TECHNICAL FIELD

[0001] The application relates to the technical field of electric power engineering, in particular to a diameter measuring device for cables. BACKGROUND

[0002] In the process of electric power operation, the diameter of a cable needs to be measured, because the outer diameter size of the cable actually reflects the thickness of the insulating layer, and the thickness of the insulating layer is crucial to the electrical performance and safety of the cable. By measuring the outer diameter of the cable, the thickness of the insulating layer can be indirectly understood, so as to ensure that it meets the design and safety requirements.

[0003] At present, in the process of measuring the diameter of the cable, a technician usually holds the cable end with one hand and holds a vernier caliper and other measuring tools with the other hand to measure the diameter of the cable. If the technician holds the cable unsteadily, the vernier caliper may shake during the measurement process, that is, the contact between the measuring tool and the cable is unstable, and thus measurement errors are caused.

[0006] Preferably, the driving mechanism comprises a gear ring frame rotatably connected to the outer surface of the disc frame, and a first shaft is fixedly connected to the outer surface of the gear ring frame. The driving mechanism can drive the gear ring frame, so that the three groups of rubber arc plates distributed uniformly along the axial hole are synchronously deflected.

[0007] Preferably, a driving strip is rotatably connected to the outer surface of the first shaft, a second shaft is fixedly connected to the outer surface of the rotating plate, and the outer surface of the second shaft is rotatably connected to the end of the driving strip away from the first shaft.

[0008] Preferably, a motor is fixedly installed on the disc frame, a gear is fixedly connected to the output end of the motor, and the outer surface of the gear is meshingly connected to the outer surface of the gear ring frame.

[0009] Preferably, a vernier caliper is slidably arranged in the device frame.

[0011] 1. The cable diameter measuring device, through the motor driving gear and the gear ring frame, realizes the automatic control and positioning of the rotating plate and the rubber arc plate, ensures that the rubber arc plate can be stably attached and closely attached to the outer surface of the cable, and the technician only needs to operate the vernier caliper during the measurement process, without adjusting the position of the cable, thereby effectively reducing the shaking and measurement error caused by the unstable hand of the technician.
