Description

Technical Field

[0001] This utility model relates to the field of highway transportation technology, and in particular to a self-unloading, anti-tipping transfer container for bulk cargo transportation. Background Technology

[0002] With the increasing use of bulk cargo such as grain by-products, feed ingredients, agricultural and forestry scraps, lightweight building materials, and recycled materials in road transportation, open-top bulk containers have become a commonly used loading unit in the logistics transportation system. Existing bulk containers in road transportation scenarios typically need to balance loading capacity, structural stability, and rapid unloading capability, with bottom unloading and side-door unloading being common methods for unloading bulk cargo. However, in actual use, the self-unloading process still faces several structural safety risks and efficiency bottlenecks.

[0003] I. Existing bulk cargo self-unloading methods mostly rely on tilting the entire truck bed or container to discharge materials. In situations with steep road slopes, limited site space, or insufficient foundation bearing capacity, tilting the entire load can easily cause the vehicle to tip over or overturn.

[0004] Second, traditional open-top containers generally use fixed bottom plates and do not have the ability to actively unload. Unloading requires external machinery for lifting or manual tools to assist, resulting in low unloading efficiency. Furthermore, uneven accumulation of bulk cargo inside the container can lead to localized stress concentration, bottom plate fatigue, and structural deformation, thus reducing the service life of the container.

[0005] To address this, a self-unloading, anti-tipping transshipment container for bulk cargo transport by road is proposed. Utility Model Content

[0006] In view of this, the present invention provides an open-top self-unloading anti-tipping transshipment container for road transport of bulk cargo, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model is as follows: a road transport bulk cargo open-top self-unloading anti-tipping transfer container, including an open-top container, wherein the open-top container includes a container frame;

[0008] The inner wall of the container frame is fixedly connected with two partitions at equal intervals along the length direction, dividing the interior of the open-top container into three independent areas;

[0009] Each area is equipped with an anti-tipping mechanism, which includes two symmetrically arranged support beams. Several support frames are fixedly connected to the edge of each support beam. One end of several support frames is fixedly connected to the support beam. The bottom of the box frame is hinged to the support frame through several hinge seats.

[0010] Several staggered cross braces are fixedly connected between the two support beams to form the load-bearing skeleton of the base plate.

[0011] A bottom beam support is fixedly installed at the bottom of the box frame. Two hinge seats are respectively provided between the two support beams and the bottom beam support. A hydraulic cylinder is hinged to the bottom beam support through the corresponding hinge seat. The piston rod end of the hydraulic cylinder is hinged to the corresponding hinge seat on the support beam.

[0012] An integral tilting bottom plate is fixedly connected to the upper side of several support frames, support beams and several cross braces. The tilting bottom plate is lifted as a whole by the hydraulic cylinder to realize the unloading of bulk cargo in the open-top container, while the container frame itself remains horizontal and does not tilt.

[0013] More preferably, the two sides of the box frame are provided with a number of side doors, and each side door is provided with a door lock assembly between itself and the box frame.

[0014] In a further preferred embodiment, the front end of the box frame is provided with a front end cover plate, and three hydraulic oil tanks are arranged below the front end cover plate. The hydraulic oil tanks are provided with hydraulic tank doors on the front side for inspection and maintenance.

[0015] More preferably, the rear end of the box frame is provided with a rear end baffle door, and a toolbox is installed between the lower part of the rear end baffle door and the bottom of the box frame.

[0016] In a further preferred embodiment, a reinforcing beam is provided through the plurality of the support frames to enhance the overall structural strength of the flipping base plate.

[0017] The present invention has the following advantages due to the adoption of the above technical solution:

[0018] I. This utility model features a tilting bottom plate structure inside the container, consisting of support beams, support frames, reinforcing beams, and cross braces. A hydraulic cylinder drives the bottom plate to partially tilt inside the container, eliminating the need for the entire container or transport vehicle to tilt laterally. This fundamentally eliminates the center of gravity shift problem caused by the overall lifting of traditional dump trucks. Even under unfavorable conditions such as slopes, soft ground, or restricted areas, the container maintains a horizontal posture, effectively avoiding safety risks such as tilting and overturning, and improving the stability and operational safety of road bulk cargo transportation.

