Description

Underframe of container, cargo loading platform and container
Technical Field
The invention relates to the technical field of containers.
Background
A pallet container as one type of container generally comprises a cargo-carrying chassis, and of course, some pallet containers further comprise end frames provided at both ends of the chassis, and some pallet containers provided with end frames may be foldable. The rack type container is flexible to use, can load ultra-wide cargoes as the rack type container has no side wall and top plate, is convenient for loading and unloading cargoes, has high operation efficiency and wide application, and can conveniently transport ultra-long cargoes without an end rack. The rack box of the foldable end frame can be connected with a plurality of folded boxes to form a transportation module when the empty boxes are returned, so that the transportation cost is greatly reduced.
The characteristics of the rack box, which are convenient to assemble and disassemble, make the rack box be used for loading ultra-wide, ultra-long and special-shaped goods. The goods are required to be effectively fixed with the box body of the rack box during transportation, and unlike a conventional container, the rack box is not provided with a top plate and side edges, and the goods can not be fixed in an auxiliary manner through the top plate or the side plates, binding hooks, binding rings and the like on the top plate or the side plates. There are also congenital weaknesses in the transportation of such goods, so that the current solutions are specifically tailored to the shape, characteristics, etc. of the goods.
For example, modules for transporting cylindrical goods are often provided with grooves in the upper surface of the platform of the gantry, so that the grooves can be used for securing the goods. The rack container for transporting plate-shaped goods (such as stone slabs and the like which need to be placed on side) is provided with a foldable goods fixing frame on the upper plane. Special boxes such as these can also solve the problem of transportation and fixation of the corresponding goods. However, this method of customization has many limitations: firstly, special cases are needed, and the universality is completely avoided; and secondly, the manufacturing cost of the customized case is high, and when specific goods are not required to be transported, the customized case cannot be loaded with common goods, or the customized case is used for loading the common goods, so that the customized case is uneconomical.
Accordingly, there is a need to provide a chassis, cargo loading platform and container for a container that at least partially addresses the above-described problems.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present invention. It will be apparent that embodiments of the invention may be practiced without limitation to the specific details that are set forth by those skilled in the art.
As shown in fig. 1, four corners of the bottom frames 110 of the container are provided with coupling pieces 111 and corner pieces 112, and the coupling pieces 111 are provided above the corner pieces 112, which can be used for coupling between two bottom frames 110. The container of the invention can be a rack type container or other types of containers. The undercarriage 110 is provided with four inwardly recessed interface portions 120 for limiting movement of the grooved cargo loading platform 180 in a longitudinal direction along the undercarriage 110. The number of the interface parts 120 is not limited to four, and may be more than four. The cargo loading platform 180 includes a platform body 183 and bosses 181 provided at four bottom corners of the platform body, the bosses 181 protrude from the platform body 183, when loading cargo, the cargo is loaded on the container through the cargo loading platform 180, the four bosses 181 of the cargo loading platform 180 respectively fall into the four interface parts 120, and the interface parts 120 further include locking members for fixing the bosses 181 in the interface parts 120. The boss 181 may include a bottom corner member, and of course, may include other parts protruding from the lower surface of the cargo loading platform, and the number of the bosses 181 is not limited to four, and corresponds to the number of the interface portions 120 provided on the bottom chassis 110, so that each interface portion 120 accommodates one boss 181. The locking member includes a twist lock attachment hole for attachment to a twist lock, the twist lock attachment hole being disposed within the interface portion 120. When the twist lock is needed to be used, the bottom corner piece on the goods loading platform can be additionally locked with the twist lock connecting hole of the interface part. Of course, the locking member may also be a twist lock structure, which is arranged in the interface portion.
