Description

Technical Field

[0001] This application belongs to the field of container technology, and in particular relates to open-top, self-unloading, unpressurized U-shaped tank containers for dry bulk cargo. Background Technology

[0002] In the field of tank container technology, existing tank containers, as standardized transportation equipment, generally adopt a fully enclosed pressure-bearing structure and are mainly used for multimodal transport of liquids, gases, and powders. However, for the special needs of dry bulk cargo transportation, existing technical solutions have the following unresolved technical problems:

[0003] (1) The closed tank structure of traditional tank containers can only carry fluid media, and its internal baffles, heating pipes and other auxiliary devices are structurally conflicted with the particulate characteristics of dry bulk cargo.

[0004] (2) Existing tank containers lack an automatic unloading mechanism integrated with the tank body, and have failed to overcome the physical limitations of the fully enclosed structure on unloading efficiency, resulting in the technical problem of long unloading time for dry bulk cargo.

[0005] (3) Accumulated pressure can easily form inside the sealed tank, posing a safety risk in cargo transportation scenarios.

[0006] The aforementioned technical deficiencies indicate that existing tank containers have significant room for improvement in terms of structural functionality, operational efficiency, and operational safety when adapting to the needs of dry bulk cargo transportation. There is an urgent need to develop new tank container technology solutions that meet the characteristics of dry bulk cargo transportation. Utility Model Content

[0029] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0030] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0033] Please see Figures 1 to 4As shown in the embodiment of this application, an open-top, self-unloading, unpressurized U-shaped tank container for dry bulk cargo is provided, including a U-shaped tank body 10. Side beams 11 are provided on both sides of the open end of the U-shaped tank body 10, and columns 12 are provided on the periphery. For example, the side beams 11 and columns 12 are used to improve structural strength and enhance the structural stability of the U-shaped tank body 10.

[0034] As an example, the U-shaped tank 10 is also provided with a transverse tie rod 21 connecting the two sides of the U-shaped tank 10. The two ends of the transverse tie rod 21 are also provided with diagonal tie rods 22 to form a triangular structure, which stably supports the two sides of the U-shaped tank 10 and prevents deformation.

[0035] As an example, the bottom of the U-shaped tank 10 is also provided with a cross brace 23 and a longitudinal beam 24 to provide reliable support for the bottom of the U-shaped tank 10.

[0036] As an example, the side beam 11 is a square tube, and the column 12 is an arc-shaped column that extends to the position of the longitudinal beam 24 at the bottom of the U-shaped tank 10.

[0037] In this embodiment, the U-shaped tank 10 has a front door 13 at its front end and a rear door 14 at its rear end. Inside the U-shaped tank 10, an inner front baffle 15 is provided between the front door 13 and the rear door 14, and a lifting device (not shown in the figure) is provided between the front door 13 and the inner front baffle 15. For example, the lifting device is driven by a hydraulic mechanism, and the tank angle is adjusted by hydraulic power output. This embodiment does not specifically limit the hydraulic mechanism, as long as it can lift the front end of the U-shaped tank 10 so that the U-shaped tank 10 can be tilted.

[0038] In this embodiment, the top of the rear door 14 is rotatably connected to the U-shaped tank 10, and a gravity lock 16 is provided on the top of the rear door 14. For example, during transportation, the gravity lock 16 locks to prevent the rear door 14 from rotating. For example, when the U-shaped tank 10 tilts under the action of a hydraulic mechanism, the gravity lock 16 unlocks, and the rear door 14 rotates to achieve automatic unloading. The specific implementation of the rotatable connection between the top of the rear door 14 and the U-shaped tank 10, as well as the specific structure of the gravity lock 16, can be found in related technologies, and will not be elaborated upon in this embodiment.

[0039] In this embodiment, the U-shaped tank 10 is further provided with a top hook 17 and a bottom hook 18. For example, each of the four top corners of the U-shaped tank 10 is provided with a top hook 17 for a crane to lift the container. For example, each of the four bottom corners of the U-shaped tank 10 is provided with a bottom hook 18 for fixed connection with a transport vehicle during transportation. For example, when the bottom hook 18 at the rear door 14 of the U-shaped tank 10 is fixedly connected to the transport vehicle, it can also rotate around the connection point, allowing the lifting device to smoothly lift the front end of the U-shaped tank 10 and achieve tank angle adjustment.

[0040] In this embodiment, a rear baffle 19 is also provided at the bottom of the rear end of the U-shaped tank 10. The rear baffle 19 is rotatably connected to the bottom of the U-shaped tank 10 and fixed by a rotary latch lock 20. For example, the rotary latch lock 20 includes a locking arm provided at the rear end of the U-shaped tank 10. The locking arm is provided with a hook groove, and the rear baffle 19 is provided with a pin. By rotating the locking arm, the hook groove engages with the pin to lock and unlock the rear baffle 19.

[0041] Therefore, the lifting device provided in this application embodiment is used to lift the front end of the U-shaped tank 10 (for example, before lifting, the bottom hook 18 of the front end of the U-shaped tank 10 can be disconnected from the transport vehicle), so that the U-shaped tank 10 rotates and tilts around the bottom hook 18 and automatically opens the rear door 14 to achieve self-unloading.

[0042] The lockable, open-top, self-unloading, pressureless dry bulk cargo U-shaped tank container uses an open-top U-shaped tank 10 to load dry bulk cargo, achieving pressureless loading and eliminating safety hazards. It is reinforced with side beams 11 and columns 12 to improve the structural strength of the container. By installing a lifting device between the inner front panel 15 and the front door 13, and a gravity door lock 16 at the rear door 14, when the lifting device is used to lift the front end of the U-shaped tank 10, the U-shaped tank 10 rotates and tilts around the bottom hook 18 at the rear door 14 to achieve self-unloading, improving unloading efficiency.

[0043] In some embodiments of this application, the front door 13 adopts a double-door structure, for example, including two door panels 131, which are respectively hinged to the front end of the U-shaped tank 10, and the edges of the two door panels 131 are provided with quick-clamping devices 132. For example, the quick-clamping device 132 includes a locking rod provided on the door and a latch provided at the front end of the U-shaped tank 10. The locking rod and the latch are connected by a snap-fit ​​connection. For specific implementation methods, please refer to relevant prior art implementations, which will not be repeated here.

[0044] In some embodiments of this application, the open-top, self-unloading, pressureless dry bulk U-shaped tank container also includes an optional electric tarpaulin. By covering the opening of the U-shaped tank 10 with the electric tarpaulin, dust and raindrops can be prevented from mixing into the loaded dry bulk cargo.

[0045] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to 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 application, and should all be included within the protection scope of this application.
