High-safety crane hoisting hook device

Abstract

The invention relates to a high-safety crane hoisting hook device. The high-safety crane hoisting hook device comprises a hook subassembly, a first connecting rod, a second connecting rod and a third connecting rod, wherein the first connecting rod, the second connecting rod and the third connecting rod are sequentially connected to one another end to end; the hook subassembly comprises a first hook and a second hook; one end of the second connecting rod is fixedly connected with the first hook; and the other end of the second connecting rod is fixedly connected with the second hook. The high-safety crane hoisting hook device has the advantages that by the high-safety crane hoisting hook device, the center of gravity of a long workpiece is not required to be sought deliberately, a hoisting process can be stable, and potential safety hazards of high-altitude falling of workpieces in the hoisting process are reduced.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a crane hook device, which can safely lift long workpieces. Background technique [0002] Crane is a kind of common lifting equipment, which is favored by users. The driving operation is stable and reliable, and the carrying capacity is strong. But existing driving also has following deficiencies. The disadvantage is that when lifting a workpiece with a long size, the center of gravity of the workpiece must be found. Otherwise, the movement of the crane during the lifting movement will drive the workpiece to shake at high altitude, thus causing the workpiece to fall from high altitude. Bring certain hidden dangers to production. Contents of the invention [0003] The present invention overcomes the disadvantages of the background technology and provides a high-safety crane lifting hook device. The device does not need to deliberately search for the center of gravity of a long workpiec...
