Description

Technical Field

[0001] This utility model relates to the field of steelmaking technology in the metallurgical industry, and more specifically, to a desulfurization spray gun clamping device. Furthermore, it also relates to a desulfurization equipment including the aforementioned desulfurization spray gun clamping device. Background Technology

[0002] Existing common desulfurization methods include KR desulfurization and injection desulfurization. KR desulfurization is a mechanical stirring method for desulfurizing molten iron. During desulfurization in the ladle, a desulfurizing agent is added to the ladle surface, and a stirring head ensures thorough mixing and reaction between the agent and the molten iron. Injection desulfurization uses a desulfurization lance to inject the desulfurizing agent into the molten iron via a carrier gas. The carrier gas simultaneously acts as a stirrer, and the injected gas, desulfurizing agent, and molten iron mix together for desulfurization. Both methods suffer from the problem of insufficient mixing and reaction between the desulfurizing agent and molten iron. During operation, the desulfurization lance needs to be controlled to move up and down, inserting or removing itself from the molten iron, to achieve better mixing. However, existing desulfurization lances are mainly driven by a lifting device to move up and down on a lifting guide rail. During this movement or rotational stirring, the desulfurization lance is prone to irregular shaking or severe swaying.

[0003] In summary, how to provide a clamping device suitable for use with desulfurization spray guns, and which prevents irregular shaking or severe swaying of the desulfurization spray guns during lifting, moving, or rotating and stirring processes, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a desulfurization spray gun clamping device, which is suitable for use with desulfurization spray guns and can prevent irregular shaking or severe swaying of the desulfurization spray guns during lifting, moving, or rotating and stirring processes. Another purpose of this utility model is to provide desulfurization equipment including the above-mentioned desulfurization spray gun clamping device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A desulfurization spray gun clamping device includes:

[0007] A lifting vehicle that moves up and down along a lifting guide rail, the bottom of which is used to install desulfurization spray guns;

[0008] The mounting bracket is vertically positioned on the outside of the lifting vehicle;

[0009] An elastic clamping roller mechanism is vertically mounted on the mounting support, and the elastic clamping roller mechanism is used to elastically contact the lifting guide rail;

[0010] A fixed clamping roller mechanism is vertically mounted on the mounting support. The fixed clamping roller mechanism is used to engage with or move away from the lifting guide rail.

[0011] The elastic clamping roller mechanism and the fixed clamping roller mechanism are arranged in parallel to form a clamping member. The two clamping members are arranged in pairs and mirror-oriented with the lifting guide rail as the symmetrical plane. At least two pairs of clamping members are symmetrically arranged circumferentially on the outer side of the lifting vehicle.

[0012] In one embodiment, the fixed clamping roller mechanism includes an actuator, a transmission mechanism connected to the actuator, an eccentric rocker arm connected to the transmission mechanism, and a first guide wheel connected to the eccentric rocker arm. The actuator and the transmission mechanism are both mounted on the mounting support.

[0013] In one embodiment, the transmission mechanism includes a transmission shaft and a bearing. One end of the transmission shaft is connected to the actuator, and the other end of the transmission shaft passes through the bearing and is connected to the eccentric rocker arm. The bearing is provided in the mounting bracket.

[0014] In one embodiment, the fixed clamping roller mechanism includes a linear drive mechanism and a first guide wheel. The linear drive mechanism passes through the mounting bracket and is connected to the first guide wheel to drive the first guide wheel to extend toward or retract away from the lifting guide rail.

[0015] In one embodiment, the linear drive mechanism includes a hydraulic cylinder, a telescopic cylinder, or an electric cylinder.

[0016] In one embodiment, the elastic clamping roller mechanism includes an elastic element and a second guide wheel. One end of the elastic element is disposed on the mounting support, and the other end of the elastic element is connected to the second guide wheel, which rolls along the lifting guide rail.

[0017] In one embodiment, the elastic element includes a compression spring.

[0018] A desulfurization device, comprising the desulfurization spray gun clamping device described in any of the above claims.

