The oven roof sealing device for hanging heat-treatment furnace that the utility model provides; power and fire door synchronous operation that fire door rotating shaft provides can be used; the edge on sealing furnace roof top is cracked; and ensure at high temperature can normally work, play and stop furnace heat loose, protection furnace binding, energy-saving and cost-reducing, the effect that ensures Ways of Heat Treatment Product Quality outward.
Accompanying drawing explanation
Fig. 1 is that this is for hanging the oven roof sealing device front view of heat-treatment furnace.
Fig. 2 is the top view of Fig. 1.
To be this to crack capping cross-sectional view for furnace roof of the oven roof sealing device hanging heat-treatment furnace Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is illustrated.
As shown in Figure 1, Figure 2, this has for the oven roof sealing device hanging heat-treatment furnace the vertical pivot 1 be vertically connected with fire door tumbler shaft, the lower end of this vertical pivot 1 is connected with fire door tumbler shaft is concentric by flange, the top of this vertical pivot 1 is supported by the vertical pivot bearing block 2 be fixed on body of heater, vertical pivot bearing block 2 adopts spherical bearing block, is bolted on body of heater side surface upper part.The upper end of vertical pivot 1 to be linked and packed large bevel gear 3 by key.Furnace roof is provided with the first transverse axis 5, this first transverse axis 5 is parallel with furnace top surface, supported by a pair first transverse axis bearing blocks 13 be fixed on above furnace roof, the prolongation axis of this first transverse axis 5 and the prolongation axis vertical take-off of vertical pivot 1, the first transverse axis bearing block 13 adopts spherical bearing block.Be linked and packed by key in the end of the first transverse axis 5 cone pinion 4 of engagement orthogonal with large bevel gear 3.The inner side that furnace roof is positioned at the first transverse axis 5 is provided with second transverse axis 9 parallel with this first transverse axis 5, and this second transverse axis 9 is supported by a pair second transverse axis bearing blocks 8 be arranged on above described furnace roof.Second transverse axis bearing block 8 is monolithic construction, and inside is provided with self-lubricating bearing, and the selection of this second transverse axis bearing block 8 is to meet hot environment job requirement.First transverse axis 5 welds the first swing arm 6, and this first swing arm 6 is mutually vertical with the first transverse axis 5, and the second transverse axis 9 welds the second swing arm 10, and this second swing arm 10 is vertical with the second transverse axis 9.First swing arm 6 is identical with the second swing arm 10 size to be positioned at same plane and to be arranged in parallel.The front end of the first swing arm 6 and the rear end of connecting rod 7 are hinged by bearing pin, and the front end of connecting rod 7 and the front end of the second swing arm 10 are hinged by bearing pin.Pivoted arm 11 parallel with the second swing arm 10 and at angle is welded at the middle part of the second transverse axis 9, and the pivoted arm 11 of accompanying drawing embodiment is made up of pair of parallel plate.The front end soldering furnace of pivoted arm 11 backs down and seams lid 12.
This gear ratio for the large bevel gear 3 and cone pinion 4 that hang the oven roof sealing device of heat-treatment furnace, between 1.2 ~ 1.5, to make the crack corner of capping 12 of furnace roof be greater than the corner of fire door, avoids furnace roof capping 12 of cracking to produce interference to the suspender passed through.The large bevel gear 3 of the present embodiment is 21 teeth, and cone pinion 4 is 15 teeth, and large bevel gear 3 is 1.4 with the gear ratio of cone pinion 4.
As Fig. 3, this has for the capping 12 of cracking of furnace roof of the oven roof sealing device hanging heat-treatment furnace the rectangular box 14 that Open Side Down, and this rectangular box 14 is welded by heat resisting steel or heat resisting cast steel casting.Fill heat insulation felt 15 in rectangular box 14 inside, the lower surface of insulation quilt 15 protrudes from the lower surface of rectangular box 14.Rectangular box 14 is distributed with the blind rivet 16 laterally running through insulation quilt 15, for ensure furnace roof crack capping 12 move time insulation quilt 15 can not come off.
This is arranged on after on body of heater for the oven roof sealing device hanging heat-treatment furnace, when door opened or close time, fire door tumbler shaft rotarily drives the vertical pivot 1 be attached thereto and rotates, the large bevel gear 3 at vertical pivot 1 top rotates with same angle rotation direction, and drive cone pinion 4 to reversely rotate, the anglec of rotation is 1.4 times of large bevel gear 3, and cone pinion 4 drives the first transverse axis 5 to do the rotation of identical rotation direction and angle.First swing arm 6, connecting rod 7, second swing arm 10 form quadric chain, because of the first swing arm 6 and the second swing arm 10 measure-alike, therefore the first transverse axis 5 be connected with the first swing arm 6 and the second transverse axis 9 of being connected with the second swing arm 10 have identical rotation direction and angle.Furnace roof crack capping 12 by pivoted arm 11 with the second transverse axis 9 for axle rotate, and the rotation of respective direction and corner is done in furnace roof capping 12 of cracking when the second transverse axis 9 rotates, realize with door opened, close synchronous furnace roof crack capping unlatching and close, the sealing ensureing to realize while suspender and workpiece pass in and out burner hearth furnace roof edge and crack.
