Description

Technical Field

[0001] The invention relates to the technical field of welding angle inspection tools, in particular to a welding angle measuring tool for ship hull construction. Background Art

[0002] Modern cruise ships are tourist-oriented, just like mobile hotels. Cruise ships can be divided into large cruise ships, medium cruise ships and small cruise ships according to their sizes. Section weight control is one of the weight risk points in the construction of cruise ships, and weld angle control is the core measure of section weight control. When welding the hull steel plates, employees generally follow the principle of "large rather than small", that is, the size of the weld angle should be as large as possible, but not too small. After the welding of the hull steel plates is completed, the size of the weld angle needs to be inspected with the help of a weld angle ruler.

[0003] The existing welding angle ruler needs to adjust the scale line before use. When measuring, it is difficult for the side of the welding angle ruler to be pressed against the two welded steel plates at the same time, and it is not easy to maintain stability, which affects the accuracy of the reading. In addition, the existing welding angle ruler cannot check the verticality of the two welded steel plates, and has great limitations in use. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-5 , a weld angle measuring tool for ship hull construction, comprising a first cross bar 1, a first rotating rod 2 is rotatably connected to one side of the first cross bar 1, a second cross bar 11 is arranged at one end of the first cross bar 1, a knob 3 is connected to one end of the first rotating rod 2, a disc 4 is arranged on the surface of the first rotating rod 2, and a rotating plate 7 is arranged at one side of the first rotating rod 2;

[0032] A fixed rod 5 is connected to one side of the disc 4, and round rods 6 are arranged at both ends of one side of the fixed rod 5. Rod grooves 13 cooperating with the round rod 6 are opened at the four corners of the rotating plate 7. When the knob 3 is held to rotate the disc 4, the fixed rod 5 and the round rod 6 rotate synchronously with the disc 4. Under the cooperation of the round rod 6 and the rod groove 13, the rotating plate 7 can be rotated by 90° at a time, that is, a single rotation of 90° of the panel 9 is realized. A second rotating rod 8 is connected to one side of the rotating plate 7, and the second rotating rod 8 is rotatably connected to the first cross bar 1, and one end of the second rotating rod 8 is fixedly connected to the panel 9. The four corners of the panel 9 are provided with An inspection part 10 is provided, and a clamping piece 34 is fixed on one side of the inspection part 10. A clamping groove 35 is opened on the surface of the panel 9 at the position corresponding to the clamping piece 34. The sizes of the four inspection parts 10 are different, and can be used to inspect welding angles of different sizes. In addition, the inspection parts 10 of different sizes can be replaced at any time. The clamping piece 34 is made of a plastic material with good toughness and strength, such as POM and nylon. The inspection part 10 can be fixed at the corner of the panel 9 by clamping the clamping piece 34 with the clamping groove 35. Conversely, the inspection part 10 can be disassembled by disengaging the clamping piece 34 from the clamping groove 35.

[0033] Reference Figure 5-6 A fixing mechanism is provided between the rotating plate 7 and the first cross bar 1, and the fixing mechanism includes a fixing frame 12, and an insertion rod 14 is provided through one end of the fixing frame 12. A plug rod 14 is symmetrically provided on the surface of the rotating plate 7 with plug holes 21 cooperating with the plug rod 14. By pulling one end of the plug rod 14 out of a currently inserted plug hole 21, the fixing of the rotating plate 7 and the panel 9 can be cancelled. Conversely, by inserting the plug rod 14 into the plug hole 21 directly opposite to it, the rotating plate 7 and the panel 9 can be fixed again to prevent the rotating plate 7 and the panel 9 from automatically rotating. A hole 18 is provided at one end of the fixing frame 12 at the position corresponding to the plug rod 14, and a handle 15 is fixed to one end of the plug rod 14, and a first spring 16 is sleeved on the surface of the plug rod 14 between the handle 15 and the fixing frame 12, and the plug rod 14 is slidably connected to the hole 18.

[0034] Reference Figure 6 A convex strip 19 is fixed to the inner side of the fixing frame 12, and a vertical rod 17 is fixed to the surface of the insertion rod 14. A card slot 20 cooperating with the convex strip 19 is opened at the upper end of the vertical rod 17. The card slot 20 is engaged with the convex strip 19, which can temporarily fix the position of the insertion rod 14 after the insertion hole 21 is pulled out.

