Description
Technical field
This utility model relates to coking industry coke oven for iron technical field, is specifically related to a kind of coke guide grid of coke guide and becomes online
Tur(e)ing unit.
Background technology
Coke guide is the corollary equipment of coke oven, typically operates on the rail of coke oven coke side, is mainly used in switching coke oven stove
Door, the incandescent coke released in coke oven chamber by pusher machine guides to coke quenching cart, and be responsible for transporting the fire door that need to keep in repair with
Firedoor frame, its effect leading burnt grid is the carbonization chamber that the leading burnt grid reach of coke pushing lets drive at blow-on door, makes to lead burnt grid and blocks coke side
Stove frame, guides the coke of 1000 degrees centigrade released by coke oven machine side pusher machine from charcoal indoor to coke quenching cart, complete
Become to lead defocused, recall in situ after leading burnt grid, once lead Jiao and complete.The coke of 1000 degrees centigrade is leading Jiao under normal circumstances
The time passed through in grid is 38 seconds, but if there is following several situations: 1) have a power failure suddenly in coke-pushing process；2) blending ratio is not
Properly cause difficult coke pushing；3) coal too much causes obstinate Jiao；4) in carbonization chamber, mixed coal coking time is inadequate, and coke is immature to be caused
Difficult coke pushing etc..Red Jiao that will cause 1000 degrees centigrade stops in leading burnt grid for a long time, fact proved, such as arnotto, Jiao exists
Stop in leading burnt grid will cause more than 10 minutes and lead burnt grid side and framework dilatancy, time serious deflection up to 100-
150, and lead burnt grid dilatancy and will result in following several equipment fault more than 50mm: 1) lead burnt grid side guide roller with leading
Extrude to track, resistance increase causes burnt grid to move；2) burnt grid alignment carbonization chamber is led for blocking the folded of stove frame
Can cause after plate deformation burnt grid do not reach stove frame, cannot opposite house；3) coke mobile resistance in leading burnt grid after burnt grid deformation is led
Power increase causes coke pushing current to raise, power consumption increases, even difficult coke pushing.
Due to the burnt time of staying red in leading burnt grid long after, it is too high to lead burnt grid ambient temperature, so, the most universal
Processing method is to allow deformation lead burnt grid naturally cool to room temperature, then according to the deformation order of severity two kinds of processing methods of employing: 1)
Leading uses external force to be pushed to return at deformation position in situ with jack when burnt grid deform serious, and this kind of processing method time is short, base
This does not affect normal production, but repairing effect is not good enough, often leaves " sequela "；2) lead when Jiao's grid deform serious and need to lead burnt grid
Dismounting carries out off-line finishing to ground, and heating shaping and removable parts skeleton shaped steel, this kind of processing method time is longer, after reparation
Can normally use, but maintenance once needs to spend 10000 yuan, disables coke guide about 48 hours, long repair time easily makes
Become the risk that coke oven stops production, very harmful.
Utility model content
The purpose of this utility model is to overcome current the above-mentioned of method existence to processing after leading burnt grid deformation to lack
Fall into, it is provided that a kind of coke guide grid of coke guide deformation in line trimming device, with ensure coke guide grid of coke guide after scaling loss dilatancy,
Can realize preventing from deforming deteriorating further and deformed target being repaired rapidly without off-line dismounting, save and led Jiao
Grid repairing cost lexpenses, has been greatly shortened the repair time, reduces coke oven production risk.
To achieve these goals, this utility model provides a kind of coke guide grid of coke guide deformation in line trimming device, institute

Detailed description of the invention
The utility model is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of coke guide grid of coke guide deformation in line trimming device, described device includes being arranged on leads burnt grid 4
Mutually isostructural two unit of both sides, described unit includes: 2 handwheels, 2,2 movable jacking blocks 3 of 1,2 leading screws, frame 5,2
Individual fixing nut 6 and 2 movable pads 7.
Preferably, the overall length of described leading screw 2 is 1200mm；One end of said two leading screw 2 inserts two respectively through frame 5
Circular hole on individual movable jacking block 3；One handwheel 1 of each welding on its other end；Laborsaving in order to reach to save when rotating handwheel 1
Purpose, it is relatively big that handwheel 1 diameter makes, and handwheel diameter 450mm is welded with 3 grip ends and facilitates hand wheel rotating on handwheel 1.
Preferably, the thread pitch of leading screw 2 and fixing nut 6 is 4.5mm, its purpose is to obtain leading screw faster and moves
Dynamic speed；Described fixing nut 6 is the workpiece of thickness 50mm screw thread M36*4.5.Install for device and need, lead Jiao at coke guide
On the former perpendicular section steel in grid both sides, transverse weld installs the 16# channel-section steel of long 1800mm, and these parts are frame 5；Two fixing nuts 6
It is welded in frame 5.
The horizontal plane of described device is positioned at leads bottom burnt grid up 2500mm place, and this position deforms the most serious for leading Jiao's grid
Place.Two fixing nuts 6 are lead burnt gate length 1/3, the most each one with the fore-and-aft distance leading burnt grid, convenient covering deformed area
All regions.Leading screw 2 with fixing nut 6 with the use of, under the fixation of fixing nut 6, by rotating change when leading screw 2 rotates
Becoming movable, leading screw 2 removes close to the one end leading burnt grid for installation activity jacking block 3, leading screw 2 and movable jacking block 3 junction
Screw thread, movable jacking block 3 makes the circular hole having ￠ 40, and the leading screw 2 removing screw thread inserts in circular hole, can realize leading screw 2 and rotate
The purpose that promotion activity jacking block 3 moves rather than rotates.Different because leading burnt grid each scaling loss deflection, make in different size
Two kinds of movable jacking blocks 3, the little movable long 300mm of jacking block 3, the big movable long 500mm of jacking block 3, and movable jacking block 3 can rotate tune
Whole desired location, when leading burnt grid deflection and being less, uses little movable jacking block 3, when leading burnt grid deflection and being bigger, uses Radix Angelicae Dahuricae (Radix Heraclei Scabridi)
Dynamic jacking block 3.
In order to reach purpose flexible, that reduce the amount of labour, raise labour efficiency, leading screw 2 and movable jacking block 3 it
Between movable pad 7 is installed, considerably reduce when leading screw 2 rotates the frictional force between movable jacking block 3, carry for operator
High work efficiency.
