Embodiment 1

[0065] like figure 1 As shown, this embodiment discloses an underwater pipe-laying robot, including a support structure 1, a pipe-laying adsorption platform 2, a pipeline trench excavation device 3, a dust cleaning device 4, a driving device 5, a crawler adsorption device 6, and a propulsion device 7; The pipe-laying adsorption platform 2 includes a pipe-laying rack 201, several electromagnet clips 202 and a first telescopic structure. The pipe-laying rack 201 is arranged on the top of the bracket structure 1 through several first telescopic structures, and several electromagnet clips 202 pass through a plurality of first telescopic structures. The first telescopic rods 203 are arranged on both sides of the inner wall of the pipe-laying frame 201; the pipeline trench excavation device 3 is arranged at the bottom of the support structure 1, and the pipeline excavation device includes several ground drilling structures 301 and second telescopic structures 302. Several ground dril...

Embodiment 2

[0068] like Figure 1 to Figure 8 As shown, this embodiment, on the basis of Embodiment 1, discloses an underwater pipe-laying robot, including a support structure 1, a pipe-laying adsorption platform 2, a pipe trench excavation device 3, a dust cleaning device 4, a driving device 5, and a crawler belt. The adsorption device 6, the propulsion device 7; the pipe-laying adsorption platform 2 includes a pipe-laying rack 201, several electromagnet clips 202 and a first telescopic structure, and the pipe-laying rack 201 is arranged on the top of the support structure 1 through several first telescopic structures, Several electromagnet clips 202 are arranged on both sides of the inner wall of the pipe-laying frame 201 through the first telescopic rods 203; the pipeline trench excavation device 3 is arranged at the bottom of the support structure 1, and the pipeline excavation device includes several ground drilling structures 301 and a second telescopic structure 301. Structure 302,...

Embodiment 3

[0085] like Figure 10 As shown, this embodiment, on the basis of Embodiment 2, discloses a pipe laying method of an underwater pipe laying robot, comprising the following steps:

[0086] S1: The underwater pipe-laying robot is adsorbed on the mother ship through the crawler adsorption device 6, and walks on the surface of the mother ship;

[0087] S2: Disconnect the power system of the crawler adsorption device 6, and the underwater pipe-laying robot cancels the adsorption on the surface of the mother ship, so that the mother ship can drop the underwater pipe-laying robot in the ideal placement position;

[0088] S3: The propulsion device 7 operates to push the underwater pipe-laying robot to move in the water;

[0089] S4: The underwater pipe-laying robot moves to the pre-laying position on the seabed through the driving device 5;

[0090] S5: The pipeline trench excavation device 3 drives the ground drilling structure 301 to loosen soil on the seabed according to the pres...

Abstract

The invention provides an underwater pipe laying robot and a pipe laying method thereof. The underwater pipe laying robot comprises a support structure, a pipe laying adsorption platform, a pipeline ditch excavating device, a dust cleaning device, a driving device, a crawler adsorption device and a propelling device. The crawler adsorption device and the propelling device are arranged, so that the underwater pipe laying robot walks on the mother ship to enter the water autonomously, the underwater pipe laying robot reaches the pipe pre-laying position and the recycling position through the propelling device, the manual carrying time is shortened, and the working efficiency is improved; the pipeline ditch digging device is arranged, so that the land on the seabed can be sufficiently loosened, and even the hard seabed or stones can be crushed; and through the pipe laying adsorption platform, the angle of the pipe laying frame can be changed, so that the pipeline can be more conveniently put into a pipeline ditch, and the pipe laying efficiency is improved.

Description

technical field [0001] The invention relates to the field of submarine pipeline laying equipment, and more particularly, to an underwater pipe laying robot and a pipe laying method thereof. Background technique [0002] In the deep sea, the pipeline burying operation is greatly affected by the environmental factors of the sea water. It is not possible to rely on the connection with the ship on the water surface to dig trenches like the shallow sea pipeline burial. Therefore, it is necessary to dig trenches that can be remotely controlled and have the ability to work autonomously. [0003] In the patent, a hydro-jet subsea trenching and pipe-laying robot includes a jetting system, a crawler walking system, a suction and lifting system, a pipe-laying system and a frame. The jetting system is used for deep trenching, including jetting Arm, nozzle, axial flow pump and retractable hydraulic cylinder; the crawler walking system is the walking power source of this trenching and pip...
