Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Please refer to Figures 1 to 5 , Figure 1 A schematic diagram of the structure of the oxygen-burning tube holder provided in an embodiment of the present application; Figure 2 A cross-sectional view of an oxygen tube holder provided in an embodiment of the present application;

[0037] Figure 4 A cross-sectional view of a pneumatic clamp and a sealing connection seat provided in an embodiment of the present application; Figure 5 A schematic diagram of the structure of the sleeve and quick connector provided in an embodiment of the present application.

[0038] Please refer to Figure 1 and Figure 2 The present application provides an oxygen pipe clamp, comprising a pneumatic clamp 1 for clamping the oxygen pipe 01 and a quick-connect seat 2 that can be quickly connected to a robot arm; a sleeve 4 is provided between the pneumatic clamp 1 and the quick-connect seat 2, and the pneumatic clamp 1 and the quick-connect seat 2 are respectively located at the two ends of the sleeve 4; the pneumatic clamp 1 has an air supply pipeline, which can provide compressed gas for the pneumatic clamp 1 so that the pneumatic clamp 1 can play a clamping role; the pneumatic clamp 1 is connected to the oxygen supply pipeline 3, which can be sealed and connected with the oxygen pipe 01, and is used to supply oxygen to the oxygen pipe 01; the oxygen supply pipeline 3 and the air supply pipeline both extend from the pneumatic clamp 1 to the quick-connect seat 2 in the sleeve 4; two groups of gas source interfaces 5 are provided on the outside of the quick-connect seat 2, and the oxygen supply pipeline 3 and the air supply pipeline are respectively connected to the above-mentioned two groups of gas source interfaces 5 on the outside of the sleeve 4.

[0039] The oxygen burning pipe clamp adopts a pneumatic clamp 1 to clamp the oxygen burning pipe 01, and adopts a quick connector 2 to connect the robot arm, so that the oxygen burning pipe 01 is installed on the robot arm, which is convenient for the operator to move the oxygen burning pipe 01 through the robot arm. For example, the operator can move the oxygen burning pipe 01 to the continuous casting platform of the steel plant through the robot arm, and use the robot arm to manipulate the oxygen burning pipe 01 to extend into the water outlet of the large bag, replacing manual operation. Among them, the quick connector 2 can be specifically set as follows Figure 1 Quick-change disc assembly shown.

[0040] The oxygen burning pipe clamp is provided with a sleeve 4 between the pneumatic clamp 1 and the quick-connect seat 2; the sleeve 4 can connect the pneumatic clamp 1 and the quick-connect seat 2, so that the two are separated by a certain distance, so as to avoid the robot arm and the oxygen burning pipe 01 being too close to each other when inserting the oxygen burning pipe 01 toward the water outlet of the large bag; the sleeve 4 can also be used as a pipeline layout channel for the oxygen supply pipeline 3 and the gas transmission pipeline, which can be referred to Figure 1 and Figure 2 The sleeve 4 surrounds most of the oxygen supply pipeline 3 and most of the gas pipeline, which can prevent the oxygen supply pipeline 3 and the gas pipeline from being directly exposed to the outside world, and avoid the oxygen supply pipeline 3 and the gas pipeline from being affected by the harsh working environment near the water outlet of the large bag when the oxygen burning pipe 01 is inserted into the water outlet of the large bag. In this embodiment, the oxygen supply pipeline 3 and the gas pipeline are not completely arranged in the sleeve 4. On the side close to the quick-connect seat 2, the oxygen supply pipeline 3 and the gas pipeline are both passed through the sleeve 4 and connected to the two sets of gas source interfaces 5 outside the quick-connect seat 2. This is convenient for monitoring and adjusting the gas path connection state of the oxygen supply pipeline 3 and the gas pipeline, and it also saves the need to set a gas source channel inside the quick-connect seat 2, which can simplify the quick-connect seat 2.

[0041] In summary, the oxygen burning tube clamp provided in the present application can realize the mechanical connection between the oxygen burning tube 01 and the robot arm, and realize the connection between the oxygen burning tube 01 and the gas source gas path, so that the operator can operate the robot arm far away from the continuous casting platform of the steel plant to extend the oxygen burning tube 01 into the water inlet of the large bag to realize oxygen burning drainage, replace manual oxygen burning drainage, and improve the operation safety of the operator; the oxygen burning tube clamp provided in the present application can provide effective protection for product components such as the quick connector 2, the robot arm, the oxygen supply pipeline 3 and the gas transmission pipeline, so as to ensure that these product components can operate reliably for a long time in the harsh working environment around the continuous casting platform of the steel plant.

[0042] The oxygen tube holder provided in the present application is further described below in conjunction with the accompanying drawings and implementation examples.

