Abstract
The invention relates to a cable connection device of a conductive cross arm of a hook overlap-joint type ladle refining furnace. The cable connection device comprises three connection boards on the lateral faces and the upper part, a front board, a back board, a bottom reinforced board and a fixing bolt hole, wherein each component is welded to form a metal frame with a cross section which is similar to be rectangular; the upper end of the front board is bent forwards to form an upper part hook overlap-joint face; a panel is welded in front of the lower middle part of the front board and is used for connecting the metal frames at the bottom in a reinforced manner; the bolt fixing holes further are symmetrically formed at the middle positions of the front board; and meanwhile, a plurality of cable head fixing positions are distributed on the front board. The cable connection device provided by the invention has the advantages of reasonable structure, simplicity and convenience in welding assembly, and high device reliability.
Description
Technical field
The invention belongs to the smelting equipment technical field, particularly relate to a kind of hook lapping type ladle refining furnace conductive cross arm cable connecting arrangement.
Background technology
the three-phase conductive cross arm cable connecting arrangement of existing ladle refining furnace adopts the side to weld and add 4 of ends M18 bolt and fixes, in order to guarantee that conductive cross-sectional area satisfies the situ production requirement, adopt the welding of fillet weld copper steel, every have 4 water-cooled cables (gross weight 6650kg) mutually, because welding stress is concentrated, during heavier the and production run of 4 water-cooled cable weight of every phase, conductive cross arm moves up and down frequently, after causing using for some time, the phenomenon of sealing-off can occur in fillet weld, and then 4 of ends bolt gravitate can produce arcing and lose efficacy, cause so again fillet weld aggravation heating cracking, whole device stressing conditions enters the final equipment scrapping of vicious cycle, can't use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hook lapping type ladle refining furnace conductive cross arm cable connecting arrangement, and is stressed unreasonable to solve original device, holds flimsy problem.
the technical solution adopted for the present invention to solve the technical problems is: a kind of hook lapping type ladle refining furnace conductive cross arm cable connecting arrangement, comprise both sides and top web plate, header board, rear plate, bottom stiffener, four bolts, described both sides and top web plate, weld the also metal architecture of the similar rectangle of Formation cross-section between front and rear panels, header board upper end bending forward forms top hook faying surface, the place ahead welding one bottom stiffener of position, header board middle and lower part, header board middle part also symmetry has a bolt mounting holes, also be distributed with some cable head fixed bits on header board.
Described header board is linked up with faying surface, bottom stiffener by top and is welded and fixed with ladle refining furnace conductive cross arm above and below respectively, and the header board middle part is bolted the end that the ladle refining furnace conductive cross arm is installed.
Beneficial effect
The present invention adopts rational force structure, has reduced the stressed of end angular commissure; Under same current water conservancy diversion area, effectively reduce the end angular throat thickness, reduce end welding stress and welding job amount, reduce the integral solder requirement; Change shearing connection into the compression type connection and can avoid the weld cracking phenomenon, improve reliability.

Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
as Fig. 1, Fig. 2 and shown in Figure 4, a kind of hook lapping type ladle refining furnace conductive cross arm cable connecting arrangement, comprise both sides and top web plate 1, header board 2, rear plate 3, bottom stiffener 4, 4 bolts 5, ladle refining furnace conductive cross arm 6, cable head fixed bit 7, described both sides and top web plate 1, weld the also metal architecture of the similar rectangle of Formation cross-section between header board 2 and rear plate 3, header board 2 upper ends bending forward form top hook faying surface, the place ahead welding one bottom stiffener 4 of header board 2 positions, middle and lower part, header board 2 middle parts also symmetry have 4 bolt mounting holes, also be distributed with some cable head fixed bits 7 on header board 2.
Described header board 2 is linked up with faying surface, bottom stiffener 4 by top and is welded and fixed with ladle refining furnace conductive cross arm 6 above and below respectively, and header board 2 middle parts are by the end of bolt 5 fixed installation ladle refining furnace conductive cross arms 6.
Each sheet material matter of above-mentioned cable connecting arrangement all adopts the thick copper sheet of 20mm, and the angle seam place of 4 of top hook faying surfaces, bottom stiffener carries out brazing, and throat thickness 10mm has so just increased conductive cross-sectional area.
