Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] like figure 1 As shown, an electrode lifting device includes a hydraulic cylinder 1, a chain 2, a lifting arm 3, a fixed slide rail 4 and an electrode holder 7. A gear 6 is connected to the end of the piston rod of the hydraulic cylinder 1, and the chain 2 The chain link of the chain fits with the teeth of the gear 6. One end of the chain 2 is fixed, and the other end is connected to the lifting arm 3. Pulleys 34 are installed on both sides of the lifting arm 3 and fixed slide rails 4 are arranged accordingly. The pulleys 34 and The rails of the fixed slide rail 4 are in contact, and the electrode holder 7 is installed at the end of the lifting arm (3) away from the end of the chain 2 .
[0021] The above scheme is the main implementation scheme. The hydraulic cylinder 1 is used as the jacking power, and the cylinder can also be used for jacking. The end of the...

The invention relates to the field of arc furnaces, in particular to an electrode hoisting device. As an electrode hoisting part is arranged, electrode clamped parts can fall near the ground to eliminate a certain potential safety hazards of aerial operations. The electrode hoisting device comprises a hydraulic oil cylinder, a chain, a hoisting arm, a fixed slide rail and an electrode clamping machine; the end part of a piston rod of the hydraulic oil cylinder is connected with a gear; chain links of the chain are sleeved with teeth of the gear; one end of the chain is fixed, and the other end is connected with the hoisting arm; pulleys are mounted on two sides of the hoisting arm, and are correspondingly provided with fixed slide rails; the pulleys are contacted with rails of the fixed slide rails; and the electrode clamping machine is mounted at the end of one end, far from the chain, of the hoisting arm. The electrode hoisting device uses the movable pulley similar principle for realizing lifting of the electrode clamped parts and falling near the ground to conveniently guarantee the safety of maintenance work of the parts.
Description
technical field [0001] The invention relates to the field of electric arc furnaces, in particular to an electrode lifting device. Background technique [0002] Electric arc furnace steelmaking is a steelmaking method in which electric energy is used as a heat source. It relies on the electric arc generated by the discharge between the electrode and the charge, so that the electric energy is converted into heat energy in the arc light, and the metal charge and the charge are heated and melted by the direct action of the arc radiation and the arc. Slag is a steelmaking method that smelts steel and alloys with various components. [0003] Electric arc furnace steelmaking needs to insert electrodes into the furnace body, so the device is generally equipped with an electrode clamping part and an electrode lifting part, etc. At present, the electrode clamping part of some electric arc furnaces is a beam suspended in midair. The electrodes are inserted in the same way, and some of...
