[0026] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] The following is for reference. Figures 1-2 This invention describes a pipeline transfer device according to an embodiment of the present invention. The pipeline transfer device can transfer vacuum pipelines required for nuclear fusion reactions, and can also transfer pipelines 50 from other systems.

[0028] like Figure 1 , Figure 2As shown, according to a first aspect embodiment of the present invention, the pipe transfer device includes: a device base, with a traveling wheel 30 at the lower end of the device base; a clamp assembly located above the device base, the clamp assembly including a plurality of clamps 41, the clamps 41 being used to clamp the pipe 50, the plurality of clamps 41 being movably disposed on the device base along a first direction, and the plurality of clamps 41 being arranged sequentially along the first direction, the first direction being perpendicular to the height direction of the pipe transfer device; the device base includes: an upper seat 21 and a lower seat 22, the upper seat 21 being movably disposed on the lower seat 22 along the height direction of the pipe transfer device, the clamp assembly being disposed on the upper seat 21; the clamps 41 The device includes two clamping parts 411, which are opposite each other along a second direction. The two clamping parts 411 can move closer or further apart to clamp or release the pipe 50. The first direction, the second direction, and the height direction of the pipe transfer device are perpendicular to each other. The pipe transfer device also includes a controller and a pressure detection element 60. The controller is communicatively connected to both the pressure detection element 60 and the clamp 41. The clamping parts 411 have clamping surfaces for clamping the pipe 50. At least one clamping surface of the clamping part 411 of the clamp 41 is provided with the pressure detection element 60. The controller is configured to adjust the interval between the two clamping parts 411 of the clamp 41 according to the detection information of the pressure detection element 60.

[0029] Among them, such as Figure 1 As shown, this application defines the first direction as the X direction. (As indicated...) Figure 1 As shown, this application defines the height direction of the pipeline transfer device as the Z direction. The device base can be made of materials such as steel or aluminum alloy, and can be formed by casting, milling, or other methods. The clamping assembly can include two, three, four, or other clamps 41, such as... Figure 1 As shown, this application uses a fixture assembly comprising two fixtures 41 as an example for illustration.

[0030] As one embodiment, the pipeline transfer device may include multiple pulley assemblies, which can be assembled one-to-one with multiple clamps 41. Each pulley assembly may include a driving pulley, a driven pulley, and a drive belt. The driving and driven pulleys are arranged along a first direction, and both are rotatably mounted on the device base around a second direction. The height direction, the second direction, and the first direction of the pipeline transfer device are perpendicular to each other. The drive belt can be sleeved on the driving and driven pulleys and is connected to the corresponding clamps 41. When the drive belt moves, it can drive the corresponding clamps 41 to move along the first direction. The multiple pulley assemblies can be arranged sequentially along the first direction on the upper end of the device base. The multiple clamps 41 can be fixed to the upper end of the drive belt of the multiple pulley assemblies respectively. By controlling the rotation direction of the driving pulleys of the multiple pulley assemblies, adjacent clamps 41 can be moved closer or further apart.

[0031] As an example, such as Figure 1 , Figure 2 As shown, the traveling wheel 30 may include a support frame 31, a wheel body 32, and a wheel locking structure 33. The support frame 31 may be welded to the device base, and the support frame 31 may be fixedly connected to the device base by bolts. The wheel body 32 may include a rotating shaft and a rolling wheel. Along the height direction of the pipeline transfer device, a wheel mounting groove may be formed on the side of the support frame 31 facing the wheel body 32. A bearing seat may be installed in the wheel mounting groove, and a rolling bearing may be embedded in the bearing seat. The rotating shaft may be fitted with the rolling bearing, and the rolling wheel may be fitted coaxially with the rotating shaft, allowing the rolling wheel to rotate flexibly around the rotating shaft. The locking structure may be a foot-operated brake pad structure, and the locking structure may be fixedly connected to the support frame 31. When the locking structure is pressed, the rolling wheel is locked and stops rotating. When the locking structure is released, the rolling wheel can rotate around the rotating shaft.

