In the figure: 1. a contact plate; 2. a spring; 3. a connecting rod; 4. i-shaped steel; 5. a grounding device; 6. carrying out buggy ladle; 7. a pulley; 8. a support frame; 9. a pulley plate; 10. and (5) rolling the steel.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, a earthing device 5 for refining furnace buggy ladle 6, including support frame 8, support frame 8 is installed on refining furnace buggy ladle 6 lateral wall, and support frame 8 one side is changeed to rotate and is connected with contact plate 1, and the support frame 8 other end is provided with spring 2, and 2 one end of spring is connected on support frame 8, and the other end is connected on contact plate 1.
The grounding device 5 is integrally made of conductive metal materials, the grounding device 5 is installed on the buggy ladle 6 and moves together with the buggy ladle 6 to play a role in connecting the grounding between the buggy ladle 6 and the I-steel 4, the buggy ladle 6 and the I-steel 4 are connected together through the contact plate 1, the spring 2 can play a role in preventing looseness, the contact plate 1 is pushed against the I-steel 4, and the phenomenon that the grounding effect is not good due to poor contact between the contact plate 1 and the I-steel 4 is avoided.
In one embodiment, as shown in fig. 2, the contact plate 1 is connected with a connecting rod 3, the supporting frame 8 is correspondingly provided with a hole matched with the connecting rod 3, the connecting rod 3 extends from the hole to the lower part of the supporting frame 8, and one end of the connecting rod 3, which is located below the supporting frame 8, is connected with a nut through a thread.
The length of connecting rod 3 below supporting frame 8 is adjusted through rotating the nut, can adjust the size of the frictional force of contact plate 1 and the contact of I-steel 4, and the longer the length that connecting rod 3 is located the supporting frame 8 below, contact plate 1 is more down compression spring 2, and the frictional force between contact plate 1 and the I-steel 4 correspondingly reduces, through connecting rod 3 and nut, can adjust the contact degree between contact plate 1 and the I-steel 4 and satisfy the requirement of effective ground connection, can not cause wearing and tearing because of frictional force is too big again.
