The specific embodiment
Extremely shown in Figure 5 like Fig. 1; The specific embodiment of the utility model is a kind of pneumatic rotary self-locking ash gate of extractor; Comprise shell flange 1, door flange 2 and be arranged on shell flange 1 and door flange 2 mating surfaces between hypotenuse sealing ring 3; Wherein said door flange 2 is driven by master cylinder 4 and cooperates with shell flange 1, and the outer rim of said shell flange 1 is set with rotating self-locking ring 5, and said door flange 2 all sides radially outward are set with at least two sliding axles 20 that are set with the cover 21 that rolls; In the present embodiment; Be welded with ten sliding axles 20 and be distributed on a flange 2 all sides on the said door flange, offer on the said self-locking ring 5 and said sliding axle 20 corresponding axially directed grooves 50, these axially directed groove 50 tail ends offer the tight lock skewed slot 51 that be communicated with and opposite with said self-locking ring 5 direction of rotation with said axially directed groove 50; Said master cylinder 4 driving gate flanges 2; Make sliding axle 20 through the axially directed groove 50 on the self-locking ring 5, and further the rotation through self-locking ring 5 makes sliding axle 20 slip into tight lock skewed slot 51, and then reach pressing and self-locking state of a flange 2 and shell flange 1.
Obviously can know in conjunction with Fig. 1, Fig. 3 and Fig. 5; Fit system between self-locking ring 5 and the shell flange 1 is following: said self-locking ring 5 all sides lean on the position of top to offer at least two high accuracy axis holes 52, in the present embodiment, are uniformly distributed with on the self-locking ring 5 and offer 20 high accuracy axis holes; Be equiped with limit shaft 6 on the said high accuracy axis hole 52; One end suit of this limit shaft 6 protrusion high accuracy axis holes 52 is by slip cap 60, and chute 10 bottom surfaces of offering on this slip cap 60 and shell flange 1 upper surface form and are slidingly matched and form radially spacingly, vertically offer screwed hole 53 with said high accuracy axis hole 52 corresponding positions on said self-locking ring 5 upper surfaces and this screwed hole 53 is vertical with said high accuracy axis hole 52 formation; Be equiped with holding screw 7 on the said screwed hole 53; Said limit shaft 6 forms fixed installation through the pressuring action and the said self-locking ring 5 of said holding screw 7, in the present embodiment, owing to be set with rotating self-locking ring 5 in shell flange 1 outer rim; Offer again on this self-locking ring 5 and sliding axle 20 corresponding axially directed grooves 50 and the tight lock skewed slot 51 that with this axially directed groove 50 tail ends be communicated with of door on the flange 2; When master cylinder 4 driving gate flanges 2 are closed, make that the sliding axle 20 on the door flange 2 gets into axially directed groove 50, then through rotating self-locking ring 5; Make sliding axle 20 get into tight lock skewed slot 51, thereby realize self-locking.
From Fig. 3, also can know; For improving the rigidity intensity of self-locking ring 5; Said self-locking ring 5 all sides be installed with stiffening ring 8 by the centre position; Arbitrary shapes such as that this stiffening ring 8 is preferably is square, rectangle, cylindrical or π shape, obviously, what the present embodiment that in Fig. 3, shows adopted is square stiffening ring 8.
Can know that in conjunction with Fig. 1 and Fig. 2 form the α angle between said tight lock skewed slot 51 and the said axially directed groove 50, this α angle is preferably 90 °-100 °; Different-thickness according to the hypotenuse sealing ring; This α angle can further be preferably 94 °, 95 ° or 96 °; In the present embodiment, said α angle is 94 °, through putting into practice repeated validation; No matter 94 ° α angle is all proper on the tensile property of self-locking ring 5 or at the tight lock seal aspect of opposite house flange 2 and shell flange 1.
Can know among Fig. 2 that self-locking ring 5 both sides of present embodiment respectively are provided with a countercylinder 9, and this self-locking ring 5 drives and realizes to rotate through said countercylinder 9.
The concrete self-locking process of the ash gate among the utility model embodiment is following:
After master cylinder 4 driving gate flanges 2 are closed; Sliding axle 20 is in the tail end of the axially directed groove 50 on the self-locking ring 5; Produce rigid collision for avoiding sliding axle 20 occurring with axially directed groove 50, thereby cause the phenomenons such as the lost of life of self-locking ring 5, the outside dimension of the rolling that is designed cover 21 is less than the width of axially directed groove 50; Owing to be provided with hypotenuse sealing ring 3 between the mating surface of door flange 2 and shell flange 1; Therefore a flange 2 has certain elastic space with cooperating of shell flange 1, for tight lock skewed slot 51 has been reserved the possibility of locking, drives self-locking ring 5 rotations through countercylinder 9 and makes sliding axle 20 get into the tight skewed slot 51 of locking; And then the realization self-locking, effectively evaded the problem that causes ash gate to unclamp voluntarily because of the minimizing of the air pressure in the master cylinder 4.
Obviously; The utility model is not limited only to the technical scheme of the foregoing description; Such as changing axially directed groove and the tight quantity of locking the angle between the skewed slot or changing sliding axle, limit shaft; Also or change the shape etc. of stiffening ring, all be based on the improvement of associating that the spirit of the utility model is amplified out, fall among the protection domain of the utility model.
