Most of them are designed for specific product models and production processes. The coupling degree between the equipment and the detection algorithm is high, and the versatility and flexibility are insufficient, which cannot meet the needs of all-round, high-precision, and high-efficiency non-destructive inspection of high-voltage cable segmented conductors.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] The utility model provides a full-angle visual measurement device for a split conductor, comprising: a control mechanism 1, a lifting unit 2, a moving card block 3, a tilting unit 4, a motion collection device 5, a signal isolation shell 6, an optical device 7, and a device body 8 as a whole.

[0032] The control structure 1 realizes precise control of the card block movement through external button commands and internal motor movement, and synchronously regulates the lifting and tilting units of the equipment body.

[0033] The control structure is provided with three rotating buttons 11 on both sides of the left and right sides of the equipment body, which is convenient for going online on different sides. One is to control the contraction and expansion of the card block by rotating the knob forward and reverse, the second is to control the rise and fall of the equipment body by rotating the knob forward and reverse, and the third is to control the tilt and horizontal placement of the equipment body to zero by rotating the knob forward and reverse. In addition, an emergency stop button 12 is provided.

[0034] The lifting unit 2 is responsible for detecting and controlling the equipment body to achieve rising, falling and fixed height positioning within a preset range. This design is designed to flexibly adapt to the changing needs of different production line heights. The main body of the lifting unit is supported by four steel column bearings 21, and the connecting shaft is fixed inside the body and controlled by a motor.

[0035] The movable clamping block 3 is arranged at the front and rear ends, and is composed of a double roller structure, with a circular structure that is empty inside, and is controlled by a motor to open and close left and right.

[0036] The tilting unit 4 is used to detect and adjust the tilt angle of the equipment body. Through the precision control device, it ensures that the equipment body can be tilted according to specific requirements, effectively responding to various tilting situations that may occur in the production line, so as to achieve all-round adaptive adjustment. The tilting unit uses an intermediate bearing support 41 to control the tilt angle through the height difference of the bearing.

[0037] The core structure of the motion acquisition device 5 includes a coding wheel 51 and a matching encoder 52. The bottom of the coding wheel innovatively adopts a spring support structure. When the high-voltage split conductor drives the coding wheel to roll during movement, it can accurately trigger and transmit the position signal to the relevant software system, thereby realizing real-time acquisition of the motion trajectory.

[0038] The signal isolation housing 6 adopts a hydraulic opening and closing rod 61 to facilitate the instrument to go online. After the housing is closed in the high-voltage workshop, it can effectively block the interference of external signals on the detection instrument, ensuring that the signal obtained by the detection instrument is pure and accurate.

[0039] The acquisition device 7 described in the optical device is constructed by a LED parallel light source and a high-precision CCD camera, which are arranged at parallel angles to achieve efficient collaborative operation. A slide rail 71 is arranged on the side to facilitate multi-angle detection. A dust removal fan 72 is arranged on the top of the side to ensure that potential dust interference is removed during the continuous image acquisition process.

[0040] The device body 8 is equipped with a pulley system 81 for easy movement and a stable adjustable support frame structure 82 at the bottom, which carries the support shaft assembly and the integrated core control structure body to ensure the stable operation and precise control of the entire device. Two fans 83 are set on the side wall to form an effective air convection channel, one is responsible for introducing air and the other is responsible for exhausting hot air to achieve constant temperature heat dissipation management inside the body. At the top of the body, the lifting and adjusting unit and the angle tilting unit are integrated, the optical device is embedded in the top, and a signal isolation shell is attached to the outside.

[0041] The above is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model are included in the protection scope of the utility model.