Specifically, as shown in fig. 2, the interface 120 includes a recess 130, and the recess 130 is recessed downward from the upper surface 113 of the chassis 110. The locking member may be a lifting locking member or a reversible locking member. Fig. 2 shows the flip-type locking member 140 in an open position that does not protrude from the upper surface 113 of the chassis 110. The same is true for a lifting type locking member which is not shown, wherein the lifting type locking member comprises a lock head and a lock seat, and the lock head and the lock seat are both in a descending position and do not protrude from the upper surface of the underframe when the lifting type locking member is in a to-be-used state; the lock head and the lock seat are lifted upwards under the action of external force and protrude out of the upper surface of the underframe; when the lifting locking member is in the raised position, the locking head is rotated 90 degrees so that the long side of the locking head is perpendicular to the long side of the lock base, and the corner fitting of the cargo loading platform 180 can be connected with the locking head, thereby connecting the cargo loading platform 180 with the chassis.
In an alternative embodiment, the cargo loading platform 180 with recesses, schematically shown in fig. 3, is a holder for loading cylindrical shaped cargo 171. In another alternative embodiment, as shown in fig. 6, the cargo loading platform 182 may be a collapsible cargo holder such that a plate-like cargo 172, such as slate or glass, may be placed sideways on the cargo loading platform 182. Of course, if the liquid is transported, the cargo loading platform is also of tank construction. If overweight goods are transported, then the goods loading platform can be made stronger at this moment, makes it can bear the weight of goods with the chassis jointly, makes up the problem that this bench formula collection dress intensity or rigidity are not enough.
As shown in fig. 4 and 5, the cargo loading platform 180 is provided with a boss 181 protruding outward, and the boss 181 is provided at a position corresponding to the interface part 120 so that the boss 181 is connected with the interface part 120, so that the bottom chassis 110 is connected with the cargo loading platform 180. The four corners of the chassis 110 are provided with the interface portions 120, and correspondingly, the four corners of the cargo loading platform 180 are correspondingly provided with the bosses 181.
The interface 120 and the boss 181 are shaped and sized to mate in the longitudinal direction such that when the boss 181 is inserted into the interface 120, the interface 120 restricts movement of the boss 181 in the longitudinal direction along the chassis 110. Further, the interface portion 120 and the boss 181 are cooperatively shaped and sized in the lateral direction such that when the boss 181 is embedded in the interface portion 120, the interface portion 120 restricts movement of the bottom corner member in the lateral direction along the chassis 110. The longitudinal direction of the chassis 110 is the transport direction of the container, and the transverse direction of the chassis 110 is the direction perpendicular to the longitudinal direction.
The depth of the interface portion 120 may be 30mm-118mm, and the boss 181 may be moved 3mm-20mm in the longitudinal direction of the base frame 110 within the interface portion 120. When the depth of the interface part 120 is 30mm, the contact area between the boss 181 and the interface part 120 is 2.7 times that of the conventional twist lock connection, that is, the longitudinal bolting capability is stronger, and the requirement of railway transportation can be met. The height of the interface 120 is 118mm, and the top surface of the boss 181 is arranged at the bottom of the cargo loading platform, so that the contact area is larger, the capability of longitudinal bolting is stronger, and meanwhile, the connection structure of the cargo loading platform is simpler because the whole boss 181 is arranged at the bottom of the cargo loading platform. In addition, the height is preferably 50mm in consideration of the fact that the flip type twist lock has a twist lock arm. The boss 181 can move 3-20mm in the interface portion 120 along the longitudinal direction of the chassis 110, mainly considering that the twist lock core and the twist lock hole can slide relatively, the minimum sliding distance is 3mm, and if the installation gap between the boss 181 and the interface portion 120 is small, the use is inconvenient; the maximum sliding amount allowable by the ISO twist lock in the ISO corner fitting hole is 20mm, the installation clearance between the boss 181 and the interface part 120 is large, the use is convenient, the movement amount between the boss 181 and the interface part 120 is preferably 15mm in consideration of the size difference of part manufacture, the installation clearance can be ensured, and the use is convenient. Among these, the longitudinal movement amount is mainly considered: when the loading platform is used, under the acceleration action during transportation, the boss 181 is firstly contacted with the side surface of the concave part 130 of the interface part 120, so that the acting force of longitudinal bolting firstly acts on the contact surface of the boss 181 and the concave part 130, but not directly acts on the torsion lock, and the longitudinal bolting capability is stronger.
