[0060] Although the present invention can be easily embodied as embodiments of different forms, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to that described herein.

[0061] Thus, a feature indicated in this specification is intended to illustrate one of the features of one embodiment of the present invention, rather than implying that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise noted, the described combinations are not intended to be limiting.

[0062] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0063] The utility model provides a transport stand suitable for transporting columnar cargo, which can be steel coils or aluminum coils, or other types.

[0064] For ease of description, the length direction of the transport frame is defined as the longitudinal direction and the width direction as the transverse direction.

[0065] When the transport seat is transporting goods, the axis of the goods extends in the transverse direction.

[0066] Figure 1 shows a schematic diagram of the structure of the transport frame, Figure 2 Shown Figure 1 A local enlarged schematic diagram of Figure 3 Shows a structural diagram of the transport frame from another perspective, Figure 4 shows a schematic front view of the transport frame, Figure 5 Shown Figure 4 The main view of the local structure of the transport frame, combined with Figure 1-Figure 5The transport frame 80 includes a base frame 1, bearing seats, and an axial limiting device. The bearing seats are arranged in pairs and spaced longitudinally along the base frame 1. A loading slot 5 for loading columnar cargo 90 is formed between the two pairs of bearing seats. The axial limiting device includes at least two limiting members 6. The limiting members 6 include a support beam 61, a limiting seat 62, and a guide shaft 63. The limiting members 6 are adjusted by moving the limiting seats 62 relative to the support beam 61 to adjust the distance between the two limiting seats 62 arranged transversely of the base frame 1. This allows the transport frame 80 to accommodate cargo 90 of different axial lengths, thereby improving its versatility.

[0067] The chassis 1 includes two longitudinal beams 11 arranged in parallel and spaced apart from each other, and an end beam 12. The longitudinal beams 11 extend longitudinally, and the end beams 12 connect the ends of the two longitudinal beams 11. In this embodiment, the end beams 12 are provided at both ends of the longitudinal beams 11.

[0068] Specifically, the longitudinal beam 11 includes a top wall and a bottom wall spaced apart in parallel, and a side wall connected between the top and bottom walls. The top, bottom, and side walls together enclose a receiving groove that opens inward. In this embodiment, the longitudinal beam 11 has an H-shaped cross-section. In other embodiments, the longitudinal beam 11 can also be U-shaped. Alternatively, the longitudinal beam 11 can be devoid of a receiving groove; for example, the longitudinal beam 11 can have a rectangular cross-section.

[0069] The underframe 1 includes a top corner piece 13 arranged at the top of the corner. The top hole on the top corner piece 13 is used to cooperate with the crane to realize the lifting of the transport frame 80.

[0070] The chassis 1 comprises bottom corner pieces 14 arranged at the bottom of the corners. The bottom corner pieces 14 can be fixedly connected to the twist locks of railway flat cars or to the twist locks of container transport cars.

[0071] The position, size and function of the top corner pieces 13 and the bottom corner pieces 14 are the same as those of a standard container. Accordingly, the outer dimensions of the length and width of the chassis 1 are also the same as those of a standard container. Therefore, the transport frame is suitable for railway and road transport.

[0072] Furthermore, a flip-type twist lock 15 is detachably connected to the top corner fitting 13. Specifically, the flip-type twist lock 15 can rotate between a connected position located above the top corner fitting 13 and an open position located outside the longitudinal beam 11. The flip-type twist lock 15 includes an upper locking head and a lower locking head. When the flip-type twist lock 15 is in the connected position, the lower locking head is fixedly connected to the top hole of the top corner fitting 13. At this point, the upper locking head can be inserted into the bottom hole of the bottom corner fitting 14 of another transport frame 80 and connected and fixed, thereby connecting and fixing the stacked transport frames 80. When the flip-type twist lock 15 is in the open position, lifting operations can be carried out.

[0073] In some variations, when the underframe 1 is relatively light and weak, making it unsuitable for heavy-load lifting, the top corner fittings 13 are omitted from the underframe 1, and only the bottom corner fittings 14 are provided. Hooks are provided at the four corners to enable the transport frame 80 to be lifted independently. When the transport frame 80 is in use, it is first hoisted onto a vehicle such as an open car, a flat car, or a car using the hooks, and then the cargo 90 is hoisted onto the transport frame 80. When unloading the vehicle, the cargo 90 is first hoisted off the transport frame 80, and then the transport frame 80 is hoisted off the vehicle. Due to the light weight of the underframe 1, the weight of the cargo 90 can be increased accordingly, thereby reducing transportation costs.

