Description

Reversing device for irregular block and method for installing irregular block

The present invention relates to a device that reverses a deformed block according to the installation posture when installing or moving a deformed block used for wave suppression, and more specifically, a deformed block using a clamp device. The present invention relates to a reversing device that changes the orientation of the odd-shaped block with respect to the clamping device when gripping.

Conventionally, for the revetment and wave-dissipation, blocks such as rectangular parallelepipeds and cubes as well as deformed concrete blocks such as tetrapod blocks called tetrapod trade names have been used for structures such as breakwaters. These deformed blocks are usually stacked sequentially on the seabed or mound, or appropriately arranged on the front of a breakwater or revetment to constitute a wave breakwater revetment structure.

By the way, most of the deformed blocks are not built up randomly, but in order to prevent the deformed blocks from collapsing due to waves to hit, it is necessary to install so that the legs of the adjacent deformed blocks are entangled with each other It has been demanded. Then, when stacking the odd-shaped blocks, there are postures of the odd-shaped blocks that are entangled with each other, that is, the arranged postures, and the blocks are suspended and arranged at the installation position so as to be in these arranged postures.

This arrangement posture has various postures depending on the shape of the deformed block. For example, in a three-dimensional block with four legs extending radially called a tetrapod product name, the legs extending vertically are positioned on the upper side. The three orientations are adopted: the normal position, the inverted position where the legs extending in the vertical direction are positioned on the lower side, and the butterfly position where the two adjacent legs are directed obliquely upward. However, since the inverted position and the butterfly position are unstable on a plane, it is not realistic to store the blocks in these arrangement postures.

In the conventional method of installing a deformed block with a sling rope, which has been widely used, a crane is mounted on a deformed block in a normal position placed at a storage location by a method that is specific to the position of the crane. When the deformed block is lifted by the method, the deformed block rolls according to the way the rope is applied and is suspended in the arrangement posture, and after being placed in the installation position in that state, the rope is removed. It was.

However, not only is it troublesome to apply ropes to these odd-shaped blocks, but the work efficiency is not good, but the fall of the blocks, ground workers and diving workers are caught in the ropes, or they are swept by waves and collide with the blocks There was a problem with such dangers. For this reason, a clamping device in which three clamping arms are opened and closed by hydraulic pressure to clamp and deform the deformed block is disclosed in Patent Document 1 (Japanese Utility Model Laid-Open No. 3-18084) and Patent Document 2 (Japanese Patent Laid-Open No. Hei. 6-286973) and the like have been proposed.

Japanese Utility Model Publication No. 3-18084 JP-A-6-286773

However, the devices of Patent Document 1 and Patent Document 2 are attached to the wire taken out from the crane, and open / close the clamping arm by hydraulic pressure to grip the deformed block, and change the direction of the deformed block after gripping. I can't. For this reason, when the clamp device is used for installation, it is necessary to place the deformed block in a specific arrangement posture when gripping the deformed block.

In addition, the deformed block is a heavy object of several tens of tons and a maximum of 80 tons, so it is dangerous to reverse this to a specific arrangement posture on the ground, and the block is damaged by the impact of rotation. There was a problem to do. In addition, since the posture cannot be stably maintained on a plane in the inverted position and the butterfly position, it has been difficult to cause the clamp device to grip the block substantially in these arrangement postures. As a result, it has become an obstacle to using the clamping device in the installation work of the irregular block, and the clamping device is often used for specific applications such as removal of the irregular block.

Accordingly, an object of the present invention is to solve the above-described problem, and a deformed block reversing device capable of reversing a deformed block to an arrangement posture required in installation work or the like without requiring a large load and the device An object of the present invention is to provide a method for installing a deformed block using the.

The rotation control member is configured to be horizontally movable in both directions with respect to a position where the deformed block is placed on the placement portion, and the support surface includes an upper surface disposed at substantially the same height as the placement portion. It can be constituted by a front surface which is bent in a circular arc shape from the upper surface and is continuous. At this time, it is preferable that the upper surface is inclined so as to become lower toward the front surface.

The rotation control member may include a support roller that can rotate around a rotation axis along the facing direction of the mounting portion.

In addition, the odd block reversing device of the present invention includes a connecting portion suspended from a crane and a main body portion having a clamping claw that can be pivoted around the vertical axis with respect to the connecting portion and that can be opened and closed. It is preferably used in a method for installing the deformed block using the deformed block, and the deformed block placed at the storage position is placed on the reversing device of the deformed block by the clamping device.

The rotation control member 3 includes a support body 17 having a substantially rectangular parallelepiped shape and a caster 12 fitted to the guide rail 10.

The support body 17 supports the block B in a state where the upper surface is configured to be smooth and the block legs are placed on the upper surface 18. The upper surface 18 is configured as an inclined surface so that the left side shown in FIG. 3 is lowered, and continues to the front surface 19 with a curved surface. The upper surface 18 and the front surface 19 of the support body 17 constitute a support surface that supports the block.

The upper surface 18 of the support body 17 is configured to be substantially the same height as the upper surface of the mounting rail 13, and, as will be described later, the left and right mounting rails 13 and the upper surface 18 of the rotation control member 3 have 3 blocks B. One leg is held down, and the block B can be arranged in the normal position (see FIGS. 3 to 5).

