Description

Technical Field

[0001] The utility model relates to the technical field of crack detectors, in particular to a crack detector capable of accommodating a detection head. Background Art

[0002] The function of a crack detector is to detect cracks on the outer surface of a material, helping engineers quickly locate the crack location. The crack detector consists of a light source, a lens, an image processing system, and a display screen. The light source is the core component. The light emitted by the light source reflects the shape of the crack onto the lens, thereby detecting cracks on the outer surface of the material. There are many different crack detectors on the market.

[0003] However, general crack detectors are not convenient for automatically moving the detection head. Therefore, when the area of the material to be detected is large, manual pushing of the detector is likely to result in missed detections. It is also inconvenient to store the detection head. Therefore, when the detection head is not needed, it is easy for the detection head to be accidentally bumped during placement, and the detection head cannot be protected. It is also inconvenient to orderly wind up the wiring harness of the crack detector. Therefore, when the crack detector is moved to a distant location, the wiring harness is likely to become messy and need to be manually organized. Therefore, we propose a crack detector with a storable detection head to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-5 The utility model provides a technical solution: a crack detector that can accommodate a detection head, including a box body 1, a first motor 2, a rotating rod 3, a long sliding rod 4, a slide 5, a fixed groove frame 6, a second motor 7, an eccentric wheel 8, a groove seat 9, a telescopic rod 10, a detection head body 11, a connecting line 12, a winding roller 13, a groove wheel 14, a fixed rod 15, a rotating wheel 16 and a third motor 17.

[0029] Example 1: Please refer to Figure 1-Figure 5 The existing crack detector is not convenient for automatically moving the detection head. Therefore, when the area of the material to be detected is large, manual pushing of the detector is prone to missed detections. In order to solve this technical problem, this embodiment discloses the following technical content.

[0030] A crack detector that can accommodate a detection head includes a box body 1, the left side of the lower end of the box body 1 is fixedly connected to a first motor 2, and the upper end of the first motor 2 is fixedly connected to a rotating rod 3, and the outer side of the upper end of the rotating rod 3 is rotatably connected to the inner left end of a long slide rod 4, the outer side of the right end of the long slide rod 4 is slidably connected to the inner upper end of a slide 5, and the outer slot of the lower end of the slide 5 is connected to the box body 1, and the upper end of the slide 5 is fixedly connected to a fixed slot frame 6.

[0031] When it is necessary to move the detection head, the first motor 2 is started to drive the rotating rod 3 fixedly connected to the upper end of the first motor 2 to rotate, so that the outer side of the left end of the rotating rod 3 rotates inside the left end of the long slide bar 4. When it is necessary to move the detection head backward, the first motor 2 is controlled to drive the rotating rod 3 to rotate backward. At this time, the outer side of the right end of the long slide bar 4 slides to the right inside the upper end of the slide 5, driving the slide 5 to move backward on the outer side of the upper end of the box 1. When it is necessary to move the detection head forward, the first motor 2 is controlled to drive the rotating rod 3 to rotate forward. At this time, the outer side of the right end of the long slide bar 4 slides to the left inside the upper end of the slide 5, driving the slide 5 to move forward on the outer side of the upper end of the box 1. The position of the crack detector can be automatically moved to avoid the situation where the material area is large and the detection is missed.

[0032] Example 2: Please refer to Figure 1-Figure 5 The existing crack detector is not convenient for storing the detection head. Therefore, when the detection head is not needed, it is easy for the detection head to be accidentally bumped when placed, and the detection head cannot be protected. In order to solve this technical problem, this embodiment discloses the following technical content.

[0033] A crack detector that can accommodate a detection head includes a slide 5, the upper end of the slide 5 is fixedly connected to a fixed slot frame 6, and the inner slot of the fixed slot frame 6 is connected to a groove seat 9, and the inner slot of the front end of the groove seat 9 is connected to an eccentric wheel 8, the front end of the eccentric wheel 8 is fixedly connected to a second motor 7, and the lower end of the second motor 7 is fixedly connected to the fixed slot frame 6, and the lower end of the groove seat 9 is fixedly connected to a telescopic rod 10, a detection head body 11 is installed on the outer side of the upper end of the groove seat 9, and the right end of the detection head body 11 is fixedly connected to a connecting line 12, and the outer slot of the left end of the connecting line 12 is connected to the fixed slot frame 6.

At this time, the telescopic rod 10 fixedly connected to the lower end of the groove seat 9 shrinks downward to limit the groove seat 9. At the same time, the connecting line 12 fixedly connected to the right end of the detection head body 11 moves downward on the inner side of the right end of the fixed groove frame 6, which can automatically store the detection head of the crack detector and protect the detection head.

[0035] Example 3: Please refer to Figure 1-Figure 5 The existing crack detector is not convenient for orderly winding the wire harness of the crack detector. Therefore, when the crack detector is moved to a far position, the wire harness is likely to become messy and needs to be manually sorted.

[0037] When the wiring harness of the crack detector needs to be wound in an orderly manner, the third motor 17 is started to drive the fixed rod 15 to rotate. When the outer front end of the fixed rod 15 is connected to the groove wheel 14 by a slot, the groove wheel 14 is driven to rotate. When the groove wheel 14 rotates counterclockwise, the excess part of the wound connecting wire 12 on the outer side of the winding roller 13 fixedly connected to the front end of the groove wheel 14 is wound up. When the third motor 17 drives the rotating wheel 16 to continue to rotate, the outer left end of the rotating wheel 16 fixed to the front end of the fixed rod 15 is tightly fitted with the groove wheel 14. At this time, the groove wheel 14 stops driving to avoid the wiring harness from being wound too quickly and breaking. It can be wound automatically and orderly to prevent the wiring harness from being messy and affecting the use of the crack detector.
