Technical Field

[0001] This utility model relates to the field of cable laying vehicle technology, specifically an energy-saving cable laying vehicle for communication networks. Background Technology

[0002] Communication cables are conductors used to transmit electrical or optical signals. They are usually composed of multiple core wires. During the construction of communication cables, a cabling vehicle is needed to lay the cables.

[0003] Traditional cable unwinding machines typically involve placing a whole roll of cable onto the machine and pushing it to release the cable. However, after unwinding the cable, it's not easy to replace the cable roll, making them inconvenient to use. Furthermore, during the cable unwinding process, the lack of constraint on the cable's outer wall can cause the cable to loosen on the roll, leading to tangling and hindering proper cable unwinding. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an energy-saving cable pulling cart for laying communication network cables, which has the advantages of facilitating the replacement of cable reels and the fixing of cables, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an energy-saving cable laying cart for communication networks, comprising a mobile cart, with support wheels and casters fixedly mounted on the bottom of the mobile cart; a push rod fixedly mounted on the outer wall of the mobile cart; a support rod fixedly mounted on the top of the mobile cart; a movable frame movably sleeved on the outer wall of the support rod; a limit plate fixedly mounted on the outer wall of the movable frame; an electric push rod fixedly mounted on the top of the mobile cart; a lifting groove formed on the outer wall of the movable frame; a lifting block movably sleeved within the inner cavity of the movable frame; and a support roller fixedly mounted on the outer wall of the lifting block. The inner cavity of the movable frame is fixedly equipped with a drive motor, and the power output shaft of the drive motor is fixedly equipped with a drive screw. The bottom of the inner cavity of the movable frame is fixedly equipped with a limit rod, the top of the movable frame is fixedly equipped with a top plate, and an auxiliary rod is installed on the top of the top plate. A lifting rod is movably sleeved on the outer wall of the auxiliary rod, a traction spring is movably sleeved on the outer wall of the auxiliary rod, a bearing rod is movably sleeved on the outer wall of the lifting rod, a movable groove is opened on the outer wall of the bearing rod, an insert rod is fixedly equipped on the outer wall of the lifting rod, a pressure roller is movably sleeved on the outer wall of the bearing rod, and a pay-off roller is tumbledly connected to the outer wall of the support roller.

[0006] As a preferred technical solution of this utility model: the outer wall of the support rod passes through the inner cavity of the limiting plate, and there are two movable frames, which are respectively movably sleeved on both sides of the outer wall of the moving vehicle.

[0007] As a preferred technical solution of this utility model: the outer wall of the drive screw passes through the inner cavity of the lifting block, and the outer wall of the drive screw is threadedly connected to the inner wall of the lifting block.

[0008] As a preferred technical solution of this utility model: the two ends of the outer wall of the traction spring are respectively connected to the outer wall of the lifting rod and the outer wall of the top plate, and the traction spring is made of high carbon steel.

[0009] As a preferred technical solution of this utility model: the outer wall of the insertion rod passes through the inner cavity of the movable groove, and the outer wall diameter of the lifting rod matches the inner wall diameter of the bearing rod.

[0010] As a preferred technical solution of this utility model: the power output shaft of the electric push rod is connected to the outer wall of the movable frame, the length of the inner wall of the movable groove is greater than the maximum moving distance of the movable frame, and the static unforced length of the traction spring is less than half the length of the outer wall of the auxiliary rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This energy-saving communication network cable laying trolley features a movable frame mounted on the top of the trolley. The position of the movable frame can be adjusted by an electric push rod. By changing the distance between the left and right movable frames, the installation and removal of the pay-off roller is facilitated. Furthermore, by lowering the height of the support roller, the outer wall of the support roller can be more accurately aligned with the inner cavity of the pay-off roller, thus making the replacement and installation of the pay-off roller more convenient.

[0013] 2. This energy-saving communication network cable laying trolley uses an auxiliary rod on the top of the moving frame and a lifting rod on the outer wall of the auxiliary rod. Under the action of a traction spring, the vertical position of the lifting rod can be adjusted, so that the outer wall of the pressure roller can contact the cable on the outer wall of the pay-off roller, thereby fixing the cable and preventing the cable from coming loose on the outer wall of the pay-off roller during the release process, thus better releasing the cable.

[0021] Please see Figure 1 - Figure 5 An energy-saving cable laying trolley for communication networks includes a mobile vehicle 1.

[0022] In the above structure, the position of the moving frame 6, which is set on the top of the moving vehicle 1, and the support rod 5, which is set on the top of the moving vehicle 1, can be adjusted under the action of the electric push rod 7, so that the moving frame 6 can move on the outer wall of the moving vehicle 1, thereby changing the distance between the outer walls of the two moving frames 6, so that the support roller 9 can be disengaged from the inner wall of the feeding roller 22, and the feeding roller 22 on the outer wall of the support roller 9 can be replaced.

