Description

[0001] The utility model relates to the technical field of power supply for aluminum electrolytic cells, in particular to a sliding busbar device used on a busbar. Background Art

[0002] In recent years, with the tightening of environmental protection and the widening gap in electricity costs, more and more electrolytic aluminum enterprises have begun to actively transfer their internal production capacity to resource-rich and energy-rich areas. Some backward production capacity will no longer start some electrolytic cells after the electrolytic cells gradually enter the overhaul period. Since the electrolytic cell is powered on by multiple electrolytic cells in series, the electrolytic cell that is no longer started means no power. By connecting the short-circuit busbars on both sides of the electrolytic cell column, the current passes through the short-circuit on the column and directly crosses the part of the electrolytic cell that is no longer started, bypassing to the next electrolytic cell column busbar in use, that is, short-circuiting to achieve the purpose of energy saving. In order not to affect the operation of other equipment on the ground, the installation of this busbar needs to be carried out overhead, generally 1.5 to 2 meters above the ground. The connection between the busbars is carried out by crimping. The traditional crimping method generally adopts the crimping method of square steel pipes and bolts. Workers need to climb to work, which is very inconvenient. In view of the above problems, a sliding busbar device is proposed that can facilitate the installation and disassembly of the busbar according to different location requirements.

[0020] In order to better explain the present invention and facilitate further understanding, the following Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0021] like Figure 1As shown, in this embodiment, a sliding busbar device for a busbar is installed on a fixed busbar 1, including a sliding busbar assembly 2, a sliding beam assembly 3, 8 half-shaft nut assemblies 8 and 4 double-headed left-right screws 6. The sliding busbar assembly 2 is arranged below the sliding beam assembly 3, and the 8 half-shaft nut assemblies 8 are fixedly arranged at both ends of the sliding beam assembly 3 and the sliding busbar assembly 2. The 4 double-headed left-right screws 6 penetrate into the half-shaft nut assembly 8 to thread the sliding busbar assembly 2 and the sliding beam assembly 3.

[0022] The sliding busbar assembly 2 includes a busbar block, a soft busbar 21, and a lifting beam assembly 4. The upper surface of the busbar block contacts the lower surface of the fixed busbar 1. Aluminum plates are welded on both sides of the busbar block in the width direction. The two aluminum plates match the width of the fixed busbar 1 and play a guiding role to ensure that the sliding busbar assembly 2 always moves along the length direction of the fixed busbar 1. Bolt holes are drilled on the lower surface of the busbar block at positions corresponding to the bolts. The two lifting beam assemblies 4 are respectively fixed to the two ends of the lower surface of the busbar block by bolts. The soft busbar 21 is welded to the lower surface of the busbar between the two lifting beam assemblies 4. Figure 4 As shown, the lifting beam assembly 4 includes a lifting beam bottom plate 41, two lifting beam vertical plates 42, four lifting beam ear plates 43 and two lifting beam limit plates 44. A bolt hole is provided in the middle of the lifting beam bottom plate 41, and the bolt passes through the bolt hole to fix the lifting beam bottom plate 41 to the busbar block; lifting beam limit plates 44 are welded to the two ends of the upper surface of the lifting beam bottom plate 41, and the two lifting beam limit plates 44 match the width of the busbar block, so that the lifting beam assembly 4 and the busbar block are relatively fixed in the horizontal direction. Lifting beam vertical plates 42 are welded to the two long side areas of the lower surface of the lifting beam bottom plate 41, and four lifting beam ear plates 43 are welded between the two lifting beam vertical plates 42, and the lifting beam ear plates 43 are evenly distributed in the length direction of the beam.

[0023] like Figure 2 and Figure 3As shown, the sliding beam assembly 3 includes two sliding beams, two polytetrafluoroethylene sliders 36 and a connecting plate 34. The sliding beam includes a sliding beam bottom plate 31, a sliding beam vertical plate 32, two sliding beam limit plates 35, and four sliding beam ear plates 33. The lower surface of the sliding beam bottom plate 31 is provided with a groove for installing the polytetrafluoroethylene slider 36. The polytetrafluoroethylene slider 36 is in contact with the fixed busbar 1, reducing the sliding resistance between the sliding beam assembly 3 and the fixed busbar 1. The two ends of the lower surface of the sliding beam bottom plate 31 are respectively welded with the sliding beam limit plates 35. The spacing between the two sliding beam limit plates 35 matches the width of the fixed busbar 1, ensuring that the sliding beam assembly 3 is not easy to get stuck or fall when sliding on the fixed busbar 1. The two long side areas of the upper surface of the sliding beam bottom plate 31 are welded with sliding beam upright plates 32, and four sliding beam ear plates 33 are welded between the two sliding beam upright plates 32. The sliding beam ear plates 33 are evenly distributed in the length direction of the beam. The two sliding beams are welded into a whole through a connecting plate 34 to ensure that the sliding beam assembly 3 slides synchronously.

