Description
Technical Field
[0001] This utility model relates to the field of metallurgical machinery technology, and in particular to a hole-opening and plugging machine for metallurgical electric furnaces. Background Technology
[0002] Metallurgical electric furnaces are industrial furnaces used for heat treatment of materials or workpieces during metallurgical production. In the metallurgical process, opening and closing the furnace opening is a crucial step. Its purpose is to clear or block the taphole to ensure the smooth progress of the reaction inside the furnace and the safe maintenance of the furnace body. If the furnace opening is blocked or obstructed, it can lead to excessively high temperatures inside the furnace, or even serious consequences such as explosions. Therefore, an opening and closing machine is necessary.
[0003] Existing eye-opening and plugging machines have various configuration options. One type, the suspended eye-opening and plugging machine, is used to avoid occupying floor space during production. This type directly fixes the eye-opening and plugging components to a slide rail, which is then mounted on the traveling mechanism. However, this makes it difficult to adjust the spatial position of the eye-opening and plugging components. During long-term use, the machine is constantly aligned with the furnace opening. Over extended periods, the high temperatures emitted from the furnace opening can cause deformation, leading to inaccurate positioning, low production efficiency, and even equipment damage.
[0004] Therefore, there is a need for a hole-opening machine for metallurgical electric furnaces that can reduce the impact of high temperatures. Utility Model Content
[0005] The main purpose of this utility model is to provide a hole-opening and plugging machine for metallurgical electric furnaces, which aims to solve the problem that existing suspended hole-opening and plugging machines are easily affected by the high temperature of metallurgical furnaces.
[0006] To achieve the above objectives, this utility model proposes a hole-opening and plugging machine for metallurgical electric furnaces. The hole-opening and plugging machine is applied to metallurgical electric furnaces and includes: A suspension assembly, comprising a slide rail and a suspension, wherein the suspension is mounted on the periphery of the metallurgical electric furnace, and the slide rail is disposed at the bottom end of the suspension along the extending direction of the suspension; The suspension base includes a slide, a limiting bracket, and a drive wheel.

[0007] Preferably, the plugging assembly further includes a support frame, one end of which is fixedly connected to the rotating frame, and the other end of which is provided with a rotating shaft. The rotating shaft is rotatably connected to the barrel, and the axis of the rotating shaft is perpendicular to the axis of the metallurgical electric furnace. The support frame drives the barrel to rotate relative to the slide block through the rotating shaft.
[0008] Preferably, the eye-opening assembly further includes a deflection table, which includes a fixed end and a rotating end. The rotating end is rotatably connected to the bottom of the fixed end via a rotating shaft. The fixed end is fixedly connected to the slide, and the rotating end is fixedly connected to the frame.

[0011] Preferably, the plugging assembly further includes a slurry storage tank, which is disposed on the rotating frame at one end near the barrel. The slurry storage tank has a grouting port and a grouting outlet. The grouting port is disposed at the end away from the barrel, and the grouting outlet is connected to the hydraulic drive device.
[0012] Preferably, the suspension base is further provided with a lifting platform, which is located at the bottom of the slide and is movably connected to the slide through a kinematic pair. The lifting platform is spaced apart from the limiting frame, and the lifting platform is fixedly connected to the rotating frame and the machine frame.

[0019] like Figures 1-4 As shown, this utility model proposes a hole-opening and plugging machine 1000 for a metallurgical electric furnace, comprising: a suspension assembly 100, which includes a slide rail 110 and a suspension 120, the suspension 120 being mounted on the periphery of the metallurgical electric furnace, and the slide rail 110 being disposed at the bottom end of the suspension 120 along its extending direction; and a suspension base 200, which includes a slide block 210, a limiting frame 220, and a drive wheel 230, the slide block 210 being disposed at the bottom of the suspension 120 and slidably connected to the slide rail 110 via the drive wheel 230, and two limiting frames 220, which are respectively disposed on both sides of the slide block 210 and extend vertically upward, with the ends of the limiting frames 220 connected to... The suspension 120 is slidably connected; the plugging assembly 300 includes a rotating frame 310, a barrel 320, and a hydraulic drive device 330. The rotating frame 310 is located at the bottom end of the slide 210 and is rotatably connected to the slide 210. The barrel 320 and the hydraulic drive device 330 are sequentially connected to the rotating frame 310; the opening assembly 400 includes a frame 410, a drilling mechanism 420, and a drill rod 430. The frame 410 is located at the bottom end of the slide 210. The drilling mechanism 420 is located at the bottom end of the slide 210 through the frame 410 and is spaced apart from the rotating frame 310. The drilling mechanism 420 extends along the axial direction of the metallurgical electric furnace, and the drill rod 430 is coaxially connected to the drilling mechanism 420.
