Abstract

The utility model relates to a tighten adjusting device for electric furnace electrode machinery, which is used for producing an electric furnace in a metallurgy enterprise, and producing calcium carbide in chemical industry enterprise. A friction ring and a worm wheel, and a worm drive a screw rod locking mechanism to make the interoperation. An electric furnace electrode is provided with the friction ring to match an electric machine arranged on am electrode jacket to drive the worm wheel and the screw rod to turn to influence the draw rod and a conical ring to move up and down to lock or loosen a copper tile, and fix or loosen the electrode to realize the length adjustment of the electric furnace electrode.

Description

Tighten adjusting device for electric furnace electrode machinery

The utility model relates to the electric furnace electrode adjusting device, and particularly electric furnace electrode machinery is held adjusting device tightly.

In the production process of the iron alloy electric furnace of smelter, chemical enterprise calcium carbide electric furnace, often need to regulate the length of electric furnace electrode.The method of current adjusting electric furnace electrode has manual adjustment, hydraulic mechanism to regulate three kinds of gentle press mechanism adjustings.Though these methods can be regulated the length of electric furnace electrode, satisfy electric furnace production technology needs, but have weak point: the former labour intensity at first of manual adjustment method is big, hydraulic mechanism is adjusted in and often occurs the oil impregnate out-of-control phenomenon under the hot conditions, pneumatic adjusting need be joined special long-term operation air compressor machine, energy consumption is big, inconvenient operation.

The utility model purpose is to provide a kind of electric furnace electrode machinery to hold adjusting device tightly, and the locking electrode satisfied the electric furnace manufacturing technique requirent when it can regulate electric furnace electrode length rapidly, exactly.

Scheme of the present utility model is: adorn a drag ring on electrode, make itself and interelectrode frictional force be slightly less than the weight of electrode, when needing to regulate the length of electrode ［ 1 ］ in the production process, starter motor ［ 4 ］, by V belt ［ 11 ］ transmission worm screw ［ 5 ］, worm gear ［ 6 ］, screw mandrel ［ 7 ］, driving pull bar ［ 8 ］ affects conical ring ［ 9 ］ to move up and down, unclamp or lock brasses ［ 10 ］ and regulate electric furnace electrode length on demand, when needing electrode ［ 1 ］ toward downward modulation length, unclamp brasses ［ 10 ］, the electrode certain-length that falls automatically, promptly lock brasses, need to carry certain-length on the electrode, go ahead simultaneously together with electrode by hoist engine drive overcoat ［ 3 ］ and move.

The utility model relies on screw mandrel to regulate locking, does not need frequent starter motor, reduces power consumption, but adapts to the high temperature live line working, and is simple in structure, low cost of manufacture.

Accompanying drawing is the utility model operating state front view, it has described an embodiment that 1800KVA is above, with reference to accompanying drawing, the utility model is by drag ring ［ 2 ］, corrector loop ［ 12 ］, electrode jacket ［ 3 ］, flange ［ 13 ］, brasses ［ 10 ］, conical ring ［ 9 ］ and power transmission regulating system are formed, this system is by motor ［ 4 ］, worm screw ［ 5 ］, worm gear ［ 6 ］, screw mandrel ［ 7 ］, pull bar ［ 8 ］ is formed, and be fixed on the support of the electrode jacket of being located on the flange ［ 12 ］［ 3 ］, the a pair of brasses of being located in the conical ring ［ 9 ］ hangs on the flange ［ 12 ］, be located at the vertical degree that corrector loop ［ 12 ］ between drag ring ［ 2 ］ and the overcoat ［ 3 ］ is used for correcting electrode ［ 1 ］, pull bar ［ 8 ］ lower end connects conical ring ［ 9 ］, last termination screw mandrel ［ 7 ］, screw mandrel ［ 7 ］, worm gear ［ 6 ］ is set on the worm screw ［ 5 ］ successively, drive worm screw ［ 5 ］ by motor ［ 4 ］ by belt ［ 11 ］, worm gear ［ 6 ］, screw mandrel ［ 7 ］, pull bar ［ 8 ］ running, conical ring is moved up and down, reach the purpose of holding tightly or unclamping electrode ［ 1 ］.

Keep being slightly less than the frictional force of electrode weight between drag ring ［ 2 ］ and the electrode ［ 1 ］, when starter motor ［ 4 ］, by belt ［ 11 ］ transmission worm screw ［ 5 ］, worm gear ［ 6 ］, screw mandrel ［ 7 ］, affect pull bar ［ 8 ］, conical ring ［ 9 ］ to move up and down, lock or loosen brasses ［ 10 ］ and reach locking or loosen electrode, when conical ring ［ 9 ］ moves down, brasses ［ 10 ］ unclamps, electrode ［ 1 ］ certain length that falls automatically, motor steering affects on the conical ring ［ 9 ］ and moves, brasses ［ 10 ］ locking.If it is long that electrode falls, can start hoist engine electrode jacket ［ 3 ］ and electrode ［ 1 ］ are up carried simultaneously, keep suitable length, satisfy manufacturing technique requirent.

The novel electric furnace electrode through the above capacity of many cases 1800KVA of this reality is regulated, locking is implemented, and technical matters is feasible.
