Double-inclined hydraulic type coating trolley system of marine pipeline concrete balance weight

Abstract

The invention relates to a double-inclined hydraulic type coating trolley system of a marine pipeline concrete balance weight. The double-inclined hydraulic type coating trolley system comprises two opposite coating trolleys and a straight line moving system for enabling the coating trolleys to walk. Each coating trolley is mainly composed of a height adjusting system, a rotating movement system and a pipeline pressing system. Taking one coating trolley as an example, the height adjusting system is located in the middle of the coating trolley, the rotating movement system is arranged at the top end of the height adjusting system, the height adjusting system is composed of a chute, a supporting column and two hydraulic cylinders, wherein the two hydraulic cylinders can be self-locked and are opposite to each other in an inclined mode, and an included angle from 60 degrees to 70 degrees is formed by the two hydraulic cylinders and the horizontal plane. The height and the wheel track of supporting wheels can be adjusted at the same time according to the fact that pipelines with different pipe diameters are retracted with different lengths. A pressing hub is pressed on the outer surface of the end portion of one pipeline and can rotate with the pipeline, and the pipeline can be prevented from jumping. The double-inclined hydraulic type coating trolley system can be suitable for the balance weight production requirement of serialization pipelines, and the purposes that the speed of the pipelines is adjustable and the direction of the pipelines is controllable are achieved.

Description

technical field [0001] The invention relates to a double oblique hydraulic coating trolley system for concrete counterweights of marine pipelines, which belongs to the scope of production equipment for counterweights of marine pipelines. Background technique [0002] Submarine oil pipeline is the main component of offshore oilfield development and production system. It is the fastest, safest and most economical and reliable transportation method for continuous delivery of large quantities of oil. Submarine pipelines can connect the production, transportation and storage systems of offshore oil fields, and also connect offshore oil fields with onshore oil industry systems. In recent decades, with the continuous development of offshore oil fields, submarine oil pipelines have actually become an effective means of transportation widely used in the offshore oil industry. [0003] Due to the influence of the marine environment, the ocean pipeline will drift due to the buoyancy ...

Problems solved by technology

When realizing the above functions, the current coating trolley system at home and abroad can only realize the concrete coating of a fixed diameter and length marine pipeline. When producing pipelines with different diameters and lengths, the equipment needs to be replaced, which seriously restricts marine distribution.
