Description

Technical Field

[0001] This utility model belongs to the field of transportation loading equipment design technology, and in particular to the structural design of transportation loading box, which relates to a box end structure with a double platform for a transportation loading box. Background Technology

[0002] Large containers typically consist of a hollow cuboid structure comprised of a base frame, side walls, end walls, and a top cover. The internal space is used to load goods, equipment, or personnel. The end walls are primarily composed of straight-walled column structures made of sheet metal and profiles, forming enclosed spaces with the base frame, side walls, and top cover, and their function is relatively singular. In some special locations, it is required that the outer ends of the container can accommodate outdoor equipment while fully utilizing the internal space. Therefore, it is necessary to research novel end walls that can both provide external space and improve the utilization rate of the container's internal space. Summary of the Invention

[0003] This utility model discloses a container end structure with dual platforms. The purpose of this utility model is to provide a container end structure design with dual platforms that allows for diverse spatial partitioning and multiple uses in transport and loading containers.

[0004] This utility model is achieved through the following technical solution:

[0005] A box-shaped structure with dual platforms is disclosed. The box consists of an end wall, a base frame, side walls, and a top cover. The structure is characterized by a dual-platform structure at one end, comprising two levels of platforms of varying heights. The dual-platform structure is horizontally distributed throughout the box, including a first platform with a height less than or equal to half the height of the box, and a second platform perpendicularly connected to the first platform and mounted on the base frame floor. A rectangular cavity is formed below the first platform, and an end wall is fixedly installed above the outer edge of the first platform. A window is opened at the center of the end wall, and the top of the end wall is connected to the top cover of the box. The side walls are respectively connected and fixed to both sides of the box.

[0006] Furthermore, the dual-platform structure consists of a two-level frame of vertical folding structure, comprising the first to fourth flat plates, the first to second angular beams, the first to fourth hat-shaped beams, the first to third channel beams, the first to second rectangular beams, and the first to fourth channel steel. The first flat plate is fixed to form the outer panel of the box end wall, the second flat plate is fixed to form the first platform panel, the third flat plate is fixed to form the outer end wall panel below the first platform of the box, and the fourth flat plate is fixed to form the second platform panel.

[0007] The window opening at the center of the end wall plane is vertically arranged with the first plate, closely attached to the inner side of the first plate and perpendicular to the side of the first plate. From top to bottom, the second triangular beam, the first cap-shaped beam, the third cap-shaped beam and the first rectangular beam with larger cross-sectional dimensions are fixed in sequence. The bottom edge of the first plate overlaps the first side of the first rectangular beam, closely attached to the inner side of the first plate and parallel to the side of the first plate.

[0008] Furthermore, the first trough-shaped beam, the fourth cap-shaped beam, the second cap-shaped beam, and the first angular beam are symmetrically fixed on both sides of the first flat plate, and intersect perpendicularly with the second angular beam, the first cap-shaped beam, the third cap-shaped beam, and the first rectangular beam, respectively, to form a grid-shaped plate-beam structure.

[0009] Furthermore, the edge of the third cap-shaped beam is flush with the long side of the window opening, and the edge of the second cap-shaped beam is flush with the short side of the window opening; the top of the second cap-shaped beam is attached to the second angled beam, and the bottom of the second cap-shaped beam is attached to the first top surface of the first rectangular beam.

[0010] Further, a second flat plate with small notches on both sides is horizontally fixed to the top surface of the first rectangular beam. Several parallel first channel steels are arranged on the second side of the first rectangular beam and the bottom of the second flat plate. The second end face of the first channel steel is attached to the second side of the first rectangular beam, and the third end face of the first channel steel is attached to the fourth side of the second rectangular beam. The top surface of the second rectangular beam is attached to the bottom surface of the second flat plate. The second rectangular beam is longer than the first rectangular beam, forming a second platform that is perpendicular to the first flat plate and is sturdy. A rectangular third flat plate, several second channel beams, and two third channel beams are vertically fixed to the bottom surface of the second rectangular beam in sequence to support the second platform. The height of the third flat plate is equal to the length of the second channel beams and the length of the third channel beams. The openings of the two third channel beams face the fourth end face of the second rectangular beam and are flush with the fourth end face of the second rectangular beam to increase the connection strength with the side wall of the matching box.