Specifically, as shown in fig. 4, the cargo loading platform 180 has a boss 181 protruding downward, and the boss 181 may be a hanging member or may be used for hanging between two bottom frames. The connector is a corner fitting, and can also be other connector with similar functions. Fig. 4 shows the flip-type locking member 140 in a locked position protruding from the upper surface 113 of the chassis 110, with the recess 130 of the interface portion 120 exposed. The cargo loading platform 180 is placed on the underframe 110 of the pallet-type container, after aligning the coupling piece 111 on the cargo loading platform 180 with the interface portion 120 on the underframe 110, the flip-type locking member 140 is aligned with a connection hole (not shown) of the boss 181 on the cargo loading platform 180, the boss 181 is integrally embedded in the recess 130, and the size of the boss 181 can be matched with the size of the recess 130. The recess 130 restricts movement of the boss 181 in the longitudinal direction of the chassis 110, and the recess 130 restricts movement of the boss 181 in the lateral direction of the chassis 110.
Specifically, as shown in fig. 7 to 9, the interface portion 120 includes a connection plate 150, a recess 130, a flip lock member 140, and an operation hole 160. The connection plate 150 is connected with the wall plate 121 of the interface portion 120 to partition the interface portion 120 into the cavity 122. The flip lock member 140 is flip-ably connected to the connection plate 150 through a flip shaft 152. The flip type locking member 140 includes a lock base 141, a rotation shaft 142, a locking head 143, and a boss pin 144. The rotary shaft 142 has a first end provided with a locking head 143 and a second end provided with a protruding pin 144. The lock base 141 is connected to the tilting shaft 152, and the rotation shaft 142 passes through the lock base 141 along the axial center of the lock base 141. As shown in fig. 8, the length direction of the locking head 143 and the protruding pin 144 is identical to the length direction of the lock housing 141 such that the reversible locking member 140 is in the open position. As shown in fig. 9, the length direction of the locking head 143 and the protruding pin 144 is perpendicular to the length direction of the lock housing 141 such that the reversible locking member 140 is in the locked position.
When the reversible locking member 140 is in the open position, the reversible locking member 140 is received in the recess 130. The connection plate 150 is provided with a through hole 151, and when the reversible locking member 140 is turned from the open position to the locked position, the lock base 141 is turned around the turning shaft 152 such that the protruding pin 144 is rotatably received in the cavity 122 through the through hole 151. Of course, when the reversible locking member 140 is turned from the locked position to the unlocked position, the lock housing 141 is turned around the turning shaft 152 so that the lock housing 141 is rotatably accommodated in the recess 130.
An operation hole 160 is provided on the wall plate 121 of the mouthpiece 120 for communicating the cavity 122 with the outside of the mouthpiece 120. As shown in fig. 10, when the reversible locking member 140 is in the locked position, the cam 144 is rotated to rotate the locking head 143 about the rotational axis 142. The operator's hand or tool rotates the boss 144 through the operation hole 160, thereby rotating the locking head 143, so that the locking head 143 locks the boss 181 of the cargo loading platform 180, thereby connecting the bottom chassis 110 and the cargo loading platform 180 together. The link 111 restricts displacement of the cargo loading platform 180 in the vertical direction.
If the cargo loading platform and the cargo arranged on the cargo loading platform are heavy, vehicles such as trains or automobiles are adopted in the transportation process, the trains or automobiles are braked or started, and the acting force applied to the underframe in the horizontal direction is overlarge. If the limit is performed only by the locking member, the locking member or the hanging piece is easily damaged. According to the invention, the cargo loading platform is provided with the bottom corner fitting, the bottom frame is provided with the interface part, the bottom corner fitting is embedded into the interface part with matched shape and size, and the interface part plays a role in limiting movement of the whole bottom corner fitting along the longitudinal direction of the bottom frame, so that the horizontal limit of the cargo loading platform is safely and reliably realized. The locking member in the interface portion will not protrude above the upper plane of the undercarriage so that the undercarriage will not be obstructed at all when normal cargo is transported directly without loading the cargo loading platform.
