Embodiment Construction

[0010] The invention relates to a manufacturing method of an anti-wind and rain vibration embossed HDPE cable sheath pipe. It installs a molding device outside the head of a plastic extruder, and utilizes the residual temperature of the HDPE round pipe itself to rely on 4 to 8 molding devices. Rollers that are evenly distributed on the circumference, with convex nails on the outer edge, and can rotate around their own axes extrude the HDPE round pipe. The HDPE round pipe advances in a straight line to drive the rollers to rotate synchronously, so that the outer surface of the HDPE round pipe is synchronously formed according to certain rules and shapes. Dimples, and through cooling and shaping, it is made into anti-wind and rain vibration embossed HDPE cable sheath tube. According to the diameter of the HDPE round pipe, the number and arrangement of the rollers on the forming device can be adjusted to produce various specifications of anti-wind and rain vibration embossed HDPE ...

Abstract

The invention relates to a method for manufacturing a wind-rain vibration resistant embossing HDPE cable protecting sleeve. The method comprises: arranging a forming device on the outside of a machine head of a plastic extruder; extruding an HDPE circular pipe through 4 to 8 rollers which are evenly distributed on the forming device by circle, provided with convex nails on the outer edges and can rotate around a self axis by making use of the self residual heat of the HDPE circular pipe; making the outer surface of the HDPE circular pipe synchronously form concave pits which are arranged according to specified regulation and shape; and forming the HDPE circular pipe through cooling to obtain the wind-rain vibration resistant embossing HDPE cable protecting sleeve. The method makes full use of self heat of the HDPE circular pipe and has the advantages of energy resource conservation, convenient operation, good forming performance of the concave pits on the HDPE pipe and stable quality.

Description

(1) Technical field [0001] The invention relates to a manufacturing method of components used in cable-stayed bridge engineering, in particular to a manufacturing method of a wind-rain vibration-resistant embossed HDPE cable sheathing tube for parallel steel strand cable-stayed cables. (2) Background technology [0002] Stayed cables are the lifeline of a cable-stayed bridge. Due to the long cable body of long-span cable-stayed bridges, under the joint action of wind and rain, the cable-stayed cables will vibrate, which will affect the safety of the bridge structure. Therefore, the stay cables used in long-span cable-stayed bridges generally take measures on the cable body to destroy the wind and rain vibration frequency that causes the cable to vibrate, so as to suppress the vibration. There are two types of commonly used anti-wind and rain vibration stay cables: embossed stay cables and double helix stay cables. The embossed cable is to set pits arranged according to a c...
