[0043] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application can be practiced without one or more of these specific details. In other instances, well-known features have not been described in detail so as not to unnecessarily obscure the present application.
[0044] The preferred embodiments of the present application will be described hereinafter with reference to the drawings. It is noted that the terms "upper", "lower" and similar expressions used herein are for the purpose of illustration only and are not limiting.
[0045] In this document, the ordinal numbers such as "first" and "second" cited in the present application are merely identifiers and do not have any other meaning, such as a specific order, etc.
[0046] For a thorough understanding of the present application, a detailed description will be made in the following description. Obviously, the implementation of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.
[0047] The present application provides a kind of tray. Tray can be used for open wagon of railway. The end frame 120 of tray can abut the inner wall surface of the end wall 161 of open wagon. The inner wall surface of end wall 161 can support end frame 120. In this way, when tray carries roll-shaped goods (such as steel roll), the longitudinal load of roll-shaped goods to tray in the direction parallel to the length direction of carriage 160 of open wagon can be overcome.
[0048] It should be noted that the open wagon includes carriage 160. The carriage 160 is a substantially cuboid structure. The top end of the carriage 160 has a top opening. The length direction end of the carriage 160 is the end wall 161 of the carriage 160. The width direction side of the carriage 160 is the side wall of the carriage 160.
[0049] Please refer to Figures 1 to 6 , tray includes body 110. Body 110 includes body frame 119. Body frame 119 is formed by profile welding. Body frame 119 is a rectangular frame structure. When body frame 119 is arranged in open wagon, the length direction and width direction of body frame 119 are parallel to the horizontal direction. The length direction of body frame 119 is parallel to the length direction of carriage 160. The width direction of body frame 119 is parallel to the width direction of carriage 160.
[0050] Further, as shown in Figures 1 to 4 , body frame 119 includes body end beam 111 and body side beam 112. The length direction of body end beam 111 is the width direction of body frame 119. The length direction of body side beam 112 is the length direction of body frame 119. The ends of two body end beams 111 and two body side beams 112 are connected to form a rectangular frame structure.
[0051] Body frame 119 also includes body cross beam 113 and body longitudinal beam 114. The length direction of body cross beam 113 is parallel to the length direction of body end beam 111. Body cross beam 113 is located between two body end beams 111. The end of body cross beam 113 is connected to body side beam 112. The length direction of body longitudinal beam 114 is parallel to the length direction of body side beam 112. Body longitudinal beam 114 is located between two body side beams 112. The end of body longitudinal beam 114 is connected to body end beam 111. Body cross beam 113 is connected to body longitudinal beam 114. In this way, the strength of body frame 119 is large.
[0052] like Figures 1 to 4 As shown, the pallet further includes an end frame 120. The end frame 120 is formed by welding profiles. The end frame 120 is a rectangular frame structure.
[0053] Furthermore, the end frame 120 includes a frame end beam 121 and a frame side beam 122. The length direction of the frame end beam 121 corresponds to the width direction of the end frame 120. The length direction of the frame side beam 122 corresponds to the length direction of the end frame 120. The ends of the two frame end beams 121 and the two frame side beams 122 are connected to form a rectangular frame structure.
[0054] The end frame 120 further includes a frame cross member 123. The length direction of the frame cross member 123 is parallel to the length direction of the frame end members 121. The frame cross member 123 is located between the two frame end members 121. The ends of the frame cross member 123 are connected to the frame side members 122. Thus, the end frame 120 has a high strength.
[0055] One frame side member 122 of the end frame 120 serves as a hinge end 124 of the end frame 120. The hinge end 124 of the end frame 120 is rotatably connected to one of the body end members 111 located at one end of the body frame 119. At this point, the length direction of the end frame 120 is parallel to the width direction of the body frame 119. Thus, the end frame 120 is rotatable between a frame stacking position and an upright position.
[0056] like Figure 3 、 Figure 4 and Figure 6 As shown, when the end frame 120 is in the frame stacking position, the length direction and width direction of the end frame 120 are parallel to the horizontal direction. At this time, the end frame 120 extends in the horizontal direction. In this way, the end frame 120 can be stacked on the main frame 119 via the support legs 130 described later. Multiple pallets can be stacked together. Figure 6 As shown, when the end frame 120 is located in the frame stacking position, the height of the pallet is small, and a plurality of pallets can be stacked on one open truck for convenient transportation.
[0057] like Figure 1 、 Figure 2 and Figure 5 As shown, when the end frame 120 is in the upright position, its width is parallel to the vertical direction. Thus, the end frame 120 extends in the vertical direction. In other words, the end frame 120 rotates 90° between the frame stacking position and the upright position. In this case, the tray can be positioned at the end of the gondola car along the length of the car body 160, with the upright end frame 120 and one end of the main frame 119 resting against the inner wall surface of the gondola car's end wall 161.
