Description

Technical Field

[0001] The invention belongs to the technical field of containers, and in particular relates to an assembled side-opening door box and a transport vehicle. Background Art

[0002] As an advanced means of transportation, containers have been widely used around the world. Compared with traditional loading and transportation methods, containers have many advantages such as safety and reliability, flexible transportation, fast and convenient, economical and practical, and green and environmentally friendly. They are an important multimodal transport equipment in modern logistics and transportation. At the same time, vans occupy a dominant position in road transportation and are widely used to transport various boxed and bulk goods.

[0003] With the development of modern logistics technology, manufacturing enterprises and logistics companies are paying more and more attention to how to improve the efficiency of cargo loading and unloading and reduce logistics transportation costs. At present, logistics transportation is mainly based on container and van transportation. The container adopts a frame structure, which consists of left and right side walls, end faces, box top, box bottom and a pair of box doors. The compartment of the van is mostly a closed compartment structure with a rear-end opening door.

[0004] However, the existing container and van structures have some limitations. The container adopts a standardized design. When loading, the four corner pieces at the bottom bear the load. In order to ensure sufficient strength reserve, the lightweight structure and plate thickness of the frame beam have reached the limit, and there is little room for weight reduction optimization. The truck compartment is usually connected to the frame as a whole. Once the door frame, floor and other structures are damaged or the compartment needs to be replaced, the entire vehicle needs to be repaired, which increases the operating cost of the vehicle.

[0005] In addition, the structure of containers and vans determines that the cargo loading and unloading method is single-end entry and exit, which brings some efficiency problems. Manual loading and unloading is time-consuming and labor-intensive, and the use of forklifts is prone to damage the box floor, increasing maintenance and repair costs. In the process of cargo loading and unloading and transshipment, it mainly relies on forklifts or manual handling, and dedicated automated facilities and equipment have not yet been maturely applied in the market, which greatly restricts the efficiency of the loading and unloading process. Especially during peak periods with high demand for goods, there are often problems such as labor shortages, rising labor costs, and product stacking.

[0013] In a preferred embodiment of the present invention, an arc-shaped curling edge and a notch for avoiding the handle are provided at the lower part of the door panel. When the side door is closed, the curling edge is pressed against the longitudinal beam at the bottom of the box body by the support rod body and the two are kept in close contact.

[0014] In a preferred embodiment of the present invention, the length of the brace is The length of the support rod is L, the longitudinal length of the door panel is a, and the height of the door panel is b.

[0015] In a preferred embodiment of the present invention, the box frame is provided with a buckle which is engaged with the handle to limit the box frame.

[0016] In a preferred embodiment of the present invention, the support rod and the double-headed connecting pin are rotated in a positive and negative direction within a range of 90° around the center of the rivet.

[0017] The invention also discloses a transport tool, comprising a box body, wherein the box body is an assembled side-opening door box body.

[0018] The beneficial effects of the present invention are:

[0019] The assembled side-opening door box of the present invention has achieved remarkable results in improving cargo loading and unloading efficiency, enhancing structural stability, and improving operational convenience through innovative structural design and careful detail processing, providing an excellent solution for the field of modern logistics and transportation. The present invention reasonably arranges a number of side-opening doors on the side of the box, and the loading and unloading method can realize both single-end entry and exit and full-open side door loading and unloading, effectively improving cargo loading and unloading efficiency. The side door is easy to open or close, and can be applied in a variety of operating scenarios, taking into account cargo loading and unloading and transportation safety. The fully open side door loading and unloading solves the problems of low single-end loading and unloading efficiency, difficulty in cargo stacking, narrow working space, and damage to the bottom plate when forklifts enter and exit the box in the prior art.

[0020] First, the present invention greatly improves the flexibility and efficiency of cargo loading and unloading by arranging a side door unit that can be rotated and opened along the longitudinal axis of the carriage frame on at least one side of the carriage frame. Each side door unit includes at least one side door, which is connected to the carriage frame by a rotating hinge and equipped with a strut assembly, so that the side door opening operation is simple and reliable. The design of the central axis of the rotating hinge and the central axis of the strut assembly being arranged vertically in different planes further enhances the stability and service life of the structure.

