Description

Technical Field

[0001] The utility model relates to a translation type transmission line high altitude flaw detection device, belonging to the technical field of transmission line nondestructive detection. Background Art

[0002] Overhead transmission lines are prone to failures such as cracking, deformation, ablation, and corrosion at the line body and key connections, posing a significant risk to safe operation. To eliminate these potential accidents, manual work at heights relies on tower climbing, which carries a risk of falling. Furthermore, workers must frequently ascend and descend towers to avoid radiation damage, resulting in inefficient inspections.

[0003] As an important non-destructive testing method, the "UAV + X-ray" detection technology has the advantages of high efficiency, convenience, and no personal safety risks. It has begun to be used as an alternative to manual tower climbing operations. The "UAV + X-ray" detection technology needs to rely on connecting components such as structural supports, and the role of structural supports is becoming increasingly obvious.

[0004] For example, the Chinese patent with the announcement number CN220582190U discloses a transmission line flaw detection device, which realizes lifting and rotating operations through the lifting drive assembly and the flipping drive assembly, and lowers or rotates the receiving imaging base plate and the X-ray machine to the position of shooting the lower conductor, so as to facilitate the detection of the sub-conductor tension clamps under the four-split conductor and expand the detection range.

[0005] However, the area of ​​the receiving imaging base plate is fixed, so that the space for detection between the receiving imaging base plate and the X-ray machine is limited, resulting in low detection efficiency. Utility Model Content

[0006] The purpose of the utility model is to provide a translational transmission line high-altitude flaw detection device to solve the problems raised in the above background technology.

[0007] The technical solution of the utility model is as follows:

[0008] A translation type transmission line high altitude flaw detection device, comprising a receiving imaging base plate and an X-ray machine arranged on a fixed frame;

[0009] The receiving imaging base plate is driven by a translation device to move linearly in any direction parallel to the plane where the receiving imaging base plate is located;

[0010] The X-ray machine is driven to rotate by a steering power device.

[0011] Preferably, a hook rack is provided on the top of the fixing frame.

[0012] Preferably, walking rollers are installed on the upper part of the fixing frame.

[0013] Preferably, the fixed frame is equipped with a turning frame driven by a turning power device, the receiving imaging base plate and the translation device are arranged at the upper end of the turning frame, and the X-ray machine and the steering power device are arranged at the lower end of the turning frame.

[0014] Preferably, a movable frame driven by a telescopic assembly to move linearly is provided on the fixed frame, and the flip frame and the flip power device are installed on the movable frame.

[0015] Preferably, the flip frame is a telescopic structure, and the flip frame is telescopically adjusted to adjust the distance between the receiving imaging base plate and the X-ray machine.

[0016] Preferably, the flip frame end is rotatably connected to a guide frame, the guide frame is driven to rotate by a rotary power assembly, and the receiving imaging base plate is slidably connected to the guide frame.

[0017] Preferably, the flip frame is fixedly connected to a guide frame, an inner frame driven by a translation device is linearly slidably connected to the guide frame, and the imaging receiving base plate is rotatably connected to the inner frame by a rotating assembly.

[0018] The utility model has the following beneficial effects:

[0019] The receiving imaging base plate is driven by a translation device to move in a straight line parallel to the irradiation surface of the receiving imaging base plate, and the relative position of the receiving imaging base plate in the direction of its irradiation surface can be adjusted, thereby expanding the detection range;

[0020] Alternatively, the receiving imaging base plate may be designed to be smaller to facilitate reduction of the overall width, while the receiving imaging base plate can be moved when needed without reducing the use effect.

[0021] During this process, the X-ray machine follows the steering and aligns with the receiving imaging base plate after the adjusted position. BRIEF DESCRIPTION OF THE DRAWINGS
