The patent document discloses a solution of setting a steering traction component in the middle of multiple cable installation tubes to avoid the problem of dragging difficulties caused by excessive friction during cable laying. Specifically: the cable auxiliary installation device includes: a fixing mechanism, a first rotating seat, an adjustment plate, a driving assembly, a leading wheel and a traction mechanism; the fixing mechanism includes a mounting seat and a fastening assembly, the fastening assembly is arranged on the mounting seat, and the mounting seat is fixed in the corner well by the fastening assembly; the first rotating seat is arranged on the mounting seat; the adjustment plate and the first rotating seat are hinged; the driving assembly is arranged between the mounting seat and the adjustment plate, and the driving assembly is driven by the first rotating seat. The component adjusts the angle between the adjustment plate and the first rotating seat; the main wheel is rotatably arranged on the adjustment plate; the traction mechanism is arranged on the adjustment plate; during the cable installation process, the entire device is fixed in the corner well by the fixing component, and when the cable is passed through, when one end of the traction rope passes through the cable installation pipe, it then enters the next cable installation pipe after turning through the main wheel, and during the turning process, the traction mechanism can drag the cable in the corner well, which is more conducive to protecting the cable than the traditional installation mode. The traditional method forces the cable to turn when dragging the end of the cable, and after the cable is bent, it will be difficult to drag at the corner due to friction and change in force direction, and it is easy to damage the cable; However, when using the technical solution in the above patent document, it only has the function of guiding the cable from one cable installation duct to another cable installation duct, which is more suitable for use in short-distance cable installation situations.

[0039] The specific details of the cable auxiliary installation device using this application are as follows: 1. Preparation before use; First, put the cone-end pulling cylinder 41 on the end of the new cable 1-2, and adjust the position of the clamping arm 42 on the cone-end pulling cylinder 41 to achieve the clamping of the new cable 1-2; After that, the U-shaped head 51 is plugged into the traction groove 45 on the conical end traction cylinder 41, and the relative positions of the two are locked, the guide arm 52 is controlled to rotate relative to the U-shaped head 51, and the relative positions of the U-shaped head 51 and the guide arm 52 are locked, so that the U-shaped head 51 and the guide arm 52 are in a state of being ... Fig.10In the state of being perpendicular to each other, the guide arm 52 extends forward, and the handle II 54 is located at the end position of the guide arm 52 close to the U-shaped head 51 side.

[0040] 2. Use the cone-end pulling cylinder 41 to pull the new cable 1-2 and insert it between the multiple cable trays 11; First, hold the handle II 54 and pull the cone-end traction cylinder 41 to move toward the cable tray 11. Since the guide arm 52 extends forward, it can be inserted into the cable tray 11 before the cone-end traction cylinder 41, thereby achieving the purpose of guidance and auxiliary support and reducing hand pressure. After the end of the guide arm 52 passes through the cable tray 11, another set of handle II 54 and lateral telescopic arm 57 are replaced to clamp the front end of the guide arm 52. The clamping position is changed from Fig.10 The position is switched to Fig.11 The handle II 54 replaced later is located at the end of the guide arm 52 away from the U-shaped head 51; Finally, holding the replaced handle II 54, pull the cone-end traction cylinder 41 and the new cable 1-2 together, so that the cone-end traction cylinder 41 penetrates into the cable tray 11. During this process, the end traction cylinder 41 squeezes the old cable 1-1 in the cable tray 11 toward the inner edge of the cable tray 11, providing an installation position for the new cable 1-2, and completing the installation of the new cable 1-2 on the cable tray 11; repeat the above operation to realize the interlaced installation operation of the cable 1-2 between multiple cable trays 11.

[0041] 3. Use anti-scratch components to increase the smoothness of laying the new cable 1-2; Holding handle Ⅰ35, lift the anti-scratch assembly as a whole to the cable tray 11, and use the channel between the two plug posts 31 at the top and the elastic deformation characteristics of the arc-shaped leaf spring 32 to make multiple plug posts 31 sleeved on the outside of the new cable 1-2 and slide along the extension direction of the new cable 1-2; in this process, pull out and reinsert the handle Ⅰ35 on one side from the two plug posts 31 at the bottom to achieve smooth installation of the anti-scratch assembly in the cable tray 11; use the plug posts 31 and the arc-shaped leaf spring 32 to prevent the new cable 1-2 from directly contacting the old cable 1-1 in the cable tray 11 to avoid scratch damage to it, and use the roller 33 on the inside of the plug post 31 to rotate to increase the smoothness of laying the new cable 1-2.

[0043] In the above step 1, since the front end of the tapered end traction cylinder 41 is integrally formed with a tapered diameter reducing structure, the U-shaped head 51 and the guide arm 52 remain perpendicular to each other. Figure 2 As shown, when observed in the axial direction of the cone-end traction cylinder 41, the side position of the guide arm 52 still does not exceed the edge range of the cone-end traction cylinder 41, thereby effectively reducing the collision with facilities outside the installation area of ​​the new cable 1-2, avoiding unnecessary interference and damage to surrounding facilities, and ensuring the safety and stability of the entire system.

