Embodiment Construction

[0020] Attached below Figure 1-3 The present invention will be described in detail.

[0021] Such as figure 1 As shown, the present invention provides a method for covering the cable body with PVF film. The length of the PVF film matches the length of the cable body, and the wide edge of the PVF film is coated along the circumference of the cable body. This method utilizes the self-adhesiveness of the PVF film to be better than the adhesion to the cable body to ensure that the PVF film will not fall off from the cable body; at the same time, the length of the PVF film is customized according to the length of the cable body, and the winding film disc does not need to be rotated , so the size of the stretch film disc is not affected. This avoids multiple replacements of the stretch film discs.

[0022] Such as figure 2 As shown, the present invention provides a kind of method that PVF film coats the cable body, adopts a plate of PVF film (2) to coat the cable body (1), the...

Abstract

The invention discloses a method for coating an inhaul cable body with a PVF film. The method is that inhaul-cable-surface coating is carried out through the PVF film with one width, and inhaul-cable-surface one-overlapping-one coating is carried out through PVF films with two widths; coating is carried out through the width of the PVF film in the circumference of a cable body, and overlapping joint or non-overlapping joint is formed on the two sides of the width of the PVF film. By means of the method, the construction speed can be higher, the efficiency can be higher, the personnel security can be better guaranteed, and the construction engineering cost can be lower.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a method for covering a cable body with a PVF film. Background technique [0002] At present, in order to improve the service life of the cable, PVF film is often wound on the surface of the cable, and the ultraviolet rays are isolated through the PVF film, so that the cable body of the cable has a longer service life. For example, the patent application with the publication number "CN101230559A" discloses a method of wrapping PVF fluoride film tape on the outer surface of the cable-stayed cable and then winding the spiral rib. Wrap a layer of PVF fluorinated film protective tape, and finally wrap the spiral rib outside the PVF tape. [0003] For the winding method, the construction speed is mainly affected by the two parameters of the winding rotation speed and the winding pitch. Since the operation is at high altitude and the rotating disk needs to rotate...
