Abstract
The utility model discloses a material stop device for a twin-screw sintering machine trolley. The material stop device for the sintering machine trolley is fixed on a sintering machine trolley body by transversely arranged at least two rows of bolts, and a transverse length L of a contact surface between the material stop device for the sintering machine trolley and the sintering machine trolley body is greater than or equal to 180mm, and is less than or equal to 240mm. Compared with the prior art, the problems of loosening and deformation of the existing material stop device for the sintering machine trolley can be solved.
Description
Technical field
The utility model relates to technical field of metallurgical machinery, especially a kind of double screw rod sintering pallet stock stop.
Technical background
The sintering pallet stock stop that uses in sintering production process at present is all to adopt single screw rod to be fixed on the sintering pallet body; Because chassis baffle plate in process of production is subject to the extruding of the material on sintering pallet for a long time, impact with the sinter cake that forms through sintering process when the batch turning, the set bolt of stock stop is loosening (or stretching) easily, cause the loosening distortion of sintering pallet stock stop, make sintering machine when running chassis stock stop very easily scrape stay-warm case, igniter or sintering machine head-tail star-wheel place, cause the equipment fault stopping time, seriously influence equipment operation rate.In addition, in sintering production process, the operating mode of continuous high temperature has also been aggravated the loosening distortion of sintering pallet stock stop and set bolt thereof.
The utility model content
The utility model provides a kind of double screw rod sintering pallet stock stop, and it can solve the problem of the loosening distortion of existing sintering pallet stock stop.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: described sintering pallet stock stop is being bolted on the sintering pallet body by at least two rows of lateral arrangement.The lateral length L of described sintering pallet stock stop and described this contact level of sintering pallet is more than or equal to 180mm, less than or equal to 240mm.
In technique scheme, scheme is more specifically: the lateral length L of described sintering pallet stock stop and described this contact level of sintering pallet is more than or equal to 180mm, less than or equal to 240mm; The locking nut that is used for fastening described bolt is the self-locking type nut.
Owing to adopting technique scheme, the utility model compared with prior art has following beneficial effect:
1, because the sintering pallet stock stop is fixed by two row's bolts, and the locking nut that is used for fastening described bolt is the self-locking type nut, therefore strengthened the fastening effect of sintering pallet stock stop, eliminate fastening vibration loosening, realized in use long-term fastening indeformable of sintering pallet stock stop.
2, due to the lateral length L of sintering pallet stock stop and this contact level of sintering pallet more than or equal to 180mm, less than or equal to 240mm, compared with prior art increased the stress surface of sintering pallet stock stop and sintering pallet paper spare, reduce the force intensity that is subjected to of stress surface, reduce stress deformation, eliminated the equipment stopping time that causes because of the loosening distortion of sintering board stock stop, significantly the lifting means operating rate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing example:
Embodiment of the present utility model comprises sintering pallet stock stop 1, sintering pallet body 2, bolt 3, locking nut 4.
Embodiment as depicted in figs. 1 and 2, sintering pallet stock stop 1 arrange bolts 3 by two of lateral arrangement to be fixed on sintering pallet body 2, and the locking nut 4 that is used for fastening described bolt 3 is the self-locking type nut.The lateral length L of described sintering pallet stock stop 1 and described sintering pallet body 2 contact-making surfaces is more than or equal to 180mm, and less than or equal to 240mm, two rows that this design has realized the sintering pallet stock stop are requisite space fixedly; Also simultaneously because sintering pallet stock stop and this contact level of sintering pallet lateral length L rise to (180mm＜=L＜=240mm), sintering pallet stock stop 1 significantly increases with sintering pallet body 2 contact-making surfaces, making in process of production, sintering pallet stock stop 1 is subjected to the power F1 that material pushes and the sintering pallet sinter cake is hit and produces, act on by sintering pallet stock stop 1 that on sintering pallet body 2, pressure significantly reduces, solve the problem of the stress that sintering pallet stock stop 1 too concentrated, reduced its stress deformation situation.
Claims (3)
