[0026] As Figures 1 to 4 shown, an optical cable conveying device for communication engineering construction includes a trolley 1. A conveying mechanism 2 and a winding roller main body 3 are arranged on the upper surface of the trolley 1. A card slot is formed on the upper surface of the trolley 1. A balancing mechanism 4 for balancing the mass at the upper end of the trolley 1 is installed inside the card slot of the trolley 1. A limiting mechanism 6 is installed on one side of the balancing mechanism 4 away from the winding roller main body 3. Specifically, by arranging the balancing mechanism 4 and the winding roller main body 3 on the front and rear sides of the upper end of the trolley 1 respectively, the mass at the upper end of the trolley 1 can be balanced during the subsequent use of the balancing mechanism 4, so as to avoid the trolley 1 from tilting as much as possible when the subsequent staff push the device to move, thereby improving the safety of the subsequent staff when pushing the trolley 1 to move, and thus improving the practicability of the device.

[0027] As Figure 1 and Figure 2As shown, the balancing mechanism 4 includes a screw rod 401 and a motor 405. A positioning groove is formed on the upper surface of the trolley 1. The motor 405 is installed inside the positioning groove of the trolley 1. Through holes are formed on the inner walls of the front and rear sides of the card slot of the trolley 1. The screw rod 401 is rotatably connected inside the two through holes of the trolley 1. A first gear 406 is installed on the outer surface of the output shaft of the motor 405. The external teeth of the first gear 406 are meshed with a second gear 407. The second gear 407 is installed on the outer surface of the screw rod 401. A U-shaped fixing plate 402 is threadedly connected to the outer part of the screw rod 401. The U-shaped fixing plate 402 is slidably connected inside the card slot of the trolley 1. Three fixing rods 404 are installed on the upper surface of the U-shaped fixing plate 402. Multiple counterweight pieces 403 are sleeved on the outer surfaces of the three fixing rods 404;

[0028] Specifically, the positions of the balancing mechanism 4 and the winding roller main body 3 are respectively arranged on the front and rear sides of the upper end of the trolley 1, so that the mass of the upper end of the trolley 1 can be balanced during the subsequent use of the balancing mechanism 4, thereby minimizing the inclination of the trolley 1 when the subsequent staff push the device to move, and thus improving the safety of the subsequent staff when pushing the trolley 1 to move, and therefore improving the practicability of the device; By starting the motor 405 to drive the first gear 406 and the second gear 407 to rotate, the second gear 407 drives the screw rod 401 to trigger the U-shaped fixing plate 402 to slide inside the card slot of the trolley 1 during rotation, so that the staff can adjust the positions of the multiple counterweight pieces 403 on the upper end of the trolley 1 according to the mass of the winding roller main body 3, thereby minimizing the inclination of the subsequent trolley 1 to the side of the balancing mechanism 4 during use.

[0029] As Figure 1 and Figure 2 shown, a U-shaped protective cover 7 is installed on the back of the trolley 1. The positions of the second gear 407 and the first gear 406 are both inside the U-shaped protective cover 7; Specifically, since the position of the U-shaped protective cover 7 is located at the outer ends of the first gear 406 and the second gear 407, the U-shaped protective cover 7 shields the first gear 406 and the second gear 407, thereby minimizing the contact between the subsequent staff around the trolley 1 and the first gear 406 and the second gear 407 and causing injury to the staff, and therefore improving the safety of the device during use.

[0030] As Figure 3 and Figure 4As shown, a positioning slot is provided on the upper surface of the trolley 1. A slider 5 is slidably connected inside the positioning slot of the trolley 1. The upper surface of the slider 5 is mounted on the lower surface of the end of the U-shaped fixing plate 402 away from the screw 401. Specifically, by mounting the upper surface of the slider 5 on the lower surface of the end of the U-shaped fixing plate 402 away from the screw 401, the slider 5 restricts the movement path of one end of the U-shaped fixing plate 402 away from the screw 401, thus minimizing the risk of the connection between the U-shaped fixing plate 402 and the screw 401 being bent due to impact during subsequent movement of the U-shaped fixing plate 402. Therefore, the service life of the balance mechanism 4 is extended.

[0031] As Figure 3 and Figure 4 shown, the limiting mechanism 6 includes an L-shaped fixing plate 601. The L-shaped fixing plate 601 is mounted on the back of the U-shaped fixing plate 402. A slot is provided on the upper surface of the L-shaped fixing plate 601. A fixed sleeve 603 is slidably connected inside the slot of the L-shaped fixing plate 601. A hydraulic cylinder 602 is provided at the bottom of the inner wall of the slot of the L-shaped fixing plate 601. The output end of the hydraulic cylinder 602 is mounted on the top of the inner wall of the fixed sleeve 603. A groove is provided on the upper surface of the fixed sleeve 603. A rotating block 604 is rotatably connected inside the groove of the fixed sleeve 603. The lower surface of the rotating block 604 abuts against the upper surface of the top set of counterweight plates 403. Specifically, by rotating the rotating block 604, the position of the rotating block 604 is adjusted and moved directly above the top set of counterweight plates 403. Then, by activating the hydraulic cylinder 602 to pull the fixed sleeve 603 and drive the rotating block 604 to move downward, the lower surface of the rotating block 604 abuts against the upper surface of the top set of counterweight plates 403, enabling the limiting mechanism 6 to restrict the movement position of the multiple sets of counterweight plates 403 at the outer ends of the three fixed rods 404. Therefore, the stability of the multiple sets of counterweight plates 403 during subsequent use is improved.

[0032] As Figure 3 and Figure 4 shown, support blocks 8 are mounted on both the left and right inner walls of the U-shaped fixing plate 402. The upper surfaces of the two support blocks 8 abut against the top of the inner wall of the U-shaped fixing plate 402. Specifically, by mounting the two support blocks 8 at the corners of the left and right inner walls of the U-shaped fixing plate 402, the two support blocks 8 support the top of the U-shaped fixing plate 402, thus minimizing the risk of the top of the U-shaped fixing plate 402 being bent due to excessive load. Therefore, the service life of the U-shaped fixing plate 402 is extended.

[0033] In summary: By starting the motor 405 to drive the first gear 406 and the second gear 407 to rotate, the second gear 407 drives the screw rod 401 to trigger the U-shaped fixing plate 402 to slide inside the card slot of the cart 1 during rotation, so that the staff can adjust the positions of multiple sets of counterweight pieces 403 at the upper end of the cart 1 according to the mass of the winding roller main body 3, thereby minimizing the subsequent inclination of the cart 1 towards the balance mechanism 4 during use; by rotating the rotating block 604, the position of the rotating block 604 is adjusted and moved to the directly above the top set of counterweight pieces 403, and then by starting the hydraulic cylinder 602 to pull the fixed sleeve 603 to drive the rotating block 604 to move downward, the lower surface of the rotating block 604 is abutted against the upper surface of the top set of counterweight pieces 403, so that the limiting mechanism 6 restricts the moving positions of multiple sets of counterweight pieces 403 at the outer ends of the three fixed rods 404.
