Embodiment 1

[0027] Such as figure 1 , figure 2 and image 3 As shown, the present invention discloses a special hoisting tool for blowout preventer, including a flange 1 connected with the blowout preventer and a lifting plate 2 connected with lifting equipment;

[0028] The flange 1 is compatible with the upper flange port of the blowout preventer. There are several threaded holes 3 evenly distributed on the flange 1 to connect and fix the upper flange port of the blowout preventer. Through the threaded holes 3, the flange 1 It is fixedly connected with the upper flange port of the blowout preventer;

[0029] The lifting plate 2 is an isosceles trapezoidal ear plate whose upper bottom length is greater than that of the lower bottom. Both ends are provided with a circular lifting hole 4, and the lifting plate 2 is fixedly connected with the lifting equipment through the circular lifting hole 4 as a lifting point.

[0030] In this example,

[0031] one. In order to improve the stab...

Abstract

The invention relates to a special hoisting tool for a blowout preventer, which includes a flange connected to the blowout preventer and a lifting plate connected to a lifting device; Evenly distributed on the blue plate are a number of connecting holes fixedly connected with the upper flange of the blowout preventer, through which the flange is fixedly connected with the upper flange of the blowout preventer; the lifting plate is an upper bottom with a length greater than An isosceles trapezoidal ear plate with the length of the lower bottom, the lower bottom surface of the lifting plate is welded on the upper end surface of the flange, and the two ends protrude from the edge of the flange, and there are lifting holes at both ends of the lifting plate, through which the lifting plate The holes make the lifting plate fixedly connected with the lifting equipment. The invention has the advantages of simple structure, convenient manufacture, low cost, and strong locking and lifting capabilities.

Description

technical field [0001] The invention relates to the technical fields of marine engineering and shipbuilding, in particular to a special hoisting tool for a blowout preventer. Background technique [0002] The blowout preventer is the core equipment in the well control equipment, which is used to control the wellhead pressure, realize near-balanced or under-balanced pressure drilling, and improve the drilling speed and quality. In the case of emergency situations such as seed flow, well kick, and blowout during drilling operations, the operator should immediately issue a well shut-in command, and the blowout preventer should quickly activate the well shut-in. At this time, once the blowout preventer fails, it will lead to vicious accidents such as blowout, resulting in equipment damage and casualties. Therefore, the blowout preventer is one of the key links to ensure the smooth progress of drilling operations and personal safety. [0003] like Figure 4 As shown, the blowou...
