Electric cable drum take-up and pay-off system

Abstract

The invention discloses an electric cable drum take-up and pay-off system which comprises a drum transfer device, a transmission group, a double-shaft transmission mechanism, a power group, a work group and a base. The work group comprises an electric cabled rum bracket and an electric cable drum, the base comprises a first region, a second region and a third region along linear directions, the work group is arranged in the first region, the power group is arranged in the second region, the double-shaft transmission mechanism and the drum transfer device are arranged in the third region, the double-shaft transmission mechanism comprises a first shaft, a second shaft and a first connecting piece, the first shaft is detachably connected with the second shaft by the first connecting piece, the power group is connected with the transmission group, and the power group and the double-shaft transmission mechanism are in linkage with each other via the transmission group. The electric cable drum take-up and pay-off system has the advantage that the electric cable drum can be electrically transferred by the drum transfer device, can be replaced in such a mode that the second shaft is detached but a chain of the transmission group is not detached, and can be efficiently and safely replaced in a labor-saving and space-saving manner.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a cable reel take-up and release system. Background technique [0002] The main grounding network of the substation plays the role of working grounding and protective grounding. When the grounding resistance is too large and a grounding fault occurs, it will threaten the equipment and reduce the lightning resistance level of the live conductor of the equipment, and the soil has a corrosive effect on the grounding device. In order to ensure that the equipment In order to ensure the safe and stable operation of the power grid, the substation grounding resistance test cycle shall not exceed 6 years. The cable required for a grounding resistance test is generally about 3000 to 10000m. Take-up and pay-off are completed. [0003] At present, the electric motor drives the wire reel to take up and pay off the wire: the generator supplies energy to drive the motor, the motor slows dow...

AI Technical Summary

Problems solved by technology

[0005] The existing cable reel take-up and pay-off system manually replaces the cable reel, which is highly dangerous;

[0006] When replacing the cable reel in the existing cable reel take-up and pay-off system, the chain used as the transmission group needs to be disassembled, which increases the work intensity and difficulty, and the efficiency is low
