Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the present invention is described in detail.
As shown in the figure, electric arc furnaces steel scrap stock ground automatical feeding system in the present embodiment, including magnetic disc suspending 8, delivery track with
And waggon；The magnetic disc suspending 8 has several, is correspondingly arranged at each across an A in stock ground 9；The delivery track includes level
Track 2 and inclined plane 6, the inclined plane 6 be arranged between stock ground 9 and electric arc furnaces 5 and with the arrival end phase of electric arc furnaces 5
It connects, is erected at across the correspondence of horizontal rail 2 respectively across A in stock ground 9 above inclined plane 6；The waggon includes walking
Horizontal feed vehicle 1 and the ramp skip car 3 on inclined plane 6 of walking, the horizontal rail 2 in horizontal rail 2 have
It two groups, is disposed in parallel in 9 center of stock ground and respectively will be divided into left and right two parts across a correspondence, reciprocal row in two groups of horizontal rails
Horizontal feed vehicle 1 is walked, and 1 blanking port of horizontal feed vehicle thereon can be connected to each other with the material receiving port of ramp skip car 3.
Specifically, horizontal rail 2 across stock ground 9 respectively across, the horizontal feed vehicle 1 walked in horizontal rail 2 is reachable
Stock ground it is arbitrary across, be arranged on respectively across magnetic disc suspending 8 only steel scrap 7 can be transported to horizontal feed vehicle across work at this
On, without transporting again, realize the charging of any position in horizontal rail 2 of horizontal feed vehicle 1.Two groups of side-by-side parallel setting
Horizontal rail 2 can run two horizontal feed vehicles, and two horizontal feed vehicles 1 are not interfere with each other, and can independently be completed in ramp
The charging work of truck 3, it is achieved thereby that the uninterrupted charging to ramp skip car 3.
As being further improved for said program, in stock ground 9 respectively across magnetic disc suspending 8 have two groups, correspondence sets up separately at two groups
At the one side of horizontal rail 2.Specifically, each in stock ground 9 is divided into a left side by two groups of horizontal rails 2 being set up in parallel across a correspondence
Right two parts, to it is each across for, every group of horizontal rail 2 corresponds to a magnetic disc suspending 8, in this way, the magnetic disc suspending 8 of each side can be direct
1 feeding of horizontal feed vehicle in corresponding horizontal rail 2, shortens the travel distance of magnetic disc suspending 8, has saved the feeding time.
As being further improved for said program, the stationary hopper 4 being arranged at 2 side of horizontal rail is further included, it is several
A stationary hopper 4 is laid with direction along horizontal rail 2 and is uniformly located at respectively across, and 4 blanking port of stationary hopper can be with horizontal feed vehicle 1
Material receiving port be connected to each other.Specifically, stationary hopper 4 hangs 8 steel scraps transferred available for temporary disk, convenient for 1 row of horizontal feed vehicle
It walks to quick feeding during 4 lower section of stationary hopper.Quantity and position by reasonable Arrangement stationary hopper 4, are allowed to and horizontal feed
Vehicle 1 and ramp skip car 3 are engaged, and magnetic disc suspending 8 can be made to not only increase the operation of magnetic disc suspending 8 without waiting for horizontal feed vehicle 1
Efficiency, moreover it is possible to reduce the quantity of magnetic disc suspending 8.
Stationary hopper 4 in the present embodiment is side opening structure.Steel scrap 7 is in gravity after the side door 41 of stationary hopper 4 is opened
In the lower automatic landing of effect to horizontal feed vehicle 1, discharging, charging action are easily realized.
Horizontal feed vehicle 1 in the present embodiment is gravity self-tipping type structure, and compartment bottom surface is inclined-plane, and side door is put for arc
Arm configuration；The angle of compartment bottom surface and top levels is 30~40 degree.By reasonable setting structure, the stabilization of car body is improved
Property and reliability, and can easily realize discharging, charging action.
As being further improved for said program, the stationary hopper 4 is with being equipped with weighing sensing on horizontal feed vehicle 1
Device, can the steel scrap weight that is added thereto of Real-time Feedback.
The railway line 21 of 2 inside of horizontal rail is aerial in the present embodiment, and the railway line 22 in outside is with being preferably placed in stock ground
Face.It can avoid the moving line of ramp skip car 33 and set up overhead operating expenses and difficulty.
The workflow of the system is：For magnetic disc suspending 8 continuously to 4 dispensing of stationary hopper, steel scrap weight reaches setting
After value, horizontal feed vehicle 1 runs to 4 lower section of stationary hopper, opens stationary hopper side door 41, steel scrap 7 unloads under gravity
It drops into horizontal feed vehicle 1；Horizontal feed vehicle 1 after charging runs to 3 top of ramp skip car, and opening arc swing arm will be useless
Steel is automatically added in ramp skip car 3；Horizontal feed vehicle 1 turns away from discharge pit, and ramp skip car 3 runs to electric arc furnaces 5, and
It feeds to it, is then back to stock ground.Two horizontal vehicles 1 work alternatively, and meet multispan stock ground auto feed demand.
The feed way of horizontal feed vehicle 1 in the system is flexible and changeable, can also fill 2 buckets or the above fixed material of 2 buckets every time
Steel scrap in bucket 4, such 4 volume of stationary hopper just become original 1/2 or less, stationary hopper 4 and magnetic disc suspending 8 can also be used
The feed way being combined.
The mode that the system can utilize stationary hopper 4 and horizontal feed vehicle 1 to coordinate realizes automatic charging of the steel scrap in stock ground,
Horizontal feed vehicle 1 eliminates current steel scrap transfer operation directly through the multiple across of stock ground 9.Match somebody with somebody on double strip transmission line roads
The efficiency for improving entire stock ground auto feed is put, while also enhances the reliability of system.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
