121 and is rotatably connected to the bottom end of the inner wall of the groove 121. The limiting post 22 is located inside the rotating cylinder 21 and is fixedly connected to the bottom end of the inner wall of the rotating cylinder 21. A circular groove 221 is opened in the limiting post 22, and a threaded rod 23 is provided in the circular groove 221. The threaded rod 23 is rotatably connected to the inner wall of the circular groove 221. A secondary rotating block 24 is sleeved on the body of the threaded rod 23 and is fixedly connected to the threaded rod 23. A main rotating block 25 is sleeved on the bottom end of the threaded rod 23 and is threadedly engaged with the threaded rod 23.
[0032] Specifically, the limiting post 22 in the bottom fixing component 2 is matched with the inner hole at the bottom end of the pipe fitting. The diameter of the limiting post 22 is smaller than the diameter of the pipe fitting. The limiting post 22 is located inside the rotating cylinder 21. The gap between the inner wall of the rotating cylinder 21 and the limiting post 22 is used to place the pipe. The top of the limiting post 22 has a groove 121 for placing the threaded rod 23. The upper and lower ends of the threaded rod 23 are rotatably connected to the upper and lower ends of the inner wall of the groove 121. The middle of the threaded rod 23 is fitted with a secondary rotating block 24, which is driven to rotate by the threaded rod 23. The bottom end of the threaded rod 23 is fitted with a main rotating block 25, which is used to control the rotation of the threaded rod 23. When the main rotating block 25 moves up and down, it will drive the threaded rod 23 to rotate. The rotation of the threaded rod 23 will drive the secondary rotating block 24 to rotate.
[0033] like Figures 4-7 As shown, a rotating rod 26 is provided on the upper surface of the auxiliary rotating block 24. One end of the rotating rod 26 is rotatably connected to the upper surface of the auxiliary rotating block 24, and the other end of the rotating rod 26 is rotatably connected to the limiting block 27. A sliding groove 222 is provided in the limiting post 22. The sliding groove 222 is connected to the circular groove 221, and the limiting block 27 is slidably connected to the sliding groove 222.
[0034] Specifically, when the main rotating block 25 moves downward, the rotation of the threaded rod 23 will drive the auxiliary rotating block 24 to rotate. The auxiliary rotating block 24 will drive one end of the rotating rod 26 to move, thereby pushing the limiting block 27 to move. Since the limiting block 27 is slidably connected to the slide groove 222, the limiting block 27 will only move axially along the slide groove 222. Therefore, when the rotating rod 26 pushes the limiting block 27, the limiting block 27 will move away from the central axis of the limiting post 22. Conversely, when the main rotating block 25 moves upward, the rotating rod 26 will drive the limiting block 27 to move towards the central axis of the limiting post 22. The final effect is that when the pipe is placed in the rotating drum 21, the main rotating block 25 moves downward, and the limiting block 27 moves outward to contact the inner wall of the pipe, fixing the inner wall of the pipe, thereby fixing the bottom end of the pipe. When the pipe is transferred, the main rotating block 25 moves upward, and the limiting block 27 moves inward, releasing the fixation of the inner wall of the pipe.
[0035] like Figure 5 , Figure 6 , Figure 8 As shown, the pressure-bearing component 4 includes a sliding block 41 and a bottom block 42. The sliding block 41 is slidably connected to the limiting post 22. A first connecting rod 43 is provided on one side of the sliding block 41. One end of the first connecting rod 43 is fixedly connected to the sliding block 41, and the other end of the first connecting rod 43 is fixedly connected to the main rotating block 25. The bottom block 42 is located at the bottom end of the limiting post 22 and is fixedly connected to the limiting post 22. A through groove 411 is provided in the sliding block 41, and a first spring 44 is provided between the sliding block 41 and the bottom block 42.
[0036] Specifically, the pressure-bearing component 4 contacts the bottom surface of the pipe fitting and moves under the pressure of the pipe fitting's weight. The sliding block 41 is located between the limiting post 22 and the rotating cylinder 21. The sliding block 41 is slidably connected to the outer wall of the limiting post 22, and the sliding block 41 is connected to the main rotating block 25 through the first connecting rod 43. When the top of the sliding block 41 moves downward under the pressure of the pipe fitting, it will drive the first connecting rod 43 to move downward. The first connecting rod 43 will drive the main rotating block 25 to move. However, due to the restriction of the first connecting rod 43, the main rotating block 25 will not rotate, and only the threaded rod 23 will rotate. Finally, the bottom of the downward-moving sliding block 41 will contact the top of the bottom block 42. The first spring 44 between the sliding block 41 and the bottom block 42 is used to keep the sliding block 41 and the bottom block 42 in a normally separated state.
