Description

Technical Field

[0001] This utility model relates to the field of cable deformation testing fixtures, and in particular to a deformation testing fixture for cable production. Background Technology

[0002] A cable is a conductor consisting of one or more mutually insulated conductors and an outer insulating protective layer. It is laid underground, in the air, etc., and generally consists of three parts: a conductor, an insulation layer, and a protective layer. There are usually two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electrical energy; control cables are mainly used for measurement, protection, and control circuits. Cables are characterized by being internally energized and externally insulated.

[0003] Deformation is a mechanical term. Deformation is the process by which the relative positions of different parts of an object change under the action of external forces due to external factors or internal defects.

[0004] In the prior art, according to Chinese patent application number CN202411696175.0, an external deformation detection device for cable production is disclosed. This device includes a detection device body, a moving component, a pressure measuring component, a mounting block, a deformation detection camera, a protective frame, a clamping component, a display component, a signal component, and a gripping component. The moving component is located on the bottom surface of the detection device body, and the pressure measuring component is located inside the detection device body. Compared to traditional external deformation detection devices for cable production, which generally rely on manual sampling and offline measurement methods to detect cable external deformation (which is inefficient and makes it difficult to achieve real-time monitoring of the entire cable production process), this external deformation detection device for cable production, by setting up a ring-shaped distribution of deformation detection cameras, can accurately detect the type and degree of cable external deformation in real time, effectively ensuring the safety and stability of cable production.

[0005] In the prior art, according to Chinese patent application number CN202411696175.0, an external deformation detection device for cable production is disclosed. This device uses multiple cameras to observe and collect parameters from the outer circumference of the cable for corresponding detection. However, the cameras are connected to the cable clamping part, and the camera angles are fixed. If the cable moves, it will significantly affect the camera observation and hinder effective cable observation. Therefore, we propose a deformation testing fixture for cable production to solve the above problems. Utility Model Content

[0045] Operating principle:

[0046] The cable is inserted into the device from the top. Then, the A adjustment unit 8, with the positioning guide wheel 11, positions the cable. The angle of the camera 3 is then adjusted by the adjustment part 7. The cable is then pulled by the push unit 9 and the A drive plate 6, and the camera 3 observes and collects data at the center of the cable.
