Cable measurement device

Abstract

The invention provides a cable measurement device. A fixed roll and a measurement roll parallel to each other are arranged in an outer frame. A movable shaft can slide along a fixed rod. A clamping spring is connected between one end part of the movable shaft and the outer frame on the outer side of the movable shaft. Clamping rollers arranged in parallel and in pairs is arranged on a plane defined by the fixed shaft and the movable shaft. Two ends of the clamping rollers in pairs both penetrate through a support frame and can slide towards each other. One movable roller is provided with a displacement sensor and is also provided with a length sensor and a measurement circuit. According to the invention, stable and accurate measurement of a cable metering device can be realized; cable release from the metering device when penetrating through the metering device quickly can be prevented during real time measurement of cable length and wire diameter of the cable penetrating through. Besides, the device is small in size and low in weight. The cable can penetrate through the device flexibly without obvious resistance. Offset is not caused in long term large scale measurement and measurement inaccuracy caused to cable jitter can be prevented. Measurement data can be uploaded for centralized analysis and management.

Description

technical field [0001] The invention relates to engineering measurement technology, in particular to a cable measurement device. Background technique [0002] The meter measurement of the cable passes through the metering device. In order to prevent the vibration of the cable during the measurement process, resulting in inaccurate metering, the invention patent application No. 2007201297345 "Precise meter meter device" uses a conveyor belt to increase the contact between the metering device and the cable Area method, but this method has a large volume in practical application, and its operation is not flexible, so it is difficult to promote. During the continuous movement of the cable, it may come out from the side of the conveyor belt, resulting in the loss of previous efforts in cumulative measurement, and all measurement data needs to be measured from the beginning, further reducing work efficiency.

During the continuous movement of the cable, it may come out from the side of the conveyor belt, resulting in the loss of previous efforts in cumulative measurement, and all measurement data needs to be measured from the beginning, further reducing work efficiency

[0003] The currently disclosed cable meter measuring device can only measure the length of the cable, and the diameter of the cable directly affects the quality and engineering planning of the cable, and any local problem in the entire cable will directly affect the entire cable. The quality of the cable

The detection of the continuous change of the cable diameter is of special significance for the quality inspection of the cable and the discovery of the sudden change of the local wire diameter of the cable. Identify possible problems in cables
