Description

Technical Field

[0001] The present invention relates to the technical field of railway transportation equipment, particularly to the technical field of railway freight cars. Specifically, it relates to a steel container rack composed of a movable end wall and a variable-position baffle. Background Art

[0002] With the development of social economy, the demand for various steels is increasing continuously. Steel products of steel enterprises need to be transported not only by railway, but also through waterway and highway transportation modes to reach customers.

[0003] In China, railways mainly use open wagons and flat cars for transportation. With the continuous development of the railway industry, the transportation mode of using open wagons and flat cars for transporting steel is gradually changing to container rack transportation. In the prior art, container rack transportation in China generally uses a fixed upper crossbeam or a movable upper crossbeam. Goods can only be placed between the two crossbeams, so it is impossible to load goods longer than the length of the container rack itself; or use a fixed baffle to transport steel. Such a baffle can only load coiled steel with a specific diameter or section steel, steel plates, etc. of a certain size.

[0004] As described above, there are the following defects in using the existing steel container rack for transportation: the existing steel container rack cannot meet the loading requirements of various steels, and its structure is likely to cause problems such as excessive vehicle dead weight and unreasonable bearing capacity distribution. Such a loading method results in great waste of transportation and directly affects the transportation cost. Summary of the Invention

[0005] In order to solve the above technical problem that the existing container rack cannot meet the loading requirements of various steels, the purpose of the present invention is to provide a steel container rack composed of a movable end wall and a variable-position baffle, which can meet the loading requirements of various section steels, steel plates, steel bars and steel coils through the combined action of the movable end wall and the variable-angle baffle, and has a good application prospect in the field of railway freight transportation.

[0006] The technical solution adopted by the present invention is as follows:

It is characterized in that: the end wall assembly is movably connected to the carrier frame body through a round pin assembly, and can realize unilateral rotation of the end wall close to 90° or complete disassembly; the baffle assembly is a variable-angle baffle assembly. One end of the baffle assembly is hinged to a hinge seat on the carrier frame through a hinge, and the other end is hinged with a strut assembly. The strut assembly supports below the baffle assembly, and by changing the hinged position of the strut assembly and the baffle assembly, the angle change of the baffle assembly is realized to meet the loading requirements of various section steels, steel plates, steel bars and steel coils.

[0008] Preferably, the carrier frame body includes end beam assemblies, column assemblies, side beam assemblies, longitudinal beams, and cross beam assemblies; among them

[0009] The end beam assemblies are arranged at both ends of the carrier frame and are rigidly connected to the side beam assemblies to form a closed frame structure;

[0013] Further preferably, as the above technical solution, the cross beam assemblies include cross beam assembly one, cross beam assembly two, cross beam assembly three, and cross beam assembly four; among them, the cross beam assembly one passes through the longitudinal beam and is fixed at the middle position of the closed frame structure, the cross beam assembly two, cross beam assembly three, and cross beam assembly four are symmetrically arranged with respect to the cross beam assembly one respectively, and are evenly distributed on both sides of the cross beam assembly one; both ends of the cross beam assembly one, cross beam assembly two, cross beam assembly three, and cross beam assembly four are rigidly connected to the side beam assemblies respectively.

[0014] Further preferably, as the above technical solution, the end beam assemblies include end beams, end beam strengthening columns, end strengthening iron one, and end strengthening iron two.

[0016] Further preferably, as the above technical solution, the column assemblies include columns, sealing plates one, strengthening beams, and pin sockets. The columns and strengthening beams are of an inwardly buckled structure and are rigidly connected into a columnar structure through their inwardly buckled ends. The pin sockets are evenly arranged on the strengthening beams. The sealing plates one are fixed at the tops of the columns for fixing with the top corner fittings of the container.

[0017] As a further preference of the above technical solution, the carrier frame body further includes support seat assembly one and support seat assembly two, and the support seat assembly one and the support seat assembly two are evenly distributed inside the side beam assembly.

[0018] As a preference of this technical solution, the end wall assembly includes an end plate, an upper end beam, an end post assembly, and a latch assembly. The end plate is arranged at the end of the container frame; a plurality of latch seats are arranged on the container frame corresponding to both sides of the end plate; the end post assembly is fixed on both sides of the end plate, and the end post assembly is detachably connected to the latch seat through the latch assembly; the upper end beam is fixed at the upper and lower ends of the end plate, so that the end beam and the end post assembly form a rectangular frame structure around the end plate.