Further, the casters 12 are provided at four positions, front, rear, left and right, of the support body 17 and are configured to be movable in the horizontal direction over almost the entire length of the mounting rail 13 by being guided by the guide rail 10 as described above. As will be described later, the rotation control member 3 is between a support position where the leg of the block B supported by the rotation control member is substantially the same height as the mounting rail 13 and a retracted position where the leg is lower than the mounting rail 13. Move with.

The rotation control member 3 is connected with a drive belt 20 wound around a drive belt guide roller 11 as a drive mechanism. The drive belt 20 is wound around a drive belt guide roller 11 provided in the base unit 5. One of the drive belt guide rollers 11 is moved integrally with the drive shaft 22 connected to the drive motor 21 by the drive belt 20 by the power of the drive motor 21 to move the rotation control member 3.

The reversing device 1 according to the present embodiment is used as follows when reversing the irregular block B. FIGS. 6A and 6B are schematic views showing a state in which the block is supported in the normal position, where FIG. 6A is a diagram viewed from the side surface, and FIG. 6B is a diagram viewed from the front side.

Hereinafter, in order to clarify the position of the block B in the three-dimensional space, the leg (first leg) extending in the vertical direction of the block is L1 in FIG. Of these, the leg (second leg) extending in the direction intersecting the mounting rail 13 is L2, and the leg (third leg) extending in the direction along the mounting rail 13 is L3. Further, in the following description, the normal position, which is an arrangement attitude that is stable on a plane and stored on the carriage 100, corresponds to the first attitude, and the inverted position and the butterfly position correspond to the second attitude, respectively.

The odd-shaped block B is a tetrapod (trade name) having four legs extending radially from the center, and is placed on the carriage 100 in the upright position. The clamp device 111 lifts the normal block B from the carriage 100.

In the block B, the turning direction is determined so that the third leg L3 fits between the mounting rails 13 in a state where the second legs L2 are arranged on the mounting rails 13, and the two second legs L2 Is mounted on the mounting rail 13 in the upright position so that the third leg L3 is supported by the rotation control member.

The mounting rail 13 is adjusted in advance according to the size of the block B, and a predetermined distance from the base portion of the second leg L2 so that the holding arm 34 of the clamping device 111 can be inserted. Is formed.

After the block B is placed, the drive motor 21 is operated to move the rotation control member 3 toward the placement position P1 as indicated by the arrow 121. As the rotation control member 3 slides, the support position P2 of the third leg L3 by the support body 17 moves to the base side of the third leg L3. Along with this, the block B rolls on the mounting rail 13 to the left in the figure so that the third leg L3 is on the lower side due to gravity.

In the process of rolling the block B, the center of gravity movement of the block B, that is, the magnitude and direction of the reaction force on the mounting rail 13 and the rotation control member 3 change, so that the block B slides on the mounting rail. In order to prevent this, the mounting rail 13 is inclined so that the left side in the figure becomes higher and provides resistance to slipping. As a means for preventing this slip, rubber lining or the like may be applied to the upper surface of the mounting rail 13 as described above.

As the block B rotates, the upper surface 18 and the front surface 19 of the support body 17 are continuous with the curved surface. Therefore, the support position P2 for supporting the third leg L3 by the support body 17 is smooth from the upper surface 18 to the front surface 19 side. Migrate to

When the rotation control member 3 moves to the right side of the figure from the mounting position P1, the block B is reversed to the inverted position as shown in FIG. In this state, the third leg L3 is supported by the front surface 19 of the support body 17, and the upper surface of the mounting rail 13 and the block B are prevented from slipping as described above. B is maintained in a stable posture in the inverted position.

When the rotation control member 3 further moves to the right side in the figure from the state shown in FIG. 7, the block B rolls due to gravity and assumes the butterfly position shown in FIG. In this state, the third leg and the first leg are balanced in the retreat area 30 below the mounting rail 13, and the block B is suspended by the mounting rail 13 by the second leg L2. Thus, even if the rotation control member 3 is not supported, the posture is stable.

It should be noted that the block B placed on the reversing device 1 can be suspended by the clamping device 111 in its posture. The clamping device 111 suspends the block B after inserting the clamping arm 34 of the clamping device 111 between the mounting rail 13 and the block B, then closing the clamping arm and gripping the base portion of the block. This is done by raising 111.

FIG. 9 is a schematic diagram showing the configuration of the clamp device 111. The clamp device 111 is connected to the connecting member 32 connected to the crane and the connecting member, and is supported along the outer periphery of the supporting body 33, which is connected to the connecting member 32 so as to be pivotable around the vertical axis.

By the lower end of the side wall 41, the base portion R of the block can approach the lower end of the side wall 41 to maintain the posture of the block B, and the tip end side of the holding arm reaches the leg base portion R of the block B and is stable. It is possible to hold it. As shown in FIG. 10, when the head / leg portion H of the odd-shaped block is not inserted into the storage space 43, the block B is lifted because the base portion of the block B is disposed so as to approach the lower end of the side wall 41 of the cap portion 40. In this case, even if the block B is inclined, the inclination of the block is limited by contacting the lower end of the side wall 41.

The clamp device 111 inserts the head and leg portion H into the storage space when the block B is in the normal position, and the base portion R of the block approaches the lower end of the side wall 41 in the inverted position and the butterfly position. By gripping the block, it is possible to grip the block B while preventing the block B from falling.
