Description

Technical Field

[0001] This utility model relates to the field of clamping and adjusting mechanisms, specifically to an electrode clamping and adjusting mechanism for a refining furnace. Background Technology

[0002] The electrode clamping and adjusting mechanism of the refining furnace is a key device in the refining furnace system used to accurately control the electrode position and clamping state and to achieve flexible electrode adjustment. It plays an important role in arc heating, energy transfer and process control.

[0003] A search revealed a utility model for a graphite electrode clamping device in a refining furnace, with publication number CN215268785U. The device includes an upper clamping plate and a lower clamping plate for clamping the graphite electrode. An arc-shaped clamping block is fixed to the lower part of the upper clamping plate. An arc-shaped clamping groove that mates with the arc-shaped clamping block is provided on the lower clamping plate. An upper connecting rod is provided at the upper part of the upper clamping plate, and an upper power box is provided at the upper part of the upper connecting rod. A lower connecting rod is provided at the lower part of the lower clamping plate, and a lower power box is provided at the lower part of the lower connecting rod. The upper and lower power boxes are fixed to the refining furnace, and electric push rods are installed inside the upper and lower power boxes. This utility model, by setting up an arc-shaped upper and lower clamping plate, utilizes the interplay between the arc-shaped clamping block on the upper clamping plate and the lower clamping plate to clamp the graphite electrode. It can accommodate graphite electrodes of different sizes and provides excellent clamping stability.

[0004] The clamping device for the graphite electrode of the refining furnace in the aforementioned patent is simply designed to clamp and fix the electrode, but it lacks an adjustment structure and cannot meet the needs of different heights and rotation angles.

[0005] Therefore, it is necessary to invent a refining furnace electrode clamping and adjustment mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a refining furnace electrode clamping and adjusting mechanism. By turning on the first servo motor switch above the bracket, the lead screw is driven to rotate, which in turn moves the moving seat and the outer frame up and down, thereby adjusting the height. When it is necessary to rotate the entire electrode, by turning on the second servo motor switch on the other side above the bracket, the sliding rod, the external protrusion, and the first synchronous pulley are driven to rotate. When the first synchronous pulley rotates, it drives the external synchronous belt and the second synchronous pulley on the other inner side to rotate, so that the rotation of the second synchronous pulley drives the first bevel gear below to mesh with the second bevel gear on the other side. Finally, the second bevel gear drives the entire frame to rotate, thereby adjusting the position of the electrode. This solves the problem in the above-mentioned patent for refining furnace graphite electrode clamping device proposed in the background art, which only designs how to clamp and fix the electrode, but lacks an adjustment structure, and cannot meet the adjustment requirements of different heights and rotation angles.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a refining furnace electrode clamping and adjusting mechanism, including a bracket for supporting the refining furnace electrode clamping and adjusting device;

[0008] A first servo motor is fixedly mounted on one side above the bracket. A lead screw is fixedly connected to the output end of the first servo motor, and a movable seat is threaded onto the external part of the lead screw. A second servo motor is fixedly mounted on the other side above the bracket. A slide rod is fixedly connected to the output end of the second servo motor. A protrusion is fixedly connected to the outside of the slide rod. A first synchronous pulley is movably sleeved on the outside of the slide rod. A synchronous belt is movably sleeved on the outside of the first synchronous pulley. A second synchronous pulley is sleeved on the other side of the inside of the synchronous belt. A first bevel gear is fixedly connected below the second synchronous pulley. A second bevel gear is meshed with one side of the first bevel gear. A fixed rod is fixedly connected to the outside of the second bevel gear.

[0009] A frame is fixedly installed at one end of a fixed rod. A clamping assembly is provided inside the frame. The clamping assembly includes an electric push rod, which is fixed to the upper end of the frame. A movable seat is fixedly connected to the output end of the electric push rod. A first connecting frame and a second connecting frame are hinged inside the movable seat. A connecting rod is sleeved inside one end of the first connecting frame and the second connecting frame. A connecting seat is fixedly connected to one end of the connecting rod. A clamp is fixedly connected to the outside of the connecting seat.

