Abstract
The utility model discloses a graphite electrode mounting tool which comprises a handle and a clamp ring. The handle includes a left handle and a right handle. The clamp ring includes a left clamp ring and a right clamp ring. The left handle is connected with the left clamp ring. The right handle is connected with the right clamp ring. The left clamp ring is hinged with one end of the right clamp ring. The other end of the left clamp ring bends outwardly, and a clamp groove is formed in the bending part. A hook is mounted at the other end of the right clamp ring through a bolt. The other end of the hook is disposed in the clamp groove to allow the left clamp ring and the right clamp ring to be connected to form a circular ring. The graphite electrode mounting tool has the advantages that the annular clamp structure is used, and a graphite electrode is clamped by the annular clamp and fastened by a top screw on the annular clamp; due to the fact that slippage exists between the annular clamp and the graphite electrode, a friction rod for increasing the relative friction force between the annular clamp and the graphite electrode is further disposed in the annular clamp, labor saving and time saving can be achieved during butt joint graphite electrode mounting performed by workers, and threads at a connection remains intact.
Description
Technical field
The utility model relates to a kind of graphite electrode erecting tools.
Background technology
Graphite electrode is applied to electronics arc light smelting furnace (abbreviation electric arc furnaces), and because of the needs of manufacturing and using, the electrode using is in practice longer, with many noncontinuous electrodes, through conical graphite joint, is formed by connecting.Quality of connection between graphite electrode is said direct affect electric arc furnaces energy utilization rate and normal melting work.In order to ensure good use state, in the installation of graphite electrode with while changing, control torsional moment size extremely important.And correctly tightening up of carbon, graphite electrode is the efficiency that known meeting increases energy electric arc furnaces.
The instrument that present smelting industry is tightened graphite electrode has a variety of.Conventional two agrafes are respectively clamped an electrode and are tightened graphite electrode.Its screwing force mainly leans on master workers' experience like this.Tighten graphite electrode torsional moment used not too much or too small, torsional moment is crossed large electrode and is easily twisted off or produce internal injury (underbead crack); If torsion is too small, may cause the loose contact of electrode junction and produce electric arc, make contact position sharply rubescent oxidation attenuate and fracture (also can affect energy utilization rate).So when the installation of graphite electrode and replacing, control torsional moment size just very important.When installing and changing graphite electrode, lean on technology, by experience, be not all right.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and is convenient to the three-dimensional socket of a kind of rotatable control that control and processing safety are high.
A kind of graphite electrode erecting tools, comprise handle and snap ring, described handle is left handle and right handle, described snap ring is left snap ring and right snap ring, described left handle is connected with left snap ring, described right handle is connected with right snap ring, one end of left snap ring and right snap ring is hinged, the other end outward of left snap ring, described bending place is provided with draw-in groove, the other end place of described right snap ring is provided with a hook by bolt, and the other end of hook is placed in draw-in groove, left snap ring and right snap ring is connected together and form an annular.
On the inner arc surface of left snap ring and right snap ring, be provided with at least two cylindricality friction levers.
On right snap ring, be provided with through hole, through hole is provided with nut, is provided with jackscrew bar in nut.
The utility model has the advantages that: the utility model adopts annular snap structure, by annular snap, graphite electrode is blocked, by the jackscrew bar in annular snap, graphite electrode is clamped again, in the process of installing, can produce between due to annular snap and graphite electrode and skid, therefore in annular snap, be also provided with for increasing the friction lever of relative friction forces between them, workman is laborsaving when abutting joint graphite electrode like this saves time again, make the screw thread of junction intact, for safety, the high efficiency of smelting industry are provided convenience.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment: a kind of graphite electrode erecting tools as shown in the figure, comprise handle and snap ring, described handle is left handle 1 and right handle 11, described snap ring is left snap ring 3 and right snap ring 6, described left handle 1 is connected with left snap ring 3, and described right handle 11 is connected with right snap ring 6, and left snap ring 3 is hinged with one end of right snap ring 3, the other end outward of left snap ring 3, described bending place is provided with draw-in groove 9.The other end place of described right snap ring 6 is provided with a hook 10 by bolt 7, and the other end of hook 10 is placed in draw-in groove 9, left snap ring 3 and right snap ring 6 is connected together and form an annular.
On the inner arc surface of left snap ring 3 and right snap ring 6, be provided with at least two cylindricality friction levers 2.
At right snap ring 6, be provided with through hole 8, through hole 8 places are provided with nut 4, are provided with jackscrew bar 5 in nut 4.The rear end of jackscrew bar also can be provided with handle.Said structure also can be arranged on left snap ring 3 as required.
