The bearing device includes: a bearing unit with its upper surface serving as a bearing surface; and multiple rows of buffer devices, each movably connected to the bearing unit, and capable of moving sequentially relative to the bearing unit, such that multiple rows of elastic buffer portions on the multiple rows of buffer devices are sequentially located on the bearing surface side of the bearing unit, with an accommodating space between adjacent rows of elastic buffer portions. Before the next cylindrical structure rolls to the target position on the bearing surface, a row of buffer devices can move relative to the bearing unit to a position between the target position of the next cylindrical structure and the previous cylindrical structure, so that the next cylindrical structure collides with the elastic buffer portion after reaching the target position, thereby reducing the probability of damage caused by direct collision between the next and previous cylindrical structures and reducing noise.

Description

Technical Field

[0001] This application relates to the field of pipe fittings technology, and in particular to a load-bearing device and a load-bearing method. Background Technology

[0002] During the production or repair of cylindrical structures such as pipe fittings, after the previous cylindrical structure is produced / repaired, it is rolled to a first designated position with a width equal to the diameter of the previous cylindrical structure. After the next cylindrical structure is produced / repaired, it is also rolled to a second designated position with a width equal to the diameter of the next cylindrical structure. The second designated position and the first designated position are adjacent to each other to reduce the space occupied.

[0003] However, since the diameter of the previous cylindrical structure is equal to the width of the first designated position, and the diameter of the next cylindrical structure is equal to the width of the second designated position, and the first and second designated positions are adjacent to each other, the next cylindrical structure will collide with the previous cylindrical structure and generate noise after moving to the second designated position. Summary of the Invention

[0006] In some embodiments, the bearing device is provided with a sliding track, at least a portion of which corresponds to the position of the bearing surface and is perpendicular to the extension direction of the accommodating space; The multiple buffer devices are slidably connected to the sliding track and can slide along the sliding track in sequence so that the multiple elastic buffer parts on the multiple buffer devices are located sequentially on the bearing surface side of the bearing device.

[0007] In some embodiments, the sliding track includes: a first straight track, which corresponds to the position of the bearing surface and is perpendicular to the extension direction of the accommodating space, and the starting point of the first straight track is located above the ending point of the first straight track. Each of the aforementioned buffer devices can slide from the starting point to the ending point of the first straight track under its own gravity.

[0008] In some embodiments, the sliding track includes: a second straight track, a first connecting track, a third straight track, and a second connecting track connected end to end to form a loop track. The second straight track is opposite to the third straight track and is located above the third straight track. The second straight track corresponds to the position of the bearing surface and is perpendicular to the extension direction of the accommodating space. The starting positions of both the second straight track and the third straight track are located above the ending positions. Each of the aforementioned buffer devices can slide along the sliding track from the starting point of the second straight track to the ending point of the third straight track under its own gravity.

[0009] In some embodiments, the carrying device may further include: a support device, which is connected at least to the lower position of the carrying device corresponding to the second connecting rail to support the carrying device, and the support device is provided with a lifting channel communicating with the second connecting rail; The lifting device, at least partially located within the lifting channel, is capable of providing lifting force to a series of buffer devices located within the second connecting track, so as to raise the series of buffer devices to the starting point of the second straight track.

[0010] In some embodiments, the bearing device may further include: a stop device disposed at one end of the bearing surface and corresponding to the end position of a segment on the sliding track corresponding to the bearing surface, wherein the stop device protrudes from the bearing surface and is offset from the buffer device to avoid the space required by the buffer device when sliding.

[0011] In some embodiments, the sliding track includes: a sliding space having a sliding opening; The buffer device further includes a sliding part and a connecting rod. The sliding part is slidably disposed in the sliding opening and abuts against the inner and outer walls of the sliding track corresponding to the sliding opening. The connecting rod is connected to the sliding part and the connecting rod is connected to the elastic buffer part.

[0012] In some embodiments, the buffer device further includes: a counterweight connected to the connecting rod, wherein the elastic buffer and the counterweight are respectively located on both sides of the sliding space, the counterweight is located below the elastic buffer and the weight of the counterweight is greater than the weight of the elastic buffer; and / or, The sliding space is provided with an entrance and exit adapted to the sliding part.

