Abstract
The utility model relates to a conducting and water cooling type electrode cross arm, which omits a conducting copper pipe and a supporting mechanism thereof. The utility model is composed of a cross arm body, a draw rod in the cross arm body, a damping brake take-up unit, a front end conducting plate, a damping brake, etc. The draw rod is arranged in an inner core pipe which is connected with the cross arm body via an upper ribbed slab, a lower ribbed slab, a left water stop sheet and a right water stop sheet. The lower part of the space of the inner core pipe is an intake tunnel, and the upper part is an outtake tunnel. In order to achieve security and reducing the loss of the branch current, insulating parts are arranged between related members. The cross arm is suitable for being matched with an electrical arc furnace. The utility model has the advantages of compact structure, high rigidity, convenient maintenance, small resistance, and reactance, large power of input electric arc furnace, remarkable effect of power saving, etc. The utility model is not easy to damage.
Description
The utility model relates to a kind of and the supporting application of electrical arc furnace, be from the flexible cable to the electrode between, rise and seize on both sides by the arms with the cantilever support electrode and drive its lifting, and the electric-pole horizontal arm of transmission of electric energy effect.
The electric-pole horizontal arm of continuing to use is for many years seized device on both sides by the arms with electrode, only seize on both sides by the arms, cantilever support electrode and drive the effect of its lifting, and the task of transmission of electric energy is born by the water-cooled contact tube that is installed in the electric-pole horizontal arm top, the latter also need have special bracing frame to support, they are loosely organized, all be in the high-temperature region, need with stream in the cooling water, the load that bears is big, quickens lifting during work, cause vibration even resonance, copper pipe easily leaks and fractures, and does not have gusset and inner core tube in the electric-pole horizontal arm, the rigidity deficiency, intensity is not good enough, easy fault during operation and damaging.This contact tube is big because of length, and sectional area is little, and resistance and reactance are big, and the power in the input arc furnace is low, and the duration of heat is long, and energy consumption is big.
What the utility model was designed a kind of compact conformation at the deficiencies in the prior art part does not need water-cooled contact tube and bracing frame thereof, that rigidity foot, mechanical strength are big, resistance and reactance little, power height in the input arc furnace, the duration of heat is short, the significant conductivity water cold type of energy-saving efficiency electric-pole horizontal arm.
The purpose of this utility model can realize by following measure: it is by the transverse arm body, pull bar in it, the electrode band-type brake of pull bar front end, the band-type brake tension spring and the terminal band-type brake at rear portion unclamp compositions such as cylinder, transverse arm body front end has the conductive plate fastening with the electrode band-type brake, the electrode band-type brake stretches between the part of transverse arm body inside and the pull bar insulating sleeve and packing ring, between transverse arm body and the column insulation board is arranged, between transverse arm body and the pull bar inner core tube is arranged, they are connected with water-stop sheet by the gusset of welding up and down, its space is the intake tunnel of below and the exhalant canal of top, and water inlet and delivery port are at transverse arm body end.
The also available following measure of the utility model comes perfect: band-type brake unclamps the cylinder that cylinder is a pair of series, and its connecting rod links to each other with pull bar by lever; Band-type brake tension spring can be selected butterfly spring for use; The transverse arm body is the forming laminated sheet material welding thing of steel in the outer copper; In the electrode band-type brake cooling-water duct is arranged.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model is described in detail below in conjunction with embodiment:
Band-type brake tension spring 2 is selected butterfly spring or coil spring for use, band-type brake unclamps cylinder 4 and selects cylinder or fluid cylinder for use, main consideration elastic force is applied to the size of the power of seizing on both sides by the arms in the band-type brake 13 and a stroke long and short two factor of pull bar 8, generally can so arrange: the two cylinders of usefulness series connection, the effect of lever 1 is arranged, power and stroke all have increase, two cylinders can be placed outside the transverse arm body 7, select for use helical spring to get final product; With fluid cylinder, then place in the transverse arm body 7, select for use butterfly spring better.The electrode band-type brake 13 of pull bar 8 front ends is through conductive plate 12 mediation electric currents, power consumption for the shunt current that reduces electrode band-type brake 13 forms has insulating sleeve 10 and packing ring 11 at pull bar 8 contact sites such as grade, for safety, insulation board 3 is arranged between transverse arm body 7 and the column, and their epoxy available insulating material are made.The workpiece that links to each other with insulating part all will have cooling-water duct, inner core tube 6 can be a garden shape pipe, it also can be rectangular tube, for separating water channel, inner core tube 6 both sides are linked to each other with transverse arm body 7 by water-stop sheet 14, and the below is an intake tunnel 9, and the top is an exhalant canal 5, for gaining in strength, inner core tube is connected by gusset 15 transverse arm bodies 7 about in the of 6.Water inlet and delivery port are in transverse arm body rear end.Be in the electrode band-type brake 13 of high-temperature region, cooling-water duct to be arranged for well.
The utility model is changed the conventional practice of carrying electric current with water-cooling contact tube, Electric-pole horizontal arm conduction because adopting copper-steel composite plate to make has reduced contact tube and has reached Inner core tube in the structures such as its supporter, transverse arm body and water-stop sheet, gusset are carried greatly The high rigidity of electric-pole horizontal arm has improved the antivibration effect, antileaking and fracture fortune Fault is difficult for long service life takes place during row. Because the length of transverse arm body is little, cut Area is big, and the complex copper steel plate structure of steel subtracts reactance and resistance greatly in the outer copper Little, the power of input electric arc furnaces is big, and the duration of heat is short, and power savings is remarkable.
