Abstract
The utility model relates to a multi-claw pipe joint for a water-cooling wire guide of an electric furnace, belonging to the mechanical field. The utility model is characterized in that a multiple claw conical head (1) is provided with a taper sleeve (2) outside, and the multiple claw conical head (1) and thetaper sleeve (2) are connected through a draw rod (12) and nuts. Two gapped water-cooling wire guides are sheathed on the multi-claw pipe joint relatively, and the draw rod is contacted with A surface of a flange plate tightly, ensuring the right connecting distance of a copper tube from an outlet terminal of a transformer to a cable joint.
Description
A kind of multijaw shape pipe joint is used for the water-cooled contact tube of electric furnace, belongs to mechanical field.
At present, the transmission system after the electric furnace second side goes out along with electric furnace develops to ultra high power, for satisfying the triangular layout of three phase mains, generally all adopts the water-cooled contact tube to conduct electricity.The water-cooled contact tube stretches out from the transformer outlet terminal, and frame is on cable joining, and electric current is passed on the big electric current water-cooled cable by cable joining.
The disadvantages of background technology part is: 1, the water-cooled contact tube is with multiform shape bent angle, when assembling at the scene, is difficult to guarantee the morpheme size and apart from size; When 2, assembling at the scene, be subjected to the erecting bed spatial constraints, the assembling difficulty is bigger.
The purpose of this utility model is to avoid the deficiency of above-mentioned background technology and a kind of multijaw shape pipe joint is provided, regulate water-cooled contact tube distance with multijaw shape pipe joint, guarantee the due length of water-cooled contact tube, guarantee copper pipe from the transformer outlet terminal to the correct connection distance between cable joining.
The purpose of this utility model can reach by following measure: multijaw conical head (1) is outer tapered sleeve (2), and multijaw conical head (1) is connected by pull bar (12), nut (13) with tapered sleeve (2).In the three-phase power transmission system of electric furnace, every all have 2～3 water-cooled contact tubes mutually.When install the water-cooled contact tube from the transformer line end have 30～50mm apart from the time, can use multijaw shape pipe joint to remedy, guarantee smooth installation.
The utility model is compared with background technique, and its advantage is:
1, the scene is easy for installation, can guarantee the installation dimension of water-cooled contact tube.
2, can compensate the coaxial deviation together of tube and tube.
3, easily adorn, easily unload, convenient maintenance.

Fig. 2 is multijaw conical head front view, and Fig. 3 is multijaw conical head figure side-looking Figure. Multijaw conical head (1) by ring flange (3), socket cap (4), Cone (5) forms, and has between socket cap (4) and the cone (5) and weakens Groove (6) has compression groove (7) on the cone (5), ring flange (3) On seal groove (8) is arranged, inwall has seal groove (9). Cone (5) Tapering is 1: 10～1: 30, and compression groove is 8～12. Sealing on the A face Ring recess (8) is interior, the sealing of medial surface grain circle (9) in-built O-ring seals, The cooling water of the water-cooling contact tube after guaranteeing to connect can not leak.
On the pipe wall of cone (5), in coaxial direction 8～12 pressures are arranged Contracting groove (7), the general wide 2～4mm of compression groove. When tapered sleeve (2) is enclosed within cone When body (5) is upper, because tapered sleeve (2) Xiang Zhuxin moves, make cone during installation Body (5) fully contacts with copper pipe, thereby adds large contact surface, makes contact resistance Reduce.
Compression groove adds man-hour, mills and weakens groove. Weaken the dark 5～8mm of groove (6), Tapered sleeve (2) extruding cone (5) is generally arranged when wall is thicker in cone (5) The time, weaken the extrusion stress at tapering place by weakening groove.
Fig. 4 is the tapered sleeve cutaway view. Tapered sleeve (2) by ring flange (10) and Cylinder (11) forms, and tapered sleeve medial surface tapering is 1: 10～1: 30. Flange On dish (3) and the ring flange (10) circular hole is arranged all, in order to pass through pull bar (12).
Multijaw conical head (1), tapered sleeve (2) material are copper material (T2).
Fig. 5 is pull bar and nut figure. Outside two cover multi-claw pipe joints (1) After putting tapered sleeve (2), screw rod is by ring flange (3) and ring flange (10) Circular hole, load onto clamp nut (13), dismounting nut (14), tight Gu nut (13) is adjacent on ring flange, screwing clamp nut (13) After, pipe joint guarantees that water-cooling contact tube normally moves.
Below in conjunction with most preferred embodiment the utility model is further set forth:
From the transformer terminal conductive and water cooled copper pipe φ 100mm * 20mm that comes out, when mounted, if going out end, transformer the 40mm spacing is arranged with the cable joining position, the water-cooled contact tube can be cut off, two multijaw conical heads are enclosed within outside the copper pipe, multijaw conical head flange plate φ 160mm * 18mm has 4 φ 20mm circular holes to be used for loading screw.Cone taper is 1: 30.Boring this microcephaly, to hold diameter be φ 112mm, on 12 compression grooves are arranged, wide 3mm, compression groove height are 100mm, the cylinder height is 30mm, weakens that groove is high to be 5mm.
The O RunddichtringO is embedded in the seal groove, two multijaw conical head A faces are adjacent to mutually, position when adjusting the normal running of water-cooled contact tube, this moment, tapered sleeve was enclosed within on the cone, and the tapered sleeve external diameter is φ 132mm, and the inner side surface tapering is 1: 30, circular diameter is φ 112mm in the termination, the high 70mm of tapered sleeve, flange plate are φ 160mm * 15mm, on the circular hole of 4 φ 20mm is arranged.4 φ 18mm pull bars penetrate in the flange circular hole of multijaw conical head and tapered sleeve, screw tightening nut, make taper sheath with the conehead lock ring outside the water-cooled contact tube.Water-cooled conductive steel steel pipe can put into operation, moves after 1～3 day, tightens up each position nut.When dismounting, rotation dismounting nut can be with the lax back dismounting of each position.
Multijaw shape pipe joint also is suitable for does the pipe coupling that the circulation common liq is used.
