The present invention relates to a container for bulk cargo transportation. Since 70% of the earth's surface is at sea, ocean transport plays an important role in world trade. Container shipments instead of conventional transportation devices are being used innovatively in many other areas besides transporting bulk cargoes such as coal, grain, streams and other necessities.

To date, the United States is the world's largest grain exporter, selling enormous quantities of crops to Far Eastern countries such as China, Japan, South Korea, the Soviet Union, and China. Exports are increasing each year and a small number of grains are very limited. Although they are transported in bulk containers, most exports are transported to destinations by conventional bulk carriers.

Transporting oxidized cargo in conventional dry cargo containers is not suitable, resulting in a waste of energy since a huge number of such containers do not carry cargo and must be returned to the port from the Far East where export cargo is waiting for shipment. It is known worldwide that cargo ships are transported on a regular basis and not on a regular basis. The distribution relationship of cargo is always influenced by the availability of cargo ships, which greatly affects the economic effect of storage and distribution of goods.

Using the present invention for the use of ordinary empty dry cargo containers, which have to go back to various ports, it is possible to make minor changes when the containers are manufactured to reduce the cost of the shipping operator. Since the new container is ordered when the old container reaches the end of its life, the present invention can be applied when there is an order for a new container.

The present invention is an improvement of the structure of a conventional dry cargo container to bulk transport when sailing to the Far East where exports are exported from the United States and bulk cargoes such as grains are imported. This is a very practical use of the container being used now. It is a main object of the present invention to provide a container in which a door structure is formed at the top and bottom center of the container. Stacking several containers on the ship while the door is open creates a through hole. When the door of the container is closed, the container can be used for the general purpose of the dry cargo container.

Other objects, features and functions of the present invention will be described in detail with reference to the accompanying drawings. First, a description will be given with reference to FIGS. 1 to 5. There is a sliding door (1) at the top of the container (C) and a bottom door (2) at the bottom. These two doors provide adequate space for the container's auxiliary pipes to operate without compromising the structural strength of the original container.

The sliding door 1 is welded to the top of the container c and consists of two main parts: the joint seat 11 and the sliding window 12. The periphery of the joint sheet 11 has a box shape (C-shape) with one side open, and guide rails 110 are formed on both sides of the joint sheet 11. The bottom face 111 of the joint seat 11 is open and at its top there is an opening 112 and a flat face 113 (adjacent to the body of the joint sheet) situated adjacent thereto.

At the proper position of the surface and bottom portion of the U-shaped frames 114 and 115 of the joint seat 11 there are several thru holes 116 for fixing the bolts 117. There is a seat for securing the volk 118 at a suitable position in the bottom portion of the frame 114 (shown in FIG. 3). The sliding window 12 may slide into the guide rail 110 and may be firmly fixed to the joint seat 11. The sliding window 12 is attached with a rubber cushion 121 to be waterproof when closed.

The bolt 117 is used to press the rubber cushion 121 or less, and the bolt 118 is used to firmly secure the sliding window 12. The bottom portion 2 has a base 21, a door 22 hinged at one side of the base 21 to form a through hole 210 (FIG. 5), and a check edge with a rubber cushion 212. It consists of 211.

The door 22 has an edge that presses the rubber cushion 212 when the door is closed, and is designed to be firmly fixed to the frame of the base 21. The structure of the door 22 is reinforced with a support plate 222 which is the same as the bottom structure of the actual container. In front of the door 22 is a concave space 223 in which the lock 224 is located. When the sliding door 1 is closed, the sliding window 12 is pulled completely to one side so as to cover the opening 112 at the top of the joint seat 11 (see FIG. 3).

When the screw bolt 117 is firmly fixed to the pad pad 119 at the bottom, the sliding window 12 is firmly fixed to the rubber cushion 121 along the seat frames 114 and 115 while forming a gas tight seal. do. The bottom door 2 is tightly closed to the base 21 by the lock 224 when the door 22 is closed to the base 21.

In this way, a container with sliding doors and bottom doors can be used as a normal dry cargo container. The operation method when loading oxidized cargo is as follows.

1. Loosen the bolt (117).

2. Slide the sliding window (12) along the guide rail (110) to the other end under the flat surface (113).

3. Secure bolt 118 properly to prevent sliding window 12 from sliding backward.

4. Release the lock 224 of the bottom door 2 and then lift the door 22 so that it rests on the bottom of the container so that the through hole 210 can be opened on the opposite side of the opening 112. .

When loading cargo on board, instead of using conventional belt conveyors, the loading of such cargo, such as grains, is carried on the carriers using an auxiliary device which draws the cargo into the hold of the boat.

Auxiliary devices also draw into the silo to draw or store cargo from the window to bag it. The device consists of a pipe end where the cargo is sucked in and an outlet through which the cargo flows out.

