Description

Technical Field

[0001] The utility model relates to the technical field of cable retracting and releasing devices, and more specifically, to a cable retracting and releasing device for power transmission engineering construction. Background Art

[0002] During the construction of power transmission projects, cable retracting devices are often used to reel in and unwind cables. At present, cables are generally wound outside the drum after production. When unwinding, the winding drum is connected to the output shaft of the motor, and the winding drum is driven by the motor to rotate, thereby realizing the unwinding process. However, when the winding drum and the motor are assembled, a rotating shaft is provided at the end of the winding drum away from the motor, and the rotating shaft is inserted into a preset fixed frame and is rotatably connected to the fixed frame. The end of the winding drum close to the motor is connected to the motor shaft through a coupling, and the winding drum is supported by the rotating shaft, the coupling and the motor shaft. However, the weight of the winding drum and the cable is heavy, which can easily cause the rotating shaft, the coupling or the motor shaft to bend and deform, shortening the service life; in addition, the length of the winding drum is long. If the cable is directly driven to be wound outside the winding drum by the motor shaft drive, the cable will be concentrated at a certain position of the winding drum. When the winding drum is removed from the motor and carried, the cable is easily displaced on the winding drum, which can easily cause the cable to be loose, affecting the handling of the cable.