[0058] Please refer to Figures 1 to 4 , the tray further comprises a leg 130. The leg 130 is a rod structure. A first end 131 of the leg 130 is rotatably connected to the end frame 120. In the case that the end frame 120 is in the upright position, a second end 132 of the leg 130 can be detachably connected to the body frame 119 to lock the end frame 120 in the upright position.
[0059] It can be understood that in an embodiment not shown, the first end of the leg is rotatably connected to the body frame. In the case that the end frame is in the upright position, the second end of the leg can be detachably connected to the end frame to lock the end frame in the upright position.
[0060] In the embodiment, in the case that the tray is arranged in the open wagon, when the body frame 119 carries the roll-shaped cargo, the end frame 120 can be rotated to the upright position, and the second end 132 of the leg 130 is connected to the body frame 119 or the end frame 120. In this way, during the transportation of the roll-shaped cargo in the open wagon, the longitudinal load generated by the roll-shaped cargo due to inertia and other factors can be transmitted to the end wall 161 of the open wagon through the end of the body frame 119 and the end frame 120, and then overcome by the end wall 161 of the open wagon; in addition, the end frame 120 in the upright position and one end of the body frame 119 abutting against the inner wall surface of the end wall 161 of the open wagon can increase the contact area of the tray and the end wall 161, thereby avoiding damage to the end wall 161 or the tray; the leg 130 locking the end frame 120 in the upright position can make the end frame 120 more stably maintain in the upright position, thereby more effectively overcoming the longitudinal load; in this way, the tray can be used in some open wagons with damaged inner side column inner reinforcement seats.
[0061] Optionally, as shown in Figure 1 and Figure 2 , the length direction of the leg 130 supporting the end frame 120 in the upright position is inclined to the vertical direction. Thus, the leg 130 locking the end frame 120 in the upright position, the end frame 120 and the body frame 119 form a triangular structure. Thus, the triangular structure is stable in force.
[0062] Optionally, as shown in Figures 1 to 4 , the leg 130 is rotated between the leg stacking position and the leg supporting position. As shown in Figure 1 and Figure 2 , in the case that the leg 130 is in the leg supporting position, the two ends of the leg 130 are connected to the end frame 120 and the body frame 119 respectively to support the end frame 120 in the upright position.
[0063] As shown in Figure 3 and Figure 4As shown, when the legs 130 are in the leg-overlapping position, the length direction of the legs 130 is parallel to the length direction of the main frame 119. The legs 130 overlap the main frame 119. At this time, the end frame 120 in the frame-overlapping position overlaps the legs 130. As a result, the force applied to the pallet is stable when stacked on the frame.
[0064] like Figure 3 and Figure 4 As shown, the first ends 131 of the legs 130 are rotatably connected to the end frames 120. When the legs 130 are in the stacked position, the first ends 131 are located on the side of the second ends 132 closer to the hinge ends 124. Thus, when stacking pallets, the legs 130 support the free ends of the end frames 120, reducing the possibility of bending and deformation of the end frames 120.
[0065] Alternatively, as Figures 1 to 4 As shown, a shock-absorbing pad 140 is provided on the side of the end frame 120 facing away from the main frame 119. The shock-absorbing pad 140 can be a rubber member. Thus, when the end frame 120 is in the upright position, it abuts against the end wall 161 of the gondola via the shock-absorbing pad 140, thereby reducing the impact of the end frame 120 on the end wall 161.
[0066] like Figure 1 and Figure 2 As shown, the tray further includes a locking shaft 150. The leg 130 has a first mounting hole. The main frame 119 is provided with a second mounting hole. The locking shaft 150 is detachably inserted through the first and second mounting holes. This facilitates the installation and removal of the second end 132 of the leg 130.
[0067] like Figures 1 to 4 As shown, the tray includes two legs 130. The two legs 130 are spaced apart in the width direction of the body frame 119. Thus, the end frame 120 in the upright position can be supported more stably.
[0068] Please continue to refer to Figures 1 to 4 The main body 110 further includes a loading section 115 located above and connected to the main body frame 119. The loading section 115 has a loading slope 118 that is inclined relative to the vertical direction. The loading section 115 includes a first loading section and a second loading section. The loading slope 118 of the first loading section and the loading slope 118 of the second loading section form a V-shaped structure for loading rolled goods. This facilitates loading rolled goods.
