Description

Anti-bottom-supporting integrated unreeling frame for flexible composite pipe Technical Field The utility model belongs to the technical field of pipeline construction, and particularly relates to an anti-bottom-supporting integrated unreeling frame for a flexible composite pipe. Background Existing pay-off and take-up rack for power take-up and pay-off two kinds of bobbins and unpowered pay-off frames: The power pay-off and take-up rack has the advantages that the power pay-off and take-up rack needs to provide rotating force, a motor, a speed reducer, a clamping device and a lifting device, the overall manufacturing cost is high, constant tension pay-off can be provided, the pipeline is not towed to the ground, but for pay-off, only one of the functions of the pay-off and take-up rack is utilized, the cost performance is low, and the power pay-off and take-up rack is more suitable for take-up. The unpowered pay-off rack has the advantages that the pay-off rack is unpowered, is free of a motor, a speed reducer, clamping and lifting functions because the pay-off rack is only provided with a simple frame, can only passively pay off through a production line tractor, is free of a brake device because the pay-off rack is free of an inertia effect, and can be loosened on a winding drum, so that the pipeline is in contact with the ground in the pay-off process, the surface of the pipeline is damaged, and the pipeline can be damaged and scrapped in serious conditions. In addition, the unpowered pay-off rack is split, the use characteristics of the unpowered pay-off rack are designed into an irregular shape, the center of gravity is not centered, the transferring and placing process is uncontrolled, and the rack bodies on two sides are aligned and placed according to a certain distance, so that time and labor are wasted. Disclosure of utility model The utility model aims to solve the defects in the prior art, provides the anti-bottom-supporting integrated unreeling frame for the flexible composite pipe, solves the problems of difficult hoisting, difficult placement, supporting and the like in the prior art, reduces the difficulty of manual operation, improves the operation efficiency, increases the design of anti-bottom-supporting, and avoids the situation that a pipeline is towed to the ground, worn on the surface or folded and scrapped due to inertia in the paying-off process. According to the technical scheme, the bottom supporting prevention integrated unreeling frame for the flexible composite tube comprises two unreeling frame supports which are oppositely arranged, a threading rod is arranged on each of the two unreeling frame supports, a plurality of carrier rollers are arranged between the bottoms of the two unreeling frame supports, and a certain distance is reserved between the plurality of carrier rollers. In some embodiments, the pay-off rack comprises a bottom frame, a diagonal support and a vertical support fixedly connected to each other. In some embodiments, the diagonal and vertical supports are fixed or telescoping structures. In some embodiments, the diagonal brace is provided with a lifting point. In some embodiments, the axle rod is free to rotate and has two ends detachably connected to the top of the vertical support.
