Description

Technical Field

[0001] This utility model relates to smelting equipment, and in particular to a ladle covering device. Background Technology

[0002] After converter smelting or refining, the molten steel in the ladle needs to be kept warm to reduce temperature drop caused by heat loss. Covering the ladle achieves energy conservation and consumption reduction. The ladle must be covered during waiting, transportation, pouring, hot repair, and slag removal. Automatic ladle covering and uncovering are achieved by aligning the ladle with the process flow at the process operation positions in converters, LF furnaces, etc.

[0003] Currently, existing ladle capping devices generally use hooks to add or remove the cap. If the hook and the ladle cap are not aligned, the capping or uncapping process cannot be completed, thus affecting production. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a ladle capping device that enables rapid capping and uncapping of ladle, thereby improving production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ladle capping device includes a support frame, a displacement detection hydraulic cylinder, a suction cup bracket, a lifting rope, and an electromagnetic chuck. The displacement detection hydraulic cylinder is connected to the top of the support frame, and the bottom end of the piston rod of the displacement detection hydraulic cylinder is connected to the suction cup bracket. Support rods are evenly distributed on the suction cup bracket, and the lifting rope is connected to the bottom middle part of the suction cup bracket. The electromagnetic chuck is connected to the outer end of the support rods and the lifting rope. The displacement detection hydraulic cylinder and the electromagnetic chuck are controlled by a PLC controller.

[0007] The suction cup bracket includes a vertical rod, and a support rod is connected to the outer periphery of the vertical rod. The support rod is horizontally arranged in three equal parts.

[0008] The piston rod of the displacement detection hydraulic cylinder is connected to the upright of the suction cup bracket via a flange.

[0009] The support rod is connected to the electromagnetic chuck via a connecting rod.

[0010] When the suspension rope is in a suspended state, the electromagnetic chuck connected to it is lower than the electromagnetic chuck connected to the support rod.

[0011] The suspension rope is a flexible metal rope.

[0012] Compared with existing technologies, the beneficial effects of this utility model are:

[0013] This invention enables rapid ladle loading and unloading operations. The displacement detection hydraulic cylinder provides accurate positioning, while the electromagnetic chuck quickly picks up the ladle cover, reducing loading and unloading time. The electromagnetic chuck on the suspension rope in the middle of the chuck bracket contacts the cover first, providing positioning and ensuring reliable adhesion. This prevents accidents caused by incomplete adhesion from the outer electromagnetic chucks. Furthermore, the suspension rope is flexible, ensuring it does not interfere with the descent of other electromagnetic chucks. Attached Figure Description

[0017] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] A ladle capping device includes a support frame 1, a displacement detection hydraulic cylinder 2, a suction cup bracket, a lifting rope 3, and an electromagnetic chuck 4. The top of the support frame 1 is connected to the displacement detection hydraulic cylinder 2, the bottom end of the piston rod of the displacement detection hydraulic cylinder 2 is connected to the suction cup bracket, support rods 5 are evenly distributed on the suction cup bracket, the bottom middle part of the suction cup bracket is connected to the lifting rope 3, and the outer end of the support rods 5 and the lifting rope are connected to the electromagnetic chuck 4. The displacement detection hydraulic cylinder 2 and the electromagnetic chuck 4 are controlled by a PLC controller.

[0020] The suction cup bracket includes a vertical rod 6, and a support rod 5 is connected to the outer periphery of the vertical rod 6. The support rod 5 is horizontally arranged in three equal parts.

[0021] The piston rod of the displacement detection hydraulic cylinder 2 is connected to the upright rod 6 of the suction cup bracket via flange 7.

[0022] The support rod 5 is connected to the electromagnetic chuck 4 via the connecting rod 7.

[0023] When the suspension rope 3 is in a suspended state, the electromagnetic chuck 4 connected to it is lower than the electromagnetic chuck 4 connected to the support rod 5.

[0024] The suspension rope 3 is a flexible metal rope.

[0025] The working process of the above device:

[0026] 1) Lid opening: When the ladle reaches the position below the lid-adding device, the displacement detection hydraulic cylinder is activated, and the electromagnetic chuck descends to the ready position. When the ladle reaches the position where the lid needs to be opened, the displacement detection hydraulic cylinder is activated again, and the electromagnetic chuck continues to descend. The electromagnetic chuck on the hoisting rope contacts the ladle lid first, and then the electromagnetic chuck on the support rod contacts the ladle lid at the same time. The electromagnetic chuck is energized and attracts the ladle lid. At this time, the piston rod of the displacement detection hydraulic cylinder retracts, lifting the ladle lid and separating the ladle lid from the ladle.

[0027] 2) Covering: When the ladle moves to the position below the covering device, the displacement detection hydraulic cylinder is activated, and the electromagnetic chuck pulls the ladle cover down to the ready position. When the ladle moves to the position where the cover needs to be applied, the displacement detection hydraulic cylinder is activated again, the ladle cover descends and locks onto the ladle, the electromagnetic chuck is de-energized, the piston rod of the displacement detection hydraulic cylinder retracts, and the electromagnetic chuck separates from the ladle cover.