[0074] The load bearing seats are arranged in pairs and spaced apart along the longitudinal direction of the chassis 1. A loading slot 5 for loading columnar cargo 90 is formed between the two pairs of load bearing seats. The width of the loading slot 5 is preferably gradually increased from bottom to top to adapt to the columnar cargo 90.

[0075] The position of the bearing seat on the chassis 1 can be set as needed. For example, it can be located between the two end beams 12 of the chassis 1, or at both ends of the chassis 1, or the end beams 12 can be used to form a bearing seat.

[0076] Continue reading Figure 1 and Figure 2 In this embodiment, the bearing seats include end bearing seats 2 located at both ends of the base frame 1 and fixed bearing seats 3 located between the two end bearing seats 2. The end bearing seats 2 are located at the ends of the base frame 1 and are connected to the end beams 12, or the end beams 12 are directly used as part of the end bearing seats 2. The fixed bearing seat 3 is the bearing seat located between the two end beams 12.

[0077] Figure 5 A schematic front view of a partial structure of the middle portion of the transport frame 80 is shown. Figure 6 The schematic diagram of the partial structure of the transport frame 80 is shown. Figure 4-Figure 6 A loading slot 5 is formed between the end support seat 2 and the adjacent fixed support seat 3. Thus, the transport frame 80 can simultaneously carry multiple cargoes 90. In this embodiment, there are two fixed support seats 3. In other embodiments, the number of fixed support seats 3 can be increased based on actual needs.

[0078] Specifically, the bearing seat includes a supporting beam 31 and a panel 32. The supporting beam 31 extends in the transverse direction and connects the two longitudinal beams 11. Both ends of the supporting beam 31 extend outwardly beyond the panel 32. In this embodiment, the cross-section of the supporting beam 31 is rectangular.

[0079] Panels 32 are fixed to the support beams 31. Panels 32 are tilted, and the panels 32 of two adjacent bearing seats gradually approach each other from top to bottom, collectively enclosing the loading slot 5. The portion of at least one end of at least one supporting beam 31 proximate the loading slot 5 that extends beyond the panel 32 constitutes the support beam 61 of the position-limiting member 6. Specifically, of the supporting beams 31 of the two bearing seats, either one of the supporting beams 31 may have both ends forming the support beam 61, or only one end of the supporting beam 31 may serve as the support beam 61, with the two diagonally opposite ends of the two supporting beams 31 forming the support beams 61. Alternatively, all four ends of both supporting beams 31 may constitute the support beam 61.

[0080] In this embodiment, the bearing seat includes two supporting beams 31 spaced apart in the longitudinal direction. There is a height difference between the tops of the two supporting beams 31, and the panel 32 is fixed on the two supporting beams 31. The two supporting beams 31 are respectively fixed to different vertical positions of the longitudinal beam 11 to achieve the height difference between the two. Among the supporting beams 31 of two adjacent bearing seats, the supporting beam 31 located on the inner side is lower than the supporting beam 31 located on the outer side. The inside and outside here are based on the loading slot 5, the one close to the loading slot 5 is the inside, and the one far from the loading slot 5 is the outside. In other embodiments, the difference in the tops of the two can also be achieved by using supporting beams 31 of different heights. When the bearing seat is located at the end bearing seat, the bearing seat includes a supporting beam, and the end beam 12 constitutes the supporting beam 31 located on the outer side of the end bearing seat. There is a height difference between the top of the supporting beam and the top of the end beam, and the panel is fixed on the supporting beam and the end beam.

[0081] Among them, in two adjacent loading slots 5, two bearing seats that are adjacent to each other and do not constitute a loading slot 5 are arranged in a back-to-back manner. At this time, a connecting structure can also be provided between the two bearing seats to increase the connection strength between the two bearing seats. For example, the two bearing seats can be connected by a plate. Each bearing seat includes two panels 32 spaced apart along the transverse direction, and the two panels 32 are symmetrically arranged about the center line of the chassis 1. The number of panels 32 of each bearing seat can also be three, four or other numbers, and multiple panels 32 are spaced apart along the transverse direction. With the above design, the weight is reduced while ensuring the supporting strength. In other embodiments, the panel 32 can also be continuous in the transverse direction and be a whole piece.

