Description

Technical Field

[0001] This utility model relates to the field of shell inspection technology, specifically a ship booster shell inspection device. Background Technology

[0002] The outer shell of a ship's booster refers to the external structure that encloses and protects the ship's booster (such as the propeller, propeller, etc.). Its main function is to ensure that the booster is protected from the influence of the external environment during operation, while improving propulsion efficiency and structural stability.

[0003] The external dimensional inspection of the ship booster shell is a fundamental part of the entire inspection process. Common inspection methods mainly utilize 3D scanning. However, during the inspection process, the shell needs to be placed inside the inspection chamber. In order to ensure the accuracy of the 3D scan, the shell angle needs to be adjusted multiple times, and loading and unloading operations are also required. The overall operation steps are relatively cumbersome and cannot form an effective assembly line inspection, resulting in low overall inspection efficiency. Utility Model Content

A sprocket is rotatably connected inside the conveying frame. The sprocket is connected via a pair of conveying chains. Carrier plates are fixed at equal intervals between the conveying chains. A rotating plate is rotatably connected to the carrier plate. A positioning component for fixing the booster shell is provided at the upper end of the rotating plate.

[0018] Please see Figure 1-4 This utility model provides a technical solution: including a conveying frame 1 and a scanning frame 4. The scanning frame 4 is fixed at the middle position of the upper end of the conveying frame 1. A three-dimensional scanning head 41 is installed on the inner side wall of the scanning frame 4. An alarm 42 is fixed at the upper end of the scanning frame 4. A control box 43 is fixed on the outer side of the scanning frame 4. A sprocket 11 is rotatably connected inside the conveying frame 1. The sprocket 11 is connected by a pair of conveying chains 12. A support plate 13 is fixed inside the conveying frame 1. The upper end of the support plate 13 is connected to the conveying chain 12. Carrier plates 2 are fixed at equal intervals between the conveying chains 12. A rotating plate 3 is rotatably connected to the carrier plate 2. A positioning component for fixing the booster shell is provided at the upper end of the rotating plate 3. An inner side plate 5 is fixed inside the conveying frame 1. A rotating component is provided on the inner side plate 5 and below the scanning frame 4.

[0019] The rotating assembly includes a docking plate 52 and a docking block 31. The docking block 31 is fixed to the bottom of the rotating plate 3. The bottom of the docking block 31 passes through the carrier plate 2 and is rotatably connected to the carrier plate 2. A docking groove 32 is provided at the bottom of the docking block 31, and a positioning sensor is fixed in the docking groove 32. The docking plate 52 is rotatably connected to the upper end of the inner side plate 5. The rotating plate 3 is aligned with the docking groove 32 and inserted into the docking groove 32. A servo motor 51 that drives the docking plate 52 to rotate is fixed in the inner side plate 5.

[0020] The positioning component includes a clamping block 37, which is slidably connected to the upper end of the rotating plate 3 and is arranged in a circumferential array. A groove 38 is provided in the rotating plate 3 at a position corresponding to the clamping block 37. A threaded rod 33 is rotatably connected in the groove 38. The bottom of the clamping block 37 is slidably connected in the groove 38. The threaded rod 33 passes through the clamping block 37 and is threadedly connected to the clamping block 37. A central groove 34 is provided at the center position of the rotating plate 3. A drive bevel gear 36 is rotatably connected in the central groove 34. A drive motor that drives the drive bevel gear 36 to rotate is installed at the bottom of the central groove 34. The threaded rod 33 is located at one end close to the other end in the central groove 34 and is fixed with a transmission bevel gear 35. The transmission bevel gear 35 meshes with the drive bevel gear 36.

[0021] Working Principle: First, connect the entire device to an external power source. Driven by the rotation of sprocket 11 and the transmission of conveyor chain 12, the carrier plate 2 continuously passes through the scanning frame 4. At this time, the ship booster shell is loaded onto the rotating plate 3, synchronously driving the ship booster shell into the scanning frame 4 for three-dimensional scanning. Simultaneously, as it enters the scanning frame 4, the rotation of the rotating plate 3 causes the ship booster shell to rotate, achieving accurate three-dimensional scanning. Throughout the process, loading and unloading are only required at both ends, thus greatly improving detection efficiency. When fixing the ship booster shell, place it at the center of the rotating plate 3, and simultaneously insert the clamping block 37 into the ship booster... Inside the outer shell of the booster, the sliding of the clamping block 37 supports and fixes the inner cavity of the booster shell. In this process, the drive motor drives the drive bevel gear 36 to rotate, and the transmission bevel gear 35 drives the threaded rod 33 to rotate, thereby driving the clamping block 37 to slide. When the rotating plate 3 is driven to rotate, the docking block 31 at the bottom of the rotating plate 3 moves to the position aligned with the docking plate 52 as the carrier plate 2 slides. At this time, the docking plate 52 will be inserted into the docking groove 32. Therefore, the rotation of the docking plate 52 will drive the docking block 31 to rotate synchronously, thereby driving the rotating plate 3 to rotate. When the opening of the docking groove 32 is aligned with the direction of movement of the carrier plate 2, it can slide normally without any impact.
