Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a cable reel-type wire-reeling device. Background Art

[0002] In the process of cable cabling or cable laying, the cable reel is an indispensable storage device. In the process of cable reeling or unwinding, the cable reel needs to be rotated. However, the cable reel is huge and it is not easy to use the axis of the cable reel as a driving connection structure. Therefore, the vertical discs at both ends of the cable reel are often used as the driving connection structure.

[0003] In order to ensure the stability of the vertical plate drive of the cable reel, the traditional driving structure will place more than four driving wheels at the lower end of the vertical plate, and the driving wheels are independently driven to rotate. The driving wheels have both driving and supporting purposes, so that when one of the driving wheels fails, the other driving wheels can still ensure the continued operation of the vertical plate rotation, thereby ensuring the stability of the vertical plate drive. However, as the use time increases, it is found that during the driving process of more than four driving wheels, due to the different support strengths in different support areas, the mechanical transmission wear is different, and the rotation linear speed difference is prone to occur, resulting in uneven force on the vertical plate under the driving wheels in different areas, and stress concentration occurs, resulting in deformation of the vertical plate. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a cable stand reel retractable and retractable device which can avoid stress concentration on the stand reel and cause deformation while ensuring the stability of the stand reel driving.

[0006] Compared with the prior art, the utility model has the following advantages: in order to ensure the supporting stability of the vertical plate, auxiliary supporting wheels are used to replace part of the driving wheels, and only two driving wheels are retained to drive the vertical plate to rotate, thereby ensuring the supporting effect. At the same time, the two driving wheels are symmetrically arranged about the longitudinal center line of the vertical plate, so it is ensured that the supporting force and driving force between the two driving wheels and the vertical plate are the same when the rotation power of the two driving wheels is the same, so that the wear between the two driving wheels and the vertical plate is the same, and the vertical plate will not be unevenly stressed during the driving process, and stress concentration will not occur to cause deformation, thereby ensuring the service life of the vertical plate.

Through the improvement, the support height of the auxiliary support wheel is adjusted by the pressure sensor to ensure the support effect of the auxiliary support wheel, and at the same time, the consistency of the support effects of the two auxiliary support wheels can also be ensured.

[0010] As an improvement of the utility model, an arc groove is provided on a side of the connecting frame close to the vertical plate. Through the improvement, it can be avoided that the connecting frame and the vertical plate abut against each other after the connecting frame is changed.

[0011] As an improvement of the present invention, the connecting surface between the connecting frame and the supporting frame is arranged at an angle. At the connection between the connecting frame and the supporting frame, the connecting frame is arranged below the supporting frame. Through the improvement, the reaction force of the vertical plate received by the supporting frame can be transmitted to the connecting frame, thereby effectively reducing the strain of the supporting frame, thereby extending the service life of the supporting frame. After the connecting frame is damaged, it can be replaced.