[0011] Furthermore, several second channel beams are evenly distributed between two third channel beams. The openings of the second channel beams face the third plate and fit against the third plate to form a closed structure, increasing the rigidity of the third plate. The height of the cross-section of the second channel beam is equal to the width of the cross-section of the third channel beam, ensuring that the fifth side of the second channel beam and the seventh side of the third channel beam can fit against the side of the second channel steel. The first platform, composed of the second channel steel, the third channel steel, and the fourth plate, is horizontally fixed. The first platform is lower than the second platform. The fourth plate is located at the top of the first platform. Several fourth channel steels are vertically fixed at the bottom of the first platform, providing multi-point and balanced support for the first platform. The bottom edge of the third plate, the bottom surface of the second channel beam, the bottom surface of the third channel beam, and the bottom surface of the fourth channel steel are flush, facilitating positioning and assembly on the matching box frame.

[0012] The first and third flat plates further separate the longitudinal space of the supporting box, and the horizontally arranged second platform separates the vertical space of the box, so that the lower part of the end wall, the supporting base frame, and the side wall form a rectangular cavity with an outward opening.

[0013] Seats are then fixed to the second platform.

[0014] This utility model features a box-shaped end structure with dual platforms. The end structure employs a zigzag wall to separate the longitudinal and vertical spaces of the box, accommodating different loading requirements for goods inside and outside the box. The first platform is narrower and lower, facilitating the loading of small goods and serving as a passageway for personnel to access the second platform. The second platform is wider and higher, facilitating the loading of larger goods and effectively utilizing the upper space of the rectangular cavity. The beams are primarily located on the inner side of the end wall, while the outer side of the end wall is flat and aesthetically pleasing. Attached Figure Description

[0027] The present invention will be further described below with reference to specific embodiments. These specific embodiments are further explanations of the principle of the present invention and are not intended to limit the present invention in any way. Any technology that is the same as or similar to the present invention does not exceed the protection scope of the present invention.

[0028] Refer to the attached diagram.

[0029] This embodiment describes a box-shaped structure with dual platforms. The box consists of an end wall, a base frame, side walls, and a top cover. One end of the box has a dual-platform structure consisting of two levels of high and low platforms. The dual-platform structure is horizontally distributed throughout the box and includes: a first platform with a height less than or equal to half the height of the box, and a second platform set on the base frame floor and connected at right angles to the first platform. A rectangular cavity is formed below the first platform, and an end wall is fixedly installed on the outer edge above the first platform. A window is opened at the center of the plane of the end wall, and the top is connected to the top cover of the box. The two side walls are respectively connected and fixed to both sides of the box.