[0019] When using the desulfurization nozzle clamping device provided by this utility model, the lifting car can be connected to the lifting device. The lifting car can move up and down under the drive of the lifting device. The lifting car can be equipped with a rotary drive device, which is connected to the desulfurization nozzle to drive the desulfurization nozzle to rotate. When the rotary drive device is not needed to drive the desulfurization nozzle to rotate (i.e., the desulfurization nozzle does not need to stir the molten iron), since the circumferential and radial forces on the lifting car are very small or non-existent, the lifting guide rail can be clamped by the elastic clamping roller mechanism alone to prevent the lifting car from shaking.

[0020] When the desulfurization nozzle needs to be rotated by the rotary drive device (i.e., the desulfurization nozzle needs to stir the molten iron), the circumferential and radial forces on the lifting car are large. Relying solely on the elastic clamping roller mechanism to clamp the lifting guide rail cannot prevent the lifting car from shaking. Therefore, it is necessary to control the operation of the fixed clamping roller mechanism (while the elastic clamping roller mechanism still clamps the lifting guide rail) so that the fixed clamping roller mechanism can press against the lifting guide rail and prevent irregular shaking when the desulfurization nozzle rotates.

[0021] Furthermore, both the first guide wheel of the fixed clamping roller mechanism and the second guide wheel of the elastic clamping roller mechanism can clamp the lifting guide rail. The lifting device (connected to the lifting vehicle and used to drive the lifting vehicle to move up and down) can still drive the lifting vehicle to rise and fall on the lifting guide rail (i.e., both the first and second guide wheels roll and rub against the lifting guide rail). Moreover, since at least two pairs of clamping members are symmetrically arranged circumferentially on the outer side of the lifting vehicle, each clamping member including both an elastic clamping roller mechanism and a fixed clamping roller mechanism, the desulfurization spray gun can be prevented from shaking or irregularly vibrating whether it is rotating or not.

[0022] In summary, the desulfurization spray gun clamping device provided by this utility model is suitable for use with desulfurization spray guns and can prevent irregular shaking or severe swaying of the desulfurization spray guns during lifting, moving or rotating and stirring.

[0023] In addition, this utility model also provides a desulfurization equipment including the above-mentioned desulfurization spray gun clamping device. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] The core of this utility model is to provide a desulfurization spray gun clamping device, which is suitable for use with desulfurization spray guns and can prevent irregular shaking or severe swaying of the desulfurization spray guns during lifting, moving, or rotating and stirring. Another core aspect of this utility model is to provide desulfurization equipment including the aforementioned desulfurization spray gun clamping device.

[0036] Please refer to Figures 1 to 6 This specific embodiment provides a desulfurization spray gun clamping device, including:

[0037] The lifting vehicle 1 moves up and down along the lifting guide rail 2, and the bottom of the lifting vehicle 1 is used to install the desulfurization spray gun 3.

[0038] Mounting support 41 is vertically mounted on the outside of the lifting vehicle 1;

[0039] The elastic clamping roller mechanism 4 is vertically mounted on the mounting support 41 and is used to elastically contact the lifting guide rail 2.

[0040] The fixed clamping roller mechanism 5 is vertically mounted on the mounting support 41. The fixed clamping roller mechanism 5 is used to engage with or move away from the lifting guide rail 2.

[0041] Among them, the elastic clamping roller mechanism 4 and the fixed clamping roller mechanism 5 are arranged in parallel to form a clamping component. The two clamping components are arranged in pairs and are mirror-oriented with the lifting guide rail 2 as the symmetrical plane. At least two pairs of clamping components are symmetrically arranged along the circumferential direction on the outer side of the lifting vehicle 1.

[0042] It should be noted that both the elastic clamping roller mechanism 4 and the fixed clamping roller mechanism 5 can be connected to the mounting support 41 by bolts, and the mounting support 41 can be fixedly connected to the main frame 6 of the lifting vehicle 1 by bolts. Each clamping component includes one elastic clamping roller mechanism 4 and one fixed clamping roller mechanism 5, and adjacent clamping components are arranged in pairs and mirror-oriented with the lifting guide rail 2 as the symmetrical plane. This effectively avoids jamming of the fixed clamping roller mechanism 5 when clamping the lifting guide rail 2 due to processing errors. Its structure is as follows: Figure 1 As shown, it includes 4 sets of clamping components, namely 8 elastic clamping roller mechanisms 4 and 8 fixed clamping roller mechanisms 5.

