[0035] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0036] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, mechanical or electrical connections, direct or indirect connections through an intermediate medium, and internal communication between two elements or interaction between two elements. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] In the description of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] like Figures 1-6As shown, the present invention provides a cable laying auxiliary device, including a bracket 1, a bottom roller 2, a first side roller 3 and a second side roller 4. The bottom roller 2 is rotatably connected to the bracket 1, and the bottom roller 2 can rotate around a horizontal axis. The first side roller 3 is rotatably connected to the bracket 1, and the first side roller 3 can rotate around a vertical axis. The second side roller 4 is rotatably connected to the bracket 1, and the second side roller 4 can rotate around a vertical axis. The bottom roller 2, the first side roller 3 and the second side roller 4 rotate along a first direction ( Figure 3 In the X direction, when in use, the first direction can be a direction parallel to the axial direction of the cable) staggered setting, that is, a limiting action area for the cable 100 is formed in the first direction, the first direction is perpendicular to both the horizontal axis and the vertical axis, the first side roller 3 and the second side roller 4 are located on both sides of the axial direction of the bottom roller 2, and as shown Figure 1 As shown, the orthographic projections of the contour lines of the bottom roller 2 , the first side roller 3 and the second side roller 4 in the vertical plane perpendicular to the first direction form a continuous closed path.

[0040] During the laying of cable 100, bottom roller 2 primarily bears and guides the cable 100, while first side roller 3 and second side roller 4 provide lateral positioning and guidance for the cable 100. The bottom roller 2, first side roller 3, and second side roller 4 are staggered along a first direction, extending the area within which the cable-laying auxiliary device limits the cable 100. This enhances the guiding effect on the cable 100 while preventing the cable 100 from escaping from the device during the laying process. The projections of the contours of bottom roller 2, first side roller 3, and second side roller 4 onto a vertical plane perpendicular to the first direction form a continuous closed path, creating a circumferentially closed positioning space for the cable 100. This further locks the cable 100 in place, preventing it from escaping from the device during the laying process and damaging the cable sheath.

[0041] Specifically, if Figure 2 As shown, the first side roller 3 is a single-sided flared roller, including a first cylindrical section 31 and a first flared section 32 connected to each other, and the first flared section 32 is located above the first cylindrical section 31. The second side roller 4 is a single-sided flared roller, including a second cylindrical section 41 and a second flared section 42 connected to each other, and the second flared section 42 is located above the second cylindrical section 41. Figure 1As shown, the projections of the contours of the first side roller 3 and the second side roller 4 in a vertical plane perpendicular to the first direction are symmetrical relative to the center line of the bracket 1. The first side roller 3 and the second side roller 4 are single-sided flared rollers, so that the upper part of the circumferential closed limiting space formed by the bottom roller 2, the first side roller 3 and the second side roller 4 for the cable 100 is an arc-shaped structure, which can fit the circular cross-section of the cable 100, increase the accommodation capacity of the circumferential closed limiting space, make the cable laying auxiliary device suitable for cables 100 with larger diameters, and improve the versatility of the cable laying auxiliary device. The projections of the contours of the first side roller 3 and the second side roller 4 in a vertical plane perpendicular to the first direction are symmetrical, which can naturally guide the cable 100 to the center position and prevent the cable 100 from deviating or falling out, and is particularly suitable for inclined or curved laying scenarios.

[0042] Alternatively, as Figure 4 and Figure 5 As shown, the bracket 1 is provided with a first connection part 11 and a second connection part 12 on opposite sides along the first direction. In this embodiment, the first connection part 11 is a raised structure composed of a rectangular block and a cylinder, and the second connection part 12 is a groove that cooperates with the first connection part 11. The first connection part 11 can be snapped into the second connection part 12, and the two cable laying auxiliary devices can be spliced ​​through the first connection part 11 and the second connection part 12 to achieve modular connection between the cable laying auxiliary devices. By splicing two or more cable laying auxiliary devices together, the limiting action area of ​​the circumferential closed limiting space formed by the cable laying auxiliary device for the cable 100 is further lengthened, so that the cable laying auxiliary device can adapt to the laying requirements of different lengths or complex paths. In other embodiments, the first connection part 11 and the second connection part 12 can also be plugs and slots, which are not specifically limited here.

[0043] Furthermore, if Figure 2As shown, the bracket 1 includes a bottom frame 13 and mounting shafts 14. The bottom frame 13 is a stepped frame with a larger bottom area than its top area. At least two mounting shafts 14 are vertically mounted on the bottom frame 13, with the first side roller 3 and the second side roller 4 each rotatably connected to one mounting shaft 14. Specifically, the two mounting shafts 14 are staggered along a first direction on either side of the bottom frame 13. The first side roller 3 is rotatably connected to one mounting shaft 14 via two bearings, and the second side roller 4 is rotatably connected to one mounting shaft 14 via two bearings. Limiting members are provided at the upper and lower ends of the mounting shafts 14 to prevent the first and second side rollers 3 and 4 from dislodging from the mounting shafts 14. The bottom roller 2 is rotatably connected to the bottom frame 13 via a horizontal mounting shaft. The horizontal mounting shaft and the two mounting shafts 14 are staggered in the first direction. The stepped bottom frame 13 effectively lowers the overall center of gravity of the cable laying auxiliary device, preventing it from tipping over. The mounting shaft 14 vertically arranged on the bottom frame 13 simplifies the layout of the first side roller 3 and the second side roller 4 , ensuring that the first side roller 3 and the second side roller 4 are subjected to balanced forces.