[0021] Secondly, the preferred three-side door design, including the symmetrically arranged side doors and the middle side door, provides more loading and unloading options. The side doors on both sides are equipped with complete door panels, hinges, strut assemblies and fixed lock seats, while the design of the middle side door cleverly avoids the strut assemblies on both sides, achieving compactness of structure and completeness of functions. This design not only increases the convenience of loading and unloading, but also ensures the strength and stability of the overall structure.

[0022] Furthermore, the support rod assembly of the present invention is exquisitely designed, including a support rod with a rod end lock, a double-headed connecting pin, a rotating pin, and a fixed clamping seat. The connection and arrangement between these components are carefully designed to ensure the flexibility and reliability of the support rod assembly. For example, the support rod can be rotated 90 degrees around the rivet, providing sufficient space for operation. At the same time, the fixed lock seat provided on the vehicle frame can be plugged and matched with the rod end lock to achieve a stable fixation of the support rod assembly.

[0023] In addition, the curved edge and the handle-avoiding notch at the bottom of the door panel are not only beautiful and practical, but also can be pressed against the longitudinal beam at the bottom of the box by the support rod when the side door is closed, ensuring good sealing. The handle set in the middle of the support rod cooperates with the buckle on the box frame, further enhancing the convenience and safety of operation.

[0024] Finally, the invention also optimizes the length of the support rod to ensure that there is enough operating space when the side door is opened, thereby improving loading and unloading efficiency and safety. This assembled side-opening door box can not only be used as an independent product, but can also be integrated into various transportation tools, greatly expanding its application range.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention (including the preferred technical solution) is further described in detail below by means of the accompanying drawings and by listing some optional embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 11 As shown, the present invention provides an assembled side-opening door box, including a box frame, a bottom cover crossbeam, a side door, a support rod assembly and a mounting bracket. By arranging positioning devices at the four corners of the bottom of the box frame and a groove-shaped structure of the bottom crossbeam, reliable assembly positioning of the vehicle and the box and uniform load distribution are achieved. A number of side-opening doors are reasonably arranged on the side of the box, and the loading and unloading method can realize both single-end entry and exit and full-open side door loading and unloading, effectively improving the efficiency of cargo loading and unloading, and the side door is easy to open or close.

[0040] The box body of the present invention is the main frame mechanism, and the support rod assembly is the side door locking / opening mechanism. By rotating and adjusting the lock buckle at the end of the support rod, it is locked with the fixed lock seat on the box body frame to realize opening or closing of the side door, thereby facilitating rapid loading and unloading operations on the side of the box body.

[0041] The box of the present invention is composed of a box frame, a bottom cover crossbeam, a side door, a strut assembly and a mounting support. Four longitudinal load-bearing beams are arranged at the four corners of the box frame, and two vertical beams and two horizontal beams are arranged on the four sides of the front and rear end walls. The two ends of each longitudinal load-bearing beam are connected at right angles to the two adjacent end vertical beams / crossbeams. Devices with positioning holes are respectively arranged at the four corners of the bottom of the box, preferably using container corner fittings, and corresponding fixing pins are arranged on the transport frame to connect and position them. The bottom cover crossbeam of the box is a concave structure, and the height difference h between the middle concave surface and the two end planes is preferably 10mm to 20mm. The middle concave surface is evenly in contact with the upper plane of the vehicle underframe beam, and the convex planes at the two outer ends are in contact with the step planes set on the upper plane of the outer end of the vehicle underframe. This structure realizes uniform loading of the box, which can improve the problem of concentrated force on the four corner fittings of the bottom surface of the existing container. The uniform loading of the bottom surface of the box is more conducive to lightweight design and can also meet the overall structural support function. The four-corner positioning devices at the bottom of the box and the concave bearing structure of the crossbeam are conducive to assembly positioning, which can not only ensure that the mechanical connection strength between the box and the vehicle is firm and reliable, but also make the assembly and replacement between the two simple and easy to operate.

[0042] In addition, a number of support rod positioning holes are provided on the end corner vertical beams and side vertical beams of the box frame. The positions of the holes are determined according to the length of the support rod and the door opening angle. Their function is to lock and support the end of the support rod after the side door is opened.

[0043] The box frame of the present invention adopts a solid structural design. Four longitudinal load-bearing beams are arranged at the four corners of the vertical direction, and two vertical beams and two horizontal beams are arranged at the four sides of the front and rear end walls. The two ends of each longitudinal load-bearing beam are connected to the two adjacent end vertical beams / cross beams at right angles to form a stable three-dimensional frame structure.

