[0031] like Figures 1-4 The tool shown is a guide rod for drawing lines during busbar lifting operations, including an operating rod, a Y-shaped connecting rod 4, a drawing assembly, and an erasing assembly.

[0032] Specifically, the operating rod adopts a telescopic structure design and is composed of a fixed rod 1 and a movable rod 2. The fixed rod 1 is internally provided with a sliding hole. The movable rod 2 is coaxially and slidingly connected to the inside of the sliding hole of the fixed rod 1 at the lower part. A plurality of groups of threaded holes 101 are arranged on the side wall of the fixed rod 1 along the height direction at intervals. First tightening bolts 3 are threadedly connected in the threaded holes 101. The overall length of the operating rod can be adjusted by sliding the movable rod 2 up and down along the sliding hole in the fixed rod 1. After being adjusted to a suitable length, the first tightening bolts 3 are connected in the corresponding threaded holes 101 and the inner side end is tightly pressed against the outer side wall of the movable rod 2, so as to fix the position of the movable rod 2, so as to realize the adjustment and fixation of the length of the operating rod, thereby adapting to the operation requirements of different heights.

[0033] A Y-shaped connecting rod 4 is fixedly connected above the operating rod and is composed of a first connecting rod 5 and a second connecting rod 6 distributed at an included angle. The first connecting rod 5 and the second connecting rod 6 are respectively provided with a line drawing assembly and a line wiping assembly. The lower end of the Y-shaped connecting rod 4 is provided with an internal threaded hole, which can be threadedly connected with the upper end of the operating rod. In order to avoid relative rotation between the two during operation, a second tightening bolt 13 is also threadedly connected on the lower side wall of the Y-shaped connecting rod 4. One end of the second tightening bolt 13 penetrates through the lower side wall of the Y-shaped connecting rod 4 and is tightly pressed against the outer threaded part of the upper part of the movable rod 2, so as to fix and lock the two, so as to realize stable connection while being convenient for dismounting and replacing.

[0034] As shown in Figures 1-3 , the line drawing assembly comprises a chalk 7 and a pressing device for fixing the position of the chalk. The inside of the first connecting rod 5 is provided with a fixing hole 501 for accommodating the chalk 7. The chalk 7 is gap-fitted between the fixing hole 501. A groove 502 is arranged on the inner wall of the fixing hole 501. An adjusting hole 503 is arranged on the first connecting rod 5. The axis of the adjusting hole 503 is distributed perpendicular to the axis of the fixing hole 501 and communicates with the groove 502 after penetrating through the side wall of the first connecting rod 5. The pressing device is composed of a pressing arc-shaped plate 8 and a pressing bolt 9. The pressing arc-shaped plate 8 is an arc-shaped metal sheet with a curvature radius matching the outer diameter of the chalk 7 and can be slidingly connected in the groove 502 along the radial direction of the first connecting rod 5. The pressing bolt 9 is slidingly connected in the adjusting hole 503 and is fixedly connected with the pressing arc-shaped plate 8 at the end extending into the groove 502. The pressing bolt 9 can drive the pressing arc-shaped plate 8 to move radially along the fixing hole 501, so as to tightly press the pressing arc-shaped plate 8 against the outer wall of the chalk 7, thereby clamping the chalk 7 in the fixing hole 501. Moreover, the end of the pressing bolt 9 located outside the first connecting rod 5 is threadedly connected with a fixing nut 10. The pressing bolt 9 and the first connecting rod 5 are fixed by the fixing nut 10, so as to fix the position of the pressing arc-shaped plate 8 in the radial direction of the fixing hole 501, thereby preventing the pressing bolt 9 from loosening during operation.

[0035] The line wiping assembly is as shown in Figure 1And Figure 4 As shown, the rubber sleeve 11 is coaxially fixedly connected to the outer side of the second connecting rod 6, the outer side wall of the second connecting rod 6 is fixedly connected with an annular clamping table 12, the inner side wall of the rubber sleeve 11 is provided with a clamping groove matched with the clamping table 12, during installation, the rubber sleeve 11 can be expanded to a certain extent and then sleeved on the outer side of the second connecting rod 6 due to the elasticity of the rubber sleeve 11, when the clamping groove on the rubber sleeve 11 reaches the clamping table 12, the rubber sleeve 11 can be loosened, at this time, the two are clamped and connected through the cooperation of the clamping table 12 and the clamping groove, and the rubber sleeve 11 can also be prevented from sliding along the second connecting rod 6 in the axial direction during line wiping.

[0036] In the embodiment, the rubber sleeve 11 is made of polyurethane rubber material, has good wear resistance and elasticity, and the outer surface of the rubber sleeve 11 is provided with a convex or groove-shaped anti-skid wiping texture to improve the line wiping effect.

[0037] When the device is used to draw lines on the lifting bus guide rod, the length of the operating rod is adjusted according to the height of the horizontal position of the front guide rod and the bus before lifting, and then the length of the operating rod is fixed through the first tightening bolt 3; during line drawing operation, the chalk 7 at the end of the first connecting rod 5 is used to mark lines on the wall surface; when it is necessary to erase old lines, the operating rod is only rotated, and the rubber sleeve 11 at the end of the second connecting rod 6 is used for erasing, without the need to remove the operating rod and then repeatedly clamp the line wiping tool, and the line drawing assembly and the line wiping assembly are arranged at an angle, so that neither of the two assemblies will interfere with each other during line drawing or line wiping.

[0038] When it is necessary to replace the chalk 7, the second tightening bolt 13 can be removed first, and the Y-shaped connecting rod 4 can be removed to avoid the inconvenience of subsequent operation caused by the too long operating rod, then the fixed nut 10 is removed, the pressure bolt 9 is rotated to drive the pressure arc-shaped plate 8 away from the chalk 7, and then the chalk 7 is removed, a new chalk is inserted, the pressure bolt 9 is rotated again, and the new chalk is fixed in the fixed hole 501 through the pressure arc-shaped plate 8.

[0039] The device can quickly erase old lines and draw new lines, so as to accurately record the position of the bus, if the sliding occurs, the work personnel can use the overhead crane to quickly restore the height of the sliding anode according to the line drawing position of the front guide rod, reduce the fluctuation of the electrolytic cell, ensure the uniform conduction of the multiple anodes, and improve the stability and efficiency of the electrolytic aluminum production.

[0040] The above only describes the preferred embodiments of the present application, and it should be pointed out that those skilled in the art can make some improvements without departing from the principles of the present application, and these improvements should also be regarded as the protection scope of the present application.