[0020] In this embodiment, the suspension 120 in the suspension assembly 100 is positioned corresponding to the top of the metallurgical electric furnace body and is kept at a safe distance from both the top of the metallurgical electric furnace and the furnace opening to prevent accidents to equipment or operators during the opening and plugging process. The suspension 120 has a groove-shaped structure with an open bottom. A slide rail 110 is located at the opening of the suspension 120 and extends along the length of the suspension 120. The suspension base 200 is provided with a slide block 210, and a drive wheel 230 is provided at the top of the slide block 210. It is understood that this utility model also includes a drive motor. After the drive motor is connected to an external power source, it transmits kinetic energy to the drive wheel 230. The drive wheel 230 reciprocates along the slide rail 110 to drive the suspension base 200 to move. The top of the suspension base 200 is also provided with two mirror-shaped limiting brackets 220. The two limiting brackets 220 extend vertically upward to the top of the suspension 120, and the ends of the two limiting brackets 220 are bent at opposite sides of the circumference of the suspension 120. The bent ends of the two limiting brackets 220 form a clamping grip to limit and fix the suspension base 200 relative to the suspension 120, so as to prevent the suspension base 200 from derailing or deforming.
[0021] In detail, the bottom of the suspension base 200 is also provided with an opening assembly 400 and a plugging assembly 300. The opening assembly 400 and the plugging assembly 300 are respectively set at the bottom of the suspension base 200 and spaced apart on both sides along the axial direction of the slide rail 110. The hydraulic drive device 330 and the barrel 320 on the plugging assembly 300 are connected to the suspension base 200 through a rotating frame 310. The rotating frame 310 can rotate relative to the slide 210. The rotation axis of the rotating frame 310 is perpendicular to the axis of the metallurgical electric furnace along the spatial z-axis. That is, the rotating frame 310 can drive the barrel 320 and the hydraulic drive device 330 to rotate. The hydraulic drive device 330 is used to pump the plugging material to the barrel 320, and then the barrel 320 sprays the plugging material onto the area to be plugged to complete the plugging operation.
[0022] More specifically, the drilling mechanism 420 and drill rod 430 in the eye-opening assembly 400 are connected to the slide block 210 via the frame 410. The drill rod 430 is disposed on the side of the drilling mechanism 420 near the metallurgical electric furnace and is coaxially connected to the drilling mechanism 420. The drilling mechanism 420 can drive the drill rod 430 toward the metallurgical electric furnace and reciprocate along the axis of the metallurgical electric furnace to perform drilling operations in the area to be opened.
[0023] In one embodiment, the plugging assembly 300 further includes a support frame 340, one end of which is fixedly connected to the rotating frame 310, and the other end of which is provided with a rotating shaft. The rotating shaft is rotatably connected to the barrel 320, and the axis of the rotating shaft is perpendicular to the axis of the metallurgical electric furnace. The support frame 340 drives the barrel 320 to rotate relative to the slide block 210 through the rotating shaft.
[0024] In this embodiment, the axis of the rotating shaft of the support frame 340 is perpendicular to the axis of the metallurgical electric furnace in the YZ plane of space. That is, the rotating shaft allows the barrel 320 to swing up and down relative to the metallurgical electric furnace. In other words, the barrel 320 has dual-axis mobility through the rotating frame 310, which increases the operating space of the barrel 320. It can be used to block multiple continuous metallurgical electric furnaces, and at the same time, it can be moved away from the metallurgical electric furnace during non-operation time to avoid being affected by continuous high heat.
[0025] In one embodiment, the eye-opening assembly 400 further includes a deflection table 440, which includes a fixed end and a rotating end. The rotating end is rotatably connected to the bottom of the fixed end via a rotating shaft. The fixed end is fixedly connected to the slide 210, and the rotating end is fixedly connected to the frame 410. The rotating end drives the drilling mechanism 420 to rotate relative to the slide 210.
[0026] In this embodiment, the rotating end of the deflection table 440 is connected to the top of the frame 410. A sliding pair is provided at the fixed end of the deflection table 440 near the metallurgical electric furnace, and a deflection shaft is provided at the fixed end away from the metallurgical electric furnace. The axis of the deflection shaft is perpendicular to the axis of the metallurgical electric furnace. The rotating end rotates relative to the fixed end through the coordinated action of the sliding pair and the deflection shaft. It is understood that the deflection table 440 is equipped with a controller and a deflection motor corresponding to the sliding pair. The operator controls the deflection angle of the deflection table 440 by controlling the start and stop of the deflection motor through the controller, thereby controlling the rotation of the frame 410 relative to the slide block 210. This allows the drilling mechanism 420 and the drill rod 430 to have a larger operating space during drilling operations and to be able to move away from the metallurgical electric furnace when not in operation, avoiding heat deformation.
