Lifting device for oil pipeline installation and laying

Abstract

The invention discloses a lifting device for installing and laying an oil pipeline. The lifting device structurally comprises a lifting device main body, a walking beam control transmission mechanism,a mechanical arm control transmission mechanism and an internal control mechanism. The mechanical arm control transmission mechanism is provided with a walking beam transmission assembly, a control main arm rod, a mechanical arm hydraulic fixing device and an adjustable movable mechanical claw. The internal control mechanism is provided with a control trigger handle, an internal clamping rod fixing device, a gear control clamping rod transmission device and an auxiliary pushing plate device. The auxiliary pushing plate device is provided with an auxiliary pushing plate and a strong reset spring set, so that when the lifting device is used, the distance and the height of the mechanical claw can be conveniently adjusted when the oil pipeline is laid, at the same time, the size and tightnessof the mechanical claw can be conveniently adjusted, the oil pipeline can be flexibly laid, the butt joint of the pipeline is more accurate, and at the same time, the lifting device can be suitable for the installation of a multi-pipe diameter oil pipeline.

Description

technical field [0001] The invention relates to a lifting device for installing and laying oil pipelines, which belongs to the field of installing and laying oil pipelines. Background technique [0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as "industrial blood". There are oil reserves in some areas of the upper crust, and the main components are various alkanes, cycloalkanes, and aromatic hydrocarbons The oil-forming mechanism of petroleum has two theories of biosedimentary oil and petrochemical oil. The former is more widely accepted. It is believed that oil is formed by organisms in ancient oceans or lakes after a long evolution. It belongs to biosedimentary oil and is non-renewable. , the latter believes that petroleum is generated from the carbon in the earth's crust itself, has nothing to do with biology, and is renewable. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many...
