Rail mounted crane anti-deviation device as above, wherein, preferably: described bearing is plane needle bearing.
Rail mounted crane anti-deviation device as above, wherein, preferably: also comprise cover plate, described plate cover is located at the outside of described bearing, and is provided with opening on described cover plate, and expose from described opening on the face of cylinder of described bearing.
Rail mounted crane anti-deviation device as above, wherein, preferably: on the sidewall of described groove, be provided with mounting hole, described cover plate is fixed by bolt and described mounting hole.
Rail mounted crane anti-deviation device as above, wherein, preferably: on the sidewall of described groove, offer storage tank, described bearing is embedded in described storage tank.
Rail mounted crane anti-deviation device as above, wherein, preferably: described body is weldingly fixed on described supporting leg bottom.
Rail mounted crane anti-deviation device as above, wherein, preferably: also comprise deep floor, described deep floor is fixed on the both sides of described body.
The rail mounted crane anti-deviation device that the utility model provides is by the recess sidewall of body, bearing being set, this bearing energy grip track, and in the time that roller is advanced along track, bearing can paste track and roll.Thereby eliminate the gap between roller and track, avoided the sideslip of crane, made crane trouble-free operation.
Brief description of the drawings
The schematic diagram that the rail mounted crane anti-deviation device that Fig. 1 provides for the utility model embodiment coordinates with track;
The rail mounted crane anti-deviation device structural representation that Fig. 2 provides for the utility model embodiment;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view;
Fig. 4 is the birds-eye view of Fig. 2.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is elaborated.Wherein identical parts represent with identical Reference numeral.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric centre.
The schematic diagram that the rail mounted crane anti-deviation device that Fig. 1 provides for the utility model embodiment coordinates with track, the rail mounted crane anti-deviation device structural representation that Fig. 2 provides for the utility model embodiment, Fig. 3 be the A-A of Fig. 2 to cutaway view, the birds-eye view that Fig. 4 is Fig. 2.
The utility model embodiment provides a kind of rail mounted crane anti-deviation device, and comprising body 1 and bearing 2, body 1 is fixed on the side of crane leg bottom near roller, is preferably and is welded and fixed.On described body 1, be provided with groove 11, described groove 11 is on crane runway 3; Bearing 2 is embedded on the sidewall of described groove 11.
In above-mentioned anti-deviation device, body 1 adopts derby of the prior art to process, and processes above-mentioned groove 11 on derby, and as depicted in figs. 1 and 2, bearing 2 is embedded on the sidewall of groove 11, the roller gripper rail 3 of bearing 2.In the time that crane roller moves along track 3, bearing 2 rotates and drives whole anti-deviation device to advance along track 2.The gap between roller and track 3 has been filled up in the setting of body 1 and bearing 2, has avoided the sideslip of roller.
Preferably, above-mentioned bearing 2 is plane needle bearing.Plane needle bearing comprises the plane retainer assembly with needle roller or cylindrical roller.In the time that crane is advanced, needle roller or cylindrical roller can roll along track 3.
Preferably, anti-deviation device also comprises cover plate 4, is located at the outside of bearing 2, and is provided with opening on cover plate 4, and expose from described opening on the face of cylinder of bearing 2.As shown in Figure 3 and Figure 4, be provided with mounting hole 5 on the sidewall of groove 11, cover plate 4 is fixing by bolt and mounting hole 5.
Further, on the sidewall of groove 1, offer storage tank, bearing 2 is embedded in storage tank.Cover plate 4 is fixed type bearing 2 further, and expose from the opening of cover plate 4 on the face of cylinder of bearing 2 simultaneously, matches with track 3.
On the basis of above-described embodiment, this anti-deviation device also comprises deep floor 6, and this deep floor 6 is fixed on the both sides of body 1, is preferably and is welded and fixed.The setting of deep floor 6 can be played to whole anti-deviation device the effect of reinforcement, avoids crane in the time of hoisting heavy, and body 1 is stressed excessive and deform.
The installation process of anti-deviation device is as follows: first bearing 2 packed in storage tank, then cover plate 4 covered on bearing 2, and then by bolt is coordinated with mounting hole 5 through cover plate 4, thereby by fixing cover plate 4.
The rail mounted crane anti-deviation device that the utility model provides is by the recess sidewall of body, bearing being set, this bearing energy grip track, and in the time that roller is advanced along track, bearing can paste track and roll.Thereby eliminate the gap between roller and track, avoided the sideslip of crane, made crane trouble-free operation.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of the each embodiment technical scheme of the utility model.
