Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0025] Please refer to the attached Figure 1 To Attachment Figure 3 The utility model describes a hanging hook fixing device.

[0026] In the offshore engineering steel structure processing workshop, there are a lot of thin and large steel plate hoisting operations. During the hoisting process, thin plates are more flexible, and the force concentration around the hoisting point is likely to occur, which will cause excessive deformation in the middle and the hook 8 to slide toward the middle, resulting in the instability of the plate hoisting, causing on-site hoisting safety risks and seriously affecting on-site construction operations. Therefore, it is urgent to design a hoisting hook fixing device to solve the above-mentioned problems.

[0027] like Figure 1 As shown, when the steel plate is hoisted, four hooks 8 are used for hoisting, and there are two hooks 8 on each side of the steel plate. The hooks 8 are hung on the steel plate for hoisting. During the hoisting process, the thin plate is more flexible, and force concentration is easily generated around the hoisting point. Excessive deformation in the middle and sliding of the hooks 8 to the middle will occur, resulting in instability of the plate hoisting, causing safety risks for on-site hoisting, and seriously affecting on-site construction operations.

[0028] like Figure 2 As shown, the hoisting hook fixing device in the utility model includes a U-shaped fixing part 1, a partition plate 2 is vertically arranged on the U-shaped fixing part 1, a tightening nut 3 is arranged at one end of the U-shaped fixing part 1, a tightening screw 4 is threadedly arranged inside the tightening nut 3, and a to-be-hoisted part 9 is clamped between the end of the tightening screw 4 away from the tightening nut 3 and the other end of the U-shaped fixing part 1, and the end of the partition plate 2 away from the U-shaped fixing part 1 abuts against the hook 8 to limit the hook 8 on the to-be-hoisted part 9. In this embodiment, the to-be-hoisted part 9 is a steel plate with a relatively thin thickness and a relatively large size. The U-shaped fixing part 1 is made of steel, and in order to prevent rust, anti-rust paint is applied to the outside of the U-shaped fixing part 1.

[0029] A partition plate 2 is vertically arranged on the U-shaped fixing piece 1, a tightening nut 3 is arranged at one end of the U-shaped fixing piece 1, a tightening screw 4 is threadedly arranged inside the tightening nut 3, the tightening screw 4 clamps the part to be hoisted 9 between the end away from the tightening nut 3 and the other end of the U-shaped fixing piece 1, and the end of the partition plate 2 away from the U-shaped fixing piece 1 is in contact with the hook 8. During the process of using the hook 8 to hoist the part to be hoisted 9, the hoisting hook 8 is fixed, which can effectively solve the problems of plate hoisting deformation and hook 8 slippage, enhance the safety of on-site hoisting, and has a simple structure, easy use, light weight, easy to carry, high frequency of use, long service life, and improves the efficiency of hook 8 hoisting.

[0030] Further, if Figure 2 As shown, the U-shaped fixing member 1 includes a first connecting plate 11, a second connecting plate 12 and an arc-shaped transition plate 13. The first connecting plate 11 and the second connecting plate 12 are respectively arranged at the two ends of the arc-shaped transition plate 13, and the first connecting plate 11 and the second connecting plate 12 are arranged in parallel. The first connecting plate 11 and the second connecting plate 12 are clamped and fixed on the part to be hoisted 9, and the end of the partition plate 2 away from the U-shaped fixing member 1 is in contact with the hook 8. Since the U-shaped fixing member 1 is fixed on the part to be hoisted 9, the movement of the hook 8 relative to the part to be hoisted 9 is restricted, thereby enhancing the safety of on-site hoisting. In addition, the structure is simple, easy to use, light in weight, easy to carry, high in frequency of use, and long in service life, thereby improving the efficiency of the hoisting of the hook 8. At the same time, since the hook 8 is fixed relative to the part to be hoisted 9, the part to be hoisted 9 will not be deformed during the hoisting process, thereby ensuring the smooth progress of the hoisting. In this embodiment, the length of the first connecting plate 11 is less than the length of the second connecting plate 12, and the first connecting plate 11 is welded and fixed to the partition plate 2.