[0019] The design principle of the end wall assembly of this technical solution is as follows: aiming at the technical problem that the existing end wall structure of the container frame during transportation cannot load goods exceeding the length of the container frame itself, the end wall structure is improved. An end post assembly with high structural strength is designed on both sides of the end plate, and the end post assembly is detachably connected to the latch seat on the corresponding container frame through the latch assembly, thus forming a detachable movable end wall structure. This end wall structure can rotate unilaterally by nearly 90° around one side of any end post assembly, and at the same time, the end wall structure can also be completely disassembled to load goods exceeding the length of the container frame itself, meeting the loading requirements of various goods.

The bolt passes through the end post assembly and is rigidly connected to the end post assembly, so that the round pin passes through the bolt to achieve the detachable connection between the end post assembly and the container frame, and the end wall can rotate unilaterally by nearly 90°.

[0021] As a further preference of the above technical solution, three groups of bolts are evenly arranged on one side of each group of end post assemblies, which is convenient for inserting and pulling out the round pin.

A hinge is provided on one side of the frame assembly and is hinged to a hinge seat on the cross beam of the carrier frame through the hinge. The baffle assembly is laid flat and fixed on the frame assembly for carrying goods. The support base is fixed to the bottom of the frame assembly and is provided on the other side of the frame assembly relative to the hinge. One end of the strut assembly is hinged to the support base through a round pin. The baffle assembly is configured to have a flat state and a folded state. When the baffle assembly is in the flat state, the other end of the strut assembly is hinged to the hinge. When the baffle assembly is in the folded state, the other end of the strut assembly is hinged to the cross beam of the carrier frame through a pin bolt, so that there is a folding angle between the baffle assembly and the carrier frame, realizing the angle change of the baffle assembly.

[0025] As a further optimization of the above technical solution, the hinge is of a U-shaped structure, and a first hinge hole and a first hinge hole are arranged at both ends of the U-shaped structure. The first hinge hole is used to connect the cross beam of the carrier frame, and the second hinge hole is used to connect the strut assembly. When one end of the strut assembly is hinged to the hinge, the baffle assembly constitutes a flat state. When one end of the strut assembly is hinged to the cross beam of the carrier frame assembly, a certain angle is formed between the baffle assembly and the carrier frame body.

[0026] As a further optimization of the above technical solution, the baffle assembly includes a baffle, a backing plate, and a baffle support base. The backing plate is fixed to the bottom of the baffle, and the baffle support base is fixed to the bottom of the frame assembly. As an optimization, a wear-resistant rubber is laid flat on the baffle, and the wear-resistant rubber is fastened to the baffle and the backing plate through bolts. As a further optimization, the baffle support base includes a U-shaped baffle support and a rib plate A fixed inside the U-shaped baffle support. The U-shaped baffle support is fixed to the bottom of the frame assembly so that when the baffle assembly is in the flat state, the U-shaped baffle support can support the baffle assembly.

[0027] As a further optimization of the above technical solution, the frame assembly includes frame A, frame B, and frame C. Frame A, frame B, and frame C are sequentially connected and fixed to form a square frame structure. As an optimization, frame B extends vertically along both ends of frame C. The frame assembly further includes columns, sealing plate three, and rib plate B. The columns are evenly arranged and fixed inside the frame structure. The sealing plate three is fixed to the end of frame B to play a role in sealing and waterproofing. The rib plate B is of a triangular structure, and its two right-angled sides are respectively fixed to the extended section of frame B and frame C to play a role in strengthening the strength of the frame assembly.

[0028] As a further optimization of the above technical solution, the strut assembly includes a strut, strut heads located at both ends of the strut, a round pin two passing through the strut head in a direction perpendicular to one of the strut heads, and a pin bolt passing through the strut head in a direction perpendicular to the other strut head. One end of the round pin two passing through the strut head is fastened by a pin, and the pin bolt passing through the other end of the strut head is fastened by a nut, a washer and a pin.

