Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

As shown in fig. 1, the embodiment provides a high-safety lifting jig, which includes an electric hoist lifting hook 1, wherein the electric hoist lifting hook 1 is located at the lower end of an electric hoist (not shown in the figure), four steel wire ropes 2 are connected below the electric hoist lifting hook 1, a first lifting ring 3 is penetrated through any one of the first steel wire ropes 2, a steel plate 4 is arranged below the four first lifting rings 3, the upper and lower sides of the steel plate 4 are flat, the first lifting rings 3 are fastened to first bolt holes 10 on the upper sides of four corners of the steel plate 4 through bolts, an included angle between any one of the first steel wire ropes 2 penetrating through the first lifting ring 3 and the horizontal plane of the steel plate 4 is equal, when the electric hoist lifting hook 1 is lifted, a pulling force on the electric hoist lifting hook 1 is transmitted to the first lifting ring 3 through the first steel wire rope 2, and an included angle between any one of the first steel wire ropes 2 and the horizontal plane of the steel plate 4 are equal, so that a pulling force on the first, because first rings 3 evenly distributed is in 4 four corners of steel sheet, so the pulling force that transmits on the steel sheet 4 is even to steel sheet 4 can play the effect of balanced electric hoist pulling force, 4 four corners downside of steel sheet are equipped with four second rings 5, four second rings 5 pass through bolt fastening and connect in the second bolt hole 9 of steel sheet 4, four second rings 5 are located the outside of first rings 3, four second rings 5 all have passed a lifting hook 7 through second wire rope 6, when lifting by crane the heavy object, four lifting hook 7 homoenergetic bears lifting by crane thing gravity, can with lifting by crane thing gravity dispersion to 4 four corners of steel sheet, reduce the potential safety hazard, reduce staff intensity of labour.
