Description

Technical Field

[0001] The present invention relates to the technical field of power cable protection tubes, and in particular to equipment and a method for producing and processing drag-reducing flame-retardant cable protection tubes. Background Art

[0002] With the rapid development of our communications industry, the demand for cable protection tubes is increasing. Cable protection tubes are mainly used for guiding, isolating, and protecting optical fibers, as well as for laying cables and optical fibers for telecommunications, cable television signals, metropolitan area network cables, and power sector cables. Cable protection tubes are mainly installed underground or on the surface to protect cables from corrosion and damage. They prevent power line disconnections and short circuits, which can cause communication cables and wire ropes to become live. They protect cables, switches, core boards, and even the entire device from burning out, and they also provide a certain degree of isolation from magnetic field interference from power lines. Cable protection tubes are generally required for use in various harsh environments, including the seabed, snow, and saline-alkali environments. However, due to the harsh operating environment, cable protection tubes are easily worn during movement, and existing cable protection tubes have poor corrosion resistance, which reduces the service life of cable protection tubes.

[0003] In order to solve the above problems, the present invention provides a drag-reducing flame-retardant cable protection tube production and processing equipment and method, which increases the drag reduction performance of the inner wall by adding lubricant or applying a drag-reducing coating after grinding the inner wall of the cable protection tube, and at the same time applies an anti-corrosion layer on the outer wall of the cable protection tube, so that the inner wall of the protection tube is smooth and flawless, and the outer wall is corrosion-resistant, with excellent heat resistance, flame retardancy, corrosion resistance, and drag reduction; at the same time, it can also adapt to the inner walls of cable protection tubes of different sizes.

The oil pipe 203 pushes the nozzle mechanism 201 and the grinding mechanism 202 to move toward the center of the cable protection tube; when they reach the middle position, the front motor 7 reverses, and the nozzle mechanism 201 and the grinding mechanism 202 are pulled back to the end position of the cable protection tube; the rear motor 7 reverses after the nozzle mechanism 201 and the grinding mechanism 202 on the rear side grind the center position of the cable protection tube and spray lubricating liquid, and then pulls it back to the end position of the cable protection tube;

[0076] Step e: activating the electric clamp 4022 to secure one end of the wire mesh, activating the electric screw device 4031, and synchronously activating the motor 3 304 and the spray head 2 305 to simultaneously wind the wire mesh around the outside of the cable protection tube and spray anti-corrosion paint on the outside of the cable protection tube; after the wire mesh is wound, activating the cylinder 2 4011 to cut the wire mesh; and the electric screw device 4031 drives the winding mechanism 3 to reset.

[0077] In step f, the lifting platform 102 and the clamp mechanism 103 are started to clamp the completed cable protection tube, and then the opening mechanism 4 is reset, the multi-stage electric cylinder 105 is reset, and the motor 7 is started to pull the nozzle mechanism 201 and the grinding mechanism 202 back to the initial position; the lifting platform 102 is reset, the clamp mechanism 103 is reset, and the completed cable protection tube is manually removed.