[0044] The side door of the present invention is arranged on one side of the box body, and can also be arranged on both sides. The solution of the present invention is to arrange two sets of side door units on one side of the box body, and each set of side door units includes three side doors. The length of the support rod is preferably selected according to the total longitudinal length of the box body. When the length of the support rod is L, the longitudinal length of the side door plate is a, and the height is b, the preferred length of the support rod is Ensure that the angle between the side door panel and the side wall is greater than or equal to 90° when the support rod is supported. The purpose of this setting is to reserve operating space for opening the door to load and unload goods and improve work efficiency. The side door unit is equipped with door 1, door 2 and door 3, of which door 1 and door 3 are left-right symmetrical parts, both including door panels, hinges, support rod assemblies and fixed lock seats. The door panel is a thin plate structure, with an arc-shaped curling edge and a notch for avoiding handle 4.1a at the bottom. When the side door is closed, this curling edge is pressed against the longitudinal beam at the bottom of the box by the support rod body, and the two are kept in close contact, see Figure 7 , Figure 8As shown; at least two hinged hinges are arranged on the upper part of the side door, which rotate and provide fixing when the side door is opened, and the opening angle is generally 90° to 100°; the support rod assemblies of door 1 and door 3 are arranged oppositely, and one end close to the rod end lock 4.1b is the movable end of the support rod, and the other end rotates around the vertical center of the rotating pin 4.3. The support rod 4.1 and the double-headed connecting pin 4.2 coaxially pass through the lower opening of the rotating pin 4.3 and are connected to the fastening nut 4.4 as an integral component. When the handle 4.1a buckle is unlocked and the support rod is rotated 90°, the rod end lock 4.1b is unlocked, and the side door can be opened by lifting the support rod; the fixed card seat 4.5 is welded to the door panel to provide positioning for the rotating pin 4.3. Door 2 includes a door panel and a hinge. A notch is set at the symmetrical center of the lower edge of the door panel to avoid the fixed lock seat 5 matched with the rod end lock 4.1b of the door 1 and door 3 support rods. The fixed lock seat 5 is welded to the longitudinal beam of the box body. The side door unit can provide a fully open loading and unloading space for loading and unloading operations, effectively improving loading and unloading efficiency.

[0045] The support rod assembly of the present invention comprises a support rod 4.1, a double-headed connecting pin 4.2, a rotating pin 4.3, a fastening nut 4.4, a fixing base 4.5, and a rivet 4.6. Figure 6 As shown. At least one operating handle 4.1a is welded on the rod body of the support rod 4.1. The handle is engaged with the buckle 6 on the box frame. The locking claw of the lock buckle 4.1b at the end of the support rod cooperates with the fixed lock seat 5 limit platform in pairs. The two can be locked or opened by adjusting the rotation angle. A flat head joint with a hole is set at the other end of the support rod, which is embedded in the male and female fit of the middle slot of the first matching part of the double-headed connecting pin 4.2, and is pinned by a rivet 4.6. The support rod and the double-headed connecting pin can be rotated forward and backward within a range of 90° around the center of the rivet. The round pin surface at the other end of the double-headed connecting pin 4.2 is the second matching part, which passes through the lower round hole of the rotating pin 4.3 and is connected to the fastening nut 4.4 by the thread of the third matching part at the end. The rotating pin 4.3 includes a rotating pin body 4.3a, a stopper block 4.3b and a key pin 4.3c. The rotating pin body 4.3a is inserted from the bottom round hole of the fixed card seat 4.5, and is inserted into the stopper block 4.3b and is fastened by the key pin 4.3c as a whole. The cylindrical surface of the rotating pin body 4.3a is respectively positioned and rotated with the upper and lower round holes of the fixed card seat 4.5. A horizontal slot is set in the middle of the fixed card seat 4.5 for positioning and matching with the stopper block 4.3b. The upper and lower positioning holes are set in the vertical direction, and the inner side facade is welded to the door panel.

[0046] Alternatively, another solution for the rotating pin 4.3 is to connect the rotating pin 4.3 by spot welding of a screw and a nut to replace the functions of the limit block and the key pin.
