Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an onboard loading device for bulk cement carriers.

[0002]

2. Description of the Related Art The loading device for bulk cement carriers is
A transport path such as an air slide is provided from the central distributor that receives bulk cement to the bow and stern in the starboard and starboard directions. Bulk cement supplied from an external loading device was appropriately distributed and loaded in these transport paths. Each hold in the ship is No. 1 from the bow toward the stern. 1 to N
o. It is divided into 4 chambers of 4, and multiple operators are constantly monitoring it so that imbalance between the port and starboard does not occur, and the opening of the adjusting gate of the transport path is manually adjusted appropriately to prevent imbalance. It was

[0003]

As described above, even under constant operator monitoring conditions, external causes such as the hull, waves and winds during loading, unbalance of the dust collection line, left / right error in the installation state of the loading device, etc. As a result, there were problems such as uneven loading on each hold and imbalance between the port and the starboard in the hold, and it took a great deal of time to correct them.

The present invention aims to remedy such drawbacks.

[0005]

According to the present invention, an inclinometer is provided on a ship in an inboard device of a bulk cement carrier having carrier paths extending from the central distributor to four starboard and stern port starboard directions. An adjustment gate capable of adjusting the opening to the directional conveyance path is provided, and an adjuster for adjusting the opening of the adjustment gate is provided so that the inclination becomes zero in response to a signal from the inclinometer. It is a loading device for bulk cement carriers.

[0006]

In the present invention, the unbalance of the load of the bulk cement carrier is judged by the inclinometer of the ship, and the adjuster for automatically adjusting the opening degree of the adjusting gates in the four directions is provided so that the inclination becomes zero. Therefore, the load can be automatically equalized. By using an inclinometer having an accuracy higher than 0.1 degrees as the inclinometer, practically sufficient uniform loading can be performed.

1 is a plan view of an onboard loading apparatus according to an embodiment. In the figure, the alternate long and short dash line indicates the bulk cement carrier No. 1 to
No. 4 hold is shown, and a loading device including a main loading air slide 1, a distribution tank 1b, four adjusting gates 2, and a transport air slide 3 is mounted.

Main loading air slides 1 are provided on the left and right sides so that loading can be done from the port side or the starboard side, and each has two loading ports 1a. Air supply to the main loading air slide 1 is manual. This main loading air slide 1
Guides loose cement to the central distribution tank 1b. The distribution tank 1b is provided with a transporting air slide 3 for feeding in four directions, and the entrance thereof is provided with a cut gate horizontal type adjusting gate 2 as shown in FIG. The adjusting gate 2 is provided with a fan-shaped cut gate 2a, and adjusts the carrying amount by limiting the height of the cement carried by the air slide from the right side in FIG. The opening of the adjusting gate 2 is adjusted by driving the motor to a fully closed position indicated by a gate position 2a, a fully opened position indicated by a gate position 2b in the drawing, or an intermediate position therebetween. The relationship between the gauge opening (% step) of the adjusting gate 2 and the transport amount, that is, the cross-sectional height of the passing cement amount is shown in FIG.

The distribution air slide 3 is branched from the distribution tank 1b in four directions. The branching air slides 3 are each provided with an intermediate discharge valve 4 and a shut gate 5, and an open air slide 6 is provided at the tip of the branching air slides 3 so that the cement load is dispersed and loaded, and the distribution of the loaded load is averaged. Has become. Flowing air from an air slide fan is supplied to these air slides 1, 3, and 6. An automatic valve is provided in the air path, the path is checked by a limit switch, and the air cylinder is operated.

An inclinometer with an accuracy within 1/10 degree is provided on the ship. When the inclinometer is tilted at 5/10 degree or more, the drive motor cylinder of the adjusting gate 2 is automatically operated to operate the inclinometer. An automatic adjuster was installed to correct the inclination to zero.

[0011]

EFFECTS OF THE INVENTION According to the present invention, since the deviation of the loading amount of loose cement does not occur, the deviation adjustment work is unnecessary, the loading efficiency is improved, the ship stagnation time is shortened, and the securing of skilled personnel is eased. And other effects.
