Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a locking device for an arc furnace electrode lifting structure. Background Art

[0002] An industrial furnace that generates arc heating through metal electrodes or non-metallic electrodes is called an electric arc furnace. The electrode is an indispensable part of the electric arc furnace. The electrode will gradually become shorter as it is consumed during use, and therefore needs to be replenished regularly. The electrode lifting structure is a mechanism that can change the length of the electrode extending into the electric arc furnace. The electrode lifting structure is generally equipped with a locking device for locking the electrode to clamp the electrode. After the locking device is installed on the lifting structure, if the locking device needs to be removed for maintenance or replacement, tools are required, which makes it inconvenient to quickly remove the locking device, affecting the maintenance or replacement of the locking device. Therefore, a locking device for an arc furnace electrode lifting structure is proposed to facilitate the disassembly and subsequent installation of the locking device. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] In order to facilitate disassembly and subsequent installation, as an embodiment of the present utility model, Figures 1 to 4As shown, the utility model discloses an arc furnace electrode lifting structure locking device, comprising a support 1 and two clamping blocks 2, wherein a bidirectional screw 50 is arranged in the support 1, a motor 5 is fixed to one side of the support 1 by bolts, and the output shaft of the motor 5 is connected to one end of the bidirectional screw 50 by a coupling, a slide groove for sliding the two clamping blocks 2 is arranged on the side of the support 1 close to the clamping block 2, and screw holes adapted to the bidirectional screw 50 are provided on the two clamping blocks 2, and anti-skid pads 3 are fixed to the opposite side walls of the two clamping blocks 2 by adhesive, and V-shaped grooves are arranged on the opposite side walls of the two anti-skid pads 3, which are convenient for clamping electrodes of different types, and the support 1 is far away from the slide groove. A protrusion 10 is integrally formed on one side, and a connecting seat 6 is provided on the side of the support 1 away from the slide groove. A plurality of mounting holes are provided on the connecting seat 6 away from the support 1, and a slot adapted to the protrusion 10 is provided on the connecting seat 6. A limit block 12 is provided above the protrusion 10, and a stop block 9 is welded and fixed to the top of the connecting seat 6. A connecting rod 11 is provided on one side of the limit block 12, and two through holes are provided on the stop block 9 for the ends of the connecting rod 11 to pass through. Both ends of the connecting rod 11 are welded and connected to the limit block 12, and two springs 14 are sleeved on the connecting rod 11, and the two springs 14 are located between the limit block 12 and the stop block 9, and the side of the limit block 12 away from the stop block 9 is constructed as an inclined surface.

[0024] When in use, bolts are used to fix the connecting seat 6 on the electrode lifting structure (existing technology, not shown). The connecting seat 6 can support the support 1, and the limit block 12 can prevent the support 1 from shaking. The output shaft of the motor 5 drives the bidirectional screw rod 50 to rotate, and the two clamping blocks 2 move toward each other. The two anti-skid pads 3 cooperate with the V-shaped grooves on the side walls of the anti-skid pads 3 to facilitate clamping the electrode. The electrode lifting structure drives the connecting seat 6 to rise and fall, and the electrode follows the rise and fall. If the support 1 needs to be removed, only the connecting rod 11 needs to be pulled, and the connecting rod 11 drives the limit block 12 to move. The block 12 releases the obstruction of the support 1, and the support 1 can be removed by moving the support 1 upward. During installation, the protrusion 10 is placed above the limit block 12 and then the support 1 is pushed down. The protrusion 10 squeezes the limit block 12, and the inclined surface of the side wall of the limit block 12 can make the limit block 12 move toward the stop block 9, which is beneficial to the position of the protrusion 10. After the protrusion is inserted into the slot on one side of the connecting seat 6, the spring 14 pushes the limit block 12 to reset, and the limit block 12 blocks the support 1. Only tools are needed during the first installation, and no tools are required for subsequent disassembly and installation, saving time and effort.

[0025] In order to facilitate holding the connecting rod 11, exemplary, as Figure 3 As shown, a first anti-slip sleeve 13 is fixed to the connecting rod 11 by adhesive.

[0026] In order to facilitate the placement and removal of the support 1, for example, Figure 1As shown, a handle 7 is welded and fixed to the top of the support 1, and a second anti-slip cover 8 is fixed to the handle 7 by adhesive.

[0027] In order to improve the stability of the clamping block 2, for example, Figure 1 As shown, a cross bar 4 is welded and fixed inside the support 1 , and through holes matching the cross bar 4 are formed on the two clamping blocks 2 .

[0028] In order to improve the stability of the bidirectional screw rod 50 , one end of the bidirectional screw rod 50 away from the motor 5 is rotatably connected to the support 1 .

[0029] When the utility model is in use, the connecting seat 6 is fixed to the electrode lifting structure (existing technology, not shown) by bolts, the connecting seat 6 can support the support 1, the limit block 12 can prevent the support 1 from shaking, the output shaft of the motor 5 drives the bidirectional screw 50 to rotate, the two clamping blocks 2 move toward each other, the two anti-skid pads 3 cooperate with the V-shaped grooves on the side walls of the anti-skid pads 3, and the electrode is conveniently clamped. The electrode lifting structure drives the connecting seat 6 to rise and fall, and the electrode rises and falls accordingly;

[0030] If the support 1 needs to be removed, just pull the connecting rod 11, the connecting rod 11 drives the limit block 12 to move, the limit block 12 releases the obstruction of the support 1, and the support 1 can be removed by moving the support 1 upward;

[0031] When installing the support 1, place the protrusion 10 above the limit block 12 and then push the support 1 downward. The protrusion 10 squeezes the limit block 12, and the inclined surface of the side wall of the limit block 12 can make the limit block 12 move toward the stop block 9, which is conducive to the positioning of the protrusion 10. After the protrusion is inserted into the slot on one side of the connecting seat 6, the spring 14 pushes the limit block 12 to reset, and the limit block 12 blocks the support 1. Only tools are needed during the first installation, and no tools are required for subsequent disassembly and installation, saving time and effort.
