The invention discloses a convenient-to-operate pipeline conveying device, which comprises a bottom plate, wherein rolling wheels are arranged at the bottom of the bottom plate; the upper end of the bottom plate are symmetrically provided with two side plates; at least two fixing plates are vertically arranged between the two side plates; the fixing plates are in mutual parallel arrangement; downward recessed arc-shaped fixing grooves are formed in the fixing plates; an arc-shaped plate matched with the arc-shaped fixing groove is hinged onto each fixing plate; a clamp block is arranged on the non-hinging end of each arc-shaped plate; and a clamp groove matched with the clamp block is arranged on each fixing plate. The clamping fixation of a petroleum pipeline is realized through the arrangement of mutually matched arc-shaped plates and arc-shaped fixing grooves, so that the problem of slide falling of a petroleum pipeline in the moving process of a moving mechanism is solved.
