Description

Technical Field

[0001] The invention relates to the technical field of cable laying, and in particular to a method for laying cables in a bridge frame of an overhead pipe network. Background Art

[0002] At present, the factory area is usually composed of multiple areas with different functions, such as production area, storage area, office area, living area, etc. The external network cable can connect the power system and communication system of these areas to realize the power distribution and signal interaction between the areas. Various production machines and equipment in the factory area, such as large machine tools, production lines, cranes, etc., require a stable power supply to operate normally. The external network cable is like an "electric artery", transmitting the power from the substation or the main distribution room to the distribution box or control cabinet near these equipment to provide power for production activities.

[0003] The laying of cables for the external network of the factory area is usually mainly done by laying cables in the bridge frame on the overhead pipe network, laying cables directly buried, and laying cables in the cable trench. Among these three laying methods, the construction organization and technical difficulty of laying cables in the bridge frame on the overhead pipe network are the most complicated.

[0004] At present, the common practice is to pull the cable to the overhead pipe network platform, and arrange enough personnel on the platform to place the cable section by section at the bottom of the bridge or the specified layered position. For the laying of multiple cables, they should be arranged in layers according to the design requirements. The disadvantage of this method is that it requires more manpower and the high-altitude operation is more dangerous.

[0050] Continue to refer to Figure 3 and Figure 4 In this embodiment, the cable slide 3 includes a plurality of slide units 31, and the plurality of slide units 31 are detachably connected in sequence along the cable laying direction; such a configuration increases the application scope of the cable slide 3.

[0051] Among them, the slide unit 31 includes a shell 311, a cover plate 312, a fixed plate 313 and a plurality of gears 314. The cover plate 312 is covered on the shell 311, and the cover plate 312 is rotatably connected to the shell 311. The shell 311 is enclosed to form a cavity, and the cavity is divided into a first cavity and a second cavity. The first cavity is connected to the second cavity, and the first cavity and the second cavity are arranged in sequence from top to bottom. A plurality of gears 314 are arranged in the second cavity, and the plurality of gears 314 are arranged at intervals along the extension direction of the second cavity, and the plurality of gears 314 can rotate relative to the shell 311; the fixed plate 313 is arranged at the bottom end of the shell 311, and the fixed plate 313 is fastened to the steel purlin 10 of the overhead pipe network 1 through a locking member 315.

[0052] Specifically, the cover plate 312 is rotatably connected to the housing 311 via a hinge. The first cavity is used to place the slider 5 wrapped on the outer peripheral wall of the cable 8 to be laid, and the slider 5 can slide along the first cavity.

[0053] When there is no branching or turning of the overhead pipe network 1, a plurality of first cavities are connected in sequence to form a slide cavity, and a plurality of second cavities are connected in sequence to form a gear cavity.

[0054] Continue to refer to Figure 6 In this embodiment, the slider 5 includes a first block 51 and a second block 52. The first block 51 is provided with a first arc-shaped through groove, and the second block 52 is provided with a second arc-shaped through groove. The side of the second block 52 provided with the second arc-shaped through groove is in contact with the side of the first block 51 provided with the first arc-shaped through groove. The first block 51 is rotatably connected to the second block 52 through a hinge. The first arc-shaped through groove and the second arc-shaped through groove are correspondingly arranged. The first arc-shaped through groove and the second arc-shaped through groove together constitute a rotating through cavity 54. An anti-slip layer is adhered to the inner circumferential wall of the rotating cavity, and the cable 8 to be laid is passed through the rotating through cavity 54. , the outer peripheral wall of the cable 8 to be laid is in contact with the anti-skid layer; the bottom ends of the first block 51 and the second block 52 are both provided with a rack 53 meshing with the gear 314; on the one hand, by providing the rack 53, the friction is reduced during the sliding process of the slider 5, and the energy loss can be reduced with a higher transmission efficiency, so as to achieve the purpose of fast and labor-saving laying of cables on the high-altitude pipe rack; on the other hand, by providing the anti-skid layer, the cable 8 to be laid can be firmly fixed to prevent slipping during the traction process of the cable 8 to be laid, and the outer skin of the cable 8 to be laid can be protected to prevent the slider 5 from damaging the outer skin of the cable 8 to be laid.

[0055] It should be noted that the structures of the first block 51 and the second block 52 may be the same or different. In this embodiment, the structures of the first block 51 and the second block 52 are substantially the same.

[0056] During use, the second block 52 is opened, the cable 8 to be laid is inserted into the first arc-shaped through groove, and then the second block 52 is covered so that the slider 5 is wrapped around the outer peripheral wall of the cable 8 to be laid. When the slider 5 is inside the slide cavity, the slider 5 is in close contact with the slide cavity wall so that the slider 5 remains in a closed state and moves forward with the pulling force of the traction rope. When the slider 5 leaves the slide cavity, the slider 5 falls off from the cable 8 to be laid due to gravity and falls at the exit of the slide cavity.

[0057] It should be noted that the rotating through cavity 54 can be manufactured in various specifications according to the outer diameter of common cables.