[0082] The support base also includes a web disposed below the panel 32, which is mounted on the support beam 31. That is, the panel 32 is supported on the support beam 31 by the web. Furthermore, the support base includes a movable support base 4. One side of the movable support base 4 is the fixed support base 3 or the end support base 2. The movable support base 4 can move longitudinally along the base frame 1 to adjust the distance between it and the fixed support base 3 or the end support base 2. By adjusting the distance between the movable support base 4 and the fixed support base 3 or the end support base 2, the size of the loading slot 5 can be adjusted, allowing the transport frame 80 to accommodate cargo 90 of varying outer diameters.

[0083] See Figure 4 In this embodiment, the transport seat frame 80 includes two end bearing seats 2, four fixed bearing seats 3 and four movable bearing seats 4, that is, it includes five pairs of bearing seats, forming five loading slots 5. Among them, the order in which the above-mentioned bearing seats are arranged in the longitudinal direction is: end bearing seat 2, two fixed bearing seats 3, four movable bearing seats 4, two fixed bearing seats 3 and end bearing seat 2. That is, the number of end bearing seats 2 is an even number, and they are arranged symmetrically about the center of the base frame 1. The number of fixed bearing seats 3 is an even number, and they are arranged symmetrically about the center of the base frame 1. The number of movable bearing seats 4 is an even number, and they are arranged symmetrically about the center of the base frame 1. In other embodiments, only the end bearing seats 2 and the movable bearing seats 4 can be set as needed. For example, two movable bearing seats 4 are set between the two end bearing seats 2. Only fixed bearing seats 3 and movable bearing seats 4 can also be set. The specific setting is based on actual needs.

[0084] Combine Figure 1 and Figure 2 The movable support 4 includes a connecting beam 41 extending in a transverse direction, a pair of mounting beams 42 disposed on opposite sides of the connecting beam, and supporting members 43 correspondingly disposed on the two mounting beams 42. The mounting beams 42 extend in a longitudinal direction, with at least two mounting beams 42 disposed in a transversely spaced relationship on the same side of the connecting beam 41. The supporting member 43 includes two interconnected supporting plates 431 and a slide 432 connecting the two supporting plates 431. The slide 432 is disposed horizontally, and the supporting plates 431 are inclined relative to the slide 432. The slide 432 is movable relative to the mounting beam 42.

[0085] The mounting beam 42 is provided with a longitudinally extending chute. The movable support 4 includes a locking member, which comprises a locking rod 433 and a locking block 434 threadedly connected to the locking rod 433. The locking rod 433 passes through the slide 432 and is fixedly connected to the slide 432. The locking rod 433 slidably engages the chute. The locking block 434 has a transverse dimension greater than that of the chute and is located below the chute. In this embodiment, the locking rod 433 can be a bolt, and the locking block 434 can be a nut.

[0086] A stop bar 44 is provided on the mounting beam 42 . The stop bar 44 is spaced apart and arranged on one side of the slide groove close to the loading groove 5 formed by the movable bearing seat. The stop bar 44 extends in the transverse direction to stop the slide plate 432 .

[0087] When two movable supporting seats 4 appear simultaneously and are connected, and the two are arranged back to back, they are arranged in the order of the blocking bar 44 , the sliding groove, the sliding groove and the blocking bar 44 .

[0088] By adjusting the position of the mobile support 4, different quantities of goods 90 can be loaded. For example, the mobile support 4 close to the fixed support 3 moves towards the adjacent fixed support 3, and the loading slots 5 formed by the two paired mobile support 4 are loaded with goods 90, while the loading slots 5 formed by the fixed support 3 and the adjacent mobile support 4 are empty. Figure 7 Alternatively, the mobile support bases 4 close to the fixed support base 3 move in a direction away from the adjacent fixed support base 3, and the loading slots 5 formed by the fixed support base 3 and the adjacent mobile support base 4 are loaded with goods 90, while the loading slots 5 between the two paired mobile support bases 4 in the middle are empty, as shown in FIG. Figure 8 shown.

[0089] The axial limiting device includes at least two limiting members 6. At least one limiting member 6 is provided at each lateral end of the loading slot 5 along the chassis 1, for respectively contacting the axial ends of the cargo 90. Exemplarily, there are two limiting members 6, each corresponding to a single load-bearing seat, i.e., located in the same longitudinal direction. Alternatively, the two limiting members 6 at each end of the loading slot 5 correspond to a single load-bearing seat, i.e., located diagonally. Alternatively, there are four limiting members 6, each provided at each lateral end of each load-bearing seat.

