DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The purpose of the present invention is to provide a hoist for vertically lifting electrolytic cell components to solve the problems existing in the above-mentioned prior art, to achieve vertical lifting of the components to be replaced, and to improve the lifting safety.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-6 As shown, this embodiment provides a lifting device for vertically lifting electrolytic cell components, including a hanging plate body 1. The specific structure of the hanging plate body 1 is as follows: Figure 1 As shown, a lifting belt connection hole 101 is provided in the middle position of the upper end of the hanging plate body 1. The lifting belt connection hole 101 is used to connect the lower end of the lifting belt, and the upper end of the lifting belt is used to connect the lifting device, which is the hook structure of the crane.

[0032] The lower end of the hanger plate body 1 is provided with several hook hole groups, each hook hole group includes two hook connecting holes, and the two hook connecting holes in each hook hole group are symmetrically distributed on both sides of the lower end of the hanger plate body 1. Each hook connecting hole is used to connect a hook assembly, and the hook assembly is used to connect the parts that need to be hoisted.

[0033] In actual use, the upper end of the lifting strap is simply connected to the crane hook, the lower end of the lifting strap is connected to the lifting strap connection hole 101, and the two hook connection holes in the same group are each connected to an identical hook assembly. The lower ends of the two sets of hook assemblies are connected to the component to be replaced. Since two sets of hook assemblies are used, the stability of the component lifting process can be effectively guaranteed.

[0034] In this embodiment, if Figure 1 As shown, the hanging plate body 1 is a triangular plate with a stable structure, and can ensure that the two hook connection holes in the hook hole group are evenly stressed, thereby enhancing the hanging stability of the component to be replaced.

[0035] In this embodiment, the thickness of the hanging plate body 1 is 10 mm, and its material is selected from 304 stainless steel to meet the lifting bearing capacity.

[0036] In this embodiment, there are two groups of hook connection holes, namely, a shelling cylinder hook hole group and a blanking device hook hole group. The shelling cylinder hook hole group includes two shelling cylinder hook connection holes 102, which are respectively arranged on both sides of the lower end of the hanging plate body 1. Each shelling cylinder hook connection hole 102 is used to connect a shelling cylinder hook assembly 2, and the lower end of the shelling cylinder hook assembly 2 is used to connect to the shelling cylinder body 4. Similarly, the blanking device hook hole group includes two blanking device hook connection holes 103, which are respectively arranged on both sides of the lower end of the hanging plate body 1. Each blanking device hook connection hole 103 is used to connect to a blanking device hook assembly 3, and the lower end of the blanking device hook assembly 3 is used to connect to the blanking device body 5.

[0037] In this embodiment, the apertures of the shelling cylinder hook connection hole 102 and the blanking device hook connection hole 103 are both 20 mm, wherein the center spacing between the two shelling cylinder hook connection holes 102 is 270 mm, which is adapted to the size of the shelling cylinder body 4 below, and the center spacing between the two blanking device hook connection holes 103 is 180 mm, which is adapted to the size of the blanking device body 5 below. It can be concluded that the two shelling cylinder hook connection holes 102 are located outside the two blanking device hook connection holes 103. Of course, the art can also appropriately adjust the spacing between the two shelling cylinder hook connection holes 102 and the spacing between the two blanking device hook connection holes 103 according to the specific sizes of the actual shelling cylinder body 4 and the blanking device body 5, and is not limited to this method.

[0038] In this embodiment, if Figure 3 As shown, the shelling cylinder hook assembly 2 includes a shelling cylinder hook body 201, the upper end hook portion of the shelling cylinder hook body 201 is used to connect with the shelling cylinder hook connecting hole 102, and the lower end connecting portion of the shelling cylinder hook body 201 is connected to a screw connecting piece 203 through a connecting rod 202. The length of the connecting rod 202 is 350 mm, and the screw connecting piece 203 is used to connect with the screw on the shelling cylinder body 4.

[0039] In the actual lifting process, Figure 2 As shown, since the hanging plate body 1 is provided with two shell-breaking cylinder hook connection holes 102, the lower end of the hanging plate body 1 is connected to two shell-breaking cylinder hook assemblies 2, and the screw connectors 203 in the two shell-breaking cylinder hook assemblies 2 are used to respectively connect to the two screws on the shell-breaking cylinder body 4. Furthermore, in order to maintain the stability of the shell-breaking cylinder body 4 during the lifting process, the two screw connectors 203 are preferentially connected to the two screws on the diagonal sides of the shell-breaking cylinder body 4.

[0040] In this embodiment, the specific structure of the screw connector 203 is as follows: Figure 4 As shown, the screw connection member 203 includes a U-shaped member and a threaded pin. Figure 4 The distance between the uppermost end (i.e., the end of the arc portion) and the lowermost end (i.e., the open end) of the U-shaped member is 200 mm, and the radius of the arc of the U-shaped member is 75 mm. The lower end of the connecting rod 202 is welded to the center of the arc portion of the U-shaped member. The first open end of the U-shaped member is provided with a stopper hole, through which a threaded pin can pass until the tail of the threaded pin abuts against the stopper pin. The second open end of the U-shaped member is provided with an internal threaded hole, and the head of the threaded pin is provided with external threads. The head of the threaded pin is threadedly connected to the internal threaded hole, thereby forming a closed annular structure of the screw connector 203.

[0041] In actual use, the preparation work for lifting can be completed by simply inserting the screw connected to the shell-breaking cylinder body 4 into the annular structure formed by the U-shaped piece and the threaded pin.

[0042] It is not difficult to infer from this that those skilled in the art can also appropriately design the screw connector 203 into other annular structures, including but not limited to circular ring structures.

[0043] In this embodiment, the cross-sectional diameter of the connecting rod 202 and the U-shaped member is 10 mm. The connecting rod 202 and the U-shaped member are made of stainless steel, have a strong structure, and are not easy to break, thereby ensuring the service life of the shell-breaking cylinder hook assembly 2.

[0044] In this embodiment, if Figure 5 As shown, the feeder hook assembly 3 includes a first feeder hook 301, a chain 302, and a second feeder hook 303. The first feeder hook 301 and the second feeder hook 303 are respectively fixed to the upper and lower ends of the chain 302. The hook portion of the first feeder hook 301 is used to connect with the feeder hook connection hole 103, and the hook portion of the second feeder hook 303 is used to connect with the ear on the feeder body 5.

[0045] In the actual lifting process, Figure 5 As shown, since the hanging plate body 1 is provided with two feeder hook connection holes 103, the lower end of the hanging plate body 1 is connected to two feeder hook assemblies 3, and the feeder second hooks 303 in the two feeder hook assemblies 3 are used to respectively connect to the two lifting ears on the feeder body 5. Furthermore, in order to maintain the stability of the feeder body 5 during the lifting process, the two feeder second hooks 303 are preferentially connected to the two lifting ears on the diagonal corners of the feeder body 5.

[0046] In addition, the shell breaking cylinder hook body 201, the first hook 301 of the blanking device and the second hook 303 of the blanking device are all provided with anti-slip clips to avoid the risk of separation from the connected components during the lifting process.

[0047] In this embodiment, the length of the chain 302 is 200 mm, and the material of the chain 302 is stainless steel. Figure 6 As shown, the chain 302 is composed of multiple links connected end to end, with each link having a length (i.e., maximum diameter) of 18 mm and a cross-sectional diameter of 6 mm. This ensures the robustness of the chain 302, improves its load-bearing capacity, and guarantees its service life.
