Embodiment Construction
[0024] Such as figure 1 , figure 2 and image 3 As shown, a steel plate with a hole is flipped and lifted, including a clamping end 7 and a shackle 1 fixedly connected to a lifting lug arranged on the upper end of the clamping end 7 . The lower end surface of the clamping end 7 is provided with a U-shaped groove, and the groove width of the U-shaped groove is L, and L satisfies: L≥b, wherein b is the thickness of the steel plate 15 with holes, and the inner wall of the U-shaped groove A backing plate 2 is provided, and the backing plate 2 is fixed on the lower end surface of the clamping end 7 through a washer and a screw. The backing plate 2 can effectively prevent scratches on the surface of the processing surface caused by the direct contact between the steel plate with holes 15 and the U-shaped groove, etc. ; The clamping end 7 is provided with a positioning through hole I12 that matches the positioning shaft 11. In this embodiment, the number of the positioning through...

The invention discloses a tool for overturning and lifting of a steel plate with holes and its using method. The tool comprises a clamping end and a shackle that is fixedly connected with a lifting lug arranged at the upper end of the clamping end. Besides, the provided tool is characterized in that: a U-shaped groove is arranged at the lower end surface of the clamping end and a positioning through hole I that is matched with a positioning shaft is arranged on the clamping end; and a positioning through hole II is arranged between the top end of the U-shaped groove and the upper end surface of the clamping end. One end of a pin roll is fixed inside the positioning through hole II by a roll sleeve and the other end of the roll sleeve is provided with a baffle plate and a lifting ring, wherein the baffle plate can be rotated around the pin roll by any angle. Two baffle plate limit holes are arranged above the positioning through hole II and springs are arranged inside the baffle plate limit holes; pressure bars are arranged at the front ends of the springs; the front ends of the pressure bars are projected out of one ends of the baffle plate limit holes; and the tail ends of the springs are fixed with the other ends of the baffle plate limit holes by fastening components. According to the invention, the characteristics of simple structure, strong practicability and high reliability and security and the like are realized.
Description
technical field [0001] The invention relates to a sling, in particular to a tool for turning and hoisting a steel plate with holes and a method for using the same. Background technique [0002] At present, steel plates with holes, especially round steel plates with holes, are mostly processed from medium-thick steel plates or stainless steel plates, and hundreds of uniformly distributed special-shaped holes are formed through drilling and broaching. During the whole processing process, the round steel plate needs to be formed by changing the broach several times. The two sides of the steel plate must not only be cleaned, ground and finished, but also placed vertically, which requires repeated horizontal, vertical and flipping hoisting. . Since the round steel plate cannot be turned over and lifted by the pliers spreader after finishing, and the clamping position is limited. Therefore, it is necessary to design a special spreader and a lifting and turning process to realize...
