Description

Technical Field

[0001] This utility model belongs to the field of robotic arms, specifically relating to an automated disassembly and assembly mechanism for a sliding plate slag-blocking device. Background Technology

[0002] Converter steelmaking is an oxidation process. In the later stages of smelting, while reducing carbon in the molten steel, a large amount of excess oxygen remains. Furthermore, the need for dephosphorization results in highly oxidizing slag, which increases deoxidation costs and negatively impacts the cleanliness of the molten steel in subsequent processes. With the increasing production of automotive steel, the development of specialty steels, and rising market demands for quality, higher requirements are being placed on steel quality. Minimizing the amount of slag added to the converter is a significant challenge in converter steelmaking. Various slag-blocking technologies have been widely adopted, including slag-blocking balls, slag-blocking cones (or slag-blocking cones), and sliding plate slag-blocking. In recent years, with the maturity and stability of sliding plate slag-blocking technology, steel mills have begun to adopt it for slag blocking during the converter tapping process. Although this increases refractory material costs, its high efficiency, low failure rate, and excellent slag-blocking effect have led to its gradual acceptance by steel mills.

[0003] In the process of manufacturing slag-blocking slide plates, refractory materials need to be poured into molds and shaped by vibration or compaction, followed by drying and sintering. Due to the special shape of the slag-blocking slide plates, conventional clamps cannot hold them well and they are prone to falling off during movement. At the same time, the temperature in the slag-blocking slide plate manufacturing workshop is high, and conventional clamps cannot adapt well. Summary of the Invention

[0004] To address the problem that conventional grippers cannot effectively hold the slag-blocking slide plate and are prone to detachment during movement, this invention proposes an automated disassembly and assembly mechanism for the slag-blocking slide plate to solve the aforementioned issues.

[0005] An automated disassembly and assembly mechanism for a sliding plate slag barrier includes a base plate, on which a first connecting block and a linear motor are mounted. The linear motors are symmetrically distributed along the central axis of the base plate. Through holes are formed on the surface of the base plate, each corresponding to a linear motor. The through holes completely penetrate the base plate. A heat-insulating sleeve is fitted into the through holes to prevent heat conduction to the linear motors and improve their service life. A clamping mechanism is installed at the bottom of the base plate, with the clamping mechanism corresponding to the position of each through hole.

[0006] The clamping mechanism includes a telescopic rod and a positioning block. The telescopic rod is located below the through hole. A fixing claw is movably connected to the bottom of the positioning block. One end of the heat insulation sleeve is connected to the output end of a linear motor. The other end of the heat insulation sleeve is connected to one end of the telescopic rod. The other end of the telescopic rod is connected to a second connecting block. One end of the second connecting block is connected to the telescopic rod, and the other end of the second connecting block is connected to the fixing claw.

[0007] The telescopic rod has a groove at its bottom, and a through hole is formed inside the groove. The through hole extends through both sides of the groove and is fitted with a fixing pin. The second connecting block has fixing holes at both ends, and the fixing hole and the fixing pin at the end closest to the telescopic rod are fitted together for fixation.

[0008] The fixing claw is L-shaped, with a first groove at one end and a hook at the other end. A through hole is provided on the inner surface of the first groove, penetrating the inner surface of the first groove. One end of the second connecting block is fitted into the first groove, and a fixing rod is fitted into the through hole, with the fixing rod penetrating both the through hole and the fixing hole.

[0009] When a sliding plate slag-blocking automated disassembly and assembly mechanism is in operation, the entire clamping assembly is moved under the control of a robotic arm. The robotic arm moves the jaws to the working position, the linear motor starts, and the output end moves downward, causing the heat insulation sleeve to move downward, which in turn moves the second connecting block connected to the telescopic rod downward. The downward movement of the second connecting block causes one end of the fixed jaw to move downward, and the middle position of the fixed jaw extends into the positioning block and is movably connected through the positioning rod. When one end of the fixed jaw moves downward, the hook at the other end of the fixed jaw moves away from the bottom plate, thus opening. At this time, the robotic arm moves downward so that the bottom plate is aligned with the slag-blocking sliding plate. Then, the linear motor starts, and the output end moves upward, causing the heat insulation sleeve to move upward, which in turn moves the second connecting block connected to the telescopic rod upward. The upward movement of the second connecting block causes one end of the fixed jaw to move upward, which in turn moves the other end of the fixed jaw towards the bottom plate, so that the hook contacts the slag-blocking sliding plate and hooks onto the lower surface of the slag-blocking sliding plate, thus completing the clamping.

