Description

Technical Field

[0001] This utility model relates to the field of submerged arc furnace technology, and in particular to an electrode pressure measurement device. Background Technology

[0002] In electric arc furnace smelting processes, electrodes are key components, and their working ends are continuously consumed during the smelting process. To ensure smelting efficiency and continuous electrode use, electrodes need to be periodically depressed using an electrode depressing device to replenish the consumed portion and maintain a constant working length. Precise control of the electrode depressing amount depends on real-time monitoring of the electrode consumption rate, i.e., real-time monitoring of changes in electrode length.

[0003] A search revealed an electrode pressing and releasing measuring device with application number 202121943331.0. Its structure includes a measuring mechanism and a buffer clamping mechanism. The measuring mechanism comprises a measuring wheel, a first pulley, a belt, and a second pulley. The measuring wheel is fixedly sleeved in the middle of a first rotating shaft. Both ends of the first rotating shaft are rotatably connected to their respective first bearing seats. A first pulley is also fixedly sleeved on the first rotating shaft, and a belt is provided between the first pulley and the second pulley. The buffer clamping mechanism includes a fixed plate, a clamping rod, a fixed seat, and a spring. A groove is provided on the inner side of the fixed plate. This utility model, through the action of the belt and spring, can always keep the measuring wheel pressed tightly against the outer wall of the electrode cylinder. This solves the problem that weld beads or pits on the surface of the electrode cylinder, poor contact between the measuring wheel and the outer wall of the electrode cylinder, slippage, or incomplete and ineffective frictional resistance can cause the measuring wheel to not rotate, resulting in no detection of stroke displacement and consequently, no data.

[0004] During use, although the buffer clamping mechanism can always keep the measuring wheel pressed tightly against the outer wall of the electrode cylinder, this can easily cause the belt in the device to loosen and slip on the pulley. This results in the encoder being unable to accurately capture the rotation information of the measuring wheel, thus affecting the measurement accuracy and stability of the electrode pressing depth.

[0005] Therefore, it is necessary to provide a new electrode pressure discharge measurement device to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the technical problem that existing electrode pressing and releasing measurement devices suffer from belt slackening during use, which affects the measurement accuracy and stability of electrode pressing and releasing depth, this invention provides an electrode pressing and releasing measurement device.

[0007] The electrode pressing and releasing measuring device provided by this utility model includes: a housing, an inner housing inside the housing, two fixing plates on the inner housing, a first rotating shaft rotatably mounted on the two fixing plates, a first pulley fixedly sleeved on the first rotating shaft; a measuring wheel fixedly sleeved on the first rotating shaft, the measuring wheel having anti-slip teeth fixedly mounted on it, the anti-slip teeth contacting the electrode cylinder; an encoder fixedly mounted on the inner wall of the inner housing, a second rotating shaft fixedly mounted on the input end of the encoder, a second pulley fixedly sleeved on the second rotating shaft; a belt sleeved on the first pulley and the second pulley; multiple buffer mechanisms mounted on the housing for buffering the inner housing; and a pressing mechanism assembled on the inner housing for tensioning the belt.

[0008] Preferably, the buffer mechanism includes: a groove formed on the inner wall of the outer shell, a slide rod fixedly installed on the inner wall of the groove, a first spring slidably sleeved on the slide rod; and a slider slidably installed on the slide rod, the slider being fixedly connected to the inner shell.

[0009] Preferably, the clamping mechanism includes: a plurality of second springs fixedly installed on the inner wall of the inner shell; a pressure plate fixedly installed on the plurality of second springs, a mounting bracket fixedly installed on the pressure plate, a pressure wheel rotatably installed on the mounting bracket, and the pressure wheel contacting the belt.

[0010] Preferably, a plurality of limiting rods are fixedly installed on the inner wall of the inner shell, and the plurality of limiting rods are slidably connected to the pressure plate.

[0011] Preferably, both fixing plates are fixedly installed on the inner wall of the inner shell by bolts, and both the outer shell and the inner shell are configured in a U-shape.

