Description

Technical Field

[0001] The utility model belongs to the technical field of rod lifting tools, and particularly relates to a round rod lifting tool. Background Art

[0002] During the processes before and after heat treatment, it is often necessary to lift rods to a designated area. Most of the current lifting tools have complex structures, which are not conducive to the operation of workers and have high manufacturing costs; there are also cases where steel cables or slings are used to lift rods, but in the process of transferring the rods, both the steel cables and the slings are prone to sliding towards the middle of the rod, resulting in the imbalance of the rod and even the occurrence of dropping accidents. Therefore, it is necessary to make improvements. Summary of the Utility Model

[0003] To solve the above-mentioned deficiencies of the prior art, the present application provides a round rod lifting tool, which not only has a simple structure, low manufacturing cost, and is easy to operate, but also can be applicable to round rod workpieces of different heights and different diameters.

[0004] To achieve the above purpose, the utility model adopts the following technologies:

[0005] A round rod lifting tool includes a lifting rope, and lifting rings are symmetrically arranged at both ends of the lifting rope. A swing rod is rotatably arranged at the bottom outside the lifting ring, and the axis direction of its rotation is perpendicular to the axis direction of the lifting ring. A blocking portion is arranged on one side of the end of the swing rod facing the axis of the lifting ring;

[0006] An elastic element is arranged at the rotating part of the lifting ring and the swing rod. When the elastic element is in a natural state, the end of the swing rod is inclined towards the axis of the lifting ring;

[0007] A wedge-shaped block is arranged at the bottom inside the lifting ring. The inclined surface of the wedge-shaped block is inclined towards the axis inside the lifting ring, and the upper edge of the inclined surface of the wedge-shaped block fits with the inner wall of the lifting ring.

[0008] The beneficial effect of the utility model lies in that: with the assistance of the wedge-shaped block in the present application, the bottom of the round rod can be jacked up, enabling the round rod to enter the inside of the lifting ring. Continuously moving the lifting ring inward, the round rod contacts the bottom surface inside the lifting ring under the action of gravity, and this causes the swing rod to rotate outward. In this process, the swing rod will always be in contact with the bottom surface of the round rod until the blocking portion abuts against the end surface of the round rod, and then it can cooperate with the lifting equipment for lifting. Such a lifting tool not only has a simple structure and is easy to operate, but also can effectively prevent the lifting ring from sliding towards the middle of the round rod, avoiding the occurrence of rod imbalance and dropping accidents.

[0014] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0015] The embodiment of the present application provides a round rod hoisting tool. As Figure 1 and Figure 2 shown, it includes a suspension rope 1. Sling rings 3 are symmetrically arranged at both ends of the suspension rope 1. A swing rod 4 is rotatably arranged at the bottom outside the sling ring 3, and the axis direction of its rotation is perpendicular to the axis direction of the sling ring 3. A blocking portion 41 is provided on one side of the end of the swing rod 4 facing the axis of the sling ring 3.

[0016] An elastic element 5 is provided at the rotating part of the sling ring 3 and the swing rod 4. When the elastic element 5 is in a natural state, the end of the swing rod 4 is inclined towards the axis of the sling ring 3.

[0017] A wedge-shaped block 6 is provided at the bottom inside the sling ring 3. The inclined surface of the wedge-shaped block 6 is inclined towards the axis inside the sling ring 3, and the upper edge of the inclined surface of the wedge-shaped block 6 fits with the inner wall of the sling ring 3.

[0018] When round rods with different diameters are lifted by the device, they always contact the inner bottom surface of the sling ring 3 under the action of gravity. Therefore, the swing rod 4 is arranged on the bottom surface of the sling ring 3, which can keep in contact with the bottom surfaces of round rods with different diameters, so that the blocking portion 41 abuts against the end surface of the round rod, thereby preventing the sling ring 3 from sliding towards the middle of the round rod.

[0019] During application, first place the sling rings 3 on both sides of the suspension rope 1 at both ends of the round rod respectively, and then move the sling rings 3 inward to jack up both ends of the round rod by using the wedge-shaped block 6.

[0020] Continue to move the sling rings 3 inward. After the round rod is gradually jacked up by the wedge-shaped block 6 and enters the inside of the sling ring 3, the round rod contacts the inner bottom surface of the sling ring 3 under the action of gravity. Then, when the sling ring 3 moves, the round rod contacts the upper surface of the swing rod 4. The swing rod 4 rotates outward under the pressure of the round rod, and the swing rod 4 always fits with the bottom surface of the round rod.

[0021] After that, continue to move the sling ring 3 inward until the round rod is confined between the two sling rings 3 and the two blocking parts 41. At this time, under the action of the elastic element 5, the two swing rods 4 will always remain in a state of being in contact with the bottom surface of the round rod, so that the blocking part 41 will always be in contact with the end face of the round rod. Finally, connect the middle part of the lifting device and the lifting rope 1, and the round rod can be lifted.

[0022] The setting of the above structure is not only easy to operate, but also simple in structure, reducing the manufacturing cost, and can be applied to round rod workpieces of different heights and different diameters, improving the practicability of the device, and can effectively prevent the sling ring 3 from sliding towards the middle of the round rod, avoiding the imbalance of the rod and preventing the occurrence of falling accidents.

[0023] Preferably, as Figure 3 shown, the top surface of the wedge block 6 is an arc surface. The arc surface can well cooperate with the outer wall of the round rod to prevent the round rod from rolling to both sides of the wedge block 6 during the process of the wedge block 6 supporting the round rod.

[0024] Preferably, as Figure 4 shown, the bottom of the wedge block 6 is a plane, and the plane protrudes from the bottom of the sling ring 3. When the lifting tool is placed on the ground, by contacting the ground through the bottom surface of the wedge block 6, the lifting tool can always be kept upright, avoiding the situation that the sling ring 3 rolls on the ground, and facilitating the connection between the lifting tool and the round rod.

[0025] Preferably, as Figure 1 and Figure 4 shown, the elastic element 5 is a spring piece. The setting of the spring piece can not only make the swing rod 4 easily tilt inward, but also bear high pressure and heavy load. Therefore, when lifting, the spring piece can provide sufficient supporting force for the swing rod 4 to keep the swing rod 4 always in contact with the bottom surface of the round rod, so that the blocking part 41 is always at the end face of the round rod, further preventing the lifting tool from sliding towards the middle of the round rod.

[0026] Specifically, as Figure 1 and Figure 2 shown, a hanging ring 2 is provided in the middle of the lifting rope 1. So as to facilitate the connection of the lifting equipment and solidify the middle position of the lifting rope 1, ensure that the distances between the sling rings 3 at both ends of the lifting rope 1 and the middle of the lifting rope 1 are the same, and thus ensure the balance of the round rod during lifting.

[0027] In application, the above is only the preferred embodiment of the present application and is not used to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
