Description

Technical Field

[0001] This utility model belongs to the field of metallurgical technology, specifically relating to a hoisting device for constructing an electric arc furnace. Background Technology

[0002] The lining of the electric arc furnace is constructed from various materials. During the lining construction, the materials need to be hoisted into the furnace. The height difference between the furnace and the platform is 5 meters. Because the furnace has a cover, overhead cranes cannot be used to hoist the materials. In existing technology, the materials are often hoisted through the furnace door. Specifically, a forklift is used to transfer the materials to the door, and temporary hoisting equipment is erected inside the furnace to transport the materials further inside. This process requires the materials to be transferred using different equipment, significantly reducing work efficiency and increasing the labor intensity for workers. Utility Model Content

[0003] This utility model provides a hoisting device for the construction of a submerged arc furnace to address the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hoisting device for constructing an electric arc furnace includes a forklift body. A mounting plate is fixedly installed on the fork carriage at the front end of the forklift body. A fixing plate is fixedly connected to the mounting plate by bolts. A lifting beam is welded to the fixing plate. A support plate is fixedly welded to the lifting beam near the forklift body. A winch is installed on the support plate. A groove is formed at the front end of the lifting beam. A fixed pulley is rotatably installed in the groove. A wire rope on the winch passes over the fixed pulley and is fixedly connected to a hook. The winch is connected to a controller and a DC power supply via a wired connection.

[0006] Furthermore, a baffle is provided at the front end of the groove to prevent the wire rope from running out of the fixed pulley.

[0007] Furthermore, a diagonal brace is welded between the fixed plate and the hanging beam.

[0008] Furthermore, a bracket is welded onto the support plate for suspending the controller.

[0009] Furthermore, a counterweight is fixedly connected to the front end of the wire rope to apply pressure to the wire rope under no-load conditions, ensuring that the wire rope is in a taut state and thus preventing it from running out of the fixed pulley.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This invention mounts a lifting beam on the forklift body, enabling both horizontal movement and hoisting of masonry materials. When hoisting masonry materials into the electric arc furnace, there is no need to transfer them through different equipment; the masonry materials can be transferred from the platform to the bottom of the electric arc furnace in one go, greatly improving work efficiency and reducing the labor intensity of workers.

[0015] To further illustrate the technical solution of this utility model, the following embodiments will be used to further explain this utility model.

[0016] like Figure 1 and Figure 2 As shown, a hoisting device for constructing a submerged arc furnace includes a forklift body 1. A mounting plate 2 is fixedly mounted on the fork carriage at the front end of the forklift body 1. A fixing plate 3 is bolted to the mounting plate 2. A lifting beam 4 is welded to the fixing plate 3. A diagonal brace 12 is welded between the fixing plate 3 and the lifting beam 4. A support plate 5 is fixedly welded to the lifting beam 4 near the forklift body 1. A winch 6 is mounted on the support plate 5. A groove 7 is formed at the front end of the lifting beam 4, and a fixed [device / mechanism] is rotatably mounted within the groove 7. The pulley 8 has a baffle 11 at the front end of the groove 7 to prevent the wire rope from running out of the fixed pulley 8. The wire rope on the winch 6 is fixedly connected to the hook 9 after passing over the fixed pulley 8. The front end of the wire rope is also fixedly connected to the counterweight 14 to apply pressure to the wire rope in the no-load state, so as to ensure that the wire rope is in a taut state and thus prevent it from running out of the fixed pulley 8. The winch 6 is connected to the controller 10 and the DC power supply by wired connection. A bracket 13 is welded on the support plate 5 for suspending the controller 10.
