Description

Technical Field

[0001] The present invention relates to the technical field of semi-trailer containers, in particular to a semi-trailer container capable of rapid unloading and an unloading operation method thereof. Background Art

[0002] As a modern mode of transportation and an advanced transportation technology, container transportation has long been favored by users for its high efficiency, high quality, low cost, ease of multimodal transport, specialization, and standardization. With the development of the logistics industry, the demand for transporting bulk cargoes such as coal, iron ore, and nickel ore in open-top containers is increasing. However, the open-top containers currently used to transport bulk cargoes such as coal, iron ore, and nickel ore are typically constructed by removing the top panels from 20-foot containers. While these containers meet the requirements for combined road and rail transport and can be unloaded using reach stackers, loaders, and tilters, they are notoriously difficult to transport.

[0003] However, the existing rapid unloading technology of semi-trailer containers still has significant bottlenecks, specifically:

[0004] 1. Excessive reliance on equipment: Unloading requires the use of external equipment such as forklifts, cranes, or dedicated unloading platforms. For example, even when unloading a small amount of cargo, the entire container must be moved or hoisted, significantly reducing flexibility.

[0005] 2. Low efficiency of manual handling: Most of the handling is still done manually, which requires multiple people to move the goods from the box to the door opening piece by piece, which is time-consuming and labor-intensive and easily leads to the risk of work-related injuries.

[0006] 3. Poor site adaptability: Large equipment cannot be deployed in narrow warehouses, unhardened surfaces, and other scenarios, resulting in the failure of the technical solution. Summary of the Invention

[0007] The object of the present invention is to provide a semi-trailer container capable of rapid unloading, so as to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A semi-trailer container capable of rapid unloading comprises a truck, a container being mounted on the truck, electric side doors being provided on both sides of the container, a plurality of sleeves being installed at the bottom of the container, reinforcement seats being plugged in and connected in the sleeves, a memory box being slidably arranged in the container through a sliding assembly, a screw motor drive mechanism being provided above the memory box, a slot being provided on the top of the memory box for movement of the screw motor drive mechanism, a push plate being provided below the screw motor drive mechanism and penetrating through the memory box, the push plate being T-shaped, a slot being provided on the side of the push plate adjacent to the bottom, an inclined slide being plugged into the slot through a plug pipe, a detachable blanking plate being provided at the bottom of the memory box through concave-convex fitting, an electrical cabinet and a refrigeration box being provided at both ends of the container respectively;

The groove plate is arranged above the bottom wall inside the container, and the convex plate is arranged below the memory box. The convex plate and the groove plate cooperate to achieve sliding. The linear motor is arranged above the bottom wall inside the container and is spaced apart from the groove plate. The top of the linear motor is connected to the bottom of the memory box.

[0011] As a further preferred embodiment of the present invention: a support portion is provided at the bottom of the container, the support portion includes an electric cylinder, a motor frame, a servo motor, a diagonal support rod and a friction block. The electric cylinder is arranged at the bottom of the container, the motor frame is arranged below the electric cylinder, the servo motor is arranged in the motor frame and the servo motor extends from the motor frame, the diagonal support rod is inclined and one end is connected to the output end of the servo motor, the friction block is arranged above the diagonal support rod, and the support portion can realize a rotating storage function on the lower support bracket of the container by extending and rotating up and down.

[0012] As a further preferred embodiment of the present invention: an air pump is provided above the memory box, and C-shaped air pipes are provided on the sides of the memory box. The design of the C-shaped air pipe just leaves space for dragging out the blanking plate without affecting the taking and placing of the blanking plate. A lower pipe is provided at the bottom of the memory box, and the air pump is connected to the C-shaped air pipe and the lower pipe, which can be used to blow and clean the bottom of the memory box. A brush is also provided at the bottom of the memory box, and the brush can directly clean the debris.

[0013] As a further preferred solution of the present invention: two air holes are provided in the memory box, so that the cold air in the refrigeration box can be transmitted to the memory box.