[0043] Please refer to Figure 1 , Figure 2 and Figure 4In some embodiments, in addition to the pneumatic clamp 1, the quick-connect seat 2 and the sleeve 4, the oxygen tube clamp provided in the present application also includes a sealing connection seat 6; the sealing connection seat 6 is arranged between the pneumatic clamp 1 and the sleeve 4; a sealing airway is arranged in the sealing connection seat 6, one end of the sealing airway is provided with a first interface 61 for the oxygen tube 01 to be sealed and inserted, and the other end of the sealing airway is provided with a second interface 62 that is sealed and connected to the oxygen supply pipeline 3. It can be seen that in this embodiment, when the pneumatic clamp 1 clamps the oxygen tube 01, the sealing connection seat 6 and the sealing airway therein can achieve a sealed connection between the oxygen tube 01 and the oxygen supply pipeline 3, ensure the gas path connection state between the oxygen tube 01 and the gas source, and ensure that the high-pressure oxygen will not leak at the entrance of the oxygen tube 01. In addition, since the oxygen-burning tube 01 is a disposable item, when the oxygen-burning tube 01 is inserted into the drain port of the large bag and the oxygen-burning drainage operation is performed, the sealing connection seat 6 can close the sealed airway, and the pneumatic clamp 1 opens to make the oxygen-burning tube 01 detach from the oxygen-burning tube clamp, thereby discarding the used oxygen-burning tube 01.

[0044] Generally, in the above embodiments, the sealed airway has only two passage openings, namely the first interface 61 and the second interface 62. When the first interface 61 is used to seal the oxygen burning pipe 01 and the second interface 62 is used to seal the oxygen supply pipeline 3, the oxygen in the gas source can enter the second interface 62 along the oxygen supply pipeline 3, flow from the second interface 62 to the first interface 61 in the sealed airway, and then flow out from the first interface 61 and flow to the oxygen burning pipe 01, and the oxygen burning pipe 01 guides the oxygen into the drain of the large bag. For the specific structural arrangement of the sealed connection seat 6 and its sealed airway, please refer to Figure 4 , you can also refer to the relevant designs in the prior art.

[0045] On the basis of the above embodiment, in order to improve the installation effect of the oxygen supply pipeline 3, the oxygen supply pipeline 3 may include a rigid tube 31 for connecting the second interface 62 and a flexible tube 32 for connecting the gas source, and the rigid tube 31 and the flexible tube 32 are connected to each other. The use of the rigid tube 31 to connect the second interface 62 of the sealing connection seat 6 is conducive to reducing the installation difficulty of the oxygen supply pipeline 3 and the sealing connection seat 6, and can also more reliably ensure the sealing connection effect of the oxygen supply pipeline 3 and the sealed airway; using the flexible tube 32 to connect the gas source interface 5 outside the quick-connect seat 2, and then connecting the gas source, can reduce the difficulty of pipeline wiring of the oxygen supply pipeline 3, and facilitate the specific shape structure of the sleeve 4 and the quick-connect seat 2 to adaptively adjust the oxygen supply pipeline 3 and the pipeline wiring path.

[0046] Typically, the rigid tube 31 can be set as a rigid metal tube, and the flexible tube 32 can be set as a metal hose. The rigid metal tube and the metal hose supply high-pressure oxygen to the oxygen-burning tube 01 through the sealing connection seat 6 .

[0047] For reference Figure 1 and Figure 3In the above embodiment, a first connection flange 7 may be provided between the adjacent ends of the sleeve 4 and the sealing connection seat 6; the aforementioned first connection flange 7 may include two flanges, one of which is provided at the end of the sleeve 4, and the other is provided at the end of the sealing connection seat 6; when the flange at the end of the sleeve 4 and the flange at the end of the sealing connection seat 6 are connected to each other, the rigid tube 31 passing through the sleeve 4 and the second interface 62 of the sealing connection seat 6 can be aligned and sealed. It can be seen that the first connection flange 7 can not only meet the fixed connection requirements of the sleeve 4 and the sealing connection seat 6, but also simplify the connection between the rigid tube 31 and the second interface 62, which is conducive to ensuring the installation effect of the rigid tube 31 and the second interface 62.

[0048] Usually, the tube wall of the sleeve 4 is provided with a first pipeline hole 41; the first pipeline hole 41 is adjacent to the quick-connect seat 2, and the flexible tube 32 can pass through the sleeve 4 from the first pipeline hole 41 and connect to the gas source interface 5 outside the quick-connect seat 2. Figure 1 and Figure 2 For example, the left end of the sleeve 4 is connected to the sealing connection seat 6, and the right end of the sleeve 4 is connected to the quick-connect seat 2. The first pipeline hole 41 is arranged on the tube wall of the sleeve 4 and is close to the right end of the sleeve 4. The rigid tube 31 and part of the flexible tube 32 pass through the sleeve 4, and the remaining flexible tube 32 passes through the sleeve 4 from the first pipeline hole 41 and extends toward the quick-connect seat 2, and can be connected to the air source interface 5 on the outside of the quick-connect seat 2.