[0010] Preferably, the movable seat is slidably connected to the slide rod, and the first synchronous pulley has a groove inside that matches the protrusion.

[0011] Preferably, the first synchronous pulley is rotatably connected to the interior of the movable seat below, and the second synchronous pulley is rotatably connected to the movable seat.

[0012] Preferably, the fixing rod passes through the interior of the movable seat, and the second bevel gear is rotatably connected to one side of the movable seat.

[0013] Preferably, a first slide rail is fixedly connected to the inner side of the frame, and the rear side of the movable seat slides in a limited manner with the first slide rail.

[0014] Preferably, a slider is fixedly connected to the lower part of the connecting seat, and a second slide rail is fixedly connected to the front side of the inner side of the frame. The connecting seat slides with the limiter via the slider.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This invention, through the arrangement of a movable seat, a first synchronous pulley, a synchronous belt, a second synchronous pulley, a first bevel gear, a second bevel gear, a fixed rod, a frame, and a clamping assembly, not only clamps the electrode but also allows for adjustment of the required position and height according to the electrode. The electrode is clamped between two sets of clamps. Once clamped and fixed, height adjustment is achieved by turning on the first servo motor switch above the bracket, which rotates the lead screw, causing the movable seat and the outer frame to move up and down. When the entire electrode needs to rotate, the second servo motor switch on the other side of the bracket is turned on, causing the slide rod, the external protrusion, and the first synchronous pulley to rotate. The rotation of the first synchronous pulley causes the external synchronous belt and the second synchronous pulley on the inner side to rotate, which in turn drives the first bevel gear below to mesh with the second bevel gear on the other side. Finally, the second bevel gear rotates the entire frame, thus adjusting the electrode's position. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The refining furnace electrode clamping and adjusting mechanism shown includes a bracket 1 for supporting the refining furnace electrode clamping and adjusting device.

[0027] The first servo motor 2 is fixedly installed on one side above the bracket 1. The output end of the first servo motor 2 is fixedly connected to the lead screw 3. The external thread of the lead screw 3 is connected to the movable seat 4. The second servo motor 5 is fixedly installed on the other side above the bracket 1. The output end of the second servo motor 5 is fixedly connected to the slide rod 6. The external part of the slide rod 6 is fixedly connected to the protrusion 7. The external part of the slide rod 6 is movably fitted with the first synchronous pulley 8. The external part of the first synchronous pulley 8 is movably fitted with the synchronous belt 9. The internal side of the synchronous belt 9 is fitted with the second synchronous pulley 10. The lower part of the second synchronous pulley 10 is fixedly connected to the first bevel gear 11. The first bevel gear 11 is meshed with the second bevel gear 12 on one side. The external part of the second bevel gear 12 is fixedly connected to the fixed rod 13.

[0028] The frame 14 is fixedly mounted on one end of the fixed rod 13. A clamping assembly 15 is installed inside the frame 14. The clamping assembly 15 includes an electric push rod 1501, which is fixed to the upper end of the frame 14. A movable seat 1502 is fixedly connected to the output end of the electric push rod 1501. A first connecting frame 1504 and a second connecting frame 1505 are hinged inside the movable seat 1502. A connecting rod 1506 is sleeved inside one end of the first connecting frame 1504 and the second connecting frame 1505. A connecting seat 1507 is fixedly connected to one end of the connecting rod 1506. A clamp 1510 is fixedly connected to the outside of the connecting seat 1507. The clamping assembly 1510 is opened by the bracket 1. The switch of the first servo motor 2 at the top drives the lead screw 3 to rotate, which in turn moves the moving seat 4 and the outer frame 14 up and down to adjust the height. When it is necessary to rotate the entire electrode, the switch of the second servo motor 5 on the other side above the bracket 1 is turned on, which drives the slide rod 6, the external protrusion 7, and the first synchronous pulley 8 to rotate. When the first synchronous pulley 8 rotates, it drives the external synchronous belt 9 and the second synchronous pulley 10 on the other side to rotate. This causes the second synchronous pulley 10 to rotate, which in turn drives the first bevel gear 11 below to mesh with the second bevel gear 12 on the other side. Finally, the second bevel gear 12 drives the entire frame 14 to rotate, thereby adjusting the position of the electrode.

