[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0021] The crane lug plate set of the embodiments of the present application is described below with reference to the drawings.

[0022] As Figure 1 - Figure 4As shown, the crane ear plate assembly of the embodiment of the present utility model includes: an ear plate assembly 1, a bolt 2 and a buffer mechanism 3.

[0023] The lug plate set 1 includes a connecting plate 11 and two lug plates 12 .

[0024] The two lug plates 12 are symmetrically arranged at the bottom of the connecting plate 11 , and the bolt 2 passes through one lug plate 12 and is threadedly connected to the other lug plate 12 .

[0025] The buffer mechanism 3 includes multiple groups of telescopic columns 31 , multiple groups of springs 32 and a push plate 33 .

[0026] Among them, multiple groups of telescopic columns 31 are equidistantly distributed on the lower wall of the connecting plate 11, the push plate 33 is connected to the other end of the multiple groups of telescopic columns 31, and multiple groups of springs 32 are respectively sleeved on the outside of the corresponding telescopic columns 31, and the multiple groups of springs 32 are respectively arranged on the lower wall of the connecting plate 11, and the other end of the multiple groups of springs 32 is connected to the push plate 33.

[0027] Specifically, when the lifting requires lifting an object through the ear plate group 1, first hang the wire rope on the hook of the crane, then pass the connecting plate 11 through the other end of the wire rope, then pass another wire rope through the object and place it on the connecting plate 11, pass the bolt 2 through one of the two ear plates 12 and then thread it into the other one, thereby fixing the cable in the connecting plate 11, so that the crane can lift the object through the ear plate group 1.

[0028] During lifting, the crane drives the wire rope upward, and the wire rope applies an upward force to the ear plate group 1. At this time, the force will be evenly applied to each spring 32 through the push plate 33. At this time, the telescopic column 31 contracts to limit the movement trajectory of the spring 32. The contraction of the spring 32 buffers the impact force, preventing the initial impact of the crane from damaging the wire rope.

[0029] like Figure 2 - Figure 3 As shown, in the crane ear plate assembly of the embodiment of the present invention, the side wall of the connecting plate 11 is symmetrically provided with a sliding groove 111 , and the two ends of the push plate 33 are symmetrically provided with a slider 41 , and the slider 41 can slide inside the sliding groove 111 .

[0030] It is understandable that the arrangement of the slider 41 and the slide groove 111 can limit the movement trajectory of the push plate 33 when it moves up and down.

[0031] like Figure 1 - Figure 2 As shown, in the crane ear plate assembly of the embodiment of the present invention, the bottom wall of the push plate 33 is provided with a rubber pad 5.

[0032] It can be understood that through the arrangement of the rubber pad 5, the damage to the steel wire rope caused by friction between the steel wire rope and the connecting plate 11 can be minimized.

[0033] As shown in Figure 1 - Figure 2 The utility model discloses ear plate group of crane, one of two ear plates 12 is equipped with through -hole 121.

[0034] It can be understood that through the arrangement of the through -hole 121, the bolt 2 can pass through the ear plate 12 better.

[0035] As shown in Figure 1 And Figure 4 The utility model discloses ear plate group of crane, and the outer wall of bolt 2 is equipped with limit groove 21.

[0036] Specifically, through the arrangement of the limit groove 21, the steel wire rope inside the ear plate group 1 can be limited, so as to prevent the frequent movement of the internal steel wire rope, so as to prevent the breakage of the steel wire rope caused by friction.

[0037] In conclusion, the utility model discloses ear plate group of crane, can buffer the initial impact when the crane is initially lifted, thereby protecting the steel wire rope, and preventing the breakage of the steel wire rope caused by impact.
