[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

[0035] It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of the embodiments of this application.

[0036] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0037] Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0038] In the application scenario, the mill's blower is located above the plant's own pipelines, making it impossible to directly lift the blower using a bridge crane. Therefore, in conjunction with... Figure 1 and Figure 2As shown, this utility model discloses a hoisting device for a reversible rolling mill fan 20, comprising: a hoist 10, one end of which is provided with a lifting end 110 and the other end with a counterweight end 120; a rolling mill fan 20, which is disposed at the lifting end 110; a counterweight mechanism 30, which is disposed at the counterweight end 120; and a bridge crane, which suspends the hoist 10 by means of a wire rope 40.

[0039] Specifically, the mill fan 20 is first hung on the lifting end 110 of the hanger 10, and then the counterweight mechanism 30 of the counterweight end 120 is used to balance the hanger 10 so that it does not tilt to one side. At this time, the bridge crane uses the wire rope 40 to lift the hanger 10, and the mill fan 20 can be slowly moved out.

[0040] Compared with the prior art, this application innovatively uses a bridge crane to lift the hanger 10. The lifting end 110 of the hanger 10 lifts the rolling mill fan 20, and the counterweight end 120 achieves counterweight balance of the hanger 10 through the counterweight mechanism 30, thereby hoisting the fan to the designated position, reducing the labor intensity of workers and improving work efficiency.

[0041] In this embodiment, the lifting end 110 is connected to the rolling mill fan 20 via a lifting rope 50, which avoids the lifting end 110 directly acting on the rolling mill fan 20, and also increases the distance using the lifting rope 50.

[0042] In this embodiment, the mill fan 20 is provided with a lifting ring 210, and one end of the lifting rope 50 is suspended at the lifting ring 210 so that the lifting rope 50 passes through the lifting ring 210 in preparation for lifting the mill fan 20.

[0043] In this embodiment, the lifting end 110 is provided with a stabilizing bolt 111 and a positioning plate 112, and a lifting area is provided between the stabilizing bolt 111 and the positioning plate 112; the other end of the lifting rope 50 is provided with a lifting rope loop 510, which is hung in the lifting area and is confined thereto to prevent the lifting rope 50 and the rolling mill fan 20 from swinging during the lifting process. Furthermore, after the stabilizing bolt is unscrewed, the lifting rope loop 510 can be easily removed from the lifting area.

[0044] In this embodiment, the counterweight mechanism 30 includes a counterweight frame 310, multiple counterweight blocks 320, and a connecting structure. The counterweight frame 310 is disposed at the counterweight end 120. One or more counterweight blocks 320 are connected to the counterweight frame 310 through the connecting structure. By increasing or decreasing the number of counterweight blocks 320, different weights of rolling mill fans 20 can be matched. Each counterweight block 320 weighs 50 kg, and there are a total of 10 counterweight blocks 320. The specific number of counterweight blocks 320 can be selected according to the weight of the rolling mill fan 20.

[0045] Furthermore, the counterweight frame 310 is provided with fixing holes; the counterweight block 320 is provided with positioning holes; the connecting structure includes connecting bolts 331 and fixing nuts 332. The connecting bolts 331 are sequentially passed through the positioning holes and the fixing holes and then tightened with the fixing nuts 332. After determining the number of counterweight blocks 320, the connecting bolts 331 are sequentially passed through the positioning holes of the counterweight blocks 320 from bottom to top, then through the fixing holes, and finally tightened with the fixing nuts 332 to install the counterweight blocks 320 onto the counterweight frame 310.

[0046] In this embodiment, the counterweight mechanism 30 further includes an adjusting lever 340 and a fixing block 350. The fixing block 350 is fixedly disposed on the lower side of the hanger 10. The adjusting lever 340 is disposed along the length direction of the hanger 10, and the threaded section of the adjusting lever 340 is threadedly connected to the fixing block 350. One end of the adjusting lever 340 is provided with an adjusting handle 341, and the other end of the adjusting lever 340 is connected to the counterweight frame 310 through a bearing seat. The counterweight frame 310 slides along the length direction of the hanger 10 at the counterweight end 120 under the rotation of the adjusting lever 340. When the hanger 10 is unbalanced or the weight is mismatched, the adjusting lever 340 can be manually rotated by adjusting the adjusting handle 341 to match the weight of the counterweight frame 310 and the counterweight block 320 with the weight of the rolling mill fan 20, thereby achieving the balance of the hanger 10. The threaded section is threadedly connected to the fixing block 350, and after adjustment, it can fix the position of the adjusting lever 340 to prevent accidental changes.

[0047] It should be noted that the adjusting handle 341 is an adjusting rod, which is movably inserted through one end of the adjusting lever 340 to allow rotation of the adjusting lever 340. Furthermore, the other end of the adjusting lever 340 is connected to the counterweight frame 310 via a bearing seat, ensuring that the counterweight frame 310 only slides along the length of the hanger 10 under the action of the adjusting lever 340, and does not rotate.

[0048] In this embodiment, the counterweight frame 310 is slidably connected to the hanger 10 via pulleys 360, which reduces the friction when the counterweight frame 310 slides and facilitates adjustment.

[0049] In this embodiment, a first limiting plate 101 and a second limiting plate 102 are provided at the counterweight end 120. The first limiting plate 101 and the second limiting plate 102 are distributed along the length direction of the hanger 10, and a sliding area is formed between the first limiting plate 101 and the second limiting plate 102. The pulley 360 is restricted to slide within the sliding area to prevent the counterweight frame 310 from detaching from the hanger 10.

[0050] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
