Description

Technical Field

[0001] The utility model belongs to the technical field of cable lowering swing amount alarm, in particular to a cable lowering swing amount alarm device. Background Art

[0002] A cable is a device used for the transmission of electrical energy or signals, usually consisting of several or several groups of wires. These wires can be insulated from each other and wrapped by an outer insulating protective layer. As one of the infrastructures of modern society, cables play an important role.

[0003] In the prior art, in mobile power supply, when cables of different specifications on the cable reel are released through the guide, the speed of the motor winding the cable is slower than the speed of the trolley, so the cable generates tension. When the existing guide generates a signal of an over-tightened state position, the signal to the photoelectric switch lags, the tension of the trolley pulling the cable is greater than the tension of the cable itself, and the cable will be broken.

[0004] During long-term observation, it was found that the specifications of cables used were increasing, and the phenomenon of cables being broken was increasing, which increased customers' maintenance costs and reduced productivity.

[0005] To this end, the utility model provides a swing amount alarm device when the cable is lowered. Utility Model Content
