Abstract
The utility model relates to a buckle tube of a rotating blowout preventer, pertaining to the manufacturing technical field of the rotating blowout preventer. The utility model changes the connecting mode of bolts, consisting of a buckle tube and a central tube buckle, wherein, the buckle tube connects the central tube with a rotary sleeve. The utility model adopts the mode of buckle so as to realize the consistency of the connecting torque of the central tube and the rotary sleeve, saves a large amount of time and lowers labor intensity, so the connection is more reliable.
Description
A kind of drilling rotary blowout preventer snap-in cartridge is used for being connected of drilling rotary blowout preventer central tube and turning set, belongs to the manufacturing technology field of drilling rotary blowout preventer.
In the prior art, still there is not homemade similar drilling rotary blowout preventer, at the drilling rotary blowout preventer of usefulness mainly from external introduction, patent No. is 992416493 Chinese utility model patent, a kind of drilling rotary blowout preventer is disclosed, no matter but be external, still the disclosed drilling rotary blowout preventer of Chinese patent, its central tube all is to adopt bolt to connect with being connected of turning set, the shortcoming of existing connected mode is: since need connecting bolt quantity more, and specification is also bigger, during operation, the operating point is overhead higher, therefore, working strength is bigger and dangerous, and the screw-down torque of every bolt also is difficult to consistent.
The purpose of this utility model is to design a kind of connecting bolt that do not need, and adopts the buckle mode to connect the drilling rotary blowout preventer snap-in cartridge of central tube and turning set.
The utility model is achieved in that the utility model is made of snap-in cartridge and central tube buckle, snap-in cartridge is provided with buckle, buckle slot and dowel hole, the central tube buckle is arranged on the top of central tube, also have with snap-in cartridge on the buckle and corresponding buckle of buckle slot and the buckle slot that are provided with, during use, snap-in cartridge is inserted in turning set, buckle on the snap-in cartridge is fallen in the buckle slot that is arranged on central tube top, then snap-in cartridge is rotated 90 degree, alignment pin is inserted to finish in the dowel hole being connected of central tube and turning set again.
The utility model has the advantages that: owing to adopted the mode of buckle, therefore, in use can accomplish the uniformity of screw-down torque, also save a large amount of time, alleviate labour intensity, and connect also more reliable.
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a sectional arrangement drawing of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing: the utility model is made of snap-in cartridge 1 and central tube buckle 5, snap-in cartridge 1 is provided with buckle 4, buckle slot 6 and dowel hole 8, the central tube buckle is arranged on the top of central tube 3, be provided with central tube buckle 5 and central tube buckle slot, during use, snap-in cartridge 1 is inserted in turning set 2, buckle on the snap-in cartridge 14 is fallen in the central tube buckle slot that is arranged on central tube 3 tops, then snap-in cartridge 1 is rotated 90 degree, again alignment pin 7 is inserted and to finish in the dowel holes 8 being connected of central tube 3 and turning set 2, reversed in order during dismounting can be finished dismounting.
