Description

Technology Field

[0001] The present invention relates to a container for transporting coils, and more specifically, to a container for transporting coils that can transport coils in a securely bound and fixed state regardless of the type and specifications of the coils. Background Technology

[0002] Products that are very heavy and wound in a circular shape, such as iron coils, have very limited methods for transporting them for import and export. The methods mainly used are loading them in bulk onto bulk carriers dedicated to coils or loading them into containers and transporting them via regular shipping lines.

[0003] Shipping on dedicated coil bulk carriers is advantageous for transporting large quantities of a single product; however, its disadvantages include the fact that a certain amount of cargo loss occurs with every shipment due to the bulk loading method, and because it is an irregular service, it is difficult to operate under a Just-In-Time (JIT) production system, leading to inventory burdens.

[0004] The method of loading steel coils into containers and sending them via regular shipping lines has the advantage of ensuring on-time performance and enabling small-batch, multi-product shipments in accordance with production plans. However, since the coils are cylindrical, they may roll even if secured (shoring / lashing) inside the container, and because the load is large relative to the unit volume, the container cannot support the steel coils, resulting in frequent serious product damage. For this reason, many shipping companies classify coil products as undesirable cargo and manage them separately.

[0005] Therefore, a coil transport container has recently been proposed in which the bottom of the container is designed in a cradle shape to prevent rolling of the coil, prevent damage to the product and container, and ensure stable transportation.

[0006] For example, in Registered Patent No. 10-1473976 (December 11, 2014), a container was proposed that is attached to the longitudinal side wall of the container body and can support coil cargo in an unfolded state, and the support mechanism is configured to be folded and unfolded on the floor inside the container so as to enable the transportation of coils, etc.

[0007] In addition, Registered Patent No. 10-1659978 (September 20, 2016) also allows the support base to be rotated to form a horizontal plane or formed in a V-shape to support the coil, thereby enabling the selective or simultaneous loading of coil-type heavy objects and general cargo.

[0008] In addition, Registered Patent No. 20-0484170 (August 2, 2017) and Registered Utility Model No. 20-0485296 (December 12, 2017) have proposed a structure in which a V-shaped cargo support is provided inside a container to prevent the coil from moving while the coil product is loaded.

[0009] However, these methods can only temporarily fix and stabilize the coils, and there is a very high risk of product damage or safety accidents caused by the continuous movement of containers during maritime transport and unloading due to the fastenings coming undone.

[0010] In particular, coils vary greatly in the type of raw material, diameter, and width, and even if conventional containers are intended for coil transport, it is difficult to reliably transport all of the numerous types of coils. The problem to be solved

[0011] The present invention aims to solve the aforementioned problems by providing a coil transport container capable of simply loading and stably transporting coil cargo of various types and sizes.

[0012] In addition, the structure for supporting the coil is designed to be very simple, yet it is capable of maintaining a rigid fixed state even if the container moves or is subjected to external impact. means of solving the problem

[0013] The present invention, as a technical concept for achieving the above objective, relates to a coil transport container in which a V-shaped cargo support is formed to secure a coil inside the container, and a shackle for securing the coil is mounted on the cargo support. The cargo support comprises a support body formed along the longitudinal direction of the container and a guide detachably provided with the guide support body and configured to support the vertical cross-section of the coil when the coil cargo is loaded. The support body is configured with inclined surfaces such that both sides of the bottom surface face each other in a V-shape, and a plurality of fastening parts are formed on the first and second inclined surfaces formed along the longitudinal direction of the support body so as to face each other. The guide has fitting parts formed at both ends of a blocking bar corresponding to the fastening parts formed on the first and second inclined surfaces, and is fitted and fixed to the fastening part located closest to the coil among the plurality of fastening parts to support the vertical cross-section of the coil and restrict horizontal movement.

[0014] In addition, a socket tube is mounted vertically on the fastening part of the support body, and the guide is It is manufactured in a U-shape so that a guide is vertically inserted while the coil is placed on the support body to support the vertical cross-section of the coil, and multiple vertical walls are configured at the bottom of the support body to support the lower surface of the support body and to distribute the load generated by the weight of the coil to the side walls and floor of the container, thereby ensuring sufficient durability of the cargo support section that supports heavy coils. Effects of the invention

[0015] According to the coil transport container of the present invention, coil cargo of various types and sizes can be simply loaded regardless of the type and size of the coil, and the shoring operation, which is a securing operation to prevent the cargo from shaking during transport, is very simple and the working time can be significantly reduced.

