Description
Technical field
The utility model relates to a kind of special spanner, relates in particular to a kind of spreading electrode spanner.
Background technology
The electric furnace that current domestic steelshop is used or refining furnace graphite electrode spreading hand-operated tools have hood type and two kinds of tool types of Wrench-type.Hood type instrument is first circular anchor ear to be fixed on electrode, then is welded on 3～4 handles (shape is as steamer rudder) on anchor ear by rotation, and electrode is tightened to spreading.Because its handle is welded on anchor ear, be to strengthen structural strength, anchor ear plate should have certain thickness, therefore make instrument heavier, has limited in addition the length of turning handle due to its design feature, therefore tightens operation more painstaking.Wrench-type instrument is made up of jaw and pinch bar, when operation, first its moving jaw is vised to electrode, then tightens spreading electrode by rotating spanner handle.
Application number is that the Chinese patent of 201120228495.5 (date of application is on June 30th, 2011) discloses a kind of special spanner for connecting cylindrical graphite electrodes, comprise train wheel bridge, handle, fastening teeth, clamping screw, lower plate, split pin, pin composition, its train wheel bridge one end is fixedly connected with by pin with lower plate one end, the train wheel bridge other end and lower plate other end correspondence position are provided with screwed hole, are flexibly connected by clamping screw.The deficiency of its existence is: anchor ear is fixedly that to open and close bolt and nut on mouthful edges plain existing by being contained in respectively anchor ear two on electrode, and the mounting or dismounting time is long, not easy to operate, and needs auxiliary tools.
Summary of the invention
The utility model provides a kind of spreading electrode spanner, and its retaining mechanism can be realized quick aligning and connects and lock, simple in structure, easy to operate, time saving and energy saving, from heavy and light, and long service life.
In order to achieve the above object, the utility model is realized by the following technical solutions:
A kind of spreading electrode spanner, comprises moving jaw, handle and retaining mechanism, and moving jaw is Split type structure, and its two ends are connected with retaining mechanism by bearing pin is hinged respectively, and handle is distributed on moving jaw circumferencial direction; It is characterized in that, described retaining mechanism is made up of the piece that is articulated and connected, draw-in groove contiguous block, screw rod, swivel nut and crank, and be articulated and connected piece and draw-in groove contiguous block are fixed on moving jaw opening both sides, and screw rod is hinged with the piece that is articulated and connected, swivel nut is sleeved on screw rod, and swivel nut afterbody is installed crank.
Described bearing pin hinged place and retaining mechanism are oppositely arranged, and between handle, angle is 20～25 °.
Reinforcement is established in described handle and both sides, moving jaw junction, and handle end is established antiskid glue sleeve.
Described moving jaw inwall is established several clamps.
Described moving jaw is cast iron quality.
Compared with prior art, the beneficial effects of the utility model are:
1) retaining mechanism of the present utility model can be realized quick aligning connection and locking, does not need additional other instrument;
2) simple in structure, easy to operate, time saving and energy saving;
3) moving jaw adopts cast iron quality, little to graphite electrode damage;
4) from heavy and light, long service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the I portion amplification view of Fig. 1.
In figure: 1. moving jaw 2. clamp 3. handle 4. hinging pin shaft 5. retaining mechanism 6. Anti-slip cover 7. reinforcements 8. piece 9. bolt 10. draw-in groove contiguous block 11. screw rod 12. swivel nut 13. rivet 14. cranks that are articulated and connected
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1-Fig. 2, it is structural representation of the present utility model, a kind of spreading electrode of the utility model spanner, comprise moving jaw 1, handle 3 and retaining mechanism 5, moving jaw 1 is Split type structure, its two ends are connected with retaining mechanism 5 by bearing pin 4 is hinged respectively, and handle 3 is distributed on moving jaw 1 circumferencial direction; Described retaining mechanism 5 is made up of the piece 8 that is articulated and connected, draw-in groove contiguous block 10, screw rod 11, swivel nut 12 and crank 14, be articulated and connected piece 8 and draw-in groove contiguous block 10 is fixed on moving jaw 1 opening both sides, screw rod 11 is hinged with the piece 8 that is articulated and connected, swivel nut 12 is sleeved on screw rod 11, and swivel nut 12 afterbodys are installed crank 14.
Described bearing pin 4 hinged places and retaining mechanism 5 are oppositely arranged, and between handle 14, angle is 20～25 °.
Described handle 3 is established reinforcement 7 with moving jaw 1 both sides, junction, the handle 3 ends sliding sleeve 6 of setting up defences.
Described moving jaw 1 inwall is established several clamps 2.
Described moving jaw 1 is cast iron quality.
When use, a new electrode is sling with crane, the utility model is enclosed within to electrode distance screw thread 500mm place, to be articulated and connected at retaining mechanism 5 places piece 8 and draw-in groove contiguous block 10 aligns, the other end that one end is fixed on to the screw rod 11 being articulated and connected on piece 8 is put into the draw-in groove of draw-in groove contiguous block 10, the crank 14 that shake swivel nut 12 afterbodys connect with rivet, crank 14 is with movable snail sleeve 12 and screw rod 11 that relative motion occurs, thereby moving jaw 1 is locked at interface.New electrode is hung and treats receiving electrode top, and decline crane hook, stops at a distance of about 100mm to two electrode contact surfaces.The new electrode of low speed slow decreasing, to two electrode thread contacts, along with the new electrode that declines, electrode is rotatably connected.After two electrode contact surface contacts, reverse 1/4 week, firmly electrode is screwed together by operating personnel.
