An automatic drilling machine for underwater pipelines

Abstract

The invention provides an underwater pipeline automatic drilling machine. The underwater pipeline automatic drilling machine comprises a steel wire rope guiding mechanism, a feeding driving mechanism,a drilling driving mechanism, a clamping mechanism, a pipeline positioning mechanism and an upper and lower bracket, wherein the upper and the lower support form a machine body main body part througha pin shaft, the steel wire rope guide mechanism, the pipeline positioning mechanism, the feeding driving mechanism and the drilling driving mechanism are arranged on the body part of the machine body. The underwater pipeline automatic drilling machine are used for achieving drilling work of pipelines with different sizes at one time; the system can be automatically controlled and can be operatedby an ROV, the pipeline positioning mechanism, a steel wire rope tightening mechanism can select different driving modes under different working conditions, the application is flexible, and underwater operation is facilitated; and the underwater pipeline automatic drilling machine can adapt to the narrow working environment of the seabed pipeline and the ground space.

Description

technical field [0001] The invention relates to a drilling machine, in particular to an underwater pipeline drilling machine. Background technique [0002] The underwater pipeline automatic drilling machine is used in special fields such as the maintenance of submarine pipelines due to its good quality of pipeline processing, convenient operation, wide range of operating objects, and light and convenient structure. The underwater pipeline automatic drilling machine is usually carried by ROV (Underwater Cable Robot), and assists in the operation for underwater operations. Due to the complex nature of the working environment of the submarine pipeline, the variability of the pipeline size, and the narrow space between the pipeline and the seabed, the drilling rig has a huge workload on the drilling operation, and the drilling rig often has to be carried out many times due to the change in the size of the pipeline that needs to be drilled. The salvage adjustment is decentralize...

AI Technical Summary

Problems solved by technology

Due to the complex nature of the working environment of the submarine pipeline, the variability of the pipeline size, and the narrow space between the pipeline and the seabed, the drilling rig has a huge workload on the drilling operation, and the drilling rig often has to be carried out many times due to the change in the size of the pipeline that needs to be drilled. The salvage adjustment is lowered, which greatly affects the operation efficiency; when the space between the pipeline and the seabed is narrow or the equipment fails, the ROV cannot complete the auxiliary function, and must be operated by divers, causing a series of problems such as cumbersome work and injuries to operators.