[0016] In addition, the structure for supporting the coil is very simple, yet it can maintain a robust fixed state even if the container moves or is subjected to external impact. Furthermore, since the shoring is adjusted to correspond to the type and size of the coil, the coil weight does not act as a concentrated load on the container; instead, the load is distributed across the entire container through multiple socket pipes mounted on the support body, thereby preventing dangerous situations such as the container floor collapsing or the container being damaged during transport and enabling safe transportation.

Specific details for implementing the invention

[0018] The present invention will be described in detail below with reference to the attached drawings.

[0019] FIGS. 1 and 2 are drawings showing a state in which a coil is loaded into a coil transport container of the present invention, FIGS. 3 and 4 are drawings showing a structure for fixing the coil so that it does not move when loaded into the container, and FIGS. 5 is a drawing showing a state in which the coil is bound inside the container.

[0020] Referring to the drawings, the coil transport container of the present invention is structured such that a V-shaped cargo support (200) is formed inside the container (100) to accommodate a coil (C), and a shackle (300) for securing the coil (C) is mounted on the cargo support (200). The container (100) is formed as a cuboid box-shaped structure, and the cargo support (200) is configured to be mounted on the side wall and bottom inside the container to accommodate the lower part of the coil (C), which is a cylindrical cargo. When the coil (C) is secured on the cargo support (200), the upper part of the coil (C) is secured using the shackle (300) to prevent movement.

[0021] The above cargo support member (200) is a structure for stably supporting a coil (C) formed in a cylindrical structure, and a support body (220) is formed along the longitudinal direction of the container. A guide (240) for fixing the vertical cross-sections on both sides of the coil (C) while the coil (C) is seated on the support body (220) is configured to be detachable, so that after the coil (C) is seated on the support body (200), it can be fixed using the guide (240) so that no horizontal (front-back) movement occurs.

[0022] The above support body (220) is formed in a V-shape so that the outer diameter of the cylindrical coil (C) can be seated thereon. In order to efficiently support a heavy object, the central lower part of the support body (220) is formed as a horizontal bottom surface (222), and both sides are symmetrically formed as inclined surfaces (224) including first and second inclined surfaces (224a, 224b) so that they face each other in a V-shape. This double-folded structure of the bottom surface (222) and the inclined surfaces (224) further improves the durability of the metal plate, prevents bending, and maintains flatness.

[0023] At this time, shackles (300) for binding may be mounted at equal intervals along the longitudinal direction of the support body (200) on the upper side of the inclined surface (224) of the support body (220), and the upper end of the inclined surface (224) is mounted on the inner wall of the container (100) and is stably supported while being supported on the side wall of the inner space formed by a cuboid.

[0024] At this time, a bent portion (224c) may be further formed at the leading edge of the inclined surface (224) to be horizontal with the inner wall of the container (100), and through this bent portion (224c), the longitudinal durability of the support body (220) is further increased, and it becomes possible to mount it in a state of being more closely attached to the inner wall of the container through welding.

[0025] Additionally, a plurality of fastening holes (226) are formed facing each other on the first and second inclined surfaces (224a, 224b) formed along the longitudinal direction of the support body (220) so that the guide (240) can be detached. At this time, the inclined surface (224) is bent to fit the cylindrical shape of the coil (C) and has a bent angle that allows coils (C) of various sizes to be seated. When coils (C) of different diameters are seated on the support body (220), it is preferable for the angle of separation between the first and second inclined surfaces to be large in order to maintain the lower part of the coil (C) close to the bottom surface (222), but it is preferable for the angle of separation between the first and second inclined surfaces to be narrow in order to limit the movement of the coil (C) due to loads generated left and right and front and back caused by cornering and acceleration.

[0026] In addition, a socket tube (226a) is mounted on the back surface of the support body in which the fastening hole (226) is formed, so as to penetrate vertically, and the guide (240) has vertical portions (246) formed at both ends of the horizontal bar (242) corresponding to the fastening holes formed on the first and second inclined surfaces, so that the guide (240) is inserted into the fastening hole (226) that is close to the coil and fixed, thereby the horizontal bar (242) and the vertical bar (246) of the guide (240) support the vertical cross-section of the coil (C) and prevent horizontal (front and back) movement.

