Problems solved by technology

[0002] It is well known that cables buried in underground tunnels, first, the flame retardant coating on the surface of the cable will be damaged due to bumps during laying, and second, oxidation-reduction reactions are prone to occur in humid environments, resulting in damage to the surface of the cable. Part of the flame retardant coating is damaged, and the third is that after a long time, the flame retardant coating on the surface of the cable will fall off, so it is necessary to repair the flame retardant coating by some means; the traditional repair method is Workers go down to the electric shaft, then drill into the underground tunnel, judge whether the coating on the surface of the cable is damaged by observation, and then repair it with a hand-held repair tool, and the cables in the underground tunnel are generally stacked together. When judging the coating on the surface of the cable, it is necessary to always lift the corresponding cable to facilitate observation of all the surfaces of the cable, which consumes a lot of physical strength for the worker, and it is inconvenient for the worker to observe the bottom of the cable; therefore, in summary, At present, there is a need in the market for a device that can reduce the workload of workers and accurately repair the damaged flame-retardant coating of cables

Embodiment Construction

[0022] The present invention can be explained in detail through the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0023] combined with Figure 1-2 The flame-retardant coating repair device for underground cables includes a slide cable 1, a sliding mechanism 2, a clamping mechanism 4 and a repair mechanism 5; the slide cable 1 is coaxially arranged in a tunnel, and the slide cable 1 There is a gap with the top surface of the tunnel. When the slide cable 1 is set, it first passes through the fixing frame 202 of the sliding mechanism 2, so that the pulley 201 is placed on the slide cable 1, and then the two ends of the slide cable 1 are fixed and installed respectively. On the wall of the electric well at both ends of the tunnel; the sliding mechanism 2 is correspondingly slidably connected with the slide rope 1, and the pulley 201 mechanism includes a pulley 201, a fix...

Abstract

The invention provides a flame-retardant coating repairing device for an underground cable. According to the flame-retardant coating repairing device, a repairing mechanism can be driven by a sliding mechanism to slide along a sliding rope, meanwhile, a cable can be clamped by a clamping mechanism, then a worker moves along with the sliding mechanism, and the worker controls the repairing mechanism to repair a damaged part by observing the damage condition of a flame-retardant coating on the surface of the cable. Therefore, the energy of workers is saved, the repairing efficiency is improved, and the repairing mechanism can accurately repair the flame-retardant coating.

Description

technical field [0001] The invention relates to the technical field of cable maintenance, in particular to a flame-retardant coating repair device for underground cables. Background technique [0002] It is well known that cables buried in underground tunnels, first, the flame retardant coating on the surface of the cable will be damaged due to bumps during laying, and second, oxidation-reduction reactions are prone to occur in humid environments, resulting in damage to the surface of the cable.
