[0002] Cables are heavy, and various auxiliary equipment are usually required when laying them. For example, when laying cables in some narrow spaces (such as subway cables), a cable-laying trolley is usually used to move the cable reel, and the cable is placed in the corresponding space during the movement of the trolley.

[0003] For example, Chinese patent CN220896299U discloses a cable laying device, which includes a guide roller, a conveying mechanism and a cable limit frame, thereby automatically unfolding the wound cable on the cable reel and assisting workers to lay the unfolded cable in the landfill pit.

[0019] In order to better achieve the purpose of the present invention, the present invention also provides a method for using a cable installation auxiliary device, comprising the following steps:

[0020] Step 1: Insert the mounting block and the plug rod on the rotating table into the slot and the mounting groove to fix the cable drum on the rotating table; pass the end of the cable on the cable drum through the movable slot in the middle of the rotating frame and the four guide wheels on the support frame;

[0021] Step 2: The screw linear slide drives the mounting platform to move vertically, thereby driving the end of the cable to move vertically through the first swing arm, the second swing arm, and the support frame until the vertical height of the cable between the guide wheels is higher than the cable fixing frame; the electric push rod drives the second swing arm to rotate, and the second swing arm drives the first swing arm and the support frame to rotate, thereby driving the cable between the guide wheels to move directly above the cable fixing frame;

[0023] Step 4: When the moving speed of the flatbed trolley is less than the release speed of the cable, the cable sags between the cable drum and the guide wheel until the cable contacts the bottom of the movable groove and presses down the movable groove; the rotating frame moves downward under the action of gravity, driving the movable plate to move, and the movable plate moves vertically downward under the limiting action of the first slider and the guide rail, thereby driving the transmission sleeve to move downward, so that the second plug-in block inside the transmission sleeve is separated from the first plug-in block; the rotation of the first plug-in block no longer drives the rotation of the second plug-in block, so that the flatbed trolley moves forward and no longer drives the rotation of the turntable; at this time, the spring is compressed;

[0024] Step 5: After the cable is laid between the cable drum and the guide wheel, the cable no longer presses down the rotating frame, the spring reset drives the movable plate to reset, and the movable plate reset drives the transmission sleeve and the second plug-in block to reset;

[0025] Step 6: Repeat steps 3, 4, and 5 until the cable laying is completed.

[0026] Compared with the prior art, the present invention has the following advantages: 1. The cable reel with the cable is mounted on the rotating table through the mounting assembly, the end of the cable is passed through the protective adjustment assembly and the pay-off assembly, and the pay-off assembly is operated to move the end of the cable to the corresponding cable fixing frame; thus, during the cable pay-off process, the cable can be directly placed on the cable fixing frame, which facilitates cable installation;

[0027] 2. Operate the flatbed truck to move within the laying space. During the movement, the flatbed truck drives the turntable to rotate through the transmission components and the connection components. The rotation of the turntable drives the cable reel to rotate, thereby releasing the cable on the reel. During this process, the cable is guided by the protective adjustment component to avoid friction with other objects and avoid excessive bending of the cable, thereby protecting the cable.

[0028] 3. If the length of the cable released by the reel is greater than the moving distance of the flatbed truck, the cable will be pressed on the protective adjustment component, and the protective adjustment component will press down the connecting component to disengage the connecting component from the transmission component. At this time, the flatbed truck will move forward, and the rotation of the wheels will no longer drive the turntable to rotate through the transmission component and the connecting component. The reel on the turntable will temporarily stop releasing the cable; until the cable on the protective adjustment component is laid on the corresponding cable fixing bracket as the flatbed truck moves; avoid pulling the cable when releasing it, and avoid releasing too much cable.

The rotation of the ring gear 316 drives the rotating table 11 to rotate, thereby driving the cable drum 6 on the rotating table 11 to rotate, and the cable 7 on the cable drum 6 is released.

[0060] Step 4: When the moving speed of the flatbed trolley 1 is less than the release speed of the cable 7, the cable 7 sags between the cable drum 6 and the guide wheel 57 until the cable 7 contacts the bottom of the movable groove 46 and presses down the movable groove 46; the rotating frame 45 moves downward under the action of gravity, driving the movable plate 43 to move, and the movable plate 43 moves vertically downward under the limiting action of the first slider 42 and the guide rail 41, thereby driving the transmission sleeve 321 to move downward, so that the second plug 322 inside the transmission sleeve 321 is separated from the first plug 314; the rotation of the first plug 314 no longer drives the rotation of the second plug 322, so that the flatbed trolley 1 moves forward and no longer drives the rotating table 11 to rotate; at this time, the spring 44 is compressed;

[0061] Step 5: After the cable 7 is laid between the cable drum 6 and the guide wheel 57, the cable 7 no longer presses down the rotating frame 45, the spring 44 resets and drives the movable plate 43 to reset, and the movable plate 43 resets and drives the transmission sleeve 321 and the second plug block 322 to reset;

[0062] Step 6: Repeat steps 3, 4 and 5 until the cable 7 is laid out.
