Results of research of working capability of refined pipelayer equipment

摘要

The paper proposes a new variant of additional support improvement of the pipelayer boom. The supposed technical solution allows one to increase smoothing and stability of pipelayer operation. The result is achieved by adding extra elements into the construction of the pipelayer boom support. The proposed construction presupposes that cargo boom will be joined with the pipelayer support, which consists of a hydraulic cylinder and a metal base, used for cylinder fixation to the support with bolted-type connection. The relations, gained from the computed pattern of the pipelayer working equipment, are given to prove the efficiency of the proposed design solution. The calculated relations allow defining the size of the loads applied on the pipelayer. The results of the theoretical research, carried out in Solid works, are demonstrated in graphics, and it shows the stresses, shifts and deformations in boom design of the pipelayer used for long-distance pipeline placement The additional advantage is that the size of the strength margin in the support structure of the pipelayer boom was obtained due to the conducted research.