[0043] In practical applications, the shape, structure, size, material, and number of the lifting vehicle 1, the elastic clamping roller mechanism 4, and the fixed clamping roller mechanism 5 can be determined according to the actual situation and needs.

[0044] When using the desulfurization spray gun clamping device provided by this utility model, the lifting car 1 can be connected to the lifting device 7. The lifting car 1 can move up and down under the drive of the lifting device 7. The lifting car 1 can be equipped with a rotary drive device, which is connected to the desulfurization spray gun 3 to drive the desulfurization spray gun 3 to rotate. When the rotary drive device is not needed to drive the desulfurization spray gun 3 to rotate (i.e., the desulfurization spray gun 3 is not needed to stir the molten iron), since the circumferential and radial forces on the lifting car 1 are very small or non-existent, the lifting car 1 can avoid shaking by relying solely on the elastic clamping roller mechanism 4 to clamp the lifting guide rail 2.

[0045] When the desulfurization spray gun 3 needs to be rotated by the rotary drive device (i.e., the desulfurization spray gun 3 needs to stir the molten iron), the circumferential and radial forces on the lifting car 1 are large. Relying solely on the elastic clamping roller mechanism 4 to clamp the lifting guide rail 2 cannot prevent the lifting car 1 from shaking. Therefore, it is necessary to control the operation of the fixed clamping roller mechanism 5 (while the elastic clamping roller mechanism 4 still clamps the lifting guide rail 2) so as to use the fixed clamping roller mechanism 5 to press against the lifting guide rail 2 and prevent irregular shaking when the desulfurization spray gun 3 rotates.

[0046] Moreover, both the first guide wheel 54 of the fixed clamping roller mechanism 5 and the second guide wheel 43 of the elastic clamping roller mechanism 4 can clamp the lifting guide rail 22. The lifting device 7 (which is connected to the lifting vehicle 1 and is used to drive the lifting vehicle 1 to move up and down) can still drive the lifting vehicle 1 to rise and fall on the lifting guide rail 2 (that is, both the first guide wheel 54 and the second guide wheel 43 roll and rub against the lifting guide rail 22).

[0047] Furthermore, since the outer side of the lifting vehicle 1 is symmetrically provided with at least two pairs of clamping components along the circumferential direction, each clamping component includes an elastic clamping roller mechanism 4 and a fixed clamping roller mechanism 5, the desulfurization spray gun 3 can be made to not shake or vibrate irregularly whether it is rotating or not.

[0048] In summary, the desulfurization spray gun clamping device provided by this utility model is suitable for use with desulfurization spray guns and can prevent irregular shaking or severe swaying of the desulfurization spray guns during lifting, moving or rotating and stirring.

[0049] In one embodiment, such as Figures 1 to 3 As shown, the fixed clamping roller mechanism 5 includes an actuation mechanism 51, a transmission mechanism 52 connected to the actuation mechanism 51, an eccentric rocker arm 53 connected to the transmission mechanism 52, and a first guide wheel 54 connected to the eccentric rocker arm 53 (for example, the first guide wheel 54 is located at the end of the eccentric rocker arm 53). The actuation mechanism 51 and the transmission mechanism 52 are both located on the mounting support 41.

[0050] When it is necessary to control the fixed clamping roller mechanism 5 to press against the lifting guide rail 2, the actuator 51 can be controlled to run. The actuator 51 drives the transmission mechanism 52 to run synchronously. The transmission mechanism 52 can drive the eccentric swing rod 53 to swing, so that the first guide wheel 54 at the end of the eccentric swing rod 53 engages with the lifting guide rail 2 (the engagement here means that the first guide wheel 54 presses against the lifting guide rail 2 and the first guide wheel 54 rolls in contact with the lifting guide rail 2), so as to avoid shaking or irregular vibration when the desulfurization spray gun 3 rotates and stirs.

[0051] When it is not necessary to control the clamping roller mechanism 5 to press against the lifting guide rail 2, the actuator 51 can be controlled to run in reverse. The actuator 51 drives the transmission mechanism 52 to run in reverse. The transmission mechanism 52 can drive the eccentric swing rod 53 to swing in reverse, so that the first guide wheel 54 at the end of the eccentric swing rod 53 moves away from the lifting guide rail 2, and only the elastic clamping roller mechanism 4 and the lifting guide rail 2 are in elastic contact (only the second guide wheel 43 and the lifting guide rail 2 are in rolling contact), so as to avoid the phenomenon of shaking or irregular vibration when the desulfurization spray gun 3 is not rotating and stirring.