[0032] As an example, the pipeline transfer device can be equipped with multiple first support structures 90, which can ensure the stability of the pipeline transfer device in a fixed state. Along the height direction of the pipeline transfer device, the multiple first support structures 90 can all be located at the lower end of the device base, and all multiple first support structures 90 can be fixedly connected to the device base. The first support structure 90 can include a first plate 91, a second plate 92, a third plate 93, a first support column 94, and an anti-slip pad 95. The first plate 91 can be fixedly connected to the device base, the third plate 93 can be fixedly connected to the first support column 94, and the first support column 94 can be located below the third plate 93, and the third plate 93 can be located below the first plate 91. The second plate 92 can be located below the first plate 91 and above the third plate 93, and the second plate 92 can be fixedly connected to both the first plate 91 and the third plate 93. Along the height direction of the pipeline transfer device, the lower end of the first support column 94 can be fixedly equipped with an anti-slip pad 95. The anti-slip pad 95 can increase the friction between the first support structure 90 and the ground, which helps to reduce the risk of displacement of the pipeline transfer device when it is in a fixed state.

[0033] Exemplarily, the clamps 41 in the clamping assembly of this application are arranged sequentially along a first direction, and any two adjacent clamps 41 can move closer to each other or further apart along the first direction. As an example, by adjusting any two adjacent clamps 41 to move closer to each other, the spacing between the two adjacent clamps 41 can be reduced, enabling the clamping assembly to clamp shorter pipes 50. As another example, by adjusting any two adjacent clamps 41 to move further apart, the spacing between the two adjacent clamps 41 can be increased, enabling the clamping assembly to clamp longer pipes 50.

[0034] By adjusting the distance between any two adjacent clamps 41, which can be brought closer or further apart, the clamp assembly can be made to hold pipes 50 of different lengths. This makes the pipe transfer device adaptable to pipes 50 of different lengths and improves its versatility.

[0035] By simply adjusting any two adjacent clamps 41 to move closer or further apart, the clamping assembly can hold pipes 50 of different lengths. This reduces the need for manual handling of the pipes 50 and adjustments to their clamping positions, thus lowering labor costs. The clamping assembly of this application includes multiple clamps 41, which together clamp the pipe 50, improving clamping stability and reducing the risk of damage to the pipe 50 due to displacement during transport.

[0036] The lower end of the device base is equipped with casters 30, which allow the pipe transfer device to flexibly adjust its angle when transferring the pipe 50. This facilitates the pipe transfer device's adaptability to complex site layouts, such as those used in nuclear fusion experiments. The casters 30 can be used to move the pipe transfer device to a designated position to transfer the pipe 50 to a preset location. Once the pipe 50 is transferred to the preset position, the angle of the pipe 50 can be adjusted by moving the casters 30 to align the pipe 50's interface with the preset installation structure, thus aiding in the installation of the pipe 50.

[0037] As one embodiment, the lower seat 22 may be equipped with an electric push rod, and the pipe transfer device may include a controller. The electric push rod may extend along the height direction of the pipe transfer device and be fixedly connected to the upper seat 21. The electric push rod may be communicatively connected to the controller, and the controller may control the extension and retraction of the electric push rod to drive the upper seat 21 to move along the height direction of the pipe transfer device.

[0038] The upper seat 21 is movably mounted on the lower seat 22 along the height direction of the pipe transfer device. The clamp assembly is mounted on the upper seat 21 and can move synchronously with the upper seat 21, thereby adjusting the pipe 50 to different heights and aligning it with installation ports at different heights, facilitating pipe 50 installation. The height of the upper seat 21 can be lowered to allow the clamp assembly to be close to the ground or work surface for loading and unloading the pipe 50. When the pipe transfer device transfers the pipe 50 to a preset position, the position of the upper seat 21 along the height direction of the pipe transfer device can be adjusted to align the pipe 50 with installation ports at different heights. This reduces manpower consumption, improves the ease of operation of the pipe transfer device, and ultimately enhances the transfer efficiency of the pipe 50.

[0039] like Figure 2As shown, in this invention, the second direction is defined as the Y direction. As one embodiment, such as... Figure 2 As shown, the clamp 41 may include a third drive structure, which may include a cylinder and a piston rod 110. One end of the piston rod 110 may be connected to the output end of the cylinder, and the other end of the piston rod 110 may be fixedly connected to two clamping parts 411 through two connecting bodies 120. The pipeline transfer device includes a controller, which can control the cylinder to drive the piston rod 110 to extend and retract, thereby driving the two clamping parts 411 to move along the second direction.

