Abstract

This application provides a hook-and-turn device for steel slag treatment, comprising two parallel ropes, with a lifting frame and a turning frame at each end of the ropes. The lifting frame consists of two parallel triangular frames, with a connecting rod fixed between corresponding corners of the two triangular frames. The turning frame consists of two U-shaped frames, with their openings connected and fixed to both ends of a connecting shaft. The ends of the two ropes form loops, which are respectively fitted onto the ends of the connecting rod and the connecting shaft. In this steel slag treatment hook-and-turn device, the lifting frame and turning frame can be placed on the ground via the frame structure, facilitating the connection of the ropes to the hook and the slag pot. The turning frame is hooked onto the lugs, and after the hook lifts the lifting frame, moving the hook upwards raises the lifting frame. The ropes and the turning frame pull the lugs, causing the slag pot to rotate around the lug and dump the steel slag. Moving the hook and slag pot downwards lowers the lifting frame and turning frame back to the ground and removes them.

Description

Technical Field

[0001] This application relates to slag pot tipping technology in steel slag treatment, and more particularly to a hook-and-hook tipping device for steel slag treatment. Background Technology

[0002] In the steel production process, steel slag treatment is an indispensable part. However, in traditional steel slag treatment operations, manually removing hooks and turning over cans is a high-risk, high-intensity, and labor-intensive task.

[0003] In the existing hot-quenching and slag-turning operation, the two ends of a loop rope are respectively attached to the hook and the lugs of the slag pot, connecting the hook and the slag pot. Then, the hook and the slag pot are moved synchronously to the slag dumping point. The hook pulls and rotates the slag pot via the rope to dump the steel slag. After dumping, the rope is detached from the slag pot and the hook.

[0004] Currently, the hooks are manually removed and placed, requiring operators to be directly below the high-temperature slag tank. This not only poses a threat to the health of the operators but also easily leads to safety accidents, posing a significant potential hazard to the lives of employees. Utility Model Content

[0005] This application provides a hook-and-turn device for steel slag treatment, which solves the problem that in existing steel slag treatment, manual hook-and-turn connection between the hook and the slag container is required.

[0006] This application provides a hook-and-turn device for steel slag treatment, including two parallel ropes. Each end of the ropes is equipped with a lifting frame and a turning frame. The lifting frame consists of two parallel triangular frames, with a connecting rod fixed between corresponding corners of the two triangular frames. The turning frame consists of two U-shaped frames, with the ends of the openings of the two U-shaped frames connected to each other and fixed to both ends of a connecting shaft. The ends of the two ropes form loops and are respectively fitted onto the ends of the connecting rod and the connecting shaft.

[0007] Optionally, the rope may be made of iron chain or steel wire rope.

[0008] Optionally, the connecting shaft is provided with a hanging frame that is fixed at an upward tilt of 45°.

[0009] Optionally, the ends of the two U-shaped frames at their openings are hinged to each other, allowing them to rotate and open about a connecting shaft.

[0010] Compared with the prior art, the beneficial effects of the hook-and-turn device for steel slag treatment provided in this application are:

[0011] The lifting frame and tilting frame can be placed on the ground via the frame structure, facilitating the connection of ropes to the hook and slag pot. The tilting frame is hooked onto the hanging lug via a connecting shaft hook, and the hook is used to lift the lifting frame via a connecting rod, tightening the ropes along the bottom wall of the slag pot.

[0012] Raising the hook lifts the hoisting frame, and by pulling the lugs via ropes and the tipping frame, the slag pot rotates around the trunnion to dump the slag. Lowering the hook and slag pot allows the hoisting frame and tipping frame to be returned to the ground and detached. Operators no longer need to be in the danger zone to remove or detach the ropes, effectively avoiding accidents such as high-temperature burns and slag splashes, greatly reducing the risk of injury.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0022] like Figures 1-5 As shown in the figure, one embodiment of this application provides a hook-and-turn device for steel slag treatment, including two parallel ropes 1, with a lifting frame 2 and a turning frame 3 respectively at both ends of the ropes 1. The lifting frame 2 is composed of two parallel triangular frames 4, with a connecting rod 5 fixed between corresponding corners of the two triangular frames 4. The turning frame 3 is composed of two U-shaped frames 6, with the ends of the openings of the two U-shaped frames 6 connected to each other and fixed to both ends of a connecting shaft 7, forming a triangular structure on both sides. The two ends of the two ropes 1 form loops, which are respectively sleeved on the ends of the connecting rod 5 and the connecting shaft 7.

