As shown in fig. 1 and 2, the present invention includes a steel wire rope 4 and two hook assemblies with the same structure, wherein the steel wire rope 4 is a sealing steel wire rope with two sealed ends, and the two hook assemblies are oppositely disposed on two sides of the bottom of the steel wire rope 4; each lifting hook component comprises a lifting hook body 1, a fixed pulley 3 and two connecting plates 2 arranged in parallel, one end of the lifting hook body 1 and the fixed pulley 3 are both positioned between the two connecting plates 2, the same end of each connecting plate 2 is hinged with one end of the lifting hook body 1, and the other end of each connecting plate 2 is rotatably connected with the fixed pulley 3; one end of the steel wire rope 4 bypasses the fixed pulleys 3 of the two hook assemblies and then is sealed with the other end of the steel wire rope 4, and the steel wire rope 4 is connected with the two fixed pulleys 3 in a sliding manner; the lifting hook body 1 comprises a connecting part 1-1, a bending part 1-3, a supporting arm 1-4 and a supporting part 1-2 which are sequentially arranged, and the connecting part 1-1, the bending part 1-3, the supporting arm 1-4 and the supporting part 1-2 are integrally formed; the bending part 1-3 is positioned between the connecting part 1-1 and the supporting arm 1-4, an included angle formed between the connecting part 1-1 and the supporting arm 1-4 is 90 degrees, the supporting part 1-2 is arranged at the lower end of the supporting arm 1-4, and the supporting part 1-2 and the connecting part 1-1 are both positioned at the same side of the supporting arm 1-4; the outer end of the connecting part 1-1 is positioned between the two connecting plates 2, and the outer end of the connecting part 1-1 is hinged with the two connecting plates 2.
As shown in fig. 3, in the in-service use process, the utility model discloses use in pairs, two pairs of steel sheet lifting hooks are placed along steel sheet 5's length direction's well vertical plane symmetry, and wire rope 4 hangs on the driving lifting hook, makes steel sheet 5 keep balance, prevents at the in-process of handling steel sheet 5, and steel sheet 5 slopes or even landing. The top surface of the support part 1-2 must have certain roughness, so as to increase the friction between the steel plate 5 and the support part 1-2 and prevent the steel plate 5 from sliding off.
As shown in figures 1 and 2, the supporting part 1-2 is in a wedge-shaped structure, the end of the supporting part 1-2 far away from the supporting arm 1-4 is the tip of the wedge-shaped structure, and the bottom surface of the supporting part 1-2 is provided with an arc-shaped surface 1-5. When the steel plate 5 is lifted, both sides of the steel plate 5 are placed on the top surfaces of the support parts 1-2 on the corresponding sides. And often a plurality of steel plates 5 are stacked together in a factory, and the supporting part 1-2 is designed to be of a wedge-shaped structure, so that the tip end of the supporting part 1-2 can be quickly inserted into a gap between adjacent steel plates 5, and the lifting operation is convenient. The bottom of the steel plate 5 is set to be the arc-shaped surface 1-5, so that when the supporting part 1-2 is inserted into the gap between the adjacent steel plates 5, the friction force between the supporting part 1-2 and the adjacent steel plate 5 below the steel plate 5 to be lifted is small, the steel plate 5 below is prevented from being scratched, and meanwhile, the working efficiency can be improved.
The lifting hook body 1 is hinged with the connecting plate 2 through a first bolt 6. The connecting plate 2 is rotatably connected with the fixed pulley 3 through a second bolt 7. The utility model discloses in use the bolt to realize articulated and rotate the function of connecting, the other end threaded connection of screw rod has the nut on the bolt, and the bolt has higher intensity as the standard component, and threaded connection easily dismantles, is convenient for change spare part.
As shown in fig. 1 and 3, the left side and the right side of the steel plate 5 are respectively clamped on the supporting parts 1-2, the steel wire rope 4 is wound around the two fixed pulleys 3 and hung on the travelling crane hook, and the two fixed pulleys 3 and the travelling crane hook are both connected with the steel wire rope 4 in a sliding manner. When the crane hook rises upwards, through the utility model discloses the in-process that lifts up steel sheet 5 because connecting plate 2 is articulated mutually with lifting hook body 1 through first bolt 6, and connecting plate 2 rotates with fixed pulley 3 through second bolt 7 and is connected, under the action of gravity of steel sheet 5, when wire rope 4 drove the vertical upward movement of one end of connecting portion 1-1 through fixed pulley 3 and connecting plate 2, connecting portion 1-1 swung downwards around first bolt 6. Therefore, the hook body 1 moves and simultaneously drives one end of the connecting plate 2 to swing downwards around the second bolt 7, so that the fixed pulley 3 receives acting force f from the connecting plate 2 which is obliquely downwards and towards the outer side1. After the steel plate 5 is lifted, the wire rope 4 is tensioned, the wire rope 4 is in a triangular form, and the fixed pulley 3 is subjected to the horizontal tension f of the wire rope 42And a pulling force f obliquely upward3,f2And f3Total force of equal to f1And the steel plate 5, the steel wire rope 4 and the lifting hook body 1 are in a balanced state under the action of gravity of the steel plate 5 and the pulling force of the travelling hook, so that the self-locking function is realized. The heavier the steel plate 5 is, the larger the acting force applied to the steel wire rope 4 is, the larger the self-locking force is, the larger the friction force between the steel plate 5 and the hook body 1 is, and the steel plate 5 is not easy to fall off.
The utility model discloses the highest steel sheet that can once only hoist 30mm thick.
As shown in figure 2, the lifting hook body 1 of the utility model is composed of four parts, namely a connecting part 1-1, a supporting part 1-2, a bending part 1-3 and a supporting arm 1-4, and the lifting hook body 1 is integrally formed, the length of the supporting arm 1-4 is 1.5-1.7 times, preferably 1.6 times, the length of the connecting part 1-1 is greater than that of the supporting part 1-2, the structure increases the strength of the lifting hook body 1, and prevents the breakage of the lifting hook body 1, thereby causing unnecessary injury and loss. The included angle between the supporting part 1-2 and the supporting arm 1-4 is 90 degrees, the included angle between the connecting part 1-1 and the supporting arm 1-4 is 90 degrees, and the supporting part 1-2 and the connecting part 1-1 are positioned on the same side of the supporting arm 1-4. If the angle is too large, the steel plate 5 is likely to slide off in the actual use process.
