[0036] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0037] Example 1

[0038] Figure 1 This is a top view of the central underframe of a railway concave-bottom flatcar. Figure 2 This is a top view of the body of a railway flatcar with a concave bottom. Figure 3 This is the front view of the body of a railway concave-bottom flatcar.

[0039] refer to Figures 1 to 3 The railway concave-bottom flatcar body assembled by this utility model includes a central base frame 100, two end base frames 200, and two side walls 300.

[0040] The length of the central underframe 100 is the same as the length of the railway concave-bottom flatcar body. The central underframe 100 is used to provide support for the flat surface of the railway concave-bottom flatcar.

[0041] The two end base frames 200 are welded to both ends of the middle base frame 100, respectively.

[0042] The two side walls 300 are respectively welded to the two long sides of the central base frame 100, and the two side walls 300 extend beyond the two ends of the central base frame 100 along the length direction of the railway concave-bottom flatcar body, and the extended part is welded to the end base frame 200.

[0043] refer to Figure 1 The central base frame 100 includes four lower side beams 102 extending along its length, multiple crossbeams 103 extending along the width direction of the central base frame 100 (perpendicular to the length direction of the central base frame 100), four end casting reinforcement seats 101 located at the four corners of the central base frame 100, and two central casting reinforcement seats 104.

[0044] One of the central casting reinforcement seats 104 connects to two lower side beams 102 to form one long side of the central base frame 100, and the other central casting reinforcement seat 104 connects to the other two lower side beams 102 to form the other long side of the central base frame 100.

[0045] The lower side beam 102, at its end furthest from the central casting reinforcement seat 104, is connected to the end casting reinforcement seat 101. A crossbeam 103 connects between two opposing end base frame casting reinforcement seats 101 along the width direction of the central base frame 100. A crossbeam 103 connects between the two central casting reinforcement seats 104. A crossbeam 103 connects between two opposing lower side beams 102 along the width direction of the central base frame 100. This results in the central base frame 100 having an overall rectangular grid structure.

[0046] Both the middle casting reinforcing seat 104 and the end casting reinforcing seat 101 are castings, serving as mechanical reinforcements. This invention does not limit the shape or size of either component.

[0047] refer to Figure 4 and combined Figure 1 Under the condition of meeting the assembly accuracy, the lower surfaces of the middle casting reinforcement seat 104 and the end casting reinforcement seat 101 are horizontal planes and the height is the expected height; the outer surfaces of the middle casting reinforcement seat 104 and the end casting reinforcement seat 101 are vertical planes and parallel to the length direction of the middle base frame 100, and the outer surfaces of the middle casting reinforcement seat 104 and the end casting reinforcement seat 101 should be in the expected position.

[0048] In Example 1, the central base frame support device supports the central base frame at the positions of the central casting reinforcement seat 104 and the end casting reinforcement seat 101.

[0049] Figure 4 This is a front view of a single central underframe support component. Figure 5 This is a top view of a single central base support component. Figure 6 This is a top view of the central underframe support device.

[0050] refer to Figures 4 to 6 Example 1 provides a central underframe support device for supporting the central underframe 100 of a railway concave-bottom flatcar body. The central underframe support device includes two rows of central underframe support members 5. In this example, each row of central underframe support members 5 contains four members. Two central underframe support members 5 located at the end positions in the same row are respectively positioned below the end casting reinforcement seats 101 at the corner positions of the central underframe and opposite to the outer surface of the end casting reinforcement seats 101. Two central underframe support members 5 located in the middle positions in the same row are respectively positioned below the central casting reinforcement seats 104 at the center position of the long side of the central underframe and opposite to the outer surface of the central casting reinforcement seats 104.

[0051] The central base support 5 includes a positioning plate 51, a support plate 52, four vertically extending columns 53, a base plate 54, a horizontal pad (not shown), and a vertical pad (not shown).

[0052] The central base frame support 5 provides a horizontal support surface F1 and a vertical support surface F2. The vertical support surface F2 is connected to the horizontal support surface F1 to form a right-angled dihedral angle, and the horizontal support surface F1 is located on the side of the vertical support surface F2 facing the opposite row of central base frame support 5.

[0053] Specifically, the positioning plate 51 is an L-shaped bent plate, providing a horizontal support surface F1 and a vertical support surface F2. Under the condition of meeting assembly accuracy, the distance between the lower surfaces of the middle casting reinforcement seat 104 and the end casting reinforcement seat 101 of the middle base frame 100 and the horizontal support surface F1 should be the expected vertical spacing G01, and the distance between the outer surfaces of the middle casting reinforcement seat 104 and the end casting reinforcement seat 101 of the middle base frame 100 and the vertical support surface F2 should be the expected lateral spacing G02.

[0054] In this embodiment, the expected vertical spacing G01 is 10mm and the expected horizontal spacing G02 is 20mm.

[0055] A support plate 52 is disposed below the positioning plate 51, and the support plate 52 is used to support the positioning plate 51. In this embodiment, the support plate 52 is a single-layer plate. The support plate 52 can also be a multi-layer plate stacked together, thereby adjusting the height of the positioning plate 51.