[0044] In the above step 2, since the diameter of the new cable 1-2 is limited, the diameter and length of the cone-end traction cylinder 41 do not need to be set too large. The proportions in the accompanying drawings are only used as a schematic diagram to clearly show the structure of each component, and are not the actual component size proportions.

The difference between this embodiment and the first embodiment is that: Figure 4 and Figure 8As shown, in this embodiment, the plug post 31 is made of iron-cobalt-nickel material, and a plurality of annular electromagnets 413 are provided at the end of the cone-end traction cylinder 41. The annular electromagnets 413 are connected to the plug post 31 through magnetic adsorption coupling; a docking inspection light 34 is provided at the end of the plug post 31, and a monitoring probe 412 for identifying the docking inspection light 34 is provided at the end of the cone-end traction cylinder 41.

[0054] By utilizing the magnetic attraction between multiple annular electromagnets 413 and multiple plugs 31, the cone-end traction cylinder 41 and the anti-scratch component can be stably docked, so that when the cone-end traction cylinder 41 penetrates the cable tray 11, the anti-scratch component at its rear end is inserted into the cable tray 11 together, thereby increasing the installation efficiency of the anti-scratch component.

[0055] Embodiment six: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, a docking seat 21 is detachably fixedly installed at the bottom of the cable tray 11, a sealing plate between the bottoms of the two cable trays 11 is plugged and slidably connected to the docking seat 21, and a plurality of C-shaped clips 22 for clamping the old cable 1-1 located at the bottom of the cable tray 11 are respectively arranged on both sides of the top of the docking seat 21, and a notch is reserved on the middle side of the top of the docking seat 21 for placing an anti-scratch component.

[0056] like Figure 2 As shown, a plurality of C-shaped clips 22 are used to clamp the old cable 1-1 at the bottom of the cable tray 11, so that when the new cable 1-2 is initially inserted into the cable tray 11 from the notch, the old cable 1-1 at the upper layer can be urged to arch upward without applying a horizontal squeezing force to the old cable 1-1 at the lower layer, so that this part of the old cable 1-1 at the lower layer and the corresponding old cable 1-1 on its upper side maintain a stable placement state, effectively avoiding serious interference with the layout of the old cable 1-1 due to the insertion of the new cable 1-2, thereby ensuring the stable operation of the cable system.

[0057] In order to keep the relative position of the anti-scratch assembly and the docking seat 21 stable, Figure 3 , Figure 5 and Figure 6 As shown, sockets 23 are fixedly installed on both sides of the bottom of the docking seat 21, and plugs 36 are fixedly installed on the side of the handle Ⅰ35. The plugs 36 on both sides are respectively inserted into the sockets 23 at the corresponding positions to limit the horizontal displacement of the anti-scratch component, so that the extension direction of the new cable 1-2 is consistent with the extension direction of the cable tray 11, thereby ensuring the smooth and stable laying of the cables.

[0058] Embodiment seven: The features common to the sixth embodiment are not described in detail. The differences between the sixth embodiment and the present embodiment are as follows: Figure 2 and Figure 5 As shown, in this embodiment, an elastic pad 13 is detachably fixedly installed between the two inner sides of the cable bridge 11, and sockets 12 for the elastic pad 13 to pass through are respectively provided at both ends of the cable bridge 11, and a fastener installation groove is provided on the cable bridge 11 above the socket 12, and the elastic pad 13 and the cable bridge 11 are detachably fixedly connected together by fasteners, and the lower side of the elastic pad 13 abuts against the outer side of the old cable 1-1.

[0059] like Figure 2 As shown, a pressure arm 14 is slidably installed on the lower top side of the cable bridge 11, and the bottom of the pressure arm 14 abuts against the upper side of the elastic pad 13. A tension spring 15 is installed between the cable bridge 11 and the pressure arm 14 to pull the pressure arm 14 to automatically extend downward; under the action of the tension spring 15, the pressure arm 14 is pulled toward the bottom direction of the cable bridge 11, so that the pressure arm 14 presses the upper side of the elastic pad 13, stretches and extends the elastic pad 13, and makes the lower side of the elastic pad 13 fully abut against the upper side of the multiple old cables 1-1 located on the upper layer, thereby limiting the movement of the cables in the cable bridge 11.

[0060] By combining the technical solutions of the sixth embodiment and the seventh embodiment, the cables can be stably placed inside the cable tray 11 .

[0061] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.

[0062] Except for the technical features described in the specification, the remaining technical features are known technologies to those skilled in the art. In order to highlight the innovative features of the present invention, the remaining technical features will not be described here in detail.
