Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a casting pouring ladle cover opening and closing protection device. Background Art

[0002] Casting ladle cover usually refers to the structure installed on the top of the ladle during the metal casting process. The purpose is to prevent hot liquid metal from splashing out or causing harm to the operator during the opening process, while also ensuring the smooth progress of the pouring process.

[0003] In the prior art, the conventional cover plate adopts a structure of flipping to one side to open. In actual use, when the cover plate is flipped to open, the cover plate will block the operator's sight to a certain extent, increasing the operator's blind spot. At the same time, the upward opening method will cause the cover plate to easily block the filling equipment when the molten iron is poured into the casting ladle from one side, resulting in the operating position of the equipment for filling the molten iron being restricted.

[0004] As a result, most casting ladles are no longer equipped with covers. Although this design facilitates the casting operation, the temperature of the molten iron inside the casting ladle without a cover drops rapidly during use, and the molten iron will always be in contact with the air, which can easily cause the quality of the casting to deteriorate. At the same time, during the casting process, the molten iron inside the casting ladle is prone to splashing due to shaking, causing burns to the operator. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the traditional cover plate in the prior art is opened by flipping to one side. In actual use, when the cover plate is flipped open, the cover plate will block the operator's working line of sight to a certain extent, increasing the operator's blind spot. At the same time, the upward opening method will cause the cover plate to easily block the filling equipment when molten iron is poured into the casting ladle from one side, resulting in the problem that the working position of the equipment for filling molten iron is restricted. A casting casting ladle cover opening and closing protection device is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a casting casting ladle cover opening and closing protection device, including a casting ladle body, a cover plate mechanism is fixedly connected to the upper part of the casting ladle body, the cover plate mechanism includes a No. 1 fixed plate, the No. 1 fixed plate is fixedly connected to the surface of the casting ladle body, and the upper part of the No. 1 fixed plate is fixedly connected to a gear box, a transmission rod is rotatably connected inside the gear box, the top of the transmission rod is fixedly connected to a connecting plate, the upper part of the connecting plate is fixedly connected to a hydraulic cylinder, the upper part of the hydraulic cylinder is fixedly connected to a No. 2 fixed plate, the side of the No. 2 fixed plate is fixedly connected to a cover plate body, and the cover plate body is fitted with the upper part of the casting ladle body.
