Description

Technical Field

[0001] The utility model relates to the technical field of steel coil processing equipment, in particular to a steel coil hoisting tool. Background Art

[0002] Steel coil, also known as coiled steel, is formed into a coil by hot pressing or cold pressing for the convenience of storage, transportation and processing. Generally, the weight of a steel coil is between 15T and 30T. During transportation and storage, for safety reasons, the steel coil is often laid flat, but it needs to be stood up during processing.

[0003] In the process of standing up the steel coil, one way is for multiple people to work together with the help of the tools at hand, which is labor-intensive and has the risk of endangering personal safety; another way is to use a crane to lift the steel coil through a C-type hook first, and then cooperate with the intervention of workers to keep the steel coil standing when lowering it. Although this can reduce the labor intensity to a certain extent, it still has the risk of endangering personal safety. Utility Model Content

[0004] An embodiment of the present application provides a steel coil lifting tool, which can basically rely on a lifting device, such as a crane, to complete the lifting of the steel coil, so that the steel coil is transformed from a flat state to a standing state. It is easy to use and can effectively reduce labor intensity and reduce the risk of endangering personal safety.

[0005] The embodiment of the present application provides a steel coil hoisting tool, which is U-shaped and includes a short side beam, a long side beam and a connecting beam, wherein the short side beam and the long side beam are respectively vertically connected to the two ends of the connecting beam at the end, and the length of the short side beam is less than the length of the long side beam;

[0006] A hook is hingedly connected to one end of the short side beam away from the connecting beam, so that the hook can rotate in the plane where the steel coil lifting tool is located. A lifting ring is arranged on one side of the connecting beam away from the short side beam and the long side beam, and the lifting ring is close to the short side beam, so that when a crane passes through the lifting ring to lift the steel coil lifting tool, the connecting beam can be kept in a horizontal state;

[0007] When the crane does not lift the hook, the gap between the hook and the long side beam is greater than the single-side thickness of the steel coil. When the crane lifts the steel coil lifting tool through the hook, the inner end of the hook abuts against the outer wall of the steel coil.

[0008] In a possible implementation, the lifting ring and the lifting hook are respectively connected with a lifting rope.

[0009] In a possible implementation manner, a first reinforcing rib plate is provided at a connection position between the connecting beam and the long side beam.

[0010] In a possible implementation, the short side beam, the long side beam, the connecting beam and the first reinforcing rib plate are integrally formed, and the first reinforcing rib plate is L-shaped and is respectively arranged on two symmetrical sides of the connecting beam and the long side beam.

[0011] In a possible implementation, a second reinforcing rib plate is provided at the connection position between the connecting beam and the short side beam, the length direction of the second reinforcing rib plate maintains a 45° angle with the length directions of the connecting beam and the short side beam, and the second reinforcing rib plate is respectively provided on two symmetrical side surfaces of the connecting beam and the short side beam.

[0012] In a possible implementation manner, the widths of the short side cross beam and the long side cross beam are equal, and the length of the long side cross beam is 1.15 to 1.35 times the length of the short side cross beam.

[0013] In a possible implementation, the short side beam is provided with a limiting channel for the hook to rotate, the hook is hinged to the short side beam through a pin shaft, and the pin shaft vertically passes through the limiting channel and is close to the outer end of the limiting channel.

[0014] Beneficial effect: Compared with the prior art, the steel coil lifting tool provided by the present application is provided with a hook in a hinged manner on the short side beam, and a lifting ring is also provided on the outer side of the connecting beam. When the crane lifts the steel coil lifting tool to the vicinity of the steel coil through the lifting ring, the U-shaped opening of the steel coil lifting tool is buckled into the side of the steel coil, and then the crane hook is manually turned to hook the hook on the short side beam. As the crane hook rises, the inner end of the hook on the short side beam gradually abuts against the outer wall of the steel coil, and finally cooperates with the long side beam to fix the steel coil until the steel coil is lifted to a standing state. It is easy to use, with low manual intervention, and can effectively reduce labor intensity and reduce the risk of endangering personal safety.

[0015] These and other purposes, features and advantages of the present invention are fully reflected in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0018] Those skilled in the art should understand that, in the disclosure of the specification, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0019] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0020] refer to Figure 1 The embodiment of the present application provides a steel coil hoisting tool. The steel coil hoisting tool is U-shaped, including a short side beam 10, a long side beam 20 and a connecting beam 30, wherein the short side beam 10 and the long side beam 20 are respectively connected to the two ends of the connecting beam 30 vertically through the end, and the length of the short side beam 10 is less than the length of the long side beam 20;