[0090] Figure 9 Schematic diagram of the structure of the limiting member 6 is shown. Figure 10 Shows a schematic front view of the limiting seat 62, Figure 11 The figure shows a schematic diagram of a front cross-section of one embodiment of the support beam of the present invention. Figure 9 、 Figure 10 and Figure 11 The limiting member 6 includes a support beam 61, a limiting seat 62 and a guide shaft 63. The support beam 61 is fixedly connected to the base frame 1 and extends in the transverse direction. A plurality of limiting holes 613 are provided on the support beam 61 at intervals in the transverse direction of the base frame 1.

[0091] Preferably, the support beam 61 includes a first support surface 611 and a second support surface 612 that are perpendicular to each other. The first support surface 611 and the second support surface 612 are both inclined relative to the horizontal direction. The upper surface of the top wall of the support beam 61 constitutes the first support surface 611.

[0092] The limiting hole 613 is provided on the first supporting surface 611 . That is, the limiting hole 613 is provided on the top wall of the supporting beam 61 .

[0093] Specifically, the limiting hole 613 includes a communicating through portion 6131 and a limiting portion 6132, which are arranged in sequence along the longitudinal direction. Since the first support surface 611 is inclined relative to the horizontal direction, the limiting hole 613 is also inclined relative to the horizontal direction.

[0094] In this embodiment, the limiting hole 613 is gourd-shaped, and the larger portion is the through portion 6131 , which is located at the top and close to the second supporting surface 612 .

[0095] The support beam 61 is provided with a plurality of mounting holes 614. Specifically, the mounting holes 614 are provided on the second support surface 612. The mounting holes 614 are provided in a one-to-one correspondence with the plurality of limiting holes 613. The mounting holes 614 and the corresponding limiting holes 613 are spaced apart along the longitudinal direction of the base frame 1. In this embodiment, the mounting holes 614 are circular holes.

[0096] A line connecting the center of the through portion 6131 of the limiting hole 613 and the center of the limiting portion 6132 is parallel to the axis of the mounting hole 614 .

[0097] Among them, the support beam 61 can be made of square tube steel, such as Figure 11 At this time, the support beam 61 can be the supporting beam 31 of the bearing seat. Directly using the two ends of the supporting beam 31 as the support beam 61 simplifies the structure, saves materials and reduces costs.

[0098] The support beam 61 can also be made of a bent piece, such as Figure 12 At this time, the two ends of the support beam 61 are connected to the longitudinal beam 11 and the installation beam 42 respectively.

[0099] When the support beam 61 is a bent part, the support beam 61 also includes a first flange arranged at the bottom of the first support surface 611 and a second flange arranged at the bottom of the second support surface 612. The first flange and the second flange both extend in the horizontal direction and are arranged opposite to each other.

[0100] Regardless of whether the support beam 61 is a bent part or a square tube steel, the bearing seat further includes a reinforcement block. In this case, the support beam 61 is connected to the top surface of the supporting beam or is spaced above the supporting beam.

[0101] The two ends of the support beam 61 may be connected to the longitudinal beam 11 and the web, or the two ends of the support beam 61 may be connected to the longitudinal beam 11 and the reinforcement block, respectively.

[0102] See Figure 10A downwardly protruding stop pin 625 is provided at the bottom of the stop seat 62. The stop pin 625 comprises a stop rod 6251 fixed to the bottom of the stop seat 62 and an end head 6252 disposed at the bottom of the stop rod 6251. The end head 6252 can pass through the passage 6131 but cannot pass through the stop portion 6132. When the end head 6252 is located below the stop portion, the top wall of the support beam 61 is located in the gap between the bottom of the stop seat 62 and the end head 6252, thereby securing the stop seat 62 relative to the support beam 61.

[0103] Continue reading Figure 9 and Figure 10 The limiting seat 62 includes a first base plate 621, a baffle 623 located laterally inside the first base plate 621, a second base plate 622, and two side plates 624 located on the second base plate 622 and spaced apart laterally. The first base plate 621 and the second base plate 622 are sequentially arranged along the longitudinal direction of the chassis 1.

[0104] Preferably, the first substrate 621 and the second substrate 622 are perpendicular to each other and are both tilted relative to the horizontal direction. The first substrate 621 is attached to the first support surface 611, and the second substrate 622 is attached to the second support surface 612. The first substrate 621 and the second substrate 622 are preferably integrally formed.

[0105] The limiting holes 613 and mounting holes 614 are respectively arranged on the mutually perpendicular first support surface 611 and second support surface 612, so that the limiting holes 613 and mounting holes 614 are not on the same cross-section. This reduces the effect of the limiting holes 613 and mounting holes 614 on the strength of the support beam 61. By not arranging the limiting holes 613 and mounting holes 614 on the same surface, the cross-sectional dimensions of the support beam 61 can be reduced, saving material.

