Carrying and lifting device for mechanical petroleum pipeline installation

Abstract

The invention discloses a carrying and lifting device for mechanical petroleum pipeline installation. The carrying and lifting device comprises a support frame, a transverse frame is installed at theupper end of the support frame, guiding blocks are installed in the middle of the lower end of the transverse frame, a screw is installed in the middles of the guiding blocks, and a driving disc is installed at the left end of the screw; and a first pulling rod is hinged to the lower end of each guiding block, a lifting plate is installed at the lower ends of the first pulling rods, fixing rods are installed on the two sides of the lower end of the lifting plate, a clamping rod is hinged to the bottom end of each fixing rod, a second pulling rod is hinged to the upper end of each clamping rod,a lifting rod is hinged to the upper ends of the second pulling rods, a lifting block is installed in the middle of the lifting rod, a lead screw is connected to the middle of the lifting block through a threaded hole, and a driving motor is connected to the upper end of the lead screw. According to the carrying and lifting device for mechanical petroleum pipeline installation, lifting of petroleum pipelines with different diameters is achieved, left-right waggling generated in the lifting process of the petroleum pipelines is effectively avoided, and then the petroleum pipelines can be precisely delivered to the installing positions; meanwhile, the labor intensity of workers is reduced, the petroleum pipeline laying requirements are met, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of oil pipeline installation, in particular to a mechanical handling and lifting device for oil pipeline installation. 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 Emulsions, but the composition and appearance of oil from different oil fields can be very different. [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 traditi...

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
