Description
Technical field
The utility model relates to graphite electrode mineral hot furnace apparatus field, especially a kind of torque spanner for connecting graphite electrode.
Background technology
The graphite electrode diameter that large-scale mineral hot furnace uses is greater than 500 ㎜, and length is greater than 2000 ㎜, and quality is greater than 1000 ㎏, and graphite electrode needs its spreading in use for some time, thus ensures that the continuation of electrode uses.Graphite electrode spreading is higher to spreading required precision because of electrode characteristic, operates by artificial spreading when operating space is limited.Therefore torque spanner desired strength is high, easy to use, and spreading is laborsaving to save time, safety, economical.
The special torque spanner of former connection large-diameter graphite electrode is semi-circular shape toroidal torque spanner, in spreading electrode process, fixes by artificial pushing torque pinch bar, the screw thread at armrest handle moment loading locking electrode contact position.When connecting graphite electrode, by execute-in-place position limitation, torque spanner can not rotate freely, half-turn can only be rotated at every turn, then re-move torque spanner, again reorientate, repetitive cycling turns to till both ends of the surface contact with each other, whole spreading process wants running torque ring more than 20 time, spreading electrode needs 60 minutes, not only very big, the consuming time length of labour intensity, and wants power failure operation due to electrode during spreading, electric furnace operating rate can be reduced, increase the power consumption after electric furnace recovery power transmission.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of when graphite electrode spreading, only needs once mounting positioning instant can rotate and then complete the torque spanner for connecting graphite electrode of whole electrode installation continuously.
The utility model solves the technical scheme that its technical problem adopts: for connecting the torque spanner of graphite electrode, comprise spanner unit, the handle that described spanner unit is connected to described semicircle cambered surface frame by semicircle cambered surface frame and at least one is formed, described spanner unit is two, described two spanner unit are fastened by connector and are integrated, two semicircle cambered surfaces are configured to the electrode collar of ring-type, are arranged symmetrically with between the handle of the correspondence of described two spanner unit in 180 °.
Further, each spanner unit all has two handles, and described handle is all arranged near connector.
Further, the internal face of two semicircle cambered surface framves is all fixedly installed non-slipping block.
Further, described non-slipping block is provided with anti-skidding teeth groove, the anti-skidding teeth groove direction of adjacent two non-slipping blocks is contrary.
Further, the outside wall surface of described semicircle cambered surface frame is provided with reinforcing ring.
Further, described connector is connecting bolt.
The beneficial effects of the utility model are: when reality uses, and are first opened by two spanner unit and by treating that the graphite electrode of spreading is socketed in two semicircle cambered surface framves, then buckle connector.Now, the electrode collar of ring-type that is just configured to by two semicircle cambered surfaces completely of whole graphite electrode be socketed fastening.Ensuing, operating personnel only need according to operational procedure during graphite electrode spreading, hold handle and rotate, due to no matter how electrode collar, how rotating operation personnel more conveniently can hold handle, so without the need to can only half-turn be being rotated as traditional spanner, but can once mounting be realized, the effect of continuous cycle rotation.The utility model is particularly useful for using when the burrstone mill spreading to graphite electrode mineral hot furnace.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Be labeled as in figure: reinforcing ring 1, semicircle cambered surface frame 2, handle 3, connector 4, non-slipping block 5, electrode collar 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
The torque spanner for connecting graphite electrode as shown in Figure 1, comprise spanner unit, the handle 3 that described spanner unit is connected to described semicircle cambered surface frame 2 by semicircle cambered surface frame 2 and at least one is formed, described spanner unit is two, described two spanner unit are fastened by connector 4 and are integrated, two semicircle cambered surface framves 2 form the electrode collar 6 of ring-type, are arranged symmetrically with between the handle 3 of the correspondence of described two spanner unit in 180 °.
When reality uses, first two semicircle cambered surface framves 2 being opened, until the graphite electrode of column being socketed on after between two semicircle cambered surface framves 2, then two spanner unit being integrated by connector 4 fastening.Now, two semicircle cambered surface framves 2 form the electrode collar 6 of ring-type, firm being clamped by graphite electrode of described electrode collar 6.Ensuing, the terminal pad of graphite electrode end namely by grip hand 3 rotating spanner unit, thus turns to together by operating personnel, thus achieves once mounting, continuous cycle rotation and disposable complete graphite electrode install operation.Be arranged symmetrically with in 180 ° between handle 3 due to correspondence, namely the angle state that no matter electrode collar 6 rotates how, operating personnel can find the handles 3 closed on easily, thus are rotated further above-mentioned electrode collar 6, and this improves the technological deficiency can only rotating half-turn overcoming legacy equipment.
Certain, in order to further realize rotating easily, can select such scheme: each spanner unit all has two handles 3, described handle 3 is all arranged near connector 4.As shown in Figure 1, such modified node method has following benefit: one is can start easily to rotate after the fastening completing connector 4, after the fastening of i.e. connector 4, operating personnel can find handle 3 smoothly near connector 4, thus carry out rotating operation; Two are the increase in handle 3 quantity being arranged in semicircle cambered surface frame 2 periphery, also can bring convenience when rotating operation.
Because graphite electrode surface lubricity is better, cambered surface fixed mount plane is smooth, for preventing spanner from sliding when rotational lock, ensureing handling safety, can select all to be fixedly installed non-slipping block 5 on the internal face of two semicircle cambered surface framves 2.As shown in Figure 1, non-slipping block 5 directly contacts with graphite electrode, thus effectively prevents slip when rotating.Certain, further, can select to arrange anti-skidding teeth groove on non-slipping block 5, the anti-skidding teeth groove direction of adjacent two non-slipping blocks 5 is contrary.The skidproof effect of such improvement is better.
In addition, during in order to ensure to rotate, the rigidity of semicircle cambered surface frame 2, can be provided with reinforcing ring 1 in the outside wall surface of described semicircle cambered surface frame 2.As shown in Figure 1, reinforcing ring 1 considerably increases the rigidity of semicircle cambered surface frame 2, thus improves the ability of semicircle cambered surface frame 2 resistance to deformation.
In conjunction with practical experience, under fastening the prerequisite of effect at guarantee two semicircle cambered surface framves 2, simplify dependency structure, described connector 4 can be designed to connecting bolt.So not only can realize the fastening of two semicircle cambered surface framves 2 very easily and open, also greatly reducing cost during making.
