Description

Technical Field

[0001] This utility model relates to the field of workshop box-closing tooling equipment, and in particular to a clamping tool for the box-closing process of remelted billets. Background Technology

[0002] In metallurgical production, the ingot-pulling electroslag furnace in the electroslag furnace workshop is an important device for remelting. During its operation, the hoisting and box-closing of the remelting billets directly affect the processing efficiency and operational safety. These billets are mostly irregular, multi-segmented cylindrical shapes and need to be hoisted multiple times while in an upright position. When closing the box, the neck of the billet must be precisely clamped to ensure positional stability.

[0003] Currently, the lack of suitable tooling in this cross-operation area presents numerous difficulties in the assembly process of remelted billets. Without specialized tools, operators must manually adjust the billet's posture and perform clamping and transfer, significantly increasing labor intensity. Furthermore, the billets' weight and irregular shape make them prone to swaying or falling during hoisting, reducing safety. Frequent manual intervention also prolongs assembly time, impacting overall operational efficiency and contradicting the principles of green, safe, and environmentally friendly production development.

[0004] Therefore, considering the morphological characteristics of the remelting billet and the requirements for hoisting and packing, there is an urgent need to design a tool that can accurately clamp the neck and is suitable for hoisting in an upright position. This is the key to improving the existing operational difficulties. It can effectively reduce the intensity of manual labor, improve the safety factor and efficiency of operation, and better meet the green and safe production requirements of the workshop. Utility Model Content

[0005] The technical problem this invention aims to solve is to provide a clamping tool for the process of packing remelted billets. It addresses the issue of the difficulty in transferring remelted billets, which affects packing efficiency, by enabling convenient and quick transfer of the billets, reducing manual labor intensity, and improving operational safety and efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a clamping tool for the process of packing remelted billets, including a hollow cylindrical shell, a number of lifting lugs are provided on the outside of the hollow cylindrical shell, two through holes are provided through the middle of the side wall of the hollow cylindrical shell, a claw is provided inside the through hole and a detachable plug is provided on the outside, and a spring is provided between the claw and the detachable plug.

[0007] A further improvement of the present invention is that the claw structure includes a claw base that is identical in shape to the through hole and has an outer diameter smaller than the inner diameter of the through hole, allowing it to move freely within the through hole. A clamping part is fixedly provided on the claw base via a connecting beam. The clamping part is a notched rectangle, meaning that the notched corner of the extended rectangular part slopes upward from the outside to the inside.

[0008] A further improvement of this utility model is that the inclined surface of the clamping part is a smooth surface, and anti-slip texture is provided on the top surface of the clamping part.

[0009] A further improvement of this utility model is that the through hole is a round hole, part of which is a smooth hole and part of which has an internal thread on its inner wall, and the detachable plug is a bolt that is compatible with the internal thread.

[0010] A further improvement of this utility model is that: several rotating handles extend from the bolt head of the detachable plug for easy tightening.

[0011] A further improvement of this utility model is that the detachable plug is a gasket, which is fixed to the side wall of the hollow cylindrical shell by bolts or clips to cover the through hole.

[0012] The technological advancements achieved by this invention, due to the adoption of the above-mentioned technical solution, are as follows: By setting a cylindrical outer shell in conjunction with internal clamping claws, the remelted billet can be clamped when it enters the cylindrical outer shell from bottom to top, making transportation convenient and safe using lifting lugs, and allowing for more precise control over the position. Furthermore, by setting a detachable plug, when clamping and transportation are complete, the plug can be removed, causing the clamping claws to naturally loosen, facilitating the next clamping operation.

[0018] The components include: 1. Hollow cylindrical shell; 2. Lifting lug; 3. Through hole; 4. Claw; 5. Removable plug; and 6. Spring. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to embodiments:

[0020] Example 1:

[0021] like Figure 4 The diagram shows a structural schematic of the remelting billet, which is an irregular multi-segment cylindrical structure. Because it requires multiple vertical lifting operations to complete the assembly, this application was invented to facilitate the lifting of this remelting billet. Figure 1 Figure 2 shows a schematic diagram of a clamping tool for the remelting billet assembly process according to this application. It includes a hollow cylindrical shell 1, shaped like a tube with a certain wall thickness. Several lifting lugs 2 are provided on the outside of the hollow cylindrical shell 1, allowing for easy and secure hooking and fixing with steel wire ropes, facilitating transport by an overhead crane, and moving the remelting billet into the crystallizer. The interior of the hollow cylindrical shell 1 is also a hollow cylinder. Two through holes 3 are provided on the side wall of the hollow cylindrical shell 1 at the center of the cylinder axis. The two through holes 3 are of the same size and positioned opposite each other. A protruding claw 4 is provided inside each through hole 3, extending into the internal space of the hollow cylindrical shell 1. A removable plug 5 is provided on the outside of each through hole 3. A spring 6 is provided between the claw 4 and the removable plug 5. When the removable plug 5 is fixedly installed on the outside of the through hole, it is securely installed, effectively supporting the spring and providing a rebound force for the claw.

[0022] like Figure 3The diagram shows the structure of the chuck, including a chuck base. A clamping part is fixedly mounted on the chuck base via a connecting beam. Two opposing chucks are arranged inside two opposing through holes 3. The two chucks work together to clamp the neck of the remelting billet. Specifically, the chuck base and the through hole 3 have the same shape. In this embodiment, the through hole 3 is a circular through hole, and the chuck base is a cylindrical base with an outer diameter smaller than the inner diameter of the through hole 3, allowing it to move freely within the through hole 3. The clamping part is a notched rectangle with the notched corner extending outwards. The notched part of the extended clamping part slopes upwards from the outside to the inside. The inclined surface of the clamping part is a smooth surface, and anti-slip texture is provided on the top surface of the clamping part. In this embodiment, the through hole 3 is a circular hole. Part of the inner wall of the through hole is smooth and is a smooth hole for the free movement of the chuck 4. The other part is a threaded hole with internal threads on the inner wall. The removable plug 5 is a bolt, and the size and external thread of the bolt match the threaded part of the through hole. To facilitate tightening, loosening, and disassembly, several outward-extending rotating handles can be welded to the nut on the bolt head. Holding the handles increases the torque for rotation. When using this tool to clamp remelting billets, a crane is used to hoist the tool, which is then placed over the billet from top to bottom. The billet enters the cylinder from bottom to top. As the head of the billet rises, it can push open the jaws, which retract into the through-hole, compressing the spring. When the head passes through and the neck contacts the jaws, the spring returns to its original position, ejecting the two jaws to lock the neck, thus clamping the billet. The crane then moves the clamped billet to a suitable position. After closing the box, the plug is unscrewed, the spring releases its force, the jaws release, and the clamping and repositioning are complete.

[0023] Example 2: This example is based on Example 1, with only the detachable plug 5 being modified. In this example, the detachable plug 5 is a gasket, which is fixed to the side wall of the hollow cylindrical shell 1 by bolts or clips, in a position that covers the through hole 3. This structure makes the fixation more secure, but disassembly is more complicated.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
