Problems solved by technology

The traditional method can only detect the position of the clamp close to the iron tower
For the position of the connecting pipe with a large span and in the middle of the span, it is not easy for the operator to approach, and if there is already a problem inside the connecting pipe, the increased load due to the approach of the operator will increase the possibility of wire breakage
At the same time, the current scheme cannot be used for live work and there is no effective way to detect the position of the connecting pipe. This makes it difficult to detect the position of the connecting pipe currently in the middle of the gear distance, and in the long run it is easy to cause a huge safety hazard of disconnection

Abstract

The invention relates to an overhead power transmission line splicing sleeve live X-ray flaw detection device and method, and belongs to the field of line detection, the device mainly comprises a linelifting frame and a line detection base; the line lifting frame comprises a top plate; two ends of the top plate in the length direction are connected with first wheel carriers; a wire guide pulley is rotationally connected into the first wheel carrier, and a wire guide-in groove is formed in the first wheel carrier; the wire pulley is arranged at the upper end of the wire lead-in groove outlet;a second wheel carrier is connected below the first wheel carrier, and an X-ray machine pulley is rotatably connected in the second wheel carrier; a lower stay wire hole is formed in the top plate; alifting stay wire hole is formed in the first wheel carrier; an X-ray machine and an X-ray imaging plate are respectively arranged at two ends of the line detection base in the length direction of thebase; lifting hanging rings are arranged on the two sides of the detection base in the length direction of the base respectively. The flaw detection device is used for detecting the position of the splicing sleeve in the middle of the power transmission line, climbing of an operator is not needed, and meanwhile hot-line work can be achieved.

Description

technical field [0001] The disclosure belongs to the technical field of transmission line detection, and in particular relates to a live X-ray flaw detection device and method for an overhead transmission line connection pipe. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the development of society and economy, the inspection requirements of transmission lines are getting higher and higher. In order to improve the management level of transmission lines, the state detection and maintenance of transmission lines should be strengthened. The application of X-ray digital imaging detection technology to the state detection of power transmission lines provides a fast, visible and non-destructive detection method for live detection of power transmission line equipment. structural flaws. [0004] The inventor found that: the existing splicing pipe...
