Abstract
In order to optimize the technological operations of oil and gas pipeline construction (loading, transportation and installation), an integrated system with the introduction of partial automation elements is proposed, implemented in the form of a semi-automated loading and transport unit. The design scheme of the unit is based on two manipulators of a sequential structure, the ends of which are equipped with clamp-type grappling devices. A distinctive feature of the loading and transport unit design is the presence of an annular welding machine in one of the lifting mechanisms. Partial automation of the process consists in the fact that welding of the mounted elements, return of the manipulators to their original position at specified coordinates and capture of the pipeline from the body are carried out automatically, which increases the productivity of the proposed unit design.
The technological process of moving laying and installing pipes using the mechanism developed by the authors is considered. A theoretical service area with a numerical solution in the MathCAD software package is calculated. A kinematic analysis of the mechanism was carried out with the determination of the speeds and accelerations of the actuating links. As a result, the performance coefficient of the proposed semi-automated loading and transport unit K = 2.4 was established in comparison with the basic analog of the pipelayer – CHTZ/TR12/TR20.
