Description

Technical Field

[0001] The utility model relates to a special replacement wrench for a shell-breaking cylinder and belongs to the field of tools for replacing shell-breaking cylinders. Background Art

[0002] As the main equipment in the electrolytic aluminum production process, the shell breaking cylinder is mainly responsible for the shell breaking operation before feeding. When adding alumina powder to the electrolytic cell, the shell breaking hammer must be used to break the alumina shell surface so that the internal alumina powder can enter the electrolytic cell. The shell breaking hammer is driven by the shell breaking cylinder, and the shell breaking cylinder is fixed to the support by fastening bolts. In daily shell breaking operations, since the shell breaking cylinder provides a large force, it is subject to a large vibration force and is easily damaged. Therefore, the shell breaking cylinder often needs to be repaired or replaced.

[0003] When repairing or replacing the shelling cylinder, the fastening bolts need to be removed. In the prior art, workers usually use a wrench to perform the disassembly work. Due to the limited working space and deep position, workers usually need to lie on the ground to operate. In addition, due to the influence of the magnetic field and electric field in the working space, workers often cannot accurately clamp the fastening bolts, resulting in high labor intensity and low work efficiency. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a special replacement wrench for the shell breaking cylinder which is convenient for disassembling the fastening bolts.

[0005] The special replacement wrench for shell breaking cylinder described in the utility model comprises an extension rod made of stainless steel, a handle is welded on the upper end of the extension rod, a nut sleeve is fixedly connected to the lower end of the extension rod, a nut sleeve opening is provided at the bottom of the nut sleeve, and an insulating sleeve is connected to the nut sleeve and the outer side of the extension rod.

[0006] Furthermore, a socket is provided on the top of the nut sleeve, the extension rod is inserted into the socket, and the extension rod and the nut sleeve are welded and fixed, which can effectively ensure the connection stability between the extension rod and the nut sleeve.

[0007] Furthermore, the extension rod is welded to the right side of the middle part of the handle, so that the gripping parts of the handle are one short and one long, which not only makes it more convenient to use force, but also eliminates the influence of the working space to a certain extent.

[0008] Furthermore, a clamping rib corresponding to the handle is welded to the middle and upper end of the extension rod, and a bayonet is formed between the clamping rib and the handle. When the shell breaking cylinder is hoisted, the end of the nut sleeve held by the hand can clamp the shell breaking cylinder through the bayonet to prevent the shell breaking cylinder from shaking during hoisting.

[0009] Furthermore, the insulating sleeve is a heat shrinkable tape heat-sealed on the nut sleeve and the extension rod, which is easy to process on the one hand, and has a better fitting effect with the nut sleeve and the extension rod on the other hand.

[0010] Furthermore, the interior of the extension rod is a hollow structure, which can effectively reduce its own weight and make it easier for workers to hold it.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The special replacement wrench for the shell breaking cylinder described in the utility model eliminates the influence of limited working space and deep position by the design of the extension rod; eliminates the influence of the magnetic field in the working space by designing the extension rod to be made of stainless steel; eliminates the influence of the electric field in the working space by arranging an insulating sleeve on the outer side of the nut sleeve and the extension rod, thereby facilitating the worker to accurately clamp the nut sleeve on the fastening bolt, making the replacement operation of the shell breaking cylinder simple and convenient, which not only reduces the labor intensity of the workers but also improves the working efficiency.