[0014] As a further preferred embodiment of the present invention: a method for unloading a semi-trailer container that can unload quickly is characterized in that it includes the following steps in sequence: S1: parking and preliminary alignment, parking the semi-trailer truck at a designated position on the unloading platform, tightening the handbrake to ensure that the vehicle is stable; S2: opening the side door of the container, and operating the control system to open the electric side doors on both sides of the container to completely expose the sides of the storage box; S3: moving out the storage box, the control system activates the linear motor in the sliding assembly, and the linear motor drives the storage box to slide smoothly toward the side door of the container under the guidance of the groove plate through the convex plate at the bottom, usually toward the side of the unloading platform, until most of the storage box is moved out of the container body and the blanking plate at the bottom can be pulled out straight When unloading, it can also serve as a load-bearing device without being pulled out; S4: Expand the reinforcement seat to stabilize the vehicle body, start the support part through the control system, start the servo motor and the electric cylinder, drive the diagonal support rod to rotate and expand to the support position with an inclination outward on both sides, fine-tune the electric cylinder so that the friction block contacts the bottom of the memory box, and slightly lift the memory box to share the hanging load of the truck and prevent the vehicle body from shaking or sinking during unloading; S5: Install the inclined slide plate, insert the insert of the inclined slide plate into the slot hole on the side of the push plate near the bottom, and lock the slot hole with the insert to fix the inclined slide plate to ensure that it is stable and the inclination angle is facing the unloading platform or conveyor belt; S6: Start the pushing mechanism to unload, and the control system starts the screw motor drive mechanism, and the screw motor drives the T-shaped structure to push the push plate along the memory box The slot on the top moves from one end of the inside of the memory box to the other end where the inclined slide is installed. The push plate pushes the goods in the memory box to move in the direction of the inclined slide. The goods are pushed to the inclined slide and slide along the inclined slide to the unloading platform or designated conveying equipment to complete the main unloading process; S7: Remove the blanking plate and preliminary cleaning, release the concave-convex locking mechanism between the blanking plate and the bottom of the memory box, pull the blanking plate out from the bottom of the memory box, start the air pump, and the air pump blows air to the bottom area of ​​the memory box through the C-shaped air pipe and the lower pipe. The air pump blows air to the bottom of the memory box through the pipe. The compressed air flow blows away the debris or dust remaining on the bottom and corners of the memory box, and uses the bristles to loosen and blow out the loosely adhering miscellaneous materials; S8: Clean the inside of the memory box and reset the push plate After the goods are emptied and preliminarily purged, clean the inner wall and bottom of the memory box more thoroughly manually or with tools such as a long-handled brush to remove residues that the air pump failed to completely blow away, control the screw motor drive mechanism to run in reverse, move the push plate to the starting end of the memory box, away from one end of the inclined slide; S9: Disassemble and store the inclined slide, unplug the fixing pin to unlock, pull the inclined slide out of the slot of the push plate, and properly store the inclined slide back to the designated position; S10: Retract the support part, control the servo motor to reverse, rotate the diagonal support rod to retract and remove the reinforcement seat; S12: Final inspection and preparation for departure, check whether all components are reset in place, the side door is closed, the memory box is returned to its position, the support part is folded, and the inclined slide and blanking plate are placed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This design significantly improves the autonomous unloading capabilities and overall operational efficiency of bulk cargo transportation. By integrating a built-in push-plate mechanism, a sliding storage box, and a self-stabilizing support system, it completely eliminates dependence on external equipment such as forklifts and cranes, achieving operational independence for unloading right out of the box. The storage box slides out as a whole, and the inclined slide plate expands the unloading surface. Combined with a T-shaped push plate driven by a screw motor, the forced push of cargo significantly reduces the intensity of manual handling, allowing a single person to efficiently complete the unloading of large quantities of bulk cargo. The unique support design stabilizes the vehicle body through electric adjustment and rotating friction blocks, solving the pain point of poor site adaptability of traditional equipment. At the same time, the quick-release structure of the unloading plate and the coordinated cleaning system of the air pump and brush significantly reduce cargo residue and cleaning time, ensuring rapid recycling of the box. The cold air circulation design of the refrigeration box and air vents further meets the needs of temperature-controlled bulk cargo. The overall technical solution, in a highly integrated and automated manner, simultaneously overcomes efficiency bottlenecks, cost pressures, and scenario limitations, providing a transportation solution that combines flexibility, reliability, and universality for bulk cargo logistics such as coal and ore.

[0035] The design divides the container 2 into a main frame and a slidable built-in storage box 10, and is equipped with an integrated power and actuator to achieve controllable movement of goods in and out of the storage box 10. The controllable movement of the storage box 10 in and out of the container 2 is achieved by using a linear motor 14 to drive the storage box 10 to slide out of the main body of the container 2, greatly expanding the working surface and facilitating cleaning the interior of the container 2.

The connection design of the refrigeration box 5 and the air vent 8 of the storage box 10 realizes cold air circulation.

[0036] This design significantly overcomes the unloading bottleneck of bulk container transport, achieving an efficient, autonomous, and universal operational innovation. Its core value lies in completely eliminating the reliance on large external equipment such as forklifts and cranes. Full unloading can be completed independently using only a conventional unloading platform or a simple site, significantly reducing equipment investment and site constraints. The integrated push plate 15 mechanism and slide-out storage box 10 design transform the traditional labor-intensive handling process into an automated mechanical push, allowing efficient single-person operation, greatly improving operation speed and reducing the risk of work-related injuries. The support section 7 electrically adjusts to adapt to different ground conditions, effectively solving the problem of stable operation on unhardened sites or in confined spaces. The quick-release blanking plate 11 and pneumatic mechanical collaborative cleaning system significantly shorten the cleaning and resetting time of the box, ensuring efficient transportation turnover. Furthermore, the optional refrigeration function expands the transportation scenarios of temperature-controlled bulk cargo. The overall technical solution uses modularization and automation to simultaneously optimize efficiency, cost, and adaptability.