[0013] In some embodiments, the carrying device may further include: a lifting device disposed at one end of the carrying device corresponding to the starting point of the at least partial segment; A conveying device is disposed at the end of the lifting device away from the carrying device, and the conveying end point of the conveying device corresponds to the rising start point or falling start point of the lifting device.

[0014] In a second aspect, embodiments of this application provide a carrying method, applied to the carrying device described in any one of the embodiments of the first aspect, the carrying method comprising: Multiple pipe fittings roll sequentially along the bearing surface; Before the next pipe fitting rolls to the target position, a buffer device moves relative to the bearing device between the target position and the previous pipe fitting.

[0015] Through the above technical solution, the bearing device and bearing method provided in this application, when the first pipe is supported on the bearing surface, and the second pipe rolls towards the first pipe on the bearing surface before or during the rolling process (i.e., before the second pipe has rolled to the designated position on the bearing surface corresponding to the second pipe), a series of buffer devices can move relative to the bearing device to move the elastic buffer part of the series of buffer devices to the designated position between the second pipe and the first pipe. In this way, when the second pipe rolls to the designated position, it directly impacts the elastic buffer part instead of the first pipe, thereby reducing the possibility of collision damage to the first pipe and / or the second pipe caused by direct collision between the second pipe and the first pipe. At the same time, since the second pipe impacts the elastic buffer part, the elastic buffer part can provide elastic buffering force to the second pipe, thereby reducing the probability of collision damage when the second pipe collides with the buffer device. In addition, the elastic buffer part emits less noise when it collides, thereby reducing the risk of hearing damage to on-site personnel.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] During the production or repair of cylindrical structures such as pipe fittings, after the previous cylindrical structure is produced / repaired, it is rolled to a first designated position with a width equal to the diameter of the previous cylindrical structure. After the next cylindrical structure is produced / repaired, it is also rolled to a second designated position with a width equal to the diameter of the next cylindrical structure. The second designated position and the first designated position are adjacent to each other to reduce the space occupied.

[0028] However, because the diameter of the previous cylindrical structure is equal to the width at the first designated position, and the diameter of the next cylindrical structure is equal to the width at the second designated position, and the first and second designated positions are adjacent to each other, the next cylindrical structure will collide with the previous cylindrical structure and generate noise after moving to the second designated position. For example, in an oil drill pipe repair workshop, an average of 200 to 500 drill pipes need to be repaired every day. After the repaired drill pipes roll, they collide with other drill pipes and cause damage, while generating noise of 93-130 decibels.

[0029] While wrapping each pipe fitting with a buffer layer can reduce the probability of damage and noise from collisions, it also increases the labor and material costs associated with wrapping and removing the buffer layer. This application addresses this by connecting multiple rows of buffer devices 20, which can move relative to the support device 10, to the support device 10 that carries the pipe fittings. When the first pipe fitting 31 is supported on the support surface 101, and before or during the rolling of the second pipe fitting 32 towards the first pipe fitting 31 on the support surface 101 (i.e., before the second pipe fitting 32 reaches its designated position on the support surface 101), one row of buffer devices 20 can move relative to the support device 10, causing its elastic buffer portion 21 to move between the designated position of the second pipe fitting 32 and the first pipe fitting 31. Thus, the second pipe fitting... When component 32 rolls to the designated position, it directly impacts the elastic buffer 21 instead of the first pipe component 31. This reduces the likelihood of collision damage to the first pipe component 31 and / or the second pipe component 32 caused by direct collision between the second pipe component 32 and the first pipe component 31. Simultaneously, since the second pipe component 32 impacts the elastic buffer 21, the elastic buffer 21 can provide elastic buffering force to the second pipe component 32, thereby reducing the probability of collision damage when the second pipe component 32 collides with the buffer device 20. Furthermore, the elastic buffer 21 emits less noise during collision, thus reducing the risk of hearing damage to on-site personnel.

