In the construction process of plastic reel laying can not be fully mechanized operation, artificial work heavier weight. Moreover, the cable used VV35mm2, VV50mm2 or even VV70mm2, this large-diameter power plastic coil factory coil is coiled in a disc, the length of up to several kilometers and since the major, human can not move the line plate, Can only be placed on the ground and rely on artificial manual release traction wear, in order to keep pace with the thread traction line to avoid hauling stop and go before the start of the traction work but also from the pre-set a certain length of plastic tray Line plate, by a few construction personnel custody pay-off. This mode of operation there are many drawbacks, inefficient, take up more manpower, increase the amount of labor, drag the plastic disc and the ground friction caused by damage, but also by geographical constraints, in the face of a wider main road construction The project can still be used, and the backstreets of the narrow space is simply not open to play.

In addition, the construction projects are mostly concentrated in the hot summer, the project is large, short duration, high technical indicators, but also requires a compact construction process, one step can not keep up with the staff may cause workers to affect the progress of the project, which the construction The professional level of personnel, construction capacity and physical quality are a severe test.

 

    In order to improve the efficiency of construction and reduce the labor consumption of construction workers to ensure adequate physical fitness, our technical staff for the pay-off operation of this part of repeated research to design a simple and practical pay-off disk, put into practical application received The effect is quite significant.

 

    It is made of steel plate, steel bar and channel steel (the material size can be customized). Its structure is designed as follows: symmetrically placed in a channel as the bottom fixed support foot, made of two steel plates, The upper part of the rotating disk, the lower part of the fixed disk, the fixed disk surface welded to the channel surface, and then made of a steel bar center rod, one end of the wire can be screwed into the rotating disk center bearing silk mouth, Lifting equipment. The structure diagram is as follows: (Sketch drawn in software is equivalent to the actual object) Remove the center pole before lifting, place the cable reel on the rotating disc, then screw the center rod through the center hole of the reel into the bearing Line with 2-3 custody of the line in the traction resistance can be a little power to help rotate the rotating disk, not only eliminates the pre-release of plastic reel this step, but also reduces the number of players, and the line with the The pay-off disk can be moved as a whole, and the maneuverability is strong. It is important to note that the rotation of the bearing lubrication and maintenance, so as not to affect the natural oxidation and corrosion performance.

 

    This equipment is simple in structure, reasonable in design and convenient in handling, which not only solves many of the problems mentioned above, but also enables the semi-mechanized operation of the pay-off operation. More importantly, since the pay-off disk small and flexible, can be placed near the laying of the nozzle, the traction line directly into the tube, to avoid the ground friction plastic wire insulation damage, effective protection of the plastic reel integrity, which works Quality assurance play a small role.
