Abstract
The utility model discloses a guiding device at the bottom of the coke educing grid of a coke-barrier car. The guiding device comprises at least two guiding wheels, a guiding wheel base and a guiding groove, wherein the guiding wheels are fixed on the guiding wheel base through bolts, the guiding wheel base is welded at the lower part of the coke educing grid, and the guiding groove is welded to the car body of the coke-barrier car. According to the utility model, the design of the guiding groove is adopted, the guiding wheels can move freely in the vertical direction of the guiding groove, and influences caused by stretching variation due to heating to the coke educing grid can be solved effectively; the moving of the guiding wheels inside the guiding groove enables the horizontal swinging of the coke educing grid to be restrained, and traveling path of the coke educing grid is enabled to be straight; the guiding wheels adopt double-wheel linear front-rear arrangement, so as to achieve that at least one guiding wheel is inside the guiding groove during the traveling of the coke educing grid, and straight coke educing grid traveling can be achieved.
Description
Technical field
The utility model belongs to the coke guide grid of coke guide bottom guiding device, and specifically burnt grid swing is led in constraint, guarantees to lead a kind of structure of burnt grid direct motion.
Background technology
In coking is produced, lead the important component part that burnt grid are coke guides, be the visual plant of coke oven production operation.During pushing coke operation, coke guide will be led burnt grid and be aimed at the heat (batch) number of wanting coke pushing, and coke guide imports coke in quenching car by leading burnt grid.Lead burnt grid and driven by connecting lever and connecting rod by two hydraulic rams, hang roller by two groups, top and move forward and backward on two slide rails, the bottom guiding mechanism moves and realizes leading the constraint of burnt grid direction of travel along guided way by guide deflection sheave.
In the prior art, guide deflection sheave be Intermediate Gray groove two ends have wheel rim circle wheel and by support with lead burnt grid bottom and be connected and fixed, guided way is a square steel and by base, is fixed on coke guide car body basis, moves to realize guide effect by guide deflection sheave along guided way while leading burnt grid traveling., although this structure can meet the need of production, there is very large defect.Lead high approximately six meters of burnt grid, expanded by heating can be elongated when pushing coke operation, due to action of gravity, leads after burnt grid are heated guide deflection sheave is pressed on guided way, the dieback phenomenon occurs, cause burnt grid to move, if run into, come out of the stove operation can cause larger accident.Distance between guide deflection sheave and guided way can't accurately be determined in addition, the expansion elongation of being led burnt grid affects, need to reserve between guide deflection sheave and guided way when certain distance makes both in cold conditions and not contact, but this kind situation can increase the amplitude of swinging while leading burnt grid traveling to be caused guide deflection sheave to ride on guide rail or occurs that guide deflection sheave strides across guided way, the dieback phenomenon occurs equally, cause burnt grid to move.
At present, the general mode that increases distance between guide deflection sheave and guided way that adopts reduces the appearance of leading burnt grid dieback phenomenon, but making, this mode leads burnt grid amplitude of fluctuation increase, cause spacing inaccurate, hang wheel and damage aggravation, lead that burnt grid failure rate is high, maintenance difficulty, somewhat expensive, in addition, have no effective treatment process.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of constraint that provides is led burnt grid and swung, reduces and lead burnt grid running resistance, the device of guaranteeing to lead burnt grid direct motion.
The utility model discloses a kind of coke guide grid of coke guide bottom guiding device, this is led burnt grid bottom guiding device and comprises: guide deflection sheave, guide deflection sheave base and guide path, wherein guide deflection sheave is bolted on the guide deflection sheave base, and the guide deflection sheave base is welded on leads burnt grid bottom; Guide path is welded on the coke guide car body, and the minimum number of guide deflection sheave is two.
Preferably, described bolt is the M20 bolt.
Preferably, the wheel rim surface of described guide deflection sheave adopts carburizing treatment, improves abrasive wear resistance and surface hardness.
Preferably, establish the aligning spot contact bearing in guide deflection sheave, reducing running resistance simultaneously can the automatic aligning centering, and its structure design can be prevented dust and maintenance easy to lubricate.
Preferably, guide deflection sheave adopts design of Sealing Structure, is used for reducing coke powder and invades, and the gland top of guide deflection sheave is provided with pouring orifice and facilitates lubrication operation.
Preferably, the bottom of guide path is provided with opening.
By adjusting the guide path position, guide deflection sheave is in the middle of guide path during installation, the effect of contraction by guide path makes leads burnt grid all the time along the guide path traveling, realizes leading the constraint of burnt grid; Simultaneously guide deflection sheave can move up and down along the guide path vertical direction, to adapt to, leads the back draft of being heated of burnt grid and changes.
The utlity model has simple in structure, easy for installation, high treating effect:
1) owing to adopting the guide path design, guide deflection sheave can move freely along the guide path vertical direction, effectively solves and leads the be heated impact of variable elongation of burnt grid;
2) can retrain and lead swinging of burnt grid to wheel movement in guide path, realize leading the straight of burnt grid traveling track; Guide deflection sheave is arranged before and after adopting the two-wheel straight line, can realize that the rarest guide deflection sheave is inner at guide path when leading burnt grid traveling, realizes leading burnt grid traveling straight;
3) guide deflection sheave is interior for double-row bearing designs, and running resistance is little and can realize the automatic aligning centering, has improved guidance capability;
4) the guide deflection sheave gland adopts Seal Design, and reduce coke powder and enter, and convenient lubricated to it at gland design pouring orifice;
5) the guide path bottom is provided with opening, reduces the accumulation of broken Jiao in guide path, has guaranteed that the guide deflection sheave traveling is smooth and easy.