[0021] A hook 40 is hingedly connected to one end of the short side beam 10 away from the connecting beam 30, so that the hook 40 can rotate in the plane where the steel coil lifting tool is located. At the same time, a lifting ring 31 is provided on one side of the connecting beam 30 away from the short side beam 10 and the long side beam 20, and the lifting ring 31 is close to the short side beam 10, so that when a driving vehicle passes through the lifting ring 31 to lift the steel coil lifting tool, the connecting beam 30 can be kept in a horizontal state, which is convenient for the driving vehicle to lift and transfer the steel coil lifting tool;

[0022] In addition, when the crane does not lift the hook 40, the gap between the hook 40 and the long side beam 20 is greater than the single-side thickness of the steel coil, so that the U-shaped opening 101 of the steel coil lifting tool can be inserted into the side of the steel coil. In addition, when the crane lifts the steel coil lifting tool through the hook 40, the inner end of the hook 40 abuts against the outer wall of the steel coil, and as the steel coil lifting tool rises, the force applied by the hook to the steel coil increases, and finally the hook 40 firmly abuts against the outer edge of the steel coil.

[0023] During the work process, steel coils are generally placed in one place and are not mixed with steel coil lifting tools. The steel coil lifting tool is first lifted by the crane through the lifting ring 31, and the steel coil lifting tool is transferred to the steel coil. Then, the crane hook is manually untied and the crane hook is turned to the hook 40 on the short side beam 10. Because the distance between the hook 40 and the long side beam 20 is greater than the single-side thickness of the steel coil when the crane has not lifted the hook 40, the U-shaped opening 101 of the steel coil lifting tool can be manually cooperated with the crane to be inserted into the side of the steel coil. Then, the staff member moves away from the steel coil, and the crane hook slowly pulls up the hook 40 of the short side beam 10. As the pulling height increases, the inner end of the hook 40 gradually presses against the steel coil, and finally cooperates with the long side beam 20 to firmly fix the steel coil until the steel coil is straightened and stands up. It is easy to use, and only manual labor is involved in the process of transferring the crane hook and cooperating with the crane to insert the U-shaped opening 101 into the side of the steel coil. The manual participation is low, the labor intensity is small, and the risk of endangering personal safety can be effectively reduced.

[0024] In one embodiment, the lifting ring 31 and the lifting hook 40 are respectively connected with lifting ropes to facilitate quick hooking of the crane hook and improve work efficiency.

[0025] In one embodiment, a first reinforcing rib plate 61 is provided at the connection position between the connecting beam 30 and the long side beam 20 to enhance the connection strength between the connecting beam 30 and the long side beam 20, thereby extending the service life of the steel coil lifting tool.

[0026] Further preferably, the short side beam 10, the long side beam 20, the connecting beam 30 and the first reinforcing rib plate 61 are integrally formed, which is convenient for rapid manufacturing and forming, and the structural connection relationship is tight. In addition, the first reinforcing rib plate 61 is L-shaped and is respectively arranged on two symmetrical sides of the connecting beam 30 and the long side beam 20, so that it can extend a certain length along the length direction of the connecting beam 30 and the long side beam 20, respectively, and can further improve the connection strength between the connecting beam 30 and the long side beam 20.

[0027] In one embodiment, a second reinforcing rib plate 62 is provided at the connection position between the connecting beam 30 and the short side beam 10, so as to improve the structural connection strength between the connecting beam 30 and the short side beam 10. The length direction of the second reinforcing rib plate 62 is respectively at an angle of 45° with the length direction of the connecting beam and the short side beam, and the second reinforcing rib plate 62 is respectively provided on two symmetrical sides of the connecting beam 30 and the short side beam 10.

[0028] In one embodiment, the widths of the short side beam 10 and the long side beam 20 are equal, and the length of the long side beam 20 is 1.15 to 1.35 times the length of the short side beam 10. For example, when the length of the long side beam 20 is 1000 mm, the length of the short side beam 10 is 800 mm. In this way, when the steel coil is suspended and supported to a standing state, the steel coil lifting tool can be well balanced. At the same time, the longer long side beam 20 passes through the center hole of the steel coil and extends to the other side, which can ensure the stability of the steel coil lifting tool in clamping the steel coil. The steel coil is not easy to separate from the steel coil lifting tool, and the operation is safer.

[0029] In one embodiment, the short side beam 10 is provided with a limiting channel for the hook 40 to rotate, and the hook 40 is hinged to the short side beam 10 through a pin 41, and the pin 41 vertically penetrates the limiting channel and is close to the outer end of the limiting channel, that is, the end away from the connecting beam 30. It should be noted that the end of the short side beam 10 away from the connecting beam 30 is closed, and the limiting channel is only close to the outer end of the short side beam 10. During the rotation of the hook 40, the hook 40 will not rotate to the outside of the short side beam 10. On the one hand, it is safer to use, and on the other hand, the hook 40 can be restricted in the limiting channel, and the rotation range is limited, so it can be put into work more quickly, which can improve work efficiency.

[0030] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
