Bent pipe bearing and dragging device capable of moving in circular arc mode

Abstract

The invention belongs to the technical field of bent pipe load-bearing trailers in circular arc motion, and relates to a bent pipe load-bearing dragging device in circular arc motion, a dragging vehicle I and a dragging vehicle II are arranged at the lower part of the left end of a bent pipe, and a flexible supporting device I and a flexible supporting device II are fixedly arranged at the lower part of the right end of the bent pipe; the rotary traction cylinder is fixedly arranged at the corresponding position of the front side of the winding disc, the first flexible supporting device is fixedly arranged at the front side position of the right end of the bent pipe, and the second flexible supporting device is fixedly arranged at the rear side position of the first flexible supporting device; the first dragging vehicle is arranged on the front side of the left end of the bent pipe, and the second dragging vehicle is arranged on the rear side of the first dragging vehicle. According to the flexible supporting device, driving traction on the bent pipe is achieved, the radius of arc motion of the bent pipe can be changed according to different bending degrees of the bent pipe, adaptive supporting on the bent pipes with different bending degrees is improved, the flexible supporting device and a dragging vehicle are better in adaptive matching, and the integrity and stability of the flexible supporting device, the dragging vehicle and a winding device are improved.

Description

technical field [0001] The invention belongs to the technical field of curved pipe load-bearing trailers with arc motion, and in particular relates to a curved pipe load-bearing dragging device with circular arc motion. Background technique [0002] In order to improve the service life and anti-corrosion performance of the elbow during the processing of the elbow, so as to adapt to the humid and corrosive underground environment of the elbow, it is necessary to wrap a layer of anti-corrosion tape on the surface of the elbow to improve the use of the elbow. longevity and corrosion resistance. The winding of the anti-corrosion tape for the elbow requires a special anti-corrosion tape winding equipment, which automatically wraps the anti-corrosion tape from one end of the elbow to the other end of the elbow. [0003] Since the elbow has a certain degree of curvature, when the elbow slowly passes through the center of the winding disk of the anti-corrosion tape winding device, ...
