Ring main unit circuit breaker shaft welding detection device

Abstract

The invention discloses a ring main unit circuit breaker shaft welding detection device which comprises a first support and a second support, the first support and the second support are movably connected, a shaft fixing part is connected with the first support, a sliding rail is arranged on the second support, multiple sets of deviation detection parts are arranged, a linkage moving mechanism is arranged between the deviation detection parts and the sliding rail and used for associating movement of the deviation detection parts with rotation of the circuit breaker shaft, according to the ring main unit circuit breaker shaft welding detection device, the circuit breaker shaft is fixed through the arrangement of the shaft fixing part, then deviation detection is conducted through the deviation detection parts, and in the detection process, under the action of the linkage moving mechanism, the deviation detection parts can move in the axial direction of the circuit breaker shaft, the movement is related to rotation of the circuit breaker shaft, continuous detection is achieved, comprehensive automatic detection is achieved, the contingency of single-point detection is avoided, and due to the fact that the planetary reduction gear mechanism can enlarge the output stroke, observation is more convenient.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a shaft welding detection device for a circuit breaker of a ring main unit. Background technique [0002] There is a common problem in the assembly of the circuit breaker shaft, which is mainly the overtravel difference between the AC two phases of the circuit breaker shaft. The main reason for the overtravel difference is the assembly gap and the deformation of the large shaft, because the large shaft will be welded Parts, therefore, have local or overall deformation, so welding inspection is required after the circuit breaker is welded and before assembly, so as to determine whether the large shaft is deformed, and the existing main way to detect the deformation of the circuit breaker shaft is to detect the diameter, However, this detection method cannot judge the specific deformation method very well, and this method can only detect a single point, and the efficien...
