Retractable CT (Computerized Tomography) measuring rod and measuring method thereof

Abstract

The invention discloses a retractable CT (Computerized Tomography) measuring rod and a measuring method thereof. The measuring rod comprises an outer rod body, a middle rod body and an inner rod body;a motor is fixed on a bottom surface at the interior of the outer rod body; a bevel gear I is fixed on an end part of an output shaft of the motor; the bevel gear I is meshed with a bevel gear II; the bevel gear II is fixedly sleeved on a middle end of a rotating shaft; both ends of the rotating shaft are rotatably connected with a bearing seat I; the bearing seat I is fixed on an inner wall of the outer rod body; a bevel gear III is fixed on an end part of the rotating shaft; the bevel gear III is meshed with a bevel gear IV; the bevel gear IV is fixedly sleeved on a bottom end of a lead screw; two ends of the lead screw are respectively and rotatably disposed on a bearing seat II; and the bearing seat II is further fixed on the inner wall of the outer rod body. According to the retractable CT (Computerized Tomography) measuring rod and the measuring method thereof disclosed by the invention, by disposing the lead screw, a lead screw sleeve, a guide rail, a roller, a pulley I, a pulley II, a pothook and a steel wire rope, the problems that the rods are easy to incline and low in retraction efficiency when the conventional CT measuring rods are spliced are solved.

Description

technical field [0001] The invention relates to the technical field of electric wire measurement, in particular to a telescopic CT measuring rod and a measuring method thereof. Background technique [0002] When carrying out a current flow in the substation, the ordinary measuring pole needs to be spliced ​​by multiple insulating rods, and the primary line of the current flow is hung to the busbar side and the line side of the current transformer in the power failure interval. Due to the high voltage level of 220kV to the ground Due to the long distance, the weight of the rod itself will inevitably tilt during the hooking process, and there is a risk of accidentally touching the adjacent live space, and the splicing efficiency is low, and the entire measuring rod is inconvenient to retract. Therefore, the present invention designs a telescopic CT measuring rod and Its measurement method to solve the above problems. Contents of the invention [0003] (1) Solved technical p...
