Problems solved by technology

[0003] The existing test devices are all simple devices. Not only does the unwinding process not meet the actual use conditions, but also it is difficult to control the tension during winding, and the unwinding and winding processes require manual intervention, and the workload of repeating 10,0...

Abstract

The invention discloses a cable coil quality detection apparatus comprising a cable coil portion, an assistant reel portion and a grip hand wheel portion. Unreeling the cable coil is realized by grasping, pulling out and loosing the cable coil through an electromagnetic grip hand on the grip hand wheel. The grip hand wheel apparatus can simulate actual use condition of cable coil greatly. When reeling the cable coil, tension of the cable is converted to pressure of a force roller, and the tension is detected by a pressing magnetic force sensor mounted below the force roller and feeds the detection signal to a PLC control unit which controls magnetizing current of a magnetic particle clutch, an output torque of which is in approximately positive proportion to the magnetizing current so that tension of the cable is maintained in a target scale. The invention mainly aims to home use, commercial and similar use cable coil which demands high security indoor/outdoor.

Description

technical field [0001] The invention relates to a detection device, in particular to a cable drum quality detection device. Background technique [0002] The present invention refers to GB / T 19637-2005, the rated voltage of the cables used in the cable reel is 50V-250V in single-phase, and 50V-500V in other cases, which is much higher than the safe voltage of 36V. To ensure safety during use, the cable drum should withstand the mechanical, electrical and thermal stresses occurring in normal use without excessive wear or other harmful effects. Based on this, test inspection must be carried out in accordance with GB / T 19637-2005. The standard requires the operation test as follows: (1) unwind the flexible cable from the cable reel at a maximum speed of 0.5m / s toward the most likely direction during normal use, and then rewind it into the cable reel; (2) when unwinding , in line with normal use requirements, that is, the unwinding process should be as close to the actual use ...