[0029] As described above, the present invention has at least the following beneficial effects:

[0030] 1. The steel container frame of the present invention achieves the loading requirements for various types of steel sections, steel plates, steel bars and steel coils through the combined action of the movable end wall and the variable-angle baffle. The structural design of the movable end wall can effectively solve the technical problem that the existing container frame transportation end wall structure cannot load goods longer than the length of the container frame itself. The variable-angle baffle assembly can change the position where the strut assembly is hinged to the baffle assembly, realizing the angle change of the baffle assembly, and then being applicable to loading coil steels with various diameters and various forms of steel sections, steel plates, steel bars, etc., meeting the loading requirements for various goods, and having good application prospects and popularization and use value in the technical field of railway transportation equipment.

[0031] 2. The load-bearing frame body of the steel container frame of the present invention adopts a rigid connection between the end beam assembly and the side beam assembly to form a closed frame structure, which can effectively reduce the vehicle self-weight, and reasonably distribute the vehicle stress, effectively enhancing the vehicle load-bearing capacity; and the cross beam assembly is uniformly arranged by passing through the longitudinal beam, which can effectively improve the structural stability of the overall load-bearing frame and is beneficial to improving the vehicle loading safety.

[0032] 3. The structural design of the end beam assembly, side beam assembly, column assembly, etc. in the load-bearing frame body of the steel container frame of the present invention combined with the support seat assembly one and the support seat assembly two can make the entire load-bearing frame have better structural stability, effectively improve the vehicle's ability to bear concentrated loads, and effectively improve the vehicle transportation efficiency and utilization rate.

[0033] 4. The end wall assembly of the steel container frame of the present invention is hinged to the pin seat on the load-bearing frame through the round pin assembly and the door bolt, realizing that the end wall rotates unilaterally close to 90°, meeting the loading requirements for various goods; at the same time, the design of the cross belt assembly is on the one hand to strengthen the structural strength of the end plate, which is beneficial to improving the vehicle loading safety; on the other hand, combined with the design that the door bolt passes through the end column assembly and the cross belt assembly for rigid connection, it can further strengthen the connection stability between the door bolt and the end column assembly.

[0034] 5. In the variable-angle baffle assembly of the steel container rack of the present invention, the hinge is an integral casting, which can not only reduce costs but also increase the structural connection strength, ensuring a better support effect when the baffle assembly is in a flat state and facilitating the switching of the baffle assembly angle. This structural design is ingenious and reasonable. Moreover, the combination design of structures such as the baffle assembly, baffle support seat, and frame assembly in the variable-angle baffle assembly can make the entire variable-angle baffle assembly have better structural stability, effectively improving its load-bearing capacity for goods and effectively enhancing the vehicle transportation efficiency and utilization rate.

[0035] In summary, the steel container rack of the present invention adopts a lightweight design, which can effectively reduce its own weight and has beneficial effects such as simple manufacturing process, low manufacturing cost, and convenient maintenance and repair. It solves the technical problem that the existing container racks are difficult to meet the requirements of loading coils of various diameters and various forms of profiled steel, steel plates, steel bars, etc. in a simple structural design manner. It can meet the loading requirements of various profiled steels, steel plates, steel bars, and steel coils, and can meet the loading requirements without disassembling the fixed bearing rack structure, with simple and convenient operation and saving transportation energy costs.

[0080] Embodiment 3

[0081] Embodiment 3 is basically the same as Embodiment 1, and the difference is that: this embodiment provides a steel container frame with a movable end wall and a variable-position baffle, as shown in Figure 15 and 16 shown. To meet the loading requirements of various goods, the end wall assembly includes end plates 16, upper end beams 17, end post assemblies 19, and pin assemblies. The end plates 16 in this embodiment are rectangular and are arranged at the ends of the container frame, and several pin seats are provided on the container frame corresponding to both sides of the end plates 16. The end post assemblies 19 are fixed on both sides of the end plates 16, and the end post assemblies 19 are detachably connected to the pin seats 22 on the container frame through the pin assemblies. The upper end beams 17 are fixed at the upper and lower ends of the end plates 16, so that the upper end beams 17 and the end post assemblies 19 form a rectangular frame structure around the end plates 16.

[0082] The detachable movable end wall of this embodiment further includes a crossband assembly 20. The crossband assembly 20 is fixed in the box-shaped frame structure and rigidly connected to the end plate 16. In this embodiment, the design purpose of the crossband assembly 20 is to strengthen the structural strength of the end plate 16 to ensure the stability of the end wall structure. Further, the crossband assembly 20 includes multiple crossbands 20.1 arranged in parallel with the upper end beam 17 and partitions 20.2 built inside the crossbands 20.1. Taking six crossbands 20.1 provided in this embodiment as an example, the six crossbands 20.1 are evenly arranged on the end plate 16 along the height direction of the end plate 16 so that the end plate 16 can be evenly stressed when carrying goods.

