Abstract
The utility model relates to hydraulic oil equipment for realizing charged electrode slipping of a metallurgical submerged arc furnace, in particular to a hydraulic internal contracting brake for the metallurgical submerged arc furnace. The brake is characterized by comprising an annular cavity of which the upper part and the lower part are connected through a hydraulic oil cylinder, wherein a temperature-resistant and wear-resistant arc brake shoe is arranged on the inner wall of the annular cavity in a matched mode; and hydraulic jacking devices are uniformly fixedly arranged on the brake shoe. The brake has a unique structure and high safety and can realize charged electrode slipping.
Description
Technical field
The utility model relates to the hot stove in a kind of metallurgical ore deposit and realizes the charged hydraulic oil equipment that presses, and especially relates to the hydraulic contracting that the hot stove in a kind of metallurgical ore deposit is used.
Background technique
The hot stove in present metallurgical ore deposit all is to have a power failure to press electrode, because the smelting row also highly has strict requirement to transferring of electrode, ability lower electrode after this power failure presses and needs to have a power failure, thus not only increase reactive load, can not be fully used the working lipe of smelting, and electric energy loss is bigger.Also there be not at present a kind of the realization to press electrode, device that Security is big with point.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of structure uniqueness is provided, can realizes pressing the hydraulic contracting that electrode, the hot stove in metallurgical ore deposit that Security is big are used with point.
The utility model is realized in the following way:
A kind of hydraulic contracting is characterized in that: it comprises the toroidal cavity that is formed by connecting by hydraulic jack up and down, along being combined with heatproof, wear-resisting arc brake shoe on the inwall of toroidal cavity, evenly is fixed with the hydraulic pressure tight-push unit on brake shoe;
Described hydraulic pressure tight-push unit is eight groups, and its right wing connects, and circulation is closed in due order;
Described toroidal cavity is circular;
Be coated with the fluorine colloid of heat-resistant, wear-resistant on the outer wall of described brake shoe;
Diameter after described all brake shoe closures is identical with the diameter of the electrode that is mated.
The utility model has following effect:
1) structure uniqueness: the utility model provide it comprise the toroidal cavity that is formed by connecting by hydraulic jack up and down, along being combined with heatproof, wear-resisting arc brake shoe on the inwall of toroidal cavity, on brake shoe, evenly be fixed with the hydraulic pressure tight-push unit, make its tight-push unit carry out fore and aft motion by hydraulic system pressure, the arc brake shoe that at this moment tight-push unit connected by with the operation that presses of holding and combine fully the realization electrode fully tightly of electrode.
2) simple to operate, transfer the more accurate control of electrode height, Safety performance improves greatly: band-type brake is closed fully up and down in order to make by disc spring force down for the common state of the device that the utility model provides, combine with electrode and to hold tightly, in the time of need pressing electrode, last band-type brake tight-push unit is by the oil pressure bottom of withdrawing fully, and pressing oil cylinder simultaneously, to rise on the height that need press electrode band-type brake closed fully.With under band-type brake open fully, press oil cylinder piston bar withdrawal bottom, this at present the complete closure of band-type brake hold tightly.At this moment band-type brake is got back to common state, presses electrode until next time.
3) device that provides of the utility model is realized discharging electrode with voltage, reduce electric energy loss, thereby economic benefit is significantly improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model band-type brake package assembly schematic representation up and down.
Embodiment
A kind of hydraulic contracting, as shown in Figure 1: it comprises the toroidal cavity 2 that is formed by connecting by hydraulic jack 7 up and down, along being combined with heatproof, wear-resisting arc brake shoe 1 on the inwall of toroidal cavity 2, evenly is fixed with hydraulic pressure tight-push unit 3 on brake shoe 1.
Above-mentioned hydraulic pressure tight-push unit 3 is eight groups, and its right wing connects, and circulation is closed in due order.
Above-mentioned toroidal cavity 2 is circular.
Be coated with the fluorine colloid of heat-resistant, wear-resistant on the outer wall of above-mentioned brake shoe 1, its thickness is more than 8 millimeters.
Diameter after above-mentioned all brake shoe 1 closures is identical with the diameter of the electrode that is mated.
Band-type brake is closed fully up and down in order to make by disc spring force down for the common as shown in Figure 2 state of the device that the utility model provides, combine with electrode and to hold tightly, in the time of need pressing electrode, last band-type brake tight-push unit is by the oil pressure bottom of withdrawing fully, and pressing hydraulic jack 7 simultaneously, to rise on the height that need press electrode band-type brake closed fully.With under band-type brake open fully, press oil cylinder 7 piston rods withdrawal bottom, this at present the complete closure of band-type brake hold tightly.At this moment band-type brake is got back to common state, presses electrode until next time.
