Description

Technical Field

[0001] This utility model relates to a hoisting device, specifically a hoisting device for air knives and side baffles, which is particularly suitable for hoisting air knives and side baffles on continuous hot-dip galvanizing units for galvanized sheet and strip in the steel industry. Background Technology

[0002] Since the air knife and side baffle are key components in galvanizing units, their role in the galvanizing process is crucial, directly affecting the surface quality of the galvanized sheet and strip and production efficiency. Traditional hoisting methods often suffer from complex operation and insufficient stability, which not only affects production efficiency but may also adversely impact the quality of the galvanized sheet and strip. Therefore, developing a device capable of efficiently and stably hoisting the air knife and side baffle is of paramount importance. This invention aims to solve this technical challenge by providing a novel solution for hoisting the air knife and side baffle in galvanizing units through a scientifically designed and rationally structured structure.

[0003] The air knife and side baffle equipment of the galvanizing unit were originally hoisted directly to the lifting points using steel wire ropes, and then attached to the overhead crane hook for transport. This method has many problems and safety hazards. During hoisting, the air knife and side baffle are subjected to axial and radial forces. Long-term hoisting will cause slight deformation of the air knife and side baffle frame, thus affecting the overall accuracy of the equipment and causing defects in the surface quality and coating control of the galvanized products. At the same time, the equipment lacks stability during hoisting, and is prone to swaying, affecting the positioning accuracy of the air knife and side baffle. Furthermore, the traditional hoisting method is cumbersome, requiring multiple manual adjustments and confirmations by personnel, which not only increases operational complexity but also reduces work efficiency. Additionally, due to the high temperature and corrosive conditions in the zinc pot area of ​​the galvanizing unit, the traditional hoisting method also poses certain safety risks. Therefore, how to design a hoisting device for air knives and side baffles of galvanizing units that can ensure hoisting stability, reduce operational complexity, and improve safety and work efficiency has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a hoisting device for air knives and side baffles in galvanizing units, which solves the problems of reduced equipment precision, high operational complexity, and insufficient safety caused by the original hoisting methods for air knives and side baffles. This hoisting device, through its innovative structural design, achieves stable hoisting of air knives and side baffles, effectively improving the production efficiency and safety of galvanizing units, reducing the labor intensity of operators, and demonstrating significant technological advancement and practical value.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hoisting device for an air knife and side baffle of a galvanizing unit is characterized by comprising a base hanger and a balance hanger beam. The base hanger has symmetrically arranged lifting lugs at both ends of its crossbeams, and multiple lifting holes are evenly arranged on its longitudinal beams. Lifting rods are threadedly connected to the lifting holes, and connectors are fixed to the ends of the lifting rods. The balance hanger beam has multiple evenly arranged balance lifting holes, and two balance hooks are detachably connected to each balance lifting hole. The two balance hooks are located at both ends of the balance hanger beam. The balance hooks at both ends of the balance hanger beam are connected to two lifting lugs on a single crossbeam of the same side of the grid-shaped base hanger via slings.

[0007] The upper end of the connector is provided with a connecting hole, through which it is connected to the hanger rod; the lower end of the connector is provided with a C-shaped bayonet, and an anti-detachment pin is inserted into the C-shaped bayonet.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] After the air knife and side baffle hoisting device for this galvanizing unit is applied, the operators hang the device on the overhead crane hook and hoist it to the air knife placement position. Based on the air knife size, the corresponding lifting rods on the foundation hanger are attached to the hanging points on both sides of the air knife via connectors. Then, using the air knife hoisting position as a reference, the corresponding lifting rods on the foundation hanger are attached to the side baffle hanging points via connectors according to the side baffle installation dimensions. The air knife and side baffle are then hoisted and assembled simultaneously. The design of this air knife and side baffle hoisting device is suitable for galvanizing units of different specifications and sizes. It ensures that the air knife and side baffle are only subjected to vertical forces during hoisting, thus avoiding the deformation problems caused by axial and radial forces in traditional hoisting methods and guaranteeing the overall accuracy of the air knife and side baffle equipment. Meanwhile, the lifting device is also equipped with precision connectors and anti-detachment pins, ensuring accurate positioning and stable connection during the lifting process, effectively avoiding problems such as swaying and inaccurate positioning that may occur in traditional lifting methods. Furthermore, this lifting device not only simplifies the lifting process but also significantly improves stability and safety during lifting. Attached Figure Description

[0015] The present invention will be further explained below with reference to the accompanying drawings.

[0016] like Figure 1-3 As shown, a hoisting device for an air knife and side baffle of a galvanizing unit includes a base hanger 1 and a balance hanger beam 2. The two ends of the crossbeam of the base hanger 1 are symmetrically provided with lifting lugs 11, and multiple lifting holes 12 are evenly provided on the longitudinal beam. The lifting holes 12 are connected to the lifting rods 13 by threads, and the ends of the lifting rods 13 are fixedly connected to the connectors 3. Multiple balance lifting holes 21 are evenly provided on the balance hanger beam 2. Two balance hooks 22 are detachably connected to the balance lifting holes 21. The two balance hooks 22 are respectively located at both ends of the balance hanger beam 2. The balance hooks 22 at both ends of the balance hanger beam 2 are connected to the two lifting lugs 11 on the single crossbeam of the grid-shaped base hanger 1 on the same side by slings.

[0017] like Figure 4 As shown, the upper end of the connector 3 is provided with a connecting hole 31, which is connected to the rod 13 pin through the connecting hole; the lower end of the connector 3 is provided with a C-shaped bayonet 32, and an anti-detachment pin 33 is inserted into the C-shaped bayonet 32.

[0018] In use, first connect the balance hooks 22 at both ends of the balance beam 2 to the two lifting lugs 11 on the single crossbeam of the foundation hanger 1 on the same side using slings, so that the foundation hanger 1 and the balance beam 2 are connected to form a combined lifting device. The position of the balance hooks 22 can be adjusted according to the actual site conditions to ensure balanced lifting and prevent tilting. Then, according to the installation position and size of the air knife, select the lifting hole 12 in the middle of the foundation hanger 1 and install the lifting rod 13 in the lifting hole 12. The end of the lifting rod 13 is fixed to the connector 3. After connecting the lifting point on the air knife to the foundation hanger 1 through the connector 3, select the lifting holes 12 and lifting rods 13 on both sides of the foundation hanger 1 according to the relative installation position of the air knife and the side baffles on both sides. Repeat the above steps and connect the lifting points of the side baffles through the connector 3. After all the lifting points are firmly connected and checked to be correct, lift the device at a uniform speed with a crane and monitor the horizontal status of the lifting device in real time.

[0019] This galvanizing unit's air knife and side baffle hoisting device boasts high adaptability and flexibility, allowing adjustment to accommodate air knives and side baffles of varying specifications and sizes to meet diverse hoisting needs. Through precise calculations and rational design, the coordination and stability of all components are ensured, guaranteeing that the air knives and side baffles are subjected only to vertical forces during hoisting, avoiding axial and radial forces as experienced during wire rope hoisting. This design effectively prevents minor deformation of the air knives and side baffles during hoisting, thus ensuring the overall precision of the galvanizing unit's air knife and side baffle equipment and improving the surface quality and coating control of galvanized products. Finally, the use of connectors and anti-detachment pins ensures the hoisting device is securely attached to the air knives and side baffles, preventing swaying or detachment during hoisting. The entire hoisting device design not only considers practicality but also safety and durability, ensuring stable and reliable operation even in harsh working environments.