[0024] like Figure 5 As shown, the half-shaft nut assembly 8 is welded by a square nut 81 and a half-shaft, and a round steel earring 82 is welded at the end away from the half-shaft to form a bolt-like structure. One set of sliding busbar device has 8 half-shaft nut assemblies 8, of which 4 are left-handed and the other 4 are right-handed. For the convenience of installation and use, the half-shaft nut assembly 8 installed on the lifting beam assembly 4 is left-handed, and the half-shaft nut assembly 8 installed on the sliding beam assembly 3 is right-handed. Corresponding to the left-handed and right-handed nuts respectively, the screw is rotated, and the two nuts either move closer to each other or move away from each other to achieve rapid tightening and rapid loosening. The half-shaft of the half-shaft nut assembly 8 matches the ear plate hole on the lifting beam ear plate 43 and the sliding beam ear plate hole on the sliding beam assembly 3. The half-shafts on the half-shaft nut assembly 8 pass through the ear plate holes in opposite directions and are connected by a connecting steel pipe 9 in the middle position to form a whole. In order to limit its axial movement, as Figure 6 As shown, two limiting rings 5 ​​are installed on the half shaft of each half shaft nut assembly 8, and each limiting ring 5 is provided with a top screw hole and a top screw 10. The round steel earrings 82 are convenient for ground operators to drag it.

[0025] Each set of sliding busbar device is provided with 4 double-headed left-right rotating screw rods 6, and each double-headed left-right rotating screw rod 6 corresponds to 2 left-right rotating half-shaft nut assemblies and is matched and installed. Such a double-headed left-right rotating screw rod 6 and the left-right rotating half-shaft nut assembly can be matched and installed to achieve fast tightening and fast loosening, which can effectively improve work efficiency.

[0026] To facilitate workers' operation on the ground, during installation, it is necessary to ensure that the end of the stud with a hexagonal cross-section column is facing downward, and workers can use an extended sleeve wrench to tighten it.

[0027] The use of the utility model:

[0028] The busbars of the electrolytic cell columns are connected through the fixed busbar 1. The utility model is overhead mounted on the fixed busbar 1 at one end of the electrolytic cell column, 1.5 to 2 meters above the ground. By changing the position of the utility model on the fixed busbar 1, the current crosses the part of the electrolytic cell busbar that is no longer started and detours to the next electrolytic cell column busbar in use, that is, the current is transmitted from the fixed busbar 1 to the other end connected to the soft busbar 21 through the soft busbar 21 of the device, without passing through the electrolytic cell busbar that is no longer used. When the sliding busbar assembly 2 needs to be shifted, the four double-headed left-right screws 6 are rotated, and the sliding busbar assembly 2 will move down under the action of gravity, leaving a gap between the sliding busbar assembly 2 and the fixed busbar 1 and can move freely, and the sliding busbar assembly 2 and the fixed busbar 1 are in a loose state; move the sliding busbar assembly 2 to the required position, and then rotate the four double-headed left-right screws 6, the sliding busbar assembly 2 will move up, and the sliding busbar assembly and the fixed busbar 1 are in a compressed state. The current on the fixed busbar 1 is transmitted to the soft busbar 21 through the sliding busbar assembly 2. The sliding busbar assembly 2 is moved by dragging and shifting the round steel earring 82 on the half-shaft nut assembly 8 with the help of a long-handled tool. The double-headed left-right screw 6 is operated by a worker standing on the ground and rotating it with the help of a long-handled sleeve wrench. The movement, loosening, and tightening of the sliding busbar device can be completed by workers on the ground with the help of a long-handled tool, without the need for high-altitude work, and is easy to operate.
