Description

Technical Field

[0001] The present application belongs to the technical field of vehicle axles, and in particular relates to an open top box. Background Art

[0002] An open top container is also called an open top container or open top box. This type of open top box does not have a rigid roof, but has a canopy made of canvas, plastic sheeting or plastic-coated cloth supported by a foldable top beam. The top is covered with waterproof cloth during shipment. Its watertight requirements are the same as those of a dry cargo box, and cargo can be loaded and unloaded from the top of the box by a crane.

[0003] In the related art, the open top box is a standard container type. For some goods, especially light and bulky goods, when this type of open top box is used for loading, it is often found that there is still a shortage of tons after being fully loaded, and the marked load cannot be reached, which greatly restricts the economic efficiency of transportation and puts the cargo owner under the pressure of transportation costs. At the same time, the open top box generally needs to be unloaded on a car. When unloading, the box door at one end is opened first, and the end of the open top box is slowly lifted up by the lifting cylinder on the car near the driver's cab of the other end, so that the open top box is at a certain angle to the ground so that the goods can flow out automatically. During the unloading process, it is often necessary to increase the flow of goods with the help of manual or other mechanical equipment. After unloading, some goods are also easily accumulated in the open top box, which needs to be further cleaned. This results in low unloading efficiency and high unloading cost of the open top box.

[0004] In summary, the open top containers of related technologies have problems of tonnage loss and low unloading efficiency, which in turn leads to high application costs of the open top containers. Summary of the invention

[0005] The present application aims to solve the technical problem of open top container tonnage loss at least to a certain extent. To this end, the present application provides an open top container that can increase the structural volume, increase the cargo loading capacity, improve the economic efficiency of cargo transportation, and significantly reduce the transportation cost of some cargo, especially light and bulky cargo.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Please refer to Figure 1In an embodiment of the present application, an open top container is provided, which includes a base frame 100, two end walls 300 and two side walls 200, which can be welded to each other. To ensure the structural strength, the following components are connected by welding, so that a container with an open top is formed by welding, that is, an open top container. Corner pieces are arranged at the upper and lower corners of the open top container, and the four corner pieces of the base frame 100 are designed with rounded corners. The open top container meets the requirements of stacking and intermodal transport. The bottom frame 100 has two opposite ends and two opposite sides. The two opposite ends are located in a first direction, and the two opposite sides are located in a second direction. The first direction is perpendicular to the second direction. The first direction is the direction in which the two end walls 300 are connected, and the second direction is the direction in which the two side walls 200 are connected. The two end walls 300 are respectively connected to the opposite ends of the bottom frame 100, that is, the bottom edges of the two end walls 300 are respectively connected to the end edges of the bottom frame 100 to form the foundation of the open top box. The two side walls 200 are further connected to the opposite sides of the bottom frame 100. The bottom edge is connected to the side edge of the bottom frame 100, and the side edges of the side wall 200 in the first direction are respectively connected to the side edges of the end wall 300 in the second direction, that is, the side edges of the side wall 200 are connected to the side edges of the end wall 300, so as to form an open top container; wherein, the side wall 200 is protruded in the second direction away from the bottom frame 100, and the side wall 200 is no longer a plate-like structure. The side wall 200 protrudes outward in the second direction to form a special shape, that is, the side wall 200 is arched outwardly toward both sides of the bottom frame 100, and the side wall 200 exceeds the two side edges of the traditional container, thereby increasing the volume.

[0035] The existing open top container has a rectangular structure, with side panels that do not extend beyond the edge of the chassis, and a door at one end. The China State Railway Group Co., Ltd. corporate standard Q / CR 625-2022 "20-foot 35t open top container" stipulates that the volume of a 20-foot open top container operated by my country's railways should be greater than or equal to 39.4m 3. At present, the existing open top containers in my country have small volume, which causes loss of tons and high costs. The existing traditional containers are designed as square boxes. This is because: First, the square design makes the container have uniform size and specifications, which helps to achieve standardized transportation worldwide. Standardized containers can be easily loaded onto various means of transportation, such as ships, trains and trucks, without additional adaptation or adjustment. This interoperability greatly improves logistics efficiency and reduces transportation costs; second, the design of square containers maximizes the use of internal space. Compared with other shapes, squares have a larger internal volume under a given volume, which means that more goods can be loaded, so that the goods can be stacked more tightly in the container, reducing space waste; third, the standardized size of square containers makes them easy to operate by various handling equipment, such as forklifts, cranes, etc., and the four corners of the container are right angles, which is convenient for fixing with locks, lashings and other tools to prevent shaking or tipping during transportation. Therefore, the current general design is to design the container as a rectangular box. Ordinary technicians have no motivation to change the overall design appearance, and are limited by specification requirements and have no inspiration to design it into other shapes.