[0069] Furthermore, each loading section 115 includes a first loading arm 116 and a second loading arm 117. One end of the first loading arm 116 is connected to the main body end beam 111. One end of the second loading arm 117 is connected to the main body cross beam 113. The length of the first loading arm 116 and the length of the second loading arm 117 form an angle. The other end of the first loading arm 116 is connected to the other end of the second loading arm 117. The second loading arm 117 has a loading slope 118. Thus, the first loading arm 116, the second loading arm 117, and the main body frame 119 form a triangular structure, which increases the strength of the loading section 115.
[0070] like Figures 1 to 4 As shown, the main body 110 includes two first loading sections and two second loading sections. The two first loading sections correspond to the two second loading sections. The corresponding loading slopes 118 of the first loading section and the loading slopes 118 of the second loading section form a V-shaped structure. The two first loading sections and the two second loading sections are spaced apart along the width of the main body frame 119. This allows for more stable loading of rolled goods.
[0071] Alternatively, as Figures 1 to 4 As shown, a gap exists between the body longitudinal beam 114 and the body side beam 112 of the body frame 119. When the legs 130 are in the leg support position, the second ends 132 of the legs 130 extend into the gap between the body longitudinal beam 114 and the body side beam 112 (inside the body frame 119) and are detachably connected to the body frame 119. Consequently, the end frame 120 does not need to have a clearance space to accommodate the structure connecting the second ends 132 of the legs 130 to the body frame 119. This simplifies the structure of the end frame 120.
[0072] Alternatively, as Figure 1 and Figure 2 As shown, the upper end of the end frame 120 in the upright position is higher than the loading portion 115. Thus, the contact area between the end frame 120 and the end wall 161 of the open car can be further increased, thereby reducing the possibility of damage to the end wall 161 and the pallet.
[0073] like Figures 1 to 4 As shown, the end frame 120 includes two frame crossbeams 123. The two frame crossbeams 123 are spaced apart to form an escape opening 125. When the end frame 120 is in the frame stacking position, the loading portion 115 extends through the escape opening 125. This allows the length of the end frame 120 to be as large as possible, further increasing the contact area between the end frame 120 and the end wall 161 of the gondola, thereby reducing the possibility of damage to the end wall 161 and the pallet.
[0074] Optionally, the end frame 120 further includes a reinforcement beam 126. The reinforcement beam 126 is positioned between the frame cross beam 123 and the frame end beam 121. One end of the reinforcement beam 126 is fixedly connected to the frame cross beam 123. The other end of the reinforcement beam 126 is fixedly connected to the frame end beam 121. The length of the reinforcement beam 126 is parallel to the frame side beam 122. The first end 131 of the support leg 130 is rotatably connected to the reinforcement beam 126. As a result, the end frame 120 is highly robust.
[0075] The present invention also provides an open car. The open car includes a car body 160, an intermediate pallet 162, and the aforementioned pallet. The difference between the intermediate pallet 162 and the pallet is that the intermediate pallet 162 only includes a main body, and does not include legs and end frames. When the intermediate pallet 162 and the pallet are arranged in the car body 160, pallets are arranged at both end walls 161 of the car body 160. Along the length direction of the car body 160, the part of the car body 160 between the two pallets is provided with a plurality of intermediate pallets 162 connected end to end. The intermediate pallet abuts the main body frame 119 of the pallet. In this way, the longitudinal load of the rolled goods carried by the pallet and the intermediate pallet 162 can be transferred to the end of the car body 160 via the pallet.
[0076] In this embodiment, the carriage 160 includes the aforementioned pallet. When the pallet is set on an open car, when the main frame 119 carries rolled goods, the end frame 120 can be rotated to an upright position, so that the second end 132 of the leg 130 is connected to the main frame 119 or the end frame 120. In this way, during the process of transporting rolled goods on the open car, the longitudinal load generated by the rolled goods on the pallet due to factors such as inertia can be transmitted to the end wall 161 of the open car via the end of the main frame 119 and the end frame 120, and then The end wall 161 of the gondola overcomes the longitudinal load; in addition, the end frame 120 and one end of the main body frame 119 in the upright position abut against the inner wall surface of the end wall 161 of the gondola, which can increase the contact area between the pallet and the end wall 161 and avoid damage to the end wall 161 or the pallet; the support legs 130 lock the end frame 120 in the upright position, and the end frame 120 can be more stably maintained in the upright position, thereby more effectively overcoming the longitudinal load; in this way, the pallet can be used in some gondolas with damaged reinforcement seats in the internal side columns.
[0077] Alternatively, as Figure 6 As shown, when the carriage 160 returns to transport the pallets and the intermediate pallets 162, the stacked pallets are located at the ends of the carriage 160. The stacked intermediate pallets 162 are located between the two ends of the carriage 160.
