Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a steel bar cage hanger. Background Art

[0002] During the construction process, due to the space limitation of the construction site, the steel cage cannot be manufactured and processed on the construction site. Instead, a special steel processing site needs to be set up near the construction site. After the steel cage is manufactured and processed at the steel processing site, it is hoisted to the construction site. At present, the steel cage is hoisted with traditional lifting hooks. During the hoisting process, the steel cage cannot remain horizontal and is prone to shaking or bumping, which may cause the steel cage to fall apart or deform easily. In addition, the traditional hooks do not have anti-detachment measures, and there is a risk of the steel cage being unhooked during the hoisting process. Utility Model Content

[0003] The main purpose of the utility model is to provide a steel cage hanger, which can effectively solve the problems in the background technology.

[0005] A steel cage hanger comprises a shoulder pole beam, two first slings are symmetrically arranged on both sides of the top of the shoulder pole beam, one end of the two first slings is fixedly connected to the shoulder pole beam, and the other end is used to be fixedly connected to a lifting machinery, at least three second slings are fixedly connected to the bottom of the shoulder pole beam, and the bottoms of the second slings are fixedly connected to anti-slip hooks, the directions of the anti-slip hooks are staggered and opposite, the anti-slip hooks are U-shaped structures, one end is fixedly connected to the second slings, and the other end is provided with a notch, two protrusions are oppositely arranged on the inner walls on both sides of the bottom of the notch, the side wall of one protrusion is fixedly connected to a first card, and the side wall of the other protrusion is provided with a second card and a reset spring, the second card is located below the first card and is rotatably connected to the protrusion, one end of the reset spring is fixedly connected to the second card, and the other end is fixedly connected to the protrusion.

[0006] Optionally, the two protrusions and the bottom of the notch are combined to form a fixing groove, and an anti-slip pad is provided on the inner wall of the fixing groove.

[0007] Optionally, a tying hole is provided at one end of the anti-drop hook for fixed connection with the second sling.

[0008] Optionally, the shoulder pole beam is made of Q235 steel pipe with a wall thickness of not less than 3 mm.

[0009] Optionally, the first sling and the second sling are both steel wire ropes.

[0010] The utility model provides a steel cage hanger, which has the following beneficial effects:

[0011] 1. The shoulder beam is always in a horizontal state during the lifting process, so the steel cage also always remains in a horizontal state during the lifting process, and is not prone to shaking and bumping, thus avoiding the steel cage from falling apart or deforming.

[0012] 2. The reinforcement ring of the steel cage presses against the second card and squeezes it, the second card rotates inward, the reset spring is compressed, and the reinforcement ring of the steel cage can be easily inserted into the fixed groove, and then the second card is reset under the action of the reset spring. During the lifting process of the steel cage, the first card limits the second card, so that the second card cannot rotate outward at all times, so that the reinforcement ring of the steel cage is always stuck in the fixed groove to prevent the steel cage from being unhooked.

[0022] Example, see Figure 1-4 , a steel cage hanger, comprising a shoulder pole beam 1, two first slings 2 are symmetrically arranged on both sides of the top of the shoulder pole beam 1, one end of the two first slings 2 is fixedly connected to the shoulder pole beam 1, and the other end is used to be fixedly connected to a lifting machinery 100, at least three second slings 3 are fixedly connected to the bottom of the shoulder pole beam 1, and the bottoms of the second slings 3 are fixedly connected with anti-slip hooks 4, and the anti-slip hooks 4 are staggered and opposite in orientation, and the anti-slip hooks 4 are U-shaped structures, one end of which is fixedly connected to the second slings 3, and the other end is provided with a notch 41, and two protrusions 42 are relatively arranged on the inner walls on both sides of the bottom of the notch 41, a first card 43 is fixedly connected to the side wall of one protrusion 42, and a second card 44 and a reset spring 45 are arranged on the side wall of the other protrusion 42, the second card 44 is located below the first card 43, and is rotatably connected to the protrusion 42, and one end of the reset spring 45 is fixedly connected to the second card 44, and the other end is fixedly connected to the protrusion 42.

[0023] In a specific embodiment, the two protrusions 42 and the bottom of the notch 41 are combined to form a fixing groove 46 , and an anti-slip pad 47 is provided on the inner wall of the fixing groove 46 .

[0024] In a specific embodiment, a tying hole 48 is provided at one end of the anti-drop hook 4 for fixed connection with the second sling 3 .

[0025] In a specific implementation manner, the shoulder beam 1 is made of Q235 steel pipe with a wall thickness of not less than 3 mm.

[0026] In a specific embodiment, the first sling 2 and the second sling 3 are both steel wire ropes.

[0027] When lifting the steel cage 200, the two first slings 2 are fixedly connected to the lifting machinery 100, that is, fixedly connected to the hook of the crane. The two first slings 2 and the shoulder pole beam 1 form an isosceles triangle structure, and then the steel cage 200 is hooked by the anti-drop hook 4 for lifting. The shoulder pole beam 1 is always in a horizontal state during the lifting process, so that the steel cage 200 also always maintains a horizontal state during the lifting process, is not easy to shake and bump, and avoids the steel cage 200 from falling apart or deforming.

[0028] There are at least three anti-drop hooks 4, which are staggered and opposite in direction and arranged on both sides of the steel cage 200.

During the lifting process of the steel cage 200, the first card 43 limits the second card 44, so that the second card 44 cannot rotate outward at all times, so that the reinforcement ring 201 of the steel cage 200 is always stuck in the fixing groove 46 to prevent the steel cage 200 from being unhooked. The anti-drop hooks 4 are arranged on both sides of the steel cage 200 and connected to the steel cage 200, so that the force points of the steel cage 200 are staggered on both sides of the steel cage 200, which can also prevent the steel cage 200 itself from being deformed.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
