The replacing device is characterized by simple structure, easy operation and fast replacing speed, and can fast move the ram to the side from the center of the preventer, thereby reducing operation time, reducing labor intensity, facilitating replacement, maintenance and the like of the ram, and being applicable to drilling blowout preventers and oil testing blowout preventers.

Description

A kind of device that is used to change the ram preventer flashboard

Technical field

The utility model belongs to petroleum gas drilling and extracting equipment technical field, relates to a kind of device that is used to change the ram preventer flashboard.

Background technology

The well drilling blowout prevention device is in the drilling process, is installed in the visual plant that prevents on the drilling channel that gas blowout accident from taking place.Ram preventer is made up of housing, side door, flashboard assembly and oil cylinder etc., flashboard assembly mounted in pairs is in the flashboard chamber of preventer main casing both sides, and the oil cylinder by both sides promotes respectively, to the well head central motion, realize merging or separating, play the effect of closing or opening well head.Because the needs that drilling technology and preventer are safeguarded must regularly be opened the side door of ram preventer housing both sides and change flashboard.The flat side door formula ram preventer of opening is owing to the restriction of design feature, after side door is opened, flashboard directly hangs out relatively difficulty from the top, especially install in double disc well drilling blowout prevention device lower chamber and when taking out flashboard, because the stopping of fluid cylinder, change flashboard difficulty more, not easy to operate.

Summary of the invention

The purpose of this utility model provides a kind of device that is used to change the ram preventer flashboard, can change the flashboard of ram preventer easily, has solved problems of the prior art.

The technical scheme that the utility model adopted is, comprise the bracket I I, bracket I and the otic placode that connect successively, bracket I I is a T shape structure, its less end face is towards bracket I, and this inwardly be processed with T-slot than small end face certainly, and bracket I is a T shape structure towards the end of bracket I I, T shape structure on the bracket I and the T-slot on the bracket I I constitute sliding pair, bracket I I is provided with fastening devices, and bracket I is connected with otic placode by pin I, and bracket I can be rotated around pin I.

Feature of the present utility model also is,

Relative position between bracket I and the otic placode is fixed by pin II.

More changing device of the present utility model adopts

The utility model has adopted the flashboard changing device more that takes out or install flashboard from the side, when addressing the above problem, has improved the speed that flashboard is changed.

Description of drawings

Fig. 1 is the more structural representation of changing device of the utility model;

Fig. 2 is the A-A sectional view of Fig. 1.

Among the figure, 1. otic placode, 2. pin I, 3. pin II, 4. bracket I, 5. fastening devices, 6. bracket I I, 7. flashboard, 8. flashboard axis, 9. side door, 10. oil cylinder, 11. ram preventers.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

The utility model is the structure of changing device more, as depicted in figs. 1 and 2, comprise the bracket I I 6, bracket I 4 and the otic placode 1 that connect successively, bracket I I 6 is a T shape structure, its less end face is towards bracket I 4, and should inwardly be processed with T-slot than small end face certainly, this T-slot connects bracket I I 6 along its length, bracket I 4 is a T shape structure towards the end of bracket I I 6, T shape structure on the bracket I 4 cooperates the formation sliding pair with the T-slot on the bracket I I 6, bracket I I 6 can slide on bracket I 4, and bracket I I 6 is provided with fastening devices 5.Bracket I 4 is connected with otic placode 1 by pin I 2, and bracket I 4 can be rotated around pin I 2, and otic placode 1 is fixed in side door 9.

By the position of pin II 3 residing diverse location fixed support I 4 with respect to otic placode 1.

Flashboard 7 on the ram preventer 11 is connected with flashboard axis 8, flashboard 7 is processed with T-slot towards an end of upper flashboard axle 8, the end that flashboard axis 8 is connected with flashboard 7 is a T shape structure, T shape structure on the flashboard axis 8 and the T-slot on the flashboard 7 constitute sliding pair, and the cylinder bar of the other end of flashboard axis 8 and oil cylinder 10 is affixed.

The termination of ram preventer upper flashboard axle 8 is changed into square by circle, then, the connecting portion of flashboard axis 8 and flashboard 7 is processed as T shape platform and T-slot structure respectively, the T-slot on the flashboard 7 is a groove.The outer shape of bracket I I 6 is a T shape platform, and is complementary with T-slot on the flashboard 7.

The coupling part of runing rest 4 and sliding support II 6 both can be designed as T shape platform and T-slot structure, also can be designed to other shape.

Bracket I I 6 is installed in this more on the changing device, or independently places as auxiliary equipment.

Bracket I 4 adopts the bearing pin location around pin I 2 postrotational location, perhaps adopts other structure fixed.

Bracket I I 6 adopts the bearing pin location in the location after moving on the bracket I 4, perhaps adopts other structural orientation.

Originally more changing device is installed on the side door of blowout preventer 9, perhaps is installed in other position of preventer, perhaps is installed on the special removable bearing, is used to change the flashboard of ram preventer.