[0036] Taking into account that the railway limit width in my country exceeds 3 meters and the width of the railway flat car chassis is far greater than the width of my country's open top container (2550mm wide), it is possible to improve the structure on both sides of the original traditional open top container. Therefore, the present application is improved on the basis of the original traditional side wall 200 in a plate-like structure, and a container with an open top is formed by connecting the side wall 200, the bottom frame 100 and the end wall 300. The side wall 200 protrudes in the second direction away from the bottom frame 100, that is, the side wall 200 protrudes outward, making full use of the railway limit. In this way, the volume of the original square box is increased, and the volume on both sides of the traditional container is increased, thereby providing a larger loading space and reducing the loss of tons. More goods can be loaded per unit container, thereby reducing the cost of goods per unit volume. Therefore, the present application can increase the structural volume, increase the cargo loading capacity, improve the transportation economy of goods, and can significantly reduce the transportation cost of some goods, especially light and bulky goods.

[0037] Please refer to Figure 2In some embodiments, both side edges of the base frame 100 are expanded outward to form curved edges, which can be set to form a convex polygon or a convex arc edge. In this way, the base frame 100 has a variable cross-section structure in both the first direction and the second direction. In the first direction, the size of the base frame 100 decreases from the side edge to the end edge, and in the second direction, the size of the base frame 100 decreases from the end edge to the side edge, thus forming a variable cross-section structure, so that the bottom edge of the side wall 200 protrudes outward from the top edge of the side wall 200 in the second direction, thereby increasing the supporting area on both sides of the base frame 100. In some embodiments, the side wall 200 protrudes from the surface where the top and bottom edges of the side wall 200 are located in a direction away from the base frame 100. The surface from the top edge to the bottom edge of the side wall 200 is a plane or a curved surface. Taking the plane from the top edge to the bottom edge as an example for explanation, the side wall 200 is arranged to protrude outward, so that the side wall 200 protrudes from the plane, similar to the side wall 200 expanding and protruding outward from the plane. Through the above arrangement, the load-bearing bottom surface of the open top box and the loading space on both sides of the open top box are increased on both sides of the base frame 100 in the second direction.

[0038] Please refer to Figure 3 In some embodiments, the side wall 200 includes a connected side wall 200 plate and an end side plate 220, the end side plate 220 is connected to the end wall 300 and the bottom frame 100, and is set as a curved surface, that is, the edge of one side of the end side plate 220 is connected to the side wall 200 plate, the edge of the other side of the end side plate 220 is connected to the side of the end wall 300, and the edge of the third side of the end side plate 220 is connected to the side of the bottom frame 100, so that the end side plate 220 is bent from the side of the end wall 300 to the side of the bottom frame 100; the side wall 200 plate is connected to the bottom frame 100, and is set as a curved surface from the top edge of the side wall 200 to the bottom frame 100, the top edge of the side wall 200 plate serves as one side of the opening of the open top box, the bottom edge of the side wall 200 plate is the edge connected to the bottom frame 100, and the side wall 200 plate is bent from the top edge to the bottom edge. In this way, the end side panels 220 and the side wall 200 panels both form outwardly convex curved surfaces, wherein the end side panels 220 and the side wall 200 panels can be set to plate-like structures that are bent at least once, such as the end side panels 220 are bent once and the side wall 200 panels are bent twice, both forming outwardly convex curved surfaces, and the edges of the two ends of the side wall 200 panels in the first direction are connected to the end side panels 220. The curved surface formed by the above-mentioned bending setting can also avoid the operating space of the corner fittings, which is convenient for the locking operation of the corner fittings and personnel observation during transportation.

[0039] Please refer to Figure 4In an optional embodiment, the side wall 200 further includes a top side beam 230, an upper frame 240, a vertical frame 250, and a lower frame 260. The top side beam 230 is made of square steel, and the upper frame 240, the vertical frame 250, and the lower frame 260 are respectively made of bent steel plates, the bent steel plate has two side surfaces, wherein one side surface of the upper frame 240 is connected to the bottom of the top side beam 230, and the other side surface is connected to the inner side of the top edge of the side wall 200 plate, the upper frame 240 is bent at an obtuse angle, one side surface of the vertical frame 250 is connected to the side of the end wall 300, and the other side surface is connected to the inner side of the edge of the end side plate 220, the vertical frame 250 can be set as a right-angle bent steel plate, one side surface of the lower frame 260 is connected to the inner side of the bottom edge of the side wall 200 plate, and the other side surface is connected to the side of the bottom plate frame 100, and the lower frame 260 can also be set as a three-section bent structure, thus forming the entire side wall 200 structure. In an optional embodiment, the side wall 200 also includes a reinforcing rib 270. The reinforcing rib 270 can be provided in multiple and spaced apart configurations. The multiple reinforcing ribs 270 are spaced apart along the first direction of the side wall 200 plate. The reinforcing rib 270 extends from the top edge to the bottom edge of the side wall 200 plate, thereby improving the structural strength of the side wall 200 plate.