[0037] like Figure 4 , Figure 8As shown, the drive assembly 5 includes a chamber 51, a top cover 52, a gear ring 53, and a rotating motor 54. A cavity 223 is provided inside the limiting post 22, and the chamber 51 is located inside the cavity 223. The bottom end of the chamber 51 is fixedly connected to the cavity 223. The top cover 52 is slidably connected to the chamber 51. A second connecting rod 55 is provided on one side of the top cover 52. One end of the second connecting rod 55 is fixedly connected to the top cover 52, and the other end of the second connecting rod 55 is fixedly connected to the gear ring 53. The gear ring 53 meshes with the tooth edge of the rack 13. The chamber 51 is used to store iron blocks. The fixed end of the rotating motor 54 is fixedly connected to the bottom end of the moving platform 12, and the output end of the rotating motor 54 is fixedly connected to the bottom end of the rotating drum 21.
[0038] Specifically, the drive component 5 is used to control the movement of the transport component 1. The cavity 223 is used to house the bin 51 and the top cover 52, and provides space for the top cover 52 to move. The bin 51 is used to hold iron blocks. The rotating motor 54 is used as a power source to control the rotation of the rotating drum 21. The rotation of the rotating drum 21 will drive the bin 51 to rotate, which in turn will drive the top cover 52 to rotate. The rotation of the top cover 52 will drive the second connecting rod 55 to rotate, which will drive the gear ring 53 to rotate. Since the gear ring 53 meshes with the tooth edge of the rack 13, the rotation of the gear ring 53 will drive the moving platform 12 to move axially on the slide rail. At this time, the rotating drum 21 will rotate, and the rotation of the rotating drum 21 will drive the pipe fittings to move. The pipe rotates, generating a precession torque that counteracts the external torque, keeping the object stable. When the pipe moves to the quenching area, the iron block inside the chamber 51 expands and contracts due to the high temperature, increasing its overall volume and pressing against the top cover 52, causing it to move upwards. The movement of the top cover 52 drives the second connecting rod 55 to move, which in turn drives the gear ring 53 to move. Eventually, the teeth of the gear ring 53 disengage from the rack 13, and the moving platform 12 stops moving. The pipe remains in a rotating state under the influence of the rotating drum 21, thus quenching the pipe in conjunction with the high ambient temperature without the need for an additional rotating motor 54 to control the pipe.
[0039] like Figure 8 As shown, a timing component 6 is provided at the bottom of the compartment 51, and a movable plate 57 is provided at the bottom of the compartment 51. The movable plate 57 is slidably connected to the inner wall of the cavity 223. The timing component 6 includes a support plate 61, a bimetallic strip 62, and a connecting rod 63. The support plate 61 is located at the bottom of the movable plate 57, and the top of the support plate 61 is rotatably connected to the bottom of the movable plate 57. The bimetallic strip 62 is located at the bottom of the movable plate 57, and one end of the bimetallic strip 62 is fixedly connected to the cavity 223. The other end of the bimetallic strip 62 is provided with a connecting rod 63. One end of the connecting rod 63 is fixedly connected to the bimetallic strip 62, and the other end of the connecting rod 63 is fixedly connected to the bottom of the support plate 61. A second spring 64 is provided between the top cover 52 and the movable plate 57.
[0040] Specifically, the timing component 6 at the bottom of the chamber 51 is used to calculate the quenching time of the device. When the set time is reached, the chamber 51 is controlled to move downwards, so that the gear ring 53 contacts the tooth edge, and finally the device continues to transport. When the device is in a high-temperature environment, its external temperature will affect the cavity 223. The bimetallic strip 62 inside the cavity 223 will be heated, and the bimetallic strip 62 will bend towards the side with the lower coefficient of expansion. Since one end of the bimetallic strip 62 is connected to the bottom of the support plate 61 through the connecting rod 63, and the support plate 61 supports the moving plate 57, the bimetallic strip 62 will bend towards the side with the lower coefficient of expansion. When the bimetallic strip 62 bends, it causes the bottom of the support plate 61 to move toward the bimetallic strip 62. The support plate 61 rotates and loses its supporting function. The moving plate 57 moves downward. The gear ring 53, under rotation, will mesh with the tooth edge, allowing it to move after a certain period of time in a high-temperature environment. When the device leaves the high-temperature environment, the iron block inside its chamber 51 will first contract. The second spring 64 will then drive the moving plate 57 toward the top cover 52, that is, the moving plate 57 moves upward. Then the support plate 61 and the bimetallic strip 62 will slowly return to their original positions, facilitating the next transport.
[0041] like Figure 8 As shown, an electrical contact 65 is provided between the bimetallic strip 62 and the movable plate 57, and the side of the bimetallic strip 62 with a low coefficient of expansion is close to the movable plate 57.