[0106] A stop pin 625 is provided below the first base plate 621. A positioning pin 626 is provided at the bottom of the second base plate 622. The positioning pin 626 and the stop pin 625 are spaced apart longitudinally along the chassis 1. The positioning pin 626 can be inserted into the mounting hole 614. In this embodiment, the cross-section of the positioning pin 626 is circular. In other embodiments, the shapes of the mounting hole 614 and the positioning pin 626 can be other, depending on actual needs.

[0107] The baffle 623 is disposed on the top of the first substrate 621 , and the inner surface of the baffle 623 constitutes an abutting surface.

[0108] Preferably, ribs 627 are further provided at opposite ends of the baffle 623. The ribs 627 are longitudinally spaced apart and arranged on the top of the first substrate 621. In this embodiment, the baffle 623 and the two ribs 627 together form a structure with a U-shaped cross section.

[0109] Each side plate 624 is provided with a through hole 6241. Specifically, the through hole 6241 comprises a first portion 6246 and a second portion 6247, which are perpendicular and interconnected. The guide shaft 63 is inserted into the through hole 6241. The first portion 6246 allows the stopper 62 to move up and down relative to the guide shaft 63, while the second portion 6247 allows the stopper 62 to move axially relative to the guide shaft 63. Specifically, the second portion 6247 is located on the side of the first portion 6246 facing away from the abutment surface. In this embodiment, the through hole 6241 is L-shaped.

[0110] A wing plate 628 is further provided between the two side plates 624. The wing plate 628 is provided on the top of the second base plate 622 and is close to the first base plate 621. In this embodiment, the two side plates 624 and the wing plate 628 together form a structure with a U-shaped cross section.

[0111] Furthermore, the length of the limiting rod 6251 between the end 6252 and the bottom of the limiting seat 62 is greater than the thickness of the top wall of the support beam 61. In other words, the distance between the first substrate 621 and the end 6252 is greater than the thickness of the top wall of the support beam 61, allowing the limiting pin 625 to move smoothly to the limiting portion 6132.

[0112] The limiting member 6 also includes a limiting plate corresponding to each limiting hole 613. The limiting plate is arranged on the support beam 61 and is located outside the limiting hole 613, and is used to abut against the limiting seat 62 inserted into the limiting hole 613. Here, the inside refers to the direction toward the center of the base frame 1, and the opposite is the outside.

[0113] In this embodiment, the limiting plate extends in the longitudinal direction.

[0114] By adding a limit plate, a 90-degree axial support force is provided to the cargo, achieving better axial limitation.

[0115] The guide shaft 63 extends laterally and is fixed relative to the chassis 1. Specifically, the outer end of the guide shaft 63 is fixedly connected to the longitudinal beam 11, and the inner end of the guide shaft 63 is fixedly connected to a web fixed to the support beam 31. The web is fixed below the panel 32. The inner end of the guide shaft 63 can also be fixedly connected to the mounting beam 42.

[0116] The following describes how to use the axial limit device.

[0117] The limiting state of the limiting seat 62 and the support beam 61 is the initial state, as shown in FIG. Figure 13 That is, the limiting pin 625 is located in the limiting portion 6132 , the positioning pin 626 is located in the mounting hole 614 , and the guide shaft 63 is located at the top end in the first portion 6246 of the through hole 6241 .

[0118] Release the connection between the limiting seat 62 and the support beam 61 at the current position: move the limiting seat 62 upward along the extension direction of the first support surface 611 of the support beam 61, and the limiting pin 625 moves from the limiting portion 6132 to the through portion 6131. ​​The positioning pin 626 is separated from the mounting hole 614. The second substrate 622 moves so that the guide shaft 63 is located at the intersection of the first portion 6246 and the second portion 6247 of the through hole 6241. Figure 14 Then, along the extension direction of the second support surface 612, the limit seat 62 is moved upward, the limit pin 625 is separated from the through portion 6131, and the second substrate 622 is moved so that the guide shaft 63 is located at the second portion 6247 of the through hole 6241 away from the end of the first substrate 621, as shown. Figure 15 As shown, the limiting seat 62 is separated from the supporting beam 61.

[0119] Adjust the position of the limiting seat 62 relative to the support beam 61: After releasing the connection between the limiting seat 62 and the support beam 61, move the limiting seat 62 along the extension direction of the guide shaft 63 until it moves to the position that needs to be adjusted.

