AI Technical Summary
In the electrolysis workshop, the upper mechanism of the aluminum electrolytic cell is easily dropped during the lifting process. The prior art uses wire rope to bind the load-bearing trusses unstable, which can easily lead to accidents.
A lifting device for the upper mechanism of an aluminum electrolytic cell is designed, using a left hook and a right hook hinged with a pin shaft. A hanging hole is provided on the top of the right hook. The left hook is fish hook-shaped and the right hook is ear-shaped. The limiting gear lever prevents excessive clamping, providing a stable lifting hole structure for ease of lifting.
The device is more stable during the lifting process, avoiding the risk of the upper mechanism falling, making it easy to use, and improving the safety and reliability of the lifting.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hoisting devices, in particular to a hoisting device for an upper mechanism of an aluminum electrolytic cell. Background Art
[0002] The aluminum electrolytic cells in the electrolysis workshop operate continuously for a long time. During the overhaul of the damaged electrolytic cells, all the upper structures of the cells need to be lifted out of the cell shell for cleaning and maintenance. In the past, steel wire ropes were used to bind the load-bearing trusses of the upper structures to lift them out. The steel wire ropes are heavy and difficult to bind, and the angle after binding is large, which makes it easy for the upper structures to fall. Utility Model Content
[0003] The main purpose of the utility model is to provide a hoisting device for the upper mechanism of an aluminum electrolytic cell, so as to solve the problem that the upper mechanism of the aluminum electrolytic cell is prone to fall when hoisting the upper mechanism of the aluminum electrolytic cell in the above-mentioned prior art.
[0004] In order to achieve the above purpose, the utility model provides an aluminum electrolytic cell upper mechanism lifting device, including a left hook and a right hook hinged by a pin shaft, and a lifting hole for connecting with the lifting hook is provided on the top of the right hook, and the lifting hole is located on the upper left of the pin shaft.
[0005] Furthermore, there are two left hooks, which are arranged side by side in the front-to-back direction and fixedly connected, and the right hook is located between the two left hooks and hinged to the tops of the two left hooks; by setting two left hooks, the load-bearing truss is more stable when hooked upwards.
[0006] Furthermore, a limit lever is provided on the part of the right hook located on the right side of the pin shaft, and the limit lever is used to avoid further clamping between the left hook and the right hook after clamping to a certain degree; the limit lever is used to prevent the left hook and the right hook from being clamped too tightly to prevent the load-bearing truss from being clamped.
[0007] Furthermore, the hanging hole is a waist hole; the hanging hole is set as a waist hole, which is more stable when connected with the hook.
[0008] Furthermore, the left hook is in the shape of a fishhook, and the right hook is in the shape of an ear.
[0009] The utility model discloses an aluminum electrolytic cell upper structure hoisting device, which can cooperate with the hoisting hook to hoist the load-bearing truss; the left hook can be clamped from the left side of the load-bearing truss, and the right hook can be clamped from the right side of the load-bearing truss. The hoisting device is easy to use and avoids the problem of the upper structure easily falling off during hoisting. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0017] Example 1
[0018] like Figures 1 to 3 As shown, a lifting device for the upper structure of an aluminum electrolytic cell includes a left hook 1 and a right hook 2 hinged by a pin shaft 3, the left hook 1 is in the shape of a fishhook, the right hook 2 is in the shape of an ear, and a lifting hole 4 for connecting with the lifting hook is provided on the top of the right hook 2, and the lifting hole 4 is located on the upper left of the pin shaft 3.
[0019] There are two left hooks 1, which are arranged side by side in the front-to-back direction and fixedly connected, and the right hook 2 is located between the two left hooks 1 and hinged to the tops of the two left hooks 1; by setting two left hooks, the load-bearing truss is more stable when hooked upwards.
[0020] The hanging hole 4 is a waist hole; the hanging hole is set as a waist hole, which is more stable when connected with the hook.
[0021] When hoisting the load-bearing truss 6, firstly clamp the left hook 1 with the load-bearing truss 6 from the left, and clamp the right hook 2 with the load-bearing truss 6 from the right; then hang the hook with the lifting hole 4; finally, lift the load-bearing truss 6.
