Embodiment
Understand for technical characteristics, purpose and effect to the utility model have more clearly, contrast the embodiment of description of drawings the utility model at present.
Fig. 2 is the cross-sectional schematic of sintering circular-cooler, the motion chassis side lower sealing device of expression the utility model; Fig. 3 is the cross-sectional schematic along B B line among Fig. 2; Fig. 4 schematically shows the structure of starting point guide plate.
Like Fig. 2, shown in 3; The motion chassis side lower sealing device that the utility model proposes comprises: the guide plate 1 that is fixed on chassis wheel track 8 inboards; These guide plate 1 one ends are fixedly connected with chassis wheel track 8; As welding fixingly, the other end extends to car body side plate 5 directions of said motion chassis 13, forms flange in the inboard of chassis wheel track 8.Be arranged on said car body side plate 5 and be fixedly connected with moving horizontally sealing plate 2, the end and the car body side plate 5 that promptly move horizontally sealing plate 2 fix, and the other end extends to said wheel track 8 directions.Up-down sealing plate 3 is fixedly connected with lower shoe 4 on the wheel axial region 7 that is arranged on said chassis, and an end and the lower shoe 4 of the sealing plate 3 that promptly goes up and down fix, and the other end extends to said wheel track 8 directions, and can move up and down along said wheel track 8 with wheel 17.The said sealing plate 2 that moves horizontally all extends to said guide plate 1 with up-down sealing plate 3, and is positioned at the bottom of said guide plate 1.
In an optimized technical scheme, the said sealing plate 2 that moves horizontally is provided with, and can overlaps each other at interval with up-down sealing plate 3.
Further, move up and down along chassis wheel track 8 with wheel for the ease of said up-down sealing plate 3, this up-down sealing plate 3 is arranged on the said bottom that moves horizontally sealing plate 2.
In a feasible embodiment, all be fixed with said guide plate 1 in the inboard horizontal segment scope of said wheel track 8, promptly the inboard level at chassis wheel track 8 convexes with a ring guide plate, in the zone that is provided with said guide plate 1, is provided with the heat recovery district.
In order to move horizontally the bottom that sealing plate 2 or up-down sealing plate 3 imports said guide plate 1 with said, as shown in Figure 4, the front end of preferred guide plate 1 is upturned and forms arc and import end 14.
In addition, the said sealing plate 2 that moves horizontally is processed by pressure high-temperature flexible material with up-down sealing plate 3.For example, said sealing plate 2 and the up-down sealing plate 3 of moving horizontally processed by high-temperature resistant rubber.
1 of said guide plate can be processed by steel plate.
The working principle of the motion chassis downside seal arrangement that the utility model proposes is: saidly move horizontally car body side plate 5 bottoms that sealing plate 2 is installed in the motion chassis; Car body side plate 5 with chassis is done the horizontal circle revolution; Said lifting sealing plate 3 is installed on the lower shoe 4 of wheel axial region 7 of chassis; Both can do the horizontal circle revolution, also can move up and down along track at discharge zone with the lower shoe of the wheel axial region 7 of motion chassis 4 with the lower shoe 4 of the wheel axial region 7 of motion chassis.Wherein, Up-down sealing plate 3 constitutes overlap joint with adjacent moving horizontally and is connected between the sealing plate 2; And up-down sealing plate 3 is positioned at the bottom that moves horizontally sealing plate 2; Thereby under chassis wheel track 8 moves up and down, can not receive the influence that moves horizontally sealing plate 2 with wheel at up-down sealing plate 3, with moving horizontally sealing plate 2 the auxiliary seal effect played in the side clearance 15 between chassis and the wheel track 8 when up-down sealing plate 3 rises to horizontal position.
Particularly, owing to motive sealing 9 in the existing structure, static seal 10 are highly susceptible to wearing and tearing in using process, can't play good seal action to gap 15; In the actual production; It is serious to leak out, and adopts the structure of the utility model, through said guide plate 1 being fixed on chassis wheel track 8 inboards; Car body side plate 5 directions to the motion chassis are extended; Move horizontally sealing plate 2 and up-down sealing plate 3 and all can extend to the bottom of guide plate 1, promptly be positioned at the bottom of said guide plate with guide plate 1 overlapping areas, thus said guide plate 1, move horizontally between sealing plate 2 and the up-down sealing plate 3 to chassis and fixedly the side clearance between the bellows 6 15 played the auxiliary seal effect; Form fixedly bellows 6 inner spaces 11 and space outerpace 12, the positive pressure gas that effectively reduces inner space 11 flows and drains to space outerpace 12.
In the movement process of chassis,, can the starting point of guide plate 1 be processed the water conservancy diversion form, the arc that formation as shown in Figure 4 is upturned for the ease of play moving horizontally sealing plate 2 and successfully being imported into guide plate 1 below of motion with one of which with up-down sealing plate 3.
The seal arrangement of the utility model is positioned at the chassis side-lower; Do not change the original sealing configuration motive sealing of central cooler 9, static seal 10; Can effectively reduce air leak rate of air curtain, and the guide plate 1 of the utility model, move horizontally the inboard that sealing plate 2, up-down sealing plate are arranged on wheel track 8, nearer apart from operating table 16; Its sealing state is intuitively visible, after the sealing surface loss, can realize on-line replacing.
The above is merely the schematic embodiment of the utility model, is not in order to limit the scope of the utility model.Any those skilled in the art, equivalent variations of under the prerequisite of design that does not break away from the utility model and principle, having done and modification all should belong to the scope that the utility model is protected.