[0012] Preferably, each of the plurality of limiting rods has a baffle fixedly installed at its bottom end, and the plurality of baffles are used to block the pressure plate.

[0013] Preferably, the plurality of first springs and the plurality of second springs are all made of stainless steel, and one end of the second rotating shaft is rotatably connected to the inner wall of the inner shell.

[0014] Compared with related technologies, the electrode pressing and discharging measuring device provided by this utility model has the following beneficial effects:

[0015] This invention provides an electrode pressing and releasing measuring device. Through the coordinated use of a first pulley, a second pulley, and a belt, when the electrode cylinder rotates to drive the measuring wheel and the first rotating shaft, it can simultaneously drive the second rotating shaft and the input end of the encoder to rotate. This allows the encoder to detect the number of rotations of the measuring wheel, thereby measuring the electrode pressing and releasing depth. The use of multiple buffer mechanisms ensures that the measuring wheel is always pressed against the electrode cylinder, thus eliminating the influence of electrode cylinder vibration, weld beads, or pits on the surface on the measuring wheel. With the use of the clamping mechanism, belt slack is effectively prevented, ensuring that the belt remains taut throughout long-term use. This effectively prevents the belt from slipping on the first and second pulleys, thus not affecting the measurement accuracy and stability of the electrode pressing and releasing depth.

The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model provides an electrode pressing and discharging measurement device, such as... Figure 1-4 As shown, the electrode pressing and releasing measuring device includes: a housing 1, an inner housing 2 inside the housing 1, two fixing plates 3 on the inner housing 2, a first rotating shaft 4 rotatably mounted on the two fixing plates 3, a first pulley 9 fixedly sleeved on the first rotating shaft 4; a measuring wheel 5 fixedly sleeved on the first rotating shaft 4, anti-slip teeth 6 fixedly mounted on the measuring wheel 5, the anti-slip teeth 6 contacting the electrode cylinder 21; an encoder 8 fixedly mounted on the inner wall of the inner housing 2, a second rotating shaft 7 fixedly mounted on the input end of the encoder 8, a second pulley 10 fixedly sleeved on the second rotating shaft 7; a belt 11 sleeved on the first pulley 9 and the second pulley 10; multiple buffer mechanisms mounted on the housing 1 for buffering the inner housing 2; and a pressing mechanism assembled on the inner housing 2 for tensioning the belt 11.

[0024] In this embodiment, when the electrode cylinder 21 is raised and lowered, the measuring wheel 5 is driven to rotate by the anti-slip teeth 6. The measuring wheel 5 drives the first pulley 9 to rotate via the first rotating shaft 4. The first pulley 9 drives the second pulley 10 to rotate via the belt 11. The second pulley 10 drives the second rotating shaft 7 to rotate. The second rotating shaft 7 drives the input end of the encoder 8 to rotate. The encoder 8 can detect the number of rotations of the measuring wheel 5 and feed the data back to the DCS, thus realizing the measurement of electrode pressing depth. During the raising and lowering of the electrode cylinder 21, if the electrode cylinder 21 vibrates or the weld beads or pits on the surface affect the measuring wheel 5, multiple buffer mechanisms can keep the measuring wheel 5 pressed against the electrode cylinder 21, thereby eliminating the influence of the electrode cylinder 21 vibration, weld beads or pits on the surface on the measuring wheel 5. With the use of the clamping mechanism, the belt 11 can always be kept taut during long-term use, effectively preventing the belt 11 from slipping on the first pulley 9 and the second pulley 10, so as not to affect the measurement accuracy and stability of the electrode pressing depth.

[0025] In a further preferred embodiment of the present invention, the buffer mechanism includes: a groove 12 formed on the inner wall of the outer shell 1, a slide rod 13 fixedly installed on the inner wall of the groove 12, a first spring 14 slidably sleeved on the slide rod 13; and a slider 15 slidably installed on the slide rod 13, the slider 15 being fixedly connected to the inner shell 2.

