Description

Technical Field

[0001] This utility model relates to the field of container equipment technology, and in particular to a side-tipping container transported by a skeleton semi-trailer. Background Technology

[0002] A shipping container, also known as a cargo container, is a standardized, reusable, giant metal box used for multimodal transport (sea, rail, and land), and is the cornerstone of the modern global trade and logistics system. A skeleton semi-trailer is a complete transport vehicle composed of two main parts: a "skeleton vehicle (tractor unit)" and a "semi-trailer," which carries a container to complete the transportation and transshipment of goods.

[0003] Currently, the traditional containers carried by heavy container semi-trailers mainly rely on external lifting equipment to complete loading and unloading operations, resulting in low unloading efficiency. When transporting bulk cargo such as sand, gravel, and coal, it is necessary to rely on specialized equipment such as gantry cranes and forklifts. However, in remote construction sites or scenarios lacking lifting equipment, unloading cannot be completed independently, which seriously affects transportation turnover efficiency.

[0004] In addition, there is a problem of insufficient loading and unloading convenience: traditional box locks are mostly single bolt structures, which are cumbersome to operate, and the door design is fixed, which cannot flexibly adapt to the loading and unloading needs of different goods. Utility Model Content

[0005] This application provides a side-tipping container transported by a skeleton semi-trailer, which can effectively improve unloading efficiency and meet the needs of rapid unloading of different goods.

[0006] This application provides a side-tipping container transported by a skeleton semi-trailer, including a container body, multiple hydraulic cylinders, and matching supports. The container body is provided with a side door, which includes multiple sets of double-opening main door panels. Each main door panel has independently openable and closable sub-door panels. At least one of the sub-door panels has an observation window near its upper part. The observation window is fitted with transparent glass in a sealed manner. The container body has a discharge side and a tipping side on its two sides along its length. The bottom of the container body on the discharge side is provided with a hinge element for hinged to the vehicle body. The tipping side of the container body overlaps the top of the vehicle body. The multiple hydraulic cylinders are distributed sequentially along the length of the container body at the bottom of the container body. The hydraulic cylinders are mounted on the top of the vehicle body through the matching supports, and the telescopic ends of the hydraulic cylinders are connected to the container body.

[0007] In one possible implementation, the sub-door panel has an openable and closable protective plate on the outside of the transparent glass. The protective plate has a hinged end and a movable end opposite to each other. The protective plate is hinged to the sub-door panel through the hinged end, and a snap-fit ​​handle that can be rotated and moved vertically is connected to the movable end. The sub-door panel has a first snap-fit ​​groove that cooperates with the snap-fit ​​handle. The first snap-fit ​​groove is a top-open groove.

[0008] In one possible implementation, the main door panel is provided with a sub-door panel frame, and the sub-door panel is connected to the top of the sub-door panel frame in a hinged manner via a hinge structure. The sub-door panel frame is provided with a plurality of second snap-fit ​​grooves at intervals on the sides and bottom. The sub-door panel is provided with a snap-fit ​​plate that cooperates with the second snap-fit ​​grooves and is capable of rotating in the vertical direction.

[0009] In one possible implementation, the sub-door panel has a sealing element on the side facing outwards from the box, for forming a seal with the main door panel when closed.

[0010] In one possible implementation, the transparent glass is laminated glass, consisting of two layers of tempered glass, with a PVB film sandwiched between the two layers of tempered glass.

[0011] In one possible implementation, electric heating wires are embedded in both layers of tempered glass, and a rechargeable battery is integrated on the outer side of the sub-door panel, the rechargeable battery being electrically connected to the electric heating wires in the two layers of tempered glass.

[0012] In one possible implementation, at least one of the multiple sub-door panels is provided with an openable and closable material handling window.

[0013] Beneficial effects: Compared with the prior art, the side-tipping container transported by the skeleton semi-trailer provided in this application is not only equipped with double-opening main doors, but also with sub-doors. It is not necessary to open the entire huge and heavy unloading door every time a small amount of cargo is unloaded, which can reduce the intensity and time of operation. At the same time, the hydraulically driven side-tipping unloading can save unloading time and improve unloading efficiency and transportation turnover efficiency. The second snap-fit ​​slot and snap-fit ​​plate work together to firmly fix the sub-door panel to the main door panel, while also making it easy to quickly open the sub-door panel from the main door panel, making operation convenient. The observation window and transparent glass allow for easy initial observation of the goods inside the container, while the material retrieval window facilitates quick material retrieval or sampling, resulting in high work efficiency and low labor intensity.

