Problems solved by technology

When the diameter of the electrode increases to more than one meter, the existing steel wire rope tilting hoisting method will greatly affect the size of the material box of the roaster, greatly reduce the use efficiency of the roaster equipment, and significantly increase its energy consumption. At the same time, the safety and reliability of production operations are reduced
Therefore, the existing electrode lifting methods can no longer meet the needs of production and use, especially not suitable for the lifting and transportation of large-diameter electrodes.

Embodiment 2

[0021] Embodiment 2 of the present invention: when the large-diameter electrode 1 is hoisted by means of hoisting equipment, a central hole 1.1 is made at the center of the large-diameter electrode 1, and the central hole 1.1 is made without threaded blind hole or light hole, and then a lifting fastening device that can be connected to the central hole is installed in the central hole 1.1 through a tight fit connection. The lifting fastening device can use a lifting fastening device of the present invention Expansive lifting fastenings for lifting large diameter electrodes (e.g. image 3 shown), the expansion-type lifting and fastening device includes a hanging ring 2, a threaded mandrel 4 is fixed at the lower end of the hanging ring 2, and a threaded mandrel 4 is threaded on which a large-diameter electrode 1 can be placed. The expansion tube 5 in the central hole 1.1 of the blind hole type makes an open expansion cone 5.1 at the bottom of the expansion tube 5, so that when ...

Embodiment 3

[0022] Embodiment 3 of the present invention: when using lifting equipment to lift the large-diameter electrode 1 by hanging, first make a central hole 1.1 at the center of the large-diameter electrode 1, and make the central hole 1.1 as a design There is a hole with a ring groove 1.2, and then a lifting fastening device that can be connected to the central hole 1.1 is installed in the central hole 1.1 through a buckle connection. The lifting fastening device can use a Snap-in lifting fastening device for lifting large diameter electrodes (such as Figure 4 and Figure 5 shown), the buckle-type lifting fastening device includes a hanging ring 2, a T-shaped bar 7 is fixed at the lower end of the hanging ring 2, and the arc-shaped boss 7.1 at the lower end of the T-shaped bar 7 can be buckled on the large In the annular groove 1.2 in the central hole 1.1 of the diameter electrode 1, during manufacture, the diameter of the central hole 1.1 of the large-diameter electrode 1 is la...

Abstract

The invention discloses a lifting method and a lifting fastener for an electrode with major diameter. When the electrode with major diameter is lifted by lifting equipment through a suspending mode, a central aperture is prepared on the electrode with major diameter, then the lifting fastener capable of connecting to the central aperture is arranged on the central aperture, and the electrode with major diameter is suspended on a suspension ring of the fastener by hoisting equipment; so that the electrode with major diameter can be vertically lifted to a required position for dispose through a vertical lifting mode. When the electrode with major diameter is placed at the required position through vertical lifting, the lifting fastener is dismounted from the central aperture of the electrode with major diameter. The invention has advantages of simple structure and safe and convenient operation; besides, the invention has advantages of increasing security and reliability of a loading and unloading furnace of a roaster, effectively utilizing existing roaster hopper space to roast electrode, increasing energy utilization rate of an existing roaster and reducing energy consumption.

Description

technical field [0001] The invention relates to a lifting method and a lifting fastening device for a large-diameter electrode, and belongs to the technical field of electrode lifting used in metal smelting. Background technique [0002] During the firing process for electrode production, the electrodes are placed vertically in the furnace charge box. At present, the operation of loading and unloading the electrode is usually to use a steel wire rope to cover the electrode and lift it by lifting equipment. When using the existing wire rope hoisting method for hoisting, the electrode is in a tilted state, which requires the size of the material box of the roaster to meet the needs of hoisting. The increase in the size of the material box of the roasting furnace will not only reduce the use efficiency of the roasting furnace equipment, but also increase the energy consumption during roasting and increase the production cost of the roasting furnace equipment. Moreover, with t...
