Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lifting tool for a retaining wall block.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, the lifting / installation work of retaining wall blocks used for retaining soil such as building land has been done by lifting / installing sling ropes through the hanging holes formed in the retaining wall of the block. However, it was difficult to install the block at the desired position because the lifting posture of the block was unstable.

When the upper end of the retaining wall of the retaining wall block is clamped and lifted by a holding-type lifting tool, sometimes the upper end of the lifting tool is cracked or scratched by the holding body of the lifting tool, which is dangerous. There was a flaw that impaired the appearance.

When the applicant inserts the protruding locking rod at the lower end of the suspension rod into the suspension hole formed in the retaining wall of the retaining wall block and lifts the head, the retaining rod is retained in the suspension hole. The present invention has been completed focusing on the fact that the retaining wall block can be lifted at a stable inclination angle.

[0005]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A locking rod 3 to be inserted into a suspension hole 2 formed in the retaining wall 1 of the retaining wall block a is projected from the lower end of a suspension rod 4, and a lifting connection portion 5 is provided on the head of the suspension rod 4. The present invention relates to a retaining wall block lifting device characterized by the above.

[0007]

[Action]

 When the locking rod 3 is inserted into the hanging hole 2 formed in the retaining wall 1 of the retaining wall block a and the head is lifted, the connecting portion 5 is lifted, and it is retained due to the relationship between the suspension fulcrum and the center of gravity of the retaining wall block a. Since the wall block a is slightly tilted and the locking rod 3 is locked in the hanging hole 2, the retaining wall block a is lifted at a stable inclination angle, and the retaining wall block a is moved to a desired position and installed in that posture. To do.

[0008]

【Example】

 The drawings illustrate a preferred embodiment of the present invention.

The retaining rods 3 and 3 provided with the protruding rods 4 and 4 are inserted into the suspension holes 2 and 2 provided in the retaining wall 1 of the L-shaped retaining wall block a, and the lifting connection portion 5 of the head is connected.・ When 5 is hoisted, the position of the center of gravity of the retaining wall block a and the suspension fulcrum of the hoisting connection part 5 are on the same vertical line when hoisted, so the retaining wall block a is slightly inclined and the locking rod 3 is formed. The retaining wall block a and the hoisting tool are hoisted in the suspension hole 2 in a twisted state, and the retaining wall block a and the hoisting tool are hoisted at a stable inclination angle, and can be lowered as it is in that posture, so that the retaining wall block a is easily installed.

When a step portion 6 is formed on the base of the locking rod 3 as shown in the figure, the hanging hole end edge portion of the retaining wall 1 comes into contact with the step portion 6 and wobbles when the retaining wall block a is lifted. Can be prevented.

[0011]

[Effect of device]

 According to the present invention, the locking rod to be inserted into the suspension hole formed in the retaining wall of the retaining wall block as described above is provided at the lower end of the suspension rod, and the lifting connection portion is provided at the head of the suspension rod. A retaining wall block hoisting device that has a simple structure and is extremely practical, which allows the retaining wall block to be lifted at a stable inclination angle, moved in that position, and then lowered and installed as is.