[0029] like Figure 2 As shown, the movable seat 4 is slidably connected to the slide rod 6. The first synchronous pulley 8 has a groove inside that matches the protrusion 7. When the first servo motor 2 is switched on, it drives the lead screw 3 to rotate. The rotation of the lead screw 3 drives the movable seat 4 to rise and fall. During the rising and falling process, the movable seat 4 moves to a limited position outside the slide rod 6 through the first synchronous pulley 8 inside, thereby enhancing the stability of the movable seat 4 during the movement process.

[0030] like Figure 2 and Figure 3 As shown, the first synchronous pulley 8 is rotatably connected to the lower interior of the movable seat 4, and the second synchronous pulley 10 is rotatably connected to the movable seat 4. When the first synchronous pulley 8 is directly clamped by the slide rod 6, and the outside of the first synchronous pulley 8 is rotatably connected to the movable seat 4, the first synchronous pulley 8 can rotate inside the movable seat 4 when the second servo motor 5 drives the slide rod 6 to rotate. Then, the second synchronous pulley 10 on the other side is driven to rotate through the synchronous belt 9.

[0031] like Figure 2 and Figure 3 As shown, the fixed rod 13 passes through the interior of the movable seat 4, and the second bevel gear 12 is rotatably connected to one side of the movable seat 4. The second bevel gear 12 is driven by the meshing of the first bevel gear 11, thereby driving the fixed rod 13 and the rear frame 14 to rotate and adjust in the front side of the movable seat 4.

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, a first slide rail 1503 is fixedly connected to the inner side of the frame 14. The rear side of the movable seat 1502 slides in a limited manner with the first slide rail 1503. When the electric push rod 1501 pushes the movable seat 1502 to rise and fall within the frame 14, the movable seat 1502 is enhanced in stability during the rising and falling process by passing through the first slide rail 1503 on the rear side.

[0033] like Figure 4 and Figure 5 As shown, a slider 1508 is fixedly connected to the lower part of the connecting seat 1507, and a second slide rail 1509 is fixedly connected to the front side of the inner side of the frame 14. The connecting seat 1507 slides with the limiter through the slider 1508. When the two sets of connecting seats 1507 move in the frame 14, they drive the clamp 1510 to move closer to each other for clamping. The slider 1508 below slides outside the second slide rail 1509 above the frame 14, thereby enhancing the stability during the moving clamping process.

[0034] The working principle of this utility model is as follows: First, connect the external power supply. Then, place the electrode between the two sets of clamps 1510. Next, turn on the electric push rod 1501 switch above the frame 14, which drives the movable seat 1502 to extend and retract. During the extension and retraction, the first connecting frame 1504 and the second connecting frame 1505 move closer to each other. When the first connecting frame 1504 and the second connecting frame 1505 move closer, they drive the two sets of connecting rods 1506, the connecting seat 1507, and the clamps 1510 to clamp and fix the electrode on the outside. When the height needs to be adjusted after clamping and fixing, turn on the first servo motor 2 switch above the bracket 1, which drives the lead screw 3 to rotate. The rotation of the lead screw 3 drives the movable seat 4 to move with the outer frame 14 and the clamped electrode. The height can be adjusted by moving the lever up and down. When it is necessary to rotate the entire electrode, the second servo motor 5 on the other side above the bracket 1 is switched on, which drives the slide rod 6 and the external protrusion 7 to rotate. When the slide rod 6 rotates, it drives the first synchronous pulley 8, which is rotatably connected inside the moving seat 4, to rotate. When the first synchronous pulley 8 rotates, it drives the external synchronous belt 9 and the second synchronous pulley 10 on the other side to rotate. This causes the second synchronous pulley 10 to rotate, which drives the first bevel gear 11 below and the second bevel gear 12 on the other side to mesh and transmit power. Finally, the second bevel gear 12 drives the fixed rod 13 and the entire frame 14 and the clamped electrode to rotate. This completes the use of the electrode clamping and adjusting mechanism of the refining furnace.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