[0027] In one embodiment, the eye-opening assembly 400 further includes an extension track 450, which is disposed at the bottom end of the frame 410 and slidably connected to the drilling mechanism 420. The drilling mechanism 420 is provided with pulleys corresponding to the extension track 450, and the extension track 450 extends along the axial direction of the metallurgical electric furnace.
[0028] In this embodiment, the extension track 450 is arranged on the frame 410 along the axial direction of the metallurgical electric furnace. A pulley is provided at the top of the drilling mechanism 420 corresponding to the extension track 450, and the pulley is slidably connected to the extension track 450. It is understood that an extension motor is provided on the drilling mechanism 420 corresponding to the pulley, providing kinetic energy to the pulley connection, causing the pulley to drive the drilling mechanism 420 to move closer to or further away from the metallurgical electric furnace along the extension track 450, thereby assisting the drill rod 430 in opening the borehole.
[0029] In one embodiment, the eye-opening assembly 400 further includes a rotary motor 460 and a brake 470. The rotary motor 460 is mounted on the frame 410 and is located near one end of the drilling mechanism 420. The rotary motor 460 is rotatably connected to the drill rod 430. There are multiple brakes 470, which are spaced apart around the circumference of the drill rod 430, and all of the multiple brakes 470 are connected to the rotary motor 460.
[0030] In this embodiment, a rotary motor 460 is mounted on the frame 410 near the drilling mechanism 420 and connected to the drill rod 430 via a gear set, driving the drill rod 430 to rotate. This rotation increases the efficiency of the drilling operation. The invention also includes three brakes 470 around the drill rod 430, evenly spaced to brake it after the drilling operation is completed.
[0031] In one embodiment, the plugging assembly 300 further includes a slurry storage tank 350, which is disposed on the rotating frame 310 at one end near the barrel 320. The slurry storage tank 350 is provided with a grouting port and a grouting outlet. The grouting port is disposed at the end away from the barrel 320, and the grouting outlet is connected to the hydraulic drive device 330.
[0032] In this embodiment, the slurry storage tank 350 is used to store the plugging mud supplied by an external liquid source. A grouting port is provided at the end away from the barrel 320. The plugging mud from the external liquid source enters the slurry storage tank 350 through the grouting port, and then the plugging mud is pumped to the barrel 320 by the hydraulic drive device 330. After being guided, the plugging mud is sprayed from the barrel 320 onto the area to be plugged, thereby realizing the plugging operation.
[0033] In one embodiment, the suspension base 200 is further provided with a lifting platform 240, which is located at the bottom of the slide 210 and is movably connected to the slide 210 through a kinematic pair. The lifting platform 240 is spaced apart from the limiting frame 220, and the lifting platform 240 is fixedly connected to the rotating frame 310 and the frame 410.
[0034] In this embodiment, the lifting platform 240 is disposed at the bottom of the slide 210. The kinematic pair consists of four piston rods evenly spaced apart. Through the coordinated operation of the piston rods, the lifting platform 240 can move vertically relative to the slide 210 to assist in the alignment of the eye opening component 400 or the eye plugging component 300 and increase the multi-scenario applicability of this utility model.
[0035] In one embodiment, the limiting frame 220 further includes a limiting slider 221, which is disposed at the end of the limiting frame 220. The suspension 120 is provided with a limiting groove corresponding to the limiting slider 221. The limiting groove is disposed along the extension direction of the suspension 120, and the limiting slider 221 is slidably connected to the limiting groove.
[0036] In this embodiment, four limiting sliders 221 are provided at the end of the limiting frame 220, and the ends of the limiting frames 220 on both sides form a group of eight limiting sliders 221. The limiting sliders 221 are connected to the limiting frame 220 by bolts. The limiting sliders 221 are slidably connected to the limiting groove provided at the top of the suspension 120 and extending along the length of the suspension 120, so as to provide a limiting function for the suspension base 200, prevent the suspension base 200 from derailing, and also share the pressure at the end of the drive wheel 230, extending the equipment life. This invention features a suspension assembly mounted around the periphery of a metallurgical electric furnace, with drive wheels and sliding rails cooperating to move the suspension base, which in turn moves the eye-opening and eye-closing assemblies. Operators can adjust the spatial position of the eye-opening and eye-closing assemblies according to actual needs during operation. During non-working hours, the eye-opening and eye-closing assemblies can be moved away from the metallurgical electric furnace to avoid the risk of metal deformation caused by continuous contact with high temperatures. This adjustment increases equipment lifespan and improves production efficiency. The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
