Abstract

A lifting device used for installation and pavement of petroleum pipelines is disclosed. The device includes a fixed base, a rotating table, a supporting vertical column, an amplitude changing oil cylinder, a hydraulic telescopic bar, a movable connecting block, a lower lifting telescopic arm, an upper lifting telescopic arm, a pipeline clamp, a limiting block and reinforcing plates. The pipelineclamp is disposed between the upper and lower lifting telescopic arms, and includes a pressure mechanism, a main transmission shaft, an overload protective mechanism, a mounting base, a lifting hydraulic oil cylinder, a left locking mechanism, left clamping arm, right clamping arm, a right locking mechanism, and a lifting hydraulic telescopic bar. The device is provided with the pressure mechanism, the overload protective mechanism and the locking mechanisms, early warning of overload of the pipeline is achieved, and automatic locking ensures that lifting stability of the pipeline is not influenced by tiny vibration in a lifting process, thus improving lifting safety for the pipeline.

Description

technical field [0001] The invention relates to a hoisting device for installing and laying oil pipelines, which belongs to the field of installation and laying equipment for oil pipelines. Background technique [0002] The pipes of oil pipelines are generally steel pipes, which are connected to long-distance pipelines by welding and flange connection devices, and valves are used for opening and closing control and flow regulation. Oil pipelines mainly include isothermal transportation, heating transportation and sequential transportation. Pipeline corrosion and how to prevent corrosion is one of the important links in pipeline maintenance. At present, oil pipelines have become one of the main transportation tools for oil, and they still have considerable development potential in the future. [0003] The existing oil pipeline installation and laying lifting device adopts the traditional truck crane method for pipeline installation and laying, which lacks an overload warnin...
