[0038] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.
[0039] Combination Figures 1 to 10 As shown, this embodiment is a cable laying device, including a support assembly, a rotating shaft fixing bracket 2, a cable rotating shaft 1 and a rotating adjustment assembly 3. The cable rotating shaft 1 is rotatably connected to the rotating shaft fixing bracket 2. The cable rotating shaft 1 is arranged horizontally and can wind the cable. The rotating shaft fixing bracket 2 is connected to the support assembly via the rotating adjustment assembly 3. The top of the rotating adjustment assembly 3 is rotatably connected to the bottom of the rotating shaft fixing bracket 2. The bottom of the rotating adjustment assembly 3 is rotatably connected to the top of the support assembly. The rotating adjustment assembly 3 is used to enable the rotating shaft fixing bracket 2 to rotate circumferentially around the axis of the rotating adjustment assembly 3.
[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the support assembly includes a chassis bracket 4 and a plurality of fixed legs 5, the top of the chassis bracket 4 is rotatably connected to the rotation adjustment assembly 3, and the bottom of the chassis bracket 4 is connected to a plurality of fixed legs 5. Specifically, four fixed legs 5 are used in this embodiment, and the fixed legs 5 are angle steel legs, which are convenient for inserting into the soil to achieve fixation during outdoor cable laying operations, and can reduce the risk of damage to the device caused by external force of cable pulling. The chassis bracket 4 is made of a steel plate made of solid flat galvanized steel, and the material should have anti-corrosion function and high hardness requirements.
[0041] In some embodiments, such as Figure 3 and Figure 4 As shown, the rotation adjustment component 3 has a double bearing structure, and the rotation adjustment component 3 includes a connecting block 7 and a first bearing 6. In this embodiment, the connecting block 7 is made of ordinary bright galvanized steel, and the first bearing 6 is welded to the top and bottom of the connecting block 7. The top of the connecting block 7 is connected to the bottom of the rotating shaft fixing bracket 2 through the first bearing 6, and the bottom of the connecting block 7 is connected to the chassis bracket 4 through the first bearing 6.
[0042] Further, such as Figure 5 As shown, a solid connecting rod 9 is welded at the bottom center of the rotating shaft fixing bracket 2, and the connecting rod 9 is plugged into the first bearing 6 at the top of the connecting block 7. The surface of the connecting rod 9 should be corrosion-resistant, smooth and shiny to facilitate insertion into the first bearing 6. A connecting hole is provided on the top of the chassis bracket 4, and the first bearing 6 at the bottom of the connecting block 7 is fixed in the connecting hole.
[0043] In some embodiments, such as Figure 6As shown, the second bearings 8 are embedded in the ears of both ends of the rotating shaft fixing bracket 2, and the two ends of the cable rotating shaft 1 are respectively plugged into and matched with the inner holes of the corresponding second bearings 8 through the shaft rod, so that the cable rotating shaft 1 can rotate freely. Specifically, in this embodiment, the shaft rod is octagonal, and the inner hole of the second bearing 8 is plugged into and matched with the shaft rod.
[0044] In some embodiments, such as Figures 6 to 10 As shown, umbrella skirts 10 are provided at the same distance points at both ends of the cable rotating shaft 1, and the inclined surfaces of the two umbrella skirts 10 are opposite. In this embodiment, the umbrella skirts 10 are made of gel-like PVC material. The umbrella skirts 10 can effectively prevent the sliding cable from derailing and causing damage to the device.
[0045] In some embodiments, the cable rotating shaft 1 is made of a gel-like PVC material, which is required to be light in weight, resistant to aging, and resistant to pressure. The rotating shaft fixing bracket 2 is made of a metallic galvanized rigid material. The entire device should have anti-oxidation and anti-aging functions, and the entire device needs to be anti-corrosive and have slightly special requirements.
[0046] The implementation principle of a cable laying device in this embodiment is:
[0047] The power cable is laid on the cable rotating shaft 1. When the cable is dragged, the cable rotating shaft 1 is driven to rotate by the downward force of the cable and the friction between the cable and the cable rotating shaft 1. The rotating shaft fixing bracket 2 can rotate 360° around the axis of the rotating shaft adjusting component 3 through the rotating adjustment component 3. No matter how the cable is turned during laying, the rotating shaft fixing bracket 2 can drive the cable rotating shaft 1 to turn to adapt to the turning angle of the cable, thereby reducing the risk of cable scratches caused by cable guide derailment.
[0048] The device has a good appearance and is safe to install. It avoids safety power accidents caused by cable scratches due to uncertain factors and causes economic losses during construction. The device is easy and simple to fix, easy to use, and has high operation convenience.
[0049] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
