Description

The present invention relates to a supporting bracket according to claim 1 suitable for use in how you increase the cargo volume of the container ship.

  More particularly, the present invention relates to a cargo space of a container ship on which containers are loaded. In the prior art, a design having a cargo space that is used separately is known, in which a hatch cover is provided, a container is stored below the hatch cover, and the container is also loaded on the hatch. The container accommodated in the lower side of the hatch cover is supported so as not to move in the horizontal direction by a container supporting brace arranged in the cargo space of the ship. The container stacked on the hatch cover is fixed by a corner fixture and a bar with a rope of the container tightening device. However, this type of attachment with corner fittings and ropes is very unstable and the total weight of the stacked containers must be substantially limited. Therefore, the ship's cargo volume is less than the maximum available cargo space.

  In cargo spaces without hatches, it was possible to stack a very large number of containers with each other, as long as the strength of the lowest container allowed. The horizontal movement of the stacked containers is limited by the vertical container guide. However, the strength of conventional standard containers is so small that the total weight of the stacked container rows must still be greatly limited to prevent the bottom container from collapsing. Again, the ship's cargo capacity is not fully utilized.

  It is also possible to place the container from the container guide on a planar frame that is substantially the same size as the bottom of the container. The frame is moved by a lift. After loading, the frame is supported by the hull structure. This type of liftable frame takes up space, limiting the maximum cargo volume of the ship and slowing the loading and unloading work.

The purpose of the present invention, by the fact that it is possible to receive a larger vertical and horizontal forces, by providing a container supporting bracket suitable for use in a method for improving the cargo volume of container vessels It is.

The support brace method of the present invention comprises a container stacked in two or more divided stacks by mechanically operable support means fixedly or detachably attached to the hull structure. It is characterized in that the weight of the upper divided stacked portion is not transmitted to the lower divided stacked portion.

A preferred embodiment of this method is characterized in that the vertical load from the stacked containers is transferred to the hull structure via the container at the lowest position of each divided stack.

  The supporting arm according to the present invention is formed by a fixing housing member and an arm member rotatably connected to the fixing housing member, and the rotation of the rotatable arm member with respect to the stationary housing member is performed at two locations. In one of the restricted positions, the rotatable brace member bears the load applied thereto, and in the other restricted position, the rotatable brace member is rotated laterally to load the cargo. It is characterized by not obstructing wholesale.

  In another preferred embodiment of the support brace according to the present invention, the support brace receiving member is fixedly attached to the hull structure, and the support brace containing member and the rotatable brace member include The contours are defined to be substantially reciprocal with respect to overlapping surfaces, and the rotatable support brace moves within the receiving member to any position other than between the restricted positions of the rotatable brace member. It is characterized by not being.

  In another preferred embodiment of the support arm according to the present invention, the overlapping surface of the support arm housing member and the rotatable arm member has a curved outer shape.

  According to still another preferred aspect of the present invention, the support arm includes a connecting lever mechanism and a driving means for rotating the rotatable arm member.

The merit of the support method using the support brace of the present invention is that the cargo amount of the ship is greatly increased as compared with the conventional support structure. The support arm according to the present invention facilitates supporting large loads that are mobile with respect to the support arm assembly by using a small and uncomplicated member to receive the stress of the support force. It has the feature of being an efficient structure. Furthermore, the rotatable brace member can be removed, and can be inserted into a predetermined position only by a manual operation. The supporting arm structure of the present invention can be used very safely, and there is no need to fix the rotatable arm member at the lower position. Because of this effective design, the rotatable brace member is used for cargo that is lifted from the ship's cargo space, even if the brace member is unintentionally moved away from its lower position. Will not damage.

  In the following, the invention will be described in more detail with the aid of exemplary embodiments with reference to the accompanying drawings.

  FIG. 1 shows a cross section of a container ship. The ship has containers 1 stacked one by one and stored side by side adjacent to each other. The container guide frame extends vertically to the top of the stacked containers and supports the containers in the horizontal direction by container guides attached to the hull structure. In the vertical direction, the corner fittings are fixed to each other, and the containers are on top of each other.

  The vertical load generated by stacking containers is transmitted to the hull structure through the lowest container. If the load on the bottom container is estimated to be excessively high, intermediate support with the help of mechanically operable support means attached to the hull structure in a fixed or removable manner It can be split into two split stacks in the vertical direction at the desired point, supporting the split stacks above the points. As a result, the split piles below the intermediate support point are released from bearing the load of the split piles above. In this way, according to the present invention, with the help of the support means, a container piled up high can be prevented from being transferred to the divided stack section underneath the divided stack section of the container above the support means. By dividing into two or more divided stacked sections, the cargo amount of the container ship can be increased.

  The supporting arm 2 according to the present invention can be used as a mechanical supporting member (FIGS. 2 and 3). FIG. 2 shows a state in which the supporting arm is rotated to a position above it. In this way, the container 1 can be moved into and out of the cargo space without the need to remove the supporting arm. Allows loading and unloading. Conversely, the support brace shown in FIG. 3 is rotated to its container support position.

  In FIGS. 4-7, the structure of the preferred embodiment of the support brace 2 according to the invention is shown in great detail. Here, the supporting arm has two main parts, that is, a fixed housing member 2 ′ and a rotatable arm member 2 ″. Among these, the arm member is rotated and placed in an upper position. The arm member is not an obstacle to cargo handling such as cargo loading / unloading in the cargo space of the ship. Further, the supporting arm 2 is used for rotating the arm member 2 ″. You may have a connection lever mechanism and an actuator. The support arm 2 may be a removable assembly or may be permanently fixed to the hull structure of the ship. In the supporting brace assembly, the overlapping surfaces of the rotatable brace member 2 ″ and the fixed housing member 2 ′ are formed so as to substantially coincide. The rotatable brace member 2 in the fixed housing member. The movement of "" is restricted so as not to move in directions other than the vertical direction. FIG. 4 shows a state in which the supporting arm is rotated to an upper position, and the arm member does not hinder the loading / unloading operation of the load at this position. Conversely, FIG. 5 shows the supporting arm 2 in its use position, in which the arm bears the load applied thereto.

  When the rotatable arm member 2 "is in a lower position and is receiving a vertical load applied, the lower surface of the horizontally extending leg of the arm member is on the upper surface of the housing member 2 ', The curved leg of the rotatable brace member fits into a complementary shaped groove formed in the support brace receiving member, and is rotatable when the rotatable brace member receives a vertical force. The curved leg of the brace member does not move in the horizontal direction or twist about its longitudinal axis.

  It will be apparent to those skilled in the art that the present invention is not limited to the foregoing exemplary embodiments, but can be modified within the spirit of the present invention and the scope of the appended claims. For example, the shape of the supporting arm housing member 2 ′ and the rotatable arm member 2 ″ can be changed from the above-described one. Here, the supporting arm having a shape complementary to the rotatable arm member. The rotatable brace member 2 "is designed as a detachable element to be inserted and used in the supporting brace receiving member 2 'and is therefore shown in the drawings. The hinge is not an absolutely necessary element for practicing the present invention. Furthermore, the support brace of the present invention can be used to support, for example, other types of cargo or intermediate hatch covers in addition to containers.