[0030] The double-platform structure includes first to fourth flat plates, first to second angular beams, first to fourth cap-shaped beams, first to third channel beams, first to second rectangular beams, and first to fourth channel steel. The first flat plate, with rectangular window openings, is arranged vertically, closely attached to the inner side of the first flat plate and perpendicular to its side. From top to bottom, it is sequentially fixed to the second angular beam, first cap-shaped beam, third cap-shaped beam, and first rectangular beam with larger cross-sectional dimensions. The bottom edge of the first flat plate overlaps the first side surface of the first rectangular beam, closely attached to the inner side of the first flat plate and parallel to its side. The centerline extends to the side of the first flat plate. Symmetrically fixed to the shorter first channel beam, fourth cap-shaped beam, second cap-shaped beam, and the smaller first angular beam, these beams intersect perpendicularly with the second angular beam, first cap-shaped beam, third cap-shaped beam, and first rectangular beam, respectively, forming a grid-like plate-beam structure. The third cap-shaped beam has its edge flush with the long side of the window opening, while the second cap-shaped beam has its edge flush with the short side of the window opening, thus reinforcing the window opening. The top of the second cap-shaped beam is attached to the second angled beam, and the bottom of the second cap-shaped beam is attached to the first top surface of the first rectangular beam. The top surface of the first rectangular beam is horizontally fixed to a second flat plate with small notches on both sides. Several parallel first channel steels are arranged on the second side of the first rectangular beam and the bottom of the second flat plate. The second end face of the first channel steel is attached to the second side of the first rectangular beam, and the third end face of the first channel steel is attached to the fourth side of the second rectangular beam. The top surface of the second rectangular beam is attached to the bottom surface of the second flat plate. The second rectangular beam is slightly longer than the first rectangular beam. This forms a robust second platform perpendicular to the first flat plate. A rectangular third flat plate, several second channel beams, and two third channel beams are vertically fixed to the bottom surface of the second rectangular beam to support the second platform. The height of the third flat plate is equal to the lengths of the second and third channel beams. The openings of the two third channel beams face the fourth end face of the second rectangular beam and are flush with it to increase the connection strength with the side wall of the matching box. Several second channel beams are evenly distributed between the two third channel beams, with their openings facing the third flat plate and fitting against it to form a closed structure, increasing... The rigidity of the third plate is such that the height of the second channel beam's cross-section is equal to the width of the third channel beam's cross-section, ensuring that the fifth side of the second channel beam and the seventh side of the third channel beam can fit against the side of the second channel steel. The first platform, composed of the longer second channel steel, the shorter and third channel steel, and the narrower fourth plate, is horizontally fixed. The first platform is significantly lower than the second platform. The fourth plate is located on top of the first platform. Several fourth channel steels are vertically fixed at the bottom of the first platform, providing multi-point and balanced support for the first platform. The bottom edge of the third plate, the bottom surface of the second channel beam, the bottom surface of the third channel beam, and the bottom surface of the fourth channel steel are flush, facilitating positioning and assembly on the matching box frame.This invention uses a vertically arranged first and third flat plate to separate the longitudinal space of the housing, and a horizontally arranged second platform to separate the vertical space of the housing. This creates a rectangular cavity with an outward opening formed by the lower part of the end wall, the supporting base frame, and the side walls, facilitating the installation of equipment for outdoor use. The second platform can accommodate seating and other devices, improving the space utilization of the housing. The first platform, being close to the base frame, can serve as a step leading to the second platform, facilitating personnel access. Windows are installed in the openings to allow for lighting inside the housing and observation of the outside environment. The outer side of the end wall is flat and aesthetically pleasing.

[0031] Combination Figures 1-5 The first to fourth flat plates are made of rectangular plates. The first flat plate is wider and taller. A rectangular window hole is made in the middle of the first flat plate for installing a window. The four corners of the window hole are rounded to avoid stress concentration and to make the window hole look better. The second flat plate has small L-shaped notches on both sides to match the columns of the box. The fourth flat plate is narrower to avoid taking up too much space inside the box.

[0032] Combination Figures 1-5 The first and second triangular beams are made of sheet metal. The first triangular beam has a smaller cross-sectional size and is used to connect the first flat plate and the column of the matching box body to avoid large welding deformation between the column and the first flat plate due to the rounded weld. The second triangular beam has a larger cross-sectional size and is used to connect the top cover of the matching box body to seal the box body and transfer the load.

[0033] Combination Figures 1-6 The first to fourth cap-shaped beams are made of sheet metal. Their openings are welded to the first flat plate to form a closed structure, which improves the rigidity of the first flat plate and reduces the welding deformation between the two. The heights of the cross sections of the first to fourth cap-shaped beams are all equal, i.e., Hmx1 = Hmx2 = Hmx3 = Hmx4, which facilitates the installation of the inner lining plate on the inside of the end wall.