[0010] The hook claw has anti-slip texture on its surface; it makes better contact with the slag-blocking slide plate surface when clamping and picking up, preventing slippage.

[0011] Multiple positioning blocks are provided, and the positioning blocks are located at the four corners of the base plate. The surface of the positioning block is provided with a positioning groove, and a fixing claw is movably engaged in the positioning groove. A positioning pin is engaged in the positioning groove, and the positioning pin passes through the fixing positioning groove and the fixing claw.

[0012] The linear motor is bolted to the upper surface of the base plate, facilitating maintenance and replacement.

[0013] The first connecting block is connected to the robotic arm.

[0014] The base plate is made of high-temperature resistant metal material, and the surface of the base plate is heat-insulated to avoid the high-temperature working environment from affecting the normal operation of the device and to improve the life of the device.

[0015] Compared with the prior art, the present invention has the following beneficial effects;

[0016] This utility model designs a claw that better fits the shape of the slag-blocking slide plate. The base plate is similar in shape to the slag-blocking slide plate, and a clamping mechanism is designed at the four corners. Together with the L-shaped fixing claw, it hooks the slag-blocking slide plate during clamping, avoiding the problems of unstable clamping and inconvenience of conventional fixing claws, thus improving clamping efficiency. Furthermore, high-temperature resistant metal materials are used and heat insulation treatment is applied to avoid the high-temperature working environment affecting the normal operation of the device and to extend the life of the device.

[0030] The clamping mechanism includes a telescopic rod 7 and a positioning block 5. The telescopic rod 7 is located below the through hole.

The other end of the heat insulation sleeve is connected to one end of the telescopic rod 7. The other end of the telescopic rod 7 is connected to a second connecting block 4. One end of the second connecting block 4 is connected to the telescopic rod 7, and the other end of the second connecting block 4 is connected to the fixing claw 6.

[0031] The telescopic rod 7 has a groove at its bottom, and a through hole is provided inside the groove. The through hole extends through both sides of the groove and is fitted with a fixing pin 701. The second connecting block 4 has fixing holes at both ends. The fixing hole and the fixing pin 701 at the end closest to the telescopic rod 7 are fitted together for fixation.

[0032] The fixing claw 6 is L-shaped. One end of the fixing claw 6 is provided with a first groove 601, and the other end of the fixing claw 6 is provided with a hook 602. The inner surface of the first groove 601 is provided with a through hole, which penetrates the inner surface of the first groove 601. One end of the second connecting block 4 is fitted into the first groove 601. A fixing rod is fitted into the through hole, and the fixing rod penetrates the through hole and the fixing hole.

[0033] The surface of the hook 602 is provided with anti-slip texture.

[0034] Multiple positioning blocks 5 are provided. The positioning blocks 5 are located at the four corners of the base plate 1.

[0038] Example 2

[0039] like Figure 1-7 As shown; the working process of an automated disassembly and assembly mechanism for a sliding plate slag barrier; when the automated disassembly and assembly mechanism for a sliding plate slag barrier is working, the entire clamping assembly is moved by a robotic arm. The robotic arm moves the clamping claw to the working position, the linear motor 2 starts, and the output end moves downward, causing the heat insulation sleeve to move downward, which in turn drives the second connecting block 4 connected to the telescopic rod 7 to move downward. The downward movement of the second connecting block 4 causes one end of the fixed claw 6 to move downward. The middle position of the fixed claw 6 extends into the interior of the positioning block 5 and is movably connected through the positioning rod. When one end of the fixed claw 6 moves downward, the hook 602 at the other end of the fixed claw 6 moves away from the bottom plate 1, thereby opening.