[0014] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0020] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0021] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms, such as those defined in commonly used dictionaries, shall be interpreted as having a meaning consistent with their meaning in the context of the relevant art and shall not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] refer to Figures 1 to 4This application provides a side-tipping container transported by a skeleton semi-trailer, including a container body 10, multiple hydraulic cylinders 20, and matching supports 30. The container body 10 is provided with a side door, and the side door includes multiple sets of double-opening main door panels 11. The number of sets of main door panels 11 can be flexibly adjusted according to the length of the container body 10 and the width of the main door panels 11. Each main door panel 11 has independently openable and closable sub-door panels 12. At least one of the sub-door panels 12 has an observation window 104 near the top. The observation window 104 is fitted with transparent glass in a sealed manner, thereby allowing direct observation of the goods inside the container without opening the sub-door panels 12 or the main door panels 11, reducing labor intensity and making it convenient to use. The observation windows 104 can be distributed on both sides of the container body 10, or only on one side of the container body 10. Furthermore, there can be only one observation window 104 or multiple observation windows 104. The observation window 104 is located near the sub-door panel 12 or the upper part of the box body 10, which can reduce the lateral pressure exerted on the transported goods and make it safer to use. The box body 10 has an unloading side 101 and a tilting side 102 on both sides along its length. The bottom of the unloading side 101 of the box body 10 is provided with a hinge element 13 for hinged to the vehicle body 40, so that the box body 10 can be tilted around the hinge point for unloading. The tilting side 102 of the box body 10 overlaps the top of the vehicle body 40. In addition, a plurality of hydraulic cylinders 20 are distributed sequentially along the length of the box body 10 at the bottom of the box body 10. At the same time, the hydraulic cylinders 20 are mounted on the top of the vehicle body 40 through the matching support 30, and the telescopic ends of the hydraulic cylinders 20 are connected to the box body 10.

[0024] Therefore, the side-tipping container transported by the skeleton semi-trailer provided in this application is equipped with both a main door panel 11 and a sub-door panel 12. Depending on the amount of unloading and the size of the cargo, it is possible to flexibly choose to unload by opening the main door panel 11 or the sub-door panel 12. It is not necessary to open the entire huge and heavy unloading door every time a small amount of cargo is unloaded, which can reduce the intensity and time of operation. At the same time, the side-tipping unloading is driven by the hydraulic cylinder 20 at the bottom of the container body 10 (i.e. the top of the vehicle body), which can save unloading time. Even in remote construction sites or in scenarios lacking hoisting equipment, unloading can be completed independently, which can improve unloading efficiency and transportation turnover efficiency.

[0025] It should be noted that the double-leaf main door is a conventional technology, employing a traditional left and right double-leaf door design. Each door can open outwards independently by nearly 180 degrees, allowing the rear of the container to be completely open. Generally, the container body 10 is hinged to the relatively far outer side via a hinge, while the lock head (cam lock tongue) is engaged by a locking rod on the relatively close inner side, locking in place with the lock groove.

[0026] In some embodiments, the sub-door panel 12 is provided with an openable and closable protective plate 14 on the outside of the transparent glass. The protective plate 14 has a hinged end and a movable end, wherein the protective plate 14 is hinged to the sub-door panel 12 through the hinged end, and the protective plate 14 is connected to a vertically rotatable latching handle 15 at the movable end. Correspondingly, the sub-door panel 12 is provided with a first latching groove 106 that cooperates with the latching handle 15, and the first latching groove 106 is a top-open groove. In this way, during the normal transportation of the skeleton semi-trailer, the protective plate 14 can continuously protect the transparent glass from being impacted by external objects, or from being contaminated or blocked by dust, other pollutants, etc., so that the contents inside the box can be viewed through the transparent glass at any time. At the same time, it can also play a role in confidentiality, preventing non-staff or work-related personnel from viewing the contents inside.

[0027] Preferably, the protective panel 14 has the same and compatible texture structure as the sub-door panel 12, which can serve as a camouflage, better protect the items inside the box, and prevent them from being spied on by unauthorized personnel.

[0028] In some embodiments, the main door panel 11 is provided with a sub-door panel frame 111. The sub-door panel 12 is hinged to the top of the sub-door panel frame 111 via a hinge structure 121. The sub-door panel frame 111 has multiple second locking slots 103 spaced apart on its sides (either side or both sides, depending on installation needs and space) and bottom. Correspondingly, the sub-door panel 12 has locking plates 122 that engage with the second locking slots 103 and can rotate vertically. Thus, when the sub-door panel 12 is closed, simply rotating the locking plates 122 sequentially to engage them with the second locking slots 103 completes the locking and fixing of the sub-door panel 12 onto the main door panel 11. When the sub-door panel 12 needs to be opened separately, the locking plates 122 are rotated sequentially to disengage from the second locking slots 103, making operation convenient.

[0029] In some embodiments, the sub-door panel 12 is provided with a sealing element, such as a sealing ring, on the side facing outward of the box, for forming a seal with the main door panel 11 when closed, so as to ensure the overall sealing performance of the box 10 and facilitate the transfer and transportation of goods.

[0030] In some embodiments, the transparent glass is laminated glass, consisting of two layers of tempered glass with a PVB film sandwiched between them. During use, even if the transparent glass shatters due to a strong impact, the glass fragments will adhere firmly to the PVB film, preventing them from flying and causing injury, thus ensuring operator safety.

[0031] More preferably, both layers of tempered glass are embedded with electric heating wires, and a rechargeable battery is integrated on the outer side of the sub-door panel 12. The rechargeable battery is electrically connected to the electric heating wires in the two layers of tempered glass, thereby enabling the transparent glass to have anti-fog / defrost capabilities, maintaining a clear field of vision, and not affecting viewing even in winter when there is a large temperature difference between the inside and outside.

[0032] In some embodiments, at least one of the multiple sub-door panels 12 is provided with an openable and closable material retrieval window 105, which facilitates quick material retrieval or sampling, resulting in high work efficiency and low labor intensity. Generally, only one material retrieval window 105 needs to be provided.

[0033] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
