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.

[0025] like Figure 1 As shown,

The inner walls of the transverse bridge 1 and the longitudinal bridge 2 are provided with a cable convenient arrangement mechanism 4.

[0027] In this implementation scheme: Under normal circumstances, the publication number "CN220341946U" discloses a cable bridge for use in underground pipe corridors, which is provided with a cable bridge body. By utilizing cable troughs at different positions arranged above the cable bridge body, the cables can be classified, placed and installed for the cable bridge, thereby avoiding too many cables in the underground pipe corridor being entangled together, making it inconvenient for the staff to check the cables later. Through the transparent plate, the staff can directly observe the cables inside the U-shaped cable bridge plate through the top of the U-shaped protective plate, thereby avoiding the staff from troubleshooting and checking faulty cables one by one, thereby improving the staff's maintenance and inspection efficiency of the cables. In actual use, when the cable passes through a bend, especially when the bend angle is large, if the inner diameter of the cable is too large, it is easy to be mechanically damaged during bending, such as friction, compression, etc. If the outer skin and internal structure of the cable are subjected to uneven force when the cable is bent, the internal conductor may be displaced, the insulation layer may crack, and even in extreme cases, there may be a risk of conductor breakage. By adding a convenient cable arrangement mechanism 4, when the bending angle of the bridge is too large, the cable can be conveniently laid at the large angle, and the cable at the bend can be protected at the same time, thereby ensuring the protection level of the cable and the flexibility of installation, and helping to maintain the stability and reliability of the cable system.

[0028] like Figure 1 - Figure 4 As shown,

[0029] Based on the existing cable trays used in underground pipe galleries, hoses can be connected to the bends of the cables to improve the protection performance of the cables, reduce stress concentration on the cables, and increase the flexibility and convenience of installation. This not only improves the protection level of the cables and the flexibility of installation, but also helps to maintain the stability and reliability of the cable system.

[0030] More specifically:

[0031] In combination with the above content, in order to facilitate the laying of cables at the place where the angle is too large when the bending angle of the bridge is too large, and at the same time to protect the cables at the bending place, thereby ensuring the protection level of the cables and the flexibility of installation, and also helping to maintain the stability and reliability of the cable system, the inner walls of the transverse bridge 1 and the longitudinal bridge 2 are provided with a cable convenient arrangement mechanism 4, the cable convenient arrangement mechanism 4 includes a conveying seat 41, a guide groove 42, a support side plate 43, a connecting component 44 and a positioning component 45, the conveying seat 41 is fixedly connected to the inner walls of the transverse bridge 1 and the longitudinal bridge 2, the guide grooves 42 are arranged side by side and equidistantly at the top of the conveying seat 41, the supporting side plates 43 are respectively installed on the end inner walls of the transverse bridge 1 and the longitudinal bridge 2, a connecting component 44 is provided between the two supporting side plates 43, and they are connected through the connecting component 44, and the positioning component 45 is arranged on the top of the conveying seat 41 and is located on the guide groove 42.

[0033] It should be noted that the top opening of the guide groove 42 described in this embodiment is smaller than the inner wall diameter of the guide groove 42, so that the end of the cable is inserted into the interior of the guide groove 42, which can effectively ensure that the cable is always inside the guide groove 42, thereby improving the convenience of installation.

[0034] In this embodiment: In order to ensure that the laying of cables is more efficient, the conveying seat 41 is fixedly connected to the inner walls of the transverse bridge 1 and the longitudinal bridge 2, and the guide grooves 42 are opened side by side and equidistantly at the top of the conveying seat 41.

The end of the soft flexible tube 442 is screwed to the end of the threaded sleeve 441 through the threaded head 443.

[0036] In this embodiment: In order to ensure the protective effect of the cable at a larger bending angle, the threaded sleeve 441 penetrates the side wall of the supporting side plate 43 in parallel and equidistantly, and the threaded sleeve 441 corresponds to the guide groove 42 one by one, the inner diameter of the threaded sleeve 441 is the same as the inner diameter of the guide groove 42, and the threaded head 443 is fixedly connected to the two ends of the soft flexible tube 442, and the end of the soft flexible tube 442 is screwed to the end of the threaded sleeve 441 through the threaded head 443, and then the cable is passed through the soft flexible tube 442, and then the two ends of the soft flexible tube 442 are installed in the threaded sleeve 441 through the threaded head 443, thereby improving the protection performance of the cable, reducing the stress concentration of the cable, and increasing the flexibility and convenience of installation, which not only improves the protection level of the cable and the flexibility of installation, but also helps to maintain the stability and reliability of the cable system.

[0037] To be more specific: the positioning assembly 45 includes a sliding sleeve 451, a positioning sleeve 452, an adjusting screw 453, a mounting plate 454 and a pressure pad 455. The sliding sleeve 451 is slidably mounted on the top of the conveying seat 41 and is located on the guide groove 42. The positioning sleeve 452 is fixedly passed through the top of the sliding sleeve 451. One end of the adjusting screw 453 is threadedly passed through the positioning sleeve 452 and is rotatably connected to the top of the mounting plate 454. The pressure pad 455 is fixedly connected to the bottom of the mounting plate 454.

[0038] Furthermore, if Figure 1 As shown, the bottom of both ends of the sliding sleeve 451 are symmetrically fixed with clamping plates, and the top of the conveying seat 41 is symmetrically provided with sliding grooves matching the clamping plates on both sides of the guide groove 42, and the lower pressure pad 455 is a soft rubber pad.

[0039] In this embodiment: In order to further ensure that the cable is more stable during laying, the sliding sleeve 451 is slidably installed on the top of the conveying seat 41 and is located on the guide groove 42. The positioning sleeve 452 is fixedly passed through the top of the sliding sleeve 451. One end of the adjusting screw rod 453 is threadedly passed through the positioning sleeve 452 and is rotatably connected to the top of the mounting plate 454.
