Owing to the adoption of the scheme, the lifting device for the electrode of the submerged arc furnace ensures the verticality and improves the stability in the lifting process.
Description
Technical field
The utility model relates to a kind of lowering or hoisting gear, relates in particular to a kind of lowering or hoisting gear that is used for electrodes in mine hot stove.
Background technology
At present, in metallurgical industry, hang cylinder formula electrode lifting device and be widely used, this device has compact conformation, stable drive, be convenient to realize plurality of advantages such as automation mechanized operation, therefore be widely used in big-and-middle-sized electric furnace, be illustrated in figure 3 as and hang cylinder formula electrode lifting device schematic diagram, it is made up of last carrying cylinder 1, guider 2 and hydraulic lifting oil cylinder 3, hydraulic lifting oil cylinder 3 is the piston-type hydro compressing cylinder, its with platform and last carrying cylinder 1 between all connect with bearing pin, be the hinge type and connect.But in the process of using, when the hot furnace body in ore deposit rotated, furnace charge will change to the horizontal applied force of electrode, thereby electrode is offset.Because hanging the hydraulic jack hinge type of cylinder formula electrode lifting device is connected in platform and goes up carrying cylinder, so electrode will suitably be adjusted perpendicularity according to the situation of power on every side in the process that moves up and down, to guarantee that electrode can not fracture, but such connecting mode also has certain drawback, on the one hand the perpendicularity of electrode does not just guarantee, the stability during rise fall of electrodes is also bad on the other hand.
Therefore, how can create a kind of lowering or hoisting gear, make that the lifting process held stationary of electrodes in mine hot stove is this area problem demanding prompt solution.
Summary of the invention
The utility model provides a kind of lowering or hoisting gear that is used for electrodes in mine hot stove of metallurgy industry, solved the problem that electrodes in mine hot stove can not guarantee perpendicularity and fluctuation of service up and down in the running.
In order to address the above problem, the utility model has adopted following technical scheme: a kind of lowering or hoisting gear that is used for electrodes in mine hot stove, electrode lifting device is installed on the rise fall of electrodes platform, includes electrode guide, goes up carrying cylinder, hoist cylinder, needle beam and suspension rod.It is characterized in that, electrode guide is rigidly fixed on the rise fall of electrodes platform by bolt, hydraulic lifting oil cylinder bottom is rigidly fixed on the electrode guide by bolt, and hydraulic lifting oil cylinder top is connected with electrode holder tube crossbeam by needle beam and suspension rod.Adopt bolt and sphere bonded washer to connect connecting between hydraulic lifting oil cylinder top and needle beam, needle beam and suspension rod.
This lowering or hoisting gear that is used for electrodes in mine hot stove also includes electrode, and last carrying cylinder obvolvent electrode does pumping under the drive of hydraulic lifting oil cylinder.
During work, at first, the hydraulic lifting oil cylinder is oil-filled, drives crossbeam and last carrying cylinder and rises, and realizes the process that electrode is raised, and the hydraulic jack emptying drives crossbeam and last carrying cylinder and descends then, realizes the process that electrode descends.When the hot furnace body in ore deposit rotates, furnace charge will change to the horizontal applied force of electrode, thereby electrode is offset, will by sphere bonded washer adjust perpendicularity between hoist cylinder top and needle beam and needle beam and the suspension rod this moment, and hoist cylinder bottom and electrode guide also usefulness be Bolt Connection, so just solved the problem of electrode fluctuation of service in the process of moving up and down to a certain extent.
In sum, adopted the technical solution of the utility model after, can effectively raise the stability of electrode in running.

Embodiment
In order better to understand feature of the present utility model, purpose and function, here earlier to the hot stove in ore deposit and electrode lifting device with and in conjunction with making an explanation:
The hot stove in ore deposit claims electric arc electric furnace or resistance electric furnace again.It is mainly used in raw materials such as reducing and smelting ore, carbonaceous reducing agent and solvent.Its work characteristics be adopt carbonaceous or magnesia refractories make furnace lining, use from train electrode, electrode inserts furnace charge and carries out arc-covering slag operation, utilize the energy and the electric current of electric arc to come smelting metal by the furnace charge produce power, reinforced successively, batch (-type) goes out scum, a kind of industrial furnace of working continuously.
Electrode lifting device is the visual plant of mine heat furnace smelting, and when the smelting situation was unstable, electrode need promote and descend, guarantee electrode perpendicularity, prevent that electrode fracture when smelting from being one of difficult point technology of electrode lifting device.
Below in conjunction with accompanying drawing and Reference numeral a specific embodiment seat cylinder formula electrode lifting device of the present utility model is described in detail, is described as follows:
Fig. 1 and Fig. 2 are respectively the crossbeam detail drawing in a cylinder formula electrode lifting device structural representation and the seat cylinder formula electrode lifting device.
As shown in Figure 1, the described seat of this embodiment cylinder formula electrode lifting device, it is installed on the rise fall of electrodes platform, include electrode guide 7, go up carrying cylinder 1, hydraulic lifting oil cylinder 3, needle beam 2 and suspension rod 9, wherein, electrode guide 7 is rigidly fixed on the rise fall of electrodes platform by bolt, and hydraulic lifting oil cylinder 3 bottoms are rigidly fixed on the electrode guide 7 by bolt, and hydraulic lifting oil cylinder 3 tops are connected with electrode holder tube 1, crossbeam 2 by needle beam 2 and suspension rod 9.Adopt bolt and sphere bonded washer 8 to connect connecting between hydraulic lifting oil cylinder 3 tops and the needle beam 2, needle beam 2 and suspension rod 9.
Wherein the hydraulic lifting oil cylinder in the present embodiment is the plunger hydraulic hoist cylinder.
Adopted the described lowering or hoisting gear that is used for electrodes in mine hot stove of present embodiment, during work, at first, the hydraulic lifting oil cylinder is oil-filled, drive crossbeam 2 and 1 rising of last carrying cylinder, realize the process that electrode is raised, then the hydraulic jack emptying, drive crossbeam 2 and 1 decline of last carrying cylinder, realize the process that electrode descends.When the hot furnace body in ore deposit rotates, furnace charge will change to the horizontal applied force of electrode, thereby electrode is offset, will by sphere bonded washer 8 adjust perpendicularity between hoist cylinder 3 tops and needle beam 2 and needle beam 2 and the suspension rod 9 this moment, and hoist cylinder bottom and electrode guide also usefulness be Bolt Connection, so just solved the problem of electrode fluctuation of service in the process of moving up and down to a certain extent.
The above only is a specific embodiment of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection range of the present utility model.