[0035] Reference Figure 3 and Figure 5 A check rod 22 is provided at one end of the second cross bar 11, and a connecting rod 25 is fixed above the fixing frame 12. The check rod 22 and the second cross bar 11 are rotatably connected through a pin shaft 23. The outside of the pin shaft 23 is sleeved with a torsion spring located between the check rod 22 and the second cross bar 11, and a pointer 24 is fixed to the upper end of one side of the check rod 22. An angle measuring scale 26 is connected to one end of the connecting rod 25. After the extended check rod 22 is fixed, the center of the pointer 24 coincides with the center of the angle measuring scale 26, and the 0° scale line on the angle measuring scale 26 is located on the center line of the angle measuring scale 26.

[0036] Reference Figure 7-8 The first cross bar 1 is connected to the second cross bar 11 through an extension mechanism, which includes a receiving groove 27, a second spring 28 is arranged inside the receiving groove 27, and a buckle 29 is connected to one end of the second spring 28. A first bayonet 30 is provided on the surface of the second cross bar 11, and a second bayonet 31 is provided on the surface of the second cross bar 11 on one side of the first bayonet 30. The sizes of the first bayonet 30 and the second bayonet 31 are both adapted to the size of the buckle 29. After the two buckles 29 are engaged with the two second bayonet 31, the extended second cross bar 11 can be fixed.

[0037] Reference Figure 8 A limiting block 32 is fixed on the inner side of the second cross bar 11, and a limiting groove 33 is provided on the surface of the first cross bar 1 at the position corresponding to the limiting block 32. When the second cross bar 11 is pulled, the limiting block 32 slides inside the limiting groove 33, thereby limiting the second cross bar 11 and preventing the second cross bar 11 from separating from the first cross bar 1.

[0038] In the present invention, the sizes of the four inspection parts 10 are all different, and they can be used to inspect the welding angles of different sizes. Before the inspection, it is necessary to turn the inspection part 10 to be used to the position directly below the inspection rod 22 - first hold the handle 15, and pull one end of the insertion rod 14 out of the currently inserted insertion hole 21. At this time, the first spring 16 is stretched until the card slot 20 is engaged with the convex strip 19, thereby temporarily fixing the position of the insertion rod 14. This can cancel the fixation of the rotating plate 7 and the panel 9. Then, hold the knob 3 to rotate the disc 4, and the fixing rod 5 and the round rod 6 will move with the disc 4. The rotating plate 7 is rotated by 90° at a time, and the panel 9 is rotated by 90° at a time, until the inspection part 10 to be used is rotated to the bottom of the inspection rod 22, which is convenient for the subsequent inspection of the weld angle and the verticality inspection of the two hull steel plates where the weld angle is located. After the panel 9 is rotated, the handle 15 is pushed to disengage the slot 20 from the convex strip 19, so that the insertion rod 14 is inserted into the insertion hole 21 opposite to it. The first spring 16 plays a certain buffering role, and the rotating plate 7 and the panel 9 can be fixed again.

[0039] Then, only two adjacent edges of the panel 9 need to be abutted against the side edges of the two adjacent steel plates where the weld angle is located, and one of the inspection parts 10 can be used to inspect the weld angle to check whether the weld angle to be inspected can fit with the side edge outside the inspection part 10 of the specified size. During the inspection, the panel 9 can be kept stable, and the inspection method is simple and easy to operate;

[0040] After the inspection of the welding angle is completed, the verticality of the two adjacent hull steel plates where the welding angle is located can also be inspected. The inspection method is as follows: initially, the two clips 29 are engaged with the first clip openings 30, so that the inspection rod 22 will not cause obstruction to the contact between the two adjacent sides of the panel 9 and the side edges of the two adjacent steel plates where the welding angle is located. After the inspection of the welding angle is completed, the two clips 29 are first pressed into the receiving groove 27, during which the second spring 28 is compressed. Then, the second cross bar 11 is pulled, and the end faces of the two clips 29 slide against the inner wall of the second cross bar 11 until the second clip opening 31 moves to the position where the clips 29 are located. Under the elastic force of the second spring 28, the two clips 29 are able to engage with the two second clip openings 31, so that the extended second cross bar 11 can be fixed. In the process of pulling the second cross bar 11, the limit block 32 slides inside the limit groove 33, which limits the second cross bar 11 and prevents the second cross bar 11 from separating from the first cross bar 1.

[0041] After the extended inspection rod 22 is fixed, the center of the pointer 24 coincides with the center of the angle measuring scale 26, and the 0° scale line on the angle measuring scale 26 is located on the center line of the angle measuring scale 26. The lower edge of the panel 9 is aligned with the steel plate below, and the left side of the inspection rod 22 is aligned with another steel plate. If the two steel plates are not in a vertical state, the inspection rod 22 will be deflected, and the pointer 24 will be deflected synchronously with the inspection rod 22. Referring to the value pointed by the pointer 24, the angle formed between the two steel plates can be known.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