[0019] II. The tilting bottom plate of this utility model is an independent internal unloading mechanism that can achieve active unloading through hydraulic drive, without relying on external lifting equipment or manual tools, which significantly improves unloading efficiency. The tilting bottom plate is composed of a multi-point supported skeleton structure, which has high rigidity and uniform stress characteristics when carrying bulk cargo, and can avoid deformation of the bottom plate due to local concentrated load. Its good structural stability not only ensures the smooth and continuous unloading process, but also helps to extend the service life of the container and improve long-term operational reliability.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, this utility model embodiment provides a road transport bulk cargo open-top self-unloading anti-tipping transfer container, including an open-top container 10. The open-top container 10 is composed of a container frame 11 forming a basic load-bearing skeleton. The container frame 11 is welded from a rectangular steel structure to form a container body with an open top.

[0030] The inner wall of the box frame 11 has two partitions 16 arranged at intervals along the length direction and fixedly connected. The partitions 16 divide the interior of the box into three independent areas: front, middle and rear. This partition structure not only improves the uniform distribution of the force on the bottom plate, but also facilitates the arrangement of independent anti-tipping mechanisms 20 in each area.

[0031] The same anti-tipping mechanism 20 is set in all three areas. Two support beams 27 are arranged along the length of the container in each area. The two support beams are arranged symmetrically from left to right. The support beams 27 are made of rectangular tubing and are mainly used to support the tilting bottom plate 21.

[0032] Several support frames 24 are fixedly connected to the edge of each support beam 27 along the length direction. One end of the support frame 24 is connected to the support beam 27 by welding, and the other end is hinged to the box frame 11 through multiple first hinge seats at the bottom longitudinal beam of the box frame 11.

[0033] The hinged connection structure of the first hinge seat allows the support frame 24 to swing around the first hinge seat during the flipping and lifting of the base plate, thereby ensuring that the support beam 27 does not experience stress concentration during lifting and improving the stability of the flipping action.

[0034] Several staggered cross braces 28 are arranged between the two support beams 27. The cross braces 28 are fixedly connected between the two support beams 27 by welding to form a grid-like load-bearing frame. The function of the cross braces 28 is to provide surface support for the tilting bottom plate 21, improve the overall rigidity of the tilting bottom plate 21, and ensure the stability of bulk cargo during transportation.

[0035] The bottom of the box frame 11 is fixedly connected to the bottom beam support 17. The bottom beam support 17 is a component that bears the reaction force of the hydraulic cylinder 23. Its position is in the center, which can make the thrust of the hydraulic cylinder 23 evenly distributed to the left and right support beams 27. A second hinge seat is provided between each support beam 27 and the bottom beam support 17 for mounting the hinge point of the hydraulic cylinder 23. The cylinder body end of the hydraulic cylinder 23 is hinged to the bottom beam support 17 through the second hinge seat, and its piston rod end is hinged to the second hinge seat on the support beam 27.

[0036] When the hydraulic cylinder 23 extends: the piston rod pushes the support beam 27 to rotate upward around the first hinge seat, and the cross brace 28 and the support frame 24 are raised synchronously. The upper sides of the multiple support frames 24, support beams 27 and cross braces 28 are welded with an integral flipping bottom plate 21. The integral flipping bottom plate 21 forms an inclined surface to realize the unloading of bulk materials by their own weight.

[0037] When the hydraulic cylinder 23 retracts, the tilting base plate 21 falls back to the horizontal position, restoring the open-top container 10 to its transport state.