[0031] Further, if Figure 2 As shown, in order to ensure that the U-shaped fixing member 1 will not be deformed when it is subjected to the squeezing force of the hook 8 or when the U-shaped fixing member 1 clamps the hoisting member 9 during use, the hoisting hook fixing device in the utility model also includes a reinforcing plate 5, one end of the reinforcing plate 5 is connected to the first connecting plate 11, and the other end of the reinforcing plate 5 is connected to the second connecting plate 12. In this embodiment, one end of the reinforcing plate 5 is arranged at one end of the first connecting plate 11 close to the arc-shaped transition plate 13, and the other end of the reinforcing plate 5 is arranged at one end of the second connecting plate 12 close to the arc-shaped transition plate 13. In other embodiments, multiple reinforcing plates 5 can be arranged between the first connecting plate 11 and the second connecting plate 12, or the width of the reinforcing plate 5 can be increased to improve the overall strength.

[0032] Further, if Figure 2 and Figure 3As shown, the spacer plate 2 is vertically arranged on the first connecting plate 11, and one end of the spacer plate 2 away from the first connecting plate 11 is in contact with the hook 8. When hoisting the part 9 to be hoisted, first fix the U-shaped fixing part 1 on the part 9 to be hoisted, and fix two U-shaped fixing parts 1 on the sides of the part 9 in the length direction. A hook 8 is arranged on each U-shaped fixing part 1, and the hook 8 is arranged on the outside of the U-shaped fixing part 1, and the spacer plate 2 on each U-shaped fixing part 1 is in contact with a hook 8. After the installation is completed, the position sequence of the U-shaped fixing part 1 and the hook 8 is hook 8, U-shaped fixing part 1, U-shaped fixing part 1 and hook 8.

[0033] Further, if Figure 2 As shown, the tightening nut 3 is arranged at one end of the first connecting plate 11 away from the arc-shaped transition plate 13, and the tightening screw 4 is screwed into the tightening nut 3. The end of the tightening screw 4 away from the tightening nut 3 and the second connecting plate 12 clamp the part to be hoisted 9. Through the cooperation of the tightening screw 4 and the tightening nut 3, the clamping distance between the tightening screw 4 and the second connecting plate 12 can be adjusted to adapt to steel plates of different thicknesses. In this embodiment, the length of the tightening screw 4 is equal to the distance between the first connecting plate 11 and the second connecting plate 12. In this embodiment, the tightening nut 3 and the first connecting plate 11 are welded and fixed.

[0034] Further, if Figure 2 As shown, the lifting hook fixing device in the utility model also includes a bolt handle 6, and a handle nut 7 is also provided at one end of the tightening screw 4 away from the second connecting plate 12. The bolt handle 6 is threaded inside the handle nut 7, and the distance between the tightening screw 4 and the second connecting plate 12 is adjusted by the bolt handle 6. By providing the bolt handle 6, when in use, the position of the bolt handle 6 on the handle nut 7 is adjusted, which is convenient for saving effort when rotating the bolt handle 6 relative to the U-shaped fixing member 1, and is easy to adjust. The rotation of the bolt handle 6 relative to the U-shaped fixing member 1 can drive the tightening screw 4 to rotate relative to the tightening nut 3, thereby adjusting the distance between the tightening screw 4 and the second connecting plate 12, and thereby achieving the clamping of the hoisting member 9 to be clamped.

[0035] Further, if Figure 2 and Figure 3As shown, when the hoisting part 9 is to be hoisted, the tightening screw 4 is adjusted so that the distance between the tightening screw 4 and the second connecting plate 12 becomes larger, so as to facilitate clamping on the hoisting part 9. After clamping, the tightening screw 4 is adjusted so that the tightening screw 4 is tightened in the direction of the second connecting plate 12, and the U-shaped fixing part 1 is clamped on the hoisting part 9. A hook 8 is provided at each U-shaped fixing part 1, and the hook 8 is provided on the outside of the U-shaped fixing part 1. At the same time, the partition plate 2 on the U-shaped fixing part 1 is abutted against a hook 8. Finally, the hook 8 is connected to the hoisting equipment through the hoisting rope 10 to realize the hoisting of the hoisting part 9. By fixing and clamping the U-shaped fixing part 1 on the hoisting part 9, the position of the hook 8 can be limited, which can effectively solve the problem of plate hoisting deformation and hook 8 slippage, enhance the safety of on-site hoisting, and has a simple structure, convenient use, light weight, easy to carry, high frequency of use, long service life, and improves the efficiency of hook hoisting.