[0120] The current connection between the stopper 62 and the support beam 61 is achieved by moving the stopper 62 downward along the extension direction of the second support surface 612, inserting the stopper pin 625 into the through portion 6131. ​​The second substrate 622 is then moved so that the guide shaft 63 is located at the intersection of the first portion 6246 and the second portion 6247 of the through hole 6241. Next, the stopper 62 is moved downward along the extension direction of the first support surface 611, moving the stopper pin 625 into the stopper portion 6132. The positioning pin 626 is then inserted into the mounting hole 614. The second substrate 622 is then moved so that the guide shaft 63 is located at the top end of the first portion 6246 of the through hole 6241. This completes the connection between the stopper 62 and the support beam 61.

[0121] When the stopper 62 is positioned away from the center of the base frame 1 and in the outermost fixed position, the stopper 62 is at least partially located within the receiving groove of the longitudinal beam 11. Therefore, the movement distance of the stopper 62 can be effectively increased, thereby increasing the axial length of the loading slot 5, allowing it to accommodate cargo 90 of greater axial lengths and improving the versatility of the transport frame 80.

[0122] When the limit seat 62 is connected to the outermost limit hole 613 and still cannot meet the axial length requirement of the cargo 90, the limit seat 62 can be flipped away from the loading slot 5 to the open state, such as Figure 16Specifically, after releasing the connection between the stopper 62 and the support beam 61, the stopper 62 preferably moves along the extension direction of the guide shaft 63, preferably close to the longitudinal beam 11. The first base plate 621 is then rotated about the axis of the guide shaft 63 away from the loading slot 5, flipping the entire stopper 62 to the outside of the second support surface 612 of the support beam 61. At this point, the cargo 90 can be axially limited by the inner surface of the longitudinal beam 11, increasing the axial length of the cargo 90 that can be loaded. The cargo 90 does not contact the stopper 62.

[0123] The limit seat 62 moves to the end of the guide shaft 63 and then flips over, or flips over and then moves to the end of the guide shaft 63, that is, when the limit seat 62 is located at the end of the guide shaft 63 in the flipped state, it is beneficial to the force on the guide shaft 63. The bumps during transportation increase the force of the gravity of the limit seat 62 on the guide shaft 63. The limit seat 62 is located at both ends of the guide shaft 63, which is beneficial to avoiding the deformation of the guide shaft 63 due to force.

[0124] In the fixed bearing seat 3, when the support beam 61 is tilted, the support beam 61 can be close to the panel 32, and the distance from the contact point between the baffle 623 and the end surface of the cargo 90 to the connection point between the stop seat 62 and the support beam 61 is close (i.e., the distance from the contact line between the outer periphery of the cargo 90 and the contact surface of the baffle 623 to the stop portion 6132 and the mounting hole 614 is close). This reduces the cantilever distance of the stop seat 62 and the torque, thereby effectively ensuring that the axial stop device can withstand the axial thrust of the cargo 90. Furthermore, the stop seat 62 can be positioned at the connection position with the support beam 61 by its own gravity, resulting in a simple structure and low cost. Furthermore, there is no need to provide an additional support beam in the fixed bearing seat 3, resulting in a simple structure and low cost.

[0125] In the mobile bearing base 4, the support beam 61 can be arranged either tilted or horizontally. Figure 17 When the support beam 61 is positioned horizontally, the axial limiter also includes a locking structure 68. This locking structure 68 is used to lock the limiter seat 62 and the support beam 61, preventing the limiter seat 62 from moving horizontally and separating from the support beam. When the support beam 61 is positioned horizontally, the axial limiter requires either first releasing the locking structure 68 from the connection between the support beam 61 and the limiter seat 62, or finally reconnecting the two using the locking structure 68.

[0126] The top of the support beam 61 does not extend beyond the top of the mounting beam 42. In other words, the top of the support beam 61 can be flush with or lower than the top of the mounting beam 42 to prevent the bottom surface of a loaded coil of smaller diameter from interfering with the top surface of the support beam 61. Therefore, whether the support beam 61 is tilted or laid flat, the distance from the abutment point to the stopper 6132 and the mounting hole 614 is substantially the same, and therefore, the stress conditions are also substantially the same.

