Description

[Detailed Description of the Invention] The present invention relates to a gripping tool for concrete products, etc.

Conventional concrete products are provided with hanging hooks, and the concrete products are lifted and transported via the hooks.

However, when manufacturing this concrete product, the provision of the hook increases the number of steps, and when constructing this concrete product, it is often necessary to remove the hook.

Furthermore, when the concrete products are stacked for storage before construction, it becomes necessary to rotate them around a horizontal axis while hoisting them, but such rotation is not possible when the concrete products are lifted using the hooks. It is.

The present invention was devised to solve the above-mentioned problems of the prior art, and is a method for easily and reliably rotating an object, such as a concrete product, around a substantially horizontal axis in a suspended state. It is an object of the present invention to provide a gripping tool equipped with a simple rotation device.

Underground, the present invention will be described according to an illustrative embodiment.

In Fig. 1, 1 is the main body of the gripping tool A, and the horizontal part 1
A vertical portion 1b is integrally provided on one side of a.

This vertical portion 1b may be provided so as to be slidable left and right with respect to the horizontal portion 1a.

A gripping portion 2a is provided inside the lower end of the vertical portion 1b and is capable of coming into contact with the U of the object B to be gripped.

A guide plate 3 is provided hanging down on the other side of the horizontal portion 1a, and a movable body 4 of the gripping tool A is provided at the lower end of the guide plate 3.
is supported.

The movable body 4 has an angular shape, and has the above-mentioned pivot point 5 on one side 4a, and has a grip portion 2b that can come into contact with the other side of the object B inside the lower end of the side 4a. It is provided.

The other side 4b of the movable body 4 faces above the horizontal portion 1a.

A lifting chain 11 is attached to the end of the negative side 4b, and a ring 6 is also provided.

The ring 6 is capable of engaging with a hook γ planted in the horizontal portion 1a.

8 is a guide installed above the horizontal portion 1a;
The above-mentioned negative side 4b is held between the front and rear to properly guide its movement in the vertical direction.

Reference numeral 9 is a stopper for determining the position of the gripping portions 2a, 2b in contact with the object B, and is an auxiliary member for rotating the object B around a substantially horizontal axis.

The stopper/rotation auxiliary member 9 is provided protruding from the left and right inner sides of a gate-shaped lever 10 that is suspended between the main body 1 and the movable body 4 and is rotatable, and its planar shape is similar to that of the target object. It forms an annular shape that contacts the end face of B in a loop shape (see Fig. 4).

The lower ends of both sides of the gate-shaped lever 10 are provided with left and right grip portions 2a, respectively.
, 2b, and the posture of the object B can be changed.

The gate-shaped lever 10 is formed of a single rondo,
In some cases, the upper portions of the two rondos are overlapped to make it possible to expand and contract the distance between the left and right sides (see Figure 3).

Further, the lower left and right portions of the lever 10 may be made of plate material with high spring properties.

The auxiliary member 9 may be provided on either the left or the right car side.

Reference numeral 12 denotes a spring that normally holds the lever 10 parallel to the main body 1.

Each gripping portion 2a, 2b is adapted to abut on each side of the object B at one or two points.

Therefore, for example, if the grip part 2a contacts the object B at two points on one side, and the grip part 2b contacts the other side of the object B at two points, then the object B is adapted to be gripped at four points on the side surface and moved to a predetermined position by the gripping tool A (see Fig. 4).

Next, the main functions of the gripping tool A configured as described above will be explained together with its usage.

■ Transporting to object B (Fig. 1.3) With ring 6 and hook γ locked, hold left and right grips M
A gripping tool A, in which the interval between 2a and 2b is held wider than the left and right gripping widths of the object B, is suspended from above the object B.

At this time, first, the left and right stopper/rotating members 9, 9 come into contact with the left and right upper ends of the object B, and the gripping parts 2a, 2b become operable, so that the ring 6 and the hook γ are engaged with each other. Release the stopped state.

When the lifting chain 11 is pulled out, the movable body 4 rotates clockwise around the pivot point 5.

At this time, the left and right gripping parts 2a and 2b first come into contact with the left and right side surfaces of the object B, and when the chain 11 is further pulled up, the left and right gripping parts 2a and 2b respectively touch the object B.
The object B is lifted up while being gripped by the gripping parts 2a and 2b, and is moved to a predetermined position in the 1\ position.

■ Changing the posture of object B (Figs. 2 and 4) When the gate-shaped lever 10 is rotated by a predetermined angle against the bias of the spring 12 while object B is suspended, the object B
The rotation assisting member 9 changes the posture by a predetermined angle about the line connecting the left and right gripping parts 2a and 2b.

Therefore, for example, in order to stack objects B in a state in which they are laid down at 90 degrees with respect to the horizontal axis, it is sufficient to lift the object B, turn the lever 10 by 90 degrees, and stack the object B one after another.

As mentioned above, the button of the present invention is to connect the ends of a connecting rod for a lever that allows both sides of the grip to be rotated at the same time, and to use the connecting rod to determine the grasping position of an object and Since the gripping device is configured with a stopper and rotation auxiliary member that reinforces the rotation of the object, it can be rotated while the object is lifted, allowing the posture of a heavy object to be changed easily, quickly, and easily. Allows for stable stacking and storage of items.