[0083] To achieve the detachable connection between the end post assembly 19 and the pin socket on the container frame, the pin assembly provided in this embodiment includes a bolt 18 and a round pin 21 arranged on the end post assembly 19. The bolt 18 passes through the end post assembly 19 and is rigidly connected to the end post assembly 19 so that the round pin 21 passes through the bolt 18 to achieve the detachable connection between the end post assembly 19 and the container frame; the structure design of the pin assembly in this embodiment is simple and can effectively ensure the connection stability between the bolt 18 and the end post assembly 19.

[0084] Specifically, three bolts 18 are evenly arranged on the end post assembly 19 on each side of the end plate 16. Correspondingly, three pin sockets 22 are respectively provided on the container frames on both sides of the corresponding end plate 16. The bolts 18 and the pin sockets 22 are in one-to-one correspondence to facilitate the insertion and extraction of the round pin 21.

[0085] As Figure 17 shown, the end post assembly 19 provided in this embodiment includes an end post 19.1 and a second sealing plate 19.2. The second sealing plate 19.2 is fixed at both ends of the end post 19.1 to play a role in sealing and waterproofing; preferably, the end post assembly 19 further includes a first lifting ring 19.3. The first lifting ring 19.3 passes through the second sealing plate 19.2 and is fixedly connected to it to facilitate bundling when installing and disassembling the end wall.

[0086] As Figure 19 shown, the round pin 21 provided in this embodiment includes a smooth round pin 21.2, an elastic pin 21.3 provided at the bottom of the smooth round pin 21.2, and a hanging plate 21.1 provided at the top of the smooth round pin 21.2. The hanging plate 21.1 is fixed on the smooth round pin 21.2 to facilitate the insertion and extraction of the pin assembly.

[0087] As described above, in view of the technical problem that the existing end wall structure of the container rack transportation end cannot load goods exceeding the length of the container rack itself, the end wall structure is improved. On both sides of the end plate 16, end column assemblies 19 with high structural strength are designed. The bolt 18 passes through the end column assemblies 19 and is rigidly connected to the end column assemblies 19. The round pin 21 passes through the bolt 18 and the socket on the corresponding container rack to achieve detachable connection. In this way, a detachable movable end wall structure is formed. This end wall structure can rotate unilaterally by nearly 90° around one side of any end column assembly 19. At the same time, the end wall structure can also be completely disassembled to load goods exceeding the length of the container rack itself, which is convenient for the installation and disassembly of the end wall and realizes the unilateral rotation of the end wall by nearly 90°, meeting the loading requirements of various goods.

[0088] Embodiment 4

[0089] Embodiment 4 is basically the same as Embodiment 3, and the difference lies in that: as a preferred solution of Embodiment 3, in combination with Figure 15 and Figure 18 As shown, in this embodiment, a crossband assembly 20 rigidly connected to the end plate 16 is provided in the box-shaped frame structure, so that the bolt 18 passes through the end column assembly 19 and the crossband assembly 20 and is rigidly connected. Therefore, the design purpose of the crossband assembly 20 in this embodiment is not only to strengthen the structural strength of the end plate 16, but also to further strengthen the connection stability between the bolt 18 and the end column assembly 19. This design is ingenious and reasonable.

[0090] Specifically, the crossband assembly 20 includes a crossband 20.1 corresponding to the bolt 18 and a partition 20.2 built inside the crossband 20.1. An installation hole for the bolt 18 to pass through is provided on the partition 20.2, so that the bolt 18 passes through the partition 20.2 and is fixed to it; this structural design and manufacturing process are simple, which can effectively overcome the drawback of unstable connection of the detachable movable end wall and ensure that the overall structure is designed in a lightweight manner, reducing the self-weight of the end wall structure.

