Description

Technical Field

[0001] This utility model relates to the field of offshore drilling platform installation technology, specifically a drilling platform derrick lifting lug tooling that is simple in structure, fast in installation, easy to disassemble, does not change the derrick structure, ensures the strength of the derrick structure, ensures performance safety, and saves costs. Background Technology

[0002] Currently, the functional modification of offshore drilling platforms, including the derrick, involves a significant amount of lug installation work. These lugs, connected to pulleys, alter the direction of the ropes. There are generally two methods for lug installation: the first is to weld the lugs directly to the derrick and then cut and remove them after use. This method increases installation costs and wastes the lugs due to the need for cutting and removal. The second method involves drilling holes directly into the derrick, which directly alters the structural strength and creates safety hazards. Furthermore, when the pulley system on the lugs needs to be rerouted, the lugs must be reinstalled, causing further damage to the derrick. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a drilling platform derrick lifting lug tooling that is simple in structure, fast in installation, easy to disassemble, does not change the derrick structure, ensures the strength of the derrick structure, ensures performance safety, and saves costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A drilling platform derrick lifting lug fixture, characterized in that the fixture includes a lower clamping plate, an upper pressure plate, a connecting side plate, a wing plate, a locking bolt, and a locking nut. The left and right sides of the upper pressure plate are perpendicularly connected to one end of the connecting side plate, and the outer side of the other end of the connecting side plate is perpendicularly connected to the wing plate. The wing plate is provided with a first connecting hole. The left and right sides of the lower clamping plate are provided with second connecting holes corresponding to the positions of the first connecting holes. After the n-shaped structure connecting the upper pressure plate and the connecting side plate is sleeved on the outside of the derrick I-beam, the lower clamping plate presses on the outside of the I-beam. The locking bolt passes through the second connecting hole and the first connecting hole in sequence and is connected to the locking nut. The lower end face of the lower clamping plate is connected to the lifting lug.

[0006] The distance between the lower end face of the upper pressure plate and the lower end of the connecting side plate described in this utility model is less than the height of the I-beam of the derrick.

[0007] The lower end face of the upper pressure plate of this utility model is connected to an upper rubber layer. The upper rubber layer increases the friction with the derrick I-beam, thereby increasing the clamping force between the derrick I-beam and the lifting lug fixture.

[0008] The lower clamping plate of this utility model is connected to a lower rubber layer on its upper end face. The lower rubber layer increases the friction with the derrick I-beam, thereby increasing the clamping force between the derrick I-beam and the lifting lug fixture.

[0009] The wing plate of this utility model is provided with at least two first connecting holes, and the lower clamping plate is provided with at least two corresponding second connecting holes. The wing plate and the lower clamping plate are connected by at least two locking bolts and locking nuts to ensure the stability of the connection.

[0010] This utility model, due to the above-mentioned structure, has the advantages of simple structure, fast installation speed, convenient disassembly, no change to the derrick structure, guaranteed derrick structure strength, performance safety, and cost saving. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings:

[0015] As shown in the attached figure, a drilling platform derrick lifting lug tooling is characterized in that the tooling 9 includes a lower clamping plate 1, an upper pressure plate 2, a connecting side plate 3, a wing plate 4, a locking bolt 5, and a locking nut 6. The left and right sides of the upper pressure plate 2 are respectively perpendicularly connected to one end of the connecting side plate 3, and the outer side of the other end of the connecting side plate 3 is perpendicularly connected to the wing plate 4. The wing plate 4 is provided with a first connecting hole. The left and right sides of the lower clamping plate 1 are respectively provided with a second connecting hole corresponding to the position of the first connecting hole. After the n-shaped structure of the upper pressure plate 2 and the connecting side plate 3 is sleeved on the outside of the derrick I-beam, the lower clamping plate 1 presses on the outside of the I-beam 10. The locking bolt 5 passes through the second connecting hole and the first connecting hole in sequence and is connected to the locking nut 6. The middle part of the lower end face of the lower clamping plate 1 is connected to the lifting lug 11.

[0016] Furthermore, the distance between the lower end face of the upper pressure plate 2 and the lower end of the connecting side plate 3 is less than the height of the derrick I-beam 10.

[0017] Furthermore, the lower end face of the upper pressure plate 2 is connected to the upper rubber layer 7, which increases the friction with the derrick I-beam 10, thereby increasing the clamping force between the derrick I-beam 10 and the lifting lug 11 tooling 9.

[0018] Furthermore, the upper end face of the lower clamping plate 1 is connected to the lower rubber layer 8, which increases the friction with the derrick I-beam 10, thereby increasing the clamping force between the derrick I-beam 10 and the lifting lug 11 tooling 9.

[0019] Furthermore, the wing plate 4 is provided with at least two first connecting holes, and the lower clamping plate 1 is provided with at least two corresponding second connecting holes. The wing plate 4 and the lower clamping plate 1 are connected by at least two locking bolts 5 and locking nuts 6 to ensure the stability of the connection.

[0020] In use, this utility model involves installing the fixture 9 at a specific position on the derrick according to the designed pulley installation location. After the n-shaped structure connecting the upper pressure plate 2 and the connecting side plate 3 is fitted over the outside of the derrick I-beam 10, the lower clamping plate 1 presses down on the outside of the I-beam 10. At this time, the upper rubber layer 7 on the inner side of the upper pressure plate 2 is pressed against the upper side plate of the derrick I-beam 10. Then, the lower rubber layer 8 on the lower clamping plate 1 is pressed against the lower side plate of the derrick I-beam 10. Finally, the fixture is locked after the locking bolt 5 passes through the second connecting hole of the lower clamping plate 1 and the upper connecting hole of the wing plate 4. Tightening nut 6 secures tool 9 to the derrick I-beam 10. When the path of the rope on the pulley needs to be changed, tool 9 can be disassembled and reinstalled on the derrick I-beam 10 with the set path. This allows tool 9 to be reused, reducing costs and preventing damage to the derrick I-beam 10. Due to the above structure, this utility model has the advantages of simple structure, fast installation speed, convenient disassembly, no change to the derrick structure, ensuring the strength of the derrick structure, performance safety, and cost saving.
