Abstract
The utility model relates to a large section water cooling cable with rotation function, a hose and a joint which can rotate when a furnace cover and a conductive cross arm rotate; the hose does not bear torsional moment, which eliminates the twist of hose in the conventional large section water cooling cable when the furnace cover and the conductive cross arm rotate. The utility model comprises a cable main body, two ends of which are provided with the joints; the joint at one end of the cable is a rotation joint, which comprises a joint body; the outer end of joint body is a connection end, which is connected with the conductive cross arm and a conductive copper tube; the core part in the inner end of the joint body is connected with a copper stranded conductor cable. The joint body is covered with a loop which is covered with a hose; the hose is pressed on the loop through a nonconducting alnico; an O-shape seal ring is provided between the loop and the joint body to form a rotation seal.
Description
One, technical field:
The utility model relates to a kind of water-cooled cable, especially relates to a kind of water-cooled cable with big section with spinfunction.
Two, background technology:
Water-cooled cable with big section is the vitals of arc furnace and ladle refining furnace.Its function is to pass through the powerful conduction of current of contact tube after the furnace transformer step-down to conductive cross arm.This electric current is up to tens thousand of peaces.The structural feature of water-cooled cable with big section is---core is a copper stranded conductor, and the two ends of copper stranded conductor are furnished with joint, and the outside of copper stranded conductor is with sebific duct.Logical cooling water in the cable when work.The pressure of cooling water is 0.8Mpa.Arc furnace bell when reinforced is outwarded winding, reinforced back cycle, and the anglec of rotation is 60---85 degree, this moment, conductive cross arm and electrode mast rotated together with bell.Electric cable with large cross-section is also corresponding in this process has reversed 60---85 degree.The ladle refining furnace of double water-cooled cable when the station conversion also will be done similar rotation.The shortcoming of tradition water-cooled cable with big section structure is, the joint of water-cooled cable and sebific duct are withheld together, and the cable sebific duct is turned round when bell and conductive cross arm rotate, and easily causes and leaks, and the life-span is low.And sebific duct is subjected to twisting strain, and the water flowing area of section of sebific duct reduces, and reduced the flow of cooling water, influences the cooling of cable.Particularly current electric furnace is to large scale development, and cable size is big, and cooling water pressure increases, and above-mentioned shortcoming is more obvious.
Three, utility model content:
The utility model is in order to solve the weak point in the above-mentioned background technology, a kind of water-cooled cable with big section with spinfunction is provided, its sebific duct and joint when the rotation of bell and conductive cross arm can rotate, make sebific duct not bear moment of torsion, thoroughly eliminated the distortion of traditional water-cooled cable with big section sebific duct when bell and conductive cross arm rotation.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of water-cooled cable with big section with spinfunction comprises cable body, and the cable body two ends are furnished with joint, and its special character is: the joint of cable one end is a swivel joint.
Above-mentioned swivel joint comprises fittings body, and the outer end of fittings body is a link, links to each other with conductive cross arm or contact tube, and the core and the stranded copper cable of the inner of fittings body are fastening, are with kink on the fittings body, and kink is with sebific duct outward.
Above-mentioned sebific duct is pressed on the kink with magnetic conduction steel band not.
Be provided with " O " shape sealing ring between above-mentioned kink and fittings body, form rotary seal.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, the utility model is a kind of novel water-cooled cable with big section with spinfunction, at the end (two ends) of cable swivel joint is set, and sebific duct and joint can rotate when bell and conductive cross arm rotation, make sebific duct not bear moment of torsion.Thoroughly eliminated the distortion of traditional water-cooled cable with big section sebific duct when bell and conductive cross arm rotation.
2, the water-cooled cable with big section of swivel joint being arranged is a kind of cable that is different from the new shape of traditional water-cooled cable with big section, all improves a lot at aspects such as useful life, cooling capacity, applicable elements.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of swivel joint in the utility model.
Fig. 3 is a course of work schematic diagram of the present utility model.
Among the figure, 1-fittings body, 2-cutting ferrule, 3-kink, 4-round section joint ring sealing ring, 5-packing ring, 6-swivel joint.
Five, embodiment:
Referring to Fig. 1, the utility model is a kind of arc furnace or ladle refining furnace of being used for, with the device of the powerful conduction of current by contact tube after the furnace transformer step-down to the conductive cross arm, to form by cable, joint and sebific duct, an end connector wherein is a swivel joint 6.The composition of water-cooled cable with big section swivel joint 6 is made up of fittings body 1, cutting ferrule 2, kink 3, " O " shape sealing ring 4, packing ring 5 as shown in Figure 2.The outer end of fittings body 1 is a link, links to each other with conductive cross arm or contact tube, and the core and the stranded copper cable of the inner of fittings body 1 are fastening, are with kink 3 on the fittings body 1, and glue pipe socket is pressed on sebific duct on the kink 3 with magnetic conduction steel band not outside kink 3.1 of kink 3 and fittings body have round section joint ring sealing 4, form rotary seal.Because all parts are all worked in high-intensity magnetic field, part is all made with non-magnet_conductible material.
Referring to Fig. 3, during real work, after water-cooled cable is installed, cable leads to cooling water, (for example rotates 70 degree) when bell is outwarded winding, and the center that is connected in the rotatable cable joint 6 of conductive cross arm end moves to reposition in company with the conductive arm end, meanwhile cable reverses an angle (is 70 degree by precedent) around this center, the stranded copper cable of cable core is spiral, can bear and reverse, and the sebific duct twisting property is poor.But it is pressed on the kink, and kink 3 can rotate with 1 of fittings body, is sealed by sealing ring 4 between the surfaces of revolution.Like this, in the cable course of work, eliminated reversing of sebific duct.