[0027] At this time, the same purpose can be achieved even if the guide (240) is fixed by inserting only the vertical bar (246) into each of the fastening holes (226).

[0028] To explain this in more detail, a socket tube (226a) is mounted vertically on the back side of the fastening hole (226) of the support body (220), and the guide (240) is formed with a horizontal bar (242) in a horizontal state and a vertical bar (246) with both ends bent downwards. By configuring it to be shaped like a guide so that the coil (C) is placed on the support body and the guide is inserted vertically from the top to the bottom to support the vertical cross-section of the coil (C), the vertical cross-sections on both sides of the coil (C) are stably supported simply by inserting the guide (240) while the coil (C) is placed on the support body (220).

[0029] At this time, the above fastening holes (226) can be arranged at equal intervals along the longitudinal direction of the support body (220) in plurality to prevent movement of coils (C) of various sizes (widths) and to fix them.

[0030] In addition, since the size of the coil (C) is of a wide variety of sizes, the spacing of the fastening holes (226) is equal, a gap may occur between the guide (240) and the vertical cross-section of the coil (C) when the guide (240) is inserted into the fastening holes (226). At this time, a sleeper can be inserted into the gap to support the coil (C) in a state where it is completely in close contact with the guide (240) so that it is firmly fixed. Furthermore, when the vertical bar (246) of the guide (240) is inserted vertically into the socket tube (226a) of the fastening holes (226), it can firmly fix both sides constituting the vertical cross-section of the coil (C) without moving laterally.

[0031] Then, with the lower part of the coil (C) seated on the support body (220) in this manner, it is fixed by the guide (240) to prevent horizontal movement, and in that state, as shown in FIG. 5, the upper part of the coil (C) is connected and fixed using the shackle (300) formed on the support body (220).

[0032] Therefore, after loading the coil (C) cargo into the container, the shoring operation to secure the coil (C) to the container is very simple regardless of the type and size of the coil (C), and the coil (C) is securely fixed, enabling safe transportation.

[0033] Meanwhile, as shown in FIG. 8, a plurality of vertical walls (260) may be mounted on the lower end of the support body (220) to support the lower surface of the support body (220) and to distribute the load caused by the weight of the coil (C) to the side walls and floor of the container. The vertical walls (260) may be configured such that a plurality of vertical walls (260) are arranged at equal intervals along the longitudinal direction of the support body (220) to distribute the load.

[0034] Therefore, even if the container moves or an external impact occurs while the coil (C) is loaded into the container, the weight of the coil (C) does not act as a concentrated load on the container but rather distributes the load across the entire container, thereby preventing partial damage or bursting, and preventing dangerous situations such as the container floor collapsing or the container being damaged during cargo transport, allowing for safe transport.

[0035] At this time, the vertical wall (260) mounted on the bottom of the support body (220) is configured with an arched lower section as shown in FIG. 9, which further improves the durability of the central part of the cargo support section (200) where the center of gravity of the coil (C) is concentrated, while also distributing the load to the lower side corner of the container.

[0036] And if a support bar (262) is installed on the lower side, which is formed with an arched cross-section like this, with a width relatively wider than the thickness of the upright wall (260), the load transmitted to the upright wall (260) can be distributed more efficiently.

[0037] At this time, the fastening holes (226) are formed at equal intervals, and a socket pipe (226a) is mounted on the back side of the support body where the fastening holes (226) are formed so as to communicate with the fastening holes, thereby allowing the load to be further distributed to the entire container by means of a plurality of socket pipes (226a) mounted on the support body. At this time, the vertical wall (260) can be configured to be placed between each socket pipe (226a) so that the load is distributed in a double manner.

[0038] In addition, a plate (227) may be attached to the fastening hole (226) to prevent deformation of the fastening hole (226) or the support body (220) and to provide a structure that is reinforced while the vertical bar of the guide (240) is inserted into the fastening hole (226).

[0039] At this time, the plate (227) can be firmly maintained in an upright state with the guide (240) inserted into the fastening hole (226) by welding it along the inclined surface on the top of the fastening hole (226) where the socket tube (226a) of the fastening hole (226) is mounted, as shown in FIG. 10.

[0040] Additionally, as shown in FIGS. 11 and 12, the plate (227) can be mounted on the vertical bar (246) of the guide (240) to limit the depth to which the vertical bar (246) of the guide (240) is inserted into the fastening hole (226), and at the same time, the plate (227a) can prevent lateral movement of the guide (240).