[0127] See Figure 18 When the support beam 61 is set horizontally, the limit seat 62 can only include a limit pin 625 without a positioning pin. In this case, the limit hole on the support beam 61 is a vertical long hole, and the base plate is a U-shaped plate with an opening facing downward. The base plate is buckled on the top surface and two side surfaces of the support beam 61 to limit the longitudinal movement and horizontal rotation of the limit seat 62 along the transport frame 80. The support beam 61 extends along the transverse direction of the transport frame 80, and its two ends are respectively connected to the mounting beam 42 and the longitudinal beam 11. A plurality of limit holes are arranged on the top surface of the support beam 61 at intervals along the transverse direction of the transport frame 80, and the through portion of each limit hole is close to the mounting beam 42 relative to the limit portion. When the limit pin 625 is inserted into the through portion 6131, the base plate is buckled with the support beam 61. When the limit pin 625 is disengaged from the through portion 6131, the base plate is disengaged from the support beam 61.

[0128] See Figure 19 In one variation, the chassis 1 includes two longitudinal beams 11 and an end beam 12. The transport frame 80 includes three fixed support brackets 3. Two adjacent fixed support brackets 3 form a loading slot 5. The fixed support bracket 3 at the end without the end beam 12 forms half of the loading slot 5. A stopper 6 is provided at one end of the half loading slot 5. During use, the half loading slots 5 of the two transport frames 80 are aligned to form a loading slot 5. The loading slot 5 has a stopper 6 at each end. In this case, the two transport frames 80 are loaded with three coils to ensure that the transport vehicle is fully loaded.

[0129] Preferably, a reinforcement support structure is provided on the outside of the fixed bearing seat, and the reinforcement support structure and the fixed bearing seat 3 are arranged back to back to enhance the strength of the fixed bearing seat, thereby better loading and supporting the coiled material. In this embodiment, the reinforcement support structure adopts a mirror-symmetrical structure with the fixed bearing seat.

[0130] In this variant, a web is provided at the bottom of the panel 32, and the web is provided between the support beam 31 and the panel. Alternatively, the web can also be a connecting block, that is, the panel is supported on the support beam 31 by the connecting block.

[0131] When cargo 90 is positioned within the loading slot 5 of the transport frame 80 and axially restrained by the retaining member 6, the thrust exerted by the cargo 90 on the retaining seat 62 is primarily transmitted to the support beam 61, and then to the base frame 1, through the engagement of the retaining pin 625 with the retaining hole 613 and the engagement of the positioning pin 626 with the mounting hole 614. When the transport frame 80 is used in railway open-top car transport, the transport frame 80 is typically restrained by the reinforced seats within the open-top car. Multiple reinforced seats are spaced along the length of the open-top car, located below the inner sidewalls and projecting toward the center of the open-top car along the width of the open-top car. Railway open-top cars come in a variety of sizes, such as 60-ton, 64-ton, and 70-ton models, and the different interior lengths of these models result in different reinforcement seat positions and spacing. Longer transport frames 80 require abutment with two reinforced seats on each side to prevent movement and horizontal rotation along the length and width of the open-top car.

[0132] In order to adapt the transport frame 80 to different types of open wagons, see Figure 19 and Figure 21 The transport frame 80 further includes a first positioning assembly and a second positioning assembly spaced longitudinally on the base frame 1. The first positioning assembly includes first positioning members 71 disposed on opposite sides of the base frame 1. Specifically, the two first positioning members 71 are spaced transversely. The first positioning members 71 extend outward from the base frame 1 and are capable of moving transversely.

[0133] See Figure 20 The first positioning member 71 includes a first slider 711 and a protrusion 712 extending outward from the first slider 711. The protrusion 712 is arranged on the outer side of the first slider 711 and exposes at least part of the outer side surface of the first slider 711. The side surface of the protrusion 712 adjacent to the first slider 711 and the outer side surface of the first slider 711 jointly form a first abutting surface, which is used to abut the inner surface and side surface of the reinforcement seat in the transport vehicle.

[0134] The second positioning assembly includes second positioning members 72 located on opposite sides of the chassis 1. The two second positioning members 72 are spaced laterally apart. The second positioning members 72 extend outward from the chassis 1 and are capable of laterally moving. The second positioning members 72 include second sliders 721. The second sliders 721 extend outward from the chassis 1 and are capable of laterally moving. The outer side surfaces of the second sliders 721 are configured to abut against the inner sidewalls of the transport vehicle.

[0135] The first positioning assembly and the second positioning assembly each include a sliding sleeve 73 and a locking member 74. The sliding sleeve 73 is fixed to the base frame 1 and extends in the transverse direction. The sliding sleeve 73 is hollow inside and has an open outer end.

