Description

Technical Field

[0001] The utility model relates to the field of casting, in particular to a molten iron conveying protection device in the casting process. Background Art

[0002] Molten iron refers to high-temperature liquid iron, which is usually produced during the iron-making process. When steel products are processed, iron is melted at high temperature into molten iron and then poured into various molds to complete the production. The molten iron is hot and heavy, and is extremely dangerous. Therefore, when the molten iron is melted and transported, protective devices are required to prevent the molten iron from splashing during the input of the mold and causing injuries to workers.

[0003] The existing protective devices on the market are generally fixed and welded on both sides of the mold pouring position. Due to the fixed structure, the position cannot be raised or lowered and adjusted, and the entire line of sight is blocked, so it is impossible to observe the specific condition of the mold after pouring. Moreover, after the mold is transported to the designated position, when the molten iron is transported to the mold, the mold may be displaced due to the impact of the molten iron. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a molten iron conveying protection device during the casting process. By setting a blocking mechanism and a protection mechanism, the blocking mechanism is used to position and fix the mold to avoid displacement of the mold during pouring. At the same time, when the blocking mechanism is in operation, the lifting and lowering of the protection mechanism can be controlled in a linked manner to block the pouring and open the field of view after the pouring is completed.

[0005] In order to solve the above technical problems, the technical solution of the utility model is a molten iron conveying protection device in a casting process, comprising a roller conveyor, frames are fixedly installed on both sides of the middle top of the roller conveyor, the tops of the two frames are provided with blocking mechanisms, and the two ends of the two frames away from the blocking mechanism are provided with protection mechanisms;

[0006] Base frames are fixedly installed on both sides of the middle bottom end of the roller conveyor, support plates are fixedly installed on the top ends of the two base frames, a beam plate is fixedly installed between the top ends of the two support plates, and a material guide cylinder is fixedly installed in the middle of the beam plate.

[0007] As a further solution of the utility model: the blocking mechanism includes a mounting frame, an electric push rod and a blocking plate, the mounting frames are fixedly arranged at the top of the two frames, the electric push rods are fixedly arranged on both sides of the top of the mounting frames, the blocking plate is arranged near the bottom end of the mounting frame, and the output shafts of the two electric push rods are respectively arranged on both sides of the top of the blocking plate.

[0008] As a further solution of the utility model: a mounting seat is fixedly mounted on one side in the same direction of the middle part of the top end of the two mounting frames, and a positioning sensor is arranged in the middle part of the two mounting seats.

[0009] As a further solution of the present utility model: through grooves are respectively formed in both sides of the frame close to the baffle, and connecting pieces are fixedly installed on the outer sides of both sides of the baffle, and the two connecting pieces are respectively movably connected with the through grooves on both sides.

[0010] As a further solution of the present utility model: the protection mechanism includes a splash-proof plate, a ceramic lining plate and a heat insulation plate. Side grooves are respectively formed in one sides of the two frames close to the through grooves, and the splash-proof plates are movably installed between the side grooves on the same sides of the two frames. The ceramic lining plates are arranged on the same sides of the two splash-proof plates, and the heat insulation plates are arranged on the sides of the two splash-proof plates away from the ceramic lining plates.

[0011] As a further solution of the present utility model: strip-shaped grooves are respectively formed at the tops of both sides in the middle of the roller conveyor, and the bottom end of the splash-proof plate is movably connected with the strip-shaped grooves.

[0012] As a further solution of the present utility model: the connecting pieces arranged on both sides of the baffle pass through the through grooves and are fixedly connected with the splash-proof plate.

[0013] As a further solution of the present utility model: sliding strips are fixedly installed on the outer wall of the side of the splash-proof plate away from the connecting piece, sliding grooves are formed in the inner wall of the side of the frame away from the through groove, and the sliding strips are slidably connected with the sliding grooves.

[0014] Adopting the above technical solution: when the electric push rod drives the baffle to descend, the connecting pieces arranged on both sides of the baffle will drive the splash-proof plate to descend synchronously until the bottom end of the splash-proof plate is inserted into the strip-shaped groove. When the molten iron in the mold splashes, the ceramic lining plate on the side of the splash-proof plate close to the mold can be used for protection. Since the ceramic lining plate is made of ceramic material, it can provide stronger corrosion resistance and wear resistance, and the heat insulation plate arranged on the side of the splash-proof plate away from the ceramic lining plate is used for heat insulation and is used in cooperation with the blocking mechanism, and there is no need to additionally set up a lifting component for control. In this way, during transportation, protection can be carried out, and at the same time, the equipment cost can be reduced.

[0015] By setting the blocking mechanism, during use, the roller conveyor is started. After the roller conveyor is started, the mold is moved from one side of the roller conveyor to the middle position. At this time, the positions of the mold are confirmed by two positioning sensors in sequence. After the positioning sensors confirm the positions, the electric push rod is controlled to start. After the electric push rod starts, the baffle is controlled to descend until the two baffles block the outer sides of both sides of the mold. In this way, when the molten iron is input into the mold from the material guiding cylinder, the mold will not generate excessive displacement on the roller conveyor, and splashing of the molten iron caused by excessive shaking amplitude of the mold is avoided.

[0027] Embodiment 2

[0028] Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: a molten iron conveying and protecting device during casting, including a roller conveyor 1.

[0032] Specifically, when the electric push rod 302 drives the baffle 303 to descend, the connecting pieces 10 arranged on both sides of the baffle 303 will drive the splash guard 401 to descend synchronously until the bottom end of the splash guard 401 is inserted into the strip-shaped groove 11.
