Description

Technical Field

[0001] The utility model relates to the field of casting equipment, in particular to a casting system for a lower ring casting of a pumped storage water turbine. Background Art

[0002] The lower ring of the turbine is a component that connects the runner and is used to ensure the normal connection and use of the runner. In the production and preparation process of the lower ring of the turbine, since the lower ring of the turbine is a large casting, large casting equipment is required, which requires the use of a ladle, which is used to hold the molten metal and pour the molten metal into the mold for molding.

[0003] When the existing ladle is in use, the ladle body is transported by a hanging frame and a connecting frame. The hanging frame and the connecting frame are connected only by bolts. There is no anti-falling structure at the lower end of the hanging frame that passes through the connecting frame. When the bolt breaks, the connecting frame will fall off the hanging frame, which will cause the ladle body to fall off. There are certain safety hazards in use. In addition, in the ladle, in addition to using a motor to drive the ladle body to rotate, a wheel can also be used for manual operation. The wheel is generally installed on a manual shaft by welding, which is not easy to disassemble. In some plug-in wheels, there is no limiting structure after the wheel is installed. The wheel is easy to fall off from the manual shaft when in use, and the stability is relatively poor. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 4 As shown, a pouring system for the lower ring casting of a pumped-storage turbine comprises a ladle 1, the ladle 1 is connected to a connecting frame 2, and a hanging frame 3 is provided at the upper end of the connecting frame 2, an electric driving seat 5 is installed at the lower end of the connecting frame 2, the lower end of the hanging frame 3 passes through the connecting frame 2, and an anti-slip structure 4 is installed at the lower end of the hanging frame 3, a manual wheel 7 is installed on the electric driving seat 5 through a transmission structure 6, the ladle 1 is rotatably connected to the connecting frame 2, and the connecting frame 2 and the hanging frame 3 are fixed together by fixing screws, a drain port 8 is provided on the ladle 1, and a limit frame matched with the connecting frame 2 is installed on the ladle 1.

[0019] When using the pouring equipment to pour the lower ring of the turbine, the ladle 1 is suspended by the connecting frame 2 and the hanging frame 3. An anti-drop structure 4 is provided at the lower end of the hanging frame 3. A manual wheel 7 is installed on the electric drive seat 5 at the lower end of the connecting frame 2 through a transmission structure 6. The molten metal is contained in the ladle 1. In the initial state, the ladle 1 is firmly arranged relative to the connecting frame 2 due to the effect of the limiting frame. In this way, when the ladle 1 is suspended and transported, the shaking of the ladle 1 will not occur, causing the molten metal to leak. When the ladle 1 is transported to the mold, the limiting frame is opened. After starting the electric drive seat 5, the ladle 1 rotates and tilts on the connecting frame 2, and the molten metal in the ladle 1 flows into the mold through the drain port 8. The mold is used to form the lower ring of the turbine. After the pouring is completed, the ladle 1 can be reset. When necessary, the manual wheel 7 can be used for driving. The operation mode is diversified. During the use of the entire equipment, if the bolts connecting the suspension frame 3 and the connecting frame 2 are broken, the anti-detachment structure 4 plays a safety role at this time, ensuring that the connecting frame 2 will not fall off the suspension frame 3, thereby ensuring the safety of use.

[0020] Through the above implementation scheme, the anti-slip structure 4 includes an anti-slip plate 402 and a side plate 403, the anti-slip plate 402 is connected to the lower end of the suspension frame 3 through the side plate 403, the anti-slip structure 4 also includes a threaded hole 401 and a connecting bolt 404, the threaded hole 401 is opened at the lower end of the suspension frame 3, a round hole is provided on the side plate 403, the connecting bolt 404 passes through the round hole on the side plate 403, and the end of the connecting bolt 404 is threadedly connected in the threaded hole 401, the transmission structure 6 includes a transmission rod 601, a plug rod 603 and a plug sleeve 605, the plug rod 603 is installed on the transmission rod 601, and the plug sleeve 605 is arranged on the manual wheel 7, the transmission structure 6 also includes a baffle 602, a connecting hole 604 and a limit assembly 606, the baffle 602 is fixed at the place where the transmission rod 601 and the plug rod 603 are connected, the connecting hole 604 is opened on the plug rod 603, the plug sleeve 605 is sleeved on the plug rod 603, and the limit assembly Component 606 is connected to the connecting hole 604, and the limiting component 606 includes a limiting rod 6061, a threaded joint 6062 and a hexagonal groove 6063. The threaded joint 6062 is fixed to the lower end of the limiting rod 6061, and the threaded joint 6062 is threadedly connected to the connecting hole 604, and the hexagonal groove 6063 is opened at the upper end of the limiting rod 6061. By arranging an anti-drop structure 4 at the lower end of the suspension frame 3, when the bolt connecting the suspension frame 3 and the connecting frame 2 is broken, the anti-drop structure 4 has an anti-drop effect, ensuring that the connecting frame 2 and the suspension frame 3 are still connected together, avoiding the falling of the ladle 1, and improving the safety of use. The transmission structure 6 is used to install the manual wheel 7, which is convenient for disassembling the manual wheel 7 for storage. At the same time, a limiting component 606 is arranged on the insertion rod 603 to limit the manual wheel 7 and avoid the falling of the manual wheel 7, thereby ensuring relative stability in use, simple structure and excellent use effect.

[0021] When installing the anti-slip structure 4, fit the anti-slip plate 402 to the lower end of the suspension bracket 3, so that the round hole on the side plate 403 is aligned with the threaded hole 401, and the end of the connecting bolt 404 is passed through the round hole and connected with the threaded hole 401, so as to complete the installation of the anti-slip structure 4. When installing the manual wheel 7 through the transmission structure 6, connect the plug sleeve 605 on the manual wheel 7 to the plug rod 603 until the plug sleeve 605 contacts the baffle 602, and then put the limit rod 6061 on the plug rod 603, and use a tool to rotate the limit rod 6061 through the hexagonal groove 6063 so that the threaded joint 60 62 is screwed into the connecting hole 604, thereby installing the limit component 606. After the limit component 606 is installed, it can be used. When manually driven, the manual wheel 7 drives the plug sleeve 605, the plug rod 603 and the transmission rod 601 to rotate, and the transmission rod 601 drives the internal structure of the electric drive seat 5 to operate, thereby achieving the purpose of rotating the casting ladle 1. During the manual operation, the limit component 606 plays a limiting role to prevent the plug sleeve 605 from falling off, thereby ensuring the stability of use. When needed, the limit component 606 can be quickly disassembled and the manual wheel 7 can be removed, and the operation is convenient.