[0052] In one embodiment, the transmission mechanism 52 includes a transmission shaft and a bearing. One end of the transmission shaft is connected to the actuator 51, and the other end of the transmission shaft passes through the bearing and is connected to the eccentric rocker arm 53. The bearing is housed within the mounting bracket 41. For example, the actuator 51 can drive the transmission shaft to rotate. When the transmission shaft rotates, it can drive the eccentric rocker arm 53 to swing, thereby causing the first guide wheel 54 to swing with the eccentric rocker arm 53 to move closer to or further away from the lifting guide rail 2.

[0053] It should be added that, such as Figure 1As shown, the desulfurization spray gun 3 is not rotating at this time and may be in a lifting state. Usually, the desulfurization spray gun 3 stays in a certain place to perform rotating and stirring operations. At this time, there is no need to control the operation of the fixed clamping roller mechanism 5. That is, the lifting guide rail 2 can be clamped by the elastic clamping roller mechanism 4 to avoid the shaking phenomenon of the lifting vehicle 1 and the desulfurization spray gun 3 during the lifting process.

[0054] like Figure 2 As shown, the desulfurization spray gun 3 rotates counterclockwise at this time, meaning it is highly likely that the desulfurization spray gun 3 is stationary at a certain point performing counterclockwise rotational stirring. At this time, it is necessary to control the operation of the fixed clamping roller mechanism 5 (four fixed clamping roller mechanisms 5 extend and are distributed counterclockwise). This is because when the desulfurization spray gun 3 rotates and stirs, its rotational torque is relatively large, causing the spring of the elastic clamping roller mechanism 4 to experience large force and significant deformation. During the deformation of the elastic clamping roller mechanism 4, it is unavoidable that the lifting vehicle 1 and the desulfurization spray gun 3 will shake. Furthermore, the elastic force of the elastic clamping roller mechanism 4 alone is insufficient to support the rotational torque of the desulfurization spray gun 3. Therefore, it is necessary to... Figure 2 The fixed clamping roller mechanism 5 shown clamps the lifting guide rail 2. After the fixed clamping roller mechanism 5 is clamped against the lifting guide rail 2, it will not move again, which can effectively resist the torque of the desulfurization spray gun 3 and prevent the lifting vehicle 1 and the desulfurization spray gun 3 from shaking and irregular vibration. Of course, the first guide wheel 54 and the second guide wheel 43 are in rolling contact with the lifting guide rail 2, and can still drive the lifting vehicle 1 to move up and down under the action of the lifting device 7.

[0055] like Figure 3 As shown, the desulfurization spray gun 3 rotates clockwise at this time. At this time, it is necessary to control the operation of the fixed clamping roller mechanism 5 (four fixed clamping roller mechanisms 5 extend and are distributed clockwise) to clamp the lifting guide rail 2. After the fixed clamping roller mechanism 5 clamps the lifting guide rail 2, it will not move again, which can effectively resist the torque of the desulfurization spray gun 3 and prevent the lifting vehicle 1 and the desulfurization spray gun 3 from shaking and irregular vibration.

[0056] In one embodiment, such as Figures 4 to 6 As shown, the fixed clamping roller mechanism 5 includes a linear drive mechanism 55 and a first guide wheel 54. The linear drive mechanism 55 passes through the mounting support 41 and is connected to the first guide wheel 54 to drive the first guide wheel 54 to extend towards or retract away from the lifting guide rail 2.

[0057] When it is necessary to control the fixed clamping roller mechanism 5 to press against the lifting guide rail 2, the linear drive mechanism 55 can be controlled to run. The linear drive mechanism 55 drives the first guide wheel 54 to extend and move synchronously towards the lifting guide rail 2, until the first guide wheel 54 extends and engages with the lifting guide rail 2 (the engagement here refers to the rolling contact between the first guide wheel 54 and the lifting guide rail 2). When it is not necessary to control the fixed clamping roller mechanism 5 to press against the lifting guide rail 2, the linear drive mechanism 55 can be controlled to run in the opposite direction. The linear drive mechanism 55 drives the first guide wheel 54 to retract synchronously, so that the first guide wheel 54 moves away from the lifting guide rail 2, and only the elastic clamping roller mechanism 4 contacts the lifting guide rail 2, so as to avoid shaking or irregular vibration when the desulfurization spray gun 3 is not rotating and stirring.

