Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, specifically to a gooseneck trough structure for a container and the container itself. Background Technology

[0002] Some semi-trailers are equipped with gooseneck beams. To accommodate the gooseneck beams of the semi-trailers, gooseneck channels are installed on the container's underframe. After the four corner pieces of the container's underframe are interlocked with the semi-trailer using twist locks, the gooseneck beams of the semi-trailers are embedded in the gooseneck channels of the container's underframe. In existing container underframes, the gooseneck channel is formed by a gooseneck top plate, two gooseneck side beams, and multiple gooseneck top beams. The two gooseneck side beams are located on both sides below the gooseneck top plate. In some container underframes using wooden floors, the two gooseneck side beams are formed by bending downwards from both sides of the gooseneck top plate. The gooseneck top beams are welded to the lower surface of the gooseneck top plate and extend along the width of the underframe. Multiple gooseneck top beams are arranged along the length of the underframe, forming the gooseneck channel together with the bottom surfaces of the top beams and the two gooseneck side beams. In some container underframes using steel floors, the two gooseneck side beams are welded to the lower surface of the steel floor, and the steel floor is located on the two gooseneck... The section between the side beams forms the gooseneck top plate. Multiple gooseneck top beams are welded to the lower surface of the steel floor and located between two gooseneck side beams. Although the existing gooseneck channel structure can adapt the container's underframe to the gooseneck beams of the semi-trailer, the strength at the gooseneck channel location is relatively low because the container's bottom crossbeams cannot be arranged at the location of the underframe gooseneck channel. When the gooseneck top plate is subjected to dynamic downforce, it is prone to deformation. For example, when loading and unloading cargo in the container, the downforce exerted by the wheels on the gooseneck top plate when forklifts or other cargo handling vehicles move over the gooseneck top plate can easily cause bending deformation of the gooseneck top plate. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to propose a gooseneck groove structure for containers, which can improve the strength of the gooseneck groove structure on the container underframe and prevent deformation of the gooseneck top plate.

[0004] The second objective of this utility model is to provide a container.

[0005] To achieve the first objective mentioned above, this utility model adopts the following technical solution: The gooseneck trough structure of the container is located on the container's underframe and includes a gooseneck top plate, two gooseneck side beams, and multiple gooseneck top beams. The two gooseneck side beams extend along the length of the underframe. The gooseneck top beams are welded and fixed to the lower surface of the gooseneck top plate and extend along the length of the underframe. The multiple gooseneck top beams are arranged along the width of the underframe. The bottom surface of the gooseneck top beams and the inner surfaces of the two gooseneck side beams together form the gooseneck trough. The width of the gooseneck top beam is W1, and the interval between adjacent gooseneck top beams is W2, where W1 / W2 is 0.9~1.2.

[0006] W1 / W2 is 1, where W1 is 90~110mm.

[0007] The cross-section of the gooseneck top beam is U-shaped or square so that the lower surface of the bottom wall of the gooseneck top beam forms a plane, and the top two sides of the gooseneck top beam are welded and fixed to the lower surface of the gooseneck top plate.

[0008] Multiple support beams are welded and fixed to the lower surface of the gooseneck top plate. The two ends of the support beams are welded and fixed to the two gooseneck side beams respectively. The multiple support beams are intersected with the multiple gooseneck top beams so that the height difference between the bottom surface of the support beams and the bottom surface of the gooseneck top beams is within the range of 0~2mm.

[0009] The gooseneck top beam is divided into multiple gooseneck top beam units arranged along the length of the base frame by multiple supporting crossbeams. The ends of the gooseneck top beam units are welded and fixed to the supporting crossbeams.

[0010] The supporting beams are divided into multiple supporting beam units arranged along the width of the base frame by multiple gooseneck top beams, and the ends of the supporting beam units are welded and fixed to the gooseneck top beams.

[0011] The gooseneck side beam is formed by bending the side of the gooseneck top plate downwards. Supports are welded to the outer surface of the gooseneck side beam to support the floor of the base frame.

[0012] The base frame includes a steel floor laid on top of the base frame, and the tops of the two gooseneck side beams are welded and fixed to the lower surface of the steel floor. The portion of the steel floor between the two gooseneck side beams forms the gooseneck top plate.

[0013] The height of the gooseneck top beam is h, where h / W1 is 0.15~0.4.

[0014] To achieve the second objective mentioned above, this utility model adopts the following technical solution: Containers, including the gooseneck trough structure of the aforementioned containers.

[0015] The beneficial effects of this utility model are as follows: This invention features multiple gooseneck beams extending along the length of the container chassis on the lower surface of the gooseneck top plate, increasing the strength of the gooseneck groove structure. The spacing and width of adjacent gooseneck beams are rationally set. When a forklift operates above the chassis, at least one gooseneck beam is supported under the forklift wheel. The downward pressure exerted by the wheel on the gooseneck top plate can be transmitted to the gooseneck beam under the forklift wheel. The longitudinally arranged gooseneck beams disperse the downward pressure of the forklift wheel, thereby preventing the gooseneck top plate from bending downwards, especially preventing upward bending deformation at the front and rear positions of the gooseneck top plate in contact with the wheel.

