Problems solved by technology
[0003] The technical problem to be solved by the present invention is that the rotation structure of the currently commonly used pipe weld inspection mirror is complex, which cannot satisfy the omni-directional inspection of the inner wall of the pipe. When the pipe with a large inner diameter is detected, the lens is not clear. , a pipeline weld inspection mirror capable of detecting 360° circumferential welds on the inner wall of the pipeline

Embodiment Construction
[0010] like Figure 1 to Figure 2 As shown, the present invention includes a fixed part 1 and a rotating part 2 sleeved on the fixed part 1 with the fixed part 1. A motor 3 is arranged in the fixed part 1, and the output shaft of the motor 3 is connected with a pinion 4. Inside the rotating part 2 An internal gear 5 is provided, and the pinion 4 meshes with the internal gear 5; a lens 6 is provided on the side wall of the rotating part 2, and a headlight 7 is provided at the front end.
[0011] A side light 8 is also provided on the side wall of the rotating member 2, and the side light 8 can clearly observe the inner wall around the pipe.
[0012] Balls are arranged between the protective cover 9 and the outer wall of the fixing part 1, and the balls are arranged in the groove 10 of the outer wall of the fixing part 1. The protective sleeve 9 is fixedly connected with the rotating part 2 , and the existence of the protective sleeve and the ball reduces the friction between t...

The invention discloses a pipeline weld detection mirror, and particularly relates to a pipeline weld detection mirror for detecting an inner wall of a pipeline. Technical problems that a rotating structure of an existing pipeline weld detection mirror is complex; all-dimensional detection of the inner wall of the pipeline can't be satisfied; and the lens isn't clear when the diameter of the pipeline to be detected is large need to be overcome. The pipeline weld detection mirror comprises a fixed piece and a rotating piece sleeving the fixed piece, wherein the fixed piece is internally provided with a motor, the output shaft of which is connected to a small gear; and a rotating piece is internally provided with an inner gear, which engages with the small gear; the side wall of the rotating piece is provided with a lens; and the front end of the rotating piece is provided with a front light. By using the structure above, the pipeline weld detection mirror is simple in structure and flexible and convenient to use, can detect the circumferential weld in the pipeline through 360 degrees, is small in friction, and can accurately detect the weld of the inner wall when the inner diameter of the pipeline to be detected is large.
Description
technical field [0001] The invention relates to a detection mirror, in particular to a pipeline weld seam detection mirror for detecting the inner wall of a pipeline. Background technique [0002] At present, inspection mirrors are used when inspecting the interior of the pipeline, and the inspection mirror needs to be deep into the pipeline. The commonly used inspection mirrors cannot be rotated or rotated difficultly, and the structure is complex, which cannot meet the all-round inspection of the inner wall of the pipeline, and the detection light is directly illuminated. When the inner diameter of the inspection pipe is large, the light reaching the pipe wall is weak, and the lens is not clear, which cannot accurately reflect the welding condition of the inner wall of the pipe, and the work efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is that the currently commonly used pipe weld inspection mirror has ...