[0041] At this time, it is preferable to mount the plate (227a) to the vertical bar (246) of the guide (240) by welding. The plate (227a) is mounted to the vertical bar of the guide (240) at an angle corresponding to the inclination angle of the inclined surface (224) of the support body (220), and is inserted and fixed by engaging with the fastening hole (226). At this time, when welding the plate (227a) to the vertical bar (246), the plate (227a) is formed to wrap around the perimeter of the vertical bar (246), and one side is cut to wrap in a 'C' shape. This ensures that the plate (227a) does not protrude laterally in the part in contact with the coil (C), and the coil (C) is seated in a flat structure without shaking. The plate is formed to protrude only to the outside of the vertical bar (246) to reinforce the fastening hole (226), and the vertical bar (246) is inserted into the fastening hole (226). It becomes possible to maintain a tight assembly state.

[0042] Meanwhile, in order to support the lower surface of the coil (C) while the coil (C) is seated on the inclined surface (224) of the above-mentioned support body (220), a support member (280) may be formed on the bottom surface (222).

[0043] The above support member (280) can increase the surface area on which the coil (C) is supported or provide a cushioning function, thereby allowing the loading state of the coil (C) to be supported more stably.

[0044] That is, as shown in FIGS. 13 and 14, the structure of the support member (280) is composed of a plurality of separated pads (282) that support the lower part of the coil (C), and when the pads (282) are connected by an axis (284), the pads (282) support the lower part of the coil (C) in a state of being connected to an inclined surface along the outer diameter of the coil (C), and are structured to be variable in correspondence with the outer diameter even when the outer diameter of the coil (C) changes, thereby increasing the contact area where the coil (C) is supported.

[0045] Additionally, as shown in FIG. 15, each pad (282) may have a non-slip member added to provide cushioning and implement a non-slip function while the coil (C) is seated on the top of the pad (282), and an elastic member (286) may be installed on the bottom of the pad (282) to provide a cushioning function and closely support the bottom while elastic action is performed when the pad (282) supports the bottom of the coil (C).

[0046] Meanwhile, as illustrated in FIG. 16, a socket tube (226a) mounted in communication with a fastening hole (226) provided in the support body (220) may be further provided with a height adjustment means (228) for setting the insertion depth of the vertical bar (246) of the guide (240). When assembling the guide (240) into the fastening hole (226), the adjustment means (228) is selectively inserted into the adjustment hole (228a) to a depth appropriate to the outer diameter of the coil (C), thereby adjusting the insertion depth of the vertical tube (246) and stably adjusting the position of the horizontal bar (242) to support the coil in a way that restricts its horizontal (front-back) movement.

[0047] Typically, the wound coil (C) is configured with an outer diameter of very different sizes depending on the number of turns. In order to efficiently block lateral flow of the coil (C), it is desirable to have a wide contact area with the vertical cross-section of the coil (C), and it is also desirable to position the horizontal bar (242) of the guide (240) at a height close to the center of the vertical cross-section of the coil (C). As described above, the height of the horizontal bar (242) of the guide (240) can be freely set using a height adjustment means (228) to ensure stable cargo transport.

[0048] Meanwhile, the above container (100) is configured with an open top structure so that the coil can be loaded and unloaded using a crane or the like, thereby allowing the coil to be placed in the correct position on the top of the cargo support (200).

[0049] At this time, a roof (120) is mounted on the upper part of the container (100) so that the opening and closing of the container can be controlled, and the roof (120) can be mounted in a rail structure so that the opening and closing operation is performed in a sliding manner.

[0050] That is, as illustrated in FIG. 17, the roof (120) mounted on the container (100) is configured with a rail (122) on the upper side wall of the container, and a slider (124) is mounted on the rail (122) to enable reciprocating movement, and a bracket (126) for mounting a roof material (not shown) is mounted on the slider (124) so ​​that the roof can be opened or closed by opening or closing the roof material that is stretched across the bracket (126).

[0051] At this time, the slider (124) equipped with the bracket (126) may be configured in multiple units to move left and right on the rail (122), thereby preventing sagging when the loop material (not shown) is made of a fabric material such as fiber or a flexible synthetic resin, and allowing the opening width to be set in various ways as needed, while ensuring stable opening and closing operation of the loop.