[0091] In summary, the design of the crossband assembly 20 of the detachable movable end wall in this embodiment is on the one hand to strengthen the structural strength of the end plate 16, which is beneficial to improving the loading safety of the vehicle; on the other hand, combined with the design that the bolt 18 passes through the end column assembly 19 and the crossband assembly 20 and is rigidly connected, it can further strengthen the connection stability between the bolt 18 and the end column assembly 19; at the same time, the design of the pin assembly and the lifting lugs on the end column assembly 19 facilitates the installation and disassembly of the end wall structure. The detachable movable end wall in this embodiment has a simple manufacturing process, low manufacturing cost, and the detachable movable end wall as a whole is designed in a lightweight manner, reducing its own weight, and has good application prospects and popularization value in the technical field of railway transportation equipment.

[0092] Embodiment 5

[0093] Example 5 is basically the same as Example 1, except that: This example provides a steel container rack composed of a movable end wall and a variable-position baffle, as Figure 20 and 21 shown. To meet the requirements of loading coils of various diameters and various forms of section steel, sheet materials, steel bars, etc., the variable-angle baffle assembly provided in this example includes a frame assembly 28, a baffle assembly, a support base 24, and at least one strut assembly 30. Specifically, a hinge 29 is provided on one side of the frame assembly 28 and is hinged to a hinge seat 33 on the upper crossbeam assembly 32 of the carrier through the hinge 29, and the baffle assembly is laid flat and fixed on the frame assembly 28 for carrying goods. The support base 24 is fixed to the bottom of the frame assembly 28, and the support base 24 is provided on the side of the frame assembly 28 opposite to the hinge 29. The number of strut assemblies 30 is determined according to the goods carried and the length of the baffle assembly along the crossbeam direction. In this example, taking the provision of three strut assemblies 30 as an example, the three strut assemblies 30 are arranged in parallel along the length direction of the crossbeam. One end of the strut assembly 30 is hinged to the support base 24, and the baffle assembly is configured to have a flat state and a folded state. When the baffle assembly is in the flat state, the other end of the strut assembly 30 is hinged to the hinge seat 33; as Figure 21 shown. When the baffle assembly is in the folded state, the other end of the strut assembly 30 is hinged to the carrier crossbeam, so that there is a folding angle between the baffle assembly and the carrier. Preferably, when the baffle assembly is in the folded state, one end of the strut assembly 30 is fastened to the support base 24 through a round pin 30.3, and the other end is fastened to the carrier crossbeam through a pin bolt 30.6. By changing the position where the strut assembly 30 is hinged to the baffle assembly, the angle change of the baffle assembly is realized, so as to be applicable to loading coils of various diameters and various forms of section steel, sheet materials, steel bars, etc., and meet the loading requirements of various goods.

[0094] To facilitate the baffle assembly to be configured in a flat state, the hinge 29 provided in this example has a U-shaped structure and is made of an integral casting. The first hinge hole and the first hinge hole are arranged at both ends of the U-shaped structure. The first hinge hole is used to connect the carrier crossbeam, and the second hinge hole is used to connect the strut assembly 30; in this example, the hinge 29 is made of an integral casting, which can effectively reduce costs and increase the strength of the baffle assembly in the flat state.

[0095] Specifically, the baffle assembly provided in this embodiment includes a baffle 26, a backing plate 23, a hinge seat 33 and a baffle support seat 31. The backing plate 23 is fixed to the bottom of the baffle 26, and the hinge seat 33 and the baffle support seat 31 are fixed to the bottom of the frame assembly 28. The design of the backing plate 23 can effectively enhance the structural strength of the baffle 26, and the design of the hinge seat 33 and the baffle support seat 31 can effectively play a supporting role when the baffle assembly is in a flat state. As a preference of this embodiment, a wear-resistant rubber 27 is laid flat on the baffle 26, and the wear-resistant rubber 27 is fastened to the baffle 26 and the backing plate 23 by bolts. The design of the wear-resistant rubber 27 can effectively enhance the friction between the goods and the bearing surface of the baffle assembly, making the transportation process more stable. At the same time, the wear-resistant rubber 27 can play a role of flexible buffering to prevent the surface of the goods from being damaged. The backing plate 23 not only enhances the structural stability of the baffle 26 itself, but also plays a role in stabilizing the wear-resistant rubber 27, making the fixation of the wear-resistant rubber 27 more reliable.

[0096] Considering the safety of transportation, a second lifting ring 25 is further provided on the frame assembly 28 on the side away from the hinge 29. The second lifting ring 25 extends along the laying direction of the baffle assembly and passes through and is fixed to one side of the frame assembly 28. In this way, the loaded goods can be hoisted onto the baffle 26 by tightening a rope through the second lifting ring 25 to ensure the safety of its transportation.