[0056] The column 53 is located below the positioning plate 51 and is used to support the support plate 52. The column 53 is a channel-shaped profile with a channel-shaped cross-section, and the two slots are arranged opposite each other.

[0057] The base plate 54 is located below the column 53 and is used to support the column 53.

[0058] Specifically, the base plate 54 can be fixed to a uniform base section (not shown). The base section provides a reference horizontal plane for the central underframe support 5 and supports the central underframe support 5. The column 53 is provided to adjust the height of the support plate 52 so that the height of the positioning plate 51 is maintained at the expected vertical distance G01 between the lower surfaces of the central casting reinforcement seat 104 and the end casting reinforcement seat 101 of the central underframe 100 of the railway concave-bottom flatcar body to be assembled.

[0059] The horizontal pad can be detachably placed on the horizontal support surface F1, and the vertical pad can be detachably placed on the vertical support surface F2. The horizontal and vertical pads are independent plates. The thickness of the horizontal pad is equal to the expected vertical spacing G01, and the thickness of the vertical pad is equal to the expected horizontal spacing G02.

[0060] All horizontal support surfaces F1 of the central base frame support members 5 are located in the same horizontal plane, and all horizontal pads are of equal thickness. The vertical support surfaces F2 of the same row of central base frame support members 5 are located in the same vertical plane, and all vertical pads are of equal thickness. The two vertical planes defined by the vertical support surfaces F2 of the two rows of central base frame support members 5 are parallel.

[0061] Under the condition of meeting the assembly accuracy, the bottom surfaces of the middle casting reinforcement seat 104 and the end casting reinforcement seat 101 of all the middle base frames 100 should be located on the same horizontal plane and at the expected height, and the outer surfaces of the middle casting reinforcement seat 104 and the end casting reinforcement seat 101 of the same row of middle base frames 100 should be located on the same vertical plane and at the expected position.

[0062] When assembling the railway concave-bottom flatcar body, first place a horizontal pad on the horizontal support surface F1. By observing the vertical gap between the upper surface of the horizontal pad and the long side of the central underframe, it is possible to help determine whether the central underframe is level and whether it is deformed. Then, hoist the central underframe 100, keeping it horizontal and without any positional deviation. Next, place a vertical pad on the vertical support surface F2 to eliminate the horizontal gaps between the central casting reinforcement seat 104 and the end casting reinforcement seat 101 and the positioning plate 51. After the railway concave-bottom flatcar body is assembled, remove the vertical pad. Finally, hoist and remove the railway concave-bottom flatcar body. Before placing the vertical pad, by measuring the horizontal gaps between the central casting reinforcement seat 104 and the end casting reinforcement seat 101 and the positioning plate 51, it is also possible to determine whether the deformation of the central underframe 100 exceeds the set requirements and whether the central underframe 100 is tilted.

[0063] refer to Figure 5Multiple threaded holes 1000 are provided on the positioning plate 51 and the support plate 52 in a corresponding manner. Screws (not shown) are screwed into the corresponding threaded holes 1000 on the positioning plate 51 and the support plate 52 to fix the positioning plate 51 and the support plate 52. The threaded holes 1000 on the positioning plate 51 are stepped holes. The diameter of the upper section of the stepped hole is larger than the diameter of the lower section of the stepped hole. The screw head is located in the upper section of the stepped hole and the screw head is lower than the top surface of the positioning plate 51.

[0064] The upper section of the stepped hole accommodates the screw cap, preventing the screw from interfering with the horizontal pad structure.

[0065] refer to Figure 6 The number of the two rows of middle base frame support members 5 is equal and they are aligned along the normal direction of the vertical support surface F2 (that is, the width direction of the middle base frame 100; note that the middle base frame 100 is placed in a position without deviation).

[0066] refer to Figure 6 In the same row of central base frame support members 5, some adjacent central base frame support members 5 are spaced apart, while others are in contact with each other. Specifically, because the central casting reinforcement seat 104 is relatively long, it requires a large support area. The two central base frame support members 5 opposite to the central casting reinforcement seat 104 are in contact with each other, and the gap between them is negligible. The end casting reinforcement seat 101 requires a smaller support area. There is only one central base frame support member 5 opposite to the end casting reinforcement seat 101. Since the end casting reinforcement seat 101 and the central casting reinforcement seat 104 are spaced apart, the corresponding central base frame support members 5 are also spaced apart.

[0067] In this embodiment, the positioning plate 51, support plate 52, base plate 54, horizontal pad, and vertical pad are all steel plates. The column 53 is a channel steel.

[0068] Example 2

[0069] The only difference between Example 2 and Example 1 is that column 53 is a rectangular steel pipe.

[0070] Example 3

[0071] Example 3 provides a railway concave-bottom flatcar body assembly system, including the central underframe inspection device of Example 1 or Example 2.

[0072] The railway concave-bottom flatcar assembly system may also include components that support, inspect, or limit the remaining parts of the railway concave-bottom flatcar body. Example 3 does not limit this and can be designed according to existing technology.

[0073] This utility model is not limited to the above-described embodiments. Any modifications, improvements, or substitutions that can be conceived by those skilled in the art without departing from the essential content of this utility model fall within the scope of this utility model.