[0040] When the existing open top box is transported to the owner's factory by car, the existing open top box structure opens the end door to unload the goods from one side. When used for transshipment, it can be forked, but it is limited to lifting the open top box. The unloading operation of the open top box often requires manual assistance to ensure that the goods can flow out of the door smoothly to avoid accumulation of goods in the box. In addition, the car needs to unload while moving, which leads to a large cargo stacking area, requiring the owner to have a sufficiently large cargo yard. Therefore, the existing unloading method has the disadvantages of low efficiency, long unloading time, high labor cost, and large storage area. In addition, the present application improves the bottom plate frame 100:

[0041] Please refer to Figure 5 In some embodiments, the bottom frame 100 includes a frame body 110 and at least one slot beam 120. The two ends of the frame body 110 are respectively connected to the end wall 300 and the two sides are respectively connected to the side wall 200. The slot beam 120 is arranged along the second direction, that is, the slot beam 120 is arranged along the two sides of the frame body 110. At least one end of the slot beam 120 is provided with a slot. The slot beam 120 has an open structure at both ends and a closed structure on each side. For example, the slot beam 120 is set as a rectangular steel with open ends and hollow communication. The slot is the internal through groove of the rectangular steel. The slot is used for inserting tools to flip the open top box. In this way, the goods in the open top box can be efficiently unloaded through the arrangement of the slot beam 120, reducing the labor cost of the unloading operation; at the same time, it can be unloaded anywhere, which is convenient and flexible. In some embodiments, the bottom frame 100 also includes a bottom plate 118. The bottom plate 118 is plate-shaped and is a steel plate. The shape of the bottom plate 118 matches the shape of the frame body 110. The bottom plate 118 is welded to the top of the frame body 110 and serves as a placement plane for the goods.

[0042] In some embodiments, the frame body 110 includes at least one bottom side beam 111 arranged along the first direction. The bottom side beam 111 is made of square steel, and its two ends are connected with angle pieces. The bottom side beam 111 is connected with the slot beam 120 in an inlaid manner. Angle pieces are set at both ends of the bottom side beam 111. The bottom side beam 111 serves as the two side references of the bottom plate frame 100. Both side edges of the bottom plate frame 100 are located on the outside of the bottom side beam 111. The inlay of the bottom side beam 111 and the slot beam 120 is achieved by slot clamping. For example, the bottom side beam 111 is provided with a notch from top to bottom to ensure that the bottom of the bottom side beam 111 is not disconnected. The slot beam 120 is vertically inserted into the slot to match, and the two ends of the slot beam 120 exceed the bottom side beam 111 and extend in both directions to achieve the interlocking of the slot beam 120 and the bottom side beam 111; the thickness of the slot beam 120 in the vertical direction is equivalent to that of the bottom side beam 111, and the top height of the slot beam 120 after being embedded in the bottom side beam 111 is higher than the bottom side beam 111, which can avoid the bottom surface of the slot beam 120 and the bottom side beam 111 being in the same plane, reduce the disconnection of the bottom side beam 111, and enhance the bearing strength, so that it has sufficient strength to use the slot to flip the open top box as a whole through the teeth.

[0043] Please refer to Figure 6 In some embodiments, the frame 110 further includes a first reinforcement seat 112, which is disposed at the inner corner formed by the connection between the bottom side beam 111 and the slot beam 120, and is connected to the bottom side beam 111 and the slot beam 120 respectively. The first reinforcement seat 112 can be configured as a triangle, wherein a right angle side of the first reinforcement seat 112 of the triangle is connected to the bottom side beam 111, and another right angle side is connected to the slot beam 120, so that the connection structure strength between the bottom side beam 111 and the slot beam 120 can be improved. The first reinforcement seat 112 can be set on both sides of the bottom side beam 111, so that supports are formed at the four inner corners. The first reinforcement seat 112 can be made of C-shaped structural steel, wherein the top of the first reinforcement seat 112 is connected to the bottom plate 118, and the vertical side of the first reinforcement seat 112 is connected to the bottom side beam 111 and the slot beam 120. The length of the first reinforcement seat 112 in the second direction is greater than the length in the first direction, thereby ensuring the structural strength of the slot beam 120 outside the bottom side beam 111.