[0049] On the basis of the above-mentioned embodiments, the oxygen-burning pipe clamp provided in the present application further includes a protective shell; the pneumatic clamp 1 and the sealing connection seat 6 are both integrated in the protective shell. In other words, the pneumatic clamp 1 and the sealing connection seat 6 are surrounded by the protective shell; wherein the protective shell is provided with an installation port for inserting the oxygen-burning pipe 01. This embodiment uses a protective shell to surround the pneumatic clamp 1 and the sealing connection seat 6, which can prevent the working environment of the oxygen-burning pipe 01 from affecting the structural performance of the pneumatic clamp 1 and the sealing connection seat 6. For example, the protective shell can prevent the material splashed from the large bag outlet from adhering to the movable parts of the pneumatic clamp 1, and the protective shell can prevent the high temperature environment of the large bag outlet from destroying the sealing performance of various seals in the sealing connection seat 6. In this embodiment, the protective shell is provided with an installation port, and the oxygen-burning pipe 01 can be inserted into the pneumatic clamp 1 and the sealing connection seat 6 from the installation port.

[0050] For reference Figure 1 and Figure 5 , the tube wall of the sleeve 4 may further be provided with a second pipeline hole 42; the second pipeline hole 42 is adjacent to the sealing connection seat 6, and the gas pipeline passes through the sleeve 4 from the second pipeline hole 42. In addition, the gas pipeline passes through the sleeve 4 from the first pipeline hole 41 to connect to the corresponding gas source interface 5. This embodiment provides a pipeline wiring method for the gas pipeline, which can realize the use of the sleeve 4 to guide and protect the gas pipeline, so that the gas pipeline is reliably connected to the gas source interface 5 provided on the outside of the quick-connect seat 2.

[0051] In the above embodiment, the protective shell surrounds part of the sleeve 4 and the second pipeline hole 42; the gas pipeline can be divided into three sections, the first section is in the protective shell and connected to the movable part of the pneumatic clamp 1, the second section passes through the sleeve 4 from the second pipeline hole 42, and is arranged along the length direction of the sleeve 4, and the third section passes through the sleeve 4 from the first pipeline hole 41 and extends toward the gas source interface 5 outside the quick connector 2, and is connected to the corresponding gas source interface 5. It can be seen that the protective shell and the sleeve 4 can provide protection and guidance to different parts of the gas pipeline, prevent the gas pipeline from being exposed to the harsh working environment of the oxygen burning pipe 01, and can also restrict the installation position of the gas pipeline, and prevent the gas pipeline from being hooked and entangled with other parts.

[0052] For reference Figure 2 and Figure 3 In some embodiments, the pneumatic clamp 1 may include a pneumatic claw 11 and a claw mounting seat 12 for realizing movable installation of the pneumatic claw 11; the claw mounting seat 12 and the sealing connection seat 6 are both encapsulated in a protective shell, and the pneumatic claw 11 passes through the protective shell from the installation port to facilitate grabbing the oxygen-burning tube 01.

[0053] For reference Figures 1 to 3 Usually, a second connection flange 9 can be provided between the pneumatic clamp 1 and the sealing connection seat 6; the pneumatic clamp 1 and the sealing connection seat 6 are connected to each other through the second connection flange 9. In combination with the foregoing, it can be seen that the sealing connection seat 6 and the sleeve 4 can be connected to each other through the first connection flange 7. It can be seen that for the sealing connection seat 6, the first connection flange 7 and the second connection flange 9 are provided at both ends thereof. In this embodiment, the first connection flange 7 and the second connection flange 9 are different in shape, which is convenient for the manufacturer or user to distinguish the installation angle of the sealing connection seat 6. Figure 1 As shown, a first connecting flange 7 is provided at the right end of the sealing connection seat 6, and the first connecting flange 7 is a circular flange; a second connecting flange 9 is provided at the left end of the sealing connection seat 6, and the second connecting flange 9 is a square flange.

[0054] In addition, please refer to Figure 1 and Figure 5 In some embodiments, a support seat 8 is provided on the outer periphery of the sleeve 4; the top of the support seat 8 is connected to the sleeve 4, and the bottom of the support seat 8 is provided with a positioning portion capable of positioning and cooperating with an external storage device. In this embodiment, the support seat 8 can support the oxygen-burning pipe clamp together with the external storage device, which is conducive to the orderly storage of the oxygen-burning pipe clamp and the convenience of the robot arm to grasp the oxygen-burning pipe clamp.
