Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and more specifically, to a hoisting fixture. Background Technology

[0002] Drilling casing head is the core wellhead equipment in oil and gas drilling engineering. As an important hub connecting the underground casing string and the surface blowout preventer system, it plays a key role in ensuring the integrity of the wellbore, controlling downhole pressure, and supporting multiple layers of casing.

[0003] During the installation of the casing head, it needs to be lifted by a pneumatic winch from the drilling equipment and transported to the wellhead for connection with the casing. However, there are no specialized lifting tools available. The conventional method is to insert bolts into the diagonal flange holes, attach one end of a sling to the bolt, and connect the other end to the pneumatic winch hook for lifting, or simply tie a long sling directly to the casing head flange. Because the casing head has a side outlet gate, the weight at both ends is not perfectly symmetrical, making it prone to tilting and slippage during lifting, posing a significant safety hazard.

[0004] In conclusion, improving the safety of drilling casing head hoisting is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a lifting fixture that can adjust the lifting position according to the weight difference between the two sides of the drilling casing head during lifting, so that it is not easy to tilt or slip during the lifting process, thus greatly improving the safety of lifting.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lifting fixture for lifting drilling casing heads, comprising:

[0008] The body has a plurality of connection holes for connecting with the drilling casing head and at least two connectors for connecting with hoisting equipment, wherein the spacing between the at least two connectors is adjustable.

[0009] Furthermore, the connector includes a hoisting part and a connecting part. The hoisting part is a ring-shaped structure and is connected to the hoisting equipment via a rope. The connecting part is used to connect the connector to the main body.

[0010] Furthermore, in this invention, the connecting portion is slidably mounted on the body.

[0011] Furthermore, the main body is provided with a sliding groove, and the connecting part is slidably installed in the sliding groove.

[0012] Furthermore, in this invention, the cross-section of the connecting part is T-shaped, and the groove has a structure similar in shape to the connecting part.

[0013] Furthermore, this utility model also includes:

[0014] A positioning element is used to fix the position of the connector and the body.

[0015] Furthermore, the main body is provided with a plurality of first limiting holes that communicate with the slide groove, and the plurality of first limiting holes are evenly distributed along the length direction of the slide groove. The connector is provided with at least one second limiting hole. When the positioning member is simultaneously inserted into the first limiting hole and the second limiting hole, the position of the connector and the main body is fixed.

[0016] Furthermore, the positioning element is a rod-shaped structure, with a limiting block at one end and a detachable limiting element installed at the other end.

[0017] Furthermore, in this utility model, the limiting member is a nut, and the end of the positioning member away from the limiting block is provided with a thread.

[0018] Furthermore, the main body of this invention is provided with reinforcing ribs.

[0019] The hoisting fixture provided by this utility model has several connecting holes on its main body, which penetrate the main body and are bolted to the flange of the drilling casing head. This achieves a fixed connection between the main body and the drilling casing head. During use, the installation positions of the main body and the drilling casing head can be determined according to the position of the hoisting equipment and the drilling casing head. The installation positions of the main body and the drilling casing head can be adjusted in real time, which is beneficial for the installation of the drilling casing head. The main body also has at least two connecting parts for connecting with the hoisting equipment. The spacing between the at least two connecting parts is adjustable, meaning that multiple connecting parts are installed on the main body and connected to the hoisting equipment via ropes. This allows the hoisting equipment to move the drilling casing head. By adjusting the relative position of the connecting parts and the main body, the hoisting center of gravity of the drilling casing head can be controlled, preventing tilting or slippage, improving the installation performance, and facilitating center of gravity adjustment, thus greatly improving the efficiency of drilling casing head hoisting.
