[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 2-Figure 3 The utility model provides an embodiment of a fireproof trough type bridge that can reduce cable wear, including a trough body 1, which can support the lower sleeve 3 to keep it relatively fixed, and a closing component is slidably connected to the upper side end of the trough body 1, which can close the upper end of the overall device, and the lower sleeve 3 is fixedly connected to the inside of the trough body 1. The lower sleeve 3 and the upper sleeve 2 are semicircular and can clamp the cable. The two side ends of the lower sleeve 3 are fixedly connected to the upper sleeve 2 by bolts 8. The upper sleeve 2 can cooperate with the lower sleeve 3 to clamp and close the cable so that it is placed neatly and will not cause wear and tear due to friction with the trough body 1. The outer sides of the bolts 8 are respectively threadedly connected to the insides of the two sides of the upper sleeve 2 and the lower sleeve 3. The bolts 8 keep the upper sleeve 2 and the lower sleeve 3 relatively fixed, and the lower sleeve 3 is rotatably connected to the inside of the rotating shaft 7. The rotation of the rotating shaft 7 can reduce the wear caused by friction with the lower sleeve 3 during cable installation.

[0033] Reference Figure 3-Figure 5The middle inner part of the upper sleeve 2 is slidably connected with a sliding block 9, and the sliding block 9 can drive the extrusion plate 10 to slide vertically and be fixed. The lower part of the sliding block 9 is fixedly connected with the extrusion plate 10, and the extrusion plate 10 is arc-shaped, which can clamp the cable so that the cable can remain relatively fixed when the slot body 1 shakes, and will not shake. The lower part of the extrusion plate 10 is slidably connected to the interior of the upper sleeve 2 and the lower sleeve 3, and the middle inner part of the upper sleeve 2 is elastically connected with a clamping block 12 through a spring 11. The clamping block 12 is L-shaped, and the short side of the upper end passes through the upper part of the upper sleeve 2, which is convenient for the clamping block 12 to slide out. The lower part of the clamping block 12 is slidably connected to the inside of the side end of the sliding block 9. The clamping block 12 slides into the inside of the sliding block 9 to keep the sliding block 9 fixed and no longer slide. One end of the spring 11 is fixedly connected to the middle inner part of the upper sleeve 2 The spring 11 is squeezed by the upper sleeve 2 to keep the squeezed clamping block 12 so that its lower part slides out. The other end of the spring 11 is fixedly connected to the outside of the side end of the clamping block 12. An I-shaped block 13 is slidably connected to the right inner wall of the sliding block 9. The I-shaped block 13 drives the inclined surface block 14 to slide vertically within a fixed distance relative to the sliding block 9, so as to prevent it from blocking the sliding of the sliding block 9. The two ends of the I-shaped block 13 are fixedly connected with inclined surface blocks 14. The I-shaped block 13 can slide horizontally inside the sliding block 9, so as to drive the inclined surface blocks 14 at both ends to slide and squeeze the clamping block 12 to slide out of the sliding block 9 at the same time, and release the limit. The left part of the inclined surface block 14 contacts the upper part of the clamping block 12. The left end of the inclined surface block 14 is a slope, which can squeeze the upper end of the clamping block 12 and drive the clamping block 12 to slide out of the sliding block 9.

[0034] Reference Figure 1-Figure 2 The closing assembly includes an end cover 4, which can close the upper end of the trough body 1, and the lower part of the end cover 4 is slidably connected to the outer part of the upper end of the trough body 1. The outer parts of the two side ends of the end cover 4 are elastically connected with a clamping rod 5 through a spring 26. The clamping rod 5 is U-shaped, and the lower parts of the two ends are arc surfaces, which are convenient for the clamping rod 5 to slide to both ends when the end cover 4 slides down without blocking the end cover 4. The outer part of the clamping rod 5 is slidably connected to the inner part of the two ends of the end cover 4, and the end cover 4 keeps the clamping rod 5 from sliding horizontally. One end of the spring 26 is fixedly connected to the middle outer part of the clamping rod 5, and the other end of the spring 26 is fixedly connected to the outer part of the side end of the end cover 4. The spring 26 is subjected to the pulling force of the end cover 4 so that the clamping rod 5 can be pulled into the interior of the trough body 1 and remain fixed, which can facilitate the installation and removal of the end cover 4.

[0035] Working principle: Place the cable on the upper part of the rotating shaft 7, then pull the cable to pass through the lower sleeve 3, then place the upper sleeve 2 on the upper part of the lower sleeve 3, fix the upper sleeve 2 and the lower sleeve 3 with the bolt 8, then press the I-shaped block 13, the I-shaped block 13 drives the inclined block 14 to slide horizontally, the inclined block 14 slides horizontally to squeeze the upper part of the clamping block 12, the clamping block 12 slides out of the internal compression spring 11 at both ends of the sliding block 9, slide the sliding block 9 downward, and the sliding block 9 drives the extrusion plate 10 to slide downward Until the lower part of the extrusion plate 10 contacts the upper part of the cable, the I-block 13 is released, and the spring 11 squeezes the clamping block 12 to slide into the two ends of the sliding block 9. The clamping block 12 squeezes the inclined block 14 to drive the I-block 13 to slide back to its original position, and then the end cover 4 is slid to the upper part of the slot body 1, and the upper part of the slot body 1 squeezes the clamping rod 5 to slide to both ends to pull the spring 2 6. When the end cover 4 slides to the point where it can no longer slide, the clamping rod 5 slides into the two ends of the slot body 1 under the pulling force of the spring 2 6, keeping the end cover 4 and the slot body 1 relatively fixed.
