In addition, the blades 11 preferably cut the tubular body 2 with a line of cut which is offset from the radial axis of the section of the tubular body 2, so as to avoid cutting the optical cable.

It should be noted that a slide groove may be formed in the base plate 3, a screw hole may be formed in a connecting portion between the guide portion 4 and the base plate 3, and the guide portion 4 may be fixed to the base plate 3 by fastening bolts passing through the slide groove and the screw hole, so that the guide portion 4 may move relative to the base plate 3. Preferably, the guide portion 4 moves relative to the base plate 3 in a direction perpendicular to the direction in which the tubular body 2 extends. In addition, the end of the guiding portion 4 extending outward away from the substrate 3 can be bent toward one side of the tube 2, so that the surface of the guiding portion 4 is attached to the outer wall of the tube 2 more tightly.

The positioning portion 5 is arranged on the end face of the base plate 3 far away from the side of the tube body 2, the cutting machine 1 is arranged on the positioning portion 5, the blade 11 penetrates through the window 301 and cuts the tube body 2, the positioning portion 5 can selectively move relative to the base plate 3 and adjust the area of the blade 11, which penetrates through the window 301 and is located on the side where the base plate 3 abuts against the steel tube, so that the cutting depth of the blade 11 for cutting the tube body 2 is adjusted, and the larger the area of the blade 11 located on the side where the base plate 3 abuts against the steel tube is, the deeper the cutting depth is, and vice versa.

In a second aspect, the invention further provides an optical cable guide tube modification method, which utilizes the device for optical cable guide tube modification to modify an optical cable guide tube, and comprises the following steps.

Step one, because the pipe body 2 is a steel pipe in the traditional mode and is connected to a machine room in an L-shaped underground laying mode, the underground part of the pipe body 2 is arranged in a backfill trench and is filled with earth, and the overground part is arranged on a framework column of a transformer substation; therefore, when the steel pipe is modified, the earthwork needs to be excavated first, so that the part of the steel pipe body 2 to be replaced, which is laid underground, is exposed.

Step two, in order to achieve the purposes of preventing water, dust, organisms and the like, the pipe body 2 is provided with end part plugging mechanisms such as a half sealing device and the like at two ends of the pipe body 2; therefore, before the modification, it is necessary to remove the end plugs at the two ends of the tube body 2, and determine the cutting position and the cutting depth of the blade 11 of the device for modifying the optical cable guide tube according to the tube diameter of the tube body 2.

Specifically, the cutting position of the blade 11 for cutting the pipe body 2 is determined by adjusting the distance between the part of the guide part 4, which is abutted against the outer wall of the pipe body 2, and the window 301; the cutting depth of the blade 11 cutting the tube body 2 is determined by adjusting the size of the area of the blade 11 passing through the window 301 and located on the side of the substrate 3 abutting against the tube body 2.

Step three, the movable cutting machine 1 cuts the tube body 2, after a first cutting groove 201 is cut on the tube body 2 by the blade 11 along the extending direction of the tube body 2, the tube body 2 is rotated, and a second cutting groove 202 is cut on the tube body 2 by the blade 11 along the direction parallel to the first cutting groove 201; since both ends of the first cutting groove 201 and the second cutting groove 202 penetrate both ends of the tube body 2, a portion of the tube body 2 between the first cutting groove 201 and the second cutting groove 202, which is cut off, can be taken off from the tube body 2, so that a space is formed between the first cutting groove 201 and the second cutting groove 202, the optical cable can be pulled out from the space, and the steel tube body 2 can be taken off. Wherein the first cut groove 201 and the second cut groove 202 are preferably spaced apart by a width greater than the diameter of the cable so that the cable can be removed.

And fourthly, penetrating the optical cable into a new replacement pipe 6, arranging end plugs at two ends of the replacement pipe 6 so as to finish the replacement of the pipe body 2, and then filling the part for underground laying in the replacement pipe 6 with earth, namely finishing the reconstruction of the guide pipe.

The invention also designs another embodiment which can better protect the optical cable when the tube body 2 is cut.

Particularly, in step three, still including being used for preventing the protection tube 7 of cutting, before cutting, insert body 2 with protection tube 7 from the tip of body 2 earlier in to the cover is established outside the optical cable in waiting to cut section's body 2, protection tube 7 sets up with 2 inner walls of body intervals, thereby plays the effect of protection to the optical cable, only can avoid blade 11 to cut off the optical cable, also can avoid the high temperature splash that blade 11 cutting body 2 produced to lead to the fact harmful effects to the optical cable.

Meanwhile, in order to realize the reconstruction of the traditional steel tube guide tube, the invention also designs a novel guide tube structure which is more convenient to install and replace, and simultaneously does not need to disconnect the optical cable and suspend the optical cable service during disassembly, assembly and maintenance, thereby being adapted to the reconstruction method of the invention.

As shown in fig. 1 and with reference to fig. 5, in step four, the replacement pipe 6 includes a plurality of pipe units 61 connected end to end in sequence, so that when one or more pipe units 61 assembled to form the replacement pipe 6 are damaged, only the damaged pipe unit 61 needs to be replaced, thereby greatly reducing the modification cost.

At the same time, the invention also envisages another embodiment of the replacement tube 6.

As shown in fig. 1 and fig. 6, the tube unit 61 includes a first half tube 611 and a second half tube 612, and edges of the first half tube 611 and the second half tube 612 along the extending direction are buckled with each other and enclose the tube unit 61, so that the tube unit 61 is conveniently sleeved on the optical cable without disconnecting the optical cable, and the operation difficulty of modifying the guide tube is greatly reduced. It should be noted that, even though replacement tube 6 is not assembled by a plurality of tube units 61, replacement tube 6 of a single tube is also suitable for the structure of first half tube 611 and second half tube 612, so as to be conveniently sleeved outside the optical cable.

On the basis, the guide tube is modified in the fourth step, and when the replacement tube 6 is arranged on the optical cable, as shown in fig. 1, with reference to fig. 4, the outer surface of the guide optical cable is cleaned, then the guide optical cable is arranged in the first half tube 611, and the second half tube 612 is fastened on the first half tube 611, so that the guide optical cable is inserted into the tube unit 61, then the tube units 61 are sequentially connected end to form the replacement tube 6, the adjacent tube units 61 are tightly clamped and fixed by the stainless steel hose clamp, and the connection gaps are sealed by coating sealant.

Further, since the guide pipe includes an above-ground laying portion and an below-ground laying portion, in order to fit the size of the backfill trench, it is preferable that in step four, when installing the replacement pipe 6, the pipe units 61 are arranged in order from the portion where the replacement pipe 6 is located below-ground laying to the portion where the replacement pipe 6 is located above-ground laying.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
