[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lifting device used when lifting and transporting construction concrete blocks using a rope such as a crane.

(Prior art) Conventionally, as a hanging device, there has been a device described in Japanese Utility Model Application Publication No. 52-63857 (hereinafter referred to as the first conventional example) and a device described in Japanese Utility Model Application Publication No. 59-165882 (hereinafter referred to as the second conventional example). Conventional example) is known.

The first conventional example is a "cantilevered cargo handling hoist with a fork, and the L-shaped main body has a horizontal fork part on the leg and a continuous rising part on the base end, and and a continuous upwardly inclined arm, the lower end of which supports the load of the cargo when the hoist receives cargo by the fork, is attached to the tip of the upwardly inclined arm. an auxiliary suspension member whose lower end is attached to the base end of the upwardly inclined arm; It is characterized by having a support mechanism for the main body consisting of a main elastic hanging member attached to the tip of the upwardly inclined arm and an auxiliary elastic hanging member whose lower end is attached to the base end of the upwardly inclined arm. The above-mentioned lifting equipment for cargo handling."

The second conventional example is a lifting jig used for lifting architectural panels in a substantially horizontal state, and includes an L-shaped hook near one end of the board, and this hook and a stop member consisting of a connecting part and a hooking part and rotatably pivoted to the supporting part of the substrate. Jig.”

(Problems to be solved by the invention) The first conventional example requires many elastic members and does not have a mechanism to prevent the cargo from shifting in the lateral direction, so it is not suitable for lifting objects such as concrete blocks. Not suitable. In addition, the lack of a handle for transporting and operating the hanging equipment was very inconvenient and resulted in poor workability.

The second conventional example is a jig that supports and lifts something like a horizontal panel from the side.
Like the conventional model, there is no structure to prevent lateral slippage, making transportation and
It was not designed with ease of use in mind.

(Means for Solving the Problems) The concrete block hoist of the present invention is a hoist used when hoisting a concrete block with a crane. A hanging tool equipped with a receiving part formed to protrude from above so that the bottom of a concrete block can be placed on it, and a handle rod protruding from the center of the upper edge of the back plate part in the same direction as the above-mentioned receiving part. It consists of a main body and a clamping member that is rotatably supported vertically in a shaft hole formed in the middle of the handle rod, and the clamping member has an upper plate and a tip edge of the upper plate that is bent downward. A clamping part is formed with a hook plate.
The clamping part is arranged along the back plate of the suspension main body, and the concrete block is held between this clamping part and the receiving part of the suspension main body, but there are two mounting plates on the top surface of the top plate. are erected at a predetermined parallel interval, a through hole is formed slightly above the center of both mounting plates to pass through the end, and a through hole is formed at the upper rear corner of both mounting plates. Both ends of the hanging bracket that connects the tip of the crane's rope are rotatably locked.The handle rod is inserted between the mounting plates, and the shaft is inserted into the matching through hole of the mounting plate and the shaft hole of the handle rod. The suspension main body and the clamping member are assembled by penetrating through the suspension member.

(Operation) A concrete block is placed on the main body of the lifting device, and the end of the rope of the crane is tied to the hanging fitting of the lifting device to lift and transport the concrete block. When the concrete block is lifted by the crane, the lifting fitting of the lifting tool is pulled upward and the clamping member is rotated downward, so that the concrete block is moved between the clamping part of the clamping member and the receiving part of the lifting tool body. It is transported while being held in place.

Since the clamping member is formed with a clamping part, there is no problem of the concrete block slipping laterally and falling, and since the gripping rod is provided, it is very convenient to operate and transport the hanging device, and the workability is good.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a concrete block hoist according to the present invention.

In the figure, reference numeral 1 denotes a suspension main body, and this suspension main body 1 includes a flat back plate portion 11 that contacts one side of a concrete block B, and a back plate portion 11 on which the bottom of the concrete block B is placed and supported. A receiving portion 1 formed in a hook shape at the lower edge of the plate portion 11
It is formed from 2. The back plate part 11 has a central part 1 so as to leave the peripheral edge of the back plate part 11 in the shape of a forehead line.
3 is cut out, thereby reducing the weight of the suspender main body 1 and reducing manufacturing costs.

