With the continuous progress of the technology, the quantity of molten steel smelted in each furnace is continuously increased, and the heating power required to be provided for the molten steel by the electrode is continuously increased. The demand for high efficiency steel making has led to an increasing diameter of electrodes for LF or electric furnaces. 150 ton LF furnaces require electrodes with a diameter of more than 400 mm. The electrode is shortened due to continuous consumption in the production process, and the shortened electrode needs to be prolonged by connecting the shortened electrode with a new electrode end to end. In the electrode hoisting process, in order to prevent an electric shock accident from occurring when the electrode is connected, a large amount of manpower and material resources are needed to be used, the safety of the electrode connection operation is ensured to a large extent, particularly, after the electrode is powered off, a hoisting ring arranged at the tail part of the electrode is hooked by a crane (or an electric hoist), the tightening force of an electrode arm is released, the electrode is easy to shake, potential safety hazards are increased, the electrode which is subjected to lengthening operation needs to be hoisted to an operation field for operation, the electrode is large in size, smooth in surface and high in brittleness, when the electrode is subjected to lengthening operation, the electrode needs to be screwed, but the electrode is difficult to turn or rotate, therefore, an electrode screwing auxiliary device needs to be designed, and the electrode can be easily screwed when the electrode is subjected to lengthening operation.

Drawings
FIG. 1 is a schematic view of the apparatus of the present invention;
FIG. 2 is a cross-sectional view of the apparatus of the present invention;
labeled as: the clamp comprises a half backing ring 1, a spanner ring 2, a bolt 3, a connecting plate 4, a handle 5, a clamp head 6, a bolt 7, a movable clamp jaw 8, a fixed clamp jaw 9 and an electrode 10.
Detailed Description
The invention is described in further detail below with reference to the figures and the detailed description.
As shown in the attached drawings, the electrode screwing auxiliary device comprises a half supporting ring 1, a wrench ring 2, a bolt 3, a connecting plate 4, movable clamps, a bolt 7 and a fixed jaw 9, wherein the half supporting ring 1 is of a semicircular steel structure, the wrench ring 2 is in a semicircular strip shape and is fixedly connected to the surface of the inner cavity of the half supporting ring 1, each movable clamp comprises a handle 5, a clamp head 6 and a movable jaw 8, the clamp head 6 is of a sheet structure, the middle of one end of each clamp head is fixedly connected with a long strip-shaped handle 5, the end face of the other end of each clamp head is fixedly connected with the corresponding strip-shaped movable jaw 8, the bolt hole is formed in the clamp head 6, one end of the half supporting ring 1 is provided with the bolt hole, the two connecting plates 4 are respectively assembled with the bolt holes in the clamp head 6 and the half supporting ring 1 through the bolt 7 and the bolt 3, and the movable clamps can rotate around the bolt 3. The side surfaces of the fixed jaw 9 and the movable jaw 8 are toothed. The side end surfaces of the wrench ring 2, the fixed jaw 9 and the movable jaw 8 are on the same arc surface. The wrench ring 2 and the end face of the fixed jaw 9 are arranged in a central symmetry way. The length of the end face circular arc of the wrench ring 2 and the fixed jaw 9 is 80 mm. The wrench ring 2 has a thickness of 4 mm and a width of 48 mm. The thickness of the half trunnion ring 1 is 100 mm, and the width is 6 mm.
When the electrode needs to be screwed in lengthening operation, the fixed jaw 9, the movable jaw 8 and the wrench ring 2 radially surround the electrode 10, and the central angle corresponding to the arc of the surrounded part of the electrode is larger than 180 degrees and smaller than 270 degrees. The handle 5 is pushed by hand, the direction of the force is the opening direction of the wrench ring 2, and the pressure of the movable jaw 8, the fixed jaw 9 and the wrench ring 2 on the electrode is larger when the force applied by hand is larger. According to the static friction force formula, the friction force is in direct proportion to the positive pressure. Where the rotational torque experienced by the electrode is proportional to the frictional force experienced. Therefore, the greater the force applied by pushing the handle 5 with a hand, the greater the rotation torque applied to the electrode 10, and the rotation of the electrode 10 is realized, thereby completing the electrode tightening operation.
The electrode screwing device is simple in structure, low in cost and convenient to install, can easily realize the electrode screwing operation when the electrode is lengthened, has small damage to the surface of the electrode, and improves the operation efficiency.
