Therefore, the safety is very low.
In addition, even when arranging garden stones in a suspended state for landscaping, the crane has a low degree of freedom of movement, the position of the cranes tends to be inaccurate, and the work efficiency is very poor.

In view of this, the main object of the present invention is to eliminate the conventional work method using a crane vehicle and to provide high mobility.
An object of the present invention is to provide a large rotating glove that uses a power shovel that can freely move in a special terrain and can hold a huge stone of 30 tons or more and rotate it arbitrarily.

[0005]

In order to achieve the above object, the present invention provides a fixed seat provided with a connecting plate for connecting to a beam arm of a power shovel on the upper part, and a fixed seat installed on the upper part of the fixed seat. Oil input and oil output by three hydraulic pipes,
A rotary pump that processes residual oil and is operated by connecting with a hydraulic pipe of a power shovel, and is provided in the lower portion of the fixed seat,
The internal gear meshes with the gear of the rotary pump, and is connected to the rotary disc that can be rotated in the forward and reverse directions by the transmission of the rotary pump, and is connected to the lower portion of the rotary disc. There are two sets of rotating arms that rotate so that the tips move toward and away from each other, and the tips of the projecting shafts are connected to the rotating arms at the upper part. A large rotary grab was constructed from a base seat on which a hydraulic jack that was centrally connected to a hydraulic pipe and operated was pivotally installed.

[0006]

Since the present invention has the above-mentioned structure, it has the following effects.

The large rotary glove according to the present invention can be moved in all directions by being connected to the beam arm of a power shovel by a connecting plate provided on a fixed seat. Two sets of rotating arms that rotate so as to move toward and away from each other and a hydraulic jack in which each hydraulic pipe is connected to a hydraulic pipe of a power shovel are pivotally installed at the base to operate the hydraulic system of the power shovel. Open and close each rotating arm to grip large heavy objects.
Release can be done. In addition, the base is connected to the lower part of the turntable that rotates in the forward and reverse directions by the transmission of the rotary pump, and the rotating arm rotates together with the turntable. Can be selected. Rotation of the turntable is operable on the power shovel side, since each hydraulic pipe of the rotary pump is connected to the hydraulic pipe of the power shovel. In addition, each hydraulic pipe for oil input and output processing of the hydraulic jack is concentratedly connected to the hydraulic pipe of the power shovel, and the tip of the rotating arm is a movable clamp claw, so the external shape of large heavy goods can be bent. And it is possible to clamp firmly according to the uneven condition.