[0030] First aspect This application provides a carrier device 100, see [link to previous document]. Figures 1 to 8As shown, the supporting device 100 includes a supporting device 10 and multiple rows of buffer devices 20. The upper surface of the supporting device 10 is a supporting surface 101. The multiple rows of buffer devices 20 are movably connected to the supporting device 10, and the multiple rows of buffer devices 20 can move sequentially relative to the supporting device 10, so that multiple rows of elastic buffer portions 21 on the multiple rows of buffer devices 20 are sequentially located on the supporting surface 101 side of the supporting device 10, and there is an accommodating space 21A between two adjacent rows of elastic buffer portions 21. Here, the accommodating space 21A is the space where the pipe fitting is located after rolling. For example, the accommodating space 21A between the first row of buffer devices 20 and the second row of buffer devices 20 accommodates the second pipe fitting 32, while the accommodating space 21A between the second row of buffer devices 20 and the third row of buffer devices 20 accommodates the third pipe fitting.

[0031] When the first pipe fitting 31 is supported on the bearing surface 101, and before or during the rolling of the second pipe fitting 32 towards the first pipe fitting 31 on the bearing surface 101 (i.e., before the second pipe fitting 32 has rolled to its designated position on the bearing surface 101), a buffer device 20 can move its elastic buffer portion 21 between the designated position of the second pipe fitting 32 and the first pipe fitting 31 by moving relative to the bearing device 10. Thus, when the second pipe fitting 32 rolls to the designated position, it directly impacts the elastic buffer portion 21. The first pipe fitting 31 is not the first one, so as to reduce the possibility of collision damage to the first pipe fitting 31 and / or the second pipe fitting 32 due to direct collision between the second pipe fitting 32 and the first pipe fitting 31; at the same time, since the second pipe fitting 32 impacts the elastic buffer part 21, the elastic buffer part 21 can provide elastic buffering force to the second pipe fitting 32, thereby reducing the probability of collision damage when the second pipe fitting 32 collides with the buffer device 20. In addition, the elastic buffer part 21 emits less noise when it collides, so as to reduce the damage to the hearing of the personnel on site.

[0032] The bearing surface 101 can be a plane parallel to the horizontal plane, allowing the pipe fitting to roll on the bearing surface 101 under the push of a worker or pushing equipment. Alternatively, the bearing surface 101 can be a plane inclined to the horizontal plane, allowing the pipe fitting to roll on the bearing surface 101 under its own weight. For example, the angle between the bearing surface 101 and the horizontal plane can be 10 degrees, allowing the pipe fitting located on the bearing surface 101 to roll from a higher position to a lower position on the bearing surface 101 under its own weight. For ease of explanation, the following description uses an example where the bearing surface 101 has opposing first and second ends, and the pipe fitting rolls from the first end to the second end.

[0033] Among them, see Figure 7As shown, a sliding notch 102 can be provided on one side of the supporting device 10, and a row of buffer devices 20 is opposite to the sliding notch 102 and can slide from the outside of the sliding notch 102 into the sliding notch 102. A row of elastic buffer portions 21 of the buffer devices 20 located within the sliding notch 102 is located on the bearing surface 101 side of the supporting device 10, so as to buffer the collision of two adjacent pipe fittings. Simultaneously, the row of buffer devices 20 can slide in the opposite direction to return to its original position. Alternatively, the supporting device 10 can be provided with a through hole passing through the bearing surface 101, and a row of buffer devices 20 is located below the supporting device 10 so as to be able to rise through the through hole. The buffer device 20 can be positioned such that one row of elastic buffer sections 21 of the buffer device 20 is located on the bearing surface 101 side of the bearing device 10, so as to buffer the collision of two adjacent pipe fittings, and the buffer device 20 can be lowered to return to its original position; or, the buffer device 20 can be positioned above the bearing device 10, so that the elastic buffer sections 21 of the buffer device 20 can be lowered to be located on the bearing surface 101 side of the bearing device 10, so as to buffer the collision of two adjacent pipe fittings, and the buffer device 20 can be raised to return to its original position; or, the movement of the buffer device 20 relative to the bearing device 10 can be other arrangements, which will not be listed here. In the multi-row buffer device 20, the structure of the buffer devices 20 in different rows can be the same or different. The number of buffer devices 20 in the same row can be one or more. When there are multiple buffer devices 20 in a row, the structure of the multiple buffer devices 20 in the same row can be the same or different. One or more elastic buffer parts 21 can be provided on a buffer device 20. The elastic buffer parts 21 can be made entirely of elastic materials to simplify the manufacturing process, or they can be made of rigid structures such as iron or aluminum alloy inside, and the rigid structure is wrapped with elastic layers such as silicone, rubber, sponge, or nylon outside. When the second tube 32 collides with the elastic buffer part 21, it can provide impact force through the internal rigid structure and buffer protection and noise reduction through the external elastic layer of the second tube 32.

