DETAILED DESCRIPTION

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0021] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0022] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0023] like Figure 1-3 As shown, the utility model provides an ultra-deep and ultra-heavy large-diameter steel pipe column positioning and fine-tuning device, comprising a tool section 1 located in a pipe insertion machine, a steel pipe column 13 connected to the tool section, a plurality of brackets 11 fixedly arranged on the outer periphery of the upper end of the steel pipe column 13, and a steel pipe column adjustment device arranged on the bracket, wherein the upper end of the tool section is connected to the clamping adjustment device of the pipe insertion machine, and the steel pipe column adjustment device adjusts the verticality of the steel pipe column by adjusting the distance from the casing.

[0024] In this embodiment, the intubation machine 3 is placed on the ground via a pad 7, which is then placed on the pad 7 via an outrigger cylinder 6. A verticality detection device is provided on the tool section for determining the verticality of the tool section and the steel pipe string. Specifically, the verticality detection device is a verticality sensor 2, which detects the verticality of the steel pipe string 13.

[0025] In this embodiment, the tool section 1 and the steel pipe column 13 are connected together by bolts to complete the connection between the tool section and the steel pipe column.

[0026] In this embodiment, the steel pipe string adjusting device includes a steel pipe string adjusting oil cylinder 12 and a steel pipe string adjusting pump station 9 for driving the steel pipe string adjusting oil cylinder. The steel pipe string adjusting pump station 9 is connected to the adjusting oil cylinder 12 through an oil pipe 10 .

[0027] In this embodiment, the clamping and adjusting device of the intubation machine is an adjusting oil cylinder, which also has 4-point clamping.

[0028] In this embodiment, four brackets 11 are evenly spaced around the upper periphery of the steel pipe column, and are arranged on the same horizontal plane. The brackets can be channel steel, which is welded to the steel pipe column. The regulating cylinder is placed within the channel steel.

[0029] During production, four brackets for placing hydraulic cylinders, i.e., channel steel, are first welded to the top of the steel pipe column 13. Then, the steel pipe column adjustment cylinder 12 is fixedly installed on the channel steel. The steel pipe column adjustment cylinder 12 is connected to the steel pipe column adjustment pump station 9 on the ground through an oil pipe. When the steel pipe column is lowered to the design elevation, the verticality sensor 2 pre-installed on the top of the column is used to observe the direction and deviation that need to be adjusted. The steel pipe column adjustment pump station 9 is operated to ensure that the verticality of the steel pipe column meets the design requirements. Finally, a pipe insertion machine is used to hold the steel pipe column 13[1] tightly to complete the lowering of the steel pipe column.

[0030] The specific adjustment process is as follows: the steel pipe string adjusting cylinder 12 acts on the casing 14 through the operation of the steel pipe string adjusting pump station 9, and the steel pipe string adjusting cylinder 12 and the intubation machine clamping adjustment device 5 jointly adjust the verticality of the steel pipe string 13. The verticality data of the steel pipe string 13 is fed back to the computer 8 in real time through the verticality sensor 2 bonded to the tool section 1 through the transmission line 4. When the verticality data meets the design requirements, the intubation machine holds the tool section 1 tightly to complete the adjustment.

[0031] The embodiments described above are only some of the embodiments of the present invention, not all of them. The detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
