High-voltage cable aluminum sheath protective belt take-up and pay-off device

Abstract

The invention belongs to the technical field of cable production, and particularly relates to a high-voltage cable aluminum sheath protection belt winding and unwinding device which comprises a protection belt, a winding drum, an unwinding trolley and a winding trolley. A creeling shaft assembly and a driven shaft assembly are arranged at the left end and the right end of the unwinding trolley chassis correspondingly. A creeling shaft assembly and a driving shaft assembly are arranged at the left and right ends of the winding trolley chassis; a creel changing shaft of the creel changing shaft assembly is arranged at the top end of a supporting frame in a sliding mode, a telescopic driver is installed on the supporting frame and coaxially and fixedly connected with the creel changing shaft, and the right end of the creel changing shaft can enter and exit and is coaxially arranged in a winding drum in a penetrating mode. The driven shaft assembly comprises a driven shaft and a support thereof, the driven shaft is rotationally arranged at the top end of the driven shaft support, the left end of the driven shaft coaxially penetrates through the winding drum I, and a brake device is arranged at the right end of the driven shaft; the driving shaft assembly comprises a driving shaft and a support thereof, the driving shaft is rotatably arranged at the top end of the driving shaft support, and the driving shaft is in transmission connection with a power motor, so that the idea that the outer side of the aluminum sheath is lined with a protective belt for protection is implemented.

Description

technical field [0001] The invention belongs to the technical field of cable production, and in particular relates to a retracting device for an aluminum sheath protective belt of a high-voltage cable. Background technique [0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits power or information from one place to another, and is a bridge between power supply equipment and electrical equipment. Cables can be roughly divided into low-voltage cables, medium-voltage cables, high-voltage cables and extra-high-voltage cables according to their withstand voltage levels. Among them, in the production process of high-voltage cables and ultra-high-voltage cables, the outer layer of the cable core generally needs to be longitudinally wrapped with a layer of aluminum sheath, and subjected to tie treatment, such as the high-voltage cable aluminum sheath described in CN201616294U and CN206104600U. In t...

Problems solved by technology

When the high-voltage cable is sheathed through the aluminum sheath, the aluminum sheath needs to travel together with the high-voltage cable. During the travel, it is easy to cause friction between the aluminum sheath and the equipment or friction between the aluminum sheath and the ground, and the aluminum sheath is not resistant In order to prevent the wear of the aluminum sheath, the production personnel thought of lining the protective belt on the outside of the aluminum sheath for protection during the process. The lack of a corresponding protective belt retractable device makes the implementation of this idea difficult