[0034] In some embodiments, see Figure 1 and Figure 2 As shown, the bearing device 10 is provided with a sliding track 11, at least a section of the sliding track 11 is positioned corresponding to the bearing surface 101 and perpendicular to the extension direction of the accommodating space 21A; multiple rows of buffer devices 20 are slidably connected to the sliding track 11 respectively, and can slide along the sliding track 11 in sequence, so that multiple rows of elastic buffer parts 21 on the multiple rows of buffer devices 20 are located on the bearing surface 101 side of the bearing device 10 in sequence.

[0035] Alternatively, it can be said that a portion or all of the sliding track 11 is located above or below the bearing surface 101 and is opposite to the bearing surface 101. When the multiple buffer devices 20 slide along the sliding track 11 in sequence, the multiple elastic buffer parts 21 on the multiple buffer devices 20 are located one after another on the bearing surface 101 side of the bearing device 10, and there is an accommodating space 21A between two adjacent elastic buffer parts 21. The sliding movement mode is not only simple to set up, but also easy to implement. It is understandable that when the first row of elastic buffers 21 slides relative to the sliding track 11 to the side of the bearing surface 101, it abuts against the first pipe 31 on the bearing surface 101. After the second pipe 32 rolls on the bearing surface 101, it will hit the first row of elastic buffers 21. Then, when the second row of elastic buffers 21 slides relative to the sliding track 11 to the side of the bearing surface 101, it abuts against the second pipe 32 on the bearing surface 101. By analogy, the first pipe 31, the first row of elastic buffers 21, the second pipe 32, the second row of elastic buffers 21, the third pipe, ... on the bearing surface 101 are arranged in sequence so that the bearing surface 101 can bear more pipes.

[0036] When the first end of the bearing surface 101 is positioned higher than the second end, causing the bearing surface 101 to tilt towards the horizontal plane, the positions of the multiple pipe fittings that roll sequentially from the first end to the second end of the bearing surface 101 rise. This allows the pipe fitting that rolls first and is in a lower position to provide support to the pipe fitting that rolls later and is in a higher position through a row of buffer devices 20 between the two pipe fittings that roll sequentially. The earlier the pipe fitting rolls, the greater the support force required. Therefore, in the multiple rows of buffer devices 20 that slide in sequence, the number of buffer devices 20 in the first row of buffer devices 20 can be greater than the number of buffer devices 20 in the subsequent row of buffer devices 20, so that the pipe fitting that rolls first can better support the pipe fitting that rolls later through the multiple buffer devices 20 in the row of buffer devices 20.

[0037] In some embodiments, the sliding track 11 includes: a first straight track, which corresponds to the position of the bearing surface 101 and is perpendicular to the extension direction of the accommodating space 21A, and the starting point of the first straight track is located above the ending point of the first straight track; each buffer device 20 can slide from the starting point of the first straight track to the ending point of the first straight track under its own gravity.

[0038] Alternatively, a first linear track extending in a straight line is provided above or below the bearing surface 101. The extension direction of the first linear track is perpendicular to the extension direction of the accommodating space 21A, and there is a height difference between the start and end points of the first linear track. This allows the multi-row buffer device 20 to slide along the first linear track from the first end of the corresponding bearing surface 101 to the second end of the corresponding bearing surface 101 under its own weight, without the need for a drive device. This reduces the need for drive device preparation, thereby lowering operating costs. It also reduces the wiring connection between the bearing device 100 and the drive device, improving operational safety. Furthermore, the self-sliding multi-row buffer device 20 can stop at the corresponding position based on the diameter of the previous pipe fitting, making it easier to buffer multiple pipe fittings of different diameters. Understandably, when a pipe fitting on the bearing surface 101 is removed, the multi-row buffer device 20 can slide along the first linear track to the end point under its own weight. At this point, it can be slid back to the starting point of the first linear track by workers or power equipment to prepare for the next buffering of multiple pipe fittings.