[0038] In this embodiment, in order to realize the lifting action of the flipping bottom plate 21, the front end area of ​​the open-top container 10 is provided with a hydraulic system, including multiple hydraulic oil tanks 151 fixedly arranged below the front end of the container frame 11, hydraulic cylinders 23 installed between the bottom beam support 17 and the support beam 27, and a hydraulic control system connected thereto. The hydraulic oil tanks 151 serve as oil storage devices for the entire hydraulic system, used to store hydraulic oil and provide a stable oil source to the hydraulic pump. During the operation of the hydraulic cylinders 23, the returned oil returns to the hydraulic oil tanks 151 through the return oil pipeline, forming a closed loop.

[0039] A reinforcing beam 22 is fixed between several support frames 24. The reinforcing beam 22 is used to connect adjacent support frames 24 to enhance the overall structural strength of the flipping base plate 21 during transportation and flipping.

[0040] The front end of the box frame 11 is provided with a front end upper sealing plate 18, and three hydraulic oil tanks 151 are arranged below the front end upper sealing plate 18. The front side of the hydraulic oil tank 151 is provided with a hydraulic tank door 15 for inspection and maintenance.

[0041] In operation, under normal transportation conditions, the tilting bottom plate 21 remains horizontally laid, with its upper surface directly bearing the weight of the bulk materials. The support frame 24, support beam 27, and cross brace 28 below together form the overall load-bearing frame at the bottom of the container. The bulk load is evenly transferred to the container frame 11 through the grid-like beam structure, thus ensuring that even if the vehicle encounters road bumps, uneven load impacts, or local accumulation of bulk materials during vehicle operation, the bottom plate will not undergo significant deformation or local sinking, ensuring the structural stability and lifespan of the container transportation. The hydraulic drive method in this embodiment is a mature existing technology that can be selected and connected as needed, so it will not be described in detail here.

[0042] When unloading is required, the driver or operator activates the hydraulic control system, causing the hydraulic cylinder 23 installed between the bottom beam support 17 and the support beam 27 to start working. After being pressurized, the hydraulic cylinder 23 extends, with the cylinder end serving as a fixed fulcrum via the second hinge seat, while the piston rod end pushes outward and applies force to the support beam 27, causing the support beam 27 to flip upward around the rotation point formed by the first hinge seat between its lower end and the box frame 11. As the support beam 27 rises, the support frame 24 on it swings synchronously around the hinge point, thus preventing structural interference or constraint. At the same time, multiple cross braces 28, as the transverse skeleton connecting the support beam 27, transmit the flipping motion of the support beam 27 to the flipping bottom plate 21 as a whole, so that the flipping bottom plate 21 keeps rising synchronously, at the same amplitude, and smoothly to one side throughout the entire width range, gradually forming an inclined unloading slope.

[0043] Once the tilt angle of the tilting bottom plate 21 reaches the set value, the operator opens the side door 12 located on the side of the container frame 11 according to the unloading requirements. At this time, the bulk materials inside the open-top container 10 naturally slide along the tilt direction of the tilting bottom plate 21 under the action of gravity, and the bulk cargo will be discharged from the opened side door 12 in a continuous and uniform manner, achieving directional unloading. During the entire unloading process, only the bottom plate structure is tilted, and the container frame 11 remains horizontal and does not tilt. It is not necessary to lift the vehicle or tip the entire container over to unload the bulk cargo, thereby reducing the risk of tipping over due to the shift of the center of gravity during unloading of traditional side-tipping dump trucks.

[0044] After the bulk cargo is emptied, the operator shuts off the hydraulic system, causing the hydraulic cylinder 23 to gradually retract. The piston rod slowly descends under the combined action of hydraulic backflow and the weight of the base plate, allowing the support beam 27 to return to its initial horizontal position via the first hinge seat. The cross brace 28 drives the tilting base plate 21 to fall synchronously until it returns to its original horizontal plane. Finally, the tilting base plate 21, support frame 24, and support beam 27 form a stable load-bearing structure again, and the entire unloading cycle is completed and the system re-enters the transportation state.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
