Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying frame for auxiliary cable laying. Background Technology
[0002] Cable laying often requires extending or maintaining underground lines through manholes. Traditional laying methods mainly rely on manual cable pulling or the use of simple supports to temporarily fix the cable direction. Ordinary supports are mostly fixed structures and cannot adjust the cable guiding angle according to the actual laying path, which makes the cable prone to bending or tangling at the manhole, increasing the difficulty of construction and the risk of cable damage. Moreover, the cable is prone to displacement due to loosening during the pulling process, affecting construction safety. The cable needs to be dragged during laying, and the friction between the cable and the support surface is large, which not only consumes manpower but may also cause wear on the cable sheath and shorten its service life.
[0003] Therefore, it is necessary to provide a new cable laying frame for auxiliary cable laying to solve the above-mentioned technical problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] Please refer to the following: Figures 1-6 ,in, Figure 1 A three-dimensional structural diagram of the cable laying frame for auxiliary cable laying provided by this utility model; Figure 2 Exploded view of the cable laying frame for auxiliary cable laying provided by this utility model; Figure 3 Partial structural diagram provided by this utility model Figure 1 ; Figure 4 Partial structural diagram provided by this utility model Figure 2 ; Figure 5 Provided by this utility model Figure 4 Enlarged structural diagram at point B; Figure 6 Provided by this utility model Figure 3 Enlarged structural diagram at point A in the middle.
[0027] In the specific implementation process, such as Figures 1-6 As shown, an auxiliary cable laying frame is used to provide guidance and support for cable laying at the manhole opening, including a support plate 1, a top cover 3, a rotating seat 4, a guide seat 6, a rotating mechanism, and a support mechanism.
[0028] The support plate 1 is a rectangular metal plate with a mounting groove 2 in the middle. The top cover 3 is fixed to the inner side of the top of the mounting groove 2 to form a closed cavity.
[0029] The rotating seat 4 has a cylindrical structure with a through hole 5 in the middle for the cable to pass through. Its outer circumference is rotatably connected to the side wall of the mounting groove 2 via bearings, enabling horizontal rotation. A guide seat 6 is fixed at the top and bottom of the rotating seat 4. Each guide seat 6 includes a bracket 7 and a guide roller 8: the bracket 7 is fixed to the rotating seat 4 by welding, and the guide roller 8 is rotatably connected to the U-shaped groove of the bracket 7 via bearings to guide the cable and reduce friction during cable laying.
[0030] The rotating mechanism is used to drive the rotating base 4 to rotate, and includes:
[0031] First worm gear 11: Rotatably connected to the side wall of support plate 1 via bearing, its axis is perpendicular to the axis of rotating seat 4;
[0032] First knob 9: Fixed to the outer end of the first worm gear 11, used for manual operation;
[0033] Rotating shaft 12: Rotatably connected to the bottom of top cover 3 via bearing;
[0034] First worm gear 10: Fixed in the middle of the rotating shaft 12, meshing with the first worm 11 to achieve speed reduction transmission;
[0035] Driven gear 13 and driven gear 14: Driven gear 13 meshes with driven gear 14 on the outside of rotating seat 4, transmitting the rotation of rotating shaft 12 to rotating seat 4.
[0036] During operation, rotating the first knob 9 drives the rotating shaft 12 to rotate via the worm gear transmission, which in turn drives the rotating seat 4 to rotate via the gear transmission, thus adjusting the angle of the guide seat 6.
[0037] The support mechanism is used to fix the laying frame at the manhole opening, and includes:
[0038] The second worm gear 17 is rotatably connected to the side wall of the support plate 1 via a bearing, and its axis is perpendicular to the axis of the lead screw 18.
[0039] Second knob 15: Fixed to the outer end of the second worm gear 17, used for manual operation;
[0040] Second worm gear 16: Fixed in the middle of lead screw 18, meshing with second worm 17 to achieve self-locking function;
[0041] Lead screw 18: The threads at both ends turn in opposite directions and connect to two sets of support components respectively;
[0042] Support assembly: Each assembly includes an arc plate 19, a guide rod 20, and a casing 21. The inner side of the arc plate 19 is attached to the inner wall of the manhole opening, the guide rod 20 and the casing 21 are slidably connected in the guide groove of the support plate 1, and the casing 21 is threadedly connected to the lead screw 18.
[0043] During operation, rotating the second knob 15 drives the lead screw 18 to rotate via the worm gear transmission, causing the two sets of support components to move outward synchronously, and the arc plate 19 to be tightly attached to the inner wall of the manhole opening for fixation.
[0044] The working principle of the cable laying frame for auxiliary cable laying provided by this utility model is as follows: The laying frame is placed above the manhole opening. Rotating the second knob 15 expands the arc-shaped plate 19 through the support mechanism, causing it to press against the inner wall of the manhole opening, thus completing the fixation. According to the cable laying direction, rotating the first knob 9 drives the rotating seat 4 to rotate through the rotating mechanism, adjusting the angle of the guide seat 6 so that the guiding direction of the guide roller 8 is consistent with the laying path. The cable is passed through the through hole 5 of the rotating seat 4 and placed in the V-groove of the guide roller 8. When the cable is pushed, the guide roller 8 moves freely with the cable, reducing frictional resistance.
[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