[0136] The first slider 711 extends laterally. The first slider 711 extends from an outer opening into the interior of the sliding sleeve 73 and is capable of sliding along the sliding sleeve 73. A plurality of first locking holes are defined laterally along the upper edge of the first slider 711. The second slider 721 extends laterally. The second slider 721 extends from an outer opening into the interior of the sliding sleeve 73 and is capable of sliding along the sliding sleeve 73. A plurality of second locking holes are defined laterally along the upper edge of the second slider 721.

[0137] The locking member 74 includes a locking seat 741 fixed to the sliding sleeve 73 and a locking rod 742 that can be raised and lowered along the locking seat 741. The locking rod 742 can extend downward and be inserted into the first locking hole. The locking rod 742 can also extend downward and be inserted into the second locking hole. Specifically, a through hole is defined in the top wall of the sliding sleeve 73 for the locking rod 742 to pass through. The locking rod 742 can pass through this through hole into the interior of the sliding sleeve 73 and then be inserted into the first or second locking hole.

[0138] That is, the locking rod 742 is selectively inserted into the first locking hole to adjust the position of the first slider 711 . The locking rod 742 is selectively inserted into the second locking hole to adjust the position of the second slider 721 .

[0139] Furthermore, a reference line is provided on the upper surface of the first slider 711. When the reference line is aligned with the outer end surface of the sliding sleeve 73, the locking rod 742 is aligned with the first locking hole, making it easy for the locking rod 742 to be inserted into the first locking hole.

[0140] Similarly, a reference line is provided on the upper surface of the second sliding block 721. When the reference line is aligned with the outer end surface of the sliding sleeve 73, the locking rod 742 is aligned with the second locking hole, making it convenient for the locking rod 742 to be inserted into the second locking hole.

[0141] The first positioning assembly abuts two adjacent side surfaces of the reinforcement seat, achieving positioning along the length and width of the gondola. The second positioning assembly abuts the sidewall of the gondola along its width. Therefore, the transport frame 80 can accommodate variations in the spacing between the reinforcement seats within a certain range without affecting the abutment of the second positioning member 72 against the sidewall of the gondola, making the transport frame 80 universally applicable.

[0142] In summary, the transport stand 80 has the following advantages:

[0143] 1. The transport frame 80 uses an axial limiting device to axially limit the cargo 90 within the loading trough 5. The two limiting members 6 of the axial limiting device are both capable of moving laterally along the base frame 1, thereby adjusting the distance between the two limiting members 6 to accommodate cargo 90 of varying axial lengths, thereby improving the versatility of the transport frame 80.

[0144] The movable, flippable and non-detachable connection between the limit seat 62 and the guide shaft 63 not only facilitates the adjustment of the limit seat 62 and prevents the limit seat 62 from being lost, but also allows the end of the cargo 90 located in the loading slot 5 to abut the inner side surface of the longitudinal beam 11 of the chassis 1 by flipping, thereby further expanding the size of the cargo 90 that can be loaded.

[0145] The entire transport stand 80 has a simple structure, is easy to install and maintain, and can be used quickly.

[0146] 2. By setting the limit seat 62 in the space outside the panel 32 and the supporting member 43, the phenomenon of the panel 32 and the supporting member 43 being too large and wasting materials caused by setting the limit seat 62 on the panel 32 and the supporting member 43 is avoided, the weight of the transport frame 80 is reduced, and materials are saved.

[0147] 3. The limiting holes 613 and mounting holes 614 are respectively arranged on the mutually perpendicular first support surface 611 and second support surface 612, and the limiting holes 613 and mounting holes 614 are not located on the same cross-section. This reduces the effect of the limiting holes 613 and mounting holes 614 on the strength of the support beam 61. By not arranging the limiting holes 613 and mounting holes 614 on the same surface, the cross-sectional dimensions of the support beam 61 can be reduced, saving material.

[0148] 4. By setting the movable bearing seat, the transport frame 80 can selectively load different quantities of goods 90 according to the diameter and weight of the goods 90.

[0149] 5. The first positioning assembly abuts against two adjacent side surfaces of the reinforcement seat to achieve positioning along the length and width of the gondola. The second positioning assembly abuts against the sidewall of the gondola along its width, and the ends of the transport frame 80 are used to limit the position, making the transport frame 80 compatible with a variety of gondola models. Furthermore, the first and second positioning assemblies feature a simple structure and minimal material requirements. The telescopic structure ensures a long travel, high strength, and easy operation of the sliders of the first and second positioning assemblies, making the transport frame 80 suitable for both rail and road transport.
