A rotating shaft is fixed to the end of each rotating roller and rotatably penetrates the vertical plate. The ends of the multiple rotating shafts located outside the vertical plates are connected by a synchronous belt drive. A horizontally arranged base plate is fixedly disposed at the bottom between the two vertical plates. A drive gear is rotatably disposed at the middle end of the base plate. Two symmetrically arranged toothed plates mesh with the drive gear. The two toothed plates are diagonally arranged, with their ends away from the drive gear penetrating the vertical plate. A movable seat is fixedly disposed at the end of each toothed plate penetrating the vertical plate. A vertically arranged movable plate is movably inserted into the movable seat. A housing is fixedly disposed on the top of the movable plate. A visual detection head is mounted on the end of the housing near the vertical plate. The visual detection head is externally connected to a display via a data cable.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figure 1-4As shown, this utility model provides a visual inspection device for the inner wall of a steel pipe, including two vertically symmetrically arranged upright plates 1. Each upright plate 1 has a placement groove 11 at its top, and a recess 12 inside the placement groove 11. Rotating rollers 13, arranged in a ring, are rotatably mounted within the recess 12. The surface of the rotating rollers 13 can be textured with friction, or it can be a frosted surface or a rubber material. A rotating shaft 14 is fixed to the end of each rotating roller 13 and rotates through the upright plate 1. The ends of the multiple rotating shafts 14 located outside the upright plates 1 are connected by a synchronous belt 15, which is used in conjunction with a synchronous pulley to ensure synchronous rotation among the multiple rotating shafts 14. The synchronous belt 15 and the synchronous pulley adopt a toothed synchronous belt 15 and synchronous pulley to eliminate the lag in transmission. The bottom of the two vertical plates 1 is fixed together with a horizontally arranged base plate 2. The middle end of the base plate 2 is rotatably provided with a drive gear 21. Two symmetrically arranged toothed plates 23 are meshed on the drive gear 21. The two toothed plates 23 are diagonally distributed and the end away from the drive gear 21 passes through the vertical plate 1. A movable seat 3 is fixedly provided at the end of the toothed plate 23 that passes through the vertical plate 1. A vertically arranged movable plate 31 is movably inserted on the movable seat 3. A housing 32 is fixedly provided on the top of the movable plate 31. A vision detection head 33 is installed at the end of the housing 32 near the vertical plate 1. The vision detection head 33 is connected to an external display through a data cable 34.

[0017] A connecting shaft 16 is fixedly connected between the rotating shafts 14 on the two upright plates 1. A first motor 17 is installed on one of the upright plates 1 below the connecting shaft 16. The output end of the first motor 17 is connected to the connecting shaft 16 through two meshing transmission gears 18. The first motor 17 mainly provides power for the rotation of the rotating shaft 14, thereby causing the rotating roller 13 to rotate and drive the steel pipe placed on the placement groove 11 to rotate.

[0018] A bracket is fixedly installed on the base plate 2 near the drive gear 21, and a second motor 22 is installed on the bracket. The output end of the second motor 22 is coaxially fixed at the center of the drive gear 21. The second motor 22 mainly provides power for the rotation of the drive gear 21, so that the drive gear 21 drives the two tooth plates 23 to move towards each other or away from each other at the same time, thereby controlling the visual detection head 33 on the moving seat 3 to extend into the steel pipe for detection.

[0019] The toothed plate 23 is fixedly provided with a limiting strip 25 on its side wall and the limiting strip 25 moves through the vertical plate 1. The setting of the limiting strip 25 can ensure the stable movement of the toothed plate 23 and prevent deviation. The two ends of the side wall of the movable seat 3 are fixedly provided with long rods 24. The end of the long rod 24 away from the movable seat 3 passes through the vertical plate 1. The long rod 24 mainly provides further support for the horizontal movement of the movable seat 3, so that it can move stably.

[0020] A vertically mounted electric push rod 35 is fixedly installed on the upper surface of the movable base 3 near the movable plate 31. The output end of the electric push rod 35 is coaxially fixed on the movable plate 31. The electric push rod 35 can easily control the vertical height of the vision detection head 33, allowing the vision detection head 33 to be closer to the inner wall of the steel pipe, making its detection clearer.

[0021] Working principle: During use, the operator places the steel pipe to be inspected into the placement slot 11. Then, the operator can start the first motor 17 and the second motor 22. The second motor 22 drives the drive gear 21 to rotate, causing the meshing toothed plates 23 on the drive gear 21 to move towards each other. The movable seats 3 fixed at the ends of the two toothed plates 23 will move towards the upright plate 1. The visual detection head 33 fixed on the upright plate 1 will gradually extend into the steel pipe. The image detected by the visual detection head 33 will be transmitted to an external display via the data cable 34 for direct observation by the operator. Meanwhile, the first motor 17 will drive the connecting shaft 16 to rotate, and the connecting shaft 16 will simultaneously drive the rotating shafts 14 on the two upright plates 1 to rotate. At the same time, the multiple rotating shafts 14 are connected by a synchronous belt 15. At this time, the multiple rotating rollers 13 will rotate synchronously, driving the placed steel pipe to rotate. This increases the detection range of the inside of the steel pipe within the visual detection head 33, allowing the visual detection head 33 to detect it more comprehensively. During the detection process, the staff only needs to drive the observation display, without the need for additional physical operation, which greatly reduces the workload and physical intensity of the staff.
