Description

Technical Field

[0001] This utility model relates to the field of drilling support frame technology, and in particular to a stable drilling support frame for rocky seabeds. Background Technology

[0002] Drilling support frames are fundamental support equipment in drilling operations, primarily used to stabilize drilling equipment, transfer and distribute drilling loads, and ensure drilling accuracy and operational safety. They provide guiding support for the drill string and require sufficient torsional stiffness. The key characteristics that distinguish rocky seabeds from ordinary seabeds include their irregular surface height and high rock hardness.

[0003] In the existing technology, when drilling on rocky seabeds, drilling support frames are needed to support and limit the drill bit. However, the existing drilling support frames are square, requiring multiple drilling points for fixation or welding of multiple steel piles for anchoring, which is cumbersome. At the same time, it is inconvenient to disassemble and maintain the drill bit casing, and wear makes replacement difficult. Therefore, it is necessary to propose a stable drilling support frame for rocky seabeds to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable drilling support frame for rocky seabeds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stable drilling support frame for rocky seabed includes a support pipe and a disassembly / assembly assembly for disassembling the support pipe. The disassembly / assembly assembly is disposed on the outer circular wall of the support pipe. The disassembly / assembly assembly includes: a support base disposed on the outer circular wall of the support pipe; a support top seat fixedly installed on the top surface of the support base; a plurality of support plates fixedly installed on the outer circular wall of the support pipe; a plurality of fixing plates fixedly installed on the outside of the support top seat; a second threaded hole is respectively opened on one side of the fixing plate and on three sides of the support base; a plurality of threaded grooves are opened on one side of the support plate; bolts are threadedly connected to the inner circular wall of the second threaded hole, and the bolts are threadedly connected to the threaded grooves.

[0007] As a further embodiment of this utility model, the support base is externally fixedly equipped with several mounting feet, and the top surface of each mounting foot has two mounting holes.

[0008] As a further embodiment of this utility model, a reinforcing rib is fixedly installed on the top surface of the mounting foot, and the reinforcing rib is fixedly installed with the support base.

[0009] As a further embodiment of this utility model, the horizontal cross-section of the support top seat and the support base is triangular, and the support top seat is a triangular frustum shape.

[0010] As a further embodiment of this utility model, a first connecting plate and a second connecting plate are fixedly installed on the three internal sides of the support base, and a first threaded hole is provided on one side of the first connecting plate and the second connecting plate, and the first threaded hole is threadedly connected to the bolt.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By using the support pipe, support base, support top, support plate, fixing plate, and bolts in conjunction with each other, the support pipe can be disassembled and assembled. The support pipe can be disassembled by simply tightening the bolts, making replacement convenient for maintenance. At the same time, the number of installation points has been reduced from four to three, reducing the need for drilling or setting steel pile anchor points, which is more convenient to use. The triangular cross-section of the support base and support top improves structural stability, and the upward tapering of the top of the support base further ensures the stability of the support pipe and guarantees the support effect.

[0021] Reference Figures 1-4 A stable drilling support frame for rocky seabed includes a support pipe 1 and a disassembly and assembly assembly for disassembling and assembling the support pipe 1. The disassembly and assembly assembly is disposed on the outer circular wall of the support pipe 1. The disassembly and assembly assembly includes: a support base 2, which is disposed on the outer circular wall of the support pipe 1. A support top seat 3 is fixedly installed on the top surface of the support base 2. Several support plates 4 are fixedly installed on the outer circular wall of the support pipe 1. Several fixing plates 5 are fixedly installed on the outside of the support top seat 3. Second threaded holes 8 are respectively opened on one side of the fixing plates 5 and on three sides of the support base 2. Several threaded grooves 14 are opened on one side of the support plates 4. Bolts 6 are threadedly connected to the inner circular wall of the second threaded holes 8. The bolts 6 are threadedly connected to the threaded grooves 14.

[0022] In this embodiment, a plurality of mounting feet 11 are fixedly installed on the outside of the support base 2. Two mounting holes 12 are opened on the top surface of the mounting feet 11. A reinforcing rib 13 is fixedly installed on the top surface of the mounting feet 11. The reinforcing rib 13 is fixedly installed with the support base 2. The horizontal cross-section of the support top seat 3 and the support base 2 is triangular. The support top seat 3 is in the shape of a triangular frustum.

[0023] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0024] The support pipe 1 is used to support the drill pipe equipment. When the user replaces the support pipe 1, the bolt 6 is turned out of the threaded groove 14 and the first threaded hole 7, thereby releasing the fixation of the support plate 4. After removing all the bolts 6, the support pipe 1 can be lifted and moved upward to be removed from the inside of the support base 2. During installation, the new support pipe 1 and support plate 4 are inserted into the inside of the support base 2 in the same way as described above. The bolts 6 are tightened into the second threaded hole 8, the first threaded hole 7 and the threaded groove 14 to complete the fixation. During installation, the support base 2 is placed on the rocky seabed, and expansion bolts or welded steel piles are driven into the mounting holes 12 of its external mounting feet 11 for anchoring. The number of installation points is reduced from four to three, reducing the number of steel pile anchoring points that need to be drilled or set. The triangular support base 2 and support top 3 improve the structural stability. At the same time, the top of the support base 2 is set upward to further ensure the fixation stability of the support pipe 1.
