Breach 142, pad breach 142 complements each other to form the cunning corresponding with spacing groove 110 with hole 131, location
Groove.
As shown in Figure 4, sealing ring tensioner 200 includes: sliding platform 210, multiple tensioning sliding shoe
220, the tensioning slip frustum of a cone 230, round platform 240 fixed by sealing ring, container cover ejects post 250 and tensioning is driven
Moving portion 260, sealing ring is fixed round platform 240 and is arranged on work platforms 100 center position, and container cover ejects post
250 are arranged in sealing ring fixes on round platform 240, and container cover ejects one end of post 250 and is fixedly mounted on tensioning cunning
On the dynamic frustum of a cone 230, the tensioning slip frustum of a cone 230 and tensioning drive division 260 drive connection, multiple tensionings
Sliding shoe 220 is distributed around the tensioning slip frustum of a cone 230 circular array.
Further, sliding platform 210 center offers slip centre bore 211, and tensioning sliding shoe 220 slides
Being located on sliding platform 210, the tensioning slip frustum of a cone 230 slides along slip centre bore 211 axis direction.
Tensioning sliding shoe 220 is provided with sealing ring tension pole 221, and one end of sealing ring tension pole 221 is with spacing
Groove 110 coordinates the plane installed and be higher than work platforms 100.Tensioning sliding shoe 220 is provided with slip tiltedly
Face 222, sliding bevel 222 coordinates with the contact of incline plane of the tensioning slip frustum of a cone 230.
Further as shown in Figure 5, the tensioning slip frustum of a cone 230 includes: first cylinder table the 231, second circle
Pylon 232 and be located at the frustum of a cone 233 between the first cylinder table 231 and the second cylinder table 232, sliding bevel
222 coordinate with the contact of incline plane of the frustum of a cone 233.
Referring to Fig. 4, sealing ring is fixed round platform 240 and is included that first fixes round platform 241 and the second fixing circle
Platform 242, second fixes round platform 242 coordinates installation with work platforms 100.Second diameter fixing round platform 242
Less than the first diameter fixing round platform 241.
In an embodiment of the present invention, tensioning drive division 260 is that tensioning drives cylinder, spacing groove 110 with
Tensioning sliding shoe 220 is provided with 10.
In conjunction with Fig. 2-Fig. 4, it is to be noted that, when carrying out sealing ring installation, sealing ring is arranged on sealing ring solid
Determine on round platform 240, owing to one end of sealing ring tension pole 221 coordinates installation with spacing groove 110 and is higher than
The plane of work platforms 100, sealing ring is just inserted on multiple sealing ring tension poles 221 of shape ringwise,
Drive the tensioning slip frustum of a cone 230 to move downward now by tensioning drive division 260, thus drive and connect with it
Touch the tensioning sliding shoe 220 coordinated to slide in and out, make the sealing ring on sealing ring tension pole 221 the most uniform
Open, and keep constant expansion state.
After sealing ring expansion, it would be desirable to the container cover installing sealing ring is put on work platforms 100, by holding
Device lid spacer 130 is fixed on the positioning, and completes fixing rear lowering or hoisting gear 300 and drives sealing ring tensioner
200 decline, so that sealing ring departs from sealing ring tension pole 221 and is inserted in container cover, by close after completing
Sealing ring is compressed by seal hold down gag 400, and last lowering or hoisting gear 300 resets, thus drives container
Caping goes out post 250 and ejects container cover.
The present invention limits the glide direction of tensioning sliding shoe 220 by arranging spacing groove 110, makes each
Tight sliding shoe 220 can guarantee that the consistent of glide direction, enables sealing ring the most all to open.
Coordinate by arranging first cylinder table the 231, second cylinder table 232 and contacting with each other with sliding bevel 222
The frustum of a cone 233, make uniformly promote each tensioning sliding shoe during the tensioning slip frustum of a cone 230 slide downward
220 move, thus ensure that the sealing ring on sealing ring tension pole 221 can uniformly open, thus ensure to install all
Even, improve sealing property.
When the tensioning slip frustum of a cone 230 slips down at certain position, sliding bevel 222 can be with the first cylinder
The cylindrical plane of platform 231 contacts, so that tensioning sliding shoe 220 stops sliding.By arranging the first circle
Pylon 231, makes each tensioning sliding shoe 220 slide displacement all keep consistent, and by the first cylinder table 231
Cylindrical plane can guarantee that tensioning sliding shoe 220 will not decline due to effect of inertia or mobile further, thus
Tensioning sliding shoe 220 is made can stably to carry out strained movements.
The present invention is provided with the container cover spacer 130 and container cover pad 140 matched, due to sealing ring
There is certain thickness, solid with position that hole 131 matches second by container cover spacer 130 is inserted in
Determining at round platform 242, the position that can fix container cover spacer 130 makes it not be moved.By arranging appearance
Device lid spacer 130 makes sealing ring be in the installation site of correspondence, such that it is able to fitted seal circle hold down gag
400 pairs of sealing rings are fixed.
Referring to Fig. 1, lowering or hoisting gear 300 includes bracing frame 310 and lifting drive division 320, bracing frame
310 bottoms being fixedly mounted on work platforms 100, sliding platform 210 slides and is located on bracing frame 310, rises
Fall drive division 320 and sliding platform 210 drive connection.
In an embodiment of the present invention, lifting drive division 320 is lift cylinder.
Being noted that after container cover is inserted in container cover spacer 130, lifting drive division 320 drives sliding
Moving platform 210 moves downward band dynamic seal ring tension pole 221 and moves downward, and makes sealing ring depart from and is contracted to
In container cover.
Shown in Fig. 3 Yu Fig. 6, sealing ring hold down gag 400 includes that multiple compression drives motor 410, many
Individual compression drives motor 410 to arrange around shim through bore 141 circular array.
Compress and drive motor 410 drive connection to have sealing ring compact heap 420.Sealing ring compact heap 420 includes
One compact heap 421 and the second compact heap 422, the first compact heap 421 identical with the second compact heap 422 structure and
It is symmetrically set, between the first compact heap 421 and the second compact heap 422, is provided with gap.
The edge of the first compact heap 421 is arc-shaped, and the center of circle of circular arc is consistent with the center of circle of centre bore 120,
And first compact heap 421 arc-shaped edge just with sealing ring expand after edge match, first compress
The center position at block 421 edge offers the groove 421a matched with sealing ring tension pole 221.
It is noted that between the first compact heap 421 and the second compact heap 422 and is provided with gap, by compressing
Drive motor 410 to drive to move, thus sealing ring is fixed.First compact heap 421 with
It is provided with gap between second compact heap 422, thus sealing ring is fixed, by the edge of arc-shaped
Sealing ring is compressed, so that sealing ring firmly coordinates with container cover.
Compared with prior art, the following is advantages of the present invention:
The container cover sealing ring of the present invention is installed equipment 10 and is realized automatization's installation sealing ring, thus instead of people
The mode that work produces, substantially increases production efficiency and reduces production cost.By arranging sealing ring tensioning
Device 200 and sealing ring hold down gag 400, enable sealing ring uniform expansion and be inserted in container cover, thus
Substantially increase the sealing of container cover, improve the quality of production from this.
The above embodiment only have expressed the several embodiments of the present invention, and it describes more concrete and detailed
Carefully, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this
For the those of ordinary skill in field, without departing from the inventive concept of the premise, it is also possible to make some changes
Shape and improvement, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with
Claims are as the criterion.
