Description

Technical Field

[0001] The utility model relates to a manual assembly of a small box clamp for an aluminum electrolytic cell and a tightening wrench, belonging to the technical field of electrolytic aluminum production. Background Art

[0002] After replacing the anode in the electrolytic cell, if the voltage drop increases, it is necessary to manually tighten the small box clamp. This is because after the anode is replaced, there may be problems with the contact between the anode and the adjacent anode, resulting in uneven current distribution, which in turn causes an increase in voltage drop. Manually tightening the small box clamp can adjust the contact between the anodes to make them tighter, thereby improving current distribution and reducing voltage drop.

[0003] In the process of implementing the technical solution of this application, the inventor discovered that there are at least the following technical problems in the prior art:

[0004] When re-tightening is required, the construction workers need to stand at a high place to re-tighten due to the wrench. The construction workers usually stand on the electrolytic cell cover and use a wrench to re-tighten the small box clamp. When re-tightening with force, the construction workers are prone to slipping and falling, and the adjustment is not very convenient. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a manual installation of a tightening wrench for a small box clamp of an aluminum electrolytic cell, so that construction workers can tighten it on the ground and avoid high-altitude operations, which is easy to use.

[0006] The utility model discloses a manual tightening wrench for a small box clamp of an aluminum electrolytic cell, comprising a ratchet locking wrench, a tightening portion being provided at one end of the wrench, a mounting tube being fixedly connected to the end of the wrench away from the tightening portion, an insulating portion being connected to one side of the mounting tube, an extension tube being connected to one end of the insulating portion, and an insulating handle being provided at the end of the extension tube away from the insulating portion.

[0007] Furthermore, the insulating part comprises an insulating column for connection, and both ends of the insulating column are provided with built-in cylindrical blocks for matching the installation tube and the extension tube for installation.

[0008] Furthermore, the insulating part also includes a rubber pad sleeved on the built-in cylindrical block, and the outer ring of the built-in cylindrical block is provided with a slot for installing the rubber pad.

[0009] Furthermore, a locking screw for connection is provided between the extension tube and the built-in cylindrical block; and a locking screw for connection is provided between the installation tube and the built-in cylindrical block.

[0010] Furthermore, the insulating handle is coated with an insulating layer or wrapped with an insulating tape.

[0011] Furthermore, the extension tube is made of a stainless steel pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model is designed with an extended tube and an insulating part, so that workers can operate on the ground without having to stand on the electrolytic cell cover to perform re-tightening work, thereby avoiding the safety risks brought by high-altitude operations. At the same time, the insulating part design avoids the risk of electric shock, and the insulation is enhanced by the insulating handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1

[0027] like Figure 1 to Figure 5 As shown, the aluminum electrolytic cell small box clamp re-tightening wrench manual assembly described in the utility model includes a ratchet locking wrench 1, a tightening part 11 is provided at one end of the wrench 1, an installation tube 2 is fixedly connected to the end of the wrench 1 away from the tightening part 11, an insulating part 3 is connected to one side of the installation tube 2, an extension tube 4 is connected to one end of the insulating part 3, and an insulating handle 5 is provided at the end of the extension tube 4 away from the insulating part 3.

[0028] The insulating part 3 includes an insulating column 31 for connection. Both ends of the insulating column 31 are provided with built-in cylindrical blocks 32 for matching the installation tube 2 and the extension tube 4. The insulating column 31 can be made of wood or other insulating materials.

[0029] The insulating part 3 also includes a rubber pad 33 mounted on the built-in cylindrical block 32. The outer ring of the built-in cylindrical block 32 is provided with a slot for installing the rubber pad 33. The rubber pad 33 is used for locking. Simple connection is prone to loosening after long-term use. The rubber pad 33 can enhance connectivity.
