Abstract

The invention belongs to the technical field of cable detection, and relates to an automatic monitoring device for the overlapping width of a metal wrapping band of a cable. The device comprises a shell with an inner cavity, a timed discharge unit arranged in the cavity, a discharge switch K1, a discharge resistor R1, a central control unit, a motor driving unit, an external diameter acquisition unit, a timing unit, a display unit, a data storage unit, a data acquisition unit, a motor, a cable container arranged on a rotating shaft of the motor, a variable capacity capacitor C1 positioned in the cavity and consisting of a first electrode and a second electrode, a buffer resistor R2 and a power source S, wherein a cable accommodation cavity is formed in the cable container; a clamping part is arranged in the cable accommodation cavity; the power source S, the variable capacity capacitor C1, the buffer resistor R2 and the data acquisition unit are sequentially connected in series to form a power loop. The device has the main beneficial effects that the device is simple in structure, low in comprehensive cost and labor intensity and high in test speed, a test result is accurate, and stripping equipment is not required.

Description

technical field [0001] The invention belongs to the technical field of cable detection, and in particular relates to an automatic monitoring device and a monitoring method for overlapping widths of metal cladding tapes of cables. Background technique [0002] As the basic industry of the national economy, cables account for an increasing share of the total national economy. There are various types of cables. For cables with metal cladding tape, there is generally a requirement for the width of the overlapping joint of the cladding tape, whether it is an optical cable or an electrical cable. If the lap width is too small, the cable is easily cracked during construction torsion; and if the lap width is too large, it will not only cause waste of metal strips, but also cause the cable to crack under strong torsion. Therefore, control Good lap width is one of the most important tasks in the cable industry. [0003] For this reason, for the cable, usually the sheath of the cable...

Problems solved by technology

If the lap width is too small, the cable is easily cracked during construction torsion; and if the lap width is too large, it will not only cause waste of metal strips, but also cause the cable to crack under strong torsion. Therefore, control Good lap width is one of the most important tasks in the cable industry

[0003] For this reason, for the cable, usually the sheath of the cable is peeled off, and then the width of the overlapping part of the metal cladding tape is measured. Since the cable sheath is often glued to the metal cladding tape, therefore, Stripping the sheath is time-consuming and labor-intensive for cables with large cores and large diameters; even for small-core cables, special cable stripping knives or blades are required for stripping cables. , highly susceptible to passivation, therefore, the work of measuring metal-clad tape laps can be described as time-consuming and expensive

[0004] At present, there is no good solution in the industry to solve this problem
