Description

A cable retraction device for communication engineering

Technical field

The utility model relates to the technical field of communication engineering, and in particular to a cable retracting and unwinding device for communication engineering.

Background technique

Communication cables are communication lines composed of multiple mutually insulated wires or conductors twisted into a cable core and an outer sheath that protects the cable core from moisture and mechanical damage. Cables are used very frequently in communication construction work. Currently, When retracting and unwinding communication cables for communication engineering, take-up reels are used to retract and unwind the cables. The height between the existing take-up reel and the support base is fixed. When the take-up reel is wrapped with too many cables, the cables will rub against the support base, making it impossible to reel in more cables, affecting the take-up of the take-up reel. length, and it is inconvenient to cover the rolled cable, so that when the cable is exposed to the outside environment, the skin will easily crack, affecting normal use.

In order to solve the above problems, Chinese patent (Announcement No.: CN216403439U) discloses a communication cable retracting and unwinding device for communication engineering, which includes a supporting base plate, a rewinding assembly and a lifting assembly.

Above the bottom plate, the two ends of the rewinding turntable are symmetrically arranged, and the two ends of the rewinding turntable respectively pass through the center of the rewinding support plate.

The above solution adjusts the height of the rewinding component through the lifting component to rewind more cables. However, it is often necessary to replace a new rewinding drum after the rewinding is completed for the next rewinding, and one end of the rewinding turntable in the rewinding component It is connected with an anti-falling block, and one end is connected through motor drive and gear matching. If the rewinding turntable needs to be replaced, both ends of the rewinding turntable need to be disassembled. However, the rewinding turntable in the comparison document is not easy to replace, and because the rewinding turntable and the rewinding cable have a certain height and are heavy, replacement is time-consuming and laborious, which reduces its work. Efficiency; therefore, a cable retracting and unwinding device for communication engineering is needed to solve the above problems.
