Description

Technical Field

[0001] The utility model relates to the technical field of communication construction laying-out devices, in particular to a communication construction laying-out device. Background Art

[0002] Cables can be divided into power cables, communication cables and control cables according to their uses. Compared with overhead lines, the advantages of cables are small insulation distance between lines, small space, underground laying without occupying space above the ground, not affected by surrounding environmental pollution, high power transmission reliability, and little interference with personal safety and the surrounding environment. After the cable is produced, it is mostly rolled on a drum, and then the drum is transported to the area where it needs to be installed or replaced, and then the drum is placed inside the pay-off device. Finally, one person pulls one end of the cable, and the other person rotates the pay-off device to pay off the cable rolled on the drum, so that it can be used in communication construction.

[0003] However, most of the existing wire-laying devices are composed of a base, a support seat, and a rotating shaft, with a single structure. During the wire-laying process, when the wire-laying speed is too fast, the cable on the winding roller will become loose or entangled, thereby affecting the normal wire-laying work. Therefore, we propose a communication construction wire-laying device to solve the above problems. Utility Model Content

[0008] Preferably, the threaded rod is threadedly connected to the fixed connection block, the top of the threaded rod is conical, and the threaded rod and the first gear are on the same vertical line.

[0009] Preferably, the connecting frame is connected to the fixing rod via a first roller, and the fixing rod is connected to a limiting groove on the first roller via a limiting rod.

[0010] Preferably, the top of the connecting frame outside the second roller is connected to the bottom of the connecting frame through a rotating shaft.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the communication construction laying device:

[0012] (1) An elastic structure consisting of a first slide groove, a front connecting rod, a rear connecting rod, a spring, an extrusion plate, and a rotating roller is arranged on the top of the cable drum, so that the cable on the lower cable drum that is being paid out is squeezed, thereby avoiding the problem of the cable being loosened during the paying out process.

In addition, the first gear on the rotating shaft connected to the left side of the cable drum is fixed by a threaded rod in the bottom fixed connecting block, so that the rotation of the cable drum can be limited by the movement of the threaded rod, so that after the paying out is completed, the cable drum will not be rotated by external force;

[0013] (2) A cable-releasing structure is formed at the front end of the cable drum by an extension frame, a fixing rod, a limiting rod, a first roller, a connecting frame, and a second roller, so that the cables can be combed during cable-releasing to avoid entanglement between the cables during pulling. At the same time, the connecting frame outside the second roller is connected to the bottom of the connecting frame through a rotating shaft, so that the staff can pull the cables in different directions, thereby avoiding the cables from being bent at the second roller and then being damaged.

[0022] The extrusion plate 7 forms an elastic structure at the bottom of the extension plate 2 through the front connecting rod 4, the rear connecting rod 5, and the spring 6, so that the cables on the cable drum 9 at the lower end of the extrusion plate 7 are squeezed by the force of the spring 6 to avoid the problem of cables being entangled and loose when paying out the cables. The tops of the front connecting rod 4 and the rear connecting rod 5 form an active structure with the extension plate 2 through the first slide groove 3, so that the connecting structure can be deformed to change the position of the extrusion plate 7.

[0023] The extrusion plate 7 is an arc-shaped structure, which is convenient for fitting the cable on the cable drum 9, and the rotating roller 8 is connected to the bottom of the extrusion plate 7 through a rotating shaft. The rotating roller 8 can reduce the friction of the extrusion plate 7 on the cable surface and limit the cable on the cable drum 9 at the same time.

[0024] The threaded rod 13 is threadedly connected to the fixed connecting block 12, and the top of the threaded rod 13 is conical, and the threaded rod 13 and the first gear 11 are on the same vertical line, so that the rotation of the threaded rod 13 drives the conical structure on the top to engage with the gear, thereby fixing the rotation of the cable drum 9.

[0025] The connecting frame 18 is connected to the fixed rod 15 through the first roller 17, so that when the line is released, the connecting frame 18 can move along with the position of the line release to avoid the cable on the cable drum 9 from being entangled due to the position relationship, and the fixed rod 15 is connected to the limiting groove on the first roller 17 through the limiting rod 16 to avoid the problem of slipping and rotating of the connecting frame 18 when moving.

[0026] The top of the connecting frame outside the second roller 19 is connected to the bottom of the connecting frame 18 through a rotating shaft, so that the cable will not be stuck on the second roller 19 when the staff pulls the cable in all directions.

[0027] Working principle: When using the communication construction laying device, first, before laying the line, the threaded rod 13 in the fixed connecting block 12 under the first gear 11 outside the rotating shaft 10 on the left side of the line rotating support seat 1 is disengaged from the outer tooth plate of the first gear 11, and then the cable on the cable drum 9 is passed through the second roller 19 at the bottom of the connecting frame 18 of the fixed rod 15 in the extension frame 14, and then the cable is started to be pulled. The cable will drive the second roller 19 to rotate. At the same time, as the cable is pulled, the connecting frame 18 also moves on the fixed rod 15 through the first roller 17, thereby reducing the resistance caused by the different positions of the cable on the cable drum 9 during the pulling process. At the same time, the second roller 19 will also rotate following the pulling of the staff to avoid the problem of the cable and the second roller 19 being stuck due to the wrong angle.

[0028] As the cable on the cable drum 9 is pulled out, the surface of the cable drum 9 gradually becomes smaller, and at the same time, the extrusion plate 7 is subjected to the reaction force of the spring 6, thereby moving inward to squeeze and limit the cable on the cable drum 9. At the same time, the rotating roller 8 at the bottom of the extrusion plate 7 will also contact the cable on the cable drum 9, and then rotate with the rotation of the cable drum 9, reducing the friction between the cable and the extrusion plate 7, thereby avoiding the problem of the cable on the cable drum 9 becoming loose and entangled as the cable drum 9 is unwound. After the unwinding is completed, the threaded rod 13 in the fixed connecting block 12 is rotated so that the conical structure at the top of the threaded rod 13 engages with the outer teeth of the first gear 11 on the outer side of the rotating shaft 10 on the left side of the cable drum 9, thereby fixing the cable drum 9.
