Technical Field

[0001] This utility model relates to the field of bag-turning machine technology, and in particular to an automatic locking device and a bag-turning machine. Background Technology

[0002] A ladle turning machine is a specialized mechanical device that uses electricity or hydraulic power to slowly and controllably rotate and tilt a ladle around a horizontal axis, thereby pouring the high-temperature molten metal inside into a mold, ingot mold, or smelting furnace.

[0003] The ladle-turning arm, part of the ladle-turning machine, connects to the molten iron ladle to rotate it. To achieve bidirectional rotation of the ladle-turning arm, one side needs to be fixed to the frame, while the other side is separated, allowing the arm to rotate around its connection point with the frame. However, current locking mechanisms for the ladle-turning arm are complex, making the connection and disassembly between the arm and the frame complicated. Summary of the Invention

[0006] In some designs, the locking part has a first slot, and when the locking part and the flip arm are stopped and limited, the flip arm is embedded in the first slot.

[0007] In some designs, the frame is provided with a second slot for placing the bag-flipping arm. When the locking part is stopped and limited by the bag-flipping arm, the opening directions of the first slot and the second slot are offset.

[0008] In some designs, the drive assembly includes a telescopic rod and a connector, with the fixed end of the telescopic rod connected to the frame via the connector, and the piston end of the telescopic rod rotatably connected to the locking part.

[0009] In some designs, the connector includes a connecting ring and a connecting block, with the connecting ring fitted onto the fixed end of the telescopic rod; The connecting block is fixedly connected to the frame and rotatably connected to the connecting ring.

[0010] In some designs, the locking part has a first mounting groove, and the piston end of the telescopic rod extends into the first mounting groove and is rotatably connected to the locking part.

[0011] In some designs, the frame is provided with a second mounting slot, into which the connecting block is embedded.

[0012] Secondly, this application also discloses a bag-flipping machine, including a bag-flipping arm and the automatic locking device mentioned in the first aspect, wherein the bag-flipping arm is mounted on the machine frame.

[0013] The technical solution adopted in this utility model can achieve the following beneficial effects: The automatic locking device of this application, by rotating the locking part on the frame, decomposes the complex connection and separation actions into a simple single rotation operation.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0019] The following is in conjunction with the appendix Figures 1 to 5 The automatic locking device 100 and the bag flipping machine 200 provided in this application will be described in detail through specific embodiments and application scenarios.

[0020] Some embodiments of this application disclose an automatic locking device 100, including a frame 110, a locking part 120, and a drive assembly 130.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the locking part 120 is rotatably mounted on the frame 110. By rotating the locking part 120 on the frame 110, the complex connection and separation actions are broken down into a simple single rotation operation. The locking part 120 can quickly lock or disengage from the bag-flipping arm 210 by rotating itself, which greatly simplifies the operation process and improves the efficiency and convenience of connecting or disassembling the bag-flipping arm 210 with the frame 110.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly 130 is mounted on the frame 110 and connected to the locking part 120. The drive assembly 130 drives the locking part 120 to rotate, thereby stopping or separating the locking part 120 from the ladle-turning arm 210. By controlling the rotation of the locking part 120 through the drive assembly 130, the automatic separation or locking of the locking part 120 from the ladle-turning arm 210 is achieved, significantly improving the efficiency and accuracy of connection and separation, and fundamentally enhancing operational safety. This allows workers to stay away from the high-temperature radiation area of ​​the molten iron ladle, while ensuring the consistency and reliability of the locking force.

[0023] like Figure 2 and Figure 4 As shown, the locking part 120 has a first slot 121. When the locking part 120 and the ladle-turning arm 210 are stopped and limited, the ladle-turning arm 210 is embedded in the first slot 121. When the ladle-turning arm 210 is embedded in the first slot 121, the first slot 121 can effectively prevent the ladle-turning arm 210 from falling off the frame 110, thereby stably transmitting the huge turning torque and impact load to the frame 110 through surface contact, greatly enhancing the connection rigidity and fatigue resistance, thus ensuring the stability and safety of the molten iron ladle in heavy-load, high-frequency turning operations.

[0024] like Figure 2 and Figure 3 As shown, the frame 110 is provided with a second slot 111 for placing the bag-flipping arm 210. When the locking part 120 is stopped and limited by the bag-flipping arm 210, the opening directions of the first slot 121 and the second slot 111 are offset. By offsetting the opening directions of the first slot 121 and the second slot 111, a closed mechanical locking loop is formed. This structure can completely enclose and lock the bag-flipping arm 210 within the rigid space formed by the first slot 121 and the second slot 111, fundamentally preventing the bag-flipping arm 210 from loosening, falling out, or shifting under huge impacts or vibrations, greatly improving the safety and stability of the entire flipping operation.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly 130 includes a telescopic rod 131 and a connector 132. The fixed end of the telescopic rod 131 is connected to the frame 110 via the connector 132, and the piston end of the telescopic rod 131 is rotatably connected to the locking part 120. The connector 132 provides a mounting base for the telescopic rod 131 to be mounted on the frame 110. Furthermore, the connector 132 can adapt to the changes in the planar motion trajectory of the telescopic rod 131 when driving the locking part 120 to rotate, effectively avoiding motion interference between the connector 132 and the telescopic rod 131.

[0026] In this embodiment, the telescopic rod 131 is preferably a hydraulic rod.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the connector 132 includes a connecting ring 1321 and a connecting block 1322. The connecting ring 1321 is sleeved on the fixed end of the telescopic rod 131. The connecting block 1322 is fixedly connected to the frame 110 and rotatably connected to the connecting ring 1321. The rigid connection between the connecting block 1322 and the frame 110 provides a stable foundation. The sleeve connection between the connecting ring 1321 and the telescopic rod 131, and the rotatable connection with the connecting block 1322, forms a universal joint structure. This ensures that the drive assembly 130 can efficiently transmit the working power to the locking part 120 at any working angle. It also completely eliminates the harmful radial force and bending moment on the telescopic rod 131 caused by the mismatch of the mechanism's motion trajectory, thereby greatly improving the reliability, lifespan, and maintenance convenience of the entire drive system.

[0028] like Figure 4 As shown, the locking part 120 is provided with a first mounting groove 122, and the piston end of the telescopic rod 131 extends into the first mounting groove 122 and is rotatably connected to the locking part 120. By embedding and rotatably connecting the piston end of the telescopic rod 131 into the first mounting groove 122 of the locking part 120, the structural layout is optimized to make it more compact, significantly improving the reliability and durability of power transmission and reducing maintenance requirements.

[0029] The frame 110 is provided with a second mounting slot, into which the connecting block 1322 is embedded. The second mounting slot provides a mounting base for the connecting block 1322, directly transferring the enormous working force and impact load borne by the drive assembly 130 to the frame 110 body through a large-area contact, greatly enhancing structural stability and fatigue resistance. Simultaneously, this fitting method provides precise pre-positioning for the entire drive assembly, ensuring alignment accuracy with the locking part 120, simplifying the installation and commissioning process, and facilitating future maintenance and replacement.

[0030] Some embodiments of this application also disclose a bag-turning machine 200, such as Figure 1 and Figure 5 As shown, it includes a bag-flipping arm 210 and an automatic locking device 100 in the first aspect, with the bag-flipping arm 210 disposed on the frame 110.

[0031] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined.