[0044] Exemplarily, the bracket 1 further includes a sliding connector that is slidably connected to the bottom frame 13. Each mounting shaft 14 is vertically fixedly connected to a sliding connector. Each sliding connector can slide on the bottom frame 13 along the horizontal axial direction, so that the first side roller 3 and the second side roller 4 move toward or away from the bottom roller 2 along the horizontal axis. The first side roller 3 and the second side roller 4 are indirectly connected to the bracket 1 via the sliding connector and can slide along the horizontal axis driven by the sliding connector to adjust the size of the circumferential closed confining space formed by the cable 100. When the first side roller 3 or the second side roller 4 moves away from the bottom roller 2 along the horizontal axis, the upper portion of the circumferential closed confining space opens, facilitating the installation of the cable 100 within the circumferential closed confining space. Specifically, two sliding grooves extending along the horizontal axis are provided on the bottom frame 13, and the sliding connection is a slider. A slider is slidably connected in each of the two sliding grooves, and a mounting shaft 14 is vertically fixedly connected to a slider. The first side roller 3 is rotatably connected to a mounting shaft 14 through two bearings, and the second side roller 4 is rotatably connected to a mounting shaft 14 through two bearings.

[0045] In this embodiment, the bottom roller 2 is a cylindrical roller. Cylindrical rollers have a simple structure and low manufacturing cost, making them suitable for laying cables 100 along a straight path. In other embodiments, the bottom roller 2 can also be a double-tapered roller, comprising a central cylindrical section and conical guide sections symmetrically arranged along the central cylindrical section, with the central cylindrical section and the conical guide sections coaxially arranged. The conical guide sections automatically center the cable 100, preventing it from drifting or falling out, while the central cylindrical section distributes pressure on the cable 100.

[0046] Optionally, the bracket 1 is further provided with a drive mechanism configured to drive the bottom roller 2 to rotate about a horizontal axis. By actively driving the bottom roller 2, the drive mechanism reduces the resistance to manual pulling of the cable 100, making it particularly suitable for laying long-distance or heavy cables 100. The drive mechanism can be an electric motor or a pneumatic motor, which is not specifically limited here.

[0047] Furthermore, the surface of the bottom roller 2 is coated with an elastic layer, and a plurality of annular pressure relief grooves are formed on the outer circumference of the elastic layer. The elastic layer can buffer the rigid contact between the cable 100 and the bottom roller 2, while the annular pressure relief grooves can further relieve the extrusion stress, thereby preventing damage to the outer sheath of the cable 100 during the laying process.

[0048] Optionally, a plurality of lockable universal wheels are symmetrically provided at the bottom of the bracket 1. The lockable universal wheels facilitate the flexible movement and positioning of the cable laying auxiliary device during use. When locked, they ensure the stability of the cable laying auxiliary device during cable laying, making it more suitable for complex terrain on the construction site.

[0049] On the other hand, the present invention also provides an operating method for a cable laying auxiliary device, which uses the above-mentioned cable laying auxiliary device to assist in supporting the cable 100, including the following steps: S1, horizontally rotating the cable laying auxiliary device by a certain angle, and overlapping the cable 100 on the bottom roller 2; S2, horizontally rotating the cable laying auxiliary device in the opposite direction to step S1, so that the cable 100 is in a continuous closed path; S3, adjusting the direction of the cable 100 so that the length direction of the cable 100 is parallel to the first direction.

[0050] Specifically, if Figure 6 As shown, the cable laying auxiliary device is horizontally rotated a certain angle to increase the spacing between the first side roller 3 and the second side roller 4 in a direction perpendicular to the length direction of the cable 100 in the horizontal plane, allowing the cable 100 to easily overlap the bottom roller 2 without interference from the first side roller 3 and the second side roller 4. At this time, the length direction of the cable 100 forms a certain angle with the horizontal axis in the horizontal plane. Further, the cable laying auxiliary device is horizontally rotated in the opposite direction to that in step S1, returning the cable laying auxiliary device to its initial position. At this time, the cable 100 is located within a continuous closed path formed by the contours of the bottom roller 2, the first side roller 3, and the second side roller 4 projected into a vertical plane perpendicular to the first direction, thereby forming a circumferential limit for the cable 100. Furthermore, the direction of the cable 100 is adjusted so that the length direction of the cable 100 is parallel to the first direction to prevent the cable 100 from deviating or falling out of the cable laying auxiliary device during the laying process.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
