The invention relates to a double-rope grab three-multiplying-power duplex structure. A deck beam is hinged with a support rod, and the lower end part of a through beam is hinged with a hopper body; the lower end part of the support rod is hinged with the middle part of the back of the hopper body; the left end part of the upper surface of the deck beam is provided with a first steel rope guide wheel; the right end part of the upper surface of the deck beam is provided with a second steel rope guide wheel; the deck beam is provided with a first deck beam pulley and a second deck beam pulley; the through beam is provided with a first through beam pulley, a second through beam pulley and a third through beam pulley; a lifting frame is arranged above the deck beam, the left end part of the lifting frame is provided with a first cable shackle; the right end part of the lifting frame is provided with a second cable shackle; the second cable shackle is connected with a cable by a second rigging sleeve ring. The double-rope grab three-multiplying-power duplex structure provided by the invention is safe in structure, is uniform in stress in opening and closing a grab so as to enable the grab to be stable and not tilt. The stress of the cable is less than the stress of a common double-rope three-multiplying-power grab, and the smaller cable can be selected in model selection of a cable rope.
Description
technical field [0001] The invention relates to a grab structure, in particular to a double-rope grab triple-rate duplex structure. Background technique [0002] One end of the opening and closing wire rope of the traditional double-cable grab is fixed on the bolster of the grab, and the other end extends to one side of the upper bolster to connect with the opening and closing cable of the crane. smooth. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a double-rope grab triple-rate double-connected structure with a safe structure, uniform force when the grab is opened and closed, keeping the grab stable, and less resistance to the cable . [0004] According to the technical solution provided by the present invention, the double-rope grab triple-rate double structure includes an upper bolster and a lower bolster, a strut is hinged on the upper bolster, and a bucket body is hinged on the ...