[0026] In this embodiment, the buffer mechanism is used to buffer the inner shell 2. If the electrode cylinder 21 vibrates, or if weld beads or pits on the surface affect the measuring wheel 5, the measuring wheel 5 will move. The measuring wheel 5 will drive the inner shell 2 to move through the first rotating shaft 4 and the two fixed plates 3. The inner shell 2 will drive the slider 15 to slide on the slide rod 13. At this time, the slider 15 will also squeeze the first spring 14. When the pressure on the measuring wheel 5 is small, the first spring 14 will push the slider 15 and the inner shell 2 to move in opposite directions through elasticity, so that the measuring wheel 5 can always be pressed against the electrode cylinder 21.

[0027] In a further preferred embodiment of the present invention, the pressing mechanism includes: a plurality of second springs 16 fixedly installed on the inner wall of the inner shell 2; a pressure plate 17 fixedly installed on the plurality of second springs 16, a mounting bracket 18 fixedly installed on the pressure plate 17, a pressure wheel 19 rotatably installed on the mounting bracket 18, and the pressure wheel 19 contacting the belt 11.

[0028] In this embodiment, the clamping mechanism is used to tension the belt 11. When the belt 11 becomes loose due to long-term use, the second spring 16 will push the pressure plate 17 downward through its elasticity. The pressure plate 17 will drive the mounting bracket 18 and the pressure roller 19 to move downward until the pressure roller 19 presses tightly on the belt 11. In this way, the belt 11 can be effectively prevented from slipping on the first pulley 9 and the second pulley 10, so as not to affect the measurement accuracy and stability of the electrode pressing depth.

[0029] In a further preferred embodiment of the present invention, a plurality of limiting rods 20 are fixedly installed on the inner wall of the inner shell 2, and the plurality of limiting rods 20 are slidably connected to the pressure plate 17.

[0030] In this embodiment, the use of multiple limiting rods 20 ensures the stability of the pressure plate 17, mounting bracket 18, and pressure roller 19 during movement, preventing any displacement.

[0031] In a further preferred embodiment of this utility model, both fixing plates 3 are fixedly installed on the inner wall of the inner shell 2 by bolts, and both the outer shell 1 and the inner shell 2 are configured in a U-shape.

[0032] In this embodiment, the use of bolts not only makes it easy to fix the fixing plate 3 to the inner shell 2, but also makes it easy to remove the fixing plate 3 from the inner shell 2.

[0033] In a further preferred embodiment of this utility model, baffles are fixedly installed at the bottom ends of the plurality of limiting rods 20, and the plurality of baffles are used to block the pressure plate 17.

[0034] In this embodiment, the use of a baffle can effectively prevent the pressure plate 17 from detaching from the limit rod 20 when the belt 11 is replaced later.

[0035] In a further preferred embodiment of the present invention, the plurality of first springs 14 and the plurality of second springs 16 are all made of stainless steel, and one end of the second rotating shaft 7 is rotatably connected to the inner wall of the inner shell 2.

[0036] In this embodiment, the first spring 14 and the second spring 16, made of stainless steel, have good corrosion resistance and durability and are not easily damaged.

[0037] In summary, compared with related technologies, this solution, through the coordinated use of the first pulley 9, the second pulley 10, and the belt 11, can simultaneously drive the second shaft 7 and the input end of the encoder 8 to rotate when the electrode cylinder 21 rotates by lifting and lowering to drive the measuring wheel 5 and the first rotating shaft 4. This allows the encoder 8 to detect the number of rotations of the measuring wheel 5, thus achieving the measurement of the electrode pressing depth. The use of multiple buffer mechanisms ensures that the measuring wheel 5 always presses against the electrode cylinder 21, thereby eliminating the influence of electrode cylinder 21 vibration, weld beads, or pits on the surface on the measuring wheel 5. With the use of the clamping mechanism, the belt 11 can be effectively prevented from loosening, ensuring that the belt 11 remains taut throughout long-term use and effectively preventing the belt 11 from slipping on the first pulley 9 and the second pulley 10, thus not affecting the measurement accuracy and stability of the electrode pressing depth.
