Abstract
The utility model relates to a driving electrode rotation lifting device of a front wheel of a dual work station ladle furnace, comprising a conductive cross arm, a guide wheel group, an electrode column, a rotating rack of the electronic column, a rotating seat, an arc rail, a vertical hydraulic cylinder and a horizontal hydraulic cylinder. The electronic column is positioned between an upper layer of guide wheel and a lower layer of guide wheel of the rotating rack of the electronic column, and the vertical hydraulic cylinder drives vertically the electronic column to rise or fall. The small end of the rotating rack of the electronic column is provided with the rotating seat, and the two ends of the big end of the rotating rack of the electronic column are provided with driving wheels as front wheels. The driving electrode rotation lifting device has a driving point on the wheels, thus having very small horizontal acting force to the rotating seat. As the driving point of the rotation lifting device is at the wheels, thus being capable of well coordinating the parameters of the radius R of the arc rail and the length L of the conductive cross arm and leading the mechanical property of the device to be more reasonable.
Description
Technical field
The utility model relates to the external refining device design of metallurgy industry, and particularly a kind of double ladle furnace (LF) adopts the electrode rotating lifting gear of front vehicle wheel type of drive.
Background technology
Double ladle furnace (LF) electrode rotating lifting gear is a kind of heated by electrodes equipment, it can by horizontally rotate, the electric-pole horizontal arm of VTOL (vertical take off and landing), realize the ladle that is positioned at two stations heated by electrodes that hockets.A ladle is in the station heat-treatment process of LF, and another handles station can be to the All Jobs of another ladle except that heating, and this decoration form has been saved subsidiary operation time, has improved the operating efficiency of LF.
Referring to Fig. 1, existing double-station LF electrode rotating lifting gear adopts small end hydro-cylinder pushing tow type of drive, and this kind double-station LF furnace mainly is made up of conductive cross arm 1, guiding wheels 2, electrode mast 3, electrode mast swivel mount 4, rotary seat 5, driven wheel 6, arc track 7, vertical hydraulic cylinder 8 and horizontal hydraulic cylinder 9.
Electrode mast 3 is arranged in the two-layer guiding wheels 2 up and down that are installed in electrode mast swivel mount 4, is driven by vertical hydraulic cylinder 8, can rise or descend by vertical drive electrode mast 3.The small end of electrode mast swivel mount 4 is equipped with rotary seat 5, and driven wheel 6 is equipped with at the two ends of another big end.Small end galianconism r is equipped with a horizontal hydraulic cylinder 9 in the place.Under the effect of horizontal hydraulic cylinder 9, electrode mast swivel mount 4 can be around rotary seat 5 rotations, and two driven wheels 6 of electrode mast swivel mount 4 big ends can move along arc track 7.
The type of drive of above-mentioned rotating lifting gear is to be promoted by the horizontal hydraulic cylinder 9 that is positioned at turning point galianconism r place, makes the big quality point that concentrates on the long-armed R of place move along arc track 7, and rotary seat 5 places are subjected to bigger horizontal applied force.As shown in fig. 1, prior art is to be drive source by the horizontal hydraulic cylinder 9 that is positioned at small end galianconism r, makes the big quality point that is positioned at the long-armed R of big end place move along arc track 7, and 5 places can produce bigger horizontal applied force at rotary seat.
When big electric current passes through, sizable electromagnetic force is arranged between conductive cross arm, can cause the horizontal vibration of electrode tip, the length L of the conductive cross arm of its amplitude size and electrode mast connecting end front and closely related by size of current is so wish that anterior L is short as far as possible.But, require front end L short as far as possible, radius R that then must corresponding increase arc track, the suspended portion of vertical hydraulic cylinder is installed down can in the arc basis of arc track, passes through to guarantee the electrode mast swivel mount, and R increases, then the lever ratio of R/r increases, and this hydraulic action that just requires to be positioned at small end galianconism r also will increase.Therefore, this hydro-cylinder pushing tow drive form wishes that again turning radius R is as far as possible little, and this is a pair of contradiction, has produced problem thus.
The utility model content
Task of the present utility model provides a kind of improved double ladle furnace front vehicle wheel drive-type electrode rotating lifting gear, it has solved prior art is to be that drive source makes big quality point move along arc track by horizontal hydraulic cylinder, thereby can produce the problem of big horizontal applied force at the rotary seat place.
Technical solution of the present utility model is as follows:
A kind of double ladle furnace front vehicle wheel drive-type electrode rotating lifting gear, it comprises conductive cross arm, guiding wheels, electrode mast, electrode mast swivel mount, rotary seat, arc track, vertical hydraulic cylinder and horizontal hydraulic cylinder, electrode mast is arranged in the two-layer guiding wheels up and down that are installed in the electrode mast swivel mount, rise or descend by vertical hydraulic cylinder vertical drive electrode mast, the small end of described electrode mast swivel mount is equipped with rotary seat, and the driving wheel as front vehicle wheel is equipped with at the big end two ends of electrode mast swivel mount.
The drive point of double ladle furnace front vehicle wheel drive-type electrode rotating lifting gear of the present utility model is on wheel, and is therefore quite little to the horizontal applied force of rotary seat.Because the drive point of this rotating lifting gear at the wheel place, therefore can be coordinated the parameter of arc track radius R and conductive cross arm length L well, makes the mechanical characteristic of equipment more become reasonable.
Description of drawings
Fig. 1 is the structural representation that existing double-station LF electrode rotating lifting gear adopts small end hydro-cylinder pushing tow type of drive.
Fig. 2 is the structural representation of a kind of double ladle furnace front vehicle wheel drive-type electrode rotating lifting gear of the present utility model.
Embodiment
Referring to Fig. 2, the utility model is a kind of double ladle furnace front vehicle wheel drive-type electrode rotating lifting gear, and it mainly is made up of conductive cross arm 1, guiding wheels 2, electrode mast 3, electrode mast swivel mount 4, rotary seat 5, arc track 7, vertical hydraulic cylinder 8 and horizontal hydraulic cylinder 9.
Electrode mast 3 is arranged in the two-layer guiding wheels 2 up and down that are installed in electrode mast swivel mount 4, is risen or is descended by vertical hydraulic cylinder 8 vertical drive electrode masts 3.
The small end of electrode mast swivel mount 4 is equipped with rotary seat 5, and the driving wheel 10 as front vehicle wheel is equipped with at the big end two ends of electrode mast swivel mount 4.Driving wheel 10 has drive unit.Driving wheel 10 rotations then can drive the entire electrode rotating lifting gear around rotary seat 5 rotations.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
