[0002] The existing molten steel lifting hook is a sheep's horn hook, and its outer dimension is almost an equilateral triangle (as Figure 1 shown), with large size, serious inclination after loading, poor universality, and a large transportation area occupied during movement. It can only operate in places with a large space and cannot operate in narrow spaces. Therefore, in order to reduce the transportation area, the structure of the molten steel lifting device needs to be optimized. Summary of the Utility Model

[0021] The present utility model provides an anchor hook for a metallurgical crane, and its beneficial effects are as follows:
[0022] The two hook parts of the anchor hook for a metallurgical crane are used as spares for each other, and one of them is selected for use during use. Compared with a single-hook structure, the service life is doubled, and the occupied space is reduced through a compact layout.

[0023] Other features and advantages of the present utility model will be described in detail in the following specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS
[0024] By describing the exemplary embodiments of the present utility model in more detail in conjunction with the drawings, the above-mentioned and other objects, features, and advantages of the present utility model will become more obvious.

[0028] 1. Hook rod; 2. Hook bending part; 3. Return hook part; 4. Hook connector. Specific embodiments
[0029] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0030] As Figure 2 shown, an anchor hook for a metallurgical crane includes:
[0031] A hook rod 1, and a connecting part is provided at the upper end of the hook rod 1;
[0032] Two hook parts, which are symmetrically arranged at the lower end of the hook rod 1. The hook bending part 2 of the hook part is a semi-circular structure. One end of the hook bending part 2 is tangent to the side wall of the hook rod 1, and a return hook part 3 is provided at the other end of the hook bending part 2. The return hook part 3, the hook bending part 2 and the hook rod 1 form a U-shaped or C-shaped structure.
[0033] Specifically, the two hook parts are used alternately. When in use, one of them is selected. Compared with a single-hook structure, the service life is doubled. And through a compact layout, the occupied space is reduced. While adapting to use in a narrow space, the swaying amplitude during movement is also reduced and the movement safety range is reduced, increasing the safety space in the plant area and reducing the interference risk. At the same time, the return hook part 3 reduces the risk of slipping off and is suitable for use in an inclined state.
[0034] In this embodiment, the lower ends of the two hook parts are flush with the lower end of the hook rod 1 to form a flat bottom. The outer arc part of the return hook part 3, the outer arc part of the hook bending part 2 and the flat bottom are smoothly transitioned. A weight reduction hole is provided in the flat bottom, and a counterweight rod is provided in the weight reduction hole.
[0035] Specifically, the flat bottom is used for weight adjustment to balance the center of gravity and facilitate the anchor hook to maintain a standing posture and a state perpendicular to the ground when unloaded. When the anchor hook is in use, only one side is stressed. The balance center of gravity can be adjusted by the cooperation of the weight reduction hole and the counterweight rod, and then the inclination state of the anchor hook can be adjusted, which is beneficial to reducing the swaying of the anchor hook and the angle of the molten steel ladle being hooked.
[0036] In this embodiment, the tail end of the return hook part 3 is connected to the hook part, and the tip of the return hook part 3 is close to the hook rod 1.
[0037] Specifically, the return hook part 3 approaches the hook rod 1 to prevent the molten steel ladle from unhooking.
[0038] In this embodiment, the vertical projection of the return hook part 3 is connected to or partially overlaps with the vertical projection of the hook bending part 2.
[0039] Specifically, the back-hooking part 3 is tangent to the hooked part 2 or partially extends beyond the tangent line towards the hook rod 1, preventing the back-hooking part 3 and the hook rod 1 from forming a flared structure.
[0040] In this embodiment, the vertical projection of the tip of the back-hooking part 3 is within the vertical projection of the tail end of the back-hooking part 3.
[0041] Specifically, prevent the back-hooking part 3 from extending outwards to affect hooking and unhooking.
[0042] In this embodiment, the bearing capacity of the hook part is less than that of the hook rod 1.
[0043] Specifically, the bearing capacity of the hook part is less than that of the hook rod 1. When overloaded, only the stressed hook part is damaged, and the hook rod 1 and the remaining hook parts can still be used temporarily for emergency after weight reduction, avoiding having no hook available.
[0044] In this embodiment, the hooked parts of the two hook parts are respectively rounded and not rounded at the corners.
[0045] Specifically, the rounded corners are suitable for using ropes and chains, and the non-rounded corners are used to increase the contact area for using molten steel ladles. The molten steel ladle is provided with a hook shaft and is connected to the non-rounded hook part through the hook shaft for use, increasing the contact area and avoiding shaking affected by the rounded corners at the same time, improving stability.
[0046] Furthermore, according to needs, both hook parts can be rounded or not rounded at the corners.
[0047] In this embodiment, the connecting part is a connecting hole, and the axis of the connecting hole is parallel to the axis of the hooked part 2.
[0048] Specifically, the axis of the connecting hole is parallel to the axis of the hooked part 2, so that the anchor hook can only swing around the axis of the connecting hole, and the molten steel ladle can only swing around the axis of the hook, making the molten steel ladle also swing in the same plane, reducing the swinging freedom and space of the molten steel ladle.
[0049] In this embodiment, the connecting hole is connected with a hook connector 4, and the hook connector 4 is used to connect the hook of the crane. The hook connector 4 includes:
[0050] Two connecting plates, which are arranged in parallel at intervals;
[0051] A first rotating shaft, which is rotatably connected in the connecting hole, and both ends of the first rotating shaft are respectively connected to one end of the two connecting plates;
[0052] A second rotating shaft, and both ends of the second rotating shaft are respectively connected to the other end of the two connecting plates.
[0053] Specifically, the hook connector 4 is adapted to the hook of the crane, and at the same time increases the rotational freedom and reduces the swinging amplitude.
[0054] The present utility model also provides a metallurgical crane, comprising:
[0055] The above-mentioned anchor hook for metallurgical crane.
[0056] When the anchor hook for metallurgical crane in this embodiment is in use, taking the transfer of molten steel ladle as an example:
[0057] Connect the hook of the crane through the coupling 4. Neither of the two hook parts has a chamfer. First, select one hook part to connect the molten steel ladle. However, when this hook part is worn, it is replaced with the other hook part for use, so that the service life of the anchor hook is increased and the occupied space is reduced.
[0058] The embodiments of the present utility model have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
