Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0030] Refer to Figure 1 - Figure 3 An embodiment provided by the utility model: a kind of ladle blow argon automatic connecting device, including blow argon female joint 1 and blow argon male joint 2, blow argon female joint 1 bottom is equipped with blow argon male joint 2, blow argon female joint 1 includes bottom plate 101, bottom plate 101 bottom is equipped with joint 103, joint 103 inside is equipped with valve block 105, joint 103 bottom is equipped with guide sleeve 106 by bolt nut 110, joint 103 inside is provided with airtight assembly;
[0031] Airtight assembly includes end cover 109, end cover 109 outside is installed in joint 103 inside, end cover 109 inner wall is fixedly connected with spring one 108, spring one 108 bottom end is fixedly connected with ball core 107.
[0032] Specifically, in the ladle argon blowing operation, the argon blowing female connector 1 and the argon blowing male connector 2 play a role together to realize automatic connection and argon transmission. In the argon blowing female connector 1, the bottom plate 101 is mainly used to stably install the argon blowing female connector 1 at the bottom of the ladle, providing a mounting base and support for the entire female connector. The connector 103, as a key component, is an important channel for argon to enter and exit the ladle, and also provides installation space for other internal components. The valve block 105 can control the flow of argon. When the device is not connected, the valve block 105 can prevent argon leakage. After connection, it ensures that argon flows along the specified path. The guide sleeve 106 is installed at the bottom of the connector 103 through the bolt and nut 110. During the docking process of the argon blowing female connector 1 and the argon blowing male connector 2, the guide sleeve 106 provides precise guidance for the insertion of the argon blowing male connector 2, ensuring that the two can be quickly and accurately connected. The air-tight assembly is crucial to ensure the sealing of argon transmission. The end cover 109 is installed inside the connector 103. It not only plays a role in fixing the spring 108, but also protects the internal spring 108 and the ball core 107. The spring 108 keeps the ball core 107 in a specific position, closes the argon passage, and prevents argon leakage. During docking, the ball core 107 is extruded by the argon blowing male connector 2, compressing the spring 108 to move upwards, opening the argon passage. At the same time, under the action of the spring force of the spring 108, the ball core 107 can tightly cooperate with the argon blowing male connector 2 to achieve air tightness, ensuring that argon will not leak during transmission.
[0033] Referring to Figure 1 - Figure 3 The argon blowing male connector 2 includes a gas guide column 201, the top of which is arranged inside the guide sleeve 106. The spring upper seat 202 is installed on the outside of the gas guide column 201. The spring bottom seat 204 is arranged on the outside of the gas guide column 201. The spring 203 is sleeved on the outside of the gas guide column 201. The stop ring 205 is arranged at the bottom of the spring bottom seat 204.
[0034] Specifically, in the ladle argon blowing automatic connection device, the components of the argon blowing male connector 2 work closely together and play a key role in the connection and argon blowing process. The gas guide column 201 serves as a direct channel for argon transmission, responsible for introducing external argon into the device and delivering it to the argon blowing female connector 1, and then into the ladle, ensuring that argon can smoothly reach the ladle to participate in the argon blowing operation. The spring upper seat 202 is used to fix one end of the spring two 203, providing a support point for the spring two 203, allowing it to remain stable during operation and exert its proper elastic function. The spring two 203 is a key component that ensures the tight connection of the argon blowing male connector 2 and the argon blowing female connector 1. When the argon blowing male connector 2 is connected to the argon blowing female connector 1, the spring two 203 is compressed to generate a spring force. This spring force can push the argon blowing male connector 2 upwards, making it tightly fit with the argon blowing female connector 1 and enhancing the connection stability between them, ensuring that there is no looseness during the argon blowing process, while also assisting in achieving better airtightness to prevent argon leakage. The spring base 204 is used to fix the other end of the spring two 203, which cooperates with the spring upper seat 202 to securely install the spring two 203 on the gas guide column 201, ensuring the normal operation of the spring two 203 and bearing the pressure generated by the spring two 203, and transmitting the pressure to the components below. The retaining ring 205 is used to prevent the spring base 204 from falling off the gas guide column 201, serving as a limiting and fixing function.
[0035] Referring to Figure 1 - Figure 3 The gas guide column 201 is externally threaded with a nut 206, a positioning block 102 is provided between the bottom plate 101 and the connector 103, an end cap 104 is installed on the outside of the connector 103, the spring two 203 is externally provided between the spring base 204 and the spring upper seat 202, the retaining ring 205 is externally provided on the gas guide column 201, and the bottom of the retaining ring 205 is provided on the top of the nut 206.
[0036] Specifically, the nut 206 mainly adjusts and fixes the relative position of each component on the argon blowing male joint 2 by tightening or loosening, the positioning block 102 is used for accurately guiding the butt joint position of the argon blowing female joint 1 and the argon blowing male joint 2 when the ladle is lifted to the ladle car for butt joint, deviation in the butt joint process can be avoided, the gas guide column 201 can be accurately inserted into the guide sleeve 106, the accuracy and efficiency of automatic connection are improved, the whole argon blowing operation is ensured to be carried out smoothly, the end cap 104 plays a role in protecting the internal structure of the joint 103, the spring two 203 is a key component for providing elastic force, when the argon blowing male joint 2 is butt jointed with the argon blowing female joint 1, the spring two 203 is compressed to generate elastic force, the check ring 205 plays a double role of limiting and fixing, is sleeved on the gas guide column 201, can prevent the spring base 204 from sliding downward along the gas guide column 201, and ensure that the elastic assembly composed of the spring base 204, the spring two 203 and the spring upper seat 202 is stable in position on the gas guide column 201, and at the same time, the bottom thereof is in contact with the top of the nut 206, cooperates with the nut 206 to further fix each component, and enhances the stability of the whole structure of the argon blowing male joint 2, and guarantees the reliability of the argon blowing process.
[0037] Working principle: when working, the crown block lifts the ladle provided with the argon blowing female joint 1, so that the argon blowing female joint 1 approaches the argon blowing male joint 2 on the ladle car, under the action of the positioning block 102, the argon blowing female joint 1 is accurately positioned with the argon blowing male joint 2, when the ladle is placed on the ladle car, the gas guide column 201 of the argon blowing male joint 2 is inserted into the guide sleeve 106 of the argon blowing female joint 1, along with the insertion action, the argon blowing male joint 2 extrudes the ball core 107 in the argon blowing female joint 1 upward, the ball core 107 compresses the spring one 108 to move upward, the valve block 105 is opened, the argon gas passage is opened, at the same time, the spring two 203 on the argon blowing male joint 2 is compressed, the elastic force generated makes the argon blowing male joint 2 closely fit with the argon blowing female joint 1, the top of the gas guide column 201 of the argon blowing male joint 2 cooperates with the ball core 107 and other components to realize airtightness, so that the argon gas cannot leak, at this time, the argon gas enters from the gas guide column 201 of the argon blowing male joint 2, passes through the opened valve block 105, enters the ladle through the joint 103 of the argon blowing female joint 1, and the ladle argon blowing operation is completed.