[0058] In one embodiment, the linear drive mechanism 55 includes a hydraulic cylinder, a telescopic cylinder, or an electric cylinder. That is, the type and model of the linear drive mechanism 55 can be determined according to the actual situation and requirements during practical application.

[0059] In one embodiment, the elastic clamping roller mechanism 4 includes an elastic element 42 and a second guide wheel 43. One end of the elastic element 42 is mounted on the mounting support 41, and the other end of the elastic element 42 is connected to the second guide wheel 43, which rolls along the lifting guide rail 2. Regardless of whether the fixed clamping roller mechanism 5 is engaged with or disengaged from the lifting guide rail 2, the second guide wheel 43 of the elastic clamping roller mechanism 4 can elastically roll in contact with the lifting guide rail 2. This prevents the lifting vehicle 1 and the desulfurization spray gun 3 from shaking or irregularly vibrating when the desulfurization spray gun 3 is not rotating and stirring.

[0060] In one embodiment, the elastic element 42 includes a compression spring to ensure continuous contact between the second guide wheel 43 and the lifting guide rail 2, facilitating the rolling of the lifting vehicle 1 along the lifting guide rail 2. That is, the elastic clamping roller mechanism 4 and the fixed clamping roller mechanism 5 of this application are configured in cooperation, which not only stabilizes the lifting vehicle 1 in the working position but also prevents irregular shaking or severe swaying of the desulfurization spray gun 3 during lifting, moving, or rotating and stirring processes, and also has a buffering and vibration reduction function.

[0061] In addition to the desulfurization spray gun clamping device mentioned above, this utility model also provides a desulfurization equipment that includes the desulfurization spray gun clamping device disclosed in the above embodiments. For the structure of other parts of the desulfurization equipment, please refer to the prior art, which will not be repeated here.

[0062] It should be noted that, as Figure 7As shown, the desulfurization equipment may also include a main frame 6 welded from structural steel. The main frame 6 consists of two parts: columns and a top frame. The columns are generally quadrilateral frame structures, preferably made of I-beams or H-beams, but other profiles such as rectangular tubes can also be selected depending on the stress form. The top frame is welded from structural steel. The lifting guide rails 2 consist of 2-4 rails located inside the columns. The lifting vehicle 1 is located inside the main frame 6. According to the process operation requirements, the lifting vehicle 1 can rise or fall along the lifting guide rails 2 under the action of the lifting device 7.

[0063] It should also be noted that the lifting device 7 may include a drive motor 71, a reducer 72, a winch 73, a pulley block 74, and a tension detection device. The fixed pulleys of the pulley block 74 and the supports at the ends of the wire ropes are both mounted on the top frame of the main frame 6. The movable pulleys of the pulley block 74 are arranged in the lower middle part of the frame of the lifting vehicle 1. This helps to reduce the overall structural bulk of the device, improve the uniformity of force distribution and lateral force on the lifting vehicle 1, extend the lifespan of the lifting guide rail 2 and the lifting vehicle 1, and achieve the purpose of uniformly clamping the lifting guide rail 2 by the elastic clamping roller mechanism 4 and the fixed clamping roller mechanism 5. The tension detection device is used to detect whether the wire ropes are under uniform force or exhibit slack, ensuring that each wire rope is evenly stressed and preventing malfunctions of the lifting device 7.

[0064] It should be noted that the first guide wheel 54 and the second guide wheel 43 mentioned in this application are only distinguished by their different positions and do not have any order of precedence.

[0065] In addition, it should be noted that the orientation or positional relationship indicated by "forward" or "reverse" in this application is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the purpose of simplifying the description and making it easier to understand, and does 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. Therefore, it should not be construed as a limitation on this utility model.

Similar or identical parts between embodiments can be referred to interchangeably.