[0023] In a preferred embodiment: the outer wall of the support rod 5 passes through the inner cavity of the limiting plate 8, and there are two movable frames 6, which are respectively movably sleeved on both sides of the outer wall of the mobile vehicle 1.

[0024] In the above structure, the position of the two movable frames 6 set on both sides of the outer wall of the movable vehicle 1 and the electric push rod 7 set on the bottom of the movable vehicle 1 can be adjusted under the action of the electric push rod 7, so that the distance between the outer walls of the two movable frames 6 can be adjusted, thereby realizing the installation and replacement of the wire feeding roller 22.

[0025] In a preferred embodiment, the outer wall of the drive screw 12 passes through the inner cavity of the lifting block 10, and the outer wall of the drive screw 12 is threadedly connected to the inner wall of the lifting block 10.

[0026] In the above structure, the drive motor 11 installed in the inner cavity of the moving frame 6 and the drive screw 12 installed on the power output shaft of the drive motor 11 will cause the drive screw 12 to rotate under the action of the drive motor 11, thereby driving the lifting block 10, so that the lifting block 10 can move up and down along the outer wall of the drive screw 12, and thus the support roller 9 will move up and down with the lifting block 10, changing the height of the support roller 9, thereby better realizing the replacement of the wire feeding roller 22.

[0027] In a preferred embodiment, the two ends of the outer wall of the traction spring 16 are connected to the outer wall of the lifting rod 18 and the outer wall of the top plate 14, respectively, and the traction spring 16 is made of high carbon steel.

[0028] In the above structure, the traction spring 16 provided on the outer wall of the auxiliary rod 15 can pull the lifting rod 18 under the action of the traction spring 16, so that the lifting rod 18 can move up and down along the outer wall of the auxiliary rod 15, thereby allowing the outer wall of the pressure roller 21 to contact the cable on the outer wall of the wire feeding roller 22, and fixing the outer wall of the cable.

[0029] In a preferred embodiment: the outer wall of the insertion rod 20 passes through the inner cavity of the movable groove 19, and the outer wall diameter of the lifting rod 18 matches the inner wall diameter of the bearing rod 17.

[0030] In the above structure, the support rod 17 provided on the outer wall of the lifting rod 18 will drive the auxiliary rod 15 and the lifting rod 18 to move synchronously with the movement of the moving frame 6 when the moving frame 6 on both sides moves outward. This allows the lifting rod 18 to move in the inner cavity of the support rod 17, thereby enabling the moving frame 6 to move smoothly on the outer wall of the moving vehicle 1.

[0031] In a preferred embodiment: the power output shaft of the electric push rod 7 is connected to the outer wall of the movable frame 6, the length of the inner wall of the movable groove 19 is greater than the maximum moving distance of the movable frame 6, and the static unforced length of the traction spring 16 is less than half the length of the outer wall of the auxiliary rod 15.

[0032] In the above structure, the electric push rod 7 installed at the bottom of the mobile vehicle 1 can drive the outer wall of the mobile frame 6 under the action of the electric push rod 7, so that the mobile frame 6 can move on the top of the mobile vehicle 1. During the movement of the mobile frame 6, the outer wall of the lifting rod 18 can move in the inner cavity of the bearing rod 17, so that the bearing rod 17 and the lifting rod 18 can still be erected on the top of the mobile frame 6.

[0033] Working Principle: During the cable laying process, the cable reel needs to be placed on the outer wall of the movable slot 19. The drive motor 11 is started, causing the drive screw 12 to rotate. During the rotation of the drive screw 12, the limit rod 13 restricts the lifting block 10, allowing it to rise and fall along the outer wall of the drive screw 12. This lowers the height of the support roller 9, moving it to the bottom of the movable frame 6. The electric push rod 7 then adjusts the movable frame 6 outwards, increasing the distance between the two movable frames 6. At this point, the pay-off roller 22 can be moved... On the top of the mobile vehicle 1, by adjusting the position of the wire feeding roller 22 and pushing the mobile frame 6, the outer wall of the support roller 9 enters the inner cavity of the wire feeding roller 22. Then, the drive motor 11 is started, and the drive screw 12 is rotated under the action of the drive motor 11, so that the lifting block 10 moves upward along the outer wall of the drive screw 12, thereby enabling the wire feeding roller 22 to move upward. At this time, the installation of the wire feeding roller 22 is completed. During the cable release process, the traction spring 16 will play a certain restrictive role on the outer wall of the pressure roller 21, so that the outer wall of the pressure roller 21 is in contact with the cable on the wire feeding roller 22, preventing the cable from coming loose from the outer wall of the wire feeding roller 22, and better performing the wire feeding work.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
