Self-adjusting pipe counterweight coating trolley

Abstract

The invention relates to a self-adjustable pipeline weight coating trolley which is mainly composed of a rotating movement system, a scissor-fork type lifting platform, a real-time weighing system and a control system. A main supporting wheel and an auxiliary supporting wheel with different spacing sizes are arranged on the same coating trolley, and the coating trolley has a self-adjustable function aiming at pipelines with different pipe diameters. The large-spacing main supporting wheel supports the pipeline with the large pipe diameter, and the small-spacing auxiliary supporting wheel supports the pipeline with the small pipe diameter. A lifting system adopts a scissor-fork mechanical structure and has a good stability, and a telescopic landing leg is mounted at the outer part of a chassis and is used for preventing rolling over and overturning. A weighing sensor monitors the weight of concrete in real time, and the control system adjusts the linear motion speed and the rotation speed of the coating trolley in real time according to the feedback data of a sensor. The while coating trolley has high degree of automation, greatly improves the production efficiency of concrete in the pipeline coating process, and reduces the production cost.

Description

technical field [0001] The invention relates to the field of engineering application and belongs to the category of pipeline counterweight production equipment. Background technique [0002] Affected by the marine environment, the laying of marine pipelines will drift due to the buoyancy of seawater. Concrete counterweighting of marine pipelines is an effective way to overcome buoyancy of the ocean to prevent drifting, and at the same time increase mechanical protection to prevent damage from external factors (such as anchors and tides). [0003] Offshore pipeline concrete counterweight technology has been widely used abroad, and the most famous ones are offshore oil production areas, such as the Persian Gulf, the UK and the Norwegian North Sea oilfields, where large-scale submarine pipeline projects have been built. At present, in China, the concrete counterweight technology for marine pipelines is not yet perfect, and there is no real marine pipeline construction enterpri...

AI Technical Summary

Problems solved by technology

In order to coat pipes efficiently, the amount of concrete required for the production of pipes with different diameters is different. Therefore, the projected height and movement speed required by the technical requirements are different. When producing pipes with different diameters, equipment needs to be replaced, which seriously restricts marine counterweights. Tube production efficiency and popularization and application