Detailed Implementation

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1 , 2As shown, this is the gooseneck trough structure of a container according to Embodiment 1 of this utility model. It is located on the bottom frame of the container. The bottom frame is made of wooden floor 100. The gooseneck trough structure includes a gooseneck top plate 10, two gooseneck side beams 20, and multiple gooseneck top beams 30. The two gooseneck side beams 20 extend along the length of the bottom frame and are located on both sides below the gooseneck top plate 10. The two gooseneck side beams 20 are staggered by a certain distance along the width of the bottom frame. The multiple gooseneck top beams 30 are welded and fixed to the lower surface of the gooseneck top plate 10. The gooseneck top beams 30 extend along the length of the bottom frame and are arranged between the two gooseneck side beams 20 along the width of the bottom frame. The bottom surface of the gooseneck top beams 30 and the inner surface of the two gooseneck side beams 20 together form the gooseneck trough. The width of the gooseneck top beam 30 is W1, and the distance between adjacent gooseneck top beams 30 is W2, where W1 / W2 is 0.9~1.2. Preferably, W1 / W2 is 1, that is, W1 and W2 are equal. For example, the width W1 of the gooseneck top beam 30 is 100mm, and the distance W2 between adjacent gooseneck top beams 30 is also 100mm. W2 can also be slightly smaller than W1, or it can be set to be slightly larger than W1. The preferred value range of W1 is 90mm~110mm. The cross-section of the gooseneck top beam 30 is U-shaped, and it is formed by bending steel plate. The top two sides of the U-shape of the gooseneck top beam 30 are welded to the lower surface of the gooseneck top plate 10 by a weld. The lower surface of the bottom wall of the gooseneck top beam 30 forms a plane, thus making the top of the gooseneck groove a plane or approximately a plane. The gooseneck top beam 30 can also be made of square tube, making the cross-section of the gooseneck top beam 30 square. In other embodiments, the cross-section of the gooseneck top beam 30 can be set as an inverted trapezoid, semicircle, etc., as needed.

[0018] See Figure 3 As shown, when loading and unloading goods, the forklift wheels of the container underframe with the above-mentioned gooseneck groove structure are positioned above the gooseneck top plate 10. Since multiple gooseneck top beams 30 extending along the length of the container underframe are set on the lower surface of the gooseneck top plate 10, the strength of the gooseneck groove structure is increased. The spacing and width of adjacent gooseneck top beams 30 are reasonably set. When the forklift is working above the underframe, at least one gooseneck top beam 30 is supported under the forklift wheel. The downward pressure exerted by the wheel on the gooseneck top plate 10 can be transmitted to the gooseneck top beam 30 under the forklift wheel. The downward pressure of the forklift wheel is dispersed by the longitudinally arranged gooseneck top beam 30, thereby preventing the gooseneck top plate 10 from bending downwards, especially preventing the front and rear positions of the gooseneck top plate 10 in contact with the wheel from bending upwards.

[0019] In order to allow the gooseneck top beam 30 to have a slightly larger dimension in the width direction of the base frame while avoiding excessive weight of the base frame, the gooseneck top beam 30 is designed with a smaller height and a larger width. The height of the gooseneck top beam 30 is h, and h1 / W1 is preferably 0.15~0.4, with h / W1 being 0.25. For example, when the width W1 of the gooseneck top beam 30 is set to 100mm, the height h of the gooseneck top beam 30 is 25mm.

[0020] In one embodiment of this utility model, a plurality of supporting crossbeams 40 are welded to the lower surface of the gooseneck top plate 10. The two ends of the supporting crossbeams 40 are respectively welded and fixed to the two gooseneck side beams 20. The plurality of supporting crossbeams 40 and the plurality of gooseneck top beams 30 are intersected and arranged to form a frame structure on the lower surface of the gooseneck top plate 10. The bottom surface of the supporting crossbeams 40 is flush with the bottom surface of the gooseneck top beams 30. Considering some processing errors and assembly errors caused by welding deformation during the welding process, there is a height difference of less than 2mm between the bottom surface of the supporting crossbeams 40 and the bottom surface of the gooseneck top beams 30. That is to say, the bottom surface of the supporting crossbeams 40 is flush with or basically flush with the bottom surface of the gooseneck top beams 30.

[0021] The gooseneck top beam 30 is divided into multiple gooseneck top beam units 31 arranged along the length of the base frame by multiple supporting crossbeams 40. The ends of the gooseneck top beam units 31 are welded and fixed to the supporting crossbeams 40. The gooseneck top beam 30 is broken into multiple gooseneck top beam units 31 so that the gooseneck top beam 30 and the supporting crossbeams 40 can intersect and be welded to the lower surface of the gooseneck top plate 10. In other embodiments, the gooseneck top beam 30 can be set as an integral structure, and the supporting crossbeams 40 are divided into multiple supporting crossbeam units arranged along the width of the base frame by multiple gooseneck top beams 30. The ends of the supporting crossbeam units are welded and fixed to the gooseneck top beam 30.

[0022] In one embodiment, the gooseneck side beam 20 is formed by bending the side of the gooseneck top plate 10 downwards. A support member 201 is welded to the outer surface of the gooseneck side beam 20. The support member 201 is used to support the floor 100 of the base frame. The floor 100 is a wooden floor. By setting the support member 201 at an appropriate height and then overlapping the floor 100 onto the support member 201, the upper surface of the floor 100 is flush with the upper surface of the gooseneck top plate 10, thereby making the top surface of the base frame a flat surface.

[0023] like Figure 4 As shown, this is the gooseneck trough structure of a container according to Embodiment 2 of this utility model. The container's base frame includes a steel floor 600 laid on top of the base frame. The tops of two gooseneck side beams 50 are welded and fixed to the lower surface of the steel floor 600. The two gooseneck side beams 50 are staggered by a certain distance. The portion of the steel floor 600 between the two gooseneck side beams 50 forms a gooseneck top plate 60. In Embodiment 2, the gooseneck top beam 30 is the same as in Embodiment 1.

[0024] The container of this utility model includes the gooseneck groove structure of the aforementioned container. Other structures of the container are the same as those in the prior art and will not be described in detail here.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