A handle rod 14 is fixed substantially horizontally to the substantially central portion of the upper edge of the back plate portion 11. The handle rod 14 is for a worker to hold when transporting or loading or unloading the concrete block B, and is provided protruding from the same side as the receiving part 12. Handle rod 14
A clamping member 2 is pivotally attached to a midway portion thereof so as to be rotatable in the vertical direction. 15 is a shaft hole, and 16 is a grip portion. The clamping member 2 consists of an upper plate 21 and a hook plate 22 which is bent downward at the tip edge of the upper plate 21.
6 is formed.

The clamping part 26 is disposed along the back plate part 11 of the suspension main body 1 and is formed so that the concrete block B is clamped between this clamping part 26 and the receiving part 12 of the suspension main body 1. Two mounting plates 23, 23 are erected on the upper surface at a predetermined parallel interval. This interval is large enough to allow the handle rod 14 to be inserted between the two mounting plates 23, 23.
Both mounting plates 23, 23 are formed with through holes 24, 24 slightly above the center portion thereof, through which the shaft 4 passes.
Also, locking holes 25, 25 are formed in the rear upper corners of both mounting plates 23, 23 to rotatably lock both ends of the hanging fitting 3 for binding the tip of the rope 5 of the crane.

The clamping member 2 is assembled to the suspension main body 1 as follows.

The handle rod 14 is inserted between the mounting plates 23, 23, the through holes 24, 24 are matched with the shaft hole 15, and the shaft 4 is passed through this matching hole. In this way, the clamping member 2
The handle rod 14 can be rotated vertically using
can be attached to. Further, both ends of the hanging fitting 3 are rotatably locked in the engagement holes 25, 25.

The clamping part 26 of the clamping member 2 and the receiving part 12 of the suspension main body 1 are opposed to each other on the diagonal line of the concrete block B to be clamped.

The tip of a rope 5 hanging from a crane is tied to a hanging fitting 3 attached to the clamping member 2. When the rope 5 is lifted, the clamping part 26 of the clamping member 2
can be rotated downward about the shaft 4 as a fulcrum so as to approach the back plate portion 11 of the suspension main body 1. Conversely,
When lifting of the rope 5 is stopped, the clamping part 26 of the clamping member 2 can be rotated in a direction away from the back plate part 11 of the hanging tool main body 1.

Next, using the hanging device configured as above,
The case where concrete block B is transported by an overhead crane will be explained.

First, the concrete block B has its side surface aligned with the back plate part 11 of the suspension main body 1, and the bottom part
The holding part 26 of the holding member 2 is brought into contact with the front upper corner of the concrete block B.
Then, attach the tip of the crane rope 5 to the hanging bracket 3.
and lift concrete block B. By lifting the concrete block B, the hanging fitting 3 is pulled upward, and thereby the holding portion 26 of the holding member 2 is rotated downward about the shaft 4. As the clamping part 26 rotates downward, the concrete block B is clamped between the clamping member 2 and the receiving part 12 of the suspension main body 1, and the concrete block B is slid down from the suspension main body 1 by the clamping part 26. It will be in a locked state to prevent it from happening. Therefore, the concrete block B is lifted while being clamped and fixed between the clamping member 2 and the receiving part 12 of the lifting tool main body 1, and is safely transported without falling accidentally.

Then, the concrete block B transported by the crane is lowered onto the ground or onto a loading platform, and the rope 5
When the pulling up of the concrete block B is stopped, the clamping member 2 becomes able to rotate upward about the shaft 4, and the clamping of the concrete block B between the clamping part 26 and the receiving part 12 of the hanger main body 1 is also released. Therefore, the concrete block B can be easily removed from the hanging fixture. The hanging tool from which the concrete block B has been removed can be easily moved to the location where the next concrete block B is located by holding the handle rod 14.

(Effects of the invention) As described above, by using the lifting device of the present invention, concrete blocks can be lifted and transported by a crane, which eliminates the need for a large amount of labor that would otherwise be required for manual transportation. This makes transportation work easier. Also, during transportation, the concrete block is held between the holding part of the holding member and the receiving part of the lifting device body, and
Since the concrete block is suspended in a locked state by the clamping part to prevent it from slipping off the lifting tool body, the block can be safely transported without falling accidentally.

In addition, since the sling body is equipped with a handle rod,
The hanging equipment can be easily transported, moved, and operated, and concrete blocks can be easily attached and removed from the hanging equipment.
