Description

[Detailed Description of the Invention] This invention relates to a cask holding device in a cask carrier.

A cask is extremely heavy, weighing over 100 tons, and contains used fuel, so
When transporting this by ship, it is necessary to securely hold it so that it does not move due to the shaking of the ship.

As a device to prevent the movement of cargo, a plurality of vertical and horizontal V-shaped protrusions are provided on the lower surface of the pallet, etc., and a plurality of vertical and horizontal V-shaped protrusions that fit with these protrusions are provided on the upper surface of the floor etc.
Types with shaped grooves are known. However, in this case, since the protrusions are provided on the lower surface of the pallet or the like, it is difficult to confirm that the protrusions are fitted into the grooves. Therefore, even if this is applied to a holding device for a cask, which is an extremely heavy object, the work of transporting the cask is dangerous and troublesome.

The purpose of this invention is to solve the above-mentioned problems, to be able to securely hold a cask placed on a cask holding stand and carried in by a mobile cart, to make the cask carrying work safe and easy, and to have a simple structure. The object of the present invention is to provide a cask holding device that is of excellent quality.

The cask holding device according to this invention is installed on the cask storage deck of a cask transport ship that carries out and carries in casks using a movable trolley that can raise and lower the cask holding platform to which the cask is fixed, except for both sides. A bogie running groove is provided on the cask fixed floor, a movable bogie rail is provided at the bottom of the bogie running groove, and substantially horizontal steps are provided on both sides of the upper part of the groove of the fixed floor to support both sides of the cask holding base. At the same time, a recess with an open top is provided at a predetermined position in the fixed bed outside the step so that the step protrudes outward. A protruding piece that enters and moves in and out is provided, and a vertical sensing rod that is movable up and down that projects downward from the cask holding table is placed in the cask holding table between the protruding pieces on both sides, and the sensing rod is biased downward. A spring is rotatably attached to the sensitive rod and the protruding piece at both ends, and when the sensitive rod moves upward, the protruding piece moves diagonally into the cask holding base, and the sensitive rod moves downward. The connecting rod is provided with a connecting rod that becomes nearly horizontal when the cask is moved, and causes the protruding piece to protrude from the side surface of the cask holding stand.

This invention will be explained below with reference to drawings showing embodiments.

1 and 2 show a part of a cask carrier, in which a cask fixed floor 1 is provided on a cask storage deck (not shown). Several movable carriage running grooves 2 are provided on the cask fixed floor 1, and a movable carriage rail 3 is provided at the bottom of each groove 2. In addition, a substantially horizontal step 4 is formed on both sides of the upper part of each groove 2, and a recess 5 with an open top is formed at a predetermined position of the fixed bed 1 outside the step 4 so that the step 4 protrudes outward. It is formed in the shape of

The cask C is fixed to the cask holding base 6,
It is moved by a moving cart 7. Hydraulic cylinders 8 are fixed upwardly to the movable truck 7 at its front and rear, and on both left and right sides, and the upper ends of piston rods 9 of the left and right cylinders 8 are connected to each other by a connecting member 10. Projecting pieces 12 to which connecting rods 11 are rotatably attached inside are provided on both the front and rear left and right sides of the cask holding stand 6, and the tips of the left and right connecting rods 11 are connected to the holding stand 6. It is rotatably attached to the upper end of a vertical sensing rod 13 that is attached to the center so that it can move up and down. The sensitive rod 13 is always urged downward by a coil spring 14 provided between the sensitive rod 13 and the holding table 6 so as to project downward from the holding table 6.

The cask storage deck may consist of an upper deck or may be located below the upper deck. In the former case, the mobile cart 7 is moved directly from the quay to the storage deck, and in the latter case,
After the mobile cart 7 is moved from the quay to the upper deck, it is lowered by an elevator or the like and moved to the storage deck.

In the above, the loading of the cask C onto the carrier ship is carried out as follows.

