Installation lifting device for laying of petroleum pipes with different diameters

Abstract

The invention discloses an installation lifting device for laying of petroleum pipes with different diameters. The device comprises a support frame; a transverse frame is mounted at the upper end of the support frame; a guide block is mounted at the middle part of the lower end of the transverse frame; a screw rod is mounted at the middle part of the guide block; a driving disc is mounted at the left end of the screw rod; the lower end of the guide block is hinged with a first pull rod; a lifting plate is mounted at the lower end of the first pull rod; a fixed cylinder is mounted at the middlepart of the lower end of the lifting plate; a lead screw is mounted in the fixed cylinder; a lifting block is mounted at the middle part of the lead screw; hinge rods are mounted at the left and right ends of the lifting block; second pull rods are mounted on the outer sides of the hinge rods; clamping rods are hinged to the lower ends of the second pull rods; clamping rings are mounted on the inner sides of the clamping rods; and a fixed block is mounted at the bottom end of the fixed cylinder. The device realizes lifting of the petroleum pipes with different diameters, effectively preventsthe petroleum pipes from shaking left and right in the lifting process, can stably feed the petroleum pipes to the installation position, and meanwhile, reduces the labor intensity of workers.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to an installation and lifting device suitable for laying petroleum pipelines with different diameters. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. The nature of petroleum varies with the place of origin, the viscosity range is very wide, the freezing point varies greatly (30-60 degrees Celsius), the boiling point ranges from room temperature to above 500 degrees Celsius, it is soluble in many organic solvents, insoluble in water, but can form with water emulsion. However, the composition and appearance of oil in different oil fields can be greatly distinguished. Petroleum is mainly used as fuel oil and gasoline, and fuel oil and gasoline constitute one of the most important primary energy sources in the world. Petroleum is also a raw material for man...

AI Technical Summary

Problems solved by technology

[0003] Oil relies on oil pipelines to transport oil. When oil pipelines are installed, lifting devices are often required to hoist the oil pipelines to the installation height for installation. Most of the traditional lifting devices use ropes to cover the oil pipelines. During the lifting process, it is easy to shake, and the oil pipeline cannot be installed accurately, which reduces the work efficiency, or the oil construction workers manually lift the pipeline to the construction site piece by piece, which seriously increases the labor of the workers. strength, poor usability
