Embodiment 1

[0033] Such as figure 1 , 2 , 3, 4, 5, 6, 7, and 8, a multifunctional combined wellhead well control product test device includes a frame beam 1 connected together by a left frame 10 and a right frame 11, and is characterized in that the The frame beam 1 described above is sequentially provided with a base platform 2, a suspension loading platform 3, a rotating drive platform 4, and a reciprocating platform 5 from bottom to top;

[0034] The base platform 2 is provided with a simulated shaft 13 perpendicular to the platform surface of the base platform 2;

[0035] The suspended loading platform 3 is provided with a first guide beam 301 and a loading trolley 302, and the loading trolley 302 is driven on the first guiding beam 301 by the first moving cylinder 303 provided on one side of the suspended loading platform 3 To and fro movement, the middle part of the loading trolley 302 is provided with a loading cylinder 304; the first moving cylinder 303 is fixed on the suspensio...

Embodiment 2

[0046] On the basis of Example 1, such as Figure 7 , 8 The shown reciprocating device 504 includes a guide column 505, a reciprocating cylinder 508, a rotary joint 506, and a moving beam 507. There are two guide columns 505, and the two guide columns 505 pass through the reciprocating trolley vertically. 502, and is slidingly connected with the reciprocating trolley 502, the bottoms of the two guide columns 505 are connected by a moving beam 507, the rotary joint 506 is fixed on the lower end surface of the moving beam 507, and one end of the reciprocating cylinder 508 It is connected to the bottom of the reciprocating trolley 502, and the other end is connected to the upper surface of the moving beam 507. The reciprocating cylinder 508 is connected to the hydraulic control system through the on-board pipeline 9, and the reciprocating device 504 needs to assist the third layer of rotary drive device 404, when the drill pipe is rotating and reciprocating in a small range, the...

Embodiment 3

[0048] On the basis of Example 1, such as figure 1 , 2 The first guide beam 301, the second guide beam 401, and the third guide beam 501 shown are respectively provided with a limit device 6, and the limit device 6 is located at the first moving cylinder 303 and the second moving cylinder respectively. 403, the other end of the third moving cylinder 503. The limit device 6 prevents the loading trolley 302, the loading trolley 402, and the reciprocating trolley 502 from exceeding the range to be moved during the moving process, and collides with the frame beam 1. 502 Corruption occurred.

Abstract

The invention relates to a multifunctional combined-type well mouth well-control product testing device, and the device comprises a frame beam which is formed by the connection of a left frame and a right frame. The frame beam is sequentially provided with a pedestal platform, a suspension loading platform, a rotating driving platform and a reciprocating motion platform from the bottom to the top. The pedestal platform is provided with a simulation shaft which is perpendicular to the surface of the pedestal platform. The suspension loading platform is provided with a first guide beam, a loading trolley, a first car moving cylinder, and a loading cylinder. The rotating driving platform is provided with a second guide beam, a rotating trolley, a second car moving cylinder, and a rotating driving device. The reciprocating motion platform is provided with a third guide beam, a reciprocating trolley, a third car moving cylinder, and a reciprocating motion device. The loading cylinder, the rotating driving device and the reciprocating motion device are connected with a hydraulic control system through on-board pipes. The device improves the production efficiency, reduces the manufacturing cost, eliminates a flat car, and solves a technical problem of multifunctional testing and combined testing of a blowout preventer.

Description

technical field [0001] The invention relates to a test device for wellhead well control products, in particular to a test device capable of performing multifunctional combined detection on blowout preventers. Background technique [0002] The blowout preventer is the core equipment in the drilling well control device, which is used to control the wellhead pressure and realize near-balanced or under-balanced pressure drilling. When a blowout occurs, close the blowout preventer as needed to prevent the occurrence of blowout events. [0003] The wellhead well control product test device is the necessary equipment for a comprehensive test of the blowout preventer, and is one of the key equipment to ensure the performance of the blowout preventer and even the safe production of the entire drilling system. With the popularization of underbalanced drilling technology, blowout preventer has developed from annular blowout preventer and ram blowout preventer to rotary blowout prevent...
