Embodiment Construction
[0023] A self-vibrating immersed pipe machine for laying submarine pipelines and its use method. Its overall structure includes five parts: a vibration exciter sleeve, a vibration foot, a reaction arm, a crawler chassis, and a hydraulic reaction telescopic arm.
[0024] The exciter sleeve 1 in the structure is a cylindrical structure, which adopts a horizontal form and is consistent with the direction of the submarine pipeline. There is an eccentric balance wheel in the exciter sleeve 1. After high-frequency rotation, high-frequency vibrations in the vertical direction will be generated. Exciting force, the exciter sleeve 1 is connected to the mother ship through the towing cable 2, and transmits control information and power energy;
[0025] The vibration pad 3 in the structure is a device for transmitting high-frequency vibration force. It is located at both ends of the exciter sleeve 1 and forms an arc-shaped pad downward, which can be in close contact with the submarine pip...

The invention provides a self-vibration immersed pipe machine for submarine pipeline burying and a using method thereof. A grooving machine is composed of two parts, namely a pipeline excitation module and a crawler-type self-propelled bottom plate, wherein the pipeline excitation module is composed of a vibration exciter sleeve, a vibration foot pad and a counterforce arm; and the crawler-type self-propelled bottom plate is composed of a crawler travelling bottom plate and a hydraulic counterforce stretchable arm; and the overall structure is controlled in a ship dragging mode, a control cable is connected to the vibration exciter sleeve, and the travelling posture and a working state of the whole structure are controlled. The machine and the method are applied to the engineering of fastlaying of the submarine pipeline, the underwater construction of a diver is not needed, the machine is controlled to carried out automatic construction on a ship, the construction speed is high, a lotof labor cost is saved, and the construction efficiency and the construction precision degree are improved.
Description
technical field [0001] The invention relates to a self-vibrating pipe sinking machine used for laying submarine pipelines and a use method thereof. The slotting machine consists of two parts: the pipeline excitation module and the crawler self-propelled chassis. The pipeline excitation module is composed of a vibration exciter sleeve, a vibration pad and a reaction arm; the crawler self-propelled chassis is composed of a crawler chassis and a hydraulic reaction telescopic arm. The overall structure is controlled by the way of ship towing, and the control cable is connected to the exciter sleeve to control the walking posture and working state of the whole structure. The self-immersed pipe machine straddles the pipeline exposed on the seabed, presses the pipeline at a predetermined position through the vibration pad, and applies high-frequency vibration from the vibration-exciting balance wheel in the exciter sleeve, and transmits it to the sea below it through the pipeline. ...
