firstly, the method comprises the following steps: the traditional hanger rods (1) are plate-type, C-shaped, the process for manufacturing the hanger rods (1) is complex, the hanger rods (1) are cut from a stainless steel body, a reinforcing plate (13) is welded at the tops of the two hanger rods (1), holes need to be drilled after the reinforcing plate (13) is welded, finally the hanger rods are bent to form the C-shaped hanger rods, the manufacturing period of the whole process is long, the two hanger rods (1) and the reinforcing plate (13) need to be integrally and completely replaced when overhauling and replacing, time and labor are consumed, and the cost is high;
secondly, the method comprises the following steps: the bending manufacture of the stainless steel plate can influence the integral hanging height of the contact element if the processing is slightly deviated, and the height can not be adjusted;
thirdly, the method comprises the following steps: in the using process, the vibration generated by repeated pressure release of the electrode system easily causes the suspension rod (1) to collide with the vertical copper pipe, so that the phenomenon of fire is caused;
fourthly: if the welding size of the electrode shell is not in place, the electrode shell rib plate is easy to contact with the suspender (1) (the suspender is made of a plate type and is difficult to insulate), the phenomenon of sparking is easy to occur when the friction is large, the electrode shell is damaged after sparking, electrode paste in the electrode shell flows out, and all devices at the bottom of an electrode system are not insulated seriously, so that the starting rate of equipment is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects of the background art and providing a hanging structure of a contact element for a submerged arc furnace, which has high strength, good insulation property, can obviously reduce the phenomenon of fire and can adjust the hanging height.
In order to achieve the above-mentioned objects of the utility model, the technical scheme of the utility model is that:
a hanging structure of a contact element for a submerged arc furnace comprises a suspender, wherein the suspender is round steel with threads on the outer wall of the upper end, and the lower end of the suspender penetrates through the top surface of a C-shaped connecting plate and is then welded with the connecting plate; the upper end of the hanger rod passes through the flange and is fixed by a first nut and a second nut in two pairs; the connection plate is connected with the contact element at the bottom surface.
Preferably, the first insulating sleeve is sleeved on the suspension rod.
Preferably, a second insulating sleeve is arranged between the suspension rod and the flange.
Preferably, a first insulating pad is arranged between the first nut and the flange.
Preferably, a second insulating pad is arranged between the second nut and the flange.
Preferably, the connecting plate and the contact element are fixedly connected by a connecting bolt.
Preferably, a rib plate is welded between the top surface and the side surface of the connecting plate.
The utility model has the advantages that:
firstly, the method comprises the following steps: the shape of the suspender is changed, the traditional plate-type C-shaped suspender is changed into round steel with threads at one end, the processing technology of the suspender is simple, drilling and bending are not needed, the manufacturing period is short, and the strength is high;
secondly, the method comprises the following steps: one end of the round steel is provided with threads and is fixed by a first nut and a second nut which are opposite to each other, and the structure is convenient for adjusting the hanging height of the contact element;
thirdly, the method comprises the following steps: the insulating sleeve I is sleeved on the suspender, the insulating sleeve II is arranged between the suspender and the flange, the insulating pad I is arranged between the nut I and the flange, and the insulating pad II is arranged between the nut II and the flange, so that the whole hanging structure has good insulativity, even if the electric furnace electrode system generates vibration when ascending and descending and collides with the electrode shell rib plate and the vertical copper pipe due to the existence of the insulating pipe (the suspender is made of round steel, and the contact area is small when the suspender is in contact with the insulating pipe), the sparking phenomenon is greatly reduced, the service life is greatly prolonged due to good insulating protection, and the starting rate of equipment is improved;
fourthly: during daily maintenance, the suspender can be replaced singly, the maintenance time is greatly reduced due to the convenient replacement, the labor amount is reduced, and the cost is also saved.
