Description
Technical field
This utility model relates to the fixing device of a kind of electric-pole horizontal arm, particularly relates to a kind of LF stove electric-pole horizontal arm and laterally fixes
Device.
Background technology
Clamp each of three electrodes utilization respectively with each of three electrodes transverse arm when LF stove produces and be contained in box type column inner cylinder under transverse arm
Flexible, make electrode parallel insert vertically from above in molten steel, reach the effect of electric arc heated molten steel.The transverse arm of existing LF stove relies on
Three screw rods on column are vertically fixed, because electrode and electric-pole horizontal arm deadweight are heavier, simple these 3 screw rods of dependence are difficult to electricity
Pole transverse arm and column compact siro spinning technology, in production and application, be to need by electric-pole horizontal arm to electrode by high-tension electricity, so again can not
Simply electric-pole horizontal arm is directly fixedly connected with metal objects such as screw rods with column, otherwise easily causes high-tension electricity and put
Electricity, causes personnel to injure, and the vibration produced due to arcing between each of three electrodes and hyperthermia radiation easily make standing screw loosen
Cause transverse arm to produce lateral displacement, make the hole wall of trigonum on electrode touching bell, electrode can be made to produce with bell when motion
Rub and then make electrode fracture, bringing the biggest puzzlement to production direct motion and plant maintenance aspect.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of electric-pole horizontal arm lateral fixing device, prevents electrode horizontal
Arm generation transverse shifting is skimmed disconnected causing and is produced interruption.
This utility model solves its technical problem the technical scheme is that LF stove electric-pole horizontal arm lateral fixing device,
Including fixed plate, push rod, nut, insulation board, middle pad, locating piece.Between both sides of the edge, column upper end and electric-pole horizontal arm each right
Claiming to be provided with two set lateral fixing devices, the fixed plate of lateral fixing device is fixedly mounted on column, and push rod is from fixed plate
Female thread in be screwed into, equipped with nut inside fixed plate, the diameter of nut is slightly less than the diameter of fixed plate, and nut is horizontal near electrode
Arm side is provided with middle pad, and equipped with felt pad between middle pad and electric-pole horizontal arm, felt pad both sides are solid on electric-pole horizontal arm
Surely there is locating piece.
The main table of this utility model advantage is: simple in construction, small investment, safe and reliable.

Detailed description of the invention
This utility model embodiment is: seeing Fig. 1, Fig. 2, LF stove electric-pole horizontal arm lateral fixing device, including fixed plate
41, push rod 42, nut 43, insulation board 44, middle pad 45, locating piece 46.Between both sides of the edge, column 2 upper end and electric-pole horizontal arm 1
Respectively being symmetrically installed with two set lateral fixing devices 4, the fixed plate 41 of lateral fixing device 4 is fixedly mounted on column 2, push rod 42
Being screwed in female thread from fixed plate 41, equipped with nut 43 inside fixed plate 41, the diameter of nut 43 is slightly less than fixed plate 41
Diameter, nut 43 is provided with middle pad 45 near electric-pole horizontal arm 1 side, equipped with insulation between middle pad 45 and electric-pole horizontal arm
Pad 44, felt pad 44 both sides are fixed with locating piece 46 on electric-pole horizontal arm 1.
This utility model in use, unclamps round nut 32 slightly, and regulation push rod 42 tightens circle after making electric-pole horizontal arm centering
Nut 32, holds out against 4 push rods 42 and makes insulation board 44 be close to electric-pole horizontal arm 1 side, prevents toward fixed plate 41 direction fastening nut 43
The vibration produced during production causes push rod 42 to loosen.Felt pad 44 is vertical for prevent charged electric-pole horizontal arm 1 to be connected with the earth
Post 2 contact causes short circuit.Middle pad 45 is used for preventing push rod 42 from damaging insulation board 44 when rotation holds out against, and locating piece 46 is for solid
Determining felt pad 44 prevents felt pad about 44 from running.This utility model simple in construction, small investment, safe and reliable, effectively prevent electricity
Pole transverse arm generation transverse shifting.