[0042] Specifically, there are two electrical contacts 65, located at the bottom end of the bimetallic strip 62 and the bottom surface of the moving plate 57, respectively. When the bimetallic strip 62 bends, the distance between the two electrical contacts 65 will change. At high temperatures, the higher the temperature, the closer the distance between them, and the smaller the resistance between them, thus indirectly determining the temperature inside the cavity 223. Then, due to the low coefficient of expansion and its proximity to the moving plate 57, the bimetallic strip 62 will only move towards the moving plate 57 at high temperatures.
[0043] like Figure 9 As shown, the top fixing component 3 includes a column 31, a sliding platform 32, a drive motor 33, a telescopic column 34, and a turntable 35. The column 31 is located on both sides of the track 11 and is located on a horizontal ground. The top of the column 31 is provided with a slide rail, and the sliding platform 32 is located on the slide rail. The fixed end of the drive motor 33 is fixedly connected to the sliding platform 32. The output end of the drive motor 33 is provided with a telescopic column 34, and the bottom end of the telescopic column 34 is provided with a turntable 35.
[0044] Specifically, the top fixing component 3 is used to stabilize the top of the pipe and prevent it from shifting. The telescopic column 34 is used to cooperate with the thermal expansion of the iron block inside the chamber 51 to prevent it from squeezing the drive motor 33. The cooperation between the telescopic column 34 and the drive motor 33 can adapt to pipes of different heights. The column 31 is used to support the sliding platform 32 in the air. The sliding platform 32 will move together with the moving table 12 during operation. The drive motor 33 is used as a power source to control the movement of the telescopic column 34. The bottom of the turntable 35 cooperates with the top of the pipe, and the top of the turntable 35 is rotatably connected to the bottom of the telescopic column 34.
[0045] Working principle: When the bottom end of the pipe fitting is placed inside the rotating drum 21, the top end of the sliding block 41 moves downward under the pressure of the pipe fitting, which drives the first connecting rod 43 to move downward. The first connecting rod 43 drives the main rotating block 25 to move. However, due to the restriction of the first connecting rod 43, the main rotating block 25 will not rotate, and only the threaded rod 23 will rotate. The rotation of the threaded rod 23 will drive the auxiliary rotating block 24 to rotate. The auxiliary rotating block 24 will drive one end of the rotating rod 26 to move, so the other end of the rotating rod 26 will push the limiting block 27 to move. Since the limiting block 27 is slidably connected to the slide groove 222, the limiting block 27 will only move axially along the slide groove 222. Therefore, when the rotating rod 26 pushes the limiting block 27, the limiting block 27 will move away from the sliding groove 222. The movement of the limiting post 22 along its central axis fixes the inner wall of the tube. The rotating motor 54 acts as a power source to control the rotation of the rotating drum 21. The rotation of the drum 21 drives the chamber 51 to rotate, which in turn drives the top cover 52 to rotate. The top cover 52 then drives the second connecting rod 55, which in turn drives the gear ring 53 to rotate. Since the gear ring 53 meshes with the teeth of the rack 13, its rotation causes the moving platform 12 to move axially along the slide rail. The rotation of the drum 21 causes the tube to rotate, resulting in the tube itself generating a precession torque. This precession torque resists the external torque, keeping the object stable. Then, when the tube moves to the quenching area… Due to the high temperature, the iron block inside chamber 51 will expand and contract due to heat, causing its overall volume to increase. This will compress the top cover 52, causing it to move upwards. The movement of the top cover 52 will drive the second connecting rod 55 to move, which in turn will drive the gear ring 53 to move. Eventually, the teeth of the gear ring 53 will disengage from the rack 13, and the moving platform 12 will stop moving. Meanwhile, the pipe is still rotating under the drive of the rotating drum 21, thus allowing the pipe to be quenched in conjunction with the high ambient temperature. No additional rotating motor 54 is needed to control the pipe. When the device is in a high-temperature environment, the external temperature will affect the cavity 223. The bimetallic strip 62 inside the cavity 223 will be heated, and the bimetallic strip 62 will bend towards the side with the lowest coefficient of expansion. Because one end of the bimetallic strip 62 is connected to the bottom end of the support plate 61 via the connecting rod 63, and the support plate 61 supports the moving plate 57, when the bimetallic strip 62 bends, it will cause the bottom end of the support plate 61 to move towards the bimetallic strip 62. The support plate 61 will rotate and lose its supporting function, and the moving plate 57 will move downward. The gear ring 53 will mesh with the tooth edge under rotation, so that it can move after a certain period of time in the high temperature environment. When the device leaves the high temperature environment, the iron block in its chamber 51 will first contract, and the second spring 64 will drive the moving plate 57 to move towards the top cover 52, that is, the moving plate 57 will move upward. Then the support plate 61 and the bimetallic strip 62 will slowly return to their original positions, which will facilitate the next transportation.
