Detailed Description

In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

The embodiment provides a special lifting appliance for blades of a steel plate shearing machine, and the special lifting appliance comprises two first hinged arms 1, wherein the upper ends of the two first hinged arms 1 are hinged with each other, and the hinged points are in transmission connection with a crane through transmission rods 6. The two first hinge arms 1 are rotatable about the hinge point in a vertical plane.

At the lower ends of both first hinge arms 1, a second hinge arm 2 is articulated, which second hinge arm 2 can be pivoted about the articulation point in a vertical plane. The middle portions of the two second hinge arms 2 are hinged to each other, and referring to fig. 1, when the two second hinge arms 2 are rotated about the hinge point of the middle portions, the lower ends of the two second hinge arms 2 can be moved toward or away from each other.

Hanger rods 4 are welded to the lower ends of the second hinge arms 2, and each hanger rod 4 extends in the length direction of the second hinge arm 2 connected thereto. The lower end of each suspender 4 is provided with a hoisting part 3. Referring to fig. 2, the sling 3 is perpendicular to the plane of the first hinge arm 1 and the second hinge arm 2.

Referring to fig. 3, a plurality of blade holes 7 are equidistantly formed in the blade of the steel plate shearing machine along the length direction thereof. The two sling portions 3 extend into the two blade holes 7, respectively. In the hoisting process, the crane applies a hoisting force to the lifting appliance through the transmission rod 6, and then the lifting appliance hoists the blade. In the process of lifting, receive gravity and pulling force effect, the contained angle between two first articulated arms 1 reduces gradually, and the contained angle between two second articulated arms 2 reduces gradually afterwards, makes the interval between two hoist and mount portions 3 reduce, and two hoist and mount portions 3 play certain clamping action to the blade, lift the blade at last.

In addition, referring to fig. 4, the diameter of each insert hole 7 is gradually reduced from both sides of the insert toward the inside of the insert. Therefore, a limit projection 5 is provided on the right side of the sling 3 on the left side, see fig. 5. Correspondingly, a limiting convex block 5 is arranged on the left side of the hoisting part 3 on the right side. The limiting convex blocks 5 are all arc-shaped, and the thickness of the two ends of each limiting convex block 5 is larger than that of the middle part of each limiting convex block 5. When the hoisting part 3 extends into the blade hole 7, the shape of the limiting lug 5 is matched with that of the blade hole 7, and both ends are wide and the middle part is narrow. When hoisting, two ends of the limit lug 5 are respectively embedded at two ends with larger diameters of the blade holes 7, see fig. 6, so that the clamping force of the hoisting part 3 on the blade is improved.

In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
