Description

Technical Field

[0001] This utility model relates to the field of marine weld inspection technology, and more specifically, to a marine weld inspection positioning device. Background Technology

[0002] Ships are man-made transportation vehicles that can navigate or anchor on water and carry out transportation or operations. Pipes inside ships are mainly connected and fixed by welding. After the welding is completed, testing devices are usually used to inspect the quality of the welds on the pipes to determine whether the quality of the welds is up to standard.

[0003] However, existing technologies have some problems: In order to ensure the stability of the pipe fittings during inspection, existing inspection devices are equipped with clamping and positioning mechanisms to facilitate the positioning of the pipe fittings. However, in actual use, workers often need to inspect different positions of the weld seam of the pipe fittings, which requires frequent movement of the inspection head or adjustment of the positioning angle of the pipe fittings. This is cumbersome and reduces the inspection efficiency. Therefore, we propose a marine weld seam inspection and positioning device. Utility Model Content

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0020] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0022] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0023] like Figures 1-4 As shown, a marine weld inspection and positioning device includes a base 1. Vertical plates 2 are fixedly installed on both sides of the top of the base 1. A cylinder 3 is rotatably connected to the vertical plates 2. A worm gear 4 is fixedly connected to the other end of the cylinder 3. The worm gear 4 is also connected to the base 1 through a drive assembly. The worm gear 4 can drive the cylinder 3 to rotate through the drive assembly. A clamping assembly is provided inside the cylinder 3 for clamping and positioning pipe fittings. An inspection assembly is provided on the base 1 for inspecting the weld seams of the pipe fittings.

[0024] In use, the staff places the marine pipe fitting inside the cylinder 3 and clamps and positions the pipe fitting using the clamping assembly. Then, the weld seam on the surface of the pipe fitting can be inspected using the detection assembly. When it is necessary to inspect different positions of the weld seam, the staff can use the drive assembly to make the worm gear 4 drive the cylinder 3 and the clamped pipe fitting to rotate, which facilitates the inspection of different positions of the weld seam, making the inspection work more convenient and improving work efficiency.

[0025] The aforementioned marine weld seam inspection and positioning device includes a drive component comprising a brake motor 5, which is fixedly mounted on a base 1. The output shaft of the brake motor 5 is connected to a rotating shaft 6 via a coupling. A vertical plate 7 is fixedly mounted on the base 1, and a round shaft 8 is rotatably connected to the vertical plate 7. Worms 9 are fixedly connected to both the round shaft 8 and the rotating shaft 6, and the worms 9 are meshed with a worm wheel 4.

[0026] By activating the brake motor 5, the rotating shaft 6 can drive the worm gear 9 connected to it to rotate, thereby causing the worm wheel 4 to rotate. In turn, the worm wheel 4 can drive the cylinder 3 and the clamped pipe to rotate, which facilitates the inspection of different positions of the pipe weld and makes the inspection work easier.

[0027] The above-mentioned marine weld inspection and positioning device has a drive wheel 10 fixedly sleeved on the outer surface of the rotating shaft 6, a driven wheel 11 fixedly sleeved on the outer surface of the round shaft 8, and a belt 12 connecting the driven wheel 11 and the drive wheel 10.

[0028] Through the design of belt 12, when the rotating shaft 6 drives the driving wheel 10 to rotate, the driven wheel 11 and the round shaft 8 can be driven to rotate together through belt 12, so that the two worm gears 9 can rotate together, ensuring the synchronicity of the rotation of the pipe fittings on both sides of the weld and avoiding damage to the weld caused by asynchronous rotation.

[0029] The above-mentioned marine weld inspection and positioning device includes a clamping assembly comprising a guide rod 13, which is fixedly installed on the inner wall of a cylinder 3. Both ends of the outer surface of the guide rod 13 are movably sleeved with clamping plates 14. A bidirectional threaded rod 15 is rotatably connected to the cylinder 3, and the two clamping plates 14 are respectively threaded onto both sides of the outer surface of the bidirectional threaded rod 15.

[0030] By rotating the bidirectional threaded rod 15, the two clamping plates 14 can move towards or away from each other under the guidance of the guide rod 13. When the two clamping plates 14 move towards each other, they can clamp and position the pipes inside the cylinder 3.

[0031] The above-mentioned marine weld inspection and positioning device includes a detection component including a slide rail 16, which is fixedly installed on a base 1. An electric slide 17 is slidably connected to the slide rail 16, and an electric push rod 18 is fixedly installed on the electric slide 17. The telescopic end of the electric push rod 18 passes through the electric slide 17 and is fixedly connected to a detection head 19.

[0032] When inspecting the weld, the operator controls the electric slide 17 to slide to the corresponding position of the weld, and then adjusts the distance between the inspection head 19 and the weld by the electric push rod 18. After the adjustment is completed, the inspection can be carried out through the inspection head 19. It should be noted that the inspection head 19 is connected to the detector, and the inspection method is existing technology, which will not be described in detail here.

[0033] The aforementioned marine weld inspection and positioning device has a gasket 20 fixedly installed on the surface of the clamping plate 14, and the surface of the gasket 20 is provided with anti-slip texture.

[0034] The gasket 20 may be made of rubber and have anti-slip texture on its surface, thereby improving the clamping effect on the pipe fitting.

[0035] Working principle and usage process of this utility model:

[0036] First, the worker places the pipe fitting inside the cylinder 3, then rotates the double-threaded rod 15, causing the two clamping plates 14 to move towards each other under the guidance of the guide rod 13. When the two clamping plates 14 move towards each other, they can clamp and position the pipe fitting inside the cylinder 3. Then, the electric slide 17 can be controlled to slide to the corresponding position of the weld. The distance between the detection head 19 and the weld is then adjusted using the electric push rod 18. After adjustment, the detection head 19 can be used for inspection. When other positions of the weld need to be inspected, the worker can activate the brake motor 5. Due to the operation of the brake motor 5... The rotating shaft 6 can drive the worm gear 9 and the driving wheel 10 connected to it to rotate. Through the design of the belt 12, when the rotating shaft 6 drives the driving wheel 10 to rotate, the driven wheel 11 and the round shaft 8 can be driven to rotate together through the belt 12. This allows the two worm gears 9 to rotate together, which in turn allows the worm wheel 4 to rotate. In turn, the worm wheel 4 can drive the cylinder 3 and the clamped pipe to rotate, ensuring the synchronicity of the rotation of the pipe on both sides of the weld and avoiding damage to the weld caused by asynchronous rotation. This facilitates the inspection of different positions of the pipe weld, making the inspection work more convenient and improving the inspection efficiency.

[0037] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