That is, first, on land, the cask C is fixed to the holding stand 6 in a sideways state as described above, and this holding stand 6 is placed on the trolley 7. Or trolley 7
The cask C is fixed on the holding stand 6 placed on the holding table 6 in a sideways state. Then, the rod 9 of the cylinder 8 of the truck 7 is advanced upward to lift the holding base 6 and the cask C, and the movable truck 7 is moved into the groove 2 by an appropriate means.
It is moved onto the inner rail 3 and stopped at a predetermined position so that the protruding piece 12 is directly above the recess 5. Note that when the holding stand 6 is placed on the cart 7, the connecting member 10 connecting the ends of the left and right rods 9 is attached to the holding stand 6.
in order to hit the sensitive rod 13 and push it upward,
The connecting rod 11 is tilted, and the left and right protruding pieces 12 are retracted into the holding table 6 (see FIG. 4). Therefore, there is no risk that the protruding piece 12 will hit people or things when the cart 7 moves, and it is safe. Further, it is not necessarily necessary to lift the holding table 6 above the cask fixed floor 1, and the holding table 6 can be moved while being lifted slightly above the step portion 4. In this way, the holding table 6 does not protrude significantly above the cask fixed bed 1, which is safer. When the moving carriage 7 is stopped at a predetermined position within the groove 2, the rod 9 of the cylinder 8 of the carriage 7 is retracted downward. As a result, the holding table 6 gradually descends,
Eventually, both sides of the lower surface thereof come into contact with the substantially horizontal step portion 4 and are supported. After the holding base 6 is supported by the stepped portion 4,
By further moving the rod 9 downward, the rod 9 is separated from the lower surface of the holding base 6, and the sensitive rod 13 is moved from the spring 1.
It moves downward by the force of 4. For this reason, connecting rod 1
1 becomes almost horizontal, the protruding pieces 12 protrude left and right from both sides of the holding base 6, and enter the recess 5 (the third
(see figure). Once the cask holding stand 6 is held on the fixed floor 1 in this manner, the cart 7 may be removed or may be fixed in place by applying a wheel stopper.

To unload the cask C fixed to the fixed bed 1, first the rod 9 of the cylinder 8 of the truck 7 is advanced upward. The rod 9 moves up and the connecting member 10
When the protruding piece 12 hits the lower surface of the holding table 6, the protruding piece 12 retreats into the holding table 6, and the rod 9 moves upward, so that the holding table 6 is lifted above the fixed bed 1. Then, the movable cart 7 with the holding platform 6 and the cask C lifted in this manner may be moved to the quay by appropriate means.

The casks C stacked on the fixed floor 1 are supported by the substantially horizontal steps 4 on both sides of the holding table 6, and the protruding pieces 1
2 has entered the recess 5, it is securely held without moving in either the front or back or left or right direction.

The number of protruding pieces 12 on the cask holding stand 6 is arbitrary, but it is sufficient that at least one piece is provided on each side of the holding stand 6. The configuration of the movable trolley 7 is not limited to that of the embodiment and can be modified as appropriate.

Since the cask holding device according to this invention has the above-described configuration, the holding table 6, that is, the cask C can be lifted from the fixed floor, or placed and fixed on the fixed floor 1 with both sides of the holding base 6 supported by the stepped portion 4 and the protruding piece 12 of the holding base 6 entering the recess 5. can. The movement of the holding base 6 in the width direction of the bogie running groove 2 is prevented by the step portion 4, and the holding base 6 in the length direction of the bogie running groove 2 is prevented from moving.
Since movement of the cask C is prevented by the recess 5 and the protruding piece 12 that has entered into the recess 5, the cask C is reliably held on the fixed bed 1. In addition, since the protruding piece 12 protruding from the side surface of the holding table 6 enters the recess 5 having an open top, it is easy to check and carry-in work of a cask, which is an extremely heavy object, can be carried out easily.
Furthermore, when lifting the holding table 6 by the moving cart, the sensitive rod 13 is pushed upward and the protruding pieces 1 on both sides
2 can be moved into and out of the holding table 6. Therefore, there is no risk that the protruding piece 12 will hit people or things when the cart moves, and it is safe. In addition, since the protruding piece 12 retracts into the holding base 6 during movement, it is not necessarily necessary to lift the holding base 6 above the cask fixed floor 1, and the holding stand 6 is raised slightly above the stepped portion 4. You can move with. In this way, the holding table 6 does not protrude significantly above the cask fixed bed 1, which is safer. Furthermore, when the holding base 6 is lifted up or lowered down by the movable cart, the lifting member pushes the sensitive bar 13 upward or moves away from the sensitive bar 13 downward, so that the protruding piece can be easily removed. 12 can be retracted or protruded. Therefore, no power is required to move the projecting piece 12 in and out, and its structure is extremely simple.
