Fig. 1: according to the chassis side seal hold down gag overall schematic of the utility model enforcement;
Fig. 2: the big trundle cutaway view of chassis side seal hold down gag among Fig. 1;
Fig. 3: the upper and lower sleeve barrel structure sketch map among Fig. 1;
Wherein, Column 1, afterbody ears formula cylinder 2, connecting axle 3, guide rail 4, seal groove 5, upper bush 6, lower sleeve 7, big roller 8, trundle 9, italic 10, chassis side seal bearing 11, packing ring 12, steel pipe 13, double-screw bolt 14, nut 15, ceramic fiber blanket 16, furnace wall sealing cutter 17, chassis sealing cutter 18, slotted hole 19.
The specific embodiment:
Implementation method below in conjunction with description of drawings the utility model device.
As shown in Figure 1; The utility model discloses a kind of chassis side seal hold down gag, comprise column 1, afterbody ears formula cylinder 2, guide rail 4, seal groove 5, upper bush 6, lower sleeve 7, big roller 8, trundle 9, italic 10, chassis side seal bearing 11, packing ring 12, steel pipe 13; Column 1 is connected with the afterbody of afterbody ears formula cylinder 2, and afterbody ears formula cylinder 2 levels are unsettled horizontal, and its piston end is connected with the guide rail 4 of horizontal direction through rotatable connecting axle 3; Two trundles 9 are connected with guide rail 4 also and can on the inclined-plane of italic 10, slide up and down; Seal groove 5 along continuous straight runs settings and sleeve up and down 6 and 7 movable supporting through vertical direction; The lower surface that the big roller 8 coaxial last wheel faces that are installed in two trundles, 9 centres and big roller 8 withstand seal groove 5.For practicing thrift cost, italic 10 is installed on the chassis side seal bearing 11 with lower sleeve 7; Sleeve is provided with the big equal along continuous straight runs of trundle in groups at interval up and down.
Two trundles 9 are connected with guide rail 4, are installed in big rollers 8 in the middle of the trundle 9 and withstand seal groove 5 and move up and down, and with upper bush 6 oscilaltion in lower sleeve 7 that seal groove 5 usefulness nuts are connected, have guaranteed that seal groove 5 does vertical direction and compress or unclamp motion.Definite says, guide rail 4 is with two trundles, 9 up-down maintenance constantly levels, but its integral body is done the oblique line directions reciprocating motion along with cylinder piston is flexible, and seal groove 5 is done the vertical direction rectilinear motion.
Fig. 2 explains the structure and the up-down of big or small roller 8 and 9 from chassis side seal hold down gag roller section.The trundle 9 that the inclined-plane of italic 10 both sides is erected respectively separates with big roller 8 through the packing ring 12 of coaxial setting; Two kinds of roller inboards all use steel pipe 13 to pass; Can produce rolling like this; And very closely spaced double-screw bolt 14 and nut 15 are equipped with in steel pipe 13 the insides, couple together guide rail 4, roller 8 and 9 and move simultaneously.When the trundle 8 of both sides rolled rising on italic 10, big roller 9 rose with regard to jack-up seal groove 5, and the anti-material that fill seal groove 5 the insides---ceramic fiber blanket 16 just is pressed on furnace wall sealing cutter 17 and seals on the cutter 18 with chassis.
Fig. 3 is upper and lower cage guiding device.Upper bush 6 is connected with seal groove 5 through round nut, has slotted hole 19 on the seal groove 5 and holds upper bush 6, and upper bush 6 and seal groove 5 can be slided in the horizontal direction, avoids when going up and down and seal groove slotted hole generation dry friction, discharges certain internal force.Upper bush 6 lifting travel height are certain, and only can in lower sleeve 7, slide.
Connecting axle 3 drives guide rail 4 motions that big trundle is housed; Trundle 9 rolls on inclined-plane, italic both sides; Drive big roller 8 withstands seal groove 5 and moves up and down; Seal groove 5 leads through the sleeve up and down 6 and 7 that is coated with full glycerine lubrication, realizes that single air cylinder driven seal groove does vertical lift, thereby compresses the sealing cutter of furnace wall and chassis.
The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalence variation that the utility model claim is done, still belong to the protection domain of the utility model.
