[0026] like Figure 1 As shown, Figure 1 This is a schematic diagram showing the usage status of the dual-track mixed iron car tank opening slag removal device.

[0027] The dual-track mixed iron car mouth slag cleaning device of this utility model includes a cutter head 1, a three-coordinate slag cleaning unit 2, a guide rail platform 3, a hydraulic power system 4, and a control system 5. The cutter head 1 and the three-coordinate slag cleaning unit 2 are connected by a transmission. The three-coordinate slag cleaning unit 2 is mounted on the guide rail platform 3. The hydraulic power system 4 is connected to the cutter head 1 and the three-coordinate slag cleaning unit 2 to provide power. The control system 5 is connected to the hydraulic power system 4 and the three-coordinate slag cleaning unit 2. The three-coordinate slag cleaning unit 2 moves horizontally and linearly on the guide rail platform 3. The three-coordinate slag cleaning unit 2 drives the cutter head 1 to move vertically and horizontally, thereby realizing the three-way adjustment of the cutter head 1 to facilitate the relative movement of the cutter head 1 and the torpedo car mouth and the slag cleaning operation.

[0028] This invention is not only safe and easy to operate, with stable operation quality and low investment cost, meeting actual on-site needs and high work efficiency, but also greatly reduces maintenance costs and downtime losses, providing a guarantee for rational production organization. At the same time, it provides a scientific reference for the online processing of other large workpieces.

[0029] Example 2

[0030] like Figure 2 As shown, Figure 2 This is a structural view of the cutter head unit 1; the cutter head unit 1 includes a connecting seat 11, a hydraulic motor 12, and a rotating cutter holder 13. The connecting seat 11 is fixedly connected to the three-coordinate slag cleaning unit 2. The hydraulic motor 12 is mounted on the connecting seat 11 and is drivenly connected to the rotating cutter holder 13. The hydraulic motor 12 can drive the rotating cutter holder 13 to rotate, thereby realizing the slag cleaning operation of the rotating cutter holder 13 on the mouth of the torpedo tank car.

[0031] The cutter head 1 is connected to the three-coordinate cleaning unit 2 via the connecting seat 11. The three-coordinate cleaning unit 2 drives the cutter head 1 to move vertically to extend into the mouth of the torpedo tank car. The hydraulic motor 12 drives the rotating cutter holder 13 to rotate to perform the cleaning operation.

[0032] The hydraulic motor 12 is connected to the hydraulic power system 4 to achieve corresponding control.

[0033] like Figure 3 and Figure 4 As shown, Figure 3 This is a three-dimensional structural view of the three-coordinate cleaning unit; Figure 4 This is a top view of the structure of the three-coordinate cleaning unit.

[0034] The three-coordinate cleaning unit 2 includes a main support 21, a connecting support 28, and an adjusting plate 29. The main support 21 is a horizontally arranged rectangular frame structure. The adjusting plate 29 is disposed inside the main support 21 and has an adjusting hole. The connecting support 28 is disposed inside the adjusting hole. Both sides of the adjusting plate 29 are movably connected by horizontal sliders and horizontal slide rails. The connecting support 28 is movably connected to the adjusting plate 29 by rollers. The adjusting plate 29 moves horizontally linearly within the main support 21 along the extension direction of the horizontal slide rail. The connecting support 28 moves horizontally linearly within the adjusting hole by rollers. The cutter head 1 is movably connected to the connecting support 28, thereby enabling horizontal adjustment of the cutter head 1.

[0035] The three-coordinate cleaning unit 2 also includes a first hydraulic cylinder 27 and a second hydraulic cylinder 22. One end of the first hydraulic cylinder 27 is fixedly mounted on the adjusting plate 29, and the other end is fixedly connected to the connecting bracket 28. Thus, the extension and retraction of the first hydraulic cylinder 27 drives the connecting bracket 28 to move horizontally in the adjusting hole. One end of the second hydraulic cylinder 22 is fixedly mounted on the main bracket 21, and the other end is fixedly connected to the adjusting plate 29. Thus, the extension and retraction of the second hydraulic cylinder 22 drives the adjusting plate 29 to move horizontally in the main bracket 21 along the extension direction of the horizontal slide rail. The extension and retraction directions of the first hydraulic cylinder 27 and the second hydraulic cylinder 22 are perpendicular.

[0036] Generally, the connecting bracket 28 includes a fixed bracket and a movable bracket. The fixed bracket is movably connected to the main bracket 21 via the rollers. The movable bracket is fixedly connected to the cutter head 1. The fixed bracket and the movable bracket are movably connected via a vertical slider and a vertical slide rail, so that the movable bracket can drive the cutter head 1 to move vertically in a straight line along the extension direction of the vertical slide rail.