[0040] The controller can control the cylinder to drive the piston rod 110 to extend and retract, causing the two clamping parts 411 to move closer to each other in the second direction, reducing the distance between the two clamping parts 411, so that the clamping assembly can clamp the pipe 50 with a smaller diameter. The controller can also control the cylinder to drive the piston rod 110 to extend and retract, causing the two clamping parts 411 to move further apart in the second direction, increasing the distance between the two clamping parts 411, so that the clamping assembly can clamp the pipe 50 with a larger diameter or release the pipe 50.

[0041] The two clamping parts 411 can move closer or further apart so that multiple clamps 41 can clamp pipes 50 of different diameters. This is beneficial for the clamping assembly to clamp pipes 50 of different diameters, for the pipe transfer device to transfer pipes 50 of different diameters, and for improving the versatility of the pipe transfer device.

[0042] Compared to traditional complex clamping structures, this utility model can achieve clamping and releasing of pipes 50 of different diameters by simply having two clamping parts 411 moving closer or further apart along the second direction. This simplifies the operation steps of transferring pipes 50, shortens the transfer time of pipes 50, and improves transfer efficiency.

[0043] The two clamping parts 411 are arranged opposite each other along the second direction. When the clamp 41 clamps the pipe 50, along the second direction, the clamp 41 can apply symmetrical clamping force to the pipe 50 from both sides. This is beneficial to improving the clamping stability of the clamping assembly, reducing the risk of the pipe 50 falling off during transportation, and also helps to balance the force on the pipe 50. This is beneficial to reducing the risk of the pipe 50 deforming and wearing due to stress concentration, and also helps to protect the integrity of the pipe 50.

[0044] The controller can be an operator's computer or other equipment. The pressure detection element 60 can be a pressure sensor. The controller, pressure detection element 60, and clamp 41 can all communicate via Bluetooth, WIFI, or other means. As one embodiment, the clamping surface of one clamping part 411 of the clamp 41 is provided with the pressure detection element 60. As another embodiment, both clamping surfaces of the two clamping parts 411 of the clamp 41 are provided with the pressure detection element 60. The controller can preset multiple sets of reasonable pressure parameter value ranges for pipes 50 of different diameters.

[0045] The pressure sensing element 60 can collect the contact pressure between the clamping surface and the pipe 50 in real time. After receiving the contact pressure data, the controller can control the clamp 41 to adjust the interval between the two clamping parts 411 that are opposite each other in the second direction. When the contact pressure data received by the controller is low, the controller can control the clamp 41 to adjust the two clamping parts 411 that are opposite each other in the second direction to move closer to each other, so as to shorten the interval between the two clamping parts 411 that are opposite each other in the second direction.

[0046] When the contact pressure data received by the controller is large, the controller can control the clamp 41 to adjust the two clamping parts 411 that are opposite each other along the second direction to move further apart, thereby increasing the distance between the two clamping parts 411 that are opposite each other along the second direction. Therefore, by setting up the controller and the pressure detection element 60, the risk of deformation and wear of the pipe 50 due to excessive clamping force can be reduced, and the risk of loosening of the pipe 50 due to insufficient clamping force can also be reduced. This helps to reduce the risk of the pipe 50 falling off during transportation and helps to ensure the clamping stability of the clamp 41 on the pipe 50.

[0047] This invention adjusts the spacing between the two clamping parts 411 of the clamp 41 according to the detection information of the pressure detection element 60 by the controller, which is conducive to realizing the automated and intelligent control of the pipeline transfer device, reducing the labor cost of the pipeline transfer device, reducing the operation difficulty of the pipeline transfer device, and improving the transfer efficiency of the pipeline 50.

[0048] According to the first aspect of the present invention, the pipe transfer device facilitates the adjustment of the pipe 50 to different heights, enables the pipe transfer device to adapt to pipes 50 of different lengths and diameters, and improves the versatility of the pipe transfer device.

