Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber cable technology, and more specifically, to an optical fiber core laying device for optical fiber cables. Background Technology
[0002] Fiber optic cable is a type of communication cable consisting of two or more glass or plastic optical fiber cores encased in a protective cladding and covered by a plastic PVC outer sheath. When laying cables underground, a cable trench needs to be dug in the ground beforehand, the trench walls are then mixed and poured with a mortar, and the cable is laid inside the trench.
[0003] A search revealed that utility model patent CN217182786U discloses a fiber optic cable core laying device, including a cable roller and a base. Two fixing plates and a fixing frame are arranged above the base. The fixing frame is located on one side of the two fixing plates. A rotating rod for mounting the cable roller is fixedly connected between the two fixing plates. A trolley is arranged on one side of the base. Two mounting plates are arranged above the trolley. A connecting rod and a connecting plate are fixedly connected between the two mounting plates. The connecting plate is located above the connecting rod. An extension screw is threaded onto the connecting plate. A clamping block is provided at the bottom end of the extension screw. A cylinder is fitted over the connecting rod. The cable can be wound around the cylinder. Then, rotating the extension screw clockwise causes the extension screw to drive the clamping block down onto the wound cable, compressing the cable and increasing its strength, making it less likely to fall off when pulled.
[0004] However, the above-mentioned patent still has the following shortcomings: it requires manual pulling to move the device, which wastes a certain amount of physical strength and affects the laying efficiency; in addition, optical cables are generally packaged in rolls and have a certain weight, which is not convenient for loading. Therefore, we have proposed an optical fiber cable fiber core laying device. Utility Model Content

Each of the two U-shaped frames has a drive wheel rotatably connected to its inner side. Servo motors are fixedly mounted on the sides of the frame. The output shafts of the two servo motors are respectively connected to one end of the shafts of the two drive wheels. Two rotating columns are rotatably connected to the base plate via bearings. The bottom ends of the two rotating columns extend to the bottom of the base plate and are fixedly connected to moving wheels. The top ends of the two rotating columns extend to the top of the base plate and are fixedly sleeved with second spur gears. A pull rod is rotatably connected to the base plate via bearings.

A spring is fixedly connected to the top surface of each of the two support seats. A pull block is fixedly connected to the top of each of the two springs. A pin is fixedly connected to the bottom surface of each of the two pull blocks. The bottom end of the pin is movably sleeved into the inner cavity of the insertion hole.
[0008] As a preferred embodiment of the present invention, the feeding mechanism includes a rotating groove disposed at the end of the base plate and a support frame fixedly connected to the bottom surface of the base plate.

[0009] In a preferred embodiment of this utility model, a handle is fixedly connected to the top of the pulling rod, and a control panel is provided on the bottom surface of the handle. The control panel is electrically connected to the servo motor and the hydraulic cylinder respectively.
[0010] In a preferred embodiment of this utility model, the side of the square column is fitted to the inner wall of the outer protective cylinder.
[0011] In a preferred embodiment of this utility model, the inner diameter of the support hole is equal to the outer diameter of the support column, and the outer diameter of the pin is equal to the inner diameter of the insertion hole.
[0012] Compared with the prior art, the advantages of this utility model are: (1) In this utility model, the servo motor drives the drive wheel to rotate, the drive wheel drives the device to move forward, and the hand holds the handle to drive the pull rod and the first spur gear to rotate. The meshing transmission between the first spur gear and the rack drives the rack to move. The meshing transmission between the rack and the two second spur gears drives the rotating column and the moving wheel to rotate, so as to use the rotation of the moving wheel to steer the movement of the device, thus realizing the function of driving the device to move by itself.
[0013] (2) In this utility model, the first feeding frame, the second feeding frame and the support frame work together to roll the take-up drum located on the ground to the inside of the two outer protective cylinders, and make the support hole and the through hole on the take-up drum aligned. The support column is inserted into the support hole and the through hole on the take-up drum. The spring force drives the pin to be inserted into the insertion hole to fix the support column. The hydraulic cylinder drives the square column and the take-up drum to move upward, lifts the take-up drum, and releases the optical fiber cable on the take-up drum. This realizes convenient feeding of the take-up drum and has good practicality. Attached Figure Description

[0034] Working principle: In use, firstly, unfold the first loading rack 30 and the second loading rack 31 folded on the base plate 1, so that the support frame 29 supports the first loading rack 30 and the second loading rack 31. At this time, the bottom end of the second loading rack 31 is in contact with the ground, so that the take-up drum 4 can be rolled onto the base plate 1 through the second loading rack 31 and the first loading rack 30. At this time, the hydraulic cylinder 19 is activated to drive the square column 20 and the support base 21 to move down, so that the support hole 22 and the through hole on the take-up drum 4 are aligned. Then, the support column 23 is inserted into the support hole 22 and the through hole on the take-up drum 4. The elastic force of the spring 25 drives the pin 27 to be inserted into the insertion hole 24, and the support column 23 is used to fix the take-up drum 4. At this time, the hydraulic cylinder 19 is activated to drive the square column 20, the support base 21 and the take-up drum 4 to move up, so that the take-up drum 4 can be rolled onto the base plate 1. The fiber optic cable can be released, and then one end of the fiber optic cable on the take-up drum 4 is pulled into the laying trench, so that the base plate 1 is placed directly above the trench. At this time, the servo motor 15 is started by the control panel 17. The servo motor 15 drives the drive wheel 14 to rotate, and the drive wheel 14 drives the device forward. At the same time, the fiber optic cable wound on the take-up drum 4 is released. Finally, the handle 16 is held to drive the pull rod 6 and the first spur gear 7 to rotate. The meshing transmission between the first spur gear 7 and the rack 11 drives the rack 11 to move. The meshing transmission between the rack 11 and the two second spur gears 8 drives the rotating column 5 and the moving wheel 12 to rotate, so that the rotation of the moving wheel 12 can be used to steer the movement of the device.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