[0039] In other embodiments, see Figure 1 and Figure 2 As shown, the sliding track 11 includes: a second straight track 111, a first connecting track 112, a third straight track 113, and a second connecting track 114 connected end to end to form a loop. The second straight track 111 is opposite to the third straight track 113 and is located above the third straight track 113. The second straight track 111 corresponds to the bearing surface 101 and is perpendicular to the extension direction of the accommodating space 21A. The starting positions of both the second straight track 111 and the third straight track 113 are located above the ending positions. Each buffer device 20 can slide along the sliding track 11 from the starting point of the second straight track 111 to the ending point of the third straight track 113 under its own gravity.

[0040] Or, in other words, around the periphery of the supporting device 100, or as... Figure 1 and Figure 2The load-bearing device 100 shown is provided with a ring-shaped sliding track 11, and the second straight track 111 on the sliding track 11 corresponding to the load-bearing surface 101 is inclined so that each row of buffer devices 20 can slide along the second straight track 111 under its own weight without the need for a drive device to buffer the pipes on the load-bearing surface 101. This reduces the need for drive device preparation and lowers the operating cost. At the same time, it reduces the wiring connection between the load-bearing device 100 and the drive device, thereby improving operational safety. In addition, the self-sliding multi-row buffer devices 20 can stop at the corresponding position according to the diameter of the previous pipe, which makes it more convenient to buffer multiple pipes of different diameters. Furthermore, after the pipe fitting near the second end of the bearing surface 101 is removed, the buffer device 20 between the removed pipe fitting and the next pipe fitting can continue to slide along the first connecting track 112 and the third straight track 113 under its own gravity to the end position of the third straight track 113. At this time, the buffer device 20 can be lifted by workers or power equipment to the starting position of the second straight track 111 via the second connecting track 114 to prepare for the next buffering.

[0041] It should be noted that the second linear track 111 in this embodiment can be the same as or different from the first linear track in the previous embodiment.

[0042] In some embodiments, see Figure 1 and Figure 2 As shown, the supporting device 100 may further include a support device 40 and a lifting device 50. The support device 40 is connected at least to the lower position of the supporting device 10 corresponding to the second connecting rail 114 to support the supporting device 10, and the support device 40 is provided with a lifting channel 41 communicating with the second connecting rail 114. The lifting device 50 is at least partially located in the lifting channel 41 and is capable of providing lifting force to a row of buffer devices 20 located in the second connecting rail 114 so that the row of buffer devices 20 rises to the starting point of the second straight rail 111.

[0043] Alternatively, at least part of the support device 40 is located below the second connecting rail 114 and connected to the bearing device 10 to support the bearing device 10, thereby supporting the bearing device 10 at a certain height. This height can be easily accessible to workers so that the pipes on the bearing surface 101 of the bearing device 10 can be easily accessed by workers for convenient observation, sorting, cleaning, and maintenance of the pipes on the bearing surface 101. This height can also be a height at which other moving devices can easily grab the pipes on the bearing surface 101. At least part of the lifting device 50 is located in the lifting channel 41 on the support device 40 that communicates with the second connecting rail 114, thereby conveniently providing lifting force to the buffer device 20 in the second connecting rail 114, so that the buffer device 20 is located at the starting point of the second straight rail 111 in preparation for the next buffering.

[0044] Lifting device 50 may include, for example Figure 1 and Figure 2 The diagram shows a cylinder 51 and a piston rod 52 disposed within the lifting channel 41. The piston rod 52 can rise or fall relative to the cylinder 51, and the top of the piston rod 52 corresponds to the second connecting rail 114, enabling it to lift a portion of the buffer device 20 (e.g., the sliding part 22 hereinafter) within the second connecting rail 114. Alternatively, the lifting device 50 may include a nut and a lead screw disposed within the lifting channel 41. The lead screw extends vertically and is screwed into the nut. When a motor provides rotational power, the lead screw rotates relative to the nut to rise or fall, and the top of the lead screw corresponds to the second connecting rail 114, enabling it to lift a portion of the buffer device 20 (e.g., the sliding part 22 hereinafter) within the second connecting rail 114. Alternatively, the lifting device 50 may have other structural configurations.

