DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0028] In the description of the present application: unless otherwise specified, the meaning of "multiple" is two or more. The terms "first", "second", "third" and the like in the present application are intended to distinguish the objects referred to, and do not have special technical connotations (for example, should not be understood as emphasizing importance or order, etc.). The expressions "include", "contain", "have" and the like also mean "not limited to" (some units, components, materials, steps, etc.).

[0029] Reference Figures 1-8 The present application discloses a covering agent feeding device suitable for tundish, comprising a connecting part 1 for connecting to an industrial six-axis robot, a connecting rod 2 connected to the other side of the connecting part 1, a hopper 3 connected to the end of the connecting rod 2 away from the connecting part 1 and used for accommodating bagged covering agent, a push plate 4 arranged in the hopper 3, and a driving assembly 5 connected to the connecting rod 2 and used for driving the push plate 4 to push the bagged covering agent in the hopper 3 out of the outlet of the hopper 3 to the tundish.

[0030] The covering agent feeding device is connected to the industrial six-axis robot through the connecting part 1, and the industrial six-axis robot moves according to the set path to accurately move the covering agent feeding device to the position where the covering agent needs to be added to the tundish. After reaching the specified position, the driving assembly 5 starts and pushes the push plate 4 to move forward, and the push plate 4 pushes the bagged covering agent in the hopper 3 out of the outlet of the hopper 3, and the bagged covering agent is pushed out and falls onto the surface of the molten steel in the tundish. The bagged covering agent releases the covering agent substance under the action of the high temperature of the molten steel and completes the covering operation. Through the covering agent feeding device, automatic feeding operation is realized, the risk of workers contacting the high-temperature molten steel area is avoided, the safety hazards and high labor intensity existing in the manual operation in the prior art are solved, and the accuracy and efficiency of the covering agent feeding are improved.

[0031] It should be noted that the industrial six-axis robot and the covering agent are both prior art. The industrial six-axis robot has six degrees of freedom and can complete precise operation in a narrow and complex space through its flexible movement capability, and is suitable for the covering agent feeding scene of the tundish. After the bagged covering agent falls into the molten steel in the tundish, the covering agent bag is quickly burned due to the high temperature of the molten steel, and the covering agent material is uniformly diffused on the surface of the molten steel to form an isolation layer, which plays a role in isolating oxygen, preventing the generation of oxidized inclusions, and maintaining the stability of the molten steel temperature.

[0032] The hopper 3 includes a first connecting plate 31 connected to one end of the connecting rod 2 and a bending piece 32 connected to the first connecting plate 31. The bending piece 32 includes a second connecting plate 321 connected to the first connecting plate 31 and two third connecting plates 322 integrally bent on both sides of the second connecting plate 321 and connected to the first connecting plate 31. The bending piece 32 and the first connecting plate 31 enclose a containing groove 33 for containing the bagged covering agent. An outlet is formed between the two third connecting plates 322 away from the connecting rod 2 to facilitate the push plate 4 to push the bagged covering agent out, so that the bagged covering agent falls into the tundish from the outlet;

[0033] The drive assembly 5 includes a drive piece 51 connected to the connecting rod 2 and a push rod 52 connected to the output shaft of the drive piece 51. The end of the push rod 52 away from the drive piece 51 is connected to the push plate 4 through the first connecting plate 31.

[0034] The drive piece 51 drives the push rod 52 to move back and forth through its output shaft. The push rod 52 is connected to the push plate 4 at one end and moves the push plate 4 with the driving of the drive piece 51. The push plate 4 starts from a position close to the first connecting plate 31 and pushes multiple bagged covering agents in the containing groove 33 to the outlet, and continues to push the bagged covering agents out of the outlet, so that they fall onto the surface of the molten steel in the tundish one by one.

[0035] Among them, the connecting part 1, the connecting rod 2 and the hopper 3 extend along a straight line in the length direction of the device, and the structure of the whole device is designed in an elongated type, so that it can adapt to the narrow space between the ladle and the tundish. When the space is limited, the device can smoothly complete the feeding operation of the covering agent, overcoming the limitation that the existing automatic device requires a larger height space, and realizing the precise automatic covering agent adding function in a small space.

