A marine weight pipe coating trolley

Abstract

The invention relates to a novel marine counterweight pipe coating trolley, which is mainly composed of hydraulic motors, supporting hydraulic cylinders, supporting wheels, bases, supporting seats, a control cabinet, a lifting platform, a lifting hydraulic cylinder, scissors fork arms, a chassis, wheels, a walking hydraulic motor, retractable supporting legs and weighing sensors; the supporting wheels are two pairs of supporting wheels different in spacing; the supporting wheels at a large spacing therebetween are used for supporting a large-caliber pipe, while the supporting wheels at a small spacing therebetween are used for supporting a small-caliber pipe; the supporting seats can be adjusted by certain angles by means of expansion and contraction of piston rods of the supporting hydraulic cylinders, such that an application range to pipes is widened; a pipe casting height of the lifting platform is realized by means of a hydraulic support-scissors fork machine lifting structure, which has good stability; the weighing sensors are capable of weighing cast concrete in real time during pipe coating, and the control cabinet is capable of controlling a rectilinear motion speed, a pipe rotating speed and a lifting height of the coating trolley in real time according to feedback data from the weighing sensors. The coating trolley provided by the present invention is wide in pipe application range, capable of weighing the coated concrete in real time, stable in mechanical structure, and high in automation degree.

Description

technical field [0001] The invention relates to a trolley for coating marine counterweight pipes, which belongs to the category of counterweight production equipment for marine pipelines. 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, and at the same time play a role of mechanical protection to prevent damage from external factors (such as anchors and tides). [0003] At present, in China, the concrete counterweight technology for marine pipelines is not yet perfect, and there is no real marine pipeline construction enterprise, and most of them rely on foreign countries for equipment and construction standards. Concrete coating equipment is the key to the production line of concrete counterweights for marine pipelines. How to use reasonable techniques to evenly coat concrete on the surface of pi...
