Pipeline expansion joint based on damping of hoisting structure

Abstract

The utility model relates to the technical field of expansion joints, and discloses a pipeline expansion joint based on damping of a hoisting structure, which solves the problem that a corrugated pipe is inconvenient to limit quickly at present, and comprises the corrugated pipe, and a flange plate I and a flange plate II are fixedly mounted at two ends of the corrugated pipe respectively. A limiting mechanism is connected between the first flange plate and the second flange plate and comprises a sleeve installed on the outer side of the first flange plate, a connecting rod is installed at one end of the sleeve, and hanging rings are fixedly installed on the side, away from the corrugated pipe, of the connecting rod at equal intervals. According to the utility model, through the cooperation among the sleeve block, the rotating shaft and the sleeve, the connecting rod can be conveniently rotated to be attached to the guide rod and the supporting block, and through the cooperation among the guide block and the spring I and the cooperation among the limiting rod and the limiting block, the positioning column can be conveniently inserted into the corresponding positioning hole, so that the flange plate I and the flange plate II can be connected; and therefore, the corrugated pipe can be conveniently and quickly limited and prevented from being pressed and deformed.
