Support blocks 7 are fixedly arranged on the top of the two jacking assemblies 6, and a lifting plate 8 is fixedly arranged on the top of each support block 7.

[0036] For example, the jacking component 6 can adopt a hydraulic cylinder, the piston rod of the hydraulic cylinder is fixedly connected to the lifting plate 8 through the support block 7, and the lifting plate 8 is driven up and down by the piston rod of the hydraulic cylinder. The hydraulic cylinder is used as the jacking component 6, which has a simple structure, large output, stable and reliable performance, smooth movement, and a self-locking function, and is easy to use and maintain.

A bearing ring 10 is fixedly provided on the inner wall of each through hole 9, and both ends of each cable support shaft 13 are respectively supported on the bearing rings 10 of the two lifting plates 8.

[0039] For example, three cable support shafts 13 can be provided, and three through holes 9 are correspondingly provided on each lifting plate 8 . A bearing ring 10 is provided in each through hole 9 , and both ends of each cable support shaft 13 are supported on two bearing rings 10 .

[0040] like Figure 1 As shown, for example, the two lifting plates 8 are parallel to each other, and the two lifting assemblies 6 rise and fall synchronously to push the cable support shaft 13 on the lifting plates 8 to move up and down, so that it can be suitable for wire coils of different diameters. Lifting rods 11 are fixed at both ends of the bottom of the two lifting plates 8, and vertical lifting sleeves 12 are fixed at the four corners of the top of the cable placement plate 21. The outer wall of the lifting rod 11 is slidably connected to the inner wall of the lifting sleeve 12.

[0041] like Figure 2 and Figure 3 As shown, for example, the laying-out device for communication optical cable construction also includes a fixing plate 4 and a positioning wheel 5.

The spiral pin assembly 16 includes a pin and a nut. One end of the pin is provided with an external thread, and one end of the pin passes through the plug hole 15 and is threadedly connected with the nut. The limiting plate 14 and the spiral pin assembly 16 inserted in the plug hole 15 can prevent the cable support shaft 13 from falling off on the two bearing rings 10.

[0045] The laid coils of cables, optical cables, etc. are placed on the top of the cable placement plate 21, and the cable support shaft 13 passes through the coils of cables, optical cables, etc. The output shafts of the two jacking components 6 are extended and retracted to make the through holes 9 of the two lifting plates 8 aligned with the two sides of the cable support shaft 13 respectively. The two ends of the cable support shaft 13 are inserted into the bearing ring 10, and the height of the two lifting plates 8 is raised by the output extension of the jacking component 6 to support the coils, and one end of the multiple coils of cable are respectively passed through the wire port 3 and the wire groove of the positioning wheel 5 into the bottom of the cable placement plate 21. By moving the pay-off device of the present invention, multiple coils of cable can be discharged at the same time, and all cables in the tunnel can be laid at one time, which greatly improves the laying efficiency of the tunnel cables.

[0046] like Figure 3 As shown, for example, the wire-laying device for communication optical cable construction also includes a traction plate 17 , a traction rod 18 and a push rod assembly 20 .

[0047] Among them, the traction plate 17 is fixedly set at one end of the cable placement plate 21, and a vertically upward traction rod 18 is fixedly set at one end of the top of the traction plate 17. A positioning hole 19 is opened on the top of the traction rod 18, and a matching fixing pin is arranged in the positioning hole 19. The traction rod 18 is used to conveniently connect the present invention with the traction device in the subway track, and the traction device is used to conveniently drive the present invention to move quickly on the subway track.

[0048] For example, the traction plate 17 can be integrally formed with the cable placement plate 21, or connected to the cable placement plate 21 by welding. For example, the traction plate 17 includes a trapezoidal connection portion and a square support portion, one end of the square support portion is fixedly connected to one end of the cable placement plate 21 through the trapezoidal connection portion, the corners of the square support portion are chamfered to avoid scratching the cable or the operator, an internal threaded hole is provided on the square support portion, one end of the traction rod 18 is provided with an external thread, and the external thread of the traction rod 18 is threadedly connected to the internal threaded hole on the square support portion, so as to achieve a fixed connection between the traction plate 17 and the traction rod 18.

[0050] For example, the push rod assembly 20 includes two support rods and a handle, and the handle is fixedly connected to the cable placement plate 21 through the two support rods. For example, the two support rods and the cable placement plate 21 form a certain angle, so that a certain distance is left between the handle and the cable placement plate 21, which is convenient for the operator to push the wire-releasing device to move on the track through the handle.

[0051] When in use, the present invention is first moved into a subway tunnel, and the two limiting slide rails 1 at the bottom of the cable placement plate 21 are inserted into the subway track. The sliding rollers 2 installed on the inner walls of the two limiting slide rails 1 roll on the subway track, which facilitates the movement of the present invention in the subway tunnel.

[0052] At this time, the cable, optical cable and other wire reels that need to be laid are moved to the top of the cable placement plate 21, and the cable support shaft 13 passes through the cable, optical cable and other wire reels. The output shafts of the two jacking components 6 are extended and retracted to make the through holes 9 of the two lifting plates 8 aligned with the two sides of the cable support shaft 13 respectively, and then the pin of the spiral pin assembly 16 is inserted into the plug hole 15 of the cable support shaft 13. The limit plate 14 on one side of the cable support shaft 13 and the spiral pin assembly 16 on the plug hole 15 can prevent the cable support shaft 13 from falling off the bearing ring 10. The height of the two lifting plates 8 is raised by extending the output of the jacking component 6. The two lifting plates 8 drive the wire reels to rise through the cable support shaft 13 to prop up the wire reels.

[0053] Pull out one end of the cable, optical cable and other wire reels, and insert one end of the cable, optical cable and other wire reels into the bottom of the cable placement plate 21 through the wire opening 3 and the wire groove of the positioning wheel 5 respectively, and then fix one end of the cable, optical cable and other wire reels at the specified position. At this time, the sliding roller 2 in the two limiting slide rails 1 provided at the bottom of the cable placement plate 21 moves on the subway track, and one end of the cable, optical cable and other wire reels is fixed. The cable, optical cable and other wire reels on the cable support shaft 13 are supported on the top of the cable placement plate 21 by the lifting rod 11. The cable support shaft 13 rotates in the positioning hole 19 through the bearing ring 10. The cable, optical cable and other wire reels rotate, and the cables and optical cables can be quickly released simultaneously in the subway tunnel.

[0054] The traction device in the subway track, such as a rail car, is connected to the traction rod 18, and the rail car is used to drive the present invention to move quickly on the subway track to achieve rapid wire release. The push rod assembly 20 can also be used to push the present invention to move in the subway tunnel.