[0023] In use, the rope 1 is positioned along the length of the hook 9 and the movement path of the slag pot 10. The lifting frame 2 and the tilting frame 3 are located at both ends of the rope 1. The slag pot 10 and the hook 9 are moved. The connecting rod 5 of the lifting frame 2 is positioned upwards, below the hook 9 at one end of the movement path of the slag pot 10. The connecting shaft 7 of the tilting frame 3 is positioned upwards, at the other end of the movement path of the slag pot 10. The hook 9 hooks the connecting rod 5 downwards, and the slag pot 10 extends forward, with the hanging lug 11 extending below the connecting shaft 7, so that the connecting shaft 7 is hooked on the hanging lug 11.

[0024] The tilting frame 3 is hung on the lug 11 on the other side of the slag pot 10. The hook 9 is moved upward to lift the tripod 4, so that the rope 1 is attached to and tightened along the bottom wall of the slag pot 10, while the slag pot 10 remains vertical. The rope 1, the lifting frame 2, and the tilting frame 3 move together with the slag pot 10 and the hook 9 to the slag dumping point. Then, the hook 9 is lifted upward, and the tilting frame 3 is pulled by the lifting frame 2 and the rope 1. The tilting frame 3 pulls the lug 11, causing the slag pot 10 to rotate and tilt around the trunnion at its upper end, dumping the steel slag from one side of the tilting frame 3.

[0025] After the steel slag is dumped, lower the hook 9 to move the lifting frame 2 down, restoring the slag pot 10 to a vertical position. The rope 1 is then tightened to fit snugly against the bottom of the slag pot 10. After the slag pot 10 is moved vertically out of the dumping area, move the hook 9 and slag pot 10 downwards, placing the lifting frame 2 and the tipping frame 3 on the ground. Move the hook 9 to detach from the connecting rod 5, and move the slag pot 10 to detach the hanging lug 11 from the connecting shaft 7. Then, remove the hook 9 and slag pot 10, and detach the rope 1, lifting frame 2, and tipping frame 3.

[0026] In this embodiment, the lifting frame 2 and the tilting frame 3 can be placed on the ground through the frame structure, which facilitates the connection of the rope 1 to the hook 9 and the slag jar 10. The tilting frame 3 is hooked onto the hanging lug 11 through the connecting shaft 7, and the hook 9 hooks the lifting frame 2 through the connecting rod 5, so that the rope 1 is tightened along the bottom wall of the slag jar 10.

[0027] Moving the hook 9 upwards lifts the lifting frame 2, and by pulling the lug 11 through the rope 1 and the tilting frame 3, the slag pot 10 can rotate around the trunnion to pour out the steel slag. Moving the hook 9 and the slag pot 10 downwards allows the lifting frame 2 and the tilting frame 3 to be lowered back to the ground and removed.

[0028] In one possible implementation, the rope 1 is made of iron chain or steel wire rope.

[0029] The iron chain is easier to bend and fit snugly against the bottom of the slag pot 10, providing better stability during the tipping process and making it easier to place on the ground when detaching or hanging. The steel wire rope, on the other hand, has higher tensile strength, greater wear resistance, and a longer service life.

[0030] In one possible implementation, the connecting shaft 7 is provided with a hanging frame 8 that is fixed at an upward tilt of 45°.

[0031] The hanging frame 8 is fixed at an angle to the connecting shaft 7. The hanging frame 8, which is inclined towards the hanging ear 11, is farther away from the U-shaped frame 6. When moving the slag pot 10, it is less affected by the U-shaped frame 6, making it easier to hang on the hanging ear 11 and easier to detach when picking it up or putting it down.

[0032] In one possible implementation, the ends of the openings of the two U-shaped frames 6 are hinged to each other and can rotate and open about the connecting shaft 7.

[0033] The hinged U-shaped frame 6 can be rotated and opened, making it easy to place vertically on the ground. At the same time, the height of the connecting shaft 7 can be adjusted by opening and closing.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
