[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0034] Embodiment 1:

[0035] As Figures 1 - 8 shown, the embodiment of the present utility model provides an adaptive device for storing the movable internal blowout preventer joint for drilling and workover, which is used for temporarily placing the internal blowout preventer joint 9, and includes: a movable and height-increased base, two groups of stable clamping components, an elastic support structure, and a guide rod 15, a double rack plate 16, a first transmission gear 18, and a second transmission gear 20.

[0036] The two groups of stable clamping components are fixedly installed on the top of the movable and height-increased base, and converge from bottom to top and are symmetrically distributed, that is, in an equilateral triangle form. The two groups of stable clamping components are used to clamp and fix the internal blowout preventer joint 9. The movable and height-increased base can carry the two groups of stable clamping components for transfer, so as to realize the transfer of the internal blowout preventer joint 9 from the placement position to the use position.

[0037] Each set of stable clamping components includes: a fixed side arm frame 2, a straightening frame 3, and a meniscus 7. The bottom end of the fixed side arm frame 2 is fixedly connected to the top of the movable heightening base, the straightening frame 3 is slidably connected to the inner side of the fixed side arm frame 2, a rack portion is provided on the inner side of the straightening frame 3, and the meniscus 7 is horizontally slidably connected to the inner side of the top end of the straightening frame 3.

[0038] When the uprighting frames 3 of the two groups of stable clamping assemblies slide upward synchronously, the corresponding two menisci 7 can be gathered toward the middle and finally clamped on both sides of the inner blowout prevention joint 9.

[0039] The elastic support structure is located between the two groups of stable clamping components, and is used to support the inner blowout preventer 9, and just meets the requirement that the inner blowout preventer 9 is also located between the two groups of stable clamping components. The top of the elastic support structure is fixedly connected with a guide rod 15, and the top of the guide rod 15 has a cone portion that guides the male buckle of the inner blowout preventer 9 to be sleeved on the guide rod 15, so that when the inner blowout preventer is slowly lowered, the water eye at its bottom end can be aligned with the guide rod 15, thereby facilitating the accurate placement of the inner blowout preventer.

[0040] The bottom end of the guide rod 15 extends downward and is fixedly mounted with a double rack plate 16. The guide rod 15 and the double rack plate 16 move together with the top surface of the elastic support structure. When the top surface of the elastic support structure is subjected to force (by the gravity of the internal blowout preventer joint), they can move downward synchronously.

[0041] A first gear rack 17 and a second gear rack 19 are fixedly connected to the top of the movable heightened base and on both sides of the double rack plate 16, respectively. A first transmission gear 18 is rotatably mounted on the first gear rack 17, and the first transmission gear 18 is meshed with a first side of the double rack plate 16, and the first transmission gear 18 is also meshed with the rack portion of the adjacent straightening frame 3. A second transmission gear 20 is rotatably connected to the second gear rack 19, and the second transmission gear 20 is meshed with the second side of the double rack plate 16, and the second transmission gear 20 is also meshed with the rack portion of the adjacent straightening frame 3.

[0042] For example, during the downward movement of the double rack plate 16, the first transmission gear 18 and the second transmission gear 20 located on both sides thereof will be synchronously driven to rotate. The first transmission gear 18 will drive the centering frame 3 close to it to slide upward. At the same time, the second transmission gear 20 will also drive the centering frame 3 close to it to slide upward, so that the two centering frames 3 slide upward synchronously, thereby causing the two menisci 7 to gather towards the middle and finally being clamped on both sides of the internal blowout preventer joint 9, realizing the automatic fixation of the internal blowout preventer joint 9. That is, relying on the gravity pressing action of the internal blowout preventer joint 9, the internal blowout preventer joint 9 is fixed. In this fixing method, the internal blowout preventer joint 9 is kept in a vertical state, and by using the mobility of the movable heightening base, the drill and workover movable internal blowout preventer joint storage adaptive device and the internal blowout preventer joint 9 are transported to the use position.

[0043] In the first embodiment, the movable heightening base includes: a base body 1. A plurality of support columns 21 are fixedly connected to the bottom of the base body 1. The support columns 21 lift the base body 1. A walking wheel 22 is fixedly installed at the bottom end of each support column 21. The walking wheel 22 is used for the movement of the base body 1. A socket corresponding to the bottom end of the centering frame 3 is opened on the upper surface of the base body 1. The bottom end of the centering frame 3 is inserted downward from the socket below the base body 1. Since the base body 1 is lifted by the support columns 21, the bottom end of the centering frame 3 is prevented from hitting the ground.

[0044] In one embodiment, a flower shaft 5 is fixedly connected to the side of the meniscus 7 away from the internal blowout preventer joint 9. A flower hole 4 is opened on the side surface of the top end of the centering frame 3. One end of the flower shaft 5 penetrates through the flower hole 4, and a pin 6 is fixedly installed on the flower shaft 5 and on the back of the centering frame 3.

[0045] When the back of the meniscus 7 abuts against the side surface of the top end of the centering frame 3, a lateral force will be applied to the meniscus 7, thereby clamping the internal blowout preventer joint 9.

[0046] In the first embodiment, the elastic support structure includes: a support frame 11, an upper lining plate 10, a lower lining plate 12, and a guide post 13. The bottom end of the support frame 11 is fixedly connected to the top of the movable heightening base. The lower lining plate 12 is fixedly installed on the top of the support frame 11. A plurality of guide holes are opened on the lower lining plate 12. The bottom of the upper lining plate 10 is fixedly connected with a guide post 13. The bottom end of the guide post 13 is inserted into the guide hole. A spring 14 is sleeved outside the guide post 13 and between the upper lining plate 10 and the lower lining plate 12.

[0047] The support frame 11 raises the lower lining plate 12 upward, so that there is a space at the bottom of the lower lining plate 12 to facilitate the installation of the double rack plate 16, the first transmission gear 18, and the second transmission gear 20.

[0048] Under the cooperation of the guide column 13 and the guide hole, the upper liner 10 moves up and down relatively smoothly, and the upper liner 10 is supported by the spring 14, so that the upper liner 10 can elastically support the inner blowout prevention joint 9.

[0049] The guide rod 15 is fixedly installed with the upper lining plate 10, and the top of the guide rod 15 is located above the upper lining plate 10. The upper surface of the lower lining plate 12 is provided with a clearance hole corresponding to the bottom end of the guide rod 15. The bottom end of the guide rod 15 passes through the clearance hole of the lower lining plate 12. The guide rod 15 is slidably connected with the clearance hole. The bottom end of the guide rod 15 is located below the lower lining plate 12. The double rack plate 16 is located below the lower lining plate 12, and the top end of the double rack plate 16 is threadedly connected with the bottom end of the guide rod 15.

[0050] In the first embodiment, a non-slip pad 8 is fixedly connected to one side of the meniscus 7 close to the inner blowout prevention joint 9 to ensure the stability of the clamping.

[0051] Embodiment 2