[0045] In some embodiments, see Figure 1 and Figure 2As shown, the supporting device 100 may further include a stop device 60, disposed at one end of the supporting surface 101 and corresponding to the end position of the segment on the sliding track 11 corresponding to the supporting surface 101. The stop device 60 protrudes from the supporting surface 101 and is offset from the buffer device 20 to avoid the space required for the buffer device 20 to slide. In other words, when the first pipe 31 rolls on the supporting surface 101 to the second end of the supporting surface 101, it will abut against the stop device 60 to prevent it from rolling off the supporting surface 101. The offset between the stop device 60 and the buffer device 20 ensures that the placement of the stop device 60 does not affect the sliding of the buffer device 20. For example, there may be two stop devices 60, corresponding to both ends of the extending direction of the accommodating space 21A, while multiple rows of buffer devices 20 are positioned between the two stop devices 60 to avoid the space required for the buffer device 20 to slide. Here, the stop device 60 can be made of elastic materials such as rubber or silicone, or it can be a structure with a rigid internal structure and an elastic outer layer. This can reduce the probability of damage and noise to pipe fittings that collide directly with the stop device 60 during the collision.

[0046] In some embodiments, see Figure 1 and Figure 2 As shown, the sliding track 11 includes a sliding space 116 with a sliding opening 115; the buffer device 20 further includes a sliding part 22 and a connecting rod 23. The sliding part 22 is slidably disposed in the sliding opening 115 and abuts against the inner and outer walls of the sliding track 11 corresponding to the sliding opening 115. The connecting rod 23 is connected to the sliding part 22 and is also connected to the elastic buffer part 21. In other words, the elastic buffer part 21 of the buffer device 20 is connected to the sliding part 22 through the connecting rod 23, and the sliding part 22 can slide relative to the sliding space 116, thereby realizing that multiple rows of elastic buffer parts 21 move sequentially relative to the bearing device 10 and are located on the bearing surface 101 side of the bearing device 10.

[0047] In some embodiments, see Figures 1 to 6 As shown, the buffer device 20 further includes: a counterweight 24 connected to the connecting rod 23; the elastic buffer 21 and the counterweight 24 are respectively located on both sides of the sliding space 116; the counterweight 24 is located below the elastic buffer 21 and the weight of the counterweight 24 is greater than the weight of the elastic buffer 21; and / or, the sliding space 116 is provided with an inlet and outlet 1161 adapted to the sliding part 22 to enter and exit.

[0048] The counterweight 24 is located below the elastic buffer 21, and the weight of the counterweight 24 is greater than the weight of the elastic buffer 21. Thus, the weight at the lower end of the buffer device 20 is greater than the weight at the upper end, making the sliding process of the buffer device 20 along the sliding track 11 smoother. The sliding part 22 can be as follows: Figure 3 and Figure 5The bearing shown has two opposing parts forming the sliding opening 115 located in two opposite grooves on the bearing. A connecting rod 23 is sleeved on the bearing's axis, and both ends of the connecting rod 23 are connected to the elastic buffer part 21 and the counterweight part 24, respectively. Here, the two parts of the connecting rod 23 connecting the elastic buffer part 21 and the counterweight part 24 can both be plate-shaped structures, inserted into the elastic buffer part 21 and the counterweight part 24, respectively. A first pin 231 passes through the overlapping portion of the connecting rod 23 and the elastic buffer part 21, and a second pin 232 passes through the overlapping portion of the connecting rod 23 and the counterweight part 24, thus connecting both ends of the connecting rod 23 to the elastic buffer part 21 and the counterweight part 24, respectively. The inlet / outlet 1161 allows for convenient adjustment of the number of buffer devices 20 rows in the sliding track 11.

[0049] In some embodiments, see Figure 1 and Figure 2 As shown, the supporting device 100 may further include a lifting device 70 and a conveying device (not shown in the figure). The lifting device 70 is located at one end of the supporting device 10 corresponding to the starting point of at least a portion of the segment; the conveying device is located at the end of the lifting device 70 away from the supporting device 10, and the conveying endpoint of the conveying device corresponds to the rising or falling starting point of the lifting device 70. In other words, the conveying device can convey the pipe fittings, and after conveying, the lifting device 70 will raise or lower the pipe fittings to align them with the first end of the supporting surface 101, preparing the pipe fittings for rolling on the supporting surface 101. This achieves an integrated design of pipe fitting conveying, alignment, and collision buffering. The conveying device can be a conveyor belt or other conveying devices.