The present invention utilizes an auxiliary distribution pipe connected with the main suction pipe. Although it is necessary to explain in detail the fitting apparatus of this auxiliary pipe, it is abbreviate | omitted since it is not included in the meaning of this invention. Hereinafter, a description will be given with reference to FIGS. 7 and 8. The auxiliary distribution pipe arrangement is made up of a series of multi-section pipes 5, between each connecting pipe 5 there is a valve 6 at a suitable position to regulate the flow of compressed air into each section. Along the pipe 5 of each section there is a connecting joint 512 and a short protruding pipe 51 adapted to connect to the pipe device for suction / discharge. Each protruding pipe 51 is equipped with a valve 511 for regulating the flow of each section.

The end of the suction / discharge pipe arrangement is flexible to extend in length (vertically) and in length (horizontally). The pipe 5 has a ring which is used by the crane at the dock to lift the pipe to the appropriate place at the top of the container.

After the pipe 5 is connected, one end thereof is tightly sealed and the other end is opened to connect the main pipe 4 with the joint 3 to the end of the open side. Connected to the joint 71 at the joint 512 of the protruding pipe 51 The vertical connecting pipe 7 of the intake / discharge pipe arrangement can extend to some depth for proper operation. The photoelectric tube 9 is attached to the joint 72 at the top of the elbow pipe 8 at the lower end of the pipe 7. The phototube 9 is visually shown in the CRT in the throttle plate which is connected to a monitor device for monitoring the internal situation of the container and which the operator can properly handle the device for the desired purpose.

The monitor also relays the situation of the pipe 101. The end of the horizontal tube 10 is attached with a rotary wheel 20 that is moved by an air motor to expand or contract the tube 10 to the desired position. Hereinafter, the operation of the auxiliary distribution pipe device will be described.

The pipe arrangement described above is equipped with a suction / discharge device which can be expanded / contracted by two sets for suction / discharge of cargo during operation. This pipe arrangement is connected to the vertical pipe 7 at the protruding pipe 51 of the pipe 5 and to the main hose (pipe) 4 at the joint 3. The valve 6 of the pipe arrangement in use is opened to allow compressed air to flow in the section of the pipe 5 in use and the valve of the other section is closed.

The suction / discharge pipe device, which can be expanded / contracted vertically, enters the container in which the cargo suction / discharge takes place with a connecting pipe 7 adjusted to the desired length.

This adjustment is made by the pulley 73 which is lifted by a crane under the vertical connecting pipe 7. The horizontally expandable end tube 10 can be extended to a desired position with the aid of an eye visible display on the throttle. The tube 10 is actuated by a rotary wheel 20, in which the wheel moves slowly toward the cargo by the wheel propulsion action, while the suction pipe 101 absorbs the grain into the pipe system. Expansion and contraction of the tube 10 may be accomplished by rotating wheels.

The vertical connection pipe 7 is connected to the elbow pipe 8 at a joint 72 which can rotate in the desired direction. Thus, together with the elbow pipe 8 and the photoelectric tube 9, the tube 10 can rotate 360 degrees about the axis of the vertical connection pipe (7). Thanks to the free movement of the vertically connected pipe 7 and the horizontal tube 10, the suction and pouring of the cargo can be done effectively in the corner of the container. When one of the stacked containers is fully loaded or completely empty, the vertical connecting pipe 7 is connected to the next container in the stacked containers for pouring or suctioning action.

When loading, pouring is done first at the bottom of the container and when the bottom container is full it moves up towards the next. At the time of release, suction is done downward from the top of the container towards the bottom layer. The monitor device helps a lot in controlling the intake / discharge. Next, the complete sealing of the stacked containers will be described.

The present invention also relates to the complete sealing of multiple stacked containers, one by one, to protect the load on stacked containers during long-term transportation. Preventing the sliding out is first done by the corner fitting of each container. The main action of the corner fitting is to maintain the position to lift the container during normal operation, and the other action is to prevent it from sliding horizontally by preventing access to the other container when stacked one by one.

When containers are stacked, an ordinary container has a few inches of free space between the top of one container and the bottom of the container directly above it, so the present invention provides a height of protrusion of the door to be additionally installed on the top and bottom of the improved container. Also considered. The door is designed to be completely sealed when two containers are stacked on top of each other.

Additional fittings or cushions may be installed to ensure a complete seal to ensure the cargo is safely protected if extra space is created due to the wear of the container.

According to the load standard, a 40ft container can support a 35 ton load or 50 m ³ (weight distribution is 1.4 CBM / IMR); under a stationary torso, the load weight is about 75 tons.

The present invention relates to the load of a cargo under a stationary state, and there is no problem in supporting the load even if the strength to be constructed is weak.
