Abstract
The invention discloses an inner diameter expander for external butt fusion of butt-joint positions of large-diameter plastic pipelines. The expander comprises a lantern ring, wherein a plurality of fixed supporting rods are evenly, fixedly and circumferentially arranged on the outer ring surface of the lantern ring, sliding grooves are formed in the fixed supporting rods, sliding supporting rods capable of sliding freely along the sliding grooves are arranged in the sliding grooves, arc-shaped supporting plates are connected with ends of the sliding supporting rods, a screw capable of being rotated freely is connected in the lantern ring in a sleeved manner, a nut is in threaded connection with the screw, and supporting rods are connected between the nut and the sliding supporting rods. Problems are solved. By means of the inner diameter expander for external butt fusion of the large-diameter plastic pipelines, the butt-joint positions of the two large-diameter plastic pipelines are attached closely, and gaps are reduced, so that sealing butt joint of the butt-joint positions of the plastic pipelines through external fusion gluing is greatly facilitated, and the construction efficiency and the construction quality of the large-diameter plastic pipelines during butt-joint construction are greatly improved.