[0049] In some examples of embodiments of this utility model, such as Figure 2 As shown, the pipeline transfer device also includes a first drive structure 70, which is disposed on the device base and is assembled with multiple clamps 41. The first drive structure 70 is used to drive the multiple clamps 41 to move along a first direction to adjust the interval between any two adjacent clamps 41.

[0050] In one embodiment, the first drive structure 70 may include the multiple pulley assemblies described in the above embodiments. In another embodiment, the first drive structure 70 may include a rack and pinion transmission mechanism, which may include a rack, multiple gears, and multiple drive motors. The multiple gears may be assembled one-to-one with multiple clamps 41. The rack may be fixed to the device base, and the multiple drive motors may be assembled one-to-one with each of the multiple gears. Each drive motor can drive its corresponding gear to rotate, thereby driving the multiple clamps 41 to move along a first direction on the rack, causing the multiple clamps 41 to move closer to or further away from each other.

[0051] As an example, by adjusting any two adjacent clamps 41 among the multiple clamps 41 to be closer together, the spacing between the two adjacent clamps 41 can be reduced, so that the two ends or critical positions of the shorter pipe 50 can be stably clamped by the clamp assembly. As another example, by adjusting any two adjacent clamps 41 among the multiple clamps 41 to be farther apart, the spacing between the two adjacent clamps 41 can be increased, so that the two ends or critical positions of the longer pipe 50 can be stably clamped by the clamp assembly.

[0052] The first drive structure 70 drives multiple clamps 41 to move along a first direction. The spacing between any two adjacent clamps 41 can be adjusted, which allows the clamp assembly to hold pipes 50 of different lengths. This further enhances the pipe transfer device's adaptability to pipes 50 of different lengths, improving its versatility. It also ensures that each clamp 41 can be positioned appropriately to hold the pipe 50. The operator only needs to control the first drive structure 70 to adjust the spacing between any two adjacent clamps 41, enabling the clamp assembly to hold pipes 50 of different lengths, thus improving the ease of operation of the pipe transfer device.

[0053] In some examples of embodiments of this utility model, such as Figure 2 As shown, the first drive structure 70 includes: a first drive screw 71 and a plurality of moving blocks 72. The first drive screw 71 extends along a first direction and is rotatably disposed on the device base around the first direction. The moving blocks 72 are formed with first threaded holes. The first drive screw 71 passes through the first threaded holes of the plurality of moving blocks 72. A plurality of clamps 41 are respectively fixed to the plurality of moving blocks 72.

[0054] The first drive structure 70 may include two, three, four, or other movable blocks 72. This invention will be described using an example where the first drive structure 70 includes two movable blocks 72. Multiple clamps 41 are respectively fixed to multiple movable blocks 72, and the clamps 41 and movable blocks 72 can be assembled in a one-to-one correspondence. Along the height direction of the pipeline transfer device, the clamps 41 can be fixed above the movable blocks 72. The clamps 41 can be fixed to the movable blocks 72 using fasteners such as bolts and clips, or they can be welded to the movable blocks 72.

[0055] As one embodiment, the two clamps 41 and the two moving blocks 72 can be assembled one-to-one. The first drive screw 71 includes a first screw segment and a second screw segment arranged along a first direction. The threads of the first screw segment and the second screw segment have opposite directions. The two moving blocks 72 are respectively assembled one-to-one with the first screw segment and the second screw segment.

[0056] As one example, the first drive screw 71 rotates clockwise around a first direction, and the first and second screw segments respectively drive two moving blocks 72 to move closer to each other along the first direction, thus shortening the distance between the two clamps 41 fixed to the two moving blocks 72. This allows the clamp assembly to clamp shorter pipes 50. As another example, the first drive screw 71 rotates counterclockwise around the first direction, and the first and second screw segments respectively drive two moving blocks 72 to move further apart along the first direction, thus increasing the distance between the two clamps 41 fixed to the two moving blocks 72. This allows the clamp assembly to clamp longer pipes 50. Therefore, this invention, by driving multiple clamps 41 to move along the first direction through the first drive structure 70, is more conducive to enabling the clamp assembly to clamp pipes 50 of different lengths, more conducive to adapting the pipe transfer device to pipes 50 of different lengths, and more conducive to improving the versatility of the pipe transfer device.