[0036] The bending piece 32 is integrally bent with multiple folding edges 323 at the edge thereof. The multiple folding edges 323 correspond to the multiple edges of the edge of the bending piece 32 one by one, and the multiple folding edges 323 close to the first connecting plate 31 are each provided with multiple connecting holes matched with the first connecting plate 31.

[0037] The plurality of folded edges 323 near the first connecting plate 31 are connected to the first connecting plate 31 through the connecting holes formed therein, and can be connected to the first connecting plate 31 by using bolts or other fasteners. In addition, the folded edges 323 near the outlet of the hopper 3 cover the edges of the second connecting plate 321 and the third connecting plate 322, forming a smooth transition area, which can prevent the bagged covering agent from being scratched by the edges of the second connecting plate 321 or the third connecting plate 322 during the pushing process of the pushing plate 4, thereby avoiding problems such as breakage, leakage, or jamming of the bagged covering agent, and ensuring smooth delivery of the covering agent.

[0038] The driving member 51 is a power cylinder, the push rod 52 is connected to the output shaft of the power cylinder, and the connecting rod 2 is connected to the guide sleeve 6 for sleeving the push rod 52 at one end near the first connecting plate 31.

[0039] The guide sleeve 6 is located at one end near the first connecting plate 31 and is used to provide guidance and support for the push rod 52. When the push rod 52 reciprocates under the drive of the power cylinder, due to the length of the push rod 52, the end far from the power cylinder may be affected by external forces or its own torque due to lack of support, and is prone to deviation or vibration, thereby causing unstable movement trajectory and affecting the smooth movement of the pushing plate 4. By providing the guide sleeve 6, the deviation of the push rod 52 can be effectively limited, the rigidity of the push rod 52 can be enhanced, and the influence of lateral force or torque generated during movement on the push rod 52 can be reduced.

[0040] In some embodiments, the power cylinder can be an electric cylinder or a pneumatic cylinder.

[0041] The pushing plate 4 is connected to the guide rod 41, and the two ends of the guide rod 41 are respectively arranged on the folded edges 323 on the top of the two third connecting plates 322.

[0042] The guide rod 41 is arranged on the folded edges 323 on the top of the two third connecting plates 322 and is integrally connected with the pushing plate 4. When the pushing plate 4 moves under the drive of the push rod 52, the guide rod 41 can play a guiding and limiting role to ensure the smooth movement of the pushing plate 4 along the predetermined straight trajectory, and avoid rotation of the pushing plate 4 during movement. If the pushing plate 4 rotates, the edges of the pushing plate 4 may be stuck on the groove wall of the accommodating groove 33, causing movement obstruction or even damage to the pushing plate 4.

[0043] The connecting rod 2 is connected to the protective cover 511 wrapped outside the power cylinder. The workshop environment is usually complex, and there are dust, splashes, and other debris. The protective cover 511 can effectively block these debris from entering the interior of the power cylinder, reduce the damage of the workshop environment to the power cylinder, and prolong the service life of the power cylinder.

[0044] The connecting part 1 comprises a fourth connecting plate 11 connected to one end of the connecting rod 2, a flange interface 12 for connecting with the end of the industrial six-axis robot is connected to the side away from the connecting rod 2 of the fourth connecting plate 11, and the fourth connecting plate is provided with a threading hole 13 for connecting the power pipeline of the driving assembly 5.

[0045] The fourth connecting plate 11 is connected with the end of the industrial six-axis robot through the flange interface 12 thereof. The threading hole 13 provided on the fourth connecting plate 11 provides a passage for the power pipeline of the driving assembly 5 (such as an electric cylinder or a pneumatic cylinder), so that the power transmission device such as a cable or a gas pipe can smoothly pass through the threading hole 13.

[0046] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradictions). In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described. The embodiments not explicitly described are also considered to be within the scope of the present application.

[0047] The application is described in detail above through general description and specific embodiments. It should be understood that, based on the technical concept of the application, some conventional adjustments or further innovations can be made to the specific embodiments; however, as long as the technical concept of the application is not deviated, the technical solutions obtained by the conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
