Description

Petroleum steel pipe transmission mechanism with lifting function

Technical Field

The utility model belongs to oil steel pipe transmission equipment field especially relates to take lifting function's oil steel pipe transmission device, can make the oil steel pipe of waiting to carry along its axial transmission, reachs work platform after, steady place work platform on.

Background

Since the advent of polyurethane synthetic materials in the thirty years, polyurethane foam thermal insulation pipes have been developed as excellent thermal insulation materials, and their application range is becoming wider and wider, and they are also used in large quantities in various pipelines for transporting petroleum due to their remarkable energy-saving and corrosion-preventing effects. Because the polyurethane thermal insulation coating on the oil steel pipe is produced continuously, the coated oil steel pipe is required to be transferred from one station platform to the next station platform efficiently and stably. The mode of transporting includes the mode of rack transporting and plate turnover device transporting, if the mode of rack transporting is adopted, the petroleum steel pipe coated with polyurethane heat insulation material is shifted by a material shifting device arranged on an inclined rack, and then rolls on a working platform on the inclined rack, the mode has the advantages that firstly, the positioning is inaccurate, secondly, the rolling speed of the coated petroleum steel pipe on the inclined rack is overlarge, the coated petroleum steel pipe is easy to collide with equipment, and the polyurethane heat insulation coating is damaged or production accidents occur; if a flap is used, the flap can also damage the coated petroleum steel pipe coating when the coated steel pipe is lifted and dropped. In view of the above, it is desirable to invent a high-efficiency and smooth coated petroleum steel pipe transportation mechanism.