[0057] As an example, a mounting base can be fixedly provided above the device base. There can be multiple mounting bases, which are arranged sequentially along the first direction. The mounting base can be provided with a bearing structure, which can include an outer ring and an inner ring. The outer ring is fixed to the mounting base and is sleeved on and fixedly connected to the first drive screw 71, so that the first drive screw 71 can rotate around the first direction.

[0058] As an example, the first drive structure 70 may include a motor, the output end of which may be fixedly connected to one end of the first drive screw 71 along a first direction. The pipe transfer device may include a controller, and the motor may be communicatively connected to the controller, which can drive the motor to rotate forward or reverse, thereby driving the first drive screw 71 to rotate around the first direction. As another example, the pipe transfer device may include a hand crank. Along the first direction, one end of the first drive screw 71 extends out of the device base, and the hand crank may be fixedly mounted to the first drive screw 71. An operator can drive the first drive screw 71 to rotate around the first direction by turning the hand crank.

[0059] Compared to other transmission methods, the lead screw drive used in this invention offers higher precision and faster speed, allowing for precise control of the moving distance of the moving block 72 and thus accurate adjustment of the spacing between any two adjacent clamps 41. The first drive lead screw 71 passes through the first threaded holes of multiple moving blocks 72, which helps improve the structural compactness of the pipeline transfer device and enhances its integration.

[0060] Multiple clamps 41 are fixed to multiple moving blocks 72, which helps reduce the risk of pipe 50 shifting or colliding due to relative displacement during the movement of the clamps 41 and moving blocks 72. Compared with traditional hoisting and transportation methods, this utility model only uses the first drive structure 70 to drive multiple clamps 41 to move along the first direction to clamp pipes 50 of different lengths. This simplifies the operation of transporting pipes 50, reduces manpower input, and allows the pipe transportation device to quickly adapt to pipes 50 of different lengths, shortening preparation time and thus improving transportation efficiency, which in turn helps improve the progress efficiency of nuclear fusion projects.

[0061] In some examples of embodiments of this utility model, there are two moving blocks 72 and two clamps 41, and the moving blocks 72 and clamps 41 are assembled in a one-to-one correspondence. The first drive screw 71 is used to drive the two clamps 41 to move closer to or further away from each other.

[0062] The first drive screw 71 can drive the two clamps 41 to move closer or further apart, thereby enabling the two clamps 41 to stably clamp the two ends of pipes 50 of different lengths along the first direction. This is more conducive to improving the clamping stability of the clamping assembly and reducing the risk of pipe 50 shifting during transport. Compared to using three or more moving blocks 72 and clamps 41, this application uses two moving blocks 72 and clamps 41, which helps to reduce the number of parts in the pipe transport device and reduce the production cost of the pipe transport device.

[0063] In some examples of embodiments of the present invention, a guide groove extending in a first direction is formed at one end of the device base facing the clamp assembly, and a guide block is formed in the clamp 41, the guide block being inserted into the guide groove.

[0064] The guide groove extends along the first direction, and the clamp 41 has a guide block inserted into the guide groove, which helps to restrict the clamp 41 to move only along the first direction. The guide block formed in the clamp 41 and inserted into the guide groove helps to improve the stability of the pipeline transfer device during the transfer of the pipeline 50, and helps to reduce the risk of the clamp 41 shaking or tilting during the transfer of the pipeline 50, which may cause the pipeline 50 to collide, thereby reducing the risk of damage to the integrity and sealing of the pipeline 50.

[0065] In some examples of embodiments of this utility model, such as Figure 2 As shown, the pipeline transfer device further includes: a second drive structure, the lower seat 22 includes a guide tube 221 extending along the height direction of the pipeline transfer device, the upper seat 21 includes a guide post 222 extending along the height direction of the pipeline transfer device, at least a portion of the guide post 222 is inserted into the guide tube 221 from the upper end of the guide tube 221, there are multiple guide posts 222 and multiple guide tubes 221, and the multiple guide posts 222 and multiple guide tubes 221 correspond one-to-one, the second drive structure is used to drive the upper seat 21 to rise and fall.