[0034] Combination Figures 1 to 7 The first to third channel beams are made of sheet metal or profiles. The first channel beam is shorter so that the window opening of the first plate is at a convenient height for observation. The height Hcx2 of the cross-section of the second channel beam is equal to the width Lcx3 of the cross-section of the third channel beam, ensuring that the top surface of the second channel beam and the side surface of the third channel beam can be fixed to the second channel steel of the first platform, increasing the support points of the first platform. The lengths of the second and third channel beams are equal to the height h of the third plate, ensuring that the bottom of the second and third channel beams and the bottom edge of the third plate are flush after assembly.

[0035] Combination Figures 1-5 The first to fourth channel steels are cut from hot-rolled channel steel, with the third channel steel being the longest, the first and fourth channel steels being shorter, and the second channel steel being the shortest.

[0036] Combination Figures 1-5The first rectangular beam and the second rectangular beam are made of sheet metal or rectangular tubes, with the first rectangular beam being slightly shorter than the second rectangular beam.

[0037] Combination Figures 1-9 A first flat plate is vertically arranged to ensure the long side of the window opening is horizontal. A second angular beam, a first cap-shaped beam, a third cap-shaped beam, and a first rectangular beam are sequentially fixed from top to bottom, close to the inner side of the first flat plate and parallel to its side. The bottom edge of the first flat plate overlaps the first side surface of the first rectangular beam. From the center line of this invention to the side surface of the first flat plate, shorter first channel beams, fourth cap-shaped beams, second cap-shaped beams, and first angular beams are symmetrically fixed, intersecting perpendicularly with the second angular beam, first cap-shaped beam, third cap-shaped beam, and first rectangular beam, respectively, forming a grid-like plate-beam structure. The edge of the third cap-shaped beam is flush with the long side of the window opening, and the edge of the second cap-shaped beam is flush with the short side of the window opening, reinforcing the window opening. The top of the second cap-shaped beam is attached to the second angular beam, and the bottom of the first cap-shaped beam is attached to the first top surface of the first rectangular beam. The top of the first rectangular beam... A second flat plate with small notches on both sides is horizontally fixed. Several parallel first channel steels are arranged on the second side of the first rectangular beam and the bottom of the second flat plate. The second end face of the first channel steel is attached to the second side of the first rectangular beam, and the third end face of the first channel steel is attached to the third side of the second rectangular beam. The top surface of the second rectangular beam is attached to the bottom surface of the second flat plate, forming a second platform that is perpendicular to the first flat plate and is solid. The third flat plate, the second channel beam, and the third channel beam are vertically fixed in sequence to the bottom surface of the second rectangular beam to support the second platform. The openings of the two third channel beams face the fourth end face of the second rectangular beam and are flush with the fourth end face of the second rectangular beam, increasing the connection strength with the side wall of the matching box. Several second channel beams are evenly distributed between the two third channel beams. The openings of the second channel beams face the third flat plate and are attached to the third flat plate to form a closed structure, increasing the rigidity of the third flat plate.

[0038] Two second channel steels and several third channel steels perpendicular to the second channel steels are fixed together to form a rectangular frame. The third and fourth flat plates are fixed on the top of the rectangular frame to form a first platform. The sides of the second channel steels face outwards to facilitate their fixation with the second and third channel beams.

[0039] At a position significantly lower than the second platform, the fourth plate of the first platform is made horizontal and upward, and the fifth side of the second channel steel and the seventh side of the third channel beam can be attached to the side of the second channel steel and the top surface of the second channel beam and then fixed. Several fourth channel steels are vertically fixed at the bottom of the first platform to provide multi-point and balanced support for the first platform.

[0040] The method of using this utility model is as follows: The utility model is fixed to the top surface of the box frame, the bottom surface of the top cover and the sides of the two side walls respectively. A window is installed in the second window hole of the end wall to form a box-shaped structure with a rectangular cavity at the outer end. Seats and other equipment can be installed on the second platform to meet the loading requirements of other equipment and goods inside and outside the box.
