Problems solved by technology

[0005] 1 The whole process consumes more manpower and time
[0006] 2 If the rotating post insulator is a little careless, it will damage the porcelain parts
[0007] 3 Flaw detection personnel are prone to fatigue at work, the continuity of flaw detection cannot be guaranteed, and it is difficult to locate bottom defects
[0009] Such a technical solution seems to be able to detect online, but its disadvantage is that it cannot detect the post insulators that are not in use at all, especially for the newly purchased post insulators.
If it is necessary to erect the post insulator for detection, it will take more time

Embodiment Construction

[0036] Such as figure 1 , figure 2 A post insulator flaw detection device is shown, which includes three functional parts: a load-bearing structure, a lifting structure, and a rotating structure. In order to improve the overall strength, all structures are made of titanium alloy, so that the overall weight of the present invention is only 9KG, and the lifting weight can reach 150KG, and it has good rigidity and no deformation. Wherein the load-bearing structure is a frame surrounded by the underframe crosspiece 2 and the underframe longitudinal piece 1 . Under normal circumstances, two base frame cross members 2 and two base frame longitudinal members 1 can form a frame. However, for the case where heavy post insulators need to be detected, additional underframe crosspieces 2 may also be provided. The number of additionally provided underframe crosspieces 2 is not limited, but the rotating structure cannot be affected. The lifting mechanism is installed on two underframe c...

Abstract

The invention aims at providing a post insulator flaw inspection device and a usage method thereof. The post insulator inspection device is mainly used for reducing the possibility of post insulator damage in inspection, can improve the inspection efficiency and also can be used by being mutually matched with equipment in the prior art. For achieving the purposes, the post insulator inspection device comprises three functional parts including a bearing structure, a lifting structure and a rotating structure; the bearing structure adopts a framework enclosed by two underframe transverse guards and underframe vertical guards; the lifting structure is installed on the underframe transverse guards and comprises screw rods which penetrate through the underframe transverse guards and are in threaded connection with the underframe transverse guards, the bottoms of the screw rods are fixed on supporting strips, and the tops of the screw rods are provided with rotating hand wheels; the rotating structure comprises a rotating structure body and a guiding structure body. Through the arrangement, the post insulator inspection device has the advantages of being capable of being mutually matched with the various inspection equipment in the prior art and achieving inspection under various severe environments.

Description

technical field [0001] The invention relates to a power detection device, in particular to a post insulator flaw detection device and a using method thereof. Background technique [0002] Post insulators are special insulation controls that can play an important role in overhead transmission lines. Post insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to ground. Failure, otherwise the use effect of the post insulator will be weakened, and the service life and operating life of the entire line will be damaged. [0003] Therefore, in order to ensure the use effect of the post insulator, it is necessary to test the post insulator before using it. In the prior art, in the substation, since the post insulators are arranged side by side and placed flat after they arrive, the workers need to remove the post insulators at a distance of 100 mm and use wooden blocks to cover them when performing ultrasonic ...
