[0055] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0056] like Figure 1 and Figure 2 As shown, this embodiment of the present invention provides a sampling cart for graphite electrodes, comprising: a frame 1, movable wheels 2, and a mounting adjustment frame 3. The movable wheels 2 are disposed at the bottom of the frame 1. The sliding box of the mounting adjustment frame 3 is located at the top of the frame 1. A sampling drill 4 is mounted on the mounting adjustment frame 3.
[0057] In use, the sampling drill 4 is installed on the mounting and adjusting frame 3. Then, the frame 1 is moved to the location where sampling is required using the moving wheels 2. The height of the sampling drill 4 is adjusted using the mounting and adjusting frame 3 to facilitate its entry into the graphite electrode production furnace.
[0058] More specifically, such as Figure 1 and Figure 2 As shown, the mounting bracket 3 includes a mounting base 31, a height adjustment component 32, and a fixing component 33. The mounting base 31 is mounted on the top of the frame 1. The height adjustment component 32 is mounted on the mounting base. The fixing component 33 is mounted on the height adjustment component 32, and the fixing component 33 is provided with a mounting opening 34 for mounting the sampling drill 4.
[0059] During installation, the height adjustment component 32 is installed at the bottom of the mounting base 31, so that the sampling drill 4 is located below the mounting base 31 after installation.
[0060] In order to facilitate the use of production furnaces of different heights, the height of the sampling drill 4 can be adjusted by the height adjustment component 32.
[0061] In use, the sampling drill 4 is mounted on the frame 1, and the height of the sampling drill 4 is adjusted by the mounting bracket 3 mounted on the frame 1. During sampling, the frame 1 moves to the sampling point. Then, during sampling, the height adjustment component 32 moves linearly on the frame 1, and the frame 1 limits the height adjustment component 32 to prevent slippage or deviation during sampling.
[0062] The sampling drill 4 in this embodiment includes a sampling motor 41 and a water drill bit 42. The sampling motor 41 is mounted on the fixing member 33. The water drill bit 42 is mounted on the motor shaft of the sampling motor 41. The sampling motor 41 and the water drill bit 42 in this embodiment are both prior art, and their specific structures and working principles will not be described in detail here.
[0063] The samples taken by the sampling cart have a smooth surface without scratches, making them more representative and complete, easier to test, reducing sample preparation time, and lowering the frequency of sampling failures.
[0064] Using this sampling trolley can improve the quality of electrode sampling, increase work efficiency, save time and effort, and reduce the occurrence of safety accidents and the labor intensity of operators.

[0071] In one embodiment, such as Figure 1 and Figure 2 As shown, a rack 5 is provided on the mounting rod 13, and a gear 51 that cooperates with the rack 5 is provided on the mounting adjustment frame 3; a driving component 52 that is connected to the gear 51 is provided on the mounting adjustment frame 3.
[0072] To prevent slippage and misalignment of the mounting adjustment component during movement, a rack 5 is provided on the mounting rod 13, and a gear 51 that meshes with the rack 5 is provided on the mounting adjustment bracket 3. The driving component 52 connected to the gear 51 drives the mounting adjustment component to move on the mounting rod 13.
[0073] The engagement of gear 51 and rack 5 prevents slippage during movement.
[0074] In one embodiment, such as Figure 1 As shown, the sampling cart further includes a controller 6. The controller 6 is electrically connected to the drive unit 52. The controller 6 controls the movement of the drive unit 52, facilitating automatic sampling by the sampling cart.
[0075] In one embodiment, such as Figure 2 As shown, the mounting base 31 is provided with a mounting hole 35, and the side wall of the height adjustment component 32 is provided with a positioning hole 36. One end of the bolt 37 passes through the mounting hole 35 and the positioning hole 36 and is fixed by a nut 38.
[0076] To facilitate adjusting the distance between the height adjustment component 32 and the mounting base 31, the position of the nut 38 on the bolt 37 can be adjusted.
[0077] In one embodiment, such as Figure 3 As shown, the sampling trolley further includes a protective cover 7. The protective cover 7 is mounted on the sampling drill 4.
[0078] A protective cover 7 is installed on the sampling motor 41 of the sampling drill 4, which effectively improves the dust problem during sampling and reduces the damage of dust to the workers' bodies.
[0079] In one embodiment, such as Figure 4As shown, a handle 8 is provided on the top of the frame 1 to facilitate the movement of the frame 1.
[0080] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