[0097] To enhance the structural strength of the baffle assembly, as Figure 23 shown, the hinge seat 33 and the baffle support seat 31 provided in this embodiment include a U-shaped baffle support 31.1 and a rib plate A31.2 fixed inside the U-shaped baffle support 31.1. The U-shaped baffle support 31.1 is fixed to the bottom of the frame assembly 28, so that when the baffle assembly is in a flat state, the U-shaped baffle support 31.1 can support the baffle assembly.

[0098] As Figure 24 shown, the strut assembly 30 provided in this embodiment includes a strut 30.2, strut heads 30.1 at both ends of the strut 30.2, a round pin two 30.7 passing through perpendicularly to one strut head 30.1, and a pin bolt 30.6 passing through perpendicularly to the other strut head 30.1. One end of the round pin two 30.7 passing through the strut head 30.1 is fastened by a pin, and the pin bolt 30.6 passing through the other strut head 30.1 is fastened by a nut 30.4, a washer 30.5 and a pin. With the above structure, it is convenient to form a stable hinge between the strut assembly 30 and the support seat 24, which is convenient for disassembly and at the same time convenient for the strut assembly 30 to be switched and installed between the hinge seat 33 and the crossbeam of the carrier.

[0099] The above variable-angle baffle assembly adopts a lightweight design, which can effectively reduce its own weight and has beneficial effects such as simple manufacturing process, low manufacturing cost, and convenient maintenance. It solves the technical problem that the existing fixed baffle 264 is difficult to meet the requirements of loading coils of various diameters and various forms of section steel, sheet metal, steel bars, etc. in a simple structural design method.

[0100] Embodiment Six

[0101] Embodiment Six is basically the same as Embodiment Five, and the difference lies in that: as a preferred solution of Embodiment Four, this embodiment provides a variable-angle baffle assembly. Considering the stability of the overall structure, as Figure 22 shown, the frame assembly 28 provided in this embodiment includes frame A 28.1, frame B 28.2, and frame C 28.3. The frame A 28.1, frame B 28.2, and frame C 28.3 are sequentially connected and fixed to form a square frame structure. In this way, the frame assembly 28 has good structural stability, which is beneficial to carrying goods and also beneficial to the fixed installation of the baffle assembly; at the same time, frame B 28.2 extends along the vertical direction at both ends of frame C 28.3; to reinforce the structural strength of the frame assembly 28, the frame assembly 28 provided in this embodiment further includes struts 28.5, sealing plate three 28.6, and rib plate B 28.4. The struts 28.5 are uniformly arranged and fixed inside the frame structure; the sealing plate three 28.6 is fixed at the end of frame B 28.2 to play a role in sealing and waterproofing; the rib plate B 28.4 is in a triangular structure, and its two right-angled sides are respectively fixed to the extended section of frame B 28.2 and frame C 28.3 to play a role in strengthening the strength of the frame assembly 28.

[0102] Thus, the combination design of the baffle assembly, hinge seat 33, baffle support seat 31, and frame assembly 28 in the variable-angle baffle assembly provided in this embodiment can make the entire variable-angle baffle assembly have good structural stability, effectively improve its load-bearing capacity for goods, and effectively improve the vehicle transportation efficiency and utilization rate.

[0103] In summary, in this embodiment, the variable-angle baffle assembly is hinged to the support seat 24 at the bottom of the strut assembly and the frame assembly. By changing the hinged position between the strut assembly and the baffle assembly, the angle change of the baffle assembly can be realized, which can be applied to loading coils of various diameters and various forms of section steel, plates, steel bars, etc., meeting the loading requirements of various goods. At the same time, to facilitate the baffle assembly to be configured in a flat state, the hinge provided in this embodiment adopts an integral casting, which can effectively reduce costs and increase the strength of the baffle assembly in the flat state to ensure that the baffle assembly has a good supporting effect when in the flat state, facilitating the switching of the angle of the baffle assembly. The structural design is ingenious and reasonable. As described above, the variable-angle baffle assembly provided in this embodiment can meet the loading requirements without disassembling the fixed carrier structure, is simple and convenient to operate, saves transportation energy costs, has good application prospects and popularization value in the technical field of railway transportation equipment, and is suitable for popularization and application.
