Technical Field

[0001] This application relates to the technical field of auxiliary devices for electrode production, and particularly to a hook device and a lifting equipment. Background Art

[0002] During the production process of electrodes, as one of the key raw materials, the powder is transported in powder barrels. During the transportation of the powder barrels, not only horizontal transportation is required, but also transportation from a high working position to a low working position. Currently, elevators and overhead cranes are often used to transport the powder barrels from a high working position to a low working position.

[0003] The elevator transportation has the following disadvantages: Elevators are usually large in size and require a large amount of installation space, which becomes a limiting factor in a production environment with limited space; The mechanical structure of the elevator is complex, and it is prone to failures during use and requires regular maintenance and repair, increasing the maintenance cost; During the transportation process, if the elevator fails, it may cause the powder barrel to fall, posing a safety hazard.

[0004] The overhead crane transportation has the following disadvantages: During the transportation process, a worker needs to stand at the high working position to connect the powder barrel with the overhead crane hook of the overhead crane. After the powder barrel is lifted to the low working position by the overhead crane, another worker needs to stand at the low working position to separate the overhead crane hook from the powder barrel. This not only increases the number of workers and the labor cost, but also the overhead crane may hit the worker at the low working position during the hoisting process, resulting in a safety accident, and the safety performance is poor.

The terms "set", "provided with", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components.

[0042] See Figure 1 、 Figure 2, a hook device provided by an embodiment of the present application includes a boom 10, a hook 11, and a pulling rope 12. A hanging hole 101 is provided at the upper end of the boom 10. One end of the hook 11 is hinged to the lower end of the boom 10 through a horizontally arranged hinge shaft 14. A closing part 13 for closing the opening of the hook 11 is also connected to the lower end of the boom 10. One end of the pulling rope 12 is connected to the hook 11, and when the pulling rope 12 is pulled upward, it drives the hook 11 to rotate around the hinge shaft 14 to open the opening of the hook 11.

[0043] The boom 10 is vertically arranged and is used to connect to the crane hook 201 of the overhead crane 20, serving as an extension arm. Exemplarily, the boom 10 can be made of steel plates, and a hanging hole 101 for hooking on the crane hook 201 is provided at the upper end of the boom 10. For example, a fixing ring can be welded to the upper end of the boom 10, and the inner hole of the fixing ring forms the hanging hole 101; the upper end of the boom 10 can also be directly drilled to form the hanging hole 101. Among them, the hanging hole 101 can be a long strip-shaped hole extending in the vertical direction.

[0044] The hook 11 is generally in a U-shaped structure. The hook 11 is arranged below the boom 10. One end of the hook 11 is connected to the boom 10 through a horizontally arranged hinge shaft 14, so that the hook 11 can rotate around the hinge shaft 14. Exemplarily, the hinge shaft 14 can include a bolt or a stud. During installation, first pass the bolt or stud through the hook 11 and the boom 10, and then connect the nut to one end of the bolt or both ends of the stud.

[0045] The closing part 13 is connected below the boom 10 and is located on one side of the opening of the hook 11. When the hook 11 is in the state of hanging a heavy object, the closing part 13 just closes the opening of the hook 11, preventing the heavy object from falling off the hook 11 and improving the reliability of the heavy object during the hoisting process. The boom 10 and the closing part 13 can be connected by welding or by fasteners such as bolts. To improve the connection strength between the boom 10 and the closing part 13, the boom 10 and the closing part 13 are of an integrally formed structure. Exemplarily, the closing part 13 is a long strip-shaped structure extending obliquely downward, and the cross-sectional dimension of the closing part 13 gradually increases from bottom to top to ensure the connection strength between the boom 10 and the closing part 13. When the heavy object is hung on the hook 11, to improve the reliability of the closing part 13 closing the opening of the hook 11, in some embodiments, a positioning hole 131 is provided on the side of the closing part 13 facing the hook 11, and the other end of the hook 11 is inserted into the positioning hole 131 when the closing part 13 closes the opening of the hook 11.

[0046] One end of the pulling rope 12 is connected to the hook 11. When the pulling rope 12 is pulled upward, the pulling rope 12 can drive the hook 11 to rotate around the hinge shaft 14, so that the other end of the hook 11 moves away from the closing part 13. This can not only open the opening of the hook 11, but also separate the heavy object hanging on the hook 11 from the hook 11. Exemplarily, a pull ring 15 is connected to the end of the pulling rope 12 away from the hook 11. During operation, the worker holds the pull ring 15 to pull the pulling rope 12. To facilitate the installation of the pulling rope 12, a retaining ring 16 is connected to the boom 10, and the pulling rope 12 passes through the retaining ring 16. Exemplarily, the retaining ring 16 is arranged adjacent to the upper end of the boom 10. To facilitate the connection between the pulling rope 12 and the hook 11, a connecting ring 17 is connected to the outside of the hook 11, and one end of the pulling rope 12 is connected to the connecting ring 17.

[0047] See Figure 1 , Figure 2 , an embodiment of the present application provides a lifting device, including an overhead crane 20 and a hook device. The overhead crane hook 201 of the overhead crane 20 is connected to the lifting hole 101 of the boom 10.

[0048] The embodiment of the present application provides a lifting device for transporting the powder barrel 30 from a high working position to a low working position. The specific transportation process is as follows:

[0049] See Figure 3 , after the powder barrel 30 is transported to the designated position at the high working position by the horizontal transportation device, the worker stands at the high working position and hangs the powder barrel hanging ring 301 of the powder barrel 30 on the hook 11, then controls the overhead crane 20 to lower the powder barrel 30 onto the rail trolley 40 at the low working position. Then, the worker at the high working position holds the pull ring 15 and pulls the pulling rope 12. The pulling rope 12 drives the hook 11 to rotate around the hinge shaft 14, separating the hook 11 from the powder barrel hanging ring 301. Then, the powder barrel 30 at the low working position can be transported away by the rail trolley 40.

[0050] The hook device and the lifting device provided by the embodiment of the present application utilize the cooperation between the hook device and the overhead crane 20 to realize the transportation of the powder barrel 30 from a high working position to a low working position. When the powder barrel 30 is transported to the low working position, the worker only needs to stand at a high place and pull the pulling rope 12 to separate the powder barrel 30 from the hook 11; compared with the existing elevator transportation, the hook device is connected to the overhead crane 20, does not occupy the on-site installation space, is not prone to failure during the transportation process, does not require regular maintenance and repair, and reduces the maintenance cost; compared with the existing overhead crane transportation, only one worker needs to stand at the high working position to operate during the transportation process, reducing the number of workers, reducing the labor cost, and improving the safety.

[0051] The above are only the preferred embodiments of the present application, and do not impose any formal restrictions on the present application. Based on the technical essence of the present application, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principles of the present application still fall within the protection scope of the technical solution of the present application.