[0044] In some embodiments, the frame body 110 also includes a second reinforcement seat 113, which is arranged at the bottom of the slot beam 120 at the connection between the bottom side beam 111 and the slot beam 120. The second reinforcement seat 113 enhances the bottom strength of the bottom of the bottom plate frame 100 during flipping and unloading at the bottom of the slot beam 120; for example, a second reinforcement seat 113 with a length of 100 mm is provided at the connection between the end of the slot beam 120 and the bottom side beam 111. The second reinforcement seat 113 adopts a plate-like structure with a certain thickness, which can support the entire bottom plate frame 100 to ensure the structural strength of the connection between the bottom side beam 111 and the slot beam 120, and meet the strength requirements for flipping and unloading through the slot beam 120.

[0045] In some embodiments, at least two bottom side beams 111 are provided, and the frame 110 further includes a plurality of first cross beams 114, which are arranged at intervals between adjacent bottom side beams 111. For example, two bottom side beams 111 are provided and arranged at intervals, and the bottom side beams 111 are connected by a plurality of first cross beams 114, and the first cross beams 114 are made of C-shaped steel, and the top of the first cross beam 114 is welded and fixed to the bottom plate 118. The first cross beam 114 has a vertical section to enhance the structural strength of the entire frame 110, and the two ends of the first cross beam 114 are welded and fixed to the side surfaces of the two bottom side beams 111, and the first cross beam 114 is perpendicular to the bottom side beams 111. In some embodiments, the bottom side beams 111, the side beams 116, the first reinforcement seat 112, and the second reinforcement seat 113 are all arranged in the same plane, and the top of each component is welded to the bottom of the bottom plate 118, and the other components of the frame 110 are also arranged in the same plane, so that sufficient strength of the bottom plate frame 100 can be ensured.

[0046] In some embodiments, the frame 110 further includes a side beam 116, an end beam 117 and a plurality of second cross beams 115, the side beam 116 being the side of the above-mentioned bottom plate frame 100, the end beam 117 being the end of the above-mentioned bottom plate frame 100, and the plurality of second cross beams 115 being respectively connected to the side beam 116 and the bottom side beam 111, and the end beam 117 and the first cross beam 114; the side beam 116 being the side of the above-mentioned bottom plate frame 100, the side beam 116 being arranged on the outer side of the bottom side beam 111, the side beam 116 being arranged in a bent manner, and the two ends of the side beam 116 being respectively connected to the two ends of the bottom side beam 111, the side beam 116 being arranged in a C-shaped structural steel, the top surface of which is welded and fixed to the bottom plate 118, and the vertical side surface of which is used to support the bottom plate 118, the side beam 116 being divided into three sections, the middle section being parallel to and spaced from the bottom side beam 111, the two end sections being connected to the two ends of the middle section to form a trapezoid, and the two The end section is bent from the middle section to the corner piece of the base frame 100 and connected to the corner piece. The side beams 116 are arranged on both sides of the bottom side beams 111 to increase the volume, make full use of the railway limit, and increase the cargo loading capacity; the end side beams 117 are located at both ends of the frame 110, arranged at intervals and in parallel, and the two ends of the end side beams 117 are respectively connected to the corner pieces of the base frame 100; on both sides of the frame 110, the bottom side beams 111 and the side beams 116 are connected by a second cross beam 115, and at both ends of the frame 110, the end side beams 117 and the first cross beam 114 are also connected by a second cross beam 115. The second cross beam 115 is a variable-section channel steel. The side beams 116 and the second cross beam 115 are arranged to further increase the bottom bearing area of ​​the base frame 100, and the second cross beam 115 can enhance the supporting strength of the base frame 100 to ensure uniform load transfer.

[0047] In order to meet the large volume demand, this application specially designs a large volume open top box according to the railway limit. The side wall 200 is a special-shaped structure, which can increase the volume to 51.4m 3 , which is 23% larger than the existing product volume. In order to achieve efficient and low-cost unloading operations, a special forklift with rotatable teeth is used to lift the box from the slot beam 120 of the bottom frame 100, and rotate the box 180° until the opening faces downward, unloading all the goods at one time without additional manual cleaning, which is convenient and fast; at the same time, corner pieces are set on the top and bottom of the box to meet the requirements of stacking and intermodal transportation, and the transportation method is flexible.