[0050] See one example. Figures 1 to 6 As shown, the carrier device 100 includes: The support device 10 has an upper surface 101 as a support surface. A sliding track 11 is provided below the support surface 101. The sliding track 11 includes: a second straight track 111, a first connecting track 112, a third straight track 113, and a second connecting track 114 connected end-to-end to form a ring track. The second straight track 111 is opposite to and above the third straight track 113. The second straight track 111 corresponds to the position of the support surface 101, and the starting point of either the second straight track 111 or the third straight track 113 is above the ending point. The sliding track 11 also includes an annular sliding space 116 with annular sliding openings 115 formed on the second straight track 111, the first connecting track 112, the third straight track 113, and the second connecting track 114.

[0051] Multiple buffer devices 20 are slidably connected to the sliding track 11. Each buffer device 20 can slide along the sliding track 11 from the starting point of the second straight track 111 to the ending point of the third straight track 113 under its own weight, so that the multiple elastic buffer parts 21 on the multiple buffer devices 20 are sequentially located on the bearing surface 101 side of the bearing device 10. The buffer device 20 includes: a sliding part 22, a connecting rod 23 and a counterweight part 24. The sliding part 22 is slidably disposed in the sliding opening 115 and abuts against the inner and outer walls of the sliding track 11 corresponding to the sliding opening 115, so as to be able to slide along the annular sliding opening 115. The connecting rod 23 is connected to the sliding part 22. The two ends of the connecting rod 23 corresponding to the two sides of the sliding space 116 are respectively connected to the elastic buffer part 21 and the counterweight part 24. The counterweight part 24 is located below the elastic buffer part 21 and the weight of the counterweight part 24 is greater than the weight of the elastic buffer part 21.

[0052] The support device 40 is connected at least below the second connecting rail 114 corresponding to the bearing device 10 to support the bearing device 10, and the support device 40 is provided with a lifting channel 41 that connects to the second connecting rail 114.

[0053] The lifting device 50 is at least partially located within the lifting channel 41 and is capable of providing lifting force to the buffer device 20 located within the second connecting rail 114, so that the buffer device 20 is raised to the starting point of the second straight rail 111.

[0054] Lifting device 70 is provided at one end of the bearing device 10 corresponding to the starting point of at least a portion of the segment. A conveying device is installed at the end of the lifting device 70 away from the carrying device 10, and the conveying end point of the conveying device corresponds to the rising start point or falling start point of the lifting device 70.

[0055] Second aspect This application provides a carrying method, applied to the carrying device 100 in any embodiment of the first aspect, see [link]. Figure 8 As shown, the bearing method includes: S101: Multiple pipe fittings roll sequentially along the bearing surface 101; S102: Before the next pipe fitting rolls to the target position, a buffer device 20 moves relative to the bearing device 10 to the target position and between the previous pipe fitting.

[0056] In other words, when the first pipe fitting 31 is supported on the bearing surface 101, and before or during the rolling of the second pipe fitting 32 (i.e., the next pipe fitting) towards the first pipe fitting 31 on the bearing surface 101, that is, before the second pipe fitting 32 has rolled to the designated position (i.e., the target position of the next pipe fitting) on ​​the bearing surface 101, a series of buffer devices 20 can move their elastic buffer parts 21 to between the designated position of the second pipe fitting 32 and the first pipe fitting 31 through relative movement to the bearing device 10; thus, the second pipe fitting 32 rolls to the designated position. The second pipe 32 impacts the elastic buffer 21 directly instead of the first pipe 31, which reduces the possibility of collision damage to the first pipe 31 and / or the second pipe 32 when they collide directly with the first pipe 31. At the same time, since the second pipe 32 impacts the elastic buffer 21, the elastic buffer 21 can provide elastic buffering force to the second pipe 32, thereby reducing the probability of collision damage when the second pipe 32 collides with the buffer device 20. In addition, the elastic buffer 21 emits less noise when it collides, which can reduce the damage to the hearing of the personnel on site.
