Description

Technical Field

[0001] The utility model belongs to the technical field of continuous steel casting and steelmaking, in particular to a two-in-one gripper device for replacing a side sealing plate and a flow distributor for thin strip continuous casting. Background Art

[0002] In the thin strip continuous casting unit process, the molten steel stored in the ladle flows into the tundish through the nozzle, and then flows from the tundish through the nozzle into the multi-stage flow distributor or rectifier ladle, and then flows into the molten pool formed by the crystallization rollers and side sealing plates through the flow distributor.

[0003] In actual applications, since the side sealing plates and flow distributors are consumable parts made of refractory materials, they need to be replaced regularly. At the same time, due to the production process requirements, the side sealing plates and flow distributors need to be preheated to about 1200°C. Therefore, a multi-axis robot and a baking heating box with a replacement side sealing plate and a flow distributor gripper device are provided on the transmission side and the operation side of the crystallization roller area of ​​the thin strip continuous casting unit casting machine. However, the current technical solution adopts that the replacement side sealing plate and the flow distributor gripper device exist separately, or are set upside down. When in use, they need to be swapped up and down or used separately, which increases replacement and use time. There is a risk of long installation time and high hidden dangers. It cannot meet the use of both the side sealing plate and the flow distributor gripper device at the same time, which is inconvenient to use and has low efficiency. Therefore, the present technical solution proposes a two-in-one gripper device for replacing side sealing plates and flow distributors for thin strip continuous casting suitable for the above-mentioned scenario.

[0007] The bottom of the bearing box is hinged with cross-arranged side sealing plate clamps for clamping the side sealing plates and two sets of flow distributor clamps for clamping the flow distributor; the two sets of flow distributor clamps are symmetrically installed on both sides of the side sealing plate clamps;

[0008] A set of side sealing plate clamp cylinders for lifting the side sealing plate clamps and two sets of flow distributor clamp cylinders for lifting the flow distributor clamps are vertically installed in the bearing box; the ends of the side sealing plate clamp cylinders are connected to the cross position of the side sealing plate clamps through a connecting shaft structure; the ends of the flow distributor clamp cylinders are connected to the cross position of the flow distributor clamps through a connecting shaft structure;

[0009] The side sealing plate clamp cylinder, the flow distributor clamp cylinder and the bottom of the bearing box are connected through a hinge structure with a transverse limiting hole. When the side sealing plate clamp cylinder and the flow distributor clamp cylinder are lifted or lowered, the side sealing plate clamp and the flow distributor clamp are driven to clamp or release.

[0010] Furthermore, the cross position of the side sealing plate clamp and the cross position of the flow distributor clamp are the axis of the movable rotating shaft.

[0011] Furthermore, the stroke distance of the side sealing plate clamp cylinder is greater than the stroke distance of the flow distributor clamp cylinder.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Compared with the prior art, the present technical solution replaces the manipulator consisting of a two-in-one gripper device of the side sealing plate and the flow distributor and a multi-axis industrial robot to replace manual labor in respectively clamping the side sealing plates from the baking and heating box and installing them on the transmission side and the operating side of the arc-shaped molten pool formed by the upper half of the two crystallization rollers of the thin-strip continuous casting unit; or clamping the flow distributor from the baking and heating box and installing it on the transmission side and the operating side of the water inlet plate of the thin-strip continuous casting unit, which can simultaneously meet the clamping action of the flow distributor and the side sealing plate without the need for replacement, avoiding the time cost and safety hazards caused by replacement, greatly improving efficiency and reducing labor intensity; the present technical solution has a simple structure and is easy to use.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that terms such as "bottom", "symmetrical", "inner", "vertical", "end", and "lateral" indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] The scenario of continuous casting and ironmaking includes a ladle, a tundish, a multi-stage flow distributor, a nozzle plate, a crystallization roller, a flow distributor, a side sealing plate, a multi-axis robot, a two-in-one gripper device for replacing the side sealing plate and the flow distributor, and a baking and heating box; this technical solution is a technical innovation for replacing the two-in-one gripper device for replacing the side sealing plate and the flow distributor based on this scenario.

[0031] See also Figure 1-10 As shown, the utility model is a two-in-one gripper device for replacing side sealing plates and flow distributors for thin strip continuous casting, comprising a bearing box 3;

[0032] The bottom of the carrying box 3 is hinged with cross-arranged side sealing plate clamps 5 for clamping the side sealing plate 4 and two sets of flow distributor clamps 2 for clamping the flow distributor 1; the two sets of flow distributor clamps 2 are symmetrically installed on both sides of the side sealing plate clamps 5;

[0033] A set of side sealing plate clamp cylinders 51 for lifting the side sealing plate clamp 5 and two sets of flow distributor clamp cylinders 21 for lifting the flow distributor clamp 2 are vertically installed in the bearing box 3; the end of the side sealing plate clamp cylinder 51 is connected to the cross position of the side sealing plate clamp 5 through a connecting shaft structure; the end of the flow distributor clamp cylinder 21 is connected to the cross position of the flow distributor clamp 2 through a connecting shaft structure;

[0034] The side sealing plate clamp cylinder 51, the flow distributor clamp cylinder 21 are connected to the bottom of the bearing box 3 through a hinge structure with a transverse limit hole. When the side sealing plate clamp cylinder 51 and the flow distributor clamp cylinder 21 are lifted or lowered, the side sealing plate clamp 5 and the flow distributor clamp 2 are driven to clamp or release.

[0035] Among them, the cross position of the side sealing plate clamp 5 and the cross position of the flow distributor clamp 2 are the axis centers of the movable rotating shaft.

[0036] Among them, the stroke distance of the side sealing plate clamp cylinder 51 is greater than the stroke distance of the flow distributor clamp cylinder 21; the side sealing plate clamp cylinder 51 is a multi-position compact cylinder with more than two strokes, and the number is 1; the flow distributor clamp cylinder 21 is a compact cylinder, the number is 2, and they are respectively installed on both sides of the side sealing plate clamp cylinder 51; the above three cylinders are all installed in a bearing box 3;

[0037] The side sealing plate clamp cylinder 51 is in a cross shape, and the middle intersection is the axis of the movable shaft. The extension and retraction of the side sealing plate clamp cylinder 51 drive the clamp to clamp and release the side sealing plate; due to the position limitation of the nozzle plate and the crystallization roller area, when the side sealing plate 4 is replaced, the side sealing plate 4 is installed behind the crystallization roller molten pool, and the side sealing plate clamp 5 is opened to the ready state position and cannot be returned in the fully opened state, so the side sealing plate clamp cylinder is set as a multi-position compact cylinder;

[0038] The flow distributor clamp 2 is in a cross shape, with the middle intersection being the axis of the movable shaft. The flow distributor clamp cylinder 21 is extended and retracted to drive the clamps on both sides to clamp and release the flow distributor 1 respectively.