[0037] The three-coordinate cleaning unit 2 also includes a third hydraulic cylinder 23, which is fixedly mounted on the fixed frame. The output shaft of the third hydraulic cylinder 23 is vertically mounted and fixedly connected to the cutter head unit 1. The cutter head unit 1 can be driven to move linearly in the vertical direction by the third hydraulic cylinder 23.

[0038] The first hydraulic cylinder 27, the second hydraulic cylinder 22, and the third hydraulic cylinder 23 are connected to the hydraulic power system 4 to achieve corresponding control.

[0039] like Figure 5 As shown, Figure 5It is a structural view of the guide rail platform; the guide rail platform 3 includes guide rails 31 and a guide rail bracket 32, and the two guide rails 31 are arranged in parallel and symmetrically at the upper end of the guide rail bracket 32; the three-coordinate slag cleaning part 2 further includes a pulley 24 and a motor 25; the pulley 24 is fixedly arranged on the main bracket 21, and the main bracket 21 is movably connected to the corresponding guide rail 31 through the pulley 24, and the motor 25 is传动连接 with one pulley 24, and the motor 25 drives the pulley 24 to move linearly along the corresponding guide rail 31.

[0040] The motor 25 is connected to the control system 5 to achieve corresponding control. Generally, a pulley 24 is arranged at each of the four right angles of the main bracket 21, so as to achieve stable movement on the two guide rails 31.

[0041] Preferably, a track clamping device 26 is further arranged on the three-coordinate slag cleaning part 2. The track clamping device 26 is arranged on the main bracket 21. The track clamping device 26 fixes the position of the three-coordinate slag cleaning part 2 on the guide rail 31 to achieve the relative position fixation of the cutter head part 1 and the torpedo ladle car.

[0042] The guide rail bracket 32 is supported and fixed by a number of platform legs 321. The platform legs 321 are arranged in a straight line.

[0043] Preferably, there are three platform legs 321. Each platform leg 321 has four feet. The three platform legs 321 are distributed on both sides and in the middle of the guide rail bracket 32 to provide support for the guide rail platform 3. The parallel distribution of the three platform legs 321 forms a double-track hot metal mixer channel.

[0044] The top of the guide rail bracket 32 is rectangular as a whole in a top view, showing a "mouth" shape in a top view, with a hollow in the middle, and the surrounding is enclosed by a top plate of a steel plate to form a rectangular frame structure. The guide rails 31 are distributed in parallel on the upper surface of the top plate and are fixed by welding along the inner edge.

[0045] As Figure 6 shown, Figure 6 It is a control schematic diagram of the double-track hot metal mixer ladle mouth slag cleaning device; the hydraulic power system 4 includes a hydraulic station 41. The first hydraulic cylinder 27, the second hydraulic cylinder 22, and the third hydraulic cylinder 23 are connected to the hydraulic station 41 through hydraulic pipelines; the controller of the track clamping device 26 and the solenoid valve 42 on the hydraulic pipeline are respectively connected to the control system 5 through circuits.

[0046] The motor 25 drives the pulley 24 to move, moving the cutter head 1 above the mixing car's opening. The track clamping device 26 stops the three-coordinate slag cleaning unit 2, completing the positioning of the opening. By controlling the opening and closing of the solenoid valve 42, the first hydraulic cylinder 27, the second hydraulic cylinder 22, and the third hydraulic cylinder 23 are controlled to move the cutter head 1 to the opening, completing the cleaning of the first mixing car's opening.

[0047] In the three-coordinate slag cleaning unit 2, the first hydraulic cylinder 27 drives the cutter head 1 to move longitudinally, the second hydraulic cylinder 22 drives the cutter head 1 to move laterally, and the third hydraulic cylinder 23 drives the cutter head 1 to move vertically, so that the cutter head 1 is inserted into the tank opening. The hydraulic motor 12 works to drive the cutter head 1 to rotate and perform slag cleaning operation.

[0048] After the first mixed iron car's tank opening is cleaned, the hydraulic cylinder stroke control of the first hydraulic cylinder 27, the second hydraulic cylinder 22, and the third hydraulic cylinder 23 is achieved by controlling the opening and closing of the solenoid valve 42. This moves the cutter head 1 upwards back to its initial position. Simultaneously, the track clamping device 26 closes, and the motor 25 drives the pulley 24 to move, moving the three-coordinate cleaning unit 2 above the second mixed iron car's tank opening. The track clamping device 26 then opens, and the three-coordinate cleaning unit 2 stops moving. The cleaning of the second mixed iron car's tank opening is repeated by controlling the movement of the hydraulic cylinders through the solenoid valve 42. After cleaning is completed, the cleaning device returns to its initial position through the control system, completing the cleaning process.

Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