[0066] The guide tube 221 can be made of materials such as steel or aluminum alloy, and can be constructed into a cylindrical tube, a square tube, or other shapes. The guide post 222 can be made of materials such as steel or aluminum alloy, and can be constructed into a cylindrical post, a square post, or other shapes.

[0067] As one embodiment, the second drive structure may include the electric push rod in the above embodiments. As another embodiment, the second drive structure may include a drive motor and a second drive screw 81, at least one guide post 222 may have a second threaded hole 223 with an open lower end, the second drive screw 81 may be located in the corresponding guide tube 221 and extend along the height direction of the pipeline transfer device, the upper end of the second drive screw 81 may be fitted into the second threaded hole 223, and the second drive screw 81 may be connected to the drive motor for transmission.

[0068] At least a portion of the guide post 222 is inserted into the guide tube 221 from the upper end of the guide tube 221, and multiple guide posts 222 and multiple guide tubes 221 correspond one-to-one. This helps ensure the stability of the upper body 21 when it moves along the height direction of the pipe transfer device, and helps reduce the risk of pipe 50 shaking. The presence of multiple guide posts 222 and guide tubes 221 allows the pipe transfer device to support heavier pipes 50. Simultaneously, by driving the upper body 21 to rise and fall through the second drive structure, the pipe 50 can be adjusted to different heights, aligning it with installation ports at different heights, making pipe 50 installation easier.

[0069] In some examples of embodiments of this utility model, such as Figure 2 As shown, the second drive structure includes: a drive motor and a second drive screw 81, at least one guide post 222 having a second threaded hole 223 with its lower end open, the second drive screw 81 being located in the corresponding guide tube 221 and extending along the height direction of the pipeline transfer device, the upper end of the second drive screw 81 being fitted into the second threaded hole 223, and the second drive screw 81 being connected to the drive motor in a transmission manner.

[0070] The second drive screw 81 is located within the corresponding guide tube 221, and its upper end is fitted into the second threaded hole 223. The second drive screw 81 does not require external space in the pipe transfer device, thus improving the device's structural compactness. The drive motor can communicate with the controller, driving the second drive screw 81 to move along the height direction of the pipe transfer device, raising and lowering the upper seat 21, which in turn raises and lowers the clamp 41 to lift and lower the pipe 50. This facilitates further automated and intelligent control of the pipe transfer device, reduces labor costs, lowers operational complexity, and improves the transfer efficiency of the pipe 50.

[0071] When transferring pipe 50, the controller first controls the cylinder of the third drive structure to extend and retract the piston rod 110, thereby driving the two clamping parts 411 of the clamp 41 to move away from each other in the second direction, increasing the distance between the two clamping parts 411, and opening the clamp 41. Then, the operator can place one end of the pipe 50 to be transferred between the two clamping parts 411 of the opened clamp 41, and drive the first drive screw 71 to rotate around the first direction through the first drive structure 70, causing the moving block 72 to move in the first direction, thereby driving the two clamps 41 fixed to the two moving blocks 72 to adjust to a preset position adapted to the length of the pipe 50.

[0072] Then, the other end of the pipe 50 can be placed between the two clamping parts 411 of another clamp 41. The controller then controls the cylinder to extend and retract the piston rod 110, driving the two clamping parts 411 to move closer together in the second direction to clamp the pipe 50. Simultaneously, the pressure detection element 60 can collect clamping pressure data in real time and feed it back to the controller. When the controller detects that the pressure data is within a preset reasonable pressure range, the controller stops the cylinder. Afterwards, the wheel locking structure 33 is lifted, releasing the traveling wheels 30 from their locked state, propelling the pipe transfer device to move within the complex terrain and transferring the pipe 50 to the preset installation position.

[0073] Upon reaching the designated position, the operator depresses the wheel locking structure 33 to lock the traveling wheels 30 and controls the first support column 94 of the first support structure 90 to contact the ground, thus stabilizing the pipeline transfer device. Then, the second drive structure drives the upper seat 21 to rise and fall along the height direction of the pipeline transfer device, thereby raising and lowering the clamp assembly and the pipeline 50 along the height direction of the pipeline transfer device, adjusting the pipeline 50 to the correct height that matches the installation interface. Finally, the controller controls the clamp 41 to release, completing the transfer of the pipeline 50.
