Description

Technical Field

[0001] This invention relates to the field of ship hull production and processing technology, specifically to a hull surface quality inspection device used in the production of segmented hulls. Background Technology

[0002] The hull (commonly known as the "shell" or "hull") is composed of a series of plates and a frame (referred to as the "plate frame"). The plates and frame are interconnected and mutually supportive. The frame is the supporting component of the hull, increasing both the strength and rigidity of the hull plates and enhancing their resistance to instability. The hull consists of components such as the keel, side keels, keel reinforcements, ribs, bowposts, and sternposts. Due to the complexity of the hull structure, it is usually constructed in sections and then welded together sequentially. Therefore, it is necessary to inspect the surface quality of the hull to ensure the overall quality of the hull after welding.

[0003] A search revealed that application number CN202222521751.0 discloses a device for inspecting the surface quality of a ship's hull, including a mounting base. An adjustment mechanism is connected above the mounting base, and a protective workbench is connected above the adjustment mechanism. The device first uses a clamp to fix a hull model drawing board to a connecting plate. The operator then carries the connecting plate and climbs onto the protective workbench, attaching a collar to an L-shaped rod to fix the connecting plate to the workbench. When a location on the hull surface is found to be substandard or has an unacceptable paint thickness, the operator manually pulls the connecting plate, causing the elastic rope to stretch. A recording pen is then pulled out from inside the connecting plate and used to mark the corresponding location on the hull model drawing board for subsequent repair. However, in practical use, this device requires manual inspection, resulting in low efficiency and inaccurate results. Furthermore, existing inspection equipment suffers from problems such as difficulty or inconvenience in adjusting the inspection position during the inspection process. Summary of the Invention

[0029] The testing platform 3 is fixedly welded to the base of the movable frame 2. The testing mechanism is mounted on the posture adjustment mechanism, which is fixed to the base of the movable frame 2 and faces the rear. The posture adjustment mechanism can adjust the position of the testing mechanism in the front-back direction and the vertical direction. The operating mechanism is mounted on the testing platform 3 and extends to the bottom of the testing platform 3 to connect with the posture adjustment mechanism. The control and display mechanism is mounted on the testing platform 3 and is connected to the testing mechanism via a wireless signal for control and display.

[0030] As a further improvement to this embodiment, the detection mechanism includes a marking nozzle 4 connected to the posture adjustment mechanism and detection probes 5 distributed around the marking nozzle 4. The marking nozzle 4 and the detection probes 5 are connected to the control and display mechanism via wireless signals. The marking nozzle 4 is used to mark areas with defects on the hull surface, so that repair personnel can quickly locate the defects. The detection probes 5 are evenly distributed around the marking nozzle 4, and are used to detect the hull surface quality. In this embodiment, the detection probes 5 can be infrared detectors.

[0031] As a further improvement of this embodiment, the posture adjustment mechanism includes a horizontal adjustment component that is horizontally arranged on the base 2 of the movable frame and connected to the operating mechanism, a height adjustment component arranged on the horizontal adjustment component, a marking nozzle 4 and a detection probe 5 connected to the height adjustment component.

[0032] Furthermore, the horizontal adjustment assembly includes a support base 6 horizontally disposed on the base 2 of the movable frame, a horizontal adjustment screw 7 horizontally disposed on the support base 6, and a first conical friction wheel 8 coaxially connected to the front end of the horizontal adjustment screw 7 and connected to the operating mechanism. The height adjustment assembly is slidably mounted on the support base 6 and its bottom is connected to the horizontal adjustment screw 7. The support base 6 is distributed along the front-rear direction and extends out of the base 2 of the movable frame. The horizontal adjustment screw 7 is mounted on the support base 6 through a bearing and its front end extends out of the support base 6. The first conical friction wheel 8 is coaxially connected to this front end. The support base 6 serves to support the height adjustment assembly and provide horizontal guidance.

[0034] As a further improvement of this embodiment, the operating mechanism includes a rotating rod 15 connected to the base of the movable frame 2 and the detection platform 3 via a bearing and with its upper end exposed above the detection platform 3; a connecting sliding groove 16 opened on the lower part of the rotating rod 15; a double-sided friction conical turntable 17 slidably mounted on the connecting sliding groove 16; and an operating component coaxially connected to the rotating rod 15 and with its bottom rotatably connected to the double-sided friction conical turntable 17. Under the control of the operating component, the double-sided friction conical turntable 17 can switch between the first conical friction wheel 8 and the fourth conical friction wheel 14. A first rotating knob 19 is connected to the top of the rotating rod 15. The connecting sliding groove 16 acts as a spline groove, enabling the rotating rod 15 to drive the double-sided friction conical turntable 17 to rotate, and also providing guidance for the double-sided friction conical turntable 17 to slide up and down. Under the operation and control of the operating component, the lower friction surface of the double-sided friction conical turntable 17 can make frictional contact with the first conical friction wheel 8, and the upper friction surface of the double-sided friction conical turntable 17 can make frictional contact with the fourth conical friction wheel 14.

[0035] Furthermore, the operating assembly includes a sleeve 20 mounted on the rotating rod 15 via bearings. The top of the sleeve 20 is located above the detection platform 3 and connected to a second rotating knob 22. A threaded groove 23 is provided on the outer wall of the sleeve 20, and a connecting ring block 24 is mounted on the threaded groove 23. A connecting rod 25 is provided at the bottom of the connecting ring block 24, which is rotatably connected to the double-sided friction conical turntable 17.

Four connecting rods 25 are provided, corresponding to the bottom of the connecting ring block 24 in four directions: front, back, left, and right.

[0036] Furthermore, the upper surface of the double-sided friction conical turntable 17 is provided with an annular groove 26, and a connecting block 27 is provided in the annular groove 26 to slide relative to the annular groove 26.

The control switch 21 is used to turn the marking nozzle 4 on or off.

[0038] Working principle and usage process of this invention:

[0039] The operator moves the mobile inspection frame 1 along the fore-and-aft direction of the hull, with the rear of the mobile inspection frame 1 facing the hull surface. During use, the operator rotates the first rotation knob 19 on the rotating rod 15, which drives the first conical friction wheel 8 to rotate via the double-sided friction conical turntable 17. This causes the horizontal adjusting screw 7 to move the support frame 9 along the fore-and-aft direction, adjusting the distance between the marking nozzle 4 and the inspection probe 5 and the hull. Then, the inspection probe 5 begins to perform quality inspection on the hull surface. After inspecting the current area, the operator rotates the second rotation knob 22, causing the connecting ring block 24 to move upwards. This, via the connecting rod 25, drives the double-sided friction conical turntable 17 along the connecting slide... The moving slot 16 moves upward, causing the double-sided friction conical turntable 17 to disengage from the first conical friction wheel 8 and make frictional contact with the fourth conical friction wheel 14. Then, the first rotation knob 19 is rotated again, causing the height adjustment screw 10 to rotate through the double-sided friction conical turntable 17, the fourth conical friction wheel 14, the third conical friction wheel 13, and the second conical friction wheel 12, adjusting the height of the marking nozzle 4 and the detection probe 5, so that the marking nozzle 4 and the detection probe 5 move to the next area to be inspected on the surface of the ship for new inspection. During the inspection process, if a quality defect occurs, the marking nozzle 4 is turned on by the control switch 21 to mark the location.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely prisms of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
